Assay Description
DMH-1 (0.5 μM) induced the regulation of OCT4, Nanog and PAX6 protein expression. DMH-1 significantly reduced the percentage of cells expressing the pluripotency marker proteins OCT4 and Nanog in SM3 and CA6 cells. In CA6 and SM3 cells, PAX6 expression was significantly up-regulated on days 5 and 7, respectively. DMH-1 induces the modulation of pluripotency and neural precursor marker mRNA. PAX6 can independently regulate SOX1 expression by manipulating the concentration of DMH-1 during neural induction of hiPSCs [1]. DMH-1 (5μM and 10μM) inhibits CDDP-induced autophagy in HeLa cells, enhances CDDP's ability to reduce HeLa cell viability, inhibits tamoxifen-induced autophagy in MCF-7 cells, and enhances tamoxifen's ability to reduce MCF- ability. After 24 hours of treatment, DMH-1 enhanced the apoptosis induction effect of CDDP on HeLa cells. DMH-1 inhibits the proliferation of HeLa and MCF-7 cells [2]. DMH-1 (20 μM) reduced the typical phosphorylation of Smads 1, 5 and 9. The combination of DMH-1 and cisplatin significantly reduced Ki-67 positive staining of OVCAR8 cells. DMH-1 (20 µM) upregulates JAG1, reduces CYP1B1 and increases HAPLN1 expression in OVCAR8 and NCI-RES cells [3].
