KIFC1 and non-small cell lung carcinoma: Studies have reported that miR-635 acts as an anti-tumor gene in many tumors, for example, miR-635 inhibits tumor proliferation and invasion in non-small cell lung cancer [32], miR inhibit the progression of gastric cancer by targeting KIFC1 [33], and miR-635 is involved in regulation of nasopharyngeal carcinoma as a target gene of circRANBP17 [34].
