Several primary murine and human B lymphomas and cell lines were found to constitutively express high levels of the activated form of c-jun N-terminal kinase (JNK), a member of the mitogen-activated protein (MAP) kinase family. Proliferation of murine B lymphomas CH31, CH12.Lx, BKS-2, and WEHI-231 and the human B lymphomas BJAB, RAMOS, RAJI, OCI-Ly7, and OCI-Ly10 was strongly inhibited by SP600...
We have investigated the regulation of kinases and phosphatases in early gene activation in monocytes because these cells are implicated in the pathogenesis of acute inflammatory states, such as sepsis and acute lung injury. One early gene up-regulated by endotoxin is c-Jun, a member of the activating protein (AP) family. C-Jun is phosphorylated by c-Jun N-terminal kinase (JNK) and associates w...
Liver cancer is one of the most drug-resistant cancer types, and cancer stem cells are related to drug resistance. c-Jun-N-terminal kinase (JNK) signaling is involved in drug resistance, and the side population of cells (SP cells) can be used as a model to study liver cancer stem cells. We sought to evaluate the relationship between SP cells and JNK signaling in hepatocarcinoma cells. For this ...
The production of hydrogen peroxide (H2 O2 ) drives tumourigenesis in ulcerative colitis (UC). Recently, we showed that H2 O2 activates DNA damage checkpoints in human colonic epithelial cells (HCEC) through c-Jun N-terminal Kinases (JNK) that induces p21(WAF1) . Moreover, caspases circumvented the G1/S and intra-S checkpoints, and cells accumulated in G2/M. The latter observation raised the qu...
The pathogenesis of bladder pain syndrome/interstitial cystitis (BPS/IC) is currently unclear. However, inflammation has been suggested to play an important role in BPS/IC. JNK downstream signaling plays an important role in numerous chronic inflammatory diseases. However, studies of the JNK pathway in BPS/IC are limited. In this study, we investigated the role of the JNK pathway in human BPS/I...
A new c-Jun N-terminal kinase (JNK)-interacting protein, Sab (SH3BP5), associates with mitochondria.
We have identified a novel c-Jun N-terminal kinase (JNK)-interacting protein, Sab, by yeast two-hybrid screening. Sab binds to and serves as a substrate for JNK in vitro, and was previously found to interact with the Src homology 3 (SH3) domain of Bruton's tyrosine kinase (Btk). Inspection of the sequence of Sab reveals the presence of two putative mitogen-activated protein kinase interaction m...
The mitogen-activated kinases are structurally related proline-directed serine/threonine kinases that phosphorylate similar phosphoacceptor sites and yet, in vivo, they exhibit stringent substrate specificity. Specific targeting domains (kinase docking domains) facilitate kinase-substrate interaction and play a major role in substrate specificity determination. The c-Jun N-terminal kinase (JNK)...
Cytotoxic platinum compounds including cisplatin are standard cancer chemotherapeutics and are also activators of stress-signaling pathways. In this study, we tested the role of the c-Jun N-terminal kinase (JNK) family of mitogen-activated protein kinases and their transcription factor target, c-Jun, in the cytotoxic response of small-cell lung cancer (SCLC) cells to cisplatin and its less effe...
In accord with the central role c-Myc plays in control of cell growth and death, the stability of this protein is tightly regulated. Although the NH2-terminal domain of c-Myc has been implicated in the regulation of its stability, c-Myc-S, which lacks this domain, is equally unstable, pointing to the role of additional domains in the regulation of c-Myc stability. Our former studies revealed th...
