Expression of psoriasin in human lung and cervical tumors determined by immunohistochemistry Upper panel shows the scatter plot chart of level of expression (assessed by IHC score) in different lung tumor types (SqC = squamous cell carcinoma, AdC = adenocarcinoma, SmC = small cell carcinoma, Mes = mesothelioma). Bars represent the median scores. P value determined by t-test. Lower panel shows the scatter plot chart of level of expression (assessed by IHC score) in different cervical lesions corresponding to early stages of cervical tumor progression (metaplasia, CIN = cervical intra-epithelial squamous neoplasia, stages 1, 2, and 3, SqC = squamous cell carcinoma invasive, AdC = cervical adenocarcinoma, in-situ and invasive). P values determined by t-test.
