Na,K-ATPase is essential for the regulation of cytoplasmic Na+ and K+ levels in lens cells. Insufficient Na,K-ATPase activity is associated with cataract formation. Based on earlier studies in which Src-tyrosine kinase inhibitors were found to...
Exocytosis of intracellular granules is critical for conversion of inactive, circulating neutrophils to fully activated cells. The p38 MAPK pathway plays a central role in neutrophil exocytosis, although its mechanism of action is unknown. We used...
The role of the active site tyrosine residue in the Co-C5' bond activation in the
context of adenosylcobalamin-dependent mutases has been computationally
investigated. The density functional, complete active space self-consistent field
and quantum...
Parkinson's disease--Treatment; Stem cells--Therapeutic use
Parkinson's disease (PD) is a hypokinetic movement disorder resulting from the
progressive neurodegeneration of the dopaminergic nigrostriatal system in the brain and
the resulting imbalance between dopamine and acetylcholine in the basal ganglia...
Pancreatic beta cells are extremely vulnerable to destruction by Reactive Oxygen Species (ROS). In type 1 diabetes and islet transplantation ROS are thought to be involved in the loss of beta cells. To test the role of antioxidant in islet...
20S proteasome, essential component of protein degradation mechanism, is important to maintain homeostasis. Its malfunctions have been associated with several pathological conditions. This study presents an extensive study of murine cardiac 20S...
Human adult olfactory epithelium contains neural progenitors (hONPs) which replace damaged cellular components throughout life. Methods to isolate and expand the hONPs have been developed in our laboratory. In response to morphogens, the hONPs...
Ischemic heart disease is the leading cause of mortality and morbidity in Western societies. Thus, understanding the molecular mechanisms to reduce myocardial ischemia and limit infarction size are of great importance. Ample evidence has shown that...
Hepatitis C virus--Research; Interferon--Therapeutic use; Adenosylmethionine
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease in the United States and is a huge burden on the US healthcare system. The FDA-approved traditional standard of care for HCV is pegylated interferon-alpha (lFNα) combined...
The chaperone heat shock protein 90 (Hsp90) regulates physiologically and
pathological cellular processes, by binding and stabilizing kinases involved in basal
cellular functions and in cellular responses to stress, respectively. I hypothesize...
Alcoholic liver disease (ALD) is a serious concern for the world's population. It is one of the leading causes of death and is also a huge economic burden. The biochemical mechanisms responsible for ALD are incompletely understood, therefore there...
Mishaps in prenatal development can influence mammary gland development
and, ultimately, affect susceptibility to factors that cause breast cancer. This research was
based on the underlying hypothesis that maternal dietary composition during...
Chlamydia trachomatis is an obligate intracellular pathogen that utilizes a type III secretion system to enter mammalian cells and establish an intracellular niche. TARP, the translocated actin recruitment protein, is a chlamydial invasion protein...
Reperfusion of the ischemic lung causes pulmonary arteriolar vasoconstriction and reduces alveolar perfusion. Lung ischemia-reperfusion (IR) injury leads to platelet and leukocyte activation which could contribute to decreased alveolar perfusion...
Collateral sprouting (CS) occurs when uninjured axons respond to denervated tissue surrounding the axon by growing branches of the axon to reinnervate the denervated zone. This process is signaled by factors released by the denervated tissue. Nerve...
The current status of our knowledge of synaptic plasticity comes largely from studies of the hippocampus and the context of learning and memory. We remain largely ignorant of plasticity in other neural systems and contexts. The molecular basis of...
Heart--Hypertrophy; Hydrogen sulfide--Therapeutic use
Background: Although matrix metalloproteinase (MMPs) and tissue inhibitor of metalloproteinase (TIMPs) play a vital role in tumor angiogenesis and TIMP-3 causes apoptosis, their role in cardiac angiogenesis is unknown. Interestingly, a disruption...
Premenopausal women have fewer and less severe strokes when compared to postmenopausal females and aged matched males. The most obvious factor that could account for the observed difference is the physiological activity of Estrogen. Numerous...
Myocardial infarction; Glucose--Metabolism; Mitochondrial DNA
Heart failure is a leading cause of morbidity and mortality in the USA. During the development of heart failure, many cardiac parameters change at the same time including fuel metabolism, oxidative stress and mitochondrial function. Each of these...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
