Androgen Receptor And Prostate Cancer Cell Heterogeneity, Qu Deng

Dissertations and Theses (Open Access)

Androgen receptor (AR) plays an important role in prostate cancer (PCa) development and has been the main therapeutic target in advanced PCa. AR expression is heterogeneous in both primary PCa and castration resistant prostate cancer (CRPC). However, the functional significance of AR heterogeneity in regulating PCa biology and response to androgen/AR-targeted therapies remains unclear. The overarching hypothesis for my Ph.D is that AR heterogeneity contributes to PCa development, progression, and therapy resistance. A more specific postulate is that PCa cells expressing AR (i.e, AR⁺) and PCa cells expressing little AR (i.e, AR^-/lo) possess intrinsically distinct …

Proteomic Identification Of Histone Post-Translational Modifications Induced By Dna Double-Strand Breaks And Novel Proteins Involved In The Dna Damage Response, Pingping Wang

Dissertations and Theses (Open Access)

Inaccurate repair of DNA double-strand breaks (DSBs) can lead to DNA mutation and chromosome rearrangements, causing human diseases such as cancer. Although we know the basic mechanisms of DSB repair, the added complexities in the chromatin context are unclear. This is partially due to the lack of unbiased systems for identifying proteins and post-translational modifications (PTMs) involved in DSB repair. In this work, we established a novel method, termed DSB-ChAP-MS (Double Strand Break-Chromatin Affinity Purification with Mass Spectrometry), for the affinity purification of a sequence-specific single copy endogenous chromosomal locus containing a DSB, followed by the proteomic identification of enriched …

Dissertations and Theses (Open Access)

NON-CODING RNAS IDENTIFY THE INTRINSIC MOLECULAR SUBTYPES OF MUSCLE-INVASIVE BLADDER CANCER

Andrea Elizabeth Ochoa, B.S.

Advisory Professors: David J. McConkey, Ph.D. and Joya Chandra, Ph.D.

There has been a recent explosion of genomics data in muscle-invasive bladder cancer (MIBC) to better understand the underlying biology of the disease that leads to the high amount of heterogeneity that is seen clinically. These studies have identified relatively stable intrinsic molecular subtypes of MIBC that show similarities to the basal and luminal subtypes of breast cancer. However, previous studies have primarily focused on protein-coding genes or DNA mutations/alterations.

There is emerging evidence implicating …

Investigation Of The Roles Of Asf1 And Caf-1-Mediated Chromatin Assembly In The Human Dna Damage Response, Ting-Hsiang Huang

Dissertations and Theses (Open Access)

The access-repair-restore model for the role of chromatin in DNA repair infers that chromatin is a mere obstacle to DNA repair. However, here we show that blocking chromatin assembly of newly-synthesized histones, via knockdown of the histone chaperones ASF1A, CAF-1 or a mutation that specifically prevents ASF1 binding to histones, hinders loading of Rad51 onto ssDNA during homologous recombination, as a consequence of reduced recruitment of the Rad51 loader MMS22L/TONSL to ssDNA, resulting in persistent RPA foci, extensive DNA end-resection, and persistent activation of the ATR-Chk1 pathway. By contrast, ASF1 and CAF-1 render the rapid inactivation of ATM Chk2 pathway …

Characterization Of The Ubiquitin Ligase, Ube4b, In Endocytic Trafficking, Natalie Sirisaengtaksin, Natalie Sirisaengtaksin

Dissertations and Theses (Open Access)

Endocytosis is a process by which cells internalize membrane proteins to remove them from the plasma membrane, allowing cells to regulate the cell surface expression of transmembrane proteins. In this manner, cellular responses to extracellular cues may be tuned by limiting the number of proteins available at the cell surface. One particular class of proteins, receptor tyrosine kinases (RTK), is internalized upon binding to extracellular ligands during their residence at the cell surface. The epidermal growth factor receptor (EGFR) is an RTK whose trafficking through the endocytic pathway through the cell is well-documented. Stimulation of EGFR with its cognate ligand, …

The Role Of Adenosine Signaling In Mature Erythrocytes And Erythroid Progenitors, Hong Liu

Dissertations and Theses (Open Access)

Adenosine is a ubiquitous nucleoside in almost all the cells throughout our bodies. It is highly induced particularly under hypoxia or energy depletion conditions. Adenosine functions as a critical ligand, after binding to membrane-associated adenosine receptors, adenosine initiates a downstream signaling cascade and subsequently contributes to functions of nervous system, immune response, vascular function and even metabolism.

