IL6ST

Overview

IL6ST encodes gp130 (glycoprotein 130), the shared signal transducer subunit of the IL-6 family cytokine receptors. gp130 mediates signaling for IL-6, IL-11, oncostatin M, and other cytokines through JAK/STAT3 activation. In HCC, IL6ST is listed as a recurrently mutated gene in the mutational landscape.

Alterations observed in the corpus

  • IL6ST is listed among recurrently mutated genes in the HCC WES landscape (n=1,289), part of the broader mutational context characterizing the JAK/STAT signaling axis. PMID:24798001
  • IL6ST mutations found exclusively in HCC of unknown etiology and mostly restricted to hepatocellular adenomas in non-fibrotic settings; IL6/JAK/STAT pathway altered in 9% of the 243-case European HCC cohort PMID:25822088

Cancer types (linked)

  • HCC (hepatocellular carcinoma): Recurrently mutated in HCC cohorts; functional implications for IL-6/JAK/STAT3 signaling in liver cancer. PMID:24798001

Co-occurrence and mutual exclusivity

  • Co-listed with JAK1 and other signaling pathway genes in the HCC mutational landscape. PMID:24798001

Therapeutic relevance

  • No direct therapeutic targeting of IL6ST reported in this corpus for HCC; JAK inhibitors targeting downstream signaling are under general investigation.

Open questions

  • Frequency and functional impact of IL6ST mutations in HCC require dedicated characterization; the paper lists it among recurrently mutated genes without reporting specific mutation frequencies.
