Exploration of Potential Genomic Portraits Associated with Intrahepatic Recurrence in Human Hepatocellular Carcinoma.
Summary of "Exploration of Potential Genomic Portraits Associated with Intrahepatic Recurrence in Human Hepatocellular Carcinoma."
BACKGROUND:
Hepatocellular carcinoma (HCC) is a heterogeneous disease with recognized variability in virus infection, genetic features, and clinical outcome. To date, transcriptional profilings of HCC have been used to predict recurrence or survival/prognosis. However, there remains a challenge to identify specific genomic prints associated with HCC recurrence, which could lead to novel therapies or effective treatment. Here we examine the association between biological signals and intrahepatic recurrence using global gene expression profiles and powerful analytical methods. MATERIALS AND
METHODS:
Gene expression profiles were generated in 24 HCC patients with hepatitis B infections (B-type HCC) and 60 HCC patients with hepatitis C infections (C-type HCC). Gene set enrichment analysis (GSEA) was applied to the entire ranked gene lists related to early intrahepatic recurrence, based on "ideal discriminator method."
RESULTS:
GSEA revealed Ribosomal Proteins as a common regulatory pathway in B-type (P < .001) and C-type (P = .003) HCC recurrence. In addition, Proteasome (P < .001) and Pentose Phosphate Pathway (P = .01) were identified as specific pathways in each type of HCC recurrence, respectively.
CONCLUSIONS:
Understanding these biologically common and different mechanisms related to intrahepatic recurrence in B-type and C-type HCC could be useful in the development of new therapeutic strategies in our fight against HCC.

Medical and Biotech [MESH] Definitions
Cholestasis, Intrahepatic
Impairment of bile flow due to injury to the HEPATOCYTES; BILE CANALICULI; or the intrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC).
Neoplasm Recurrence, Local
The local recurrence of a neoplasm following treatment. It arises from microscopic cells of the original neoplasm that have escaped therapeutic intervention and later become clinically visible at the original site.
Genomic Structural Variation
Contiguous large-scale (1000-400,000 basepairs) differences in the genomic DNA between individuals, due to SEQUENCE DELETION; SEQUENCE INSERTION; or SEQUENCE INVERSION.
Liver Cirrhosis, Biliary
FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cirrhosis involves the destruction of small intra-hepatic bile ducts and bile secretion. Secondary biliary cirrhosis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.
Comparative Genomic Hybridization
A method for analyzing and mapping differences in the copy number of specific genes or other large sequences between two sets of chromosomal DNA. It is used to look for large sequence changes such as deletions, duplications, or amplifications within the genomic DNA of an individual (with a tumor for example) or family members or population or between species.
