Deepep: A Deep Learning Framework For Identifying Essential Proteins, Min Zeng, Min Li, Fang-Xiang Wu, Yaohang Li, Yi Pan
Computer Science Faculty Publications
Background: Essential proteins are crucial for cellular life and thus, identification of essential proteins is an important topic and a challenging problem for researchers. Recently lots of computational approaches have been proposed to handle this problem. However, traditional centrality methods cannot fully represent the topological features of biological networks. In addition, identifying essential proteins is an imbalanced learning problem; but few current shallow machine learning-based methods are designed to handle the imbalanced characteristics. Results: We develop DeepEP based on a deep learning framework that uses the node2vec technique, multi-scale convolutional neural networks and a sampling technique to identify essential proteins ...

Maximizing the number of offspring born per female is a key functionality trait in commercial- and/or subsistence-oriented livestock enterprises. Although the number of offspring born is closely associated with female fertility and reproductive success, the genetic control of these traits remains poorly understood in sub-Saharan Africa livestock. Using selection signature analysis performed on Ovine HD BeadChip data from the prolific Bonga sheep in Ethiopia, 41 candidate regions under selection were identified. The analysis revealed one strong selection signature on a candidate region on chromosome X spanning BMP15, suggesting this to be the primary candidate prolificacy gene in the breed ...

Mapping Of Qtl And Identification Of Candidate Genes Conferring Spontaneous Haploid Genome Doubling In Maize (Zea Mays L.), Jiaojiao Ren, Nicholas Boerman, Ruixiang Liu, Penghao Wu, Benjamin Trampe, Kimberly Vanous, Ursula K. Frei, Shaojiang Chen, Thomas Lubberstedt
In vivo doubled haploid (DH) technology is widely used in commercial maize (Zea mays L.) breeding. Haploid genome doubling is a critical step in DH breeding. In this study, inbred lines GF1 (0.65), GF3(0.29), and GF5 (0) with high, moderate, and poor spontaneous haploid genome doubling (SHGD), respectively, were selected to develop mapping populations for SHGD. Three QTL, qshgd1, qshgd2, and qshgd3, related to SHGD were identified by selective genotyping. With the exception of qshgd3, the source of haploid genome doubling alleles were derived from GF1. Furthermore, RNA-Seq was conducted to identify putative candidate genes between GF1 ...

Cgste11 Mediates Cross Tolerance To Multiple Environmental Stressors In Candida Glabrata, 2019 Texas A&M University
Cgste11 Mediates Cross Tolerance To Multiple Environmental Stressors In Candida Glabrata, Mian Huang, Jibran Khan, Manpreet Kaur, Julian Daniel Torres Vanega, Orlando Andres Aguilar Patiño, Anand Ramasubramanian, Katy Kao
Faculty Publications, Biomedical, Chemical, and Materials Engineering
Candida glabrata is a human commensal and an opportunistic human fungal pathogen. It is more closely related to the model yeast Saccharomyces cerevisiae than other Candida spp. Compared with S. cerevisiae, C. glabrata exhibits higher innate tolerance to various environmental stressors, including hyperthermal stress. Here we investigate the molecular mechanisms of C. glabrata adaptation to heat stress via adaptive laboratory evolution. We show that all parallel evolved populations readily adapt to hyperthermal challenge (from 47 °C to 50 °C) and exhibit convergence in evolved phenotypes with extensive cross-tolerance to various other environmental stressors such as oxidants, acids, and alcohols.

Georgia Undergraduate Research Conference (GURC)
Today, consumers are more aware and demand more information about the foods they consume. Transgenic crops, such as BT-corn, are a popular topic of concern among an ever-growing population of health-conscious consumers. Additionally, many U.S. consumers are regularly going out to eat at restaurants instead of cooking at home, with about half of all U.S. food expenditures accounting for food-away-from home. Specifically, chips are becoming a staple of the current American diet and are popular amongst diverse demographics. This study is an attempt to discover if tortilla chips served in common U.S. restaurant chains are genetically modified ...

