OAC2 是一种 OCT4 激活剂，通过 OCT4 基因启动子激活表达， 通过提高胚胎成纤维细胞诱导多能干细胞的产生速率来提高重编程效率，是 OAC1 的类似物。

OAC2 is an Oct4 activator which activates expression through the Oct4 gene promoter; enhances reprogramming efficiency by increasing the rate of production of induced pluripotent stem cells (iPSCs) from embryonic fibroblasts; an analog of OAC1.

Octamer-binding transcription factor 4 (Oct4) is a master regulator of the induction and maintenance of cellular pluripotency, and has crucial roles in early stages of differentiation. It is the only factor that cannot be substituted by other members of the same protein family to induce pluripotency[1]. Oct4 has been shown to be an essential regulator of embryonic stem cell (ESC) pluripotency and key to the reprogramming process. OAC2 is a structural analog of OAC1 that activates both Oct4 and Nanog reporters to a similar extent as OAC1. OAC1 and its two structural analogs OAC2 and OAC3 enhances reprogramming efficiency fourfold, up to as high as 2.75%, and accelerates the appearance of iPSC colonies 3 to 4 d when used in combination with the four reprogramming factors, Oct4, Sox2, Klf4, and c-Myc[2].

The Oct4-luc or Nanog-luc cells are treated with compound OAC1 or its structural analogs OAC2, OAC3 at 1 μM concentration or at indicated concentrations. Other compounds used include 2 μM BIO, 2 μM BIX, 2 μM 5'-azacytidine, 25 μg/mL Vitamin C, 10 nM Am580, 5 μM tranylcypromine, and 0.5 mM valporic acid. Luciferase reporter assays are performed 24 h after compound treatment or at indicated time points. For Topflash reporter assays, 0.2 μg β-catenin–responsive Topflash reporter gene plasmid is introduced into CV1 cells using trasfection. Compounds are added 6 h after transfection. Luciferase activity is measured 48 h after compound treatment using the Glo Luciferase Assay System[2].
