Acrolein--Toxicology; Stem cells--Effect of pollution on
Acrolein is a common pollutant present in ambient air, automobile exhaust, and tobacco smoke. Previous studies show that exposure to acrolein increases cardiovascular disease risk. To determine whether acrolein affect cardiovascular regeneration,...
Background. Progression of alcoholic liver disease (ALD) is associated with an increase in fibrin extracellular matrix (ECM) and inflammation. Previous studies have shown that this accumulation of fibrin in ALD is mediated by impaired fibrinolysis....
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...
Cardiology--Research--Methodology; Microfluidics--Equipment and supplies
Cardiovascular disease (CVD) is the leading cause of death in the United States and accounts for nearly 1,372,000 deaths each year. In addition, ~81 million Americans suffer from some form of CVD. Understanding the molecular basis of various...
Chapter I . Seven novel head-to-tail cyclic pentapeptides and pseudopentapeptides containing the arginine-glycine-aspartic acid (RGD) tripeptide motif were synthesized. All of the peptides were constructed using solid phase peptide synthesis....
Circulating nucleated cell populations found in whole blood, including both white blood cells (leukocytes) and endothelial cells, provide an ideal platform for studies seeking to understand the disease processes for development of drugs and...
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...
T cells; Disease susceptibility; Lupus; Sex factors in disease
Females are more susceptible to autoimmune disease than males. In several mouse models of disease, castration of males exacerbates disease while androgen treatment ameliorates disease. These data suggest hormones can have an influence on disease...
Integrins are major receptors for cell adhesion to the extracellular matrix, and play key roles in various cellular processes including adhesion, migration, proliferation and survival. Apart from developmental and physiological events, integrins...
Interactions between chemokines and their receptors are involved in organ- specific homing and propagation of metastatic breast cancer (BrCa) cells. BrCa cells express higher levels of CXCR4 and CXCR7 mRNA and cell surface protein, than normal...
Nanostructured materials; Nanotubes; Nanoparticles; Drug delivery systems; Diagnostic Imaging
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
Periodontitis--Age factors; Natural immunity; Age factors in disease
Periodontal disease arises from excessive host inflammatory responses to the tooth-associated microbial biofilm, known as dental plaque. Severity ranges from superficial inflammation of the gingivae (gingivitis) to extensive destruction of...
Pituitary tumor transforming gene ( PTTG ), also known as securing, is a novel oncogene that is expressed at high levels in most of the tumors analyzed to date. Overexpression of PTTG in mouse fibroblast(NIH 3T3) cells increases cell proliferation,...
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...
Colon (Anatomy)--Cancer--Genetic aspects; Cancer cells--Mathematical models
Research over the past twenty five years has led to the development of the hypothesis that colorectal cancer is caused by the accumulation of mutations in tumor suppressor genes and proto-oncogenes. The last ten years has also revealed that the...
Nerves--Regeneration; Spinal cord--Wounds and injuries--Treatment
These studies set out to identify strategies to rescue and repair the adult nervous system. First, we investigated the role of ciliary neurotrophic factor (CNTF) in 5HT1A receptor-induced neurogenesis in the rodent brain. Systemic treatment with an...
