FIGURE 5 | Promoter methylation regulates gene expression level of YTHDC2. (A) Schematic representation of the CpG distribution in promoter region of the YTHDC2 gene from the CpG Island Searcher (https://www.urogene.org/cgi-bin/methprimer/methprimer.cgi). (B) Methylation-specific PCR (MSP) analysis of YTHDC2 promoter methylation status in two pairs of cell lines using 2 serials of primers. (C) YTHDC2 expression in CNE2-IRR and HK1-IRR cells treated with gemcitabine with
