HMOX1 and renal carcinoma: Lentivirus-mediated miR-27a-5p modulation verified its role in renal cancer proliferation, and Western blot detection of autophagy marker LC3 expression clarified the miR-27a-5p/LC3 axis involvement in the anti-renal cancer effects of 18β-GA.<h4>Results</h4>Research shows 18β-GA may exert anti-renal cancer effects by targeting HMOX1, HCK, CASP1 and IDO1, with its mechanism linked to the autophagy pathway via functional enrichment analysis; whole transcriptome sequencing identified miR-27a-5p as the most significantly altered by 18β-GA in renal cancer cells.