Hypoxia is a condition with limited O₂ availability in the whole body or a region of the body. It is a major consequence of many respiratory and cardiovascular diseases, as well as for people living and working at high altitudes or other …

Understanding The Mechanism Of Genomic Instability During Replicative Aging In Budding Yeast, Sangita Pal

Dissertations and Theses (Open Access)

Aging brings a gradual decline in molecular fidelity and biological functionality, resulting in age related phenotypes and diseases. Despite continued efforts to uncover the conserved aging pathways among eukaryotes, exact molecular causes of aging are still poorly understood. One of the most important hallmarks of aging is increased genomic instability. However, there remains much ambiguity as to the cause. I am studying the replicative life span (RLS) of the genetically tractable model organism Saccharomyces cerevisiae, or budding yeast using the innovative “mother enrichment program” as the method to isolate unparalleled numbers of aged yeast cells to investigate the molecular changes …

Targeting Autophagy To Improve Efficacy Of Cdk4/6 Inhibition In Breast Cancer, Smruthi Vijayaraghavan

Dissertations and Theses (Open Access)

Deregulation of the cell cycle machinery is a hallmark of cancer, leading to aberrant proliferation and tumorigenesis. The crucial role of the CDK4/6-Cyclin D pathway has led to the development and FDA approval (palbociclib, ribociclib) of CDK4/6 inhibitors for the treatment of advanced estrogen receptor positive breast cancer. However, three major clinical challenges remain: i) adverse events leading to discontinuation of therapy and ii) lack of reliable biomarkers to identify responsive patients and iii) acquired resistance to CDK4/6 inhibitors. Previous in vitro studies have shown that palbociclib mediated CDK4/6 inhibition induces G1 arrest and senescence in ER+ breast cancer cells, …

Stromal Fibroblasts Restrain The Rate Of Colon Cancer Progression And Metastasis By Suppressing Regulatory T Cells And Colon Cancer Stem Cells, Changsoo Kwak

Dissertations and Theses (Open Access)

The initiation, progression, and metastasis of tumors involve not only cancer cells, but also the tumor microenvironment, which consists of immune or inflammatory cells, fibroblasts, endothelial cells, and extracellular matrix components (ECM). Fibroblasts are ubiquitous stromal cells that can influence other neighboring cell types through the secretion of chemokines, cytokines, ECM, ECM remodeling enzymes, and other metabolites. Myofibroblasts are a distinct subtype of fibroblasts characterized by expression α-smooth muscle actin (αSMA). These cells are a dominant component of the microenvironment, and a FSP1 and FAP could be a different clone of fibroblasts. Myofibroblasts also have been known to contribute to …

Annual Wormwood Leaf Inhibits The Adipogenesis Of 3t3-L1 And Obesity In High-Fat Diet-Induced Obese Rats, Y Song, S Lee, S Jang, T Kim, Hong-Duck Kim, S Kim, C Won, J Cho

NYMC Faculty Publications

Annual wormwood (AW) (Artemisia annua L.) has anti-malarial, anti-bacterial, anti-oxidant, anti-tumour, and anti-inflammatory activities. In the present study, we evaluated the effects of annual wormwood leaves (AWL) on adipocyte differentiation in 3T3-L1 cells and high-fat diet (HFD)-induced obese rats. 3T3-L1 adipocytes and HFD-induced obese rats were treated with AWL, and its effect on gene expression was analyzed using RT-PCR and Western blotting experiments. Treatment with AWL effectively prevented triglyceride accumulation during adipogenesis in a dose-dependent manner. Consistently, AWL suppressed the differentiation of 3T3-L1 preadipocytes into adipocytes through the downregulation of dexamethasone, 3-isobutyl-1- methylxanthine, and insulin (DMI)-induced serine/threonine kinase protein kinase …

Using Rb-Tnseq To Analyze Natural Variation In Saccharomyces Cerevisiae, Syed Raza Mahmood

