Fig. 8From: Identification of prothymosin alpha (PTMA) as a biomarker for esophageal squamous cell carcinoma (ESCC) by label-free quantitative proteomics and Quantitative Dot Blot (QDB)The PTMA expression was up-regulated gradually along the progression of ESCC. a The PTMA expression trend at the different Grades in QDB samples. b The PTMA expression trend at the different Grades in IHC samples. I, II, III represented ESCC Grade I, Grade II and Grade III respectively. (*P < 0.05)Back to article page
