Meta-analysis: Association between promoter hypermethylation of Glutathione S-Transferase P1 (GSTP1) and breastcancer
The association between promoter hypermethylation of Glutathione S-transferase P1 (GSTP1) and breast cancer has been investigated by much previous research worldwide. However, the results of the correlation between the epigenetic features of human genes with breast cancer varied fr...

The association between promoter hypermethylation of Glutathione S-transferase P1 (GSTP1) and breast cancer has been investigated by much previous research worldwide.
