Kinase experiment: | To measure the effects of DC_517 on mouse DNMT1 activity, 200 nM purified DNMT1 is incubated with 200 μM of DC_517 and S-adenosylmethionine (AdoMet) in the DNMT assay buffer in the assay plate at 37°C for 2 h. Next, every sample is incubated with the capture and detection antibody, followed by incubation with developer solution for 10 min at room temperature. The absorbance is measured at 450 nm using a microplate reader. S-Adenosylhomocysteine (AdoHcy) is used as a positive control[1]. |

DC_517 is a DNA methyltransferase 1 (DNMT1) inhibitor, with an IC50 and a Kd of 1.7 μM and 0.91 μM, respectively. DC_517 (1.25, 2.5, 5, and 10 μM) potently inhibits the proliferation of HCT116 (human colon cancer) and Capan-1 (human pancreatic adenocarcinoma cells) after treatment for 24, 48, and 72 h. DC_517 (0, 0.75, 1.5, and 3 μM) also dose-dependently induces apoptotic cell death in HCT116 cells[1].

DNMT1 involved in the analgesic effect of folic acid on gastric hypersensitivity through downregulating ASIC1 in adult offspring rats with prenatal maternal stress
CNS Neurosci Ther 2023 Feb 27.PMID:36852448DOI:10.1111/cns.14131
Aims: Gastric hypersensitivity (GHS) is a characteristic pathogenesis of functional dyspepsia (FD). DNA methyltransferase 1 (DNMT1) and acid-sensing ion channel 1 (ASIC1) are associated with GHS induced by prenatal maternal stress (PMS). The aim of this study was to investigate the mechanism of DNMT1 mediating the analgesic effect of folic acid (FA) on PMS-induced GHS. Methods: GHS was quantified by electromyogram recordings. The expression of DNMT1, DNMT3a, DNMT3b, and ASIC1 were detected by western blot, RT-PCR, and double-immunofluorescence. Neuronal excitability and proton-elicited currents of dorsal root ganglion (DRG) neurons were determined by whole-cell patch clamp recordings. Results: The expression of DNMT1, but not DNMT3a or DNMT3b, was decreased in DRGs of PMS rats. FA alleviated PMS-induced GHS and hyperexcitability of DRG neurons. FA also increased DNMT1 and decreased ASIC1 expression and sensitivity. Intrathecal injection of DNMT1 inhibitor DC-517 attenuated the effect of FA on GHS alleviation and ASIC1 downregulation. Overexpression of DNMT1 with lentivirus not only rescued ASIC1 upregulation and hypersensitivity, but also alleviated GHS and hyperexcitability of DRG neurons induced by PMS. Conclusions: These results indicate that increased DNMT1 contributes to the analgesic effect of FA on PMS-induced GHS by reducing ASIC1 expression and sensitivity.
