knockdown of the expression of circMRPS35 in Huh-7 and HCC-LM3 cells suppressed their proliferation, migration, invasion, clone formation, and cell cycle in vitro, and it suppressed tumor growth in vivo as well. Mechanically, circMRPS35 sponged microRNA-148a-3p (miR-148a), regulating the expression of Syntaxin 3 (STX3), which modulated the ubiquitination and degradation of phosphatase and tensin homolog (PTEN).
circMRPS35 promotes malignant progression and cisplatin resistance in hepatocellular carcinoma.
