The iTRAQ quantitative proteomics identified the significantly upregulated expression of total HSP60 (fold change = 1.43, p = 3.81E − 2), and quantitative phosphoproteomics identified the significantly increased phosphorylation level at residue Ser70 in HSP60 (p-HSP60) (fold change = 2.34, p = 1.70E − 3), in ovarian cancer tissues relative to control ovary tissues (Figure 4(d)). This evidence concerns the gene HSPD1 and ovarian cancer.
