Project description:FBXL6 is frequently over-expressed in human hepatocellular carcinoma (HCC). However, it is still unknown the underlying mechanisms by which FBXL6 promotes HCC. In this study, we compared ubiquitinated protein profiles among a panel of liver tissue samples (including HCC, adjacent tissues and normal tissues) from Fbxl6LSL-fl/+; Alb-cre mice and Alb-cre mice by proteomics and ubiquitomics analysis. There are many proteins with ubiquitination in FBXL6 overexpressed HCC, suggesting ubiquitination may play a critical role in FBXL6-mediated HCC.

Project description:Integrin alpha 6 (ITGA6) forms integrin receptors with either integrin β1 (ITGB1) or integrin beta 4 (ITGB4). To study its expression and regulatory functions in hepatocellular carcinoma (HCC) progression, whole transcriptome RNA sequencing in paired HCC tumor and adjacent non-tumor liver tissue samples from ten local Hispanic patients was performed. The average expression of ITGA6 was found increased by over 3.5-fold in HCC tumor tissues in comparison with their adjacent non-tumor tissues. The study indicates integrin alpha6-beta4 complex as a potential therapeutic target for treating patients in HCC.
Project description:HLA class I ligandome dataset obtained from hepatocellular carcinoma (HCC) as well as corresponding adjacent benign liver tissue (n=16) characterizing respective HLA immunoprecipitates. Additionally, from a subset of the mentioned HCC/ adjacent benign liver samples datasets gained from shotgun protein identification, comprising HCC as well as adjacent benign liver tissue (n=7) are provided. Further, for one patient shotgun protein identification was also performed in serum (blood) samples obtained after HCC recurrence.
