Epidermal growth factor-induced cyclooxygenase-2 expression is mediated through phosphatidylinositol-3 kinase, not mitogen-activated protein/extracellular signal-regulated kinase kinase, in recurrent respiratory papillomas.
Overexpression of manganese superoxide dismutase suppresses tumor formation by modulation of activator protein-1 signaling in a multistage skin carcinogenesis model.
Differential induction of Cyp1a1, Cyp1b1, Ahd4, and Nmo1 in murine skin tumors and adjacent normal epidermis by ligands of the aryl hydrocarbon receptor.
We hypothesize that it is characterized by higher frequency of p53 genetic mutations and increased AgNOR values compared with squamous cell papilloma(SCP) and basal cell carcinoma (BCC).
There was a marked increase in p53 protein expression in foci of dysplasia and carcinoma as compared to squamous papilloma and pulmonary papillomatosis.
A rat homologue of the human 50-kDa type I cytokeratin 14 was cloned for the first time and shown to be expressed preferentially in squamous cell papillomas and carcinomas, whereas it was weakly expressed or absent in normal squamous epithelial cells and in hyperplastic lesions.
