Licochalcone A (LA) is a chalcone flavonoid of , which has anti-cancer, antioxidant, anti-inflammatory, and neuroprotective effects. However, no anti-aging benefits of LA have been demonstrated or . In this study, we explored whether LA has an anti-aging effect in adipose-derived stem cells (ADSCs). We performed β-galactosidase staining and measured reactive oxygen species, relative telomere lengths, and mRNA expression. Osteogenesis was assessed by Alizarin Red staining and adipogenesis by was assessed Oil Red O staining. Protein levels of related markers runt-related transcription factor 2 and lipoprotein lipase were also examined. RNA sequencing and measurement of glycolysis activities showed that LA significantly activated glycolysis in ADSCs. Together, our data strongly suggest that the LA have an anti-aging effect through activate the glycolysis pathway.
甘草查尔酮 A(LA)是一种查尔酮类黄酮,具有抗癌、抗氧化、抗炎和神经保护作用。然而,尚未证明 LA 具有抗衰老作用。在这项研究中,我们探讨了 LA 是否对脂肪来源的干细胞(ADSCs)具有抗衰老作用。我们进行了β-半乳糖苷酶染色,并测量了活性氧、相对端粒长度和 mRNAs 的表达。通过茜素红染色评估成骨,通过油红 O 染色评估脂肪生成。还检查了相关标志物 runt 相关转录因子 2 和脂蛋白脂肪酶的蛋白水平。RNA 测序和糖酵解活性测量表明,LA 可显著激活 ADSCs 中的糖酵解。总之,我们的数据强烈表明,LA 通过激活糖酵解途径具有抗衰老作用。
