OBJECTIVE
This research explored the involvement of MAFG-AS1 in metabolic reprogramming and potential molecular mechanisms in ovarian cancer (OC).
METHODS
The ability of MAFG-AS1 silencing to affect the glucose intake, lactate production, ECAR, OCR and ATP concentrations and NAD/NADH ratios in OC cells was examined. Cell cycle phases and apoptosis were measured by flow cytometry. The influences of MAFG-AS1overexprssion on the above assays were also identified.
RESULTS
A transient reduction in the number of SKOV3 and HO8910 cells in the MAFG-AS1 knockdown group. MAFG-AS1 knockdown can inhibit cell proliferation, induce apoptosis, and enhance the number of cells in G2 phase. Silencing MAFG-AS1 can inhibit the glucose uptake rate, extracellular lactate production, and ECAR of OC cells, ATP levels, and can promote OCR and NAD/ NADH ratio oxidative phosphorylation. Silencing MAFG-AS1 can inhibit HIF-1α in OC.
CONCLUSION
Our study revealed silencing MAFG-AS1 could inhibit the proliferation and induce apoptosis of OC cells by inhibiting the HIF-1α-mediated glycolysis process. Therefore, this study further potentially reveals the machinery of MAFG-AS1 in regulating OC cell proliferation and apoptosis, which is expected to provide a theoretical basis for the study of new targets.
目的
本研究探讨了MAFG-AS1在卵巢癌(OC)代谢重编程中的作用及潜在分子机制。
方法
检测MAFG-AS1沉默对OC细胞葡萄糖摄取、乳酸生成、细胞外酸化率(ECAR)、氧消耗率(OCR)、ATP浓度及NAD/NADH比值的影响。通过流式细胞术检测细胞周期阶段和细胞凋亡情况。还确定了MAFG-AS1过表达对上述检测的影响。
结果
MAFG-AS1敲低组中SKOV3和HO8910细胞数量短暂减少。MAFG-AS1敲低可抑制细胞增殖、诱导细胞凋亡,并增加G2期细胞数量。沉默MAFG-AS1可抑制OC细胞的葡萄糖摄取率、细胞外乳酸生成及ECAR、ATP水平,并可促进OCR及NAD/NADH比值的氧化磷酸化。沉默MAFG-AS1可抑制OC中的缺氧诱导因子-1α(HIF-1α)。
结论
我们的研究表明,沉默MAFG-AS1可通过抑制HIF-1α介导的糖酵解过程来抑制OC细胞的增殖并诱导其凋亡。因此,本研究进一步潜在地揭示了MAFG-AS1在调节OC细胞增殖和凋亡中的机制,有望为新靶点的研究提供理论依据。
