Multivariate analyses revealed that tumor size and HINT2 expression are risk factors for Hepatocellular carcinoma recurrence. HINT2 is down-regulated in Hepatocellular carcinoma, and low HINT2 expression predicts earlier tumor recurrence. HINT2 expression may serve as a prognostic indicator of recurrence in Hepatocellular carcinoma.

Title: The histidine triad nucleotide-binding protein 2 (HINT-2) positively regulates hepatocellular energy metabolism.
Authors deduced that HINT2 triggers apoptosis in pancreatic cancer cells by regulating mitochondrial Ca(2+) influx through the mitochondrial calcium uniporter (MCU). Authors found that HINT2 can sensitize BxPC-3 and L3.6pl cells to gemcitabine-induced apoptosis and that gemcitabine up-regulates HINT2 expression.

HINT2 downregulation depended on hypoxia inducible factor (HIF)-2alpha-mediated transcriptional activation of zinc finger E-box-binding homeobox 1 (ZEB1). These results suggest that HINT2 downregulation promotes HIF-2alpha expression, which induces EMT and enhances CRC cell migration and invasion.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
