KLF9 and non-small cell lung carcinoma: KLF9 functions via directly regulating various microRNAs that influence tumor behavior, including miR-141, miR-660-5p, miR-625-3p and miR-889, which promote malignancy by targeting KLF9, suggesting that KLF9 could serve as a potential therapeutic target in NSCLC management (33–36).
