Runx2 因子是骨骼发生过程中控制转录的调节机制的重要组成部分。成骨细胞中的 Runx2/p57 表达由 P1 启动子控制,P1 启动子被成骨细胞分化的关键调节因子(包括同源域因子以及 Wnt 和 BMP 信号传导介质)识别。在这里,我们报道转录因子 C/EBPβ 通过直接结合间充质细胞、前成骨细胞和成骨细胞中的 Runx2 P1 启动子来上调 Runx2/p57 的表达。这种 C/EBPβ 介导的上调主要依赖于 C/EBP 位点 II,该位点位于近端 P1 启动子区域的前 180 bp 内,并且在小鼠、大鼠和人类 Runx2 基因中高度保守。我们的研究揭示了已知在成骨过程中起关键作用的 C/EBPβ 因子如何有助于调节成骨细胞分化的主要调节因子 Runx2 的表达。
The Runx2 factor is an essential component of the regulatory mechanisms that control transcription during skeletogenesis. Runx2/p57 expression in osteoblastic cells is controlled by the P1 promoter, which is recognized by key regulators of osteoblast differentiation including homeodomain factors and Wnt- and BMP-signaling mediators. Here, we report that the transcription factor C/EBPβ up-regulates Runx2/p57 expression by directly binding to the Runx2 P1 promoter in mesenchymal, pre-osteoblastic and osteoblastic cells. This C/EBPβ-mediated up-regulation is principally dependent on C/EBP site II that is located within the first 180 bp of the proximal P1 promoter region and is highly conserved among mouse, rat, and human Runx2 genes. Our studies reveal how the C/EBPβ factor, known to have a key role during osteogenesis, contributes to regulating the expression of Runx2, the master regulator of osteoblast differentiation.
