Insulin In Combination With N-Acetylcysteine Protects Hypoxia-Induced Toxicity In 661w Cells, Lili M. Guerra, Laura Valdez, Benxu Cheng, Andrew Tsin

Research Colloquium

Background: Proliferative diabetic retinopathy (PDR) is the leading cause of blindness among working-age adults. Photoreceptors are the most numerous and metabolically demanding cells in the retina thus oxygen is essential for retinal function. It has been reported that photoreceptors found in rat retina are specifically vulnerable to hypoxia. Hypoxia-induced metabolic stress leads to photoreceptor atrophy and retinopathy. Furthermore, photoreceptor cell death is known to occur mainly through apoptosis. However, the protection of hypoxia-induced-cytotoxicity in cone photoreceptor cells has not been investigated extensively. The aim of this study was to determine whether co-treatment of insulin and the N-Acetyl-L-Cysteine (NAC) (a free …


Molecular Event In Hrp Apoptosis, Laura Valdez Oct 2023

Molecular Event In Hrp Apoptosis, Laura Valdez

Research Colloquium

Background: Human retinal pericytes (HRP) are contractile cells providing support for endothelial cells of capillaries, essential in the regulation of retinal vasculature. Early stages of DR are characterized by the loss of HRP, leading to angiogenesis. Our preliminary studies identified monocyte-derived macrophages secrete TGF-β1, inducing the expression and secretion of a TGFβ1-Induced, pro-apoptotic BIGH3 protein leading to apoptosis of HRP. Based on a preliminary study in renal cells (unpublished data), CTP with an RGD domain is released from BIGH3 by proteolysis leading to renal cell apoptosis. In the present study, we employed Western Blots to determine if a similar molecular …


Irbp In Diabetic Retinopathy – Cell Culture & Ophthalmic Pathology Studies, Laura Valdez Oct 2023

Irbp In Diabetic Retinopathy – Cell Culture & Ophthalmic Pathology Studies, Laura Valdez

Research Colloquium

Background: Interphotoreceptor-Retinoid-Binding-Protein (IRBP) is restricted to the subretinal space by the external limiting membrane and RPE zonulae occludens. Its expression is reduced in diabetic retinopathy (DR) and increased expression is protective. Hypoxia decreases viable conelike photoreceptors (661W) but increased VEGF, suggesting a role of photoreceptors in proliferative DR (PDR) (Rodriguez et al, Arch Clin Exp. Ophthal 3:23,2021). Here, we investigated the effects of high glucose and VEGF on IRBP expression by 661W and rod-like Y79 cells and distribution of IRBP and albumin in human globes with PDR and NPDR.

Methods:  661W and Y79 cells were cultured in DMEM or RPMI …

Penile Calciphylaxis In An End Stage Renal Disease Patient., Juan Enrique Garcia Lopez, Alain Velazquez Blanco, Aileen Aguilar, Sareena Siyas, Daniel Ibarias Paz, Mays Abdulazeez, Jesus Garza-Tamez, Desmond Adamu

Research Colloquium

Background: Penile Calciphylaxis occurs in about 1–4% of hemodialysis patients worldwide. Associated mortality rates are very high, and hyperparathyroidism is the second most frequently associated disorder. Addressing the resulting metabolic imbalance, and surgical intervention guided by findings of radiological studies may improve quality of life. The pathogenesis is thought to be mediated by vascular smooth muscle cells which differentiate into osteoblast-like cells. Decrease in vascular calcification inhibitory proteins fetuin-A and matrix Gla is found in patients on dialysis causing systemic medial calcification of arterioles, leading to epidermal ischemia, tissue infarction, and ulceration.

Case presentation: 47-year-old male with history of coronary …

Dissecting The Daily Feeding Pattern: Peripheral Clock/Cycle Generate The Feeding/Fasting Episodes And Neuronal Molecular Clocks Synchronize Them, Akiko Maruko, Koichi M Iijima, Kanae Ando Oct 2023

Dissecting The Daily Feeding Pattern: Peripheral Clock/Cycle Generate The Feeding/Fasting Episodes And Neuronal Molecular Clocks Synchronize Them, Akiko Maruko, Koichi M Iijima, Kanae Ando

Department of Neuroscience Faculty Papers

A 24-h rhythm of feeding behavior, or synchronized feeding/fasting episodes during the day, is crucial for survival. Internal clocks and light input regulate rhythmic behaviors, but how they generate feeding rhythms is not fully understood. Here we aimed to dissect the molecular pathways that generate daily feeding patterns. By measuring the semidiurnal amount of food ingested by single flies, we demonstrate that the generation of feeding rhythms under light:dark conditions requires quasimodo (qsm) but not molecular clocks. Under constant darkness, rhythmic feeding patterns consist of two components: CLOCK (CLK) in digestive/metabolic tissues generating feeding/fasting episodes, and the …