Georgia Undergraduate Research Conference (GURC)
There is a growing concern in the U.S. about genetically modified (GM) or GMO foods and consumers are demanding proper disclosure. Public Law 114-216 passed July 29, 2016 also known as the ‘GMO labeling bill’, where the USDA established a National Bioengineered Food Disclosure Standard (NBFDS) stating manufacturers are not required to label products if genetic material is undetected3. Bioengineered food is defined as a food that has been modified through the insertion of in vitro recombinant deoxyribonucleic acid techniques, per NBFDS. Because corn is currently in the bioengineered lists of crops and 93% of corn produced in ...

Label-Free Microrna Optical Biosensors, 2019 Old Dominion University
Label-Free Microrna Optical Biosensors, Meimei Lai, Gymama Slaughter
MicroRNAs (miRNAs) play crucial roles in regulating gene expression. Many studies show that miRNAs have been linked to almost all kinds of disease. In addition, miRNAs are well preserved in a variety of specimens, thereby making them ideal biomarkers for biosensing applications when compared to traditional protein biomarkers. Conventional biosensors for miRNA require fluorescent labeling, which is complicated, time-consuming, laborious, costly, and exhibits low sensitivity. The detection of miRNA remains a big challenge due to their intrinsic properties such as small sizes, low abundance, and high sequence similarity. A label-free biosensor can simplify the assay and enable the direct detection ...
In Vitro Investigation Of The Effect Of Camel Milkproteins And Its Fractions On Insulin Receptor Function, 2019 United Arab Emirates University
In Vitro Investigation Of The Effect Of Camel Milkproteins And Its Fractions On Insulin Receptor Function, Arshida Ashraf
Camel milk (CM) has been reported to have anti-diabetic properties in many in vitro and in vivo studies but the molecular basis of such beneficial properties are still elusive. Recently, camel milk whey proteins (CWPs) have been shown to positively affect the activity of the human insulin receptor (hIR) in cell lines. In this study, we profiled crude CWPs and their hydrolysates as well as camel milk lactoferrin (CMLF) for their pharmacological and functional effects on hIR activity and its downstream signaling in both human embryonic kidney (HEK293) and hepatocarcinoma (HepG2) cell lines. For this, bioluminescence resonance energy transfer (BRET ...

Forensic Evaluation Of 6-Dye Chemistry Kit Composed Of 23 Loi With Casework Samples, Naeema Saleh Al Janaahi
Short Tandem Repeats (STRs) are short nucleotide sequence repeats consisting of 2-8 base pairs (bp), representing approximately 3% of human DNA. Markers of STRs have been widely used as genetic markers in forensic DNA analysis and have proven to be an extremely discriminating method for human identification in forensics. The main objective of this research was to evaluate a six-dye STR multiplex assay (Virifiler™ Plus) composed of 23 autosomal STR loci, one insertion/deletion polymorphic marker on the Y chromosome, Amelogenin and two internal quality control markers (IQCS and IQCL) using biological stains found in different crime scenes. The study ...

Hypertension is one of the most prevalent diseases and is often called the "silent killer" because there are usually no early symptoms. Hypertension is also associated with multiple morbidities, including chronic kidney disease and cardiovascular disease. Early detection and intervention are therefore important. The current routine method for diagnosing hypertension is done using a sphygmomanometer, which can only provide intermittent blood pressure readings and can be confounded by various factors, such as white coat hypertension, time of day, exercise, or stress. Consequently, there is an increasing need for a non-invasive, cuff-less, and continuous blood pressure monitoring device. Multi-site photoplethysmography (PPG ...

