LRRC1 是细胞极性的调节因子,在多种肿瘤组织类型中高水平表达。在这里,我们对 LRRC1 作为脂肪形成分化网络的组成部分的先前未探索的作用进行了分析。在人间充质干细胞 (MSC) 的早期(第 3-7 天)脂肪细胞分化期间,发现 LRRC1 在 mRNA 和蛋白质水平上均上调。此外,LRRC1 的表达被发现受 PPARγ 控制,PPARγ 是脂肪生成的关键转录调节因子。抑制 LRRC1 表达会降低 hMSC 的脂肪形成潜力,同时减少三种脂肪形成相关蛋白(SCD、LIPE、FASN)的表达。总之,这些数据为 LRRC1 的功能重要性提供了新的见解,无论是在一般情况下还是在脂肪细胞分化的背景下。
LRRC1 is a regulator of cellular polarity that is expressed at high levels in a range of tumor tissue types. Here, we conducted an analysis of the previously unexplored role of LRRC1 as a component of the adipogenic differentiation network. During the early stage (days 3–7) adipocytic differentiation of human mesenchymal stem cells (MSCs), LRRC1 was found to be upregulated at both the mRNA and protein levels. Moreover, the expression of LRRC1 was found to be controlled by PPARγ, which is a key transcriptional regulator of adipogenesis. Inhibiting LRRC1 expression reduced the adipogenic potential of hMSCs, with a concomitant reduction in the expression of three adipogenesis-associated proteins (SCD, LIPE, FASN). Together, these data offer new insight into the functional importance of LRRC1 both in general and in the context of adipocytic differentiation.