This position stand is intended to provide a scientific foundation to athletes, dietitians, trainers, and other practitioners as to the benefits of supplemental EAA in both healthy and resistant (aging/clinical) populations. EAAs are crucial components of protein intake in humans, as the body cannot synthesize them. The daily recommended intake (DRI) for protein was established to prevent deficiencies due to inadequate EAA consumption. The following conclusions …


Podcasts As A Form Of Social Support For Individuals With Chronic Illness, Kate Pederson, Melanie Finney Oct 2023

Podcasts As A Form Of Social Support For Individuals With Chronic Illness, Kate Pederson, Melanie Finney

Annual Student Research Poster Session

Chronic illness frequently decreases individuals’ abilities to receive social support. 105 listeners of health-related podcasts completed online closed and open-ended surveys. Results indicate 97% of respondents experience social isolation because of their illness, and 90% report listening to podcasts help them feel less isolated. Additionally, condition-specific podcasts allow people to gain relevant information about managing health challenges, as well as feel part of a community of people who understand them. Finally, results suggest parasocial relationships with hosts of the podcasts correlate positively with informational support, which subsequently is correlated positively with perceived emotional support.

Generalization Of Procedural Motor Sequence Learning After A Single Practice Trial, B P Johnson, I Iturrate, R Y Fakhreddine, M Bönstrup, E R Buch, E M Robertson, L G Cohen

2020-Current year OA Pubs

When humans begin learning new motor skills, they typically display early rapid performance improvements. It is not well understood how knowledge acquired during this early skill learning period generalizes to new, related skills. Here, we addressed this question by investigating factors influencing generalization of early learning from a skill A to a different, but related skill B. Early skill generalization was tested over four experiments (N = 2095). Subjects successively learned two related motor sequence skills (skills A and B) over different practice schedules. Skill A and B sequences shared ordinal (i.e., matching keypress locations), transitional (i.e., ordered keypress pairs), …

Faculty, Staff and Student Publications

Platelets are generated by specialized cells called megakaryocytes (MKs). However, MK's origin and platelet release mode have remained incompletely understood. Here, we established direct visualization of embryonic thrombopoiesis in vivo by combining multiphoton intravital microscopy (MP-IVM) with a fluorescence switch reporter mouse model under control of the platelet factor 4 promoter (Pf4CreRosa26mTmG). Using this microscopy tool, we discovered that fetal liver MKs provide higher thrombopoietic activity than yolk sac MKs. Mechanistically, fetal platelets were released from MKs either by membrane buds or the formation of proplatelets, with the former constituting the key process. In E14.5 c-Myb-deficient …

Inflammatory breast cancer (IBC) presents as rapid-onset swelling and breast skin changes caused by tumor emboli in the breast and breast skin lymphatics. IBC has been linked with obesity and duration of breastfeeding, but how these factors affect IBC tumor progression is not clear. We modeled the simultaneous effects of diet and weaning in mice on in vivo lymphatic function; on IBC tumor growth; and on aspects of the mammary gland microenvironment before and after IBC (SUM149) xenograft inoculation. We hypothesized that weaning status and diet would have synergistic effects on lymphatic function and the breast microenvironment to enhance IBC …

School of Integrative Biological & Chemical Sciences Faculty Publications

Mosquitoes have profoundly affected human history and continue to threaten human health through the transmission of a diverse array of pathogens. The phylogeny of mosquitoes has remained poorly characterized due to difficulty in taxonomic sampling and limited availability of genomic data beyond the most important vector species. Here, we used phylogenomic analysis of 709 single copy ortholog groups from 256 mosquito species to produce a strongly supported phylogeny that resolves the position of the major disease vector species and the major mosquito lineages. Our analyses support an origin of mosquitoes in the early Triassic (217 MYA [highest posterior density region: …

Autoimmune Encephalitis Of Unknown Etiology, Elizabeth Cook, Giselle Ricoy

Research Colloquium

Encephalitis is the inflammation of the brain which can come about through various etiologies. Autoimmune encephalitis is a rare form that is most common among women and children. The clinical presentation can vary between patients with a constellation of symptoms including deficits in memory, cognition, seizures, abnormal movement, psychosis, and coma. Because of the variation in clinical presentation and the lack of specificity in imaging and laboratory findings, diagnosis and intervention are often delayed for months to years. These delays in diagnosis can have long term ramifications on patients especially pediatric patients whose neural pathways are still developing. In pediatric …