Biochemistry -- Faculty Publications
Microalgae accumulate lipids during stress such as that of nutrient deprivation, concomitant with cessation of growth and depletion of chloroplasts. By contrast, certain small chemical compounds selected by high-throughput screening in Chlamydomonas reinhardtii can induce lipid accumulation during growth, maintaining biomass. Comprehensive pathway analyses using proteomics, transcriptomics, and metabolomics data were acquired from Chlamydomonas cells grown in the presence of one of two structurally distinct lipid activators. WD10784 stimulates both starch and lipid accumulation, whereas WD30030-treated cells accumulate only lipids. The differences in starch accumulation are largely due to differential effects of the two compounds on substrate levels that feed ...
The Catalytic Urease Subunit Urec Is Critical For Bifidobacterium Longum Urea Utilization, 2019 University of Massachusetts Amherst
The Catalytic Urease Subunit Urec Is Critical For Bifidobacterium Longum Urea Utilization, Yang Lyu
In the first study, we investigated the utilization of a human milk nitrogen source, urea, by Bifidobacterium. Urea accounts for ~15% in human milk, which is an abundant non-protein nitrogen (NPN). Some bifidobacteria are found to harbor urease gene clusters that potentially enable their hydrolysis of the human milk urea. However, the underlying mechanisms are still unclear. To incisively link the urease gene cluster with bifidobacterial urea utilization, chemical mutagenesis (i.e. ethyl methanesulfonate) was performed on the urease-positive Bifidobacterium longum subsp. suis UMA399. Mutants were selected on differential media and genetic lesions were identified using whole genome sequencing. A ...
Engineering Of An Antibody-Conjugated Nanogel Platform For Targeted Drug Delivery To T Lymphocytes, 2019 University of Massachusetts Amherst
Engineering Of An Antibody-Conjugated Nanogel Platform For Targeted Drug Delivery To T Lymphocytes, Mine Canakci
In an ideal chemotherapy, cytotoxic drugs travel through the bloodstream, reach cells all over the body and preferentially kill abnormal cells. Yet, the hydrophilic or lipophilic property of the small-molecule drugs affects their ability to reach cells from the bloodstream. So, only a small portion of the drug reaches to the diseased tissue. A selective cell killing approach for cancer therapy gained momentum after the realization that cancer cells carry unique set of molecular markers on their cell surface. The development of antibody drug conjugates (ADC) revolutionized the targeted approach for drug delivery. ADCs are composed of cytotoxic agents covalently ...
Investigating The Role Of Lbh During Early Embryonic Development In Xenopus Laevis, 2019 University of Massachusetts Amherst
Investigating The Role Of Lbh During Early Embryonic Development In Xenopus Laevis, Emma Weir
LBH is a highly conserved protein whose role during vertebrate development is relatively under-studied. In collaboration with the Albertson lab, our lab has previously shown that it is necessary for cranial neural crest cell migration in the zebrafish and in Xenopus laevis. The molecular mechanisms through which it acts are not well understood.
In Xenopus, LBH is a maternally deposited protein. As such, studying its role in early development has not been feasible through the morpholino-mediated knockdown techniques that prevent translation of target genes. Recently, a technique for degrading endogenous proteins was developed, called Trim-Away. This was developed in mammalian ...

Climatic adaptation is an example of a genotype-by-environment interaction (G×E) of fitness. Selection upon gene expression regulatory variation can contribute to adaptive phenotypic diversity; however, surprisingly few studies have examined how genome-wide patterns of gene expression G×E are manifested in response to environmental stress and other selective agents that cause climatic adaptation. Here, we characterize drought-responsive expression divergence between upland (drought-adapted) and lowland (mesic) ecotypes of the perennial C4 grass, Panicum hallii, in natural field conditions. Overall, we find that cis-regulatory elements contributed to gene expression divergence across 47% of genes, 7.2% of which exhibit ...
Heterologous Expression Of Secreted Bacterial Bpp And Hap Phytases In Plants Stimulates Arabidopsis Thaliana Growth On Phytate., Lia R. Valeeva, Chuluuntsetseg Nyamsuren, Margarita R. Sharipova, Eugene V. Shakirov
Yevgeniy (Eugene) Shakirov
Phytases are specialized phosphatases capable of releasing inorganic phosphate from myo-inositol hexakisphosphate (phytate), which is highly abundant in many soils. As inorganic phosphorus reserves decrease over time in many agricultural soils, genetic manipulation of plants to enable secretion of potent phytases into the rhizosphere has been proposed as a promising approach to improve plant phosphorus nutrition. Several families of biotechnologically important phytases have been discovered and characterized, but little data are available on which phytase families can offer the most benefits toward improving plant phosphorus intake. We have developed transgenic Arabidopsis thaliana plants expressing bacterial phytases PaPhyC (HAP family ...