Graduate Theses and Dissertations

One of the main challenges in biology today is the characterization of millions of genes of unknown function being continuously identified in sequencing studies. Transposon mutagenesis is a technique that has been widely used for annotating gene function and has now been combined with next-generation sequencing (Tn-Seq) to assess mutant fitness on a genome wide basis. However, Tn-Seq approaches are often constrained by laborious library preparation protocols which limit the number of organisms or conditions that can be assessed. Random bar code transposon-site sequencing (RB-TnSeq), is a transposon sequencing technique that streamlines library preparation and increases the throughput of mutant …

Thylakoid Protein Targeting/Insertion By A Signal Recognition Particle In Chloroplasts, Priyanka Sharma

Graduate Theses and Dissertations

Protein targeting is a fundamental cellular process that directs proteins from their site of synthesis to the site where they function. The signal recognition particle (SRP) dependent targeting pathway is conserved in both eukaryotes and prokaryotes where it co-translationally targets polypeptide chains emerging from ribosomes to the endoplasmic reticulum (eukaryotes) or cytoplasmic membrane (prokaryotes). A structurally unique form of SRP is found in chloroplasts where it functions to post-translationally bind and target a subset of integral thylakoid membrane proteins, the light harvesting chlorophyll binding proteins (LHCPs). Mature LHCPs bind chlorophyll a/b and function in photosynthetic light capture. Like many other …

The Role Of Col11a1 Expression During Cartilage Development, Jonathon Charles Reeck

Boise State University Theses and Dissertations

It is currently a major scientific and medical goal to identify and characterize genetic defects and their impact in health and disease. For example, mutations in genes that encode collagen alpha chains can cause skeletal dysplasia and lead to premature degenerative joint disease. Collagen is the main structural protein in the ECM of connective tissues such as the cartilage, joints, ligaments and tendons. Therefore, the goal of this research is to define the impact of the alpha one chain of collagen type XI chain, encoded by the COL11A1 gene in humans, on chondrocyte behavior during development of the cartilage. We …

Melatonin And Its Metabolites Protect Human Melanocytes Against Uvb-Induced Damage: Involvement Of Nrf2-Mediated Pathways, Zorica Janjetovic, Stuart G. Jarrett, Elizabeth F. Lee, Cory Duprey, Russel J. Reiter, Andrzej T. Slominski

Toxicology and Cancer Biology Faculty Publications

Ultraviolet light (UV) is an inducer of reactive oxygen species (ROS) as well as 6-4-photoproducts and cyclobutane pyrimidine dimers (CPD) in the skin, which further cause damage to the skin cells. Irradiation of cultured human melanocytes with UVB stimulated ROS production, which was reduced in cells treated with melatonin or its metabolites: 6-hydroxymelatonin (6-OHM), N1-acetyl-N2-formyl-5-methoxykynuramine (AFMK), N-acetylserotonin (NAS), and 5-methoxytryptamine (5-MT). Melatonin and its derivatives also stimulated the expression of NRF2 (nuclear factor erythroid 2 [NF-E2]-related factor 2) and its target enzymes and proteins that play an important role in cell protection from different damaging factors including UVB. Silencing …

Bk Channels Mediate Synaptic Plasticity Underlying Habituation In Rats, Tariq Zaman, Cleusa De Oliveira, Mahabba Smoka, Chakravarthi Narla, Michael O. Poulter, Susanne Schmid

Anatomy and Cell Biology Publications

Habituation is a basic form of implicit learning and represents a sensory filter that is disrupted in autism, schizophrenia, and several other mental disorders. Despite extensive research in the past decades on habituation of startle and other escape responses, the underlying neural mechanisms are still not fully understood. There is evidence from previous studies indicating that BK channels might play a critical role in habituation. We here used a wide array of approaches to test this hypothesis. We show that BK channel activation and subsequent phosphorylation of these channels are essential for synaptic depression presumably underlying startle habituation in rats, …

Activity Of Distinct Growth Factor Receptor Network Components In Breast Tumors Uncovers Two Biologically Relevant Subtypes, Moom Roosan, Shelley M. Macneil, David F. Jenkins, Gajendra Shrestha, Sydney R. Wyatt, Jasmine A. Mcquerry, Stephen R. Piccolo, Laura M. Heiser, Joe W. Gray, W. Evan Johnson, Andrea H. Bild

Pharmacy Faculty Articles and Research

Background
The growth factor receptor network (GFRN) plays a significant role in driving key oncogenic processes. However, assessment of global GFRN activity is challenging due to complex crosstalk among GFRN components, or pathways, and the inability to study complex signaling networks in patient tumors. Here, pathway-specific genomic signatures were used to interrogate GFRN activity in breast tumors and the consequent phenotypic impact of GRFN activity patterns.

