Curcumin Down-Regulates DNA Methyltransferase 1 and Plays an Anti-Leukemic Role in Acute Myeloid Leukemia - 0 views
-
In a variety of solid tumors and blood cancers, aberrant hypermethylation of CpG-rich regions (>55% CG content, 0.5-4 kb in length, the so-called “CpG islands”) in the promoters of tumor suppressor genes (TSGs) results in their transcriptional silencing
-
These agents have been reported to suppress tumor growth by reversing aberrantly hypermethylation in the promoters of inactivated TSGs (e.g. p15INK4B), allowing re-expression of TSGs, thereby restoring normal cell cycle regulation, proliferation, apoptosis, and differentiation

groups have reported that curcumin acts as a scavenger of free radicals [13], an inhibitor of NF-κB nuclear translocation [14], and a modulator of histone deacetylase (HDAC) and histone acetyltransferase (HAT)
