Project description:Gene-expression profiles of formalin-fixed, paraffin-embedded human hepatocellular carcinoma tissues obtained at the time of surgical resection. Gene-expression profiling was performed using formalin-fixed, paraffin-embedded hepatocellular carcinoma tissues obtained at the time of surgical resection.
Project description:Hepatocellular carcinoma (HCC) in young subjects is rare but more devastating. We hypothesize that genes and etiological pathways are unique to young HCC (yHCC; ≤40 years old at diagnosis) patients. We therefore compared the gene expression profiles between yHCCs and HCCs from elderly patients.
Project description:To demonstrate CD133+CD44+ and CD133+CD44- subpopulations of hepatocellular carcinoma as distinct subgroups, we have employed whole genome microarray expression profiling as a discovery platform to reveal the gene profiles of different subgroups and identify genes responsible for the enhanced metastatic potentials of CD133+CD44+ tumor cells. CD133+CD44+ and CD133+CD44- tumor cells were isolated from three human metastatic hepatocellular carcinoma specimens. A 76-gene consensus signature was identified that distinguished between CD133+CD44+ and CD133+CD44- subgroups. CD133+CD44+ and CD133+CD44- subgroups from different patients were well clustered as two distinct classes according to this signature, and many genes in this signature were reported involved in tumor metastasis. Expression of four genes (CCL4, DKK3, CCR5 and MMP12) from this signature was confirmed in another three metastatic HCC specimens by real-time PCR. CD133+CD44+ and CD133+CD44- subpopulations of hepatocellular carcinoma were isolated from three metastatic hepatocellular carcinoma specimens by flow cytometry. A total of 30K to 50K cells for each subgroup was obtained for each microarray.

Project description:To investigate the significance of CD44+ hepatocellular carcinoma (HCC) HuH7 cells, gene expression profiles of CD44-positive HuH7, CD44-negative HuH7, and human nomal hepatocyes were analyzed. Results provide the insight into the significance of CD44-positive HCC cells as the liver CSCs.
Project description:Sulfatide significantly promoted hepatocellular carcinoma cells survival, proliferation and angiogenesis. To understand the molecular mechanisms of sulfatide, the transcriptional profiles of lncRNAs in human hepatocellular carcinoma cells SMMC-7721 was investigated with ArrayStar lncRNA microarray with sulfatide treatment. Galactose-cerebroside treatment served as the control.
