Only a few proteomic studies have been conducted in cervical carcinoma (Bae et al, 2005; Choi et al, 2005; Lee et al, 2005; Lin et al, 2006), for which proteins such as annexin A2, tropomyosin 1 and 2, peroxiredoxin 2 and HSP 27 have been pointed out as potential diagnostic markers. This evidence concerns the gene PRDX2 and cervical carcinoma.
