RAC1 and gastric cancer: Yu et al. demonstrated that MALAT1 functions as a competing endogenous RNA, modulating Rac1 expression by sequestering miR-101b in liver fibrosis, and lncRNA BC032469 was identified as a novel ceRNA that upregulates hTERT expression by sponging miR-1207-5p, promoting tumor cell proliferation in gastric cancer [36, 37].
