IB1/JIP-1 controls JNK activation and increased during prostatic LNCaP cells neuroendocrine differentiation.
Tawadros T, Martin D, Abderrahmani A, Leisinger HJ, Waeber G, Haefliger JA. Tawadros T, et al. Among authors: abderrahmani a. Cell Signal. 2005 Aug;17(8):929-39. doi: 10.1016/j.cellsig.2004.11.013. Epub 2005 Mar 3. Cell Signal. 2005. PMID: 15894166
We investigated the functional role of IB1/JIP-1 in LNCaP cells exposed to the proapoptotic agent N-(4-hydroxyphenyl)retinamide (4-HPR) which induced a reduction of IB1/JIP-1 content and a concomittant increase in JNK activity. Conversely, IB1/JIP-1 overexpression u …

Beeler N, Riederer BM, Waeber G, Abderrahmani A. Beeler N, et al. Among authors: abderrahmani a. Brain Res Bull. 2009 Oct 28;80(4-5):274-81. doi: 10.1016/j.brainresbull.2009.07.006. Epub 2009 Jul 16. Brain Res Bull. 2009. PMID: 19616077 Review.
These events may have a causal role in the pathogenesis of the two diseases. Increased c-Jun NH(2)-terminal kinase (JNK) activity is found in neurofibrillary tangles (NFT) of AD and promotes programmed cell death of beta-cells exposed to a diabetic environment. The …
