摘要

The c-Jun N-terminal kinase (JNK/SAPK) signaling cascade controls a spectrum of cellular processes, including cell growth, differentiation, transformation, and apoptosis. We recently demonstrated that stress kinase MKK7, a direct activator of JNKs, couples stress signaling to G2/M cell cycle progression, CDC2 expression, and cellular senescence. We further explored other molecules involved in JNK pathway and found that both MKK4, another direct activator of JNK, and c-Jun, a direct substrate of JNK, have similar roles to MKK7. Here we discuss the importance of the MKK4/MKK7-JNK-c-Jun pathway linking stress and developmental signals to cell proliferation, cell cycle progression, cellular senescence, and apoptosis including recent unpublished data from our lab.