Methods
Novel pathway signatures were generated in human primary mammary epithelial cells by overexpressing key genes from GFRN pathways (HER2, IGF1R, AKT1, EGFR, KRAS (G12V), RAF1, BAD). The pathway analysis toolkit Adaptive Signature Selection …

Nucleic Acid Combinations: A New Frontier For Cancer Treatment, K. C. Remant Bahadur, Bindu Thapa, Juliana Valencia-Serna, Hamidreza Montazeri Aliabadi, Hasan Uludağ

Pharmacy Faculty Articles and Research

The emerging molecular understanding of cancer cell behavior is leading to increasing possibilities to control unchecked cell growth and metastasis. On the other hand, development of multifunctional drug carriers at the ‘nano’-scale is providing exciting new therapeutic strategies in clinical management of cancer beyond the conventional cytotoxic drugs. A new frontier in this regard is the combinational use of complementary agents based on nucleic acids to overcome the limitations of conventional therapy. The existence of tightly-integrated cross-talk through multiple signaling and effector pathways has been appreciated for some time, and the plasticity of such a network to overcome one-dimensional intervention …

Transcriptomic Analysis Of Maternally Provisioned Cues For Phenotypic Plasticity In The Annual Killifish, Austrofundulus Limnaeus, Amie L. Romney, Jason E. Podrabsky

Biology Faculty Publications and Presentations

Background: Genotype and environment can interact during development to produce novel adaptive traits that support life in extreme conditions. The development of the annual killifsh Austrofundulus limnaeus is unique among vertebrates because the embryos have distinct cell movements that separate epiboly from axis formation during early development, can enter into a state of metabolic dormancy known as diapause and can survive extreme environmental conditions. The ability to enter into diapause can be maternally programmed, with young females producing embryos that do not enter into diapause. Alternately, embryos can be programmed to “escape” from diapause and develop directly by both maternal …

The Addition Of Arachidin 1 Or Arachidin 3 To Human Rotavirus-Infected Cells Inhibits Viral Replication And Alters The Apoptotic Cell Death Pathway, Macie N. Mattila, Caleb M. Witcher, Rebekah Napier-Jameson, Hannah N. Lockwood, Josephine Taylor, Beatrice A. Clack, Judith M. Ball, Fabricio Medina Bolivar, Rebecca D. Parr

Undergraduate Research Conference

Rotavirus (RV) infections are a leading cause of severe gastroenteritis in infants and children under the age of five. There are two vaccines available in the United States and one in India that can be administered early in childhood, however they only protect against specific strains1. From our previous work, both arachidin-1 (A1) and arachidin-3 (A3) from peanut (Arachis hypogaea) hairy root cultures significantly inhibit simian RV replication2,3,4. The purpose of this study was to determine if a human intestinal cell line, HT29.f8, infected with a human RV, Wa, was affected by A1 and A3. Cell viability assays were utilized …

Identification Of Novel Interactors Of Sec6 Via Genetic Suppressor Screen Using A Saccharomyces Cerevisiae Genomic Dna Library, Y. Ellen France Phd, Emily Parrish, Raira Ank, Tristan Peterman, Sarah Mork, Billie Mills, Lindsey Duke, Jyoti Lama

Georgia College Student Research Events

Polarized protein secretion is a fundamental process for all organisms, from yeast to higher eukaryotes. The secretory pathway in eukaryotes includes many steps mediated by hundreds of essential proteins. Our interest lies on Sec6, which is an 88kDa protein subunit of the tethering complex named exocyst, which is known to play diverse roles in recognition, tethering, and SNARE-mediated fusion of secretory vesicles. Previous work on Sec6 done by Munson and Songer (2009) explored phenotypes of two novel SEC6 mutant proteins, whose conserved surface amino acids had been altered. Both sec6-49 and sec6-54 mutant alleles displayed severe temperature sensitive growth and …

