“…Many reports on the analysis, standardization, and mode of action of senna, sennosides, and anthraquinones are in the literature (1)(2)(3). Cathartic pharmacology has been the subject of reviews and has involved the parasympathetic system, however, the basic mechanisms of peristaltic activity remain undefined (4)(5)(6).…”

Background Stem cells have been extensively explored for a variety of regenerative medical applications and they play an important role in clinical treatment of many diseases. However, the limited amount of stem cells and their tendency to undergo spontaneous differentiation upon extended propagation in vitro restrict their practical application. Octamer-binding transcription factor-4 (Oct4), a transcription factor belongs to the POU transcription factor family Class V, is fundamental for maintaining self-renewal ability and pluripotency of stem cells. Methods In the present study, we used the previously constructed luciferase reporters driven by the promoter and 3’-UTR of Oct4 respectively to screen potential activators of Oct4. Colony formation assay, sphere-forming ability assay, alkaline phosphatase (AP) activity assay and teratoma-formation assay were used to assess the role of modaline sulfate (MDLS) in promoting self-renewal and reinforcing pluripotency of P19 cells. Immunofluorescence, RT-PCR, and western blotting were used to measure expression changes of stem-related genes and activation of related signaling pathways. Results We screened 480 commercially available small-molecule compounds and discovered that MDLS greatly promoted the expression of Oct4 at both mRNA and protein levels. Moreover, MDLS significantly promoted the self-renewal capacity of P19 cells. Also, we observed that the expression of pluripotency markers and alkaline phosphatase (AP) increased significantly in MDLS-treated colonies. Furthermore, MDLS could promote teratoma formation and enhanced differentiation potential of P19 cells in vivo. In addition, we found that in the presence of LIF, MDLS could replace feeder cells to maintain the undifferentiated state of OG2-mES cells (Oct4-GFP reporter gene mouse embryonic stem cell line), and the MDLS-expanded OG2-mES cells showed an elevated expression levels of pluripotency markers in vitro. Finally, we found that MDLS promoted Oct4 expression by activating JAK/STAT3 and classic Wnt signaling pathways, and these effects were reversed by treatment with inhibitors of corresponding signaling pathways. Conclusions These findings demonstrated, for the first time, that MDLS could maintain self-renewal and pluripotency of stem cells.
