  • Title: Physiological roles of SAPK/JNK signaling pathway.
    Author: Nishina H, Wada T, Katada T.
    Journal: J Biochem; 2004 Aug; 136(2):123-6. PubMed ID: 15496581.
    Abstract:
    Stress-activated protein kinase/c-Jun NH(2)-terminal kinase (SAPK/JNK) is activated by many types of cellular stresses and extracellular signals. Recent studies, including the analysis with knockout mice, have led to progress towards understanding the physiological roles of SAPK/JNK activation in embryonic development in addition to immune responses. SAPK/JNK activation plays essential roles in organogenesis during mouse development by regulating cell survival, apoptosis, and proliferation. Two SAPK/JNK activators, SEK1 and MKK7, are required for fetal liver formation and full activation of SAPK/JNK, which responds to various stimuli in an all-or-none manner. This article focuses on physiological roles of SAPK/JNK activation in fetal liver formation and in apoptosis regulation.
