Abstract

BACKGROUND

Obesity is a significant global public health issue linked to numerous chronic diseases, including diabetes, cardiovascular conditions, and various cancers. The vacuolar H + ATPase, a multi-subunit enzyme complex involved in maintaining pH balance, has been implicated in various health conditions, including obesity-related diseases.

METHOD

This study conducts a comprehensive analysis of V-ATPase subunits' roles in adipogenesis within the context of obesity, using knockdown and RNAseq technologies.

RESULT

This study conducts a comprehensive analysis of V-ATPase subunits' roles in adipogenesis, highlighting specific subunits, v0d2 and v1a, which show significant expression alterations. Our findings reveal that v1a plays a crucial role in adipocyte differentiation through pathways related to steroid and cholesterol metabolism.

CONCLUSION

This study provides a comprehensive analysis of the roles played by V-ATPase subunits in adipogenesis and finds the critical role of V-ATPase subunits, particularly v1a, in the differentiation of adipocytes and their potential impact on obesity.

摘要

背景

肥胖是一个全球性的重大公共卫生问题,与许多慢性疾病有关,包括糖尿病、心血管疾病和各种癌症。液泡 H + ATP 酶是一种参与维持 pH 平衡的多亚基酶复合物,与包括肥胖相关疾病在内的各种健康状况有关。

方法

本研究使用 knockdown 和 RNAseq 技术,综合分析 V-ATPase 亚基在肥胖相关脂肪生成中的作用。

结果

本研究综合分析了 V-ATPase 亚基在脂肪生成中的作用,突出了特定的亚基 v0d2 和 v1a,它们显示出显著的表达变化。我们的研究结果表明,v1a 通过与类固醇和胆固醇代谢相关的途径,在脂肪细胞分化中发挥关键作用。

结论

本研究全面分析了 V-ATPase 亚基在脂肪生成中的作用,发现 V-ATPase 亚基,特别是 v1a,在脂肪细胞分化中起着关键作用,其对肥胖的潜在影响值得关注。
