Protein kinase Ci (PKCi) is an atypical PKC isoform and participates in multiple aspects of the transformed phenotype in human cancer cells. We previously reported that frequent amplification and overexpression of PKCi were correlated with lymph node metastasis in primary esophageal squamous cell carcinomas (ESCC). In the present study, short interfering RNA–mediated silencing of PKCi revealed ...
Ductal carcinoma in situ (DCIS) is characterized by ductal epithelial cells that have filled the luminal space of the breast duct and survive despite loss of extracellular matrix contact. In normal epithelial cells, the loss of such contact triggers a form of apoptosis known as detachment-induced apoptosis or "anoikis." TMS1/ASC is a bipartite adaptor molecule that participates in inflammatory ...
Smad proteins transduce signals carried by the transforming growth factor (TGF) cytokine superfamily from receptor serine/threonine kinases at the cell surface to the nucleus, thereby affecting cell proliferation, differentiation, as well as pattern formation during early vertebrate development. Smad4/DPC4, located at chromosome 18q21, was identified as a candidate tumor suppressor gene that is...
BACKGROUND During epithelial morphogenesis, a complex comprising the βPIX (PAK-interacting exchange factor β) and class I PAKs (p21-activated kinases) is recruited to adherens junctions. Scrib, the mammalian ortholog of the Drosophila polarity determinant and tumor suppressor Scribble, binds βPIX directly. Scrib is also targeted to adherens junctions by E-cadherin, where Scrib strengthens cadhe...
Smad proteins transduce signals carried by the transforming growth factor beta (TGF-beta) cytokine superfamily from receptor serine/threonine kinases at the cell surface to the nucleus, thereby affecting cell proliferation, differentiation, as well as pattern formation during early vertebrate development. Smad4/DPC4, located at chromosome 18q21, was identified as a candidate tumor suppressor ge...
BACKGROUND Resistance to anoikis, which is defined as apoptosis induced by loss of integrin-mediated cell attachment to the extracellular matrix, is a determinant of tumor progression and metastasis. We have previously identified the mitochondrial Bit1 (Bcl-2 inhibitor of transcription) protein as a novel anoikis effector whose apoptotic function is independent from caspases and is uniquely con...
