Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane
Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane
DePaul Discoveries
Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide5,6. It is estimated that roughly 80% of those infected suffer from persistent infection with the virus; this persistence of infection is progressive, and over time can lead to fibrosis, cirrhosis, and hepatocellular carcinoma7. Chronic inflammation and apoptotic deregulation are both hallmarks of chronic HCV infection, and many molecular pathways are initiated in both the innate and adaptive immune responses during infection with this viral pathogen. The aim of this review was to survey some of the major molecular mechanisms responsible for the induction of …
A Protective Role Of Autophagy In A Drosophila Model Of Friedreich's Ataxia (Frda), Luan Wang
A Protective Role Of Autophagy In A Drosophila Model Of Friedreich's Ataxia (Frda), Luan Wang
Wayne State University Dissertations
Friedreich’s ataxia (FRDA) is an inherited autosomal recessive neurodegenerative disease. It affects 1 in every 50,000 people in central Europe and North America. FRDA is caused by deficiency of Frataxin, an essential mitochondrial iron chaperone protein, and the associated oxidative stress damages. Autophagy, a housekeeping process responsible for the bulk degradation and turnover of long half-life proteins and organelles, is featured by the formation of double-membrane vacuoles and lysosomal degradation. Previous researches indicate that Danon’s disease, the inherited neural disorder disease that shares similar symptoms with FRDA, is due to the malfunction of autophagy. Based on this, we raise the …
Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai
Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai
Theses and Dissertations--Toxicology and Cancer Biology
This work describes the fascinating interplay between two tumor suppressors Prostate apoptosis response-4 (Par-4) and p53. The guardian of the genome, p53, is frequently mutated in human cancers, and may contribute to therapeutic resistance. However, p53 is intact and functional in normal tissues, and we observed that specific activation of p53 in normal fibroblasts could induce apoptosis selectively in p53-deficient cancer cells. This paracrine apoptotic effect was executed by Par-4 secreted in response to p53 activation. Accordingly, activation of p53 in wild-type mice, but not in p53-/- or Par-4-/- mice, caused systemic elevation of Par-4 that induced apoptosis …
Rna Aptamers For Molecular Chaperones Hsp27 And Hsp90, Sathishkumar Kumar Munusamy
Rna Aptamers For Molecular Chaperones Hsp27 And Hsp90, Sathishkumar Kumar Munusamy
Legacy Theses & Dissertations (2009 - 2024)
Hsp90 and Hsp27 are members of the heat shock protein family of chaperones that perform multiple roles in cellular maintenance through protein folding and inhibition of apoptosis. They are abundantly expressed in cells and are over-expressed during conditions of stress. Hsp90 requires ATP for its chaperone function while Hsp27 self-associates into higher order oligomers enclosing its substrate. Their ability to interact with other proteins or with themselves lies at the heart of their mechanisms. The specific consequences of each of their interactions on global cellular health have not yet been fully discovered. The sheer diversity of proteins that interact with …
