Therapeutic strategies targeting the DNA damage response, such as poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi), have revolutionized cancer treatment in tumors deficient in homologous recombination (HR). However, overcoming innate and acquired resistance to PARPi remains a significant challenge. Here, we employ a genome-wide CRISPR knockout screen and discover that the depletion of ubiquitin-activating enzyme E1 (UBA1) enhances sensitivity to PARPi in HR-proficient ovarian cancer cells. We show that silencing or pharmacological inhibition of UBA1 sensitizes multiple cell lines and organoid models to PARPi. Mechanistic studies uncover that UBA1 inhibition not only impedes HR repair to sensitize cells to PARP inhibition …

Despite 96 million years of evolution separating humans and rodents, 11 closely related reproductive tract-specific genes in humans—SPINT3, WFDC6, EPPIN, WFDC8, WFDC9, WFDC10A, WFDC11, WFDC10B, WFDC13, SPINT4, and WFDC3—and the 13 reproductive tract-specific orthologous genes in mice, form highly conserved syntenic gene clusters indicative of conserved, combined critical functions. Further, despite significant progress toward a nonhormonal male contraceptive targeting the protein encoded by one of these genes, epididymal peptidase inhibitor (EPPIN), and associations found between mutations in EPPIN and an increased risk of male infertility, neither EPPIN nor …

The C-Terminal Activating Domain Promotes Pannexin 1 Channel Opening, Erik Henze, Jacqueline J Ehrlich, Janice L Robertson, Eric Gelsleichter, Toshimitsu Kawate

2020-Current year OA Pubs

Pannexin 1 (Panx1) constitutes a large pore channel responsible for the release of adenosine triphosphate (ATP) from apoptotic cells. Strong evidence indicates that caspase-mediated cleavage of the C-terminus promotes the opening of the Panx1 channel by unplugging the pore. However, this simple pore-plugging mechanism alone cannot account for the observation that a Panx1 construct ending before the caspase cleavage site remains closed. Here, we show that a helical region located immediately before the caspase cleavage site, referred to as the "C-terminal activating domain (CAD)", plays a pivotal role in facilitating Panx1 activation. Electrophysiology and mutagenesis studies uncovered that two conserved …

The Thai Journal of Veterinary Medicine

This study aimed to determine the optimal concentration of mulberry leaf powder (MLP) supplementation and to evaluate the impact of different seasons on the growth performance, carcass characteristics, and blood lipid levels of Pradu-Hang-Dam chickens. One-week-old chickens were assigned to three groups: a control group (without MLP) and two groups receiving diets supplemented with 0.5% and 1.5% MLP, respectively, over a 10-week period. The results indicated that during the cool season, the control group exhibited the highest feed intake, average daily gain, and superior carcass characteristics (P < 0.05). In the rainy season, chickens supplemented with 1.5% MLP achieved the highest feed intake, while those supplemented with 0.5% MLP showed the highest average daily gain and the lowest feed conversion ratio (P < 0.05). Furthermore, the 1.5% MLP group demonstrated superior carcass characteristics compared to the control group during the rainy season (P < 0.05). Analysis of blood lipid metabolism revealed that the group supplemented with 0.5% MLP during the cool season had the lowest levels of triglycerides, cholesterol, and high-density lipoprotein. In conclusion, the cool season is the most favorable for raising Pradu-Hang-Dam chickens in Thailand. Additionally, supplementing diets with at least 0.5% MLP during the rainy season can improve growth performance, carcass characteristics, and blood parameters.

Investigating The Expression Of C-Myc And Birc5 In Trail And Pbox-15 Treated Metastatic Prostate Cancer Cells, Corinne Kai Leng Chew, Hannah O'Toole, Daniela M. Zisterer, Seema M. Nathwani, Jade K. Pollock

SURE Journal: Science Undergraduate Research Experience Journal

Purpose Metastatic prostate cancer is associated with poor survival rate and limited treatment options. Overexpression of c-Myc and BIRC5 has been reported in prostate cancer cells which contribute to the development of the tumour environment. The specific tumour receptor mechanism of the death ligand TRAIL (tumour necrosis factor related apoptosis inducing ligand) has attracted remarkable therapeutic interest. However, many cancer cells are resistant to TRAIL monotherapy. A novel microtubule-targeting agent, PBOX-15 is known to exhibit anti-tumour activity in cancer cell lines including those with multi-drug resistance. Previous studies demonstrated that PBOX-15 is capable in sensitising cancer cells to TRAIL-mediated cell …

