چکیده انگلیسی
Abnormal methylation of the promoter of several genes is common in patients with acute lymphoblastic leukemia. Methylation of DNA is brought about by DNA methyltransferases (DNMT). Bovine lactoferricin (Lfcin B) is a cationic peptide that possesses potent in vitro and in vivo anticancer activity and might affect the expression of DNMT1. In the current study, we determined the mRNA and protein expression of DNMT1 in Jurkat T-leukemia cells, after incubation with Lfcin B, by real-time quantitative reverse transcription PCR and Western blot analysis. The results of real-time quantitative reverse transcription PCR showed that DNMT1 expression in Jurkat T-leukemia cells was reduced after treatment with Lfcin B, and Lfcin B reduced the half-life of DNMT1 mRNA from approximately 8 to 2Â h. The results of Western blot analysis showed that the expression of DNMT1 protein was down-modulated by Lfcin B in Jurkat T-leukemia cells. Moreover, we found that protein biosynthesis in Jurkat T-leukemia cells was essential for Lfcin B to down-modulate the expression of DNMT1.
