Placenta-Related PEG10 Inhibits mRNA Decay to Promote Glucose Metabolism and Tumor Progression in Hepatocellular Carcinoma.

Placenta-related PEG10 promotes hepatocellular carcinoma progression by inhibiting mRNA decay and enhancing glucose metabolism, with overexpression linked to poor prognosis.

• Why it matters: Understanding how embryonic and placental genes are reactivated in tumors can reveal new targets for cancer therapy, especially in aggressive cancers like HCC.
• What they did: The study screened placental-specific genes in HCC, identified PEG10 overexpression, and used mouse models and molecular techniques to explore its role in tumor growth and metabolism.
• The result: PEG10 stabilizes glucose transporter and enzyme mRNAs, boosting glycolysis and tumor growth; retinoic acid and sorafenib can inhibit this pathway, offering potential therapeutic strategies.
