Propofol Modulates Gallbladder Cancer Progression via miR-4430/SLC19A3 Axis.

ABSTRACT

Background/Aim: Propofol is a common anesthetic used during surgery. MircoRNA (miRNA), especially miR-4430, is currently a research hotspot in GBC. This study investigates whether propofol regulates GBC through the miR-4430/SLC19A3 axis. Materials and methods: NOZ and SGC996 cells, human gallbladder cancer cell lines, were obtained from BLUEFBIO (Shanghai, China). The cells were treated with propofol, and the experimental setup included a control group. qRT-PCR was used to measure the content of miR-4430 and solute carrier family 19 member 3 (SLC19A3). The cell viability, migration, and apoptosis were analyzed by colony formation assay, wound healing assay, and flow cytometry, respectively. Western blot tested the levels of SLC91A3, cyclin D-dependent kinases 6 (CDK6), and Bax proteins. Mechanically, dual-luciferase reporter assay notarized the link of miR-4430 with SLC19A3. Results: Propofol significantly repressed the proliferation of GBC cells, as indicated by a pronounced reduction in colony formation in both NOZ and SGC996 cells (P = .025, 95% CI1.2, 2.4). The inhibitory effect of propofol was reversed by the enhanced expression of miR-4430 in GBC cells. Furthermore, SLC19A3 was identified as a direct target of miR-4430. Silencing SLC19A3 reversed the altered cell behavior observed in propofol-treated GBC cells (P = .019, 95% CI1.6, 3.5). Additionally, overexpression of SLC19A3 significantly attenuated both cell proliferation and migration influenced by miR-4430 in propofol-treated GBC cells (P = .034, 95% CI1.4, 2.8). Conclusion: Propofol changed the cell behaviors of GBC by modulating the miR-4430/SLC19A3 axis.
