Furthermore, recombinant adenovirus-mediated overexpression of KRT10 and PTEN enhanced the inhibitory effect of cisplatin on C13K xenograft tumor growth.
In summary, we show that P-cadherin contributes to the keratinocyte differentiation in the oral epithelium by influencing the CK1 and CK10 expression via C/EBP-beta-mediated signaling in normal but not in tumor derived oral keratinocytes from OSCC patients.
The expression of three cytokeratin genes (KRT1, KRT10 and KRT19), the matrix metalloproteinase 9 gene (MMP9) and the tumor suppressor TP53 gene was measured by qRT-PCR in surgical samples of pediatric and adult cholesteatoma cases and their expression level was compared to that of normal skin samples from the retroauricular region of control individuals.
