Two of every three persons living with dementia reside in low- and middle-income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high-income countries (HICs), with dementia research predominantly focusing on HICs. This imbalance necessitates LMIC-focused research to ensure that characterization of dementia accurately reflects the involvement and specificities of diverse populations. Development of effective preventive, diagnostic, and therapeutic approaches for dementia in LMICs requires targeted, personalized, and harmonized efforts. Our article represents timely discussions at the 2022 Symposium on Dementia and Brain Aging …

Currently, more than 55 million people around the world suffer from dementia, and Alzheimer’s Disease and Related Dementias (ADRD) accounts for nearly 60–70% of all those cases. The spread of Alzheimer’s Disease (AD) pathology and progressive neurodegeneration in the hippocampus and cerebral cortex is strongly correlated with cognitive decline in AD patients; however, the molecular underpinning of ADRD’s causality is still unclear. Studies of postmortem AD brains and animal models of AD suggest that elevated endoplasmic reticulum (ER) stress may have a role in ADRD pathology through altered neurocellular homeostasis in brain regions associated with learning and memory. To study …

Statistical Genetic Approaches To Investigate Genotype-By-Environment Interaction: Review And Novel Extension Of Models, Vincent P. Diego, Eron G. Manusov, Marcio Almeida, Sandra Laston, David Ortiz, John Blangero, Sarah Williams-Blangero

School of Medicine Publications and Presentations

Statistical genetic models of genotype-by-environment (G×E) interaction can be divided into two general classes, one on G×E interaction in response to dichotomous environments (e.g., sex, disease-affection status, or presence/absence of an exposure) and the other in response to continuous environments (e.g., physical activity, nutritional measurements, or continuous socioeconomic measures). Here we develop a novel model to jointly account for dichotomous and continuous environments. We develop the model in terms of a joint genotype-by-sex (for the dichotomous environment) and genotype-by-social determinants of health (SDoH; for the continuous environment). Using this model, we show how a depression variable, as measured by the …

Although previous studies have examined the signaling pathway involved in melanogenesis through which ultraviolet (UV) or α-melanocyte-stimulating hormones (α-MSH) stimuli act as key inducers to produce melanin at the stratum basal layer of the epidermis, the signaling pathway regulating melanogenesis is still controversial. This study reports that α-MSH, not UVA and UVB, acted as a major stimulus of melanogenesis in B16F10 melanoma cells. Signaling pathway analysis using gene knockdown technology and chemical inhibitors, the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK)/p90 ribosomal S6 kinase 2 (RSK2) played an important role in melanogenesis. Unexpectedly, LY294002, a PI3K inhibitor, increased melanogenesis …

Oma1-Mediated Mitochondrial Dynamics Balance Organellar Homeostasis Upstream Of Cellular Stress Responses, Robert Gilkerson, Harpreet Kaur, Omar Carrillo, Isaiah Ramos

School of Integrative Biological and Chemical Sciences Faculty Publications and Presentations

In response to cellular metabolic and signaling cues, the mitochondrial network employs distinct sets of membrane-shaping factors to dynamically modulate organellar structures through a balance of fission and fusion. While these organellar dynamics mediate mitochondrial structure/function homeostasis, they also directly impact critical cell-wide signaling pathways such as apoptosis, autophagy, and the integrated stress response (ISR). Mitochondrial fission is driven by the recruitment of the cytosolic dynamin-related protein-1 (DRP1), while fusion is carried out by mitofusins 1 and 2 (in the outer membrane) and optic atrophy-1 (OPA1) in the inner membrane. This dynamic balance is highly sensitive to cellular stress; when …

School of Podiatric Medicine Publications and Presentations

Highlights

  • Peripheral artery disease (PAD) is a multi-level disease.

  • PAD diffusely impairs the performance of leg muscles.

  • PAD causes similar irregularities in gait biomechanics regardless of where claudication pain is located in the leg.

Abstract

Background

The most common symptom of peripheral artery disease (PAD) is intermittent claudication that involves the calf, thigh, and/or buttock muscles. How the specific location of this leg pain is related to altered gait, however, is unknown.

Objectives

We hypothesized that because the location of claudication symptoms uniquely affects different leg muscle groups in people with PAD, this would produce distinctive walking patterns.

Methods

Mechanical Engineering Faculty Publications and Presentations

Purpose: The lamina cribrosa (LC) depends on the sclera for support. The support must be provided through the LC insertions. Although a continuous insertion over the whole LC periphery is often assumed, LC insertions are actually discrete locations where LC collagenous beams meet the sclera. We hypothesized that LC insertions vary in number, size, and shape by quadrant and depth.

Methods: Coronal cryosections through the full LCs from six healthy monkey eyes were imaged using instant polarized light microscopy. The images were registered into a stack, on which we manually marked LC insertion outlines, nothing their position in-depth and quadrant …

The Role Of Divergent Noncoding Gene In Triple-Negative Breast Cancer, Barbara Yang, Melina J. Sedano, Shrikanth S. Gadad Mar 2024

The Role Of Divergent Noncoding Gene In Triple-Negative Breast Cancer, Barbara Yang, Melina J. Sedano, Shrikanth S. Gadad

Research Symposium

Breast cancer is the second leading cause of cancer mortality in women after lung cancer. Breast cancer is grouped into different molecular subtypes; triple-negative breast cancer (TNBC) accounts for 20%. TNBC is a highly aggressive histologic subtype; the lack of unique therapeutic targets makes it harder to treat. Recent studies have implicated genes involved in cancers that are transcribed using a process known as divergent transcription. The expression of these genes is tightly regulated; however, many escape regulation and become aberrantly expressed in tumors. Interestingly, our genomic analysis suggests that several of these genes encode noncoding transcripts. Analysis of transcriptome …

The Role Of A Cancer Testis-Antigen In Regulating Tumor Growth And Oncogenic Pathways In Triple-Negative Breast Cancer., Melina J. Sedano, Alana L. Harrison, Victoria Reid, Subramanian Dhandayuthapani, Shrikanth S. Gadad

Research Symposium

Breast cancer is the second leading cause of cancer-related deaths in women, after lung cancer. Unfortunately, it is the primary cause of death among Hispanic women. Approximately 10-20% of breast cancers are classified as basal (triple-negative) subtypes, which are challenging to treat due to the absence of specific targets. Triple-negative breast cancer is a highly aggressive and lethal type of tumor, particularly among Hispanic women, with a poor prognosis compared to other breast cancer subtypes. Therefore, it is crucial to identify new molecules with therapeutic and prognostic values to treat this evolving disease. Multiple studies have demonstrated that X-linked genes …

Role Of Trpv6 In Mitigating Alcohol-Induced Disruption Of Tight Junctions, Barrier Function, And Hepatic Injury, Avtar S. Meena, Radhakrishna K. Rao

Research Symposium

Background: Persistent alcohol consumption is widely recognized as a precursor to alcoholic liver disease. However, the intriguing observation persists that only a minority, approximately 20%, of individuals with alcohol use disorder succumb to this liver ailment. The factors contributing to this variability remain elusive. Studies indicate that individuals with alcoholic liver disease exhibit endotoxemia, with endotoxins primarily originating from colonic microflora. Moreover, these patients manifest disruptions in epithelial tight junctions, leading to compromised barrier function in the gastrointestinal tract. In this context, the transient receptor vanilloid receptor 6 (TRPV6) emerges as a crucial regulator of calcium absorption and transport, particularly …
