The xenografted tumor volume and weight in nude mice were clearly declined after injection of sh‐DNMT1 and miR‐152‐3p mimic, but apparently elevated following injection of the cells treated with miR‐152‐3p mimic and pcDNA‐DNMT1 when compared with injection of cells treated with miR‐152‐3p mimic only (Figure 6a–c). The gene discussed is DNMT1; the disease is neoplasm.
