Pvsripo Effect On Cancer, Vishal Jindal, Matthew Lee, Darshan Rola, Mir Saleem

Biology Faculty Articles

PVSRIPO, a variant of the poliovirus, is a revolutionary virus that demonstrates key characteristics for oncolytic virotherapy due to its ability to attack glioblastomas. The first criteria that PVSRIPO demonstrates is tumor-targeting tropism. PVSRIPO binds to nectin-like molecule 5 (Necl-5), a poliovirus receptor (PVR), found on different types of cancers such as lung cancer, colorectal cancer, and glioblastomas. This allows the virus to have a high binding affinity to tumor cells. Secondly, after modifying the poliovirus by substituting its internal ribosome entry site (IRES) with the Human Rhinovirus 2's (HRV2) IRES, the poliovirus becomes PVSRIPO, an attenuated version of the …

A Physical And Genetic Map Of Cannabis Sativa Identifies Extensive Rearrangements At The Thc/Cbd Acid Synthase Loci, Kaitlin Laverty, Jake Stout, Mitchell Sullivan, Hardik Shah, Navdeep Gill, Larry Holbrook, Gintaras Deikus, Robert Sebra, Timothy Hughes, Jonathan Page, Harm Van Bakel

Biology Faculty Articles

Cannabis sativa is widely cultivated for medicinal, food, industrial, and recreational use, but much remains unknown regarding its genetics, including the molecular determinants of cannabinoid content. Here, we describe a combined physical and genetic map derived from a cross between the drug-type strain Purple Kush and the hemp variety “Finola.” The map reveals that cannabinoid biosynthesis genes are generally unlinked but that aromatic prenyltransferase (AP), which produces the substrate for THCA and CBDA synthases (THCAS and CBDAS), is tightly linked to a known marker for total cannabinoid content. We further identify the gene encoding CBCA synthase (CBCAS …

Role Of Genes In Obesity, Hanna Mathew, Mir Saleem

Biology Faculty Articles

Obesity is the outcome of an extreme difference between the energy intake and the energy expended, which leads to severe weight gain. The two main factors of obesity are environmental influences and genetics, but the extent of the genetic contribution to obesity continues to be unknown. Multiple studies using different tools have been used to support the significance of the genetic influence on obesity, such as twin and adoption studies, race/ethnicity, and mouse models. The use of mouse models has allowed for the greatest expansion of knowledge on the genetics behind obesity, and advancements continue to be made to this …

Comparison Of Two Ancient Dna Extraction Protocols For Skeletal Remains From Tropical Environments, Maria A. Nieves-Colon, Andrew T. Ozga, William J. Pestle, Andrea Cucina, Vera Tiesler, Travis W. Stanton, Anne C. Stone

Biology Faculty Articles

Objectives

The tropics harbor a large part of the world's biodiversity and have a long history of human habitation. However, paleogenomics research in these climates has been constrained so far by poor ancient DNA yields. Here we compare the performance of two DNA extraction methods on ancient samples of teeth and petrous portions excavated from tropical and semi‐tropical sites in Tanzania, Mexico, and Puerto Rico (N = 12).

Materials and Methods

All samples were extracted twice, built into double‐stranded sequencing libraries, and shotgun sequenced on the Illumina HiSeq 2500. The first extraction protocol, Method D, was previously designed for …

Dental calculus (calcified dental plaque) is prevalent in archaeological skeletal collections and is a rich source of oral microbiome and host-derived ancient biomolecules. Recently, it has been proposed that dental calculus may provide a more robust environment for DNA preservation than other skeletal remains, but this has not been systematically tested. In this study, shotgun-sequenced data from paired dental calculus and dentin samples from 48 globally distributed individuals are compared using a metagenomic approach. Overall, we find DNA from dental calculus is consistently more abundant and less contaminated than DNA from dentin. The majority of DNA in dental calculus is …

Hypocrisy And Corruption: How Disparities In Power Shape The Evolution Of Social Control, Omar T. Eldakar, J. Oliver Kammeyer, Nikhil Nagabandi, Andrew C. Gallup

