IL2 and breast carcinoma: We report for the first time transcriptional induction of p53, ATF-2, hsp27, BRCA2, IL-2, p57, and CYP19 by PEITC in the human breast cancer cells, and our results are supported by other studies which have reported increased expression [33] and increased activity [38] of p53 protein and activation of Hsp27 [41].
