HOXA7 and familial pancreatic carcinoma: We previously reported that a newly designed Antp-TPR hybrid peptide inhibits the interaction of Hsp90 with tetratricopeptide repeat 2A domain (TPR2A) of p60/Hsp-organizing protein (Hop), has selective cytotoxic activity that allows it to discriminate between cancer and normal cell lines, and induces effective antitumor activity in a xenograft model of human pancreatic cancer in mice [20].
