Protein Kinase C alpha (PKC) is a critical mediator of cell signaling and cancer growth. We show that PKC inhibitors decrease proliferation in squamous cell carcinoma of the head and neck (SCCHN) cells and abrogate growth of SCCHN tumors in mouse xenografts. Analysis of gene expression arrays reveal...

Efficacy of the Multi-Kinase Inhibitor Enzastaurin is Dependent on Cellular Signaling Context Testing a panel of SCCHN cell lines revealed variable sensitivity to enzastaurin which correlated significantly with baseline cyclin D1 protein expression. Moreover, sensitivity and resistance could be reve...

Patient selection and specimen collection. Thirty-six freshly frozen tumor samples were prospectively collected from patients undergoing surgery or biopsy for HNSCC at the University of North Carolina (UNC) at Chapel Hill (21 patients) and Vanderbilt University (15 patients). All tissues were snap-f...