Lysine Residues Of Interferon Regulatory Factor 7 Affect The Replication And Transcription Activatormediated Lytic Replication Of Kaposi’S Sarcomaassociated Herpesvirus/Human Herpesvirus 8, Tianzheng Zhang, Ying Wang, Li Zhang, Bin Liu, Jinhui Xie, Charles Wood, Jinzhong Wang

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) infection goes through latent and lytic phases, which are controlled by the viral replication and transcription activator (RTA). Upon KSHV infection, the host responds by suppressing RTA-activated lytic gene expression through interferon regulatory factor 7 (IRF-7), a key regulator of host innate immune response. Lysine residues are potential sites for post-translational modification of IRF-7, and were suggested to be critical for its activity. In this study, we analysed the 15 lysine residues for their effects on IRF-7 function by site-directed mutagenesis. We found that some mutations affect the ability of IRF-7 to activate interferon (IFN)-a1 and …

Granulosa Cell Endothelin-2 Expression Is Fundamental For Ovulatory Follicle Rupture, Joseph A. Cacioppo, Po-Ching Patrick Lin, Patrick R. Hannon, Daniel R. Mcdougle, Arnon Gal, Chemyong Ko

Obstetrics and Gynecology Faculty Publications

Ovulation is dependent upon numerous factors mediating follicular growth, vascularization, and ultimately oocyte release via follicle rupture. Endothelin-2 (EDN2) is a potent vasoconstrictor that is transiently produced prior to follicle rupture by granulosa cells of periovulatory follicles and induces ovarian contraction. To determine the role of Edn2 expression, surgical transplant and novel conditional knockout mice were super-ovulated and analyzed. Conditional knockout mice utilized a new iCre driven by the Esr2 promoter to selectively remove Edn2. Follicle rupture and fertility were significantly impaired in the absence of ovarian Edn2 expression. When ovaries of Edn2KO mice were transplanted in wild type …

Mll3/Mll4 Are Required For Cbp/P300 Binding On Enhancers And Super-Enhancer Formation In Brown Adipogenesis., Binbin Lai, Ji-Eun Lee, Younghoon Jang, Lifeng Wang, Weiqun Peng, Kai Ge

Anatomy and Regenerative Biology Faculty Publications

Histone H3K4me1/2 methyltransferases MLL3/MLL4 and H3K27 acetyltransferases CBP/p300 are major enhancer epigenomic writers. To understand how these epigenomic writers orchestrate enhancer landscapes in cell differentiation, we have profiled genomic binding of MLL4, CBP, lineage-determining transcription factors (EBF2, C/EBPβ, C/EBPα, PPARγ), coactivator MED1, RNA polymerase II, as well as epigenome (H3K4me1/2/3, H3K9me2, H3K27me3, H3K36me3, H3K27ac), transcriptome and chromatin opening during adipogenesis of immortalized preadipocytes derived from mouse brown adipose tissue (BAT). We show that MLL4 and CBP drive the dynamic enhancer epigenome, which correlates with the dynamic transcriptome. MLL3/MLL4 are required for CBP/p300 binding on enhancers activated during adipogenesis. Further, MLL4 …

Mating Patterns And Post-Mating Isolation In Three Cryptic Species Of The Engystomops Petersi Species Complex, Paula A. Trillo, Andrea E. Narvaez, Santiago R. Ron, Kim L. Hoke

Biology Faculty Publications

Determining the extent of reproductive isolation in cryptic species with dynamic geographic ranges can yield important insights into the processes that generate and maintain genetic divergence in the absence of severe geographic barriers. We studied mating patterns, propensity to hybridize in nature and subsequent fertilization rates, as well as survival and development of hybrid F₁ offspring for three nominal species of the Engystomops petersi species complex in Yasuní National Park, Ecuador. We found at least two species in four out of six locations sampled, and 14.3% of the wild pairs genotyped were mixed-species (heterospecific) crosses. We also found reduced …

Thujone Inhibits The Function Of Α7-Nicotinic Acetylcholine Receptors And Impairs Nicotine-Induced Memory Enhancement In One-Trial Passive Avoidance Paradigm, Ahmed Sultan, Keun-Hang Susan Yang, Dmytro Isaev, Eslam El Nebrisi, Nurulain Syed, Nadia Khan, Christopher F. Howarth, Bassem Sadek, Murat Oz

