Project description:In Asia, oral cancer (OC) and oral submucous fibrosis (OSF) constitute major health problems linked to use of betel quid. This work performed CGH genome-wide analysis of OC (12 from India, 12 from Sri Lanka) and OSF (6 from India) cases with normal controls.
Project description:Cell therapy shows great promise as an alternative therapy for the cirrhotic liver. We have previously developed an approach for efficient expansion of both murine and human hepatocyte-derived liver progenitor-like cells (HepLPCs) in vitro without genetic modification. The current study aimed to apply HepLPCs to treatment of liver cirrhosis. The effects of allogeneic HepLPCs transplantation were studied in rat models of liver cirrhosis induced by carbon tetrachloride (CCl4) . Liver tissues were collected and analyzed by RNA sequencing array to analyze changes in histology or gene expression patterns. Transplantation of HepLPCs reduced active fibrogenesis and net fibrosis in model of liver cirrhosis. Apoptosis of hepatic stellate cells (HSCs) was observed in vivo after HepLPCs treatment.
Project description:Non-alcoholic fatty liver disease (NAFLD) affects 25% of the population and can progress to cirrhosis, where treatment options are limited. As the liver secrets most of the blood plasma proteins, its diseases should affect the plasma proteome. Plasma Proteome Profiling of 48 patients with cirrhosis or NAFLD, revealed eight significantly changing (ALDOB, APOM, LGALS3BP, PIGR, VTN, IGHD, FCGBP and AFM), two of which are already linked to liver disease. Polymeric immunoglobulin receptor (PIGR) was significantly elevated in both cohorts with a 2.7-fold expression change in NAFLD and 4-fold change in cirrhosis and was further validated in mouse models. Furthermore, a global correlation map of clinical and proteomic data strongly associated DPP4, ANPEP, TGFBI, PIGR, and APOE to NAFLD and cirrhosis. The prominent diabetic drug target DPP4 is an aminopeptidase like ANPEP, ENPEP and LAP3, which all upregulated in the human or mouse data. Furthermore, ANPEP and TGFBI have potential roles in extracellular matrix remodeling in fibrosis. Thus, Plasma Proteome Profiling can identify potential biomarkers and drug targets in liver disease.

As the liver secrets most of the blood plasma proteins its diseases should affect the plasma proteome. Plasma proteome profiling on 48 patients with cirrhosis or NAFLD with normal glucose tolerance or diabetes, revealed 8 significantly changing (ALDOB, APOM, LGALS3BP, PIGR, VTN, IGHD, FCGBP and AFM), two of which are already linked to liver disease. Polymeric immunoglobulin receptor (PIGR) was significantly elevated in both cohorts with a 2.7-fold expression change in NAFLD and 4-fold change in cirrhosis and was further validated in mouse models. Furthermore, a global correlation map of clinical and proteomic data strongly associated DPP4, ANPEP, TGFBI, PIGR, and APOE to NAFLD and cirrhosis. DPP4 is a known drug target in diabetes. ANPEP and TGFBI are of interest because of their potential role in extracellular matrix remodeling in fibrosis.
Project description:Gene profiling of hepatocytes in early and advanced cirrhotic Rats Two-condition experiment, Advanced cirrhosis vs Control liver, Advanced cirrhosis vs Early cirrhosis. Biological replicates: 5 Advanced cirrhosis, 5 Early cirrhosis, 5 control liver. Each hepatocyte was isolated independently. One replicate per array.
Project description:We genotyped 45 new samples from 4 populations of Northwest India and combined it with previously published data to characterize the population structure of modern Northwest Indian populations in the context of their geographic neighbors across South Asia and West Eurasia.
