Express ion of Hea t Shock Prote in 70、c-fos and PCNA in Breast Cancer

Objective to study the relationship of HSP70 expression and c fos?PCNA expression in breast cancer. Methods Immunohistochemical S P methods was used to detect the expression of HSP70?c fos?PCNA in 66 cases of breast cancer. Results the positive rate of HSP70 in breast cancer was 71%(47/66).The positive rate of c fos was 56%(37/66) and PCNA positive rate was 65%(43/66).There was correlativity between the positive grades of HSP70 and c fos( P <0.01).The positive grades of HSP70 and PCNA were closely c...