Mathematics, Physics, and Computer Science Faculty Articles and Research

Effects of thujone, a major ingredient of absinthe, wormwood oil and some herbal medicines, were tested on the function of α7 subunit of the human nicotinic acetylcholine (α7 nACh) receptor expressed in Xenopus oocytes using the two-electrode voltage-clamp technique. Thujone reversibly inhibited ACh (100 μM)-induced currents with an IC50 value of 24.7 μM. The effect of thujone was not dependent on the membrane potential and did not involve Ca2+-dependent Cl- channels expressed endogenously in oocytes. Inhibition by thujone was not reversed by increasing ACh concentrations. Moreover, specific binding of [125I] -bungarotoxin was not altered by thujone. Further experiments in SH-EP1 …

Uncovering Transcriptional Activators And Targets Of Hsf-1 In Caenorhabditis Elegans, Jessica Brunquell

USF Tampa Graduate Theses and Dissertations

In order to survive, cells must be able to cope with a variety of environmental stressors. The heat shock response (HSR) is a pro-survival mechanism employed by cells in response to protein denaturing stress, such as heat. Since its discovery in 1960, the heat shock response has been found to be regulated by the transcription factor heat shock factor 1 (HSF1). During periods of increased stress, HSF1 undergoes a multi-step process of activation that involves homotrimerization, DNA-binding, and post-translational regulatory modifications, all of which ultimately function to control the transcription of chaperone genes. These chaperone genes encode molecular chaperone proteins …

Acetaminophen Associated Neurotoxicity And Its Relevance To Neurodevelopmental Disorders, Seol-Hee Kim

USF Tampa Graduate Theses and Dissertations

Autism is a lifelong neurodevelopmental disorder. The etiology of autism still remains unclear due to the heterogeneous and complex nature of the disorder, however synergistic actions between genetic components and environmental factors have been suggested. Acetaminophen (APAP) is one of the most popular over-the-counter drugs that possess antipyretic and analgesic effects. It is considered a relatively safe and effective within therapeutic doses. Recently, early exposure to APAP has been suggested to be one of the underlying cause of autism. Children are often prescribed APAP to lessen fever or irritability after vaccination during the first year, and APAP may adversely affect …

C-Myc’S Role On Methylation Of The Gata-2 Gene In Non-Small Cell Lung Carcinoma, Jonathan D. Hajduk

Student Scholar Showcase

Lung cancer accounts for more deaths per year than any other form of cancer, resulting in a total of 158,000 deaths per year in the U.S. Non-small cell lung cancer (NSCLC) is diagnosed in greater than 224,000 Americans every year. Methylation and subsequent downregulation of certain genes has been directly linked to the uncontrolled growth of NSCLC cells. Natural killer (NK) cells are key innate immune cells responsible for apoptosis of cells with incorrect genetic code. It is believed that one component of uncontrolled NSCLC growth is due to the NK cells’ inability to detect errors within NSCLC cells. Perhaps …

Avian And Mammalian Facilitative Glucose Transporters, Mary Shannon Byers, Christianna Howard, Xiaofei Wang

Biology Faculty Research

The GLUT members belong to a family of glucose transporter proteins that facilitate glucose transport across the cell membrane. The mammalian GLUT family consists of thirteen members (GLUTs 1–12 and H+-myo-inositol transporter (HMIT)). Humans have a recently duplicated GLUT member, GLUT14. Avians express the majority of GLUT members. The arrangement of multiple GLUTs across all somatic tissues signifies the important role of glucose across all organisms. Defects in glucose transport have been linked to metabolic disorders, insulin resistance and diabetes. Despite the essential importance of these transporters, our knowledge regarding GLUT members in avians is fragmented. It is clear that …

Inquiry Into Perilipin-5a Expression In Triacylglycerol Rich Vs Normal Fed Mouse Tissue, Kobi Agyepong

Undergraduate Honors Thesis Projects

The steep rise in both childhood and adult obesity over the past three decades has moved to the forefront of public consciousness in recent years. This development has generated a marked increase in general health awareness and lifestyle changes for a vast number of individuals, most notably in the form of increased physical activity and diet alterations. The latter point is especially salient in a biochemical context, because of the myriad factors that can result in “fat accumulation”. Chief among these factors is the Perilipin 5A gene, (known as PLIN5A) which encodes the protein Perilipin 5A of the Perilipin family …
