GSK-3484862
Based on 26 publication(s) in Google Scholar
GSK-3484862 is a highly potent non-covalent inhibitor and demethylating agent of DNMT1. GSK-3484862 induces genome-wide DNA demethylation, including the regulatory elements of DNMT3B and the promoter region of TERT, and significantly inhibits cell viability, growth, proliferation and self-renewal. GSK-3484862 blocks the transformation of young AT2 cells, induces apoptosis, and generates transcriptomic features similar to those of senescent cells. GSK-3484862 is widely used in studies related to lung cancer, oral squamous cell carcinoma and lung adenocarcinoma.

GSK-3484862 (2 μM, 10 μM; 6 days) induces global DNA demethylation in mouse embryonic stem cells, reducing the global CpG methylation level of the cells from nearly 70% to less than 18%, and the methylation pattern after induction is similar to that of Dnmt1-/- deficient mouse embryonic stem cells[1].
GSK-3484862 (1-10 μM; 1 week) inhibits proliferation, promotes apoptosis, and reduces the self-renewal capacity of Cal27 and FaDu oral squamous cell carcinoma (OSCC) cells by downregulating the expression of DNMT1[2].
GSK-3484862 inhibits the in vitro transformation of primary alveolar type 2 cells isolated from young KP-Cas9 mice, but has no effect on alveolar type 2 cells from aged KP-Cas9 mice, and induces the expression of Nupr1 and Lcn2 in this system[3].
GSK-3484862 induces hypomethylation at specific CpG sites in Nupr1 enhancers (E1, E7, E8), which correlates with upregulated Nupr1 gene expression[3].

WT hESCs were treated with 2 μM GSK-3484862 for 2 days. Following the removal of GSK3484862, genomic DNA was purified at the indicated time points, and methylation levels at upstream (UP) and downstream (DOWN) of A/B DMR, MCTS2, PEG10, and KCNQ1OT1 were calculated by MSRE-qPCR. The results showed that in the hESCs, methylation levels at the A/B DMR decreased substantially by day 4 following a 2-day treatment with GSK-3484862 (14.1% and 9.2% methylation for the UP and DOWN regions, respectively).