Biology Faculty Articles

Altruism presents an evolutionary paradox, as altruistic individuals are good for the group yet vulnerable to exploitation by selfish individuals. One mechanism that can effectively curtail selfishness within groups is punishment. Here, we show in an evolutionary game-theoretical model that punishment can effectively evolve and maintain high levels of altruism in the population, yet not all punishment strategies were equally virtuous. Unlike typical models of social evolution, we explicitly altered the extent to which individuals vary in their power over others, such that powerful individuals can more readily punish and escape the punishment of others. Two primary findings emerged. Under …

One out of every six American women has been the victim of a sexual assault in their lifetime. However, the DNA casework backlog continues to increase outpacing the nation's capacity since DNA evidence processing in sexual assault casework remains a bottleneck due to laborious and time‐consuming differential extraction of victim's and perpetrator's cells. Additionally, a significant amount (60–90%) of male DNA evidence may be lost with existing procedures. Here, a microfluidic method is developed that selectively captures sperm using a unique oligosaccharide sequence (Sialyl‐LewisX), a major carbohydrate ligand for sperm‐egg binding. This method is validated with forensic mock samples dating …

Periodontitis In Patients With Type 2 Diabetes Mellitus, Simran Agarwal, Deepthi Gangaram, Mir Saleem

Biology Faculty Articles

Periodontitis is a chronic, inflammatory disease that is characterized by swollen gums, degradation of jaw structure, and potentially tooth loss. Like Periodontitis, Type 2 Diabetes Mellitus is also highly prevalent and largely multifactorial. Type 2 Diabetes is a condition in which higher than normal blood glucose levels cannot be properly maintained as the body’s normal mechanism of maintaining proper blood glucose levels, the release of insulin from pancreatic islet β-cells, becomes ineffective. The purpose of this literature review is to explore the relationship between the incidences of Periodontitis and Type 2 Diabetes. The risk that Type 2 Diabetes poses for …

We report a large compilation of the internal validations of the probabilistic genotyping software STRmix™. Thirty one laboratories contributed data resulting in 2825 mixtures comprising three to six donors and a wide range of multiplex, equipment, mixture proportions and templates. Previously reported trends in the LR were confirmed including less discriminatory LRs occurring both for donors and non-donors at low template (for the donor in question) and at high contributor number. We were unable to isolate an effect of allelic sharing. Any apparent effect appears to be largely confounded with increased contributor number.

Deep-Sea Hydrothermal Vents As Natural Egg-Case Incubators At The Galapagos Rift, Pelayo Salinas-De-Leon, Brennan Phillips, David A. Ebert, Mahmood S. Shivji, Florencia Cerutti-Pereyra, Cassandra Ruck, Charles R. Fisher, Leigh Marsh

Biology Faculty Articles

The discovery of deep-sea hydrothermal vents in 1977 challenged our views of ecosystem functioning and yet, the research conducted at these extreme and logistically challenging environments still continues to reveal unique biological processes. Here, we report for the first time, a unique behavior where the deep-sea skate, Bathyraja spinosissima, appears to be actively using the elevated temperature of a hydrothermal vent environment to naturally “incubate” developing egg-cases. We hypothesize that this behavior is directly targeted to accelerate embryo development time given that deep-sea skates have some of the longest egg incubation times reported for the animal kingdom. Similar egg …

Pulmonary Alveolar Proteinosis- A Case Report, Renee M. Horner, Douglas S. Gardenhire, Ralph D. Zimmerman

Internet Journal of Allied Health Sciences and Practice

ABSTRACT

Background: Pulmonary Alveolar Proteinosis (PAP) is a rare pulmonary disorder caused by a congregation of excessive lipoproteinaceous material in the alveolar spaces due to impaired surfactant metabolism. The congregation of the protein in the alveolar space leads to difficulty in breathing, impaired pulmonary immunity, and susceptibility to both opportunistic and acquired pulmonary infections. Although Pulmonary Alveolar Proteinosis is rare, there are potential treatments. Whole-lung lavage is the most widely accepted therapy and course of treatment. An additional form of therapy, GM-CSF stimulating therapy, uses recombinant deoxyribonucleic acid (DNA) technology to increase white cell production.

Purpose: The purpose …
