Palmitoylation As A Regulator Of Maguk Proteins Postsynaptic Localization, Rozena Shirvani-Arani, Santiago Balderas, Yonghong Zhang, Xioaqian Fang
Research Symposium
Synaptic plasticity is the ability of the brain to make changes and the changes occur at synapses. To achieve the complicated functions, a good number of proteins are present at synapse and are called synaptic proteins. To stabilize these proteins at synapses, proteins are modified through posttranslational modifications (PTMs). The most studied PTMs include phosphorylation, acetylation, ubiquitination, glycosylation, palmitoylation, etc. Palmitoylation is a type of lipid modification and has received more attention recently for its contribution to protein trafficking, localization, and interaction in various synaptic plasticity. The membrane-associated guanylate kinase (MAGUK) family includes PSD-95, PSD-93 (also known as chapsyn-110), SAP102, …
The Use Of Prognostic Markers To Predict Disease Progression And Clinical Outcome In Monoclonal Gammopathy Of Undetermined Significance, Smouldering Multiple Myeloma And Multiple Myeloma., Róisín C. Mcmonagle
The Use Of Prognostic Markers To Predict Disease Progression And Clinical Outcome In Monoclonal Gammopathy Of Undetermined Significance, Smouldering Multiple Myeloma And Multiple Myeloma., Róisín C. Mcmonagle
International Undergraduate Journal of Health Sciences
Multiple Myeloma (MM) is an incurable plasma cell malignancy with a complex and incompletely understood molecular pathogenesis. Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smouldering Multiple Myeloma (SMM) precede MM, with variable risks and rates of disease progression. The continuing high relapse and death rate in MM cases has prompted research into more accurate prognostic markers to predict progression from MGUS and SMM to MM, as well as identify MM cases with aggressive disease, in order to begin early, targeted and effective therapeutic intervention. Many studies have focused on utilising current markers more effectively, including M-protein, serum-free light chain ratio, …

Essential trace elements are required in extremely small amounts and obtained through diet. This research focuses on detecting major trace elements in different biofluids of sixty women undergoing ICSI with PGT-A and SET/FET at IVI-RMA, New Jersey, and assessing their impact on their IVF outcomes. Urine, plasma, and follicular fluid samples were collected on the vaginal oocyte retrieval day to measure the concentrations of eight essential trace elements (copper, zinc, molybdenum, lithium, selenium, manganese, chromium, and iron) using ICP-MS. After analysis, ovarian response and preimplantation outcomes had significant positive associations with both copper alone and the copper/zinc ratio in the …

Cardiovascular diseases (CVDs) still contribute as the main cause of mortality and premature mortality worldwide. In Indonesia, CVDs contribute to 35% of the main cause of death in non-communicable diseases followed by diabetes at 6%. The ischemic heart disease and acute ischemic stroke is the main cause of death in Indonesia due to atherosclerosis. Atherosclerosis is a multifactorial cause, with chronic inflammation which causes myocardial infarction and acute ischemic stroke. Research demonstrated that one of the underlying mechanisms of atherosclerosis is inflammation. The current research suggested that inflammation could activate a complex of cytosol proteins, namely nucleotide-binding oligomerization domain-like receptor …

Department of Pediatrics Faculty Papers
Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is caused by a deficiency of the N-acetylgalactosamine-6-sulfate-sulfatase (GALNS) enzyme, leading to the accumulation of glycosaminoglycans (GAG), keratan sulfate (KS) and chondroitin-6-sulfate (C6S), mainly in cartilage and bone. This lysosomal storage disorder (LSD) is characterized by severe systemic skeletal dysplasia. To this date, none of the treatment options for the MPS IVA patients correct bone pathology. Enzyme replacement therapy with elosulfase alpha provides a limited impact on bone growth and skeletal lesions in MPS IVA patients. To improve bone pathology, we propose a novel gene therapy with a small peptide as a growth-promoting …

