GenomicsChromatinized PKC-q directly regulates inducible genes in epithelial to mesenchymal transition and breast cancer stem cells
Epithelial to mesenchymal transition (EMT) is activated during cancer invasion and metastasis, enriches for cancer stem cells (CSCs), and contributes to therapeutic resistance and disease recurrence. Signal transduction kinases play a pivotal role as chromatin-anchored proteins in eukaryotes. Here w...

TranscriptomicsProtein Kinase C Mediated Extraembryonic Endoderm Differentiation of Human Embryonic Stem Cells
Unlike mouse embryonic stem (ES) cells, which are closely related to the inner cell mass, human ES cells appear to be more closely related to the later primitive ectoderm. For example, human ES cells and primitive ectoderm share a common epithelial morphology, growth factor requirements, and the po...

ProteomicsPKC isoforms activate LRRK1 kinase by phosphorylating conserved residues (Ser1064, Ser1074 and Thr1075) within the CORB GTPase domain
Leucine-rich-repeat-kinase 1 (LRRK1) and its homologue LRRK2 are multidomain kinases possessing an atypical ROC-CORA-CORB containing GTPase domain and phosphorylate distinct Rab proteins. LRRK1 loss of function mutations cause the bone disorder osteosclerotic metaphyseal dysplasia, whereas LRRK2 mis...

TranscriptomicsInduction of Senescence in Diterpene Ester-Treated Melanoma Cells via PKC-dependent Hyperactivation of the MAPK Pathway
The diterpene ester PEP005 is a novel anticancer agent that activates PKC and cures subcutaneous murine melanoma by topical application. We now describe the in vitro cytostatic effects of PEP005 and the diterpene ester TPA, observed in 20% of human melanoma cell lines. Primary cultures of normal h...

TranscriptomicsPKC Activation Induces Inflammatory Response and Cell Death in Human Bronchial Epithelial Cells
A variety of airborne pathogens can induce inflammatory responses in airway epithelial cells, which is a crucial component of host defence. However, excessive inflammatory responses and chronic inflammation also contribute to different diseases in the respiratory system. We hypothesized that the ac...

TranscriptomicsProtein Kinase C Alpha Promotes Tumor Growth by Initiating a Feed-forward Network Involving miR-15a and Cyclin E
Protein Kinase C alpha (PKC) is associated with progression and poor prognosis in head and neck cancer. Previous studies have demonstrated that PKC sustains the proliferative signal by increasing cyclin E expression, leading to enhanced E2F target gene transcription and DNA synthesis. Here we show ...

TranscriptomicsTranscription profiling of human squamous cell carcinoma of the head and neck cells reveals tumor growth and prognosis of squamous cell carcinoma of the head and neck is linked to protein kinase C alpha
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...

MetabolomicsStress-related mitogen-activated protein kinases stimulate the accumulation of small molecules and proteins in Arabidopsis thaliana root exudates
A delicate balance in cellular signaling is required for plants to distinguish mutualist from parasitic organisms in its environment. Mitogen-activated protein kinase (MAPK) cascades are one of the signaling modules that mediate transduction of extracellular microbial signals into appropriate cellul...

TranscriptomicsTranscription profiling of mouse PKCa -/- mutant vs. wild type small intestine
Members of the PKC family of serine / threonine kinases play key regulatory roles in numerous cellular processes including differentiation and proliferation. Of the eleven mammalian PKC isoforms known several have been implicated in tumor development and progression. However, in most cases isotype s...
