Project description:Genome-wide miRNA expression profiles of 100 primary and matched non-malignant tissues of HCC patients from a Singapore patient cohort. HCC is a hetergenous disease and it is important to understand the underlying molecular mechanisms. Here, we studied the role of microRNAs in HCC by integrating microRNA and gene expression profiles of HCC patients. Profiling of 100 primary and adjacent non-malignant HCC tissue samples on mirXplore two-color miRNA expression microarray. All tissues were collected with approvals from the National Cancer Centre, Singapore; the Research Ethics Review Committee; and signed patient informed consent.

Project description: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 3 local Hispanic patients was performed.
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:Here we aimed to develop a new molecular prognostic stratification system for hepatocellular carcinoma (HCC) patients after liver resection based on common prognostic factors for primary tumors (PTs) and adjacent non-tumor tissues (ANTTs). We studied global mRNA expression profiles from 115 PT tissue samples and 52 ANTT samples derived from 115 HCC patients. Methods for the study included gene expression analysis, Functional Annotation/Gene Ontology analysis and unsupervised survival prognosis approach based on Cox hazards prognosis model. This study provides a practical prognostic system for reliable identification of the high-risk HCC patients subgroup with clearly described deregulated molecular machinery in both PTs and ANTTs.