Association Between Body Mass Index, Abdominal Obesity And Menopause-Related Symptoms In Postmenopausal Women, Brianna A. Rice, Patricia Heavey

SURE Journal: Science Undergraduate Research Experience Journal

Abstract: Existing research demonstrates a lack of data on the relationship between body mass index (BMI) and menopause-related symptoms in postmenopausal women, particularly in Ireland. This study aimed to determine whether there is an association between BMI, general abdominal obesity and menopause-related symptoms in postmenopausal women. This should help bridge the data gap regarding postmenopausal women living in Ireland and their symptoms. Introduction: Menopause is defined as the permanent cessation of a woman's menstrual cycle. This is caused by a reduction of the secretion of oestrogen and progesterone, leading to reduced ovarian function. These changes have been attributed …

Reframing The Management Of Irritable Bowel Syndrome: Investigating The Efficacy Of A Modified Low Fodmap Diet Approach On Symptom Response, Tara Howley, Lorraine Cooney, Suzanne L. Doyle

SURE Journal: Science Undergraduate Research Experience Journal

Background/ Objectives: Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction with a multi-faceted pathogenesis. A diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs), known as a low FODMAP diet (LFD), is an effective management option for many, however, it is complex, costly, and restrictive. A milder, modified low FODMAP diet (MLFD) is one suggested alternative, however, data on this approach is lacking. This study aimed to explore the efficacy of a MLFD versus a LFD on symptom improvement in IBS.

Subjects/ Methods: Routine clinical data collected on individuals with a Rome IV IBS diagnosis between August …

Proof Of Causation In A Private Action For Acid Rain Damage, Patrick J. Scully

Maine Law Review

The acid rain problem has become one of the major environmental issues of our day. Each new report on the subject is more disturbing than the last, documenting serious and often irreversible effects of acid rain on lakes and streams, fish and other aquatic life, forests, soils, buildings, and even human health. Present federal legislation is inadequate to deal with acid rain effectively. Proposed legislation could help ameliorate the problem, but even if adopted the effects of such proposals will not be felt until early in the next century. Furthermore, the current administration, particularly the Environmental Protection Agency (EPA), has …

Identification Of Conserved Eukaryotic Gene Products In Novel Mycobacteriophage, Brandon Mar, Jade Coxon, Lily Esterline, Sydney Clifford, Gabriella Burke, Mallory Motz, Alaina Gartner, Kioni Bush, James Lin, Lizzie Adams, Sophia Palant

The Journal of Purdue Undergraduate Research

Bacteriophage, a type of virus that infects bacteria, was discovered 100 years ago, initially isolated with a plaque assay in the 1940s. A mycobacteriophage is a subtype of bacteriophage that specifically infects mycobacteria. Since the introduction of DNA technologies and efforts to identify a plethora of bacteriophages, over 10,000 bacteriophages have been identified with 1,500 sequenced. Bacteriophage discovery has aided in genetic editing techniques, the development of synthetic biology tools, and disease treatment. However, to be able to expand on these capabilities, there is a need to identify more bacteriophages and sequence the genomes of these viruses, as they outnumber …

Prairies typically contain deep-rooted grasses, while agricultural lands contain shallow-rooted row crops. Root depth is considered a major control on …

And You Don't Seem To Understand: Disanalogies Between Artificial And Biological Consciousness, Derek Freeman

The Journal of Purdue Undergraduate Research

This paper posits a new way of attempting to formulate theories of machine consciousness. At present, inquiry revolves around formulating criteria that could be applied to machines to determine if they possess human-like consciousness. The paper demonstrates that efforts so far have not been fruitful, instead finding that present methods of inquiry are destined to result in an impasse between those who support the notion of machine consciousness and those who oppose it. Consequently, the paper questions the assumption that human and machine consciousness must resemble each other. It explores a different approach, one that rejects the idea that the …