Immunometabolic Reprogramming, Another Cancer Hallmark, Vijay Kumar, John H. Stewart
School of Medicine Faculty Publications
Molecular carcinogenesis is a multistep process that involves acquired abnormalities in key biological processes. The complexity of cancer pathogenesis is best illustrated in the six hallmarks of the cancer: (1) the development of self-sufficient growth signals, (2) the emergence of clones that are resistant to apoptosis, (3) resistance to the antigrowth signals, (4) neo-angiogenesis, (5) the invasion of normal tissue or spread to the distant organs, and (6) limitless replicative potential. It also appears that non-resolving inflammation leads to the dysregulation of immune cell metabolism and subsequent cancer progression. The present article delineates immunometabolic reprogramming as a critical hallmark of …

Cell reprogramming to a myofibroblast responsible for the pathological accumulation of extracellular matrix is fundamental to the onset of fibrosis. Here, we explored how condensed chromatin structure marked by H3K72me3 becomes modified to allow for activation of repressed genes to drive emergence of myofibroblasts. In the early stages of myofibroblast precursor cell differentiation, we discovered that H3K27me3 demethylase enzymes UTX/KDM6B creates a delay in the accumulation of H3K27me3 on nascent DNA revealing a period of decondensed chromatin structure. This period of decondensed nascent chromatin structure allows for binding of pro-fibrotic transcription factor, Myocardin-related transcription factor A (MRTF-A) to nascent DNA. …
Adipocytes And Innate Immunity In Systemic Sclerosis, Nancy Wareing
Adipocytes And Innate Immunity In Systemic Sclerosis, Nancy Wareing
Dissertations & Theses (Open Access)
Systemic sclerosis (SSc; scleroderma) is a chronic systemic autoimmune and connective tissue disorder characterized by vasculopathy, autoimmune phenomena, and widespread fibrosis. Skin thickening and tightening is the cardinal feature of SSc and is responsible, in part, for the considerable morbidity of this disease. There are currently no targeted treatments for skin manifestations in SSc, primarily due to our fragmented understanding of its pathophysiologic mechanisms. In PART I, we report a previously unappreciated link between aberrant expression of the developmental gene sine oculis homeobox homolog 1 (SIX1) in skin-associated adipocytes in SSc skin and the early loss of dermal white adipose …

Mild Traumatic Brain Injury (mild TBI)/concussion is a common sports injury, especially common in football players. Repeated concussions are thought to lead to long-term brain damage including chronic traumatic encephalopathy (CTE). With the worldwide growing interest in studying sport-related concussion the search for biomarkers for early diagnosis and progression of neuronal injury has also became priority. MicroRNAs are short, non-coding RNAs that regulate gene expression post-transcriptionally. Due to their high stability in biological fluids, microRNAs can serve as biomarkers in a variety of diseases including pathologies of the nervous system. In this exploratory study, we have evaluated changes in the …

Mechanisms Of Chromosomal Instability (Cin) Tolerance In Aggressive Tumors: Surviving The Genomic Chaos, Brittiny Dhital, Veronica Rodriguez-Bravo
Student Papers, Posters & Projects
Chromosomal instability (CIN) is a pervasive feature of human cancers involved in tumor initiation and progression and which is found elevated in metastatic stages. CIN can provide survival and adaptation advantages to human cancers. However, too much of a good thing may come at a high cost for tumor cells as excessive degree of CIN-induced chromosomal aberrations can be detrimental for cancer cell survival and proliferation. Thus, aggressive tumors adapt to cope with ongoing CIN and most likely develop unique susceptibilities that can be their Achilles' heel. Determining the differences between the tumor-promoting and tumor-suppressing effects of CIN at the …
Regeneration Of Neurons In Human Brain Tissue; A Revolutionary Concept With Therapeutic Potential, Mackenzie R. Dunn
Regeneration Of Neurons In Human Brain Tissue; A Revolutionary Concept With Therapeutic Potential, Mackenzie R. Dunn
Other Undergraduate Research
There is current research to suggest that endogenous neuronal regeneration, exogenous neuronal stem cell transplantation and glial cell reprogramming could be prospective therapeutic treatments for neurodegeneration and traumatic injury. With these conditions, there is significant brain atrophy, loss of neurons and loss of synaptic connections which can have devastating effects on executive functioning, cognition, learning and memory. This review will examine these modern approaches to adult neurogenesis, and assess the viable mechanisms and future outlook of these three therapies for neurological regenerative medicine.

Metastatic prostate cancer (PCa) inevitably acquires resistance to standard therapy preceding lethality. Here, we unveil a chromosomal instability (CIN) tolerance mechanism as a therapeutic vulnerability of therapy-refractory lethal PCa. Through genomic and transcriptomic analysis of patient datasets, we find that castration and chemotherapy-resistant tumors display the highest CIN and mitotic kinase levels. Functional genomics screening coupled with quantitative phosphoproteomics identify MASTL kinase as a survival vulnerability specific of chemotherapy-resistant PCa cells. Mechanistically, MASTL upregulation is driven by transcriptional rewiring mechanisms involving the non-canonical transcription factors androgen receptor splice variant 7 and E2F7 in a circuitry that restrains deleterious CIN and …
Molecular Mechanisms Of Prdm16 As A Tumor Suppressor In Pancreatic Ductal Adenocarcinoma, Eric Hurwitz
Molecular Mechanisms Of Prdm16 As A Tumor Suppressor In Pancreatic Ductal Adenocarcinoma, Eric Hurwitz
Theses and Dissertations
The transcription factor Prdm16 functions as a potent suppressor of transforming growth factor-beta (TGF-b) signaling, whose inactivation is deemed essential to the progression of pancreatic ductal adenocarcinoma (PDAC). Using the KrasG12D-based mouse model of human PDAC, we surprisingly found that ablating Prdm16 did not block but instead accelerated PDAC formation and progression, suggesting that Prdm16 might function as a tumor suppressor in this malignancy. Subsequent genetic experiments showed that ablating Prdm16 along with Smad4 resulted in a shift from a well-differentiated and confined neoplasm to a highly aggressive and metastatic disease, which was associated with a striking deviation …

Effect Of Stretch And Release On Myofascial Stem Cell Function In Vitro: A Putative Model To Understand The Molecular Benefits Of The Myofascial Release (Mfr) Technique, Ben Smith, Shahn Notta, Debasis Mondal
Research Day
Despite the beneficial effects of osteopathic manipulative techniques (OMT), there is a lack of in vitro models to understand the molecular mechanisms associated with these time-tested therapies. The Myofascial Release (MFR) technique is a non-invasive approach that involves passive stretching, hold and release, of the soft tissue to achieve myofascial homeostasis. Tissue-resident mesenchymal stem cells (MSC) can regulate the myofascial microenvironment by altering their secreted factors following stretch and release. Therefore, we initiated studies to develop an in vitro model to investigate the possible effects of stretch and release on MSC function, i.e. proliferation and differentiation capabilities, and changes in …
Review On Molecular Genetic Basis Of Hypertrophic Cardiomyopathy, Derek Pok Him Lee
Review On Molecular Genetic Basis Of Hypertrophic Cardiomyopathy, Derek Pok Him Lee
Journal of the Hong Kong College of Cardiology
Hypertrophic cardiomyopathy (HCM) is one of the most common types of inherited cardiomyopathy with a wide range of clinical manifestations ranging from subtle myocardial hypertrophy to debilitating heart failure, cardiac arrhythmias, and sudden cardiac death. We reviewed the literature on the latest knowledge regarding the pathophysiology and molecular genetic basis of HCM. This will include laboratory studies on animal models and human pluripotent stem-cell derived cardiomyocytes and the theory of proximal mechanisms involving calcium handling and energy expenditure underlying HCM. The current review will also illustrate the pathogenicity of various associated genetic variants, genotype-phenotype correlation and the optimal approach to …

A region on chromosome 21, the Down Syndrome critical region (DSCR), is associated with major defects found in Down Syndrome, such as craniofacial malformations. DYRK1A is a gene found on chromosome 21 within the DSCR that encodes an enzyme, dual specificity tyrosine-phosphorylation-regulated kinase 1A. DYRK1A is known to phosphorylate many substrate proteins and is thought to be involved in tumor suppression, neurological development, cell cycle regulation, and aging. Recently, the Litovchick lab and others reported that DYRK1A also plays a role in the double-strand break repair of DNA, which could lead to mutations and tumorigenesis, if deregulated.
