Among other functions, the Notch signaling pathway contributes to the development of somites [4] in animals. It involves a cell signaling mechanism with a wide range of functions, including cellular differentiation [5], and the formation of the embryonic structures (embryogenesis [6]). All multicellular animals use Notch signaling, which is involved in the development, maintenance, and regenera...

The Notch signaling pathway is a highly evolutionarily-conserved cell-cell signaling pathway that regulates many events during development. It plays a pivotal role in the regulation of fundamental cellular processes, such as cell proliferation, stem cell maintenance, and differentiation during embryonic and adult development. However, functions of Notch signaling in Aedes aegypti, the major mos...

We examined the roles of Notch signaling and fibroblast growth factors (FGFs) in the gliogenesis of mouse mesencephalic neural crest cells. The present study demonstrated that Notch activation or FGF treatment promotes the differentiation of glia expressing glial fibrillary acidic protein. Notch activation or FGF2 exposure during the first 48 h in culture was critical for glial differentiation....

The Notch signaling pathway controls diverse cell-fate specification events throughout development. The versatility of this pathway to influence different aspects of development comes from its multiple levels of regulation. Upon ligand-induced Notch activation, the Notch intracellular domain (Notch-ICD) is released from the membrane and translocates to the nucleus, where it transduces Notch sig...

Notch signaling is an important molecular pathway involved in the determination of cell fate. In recent years, this signaling has been frequently reported to play a critical role in maintaining progenitor/stem cell population as well as a balance between cell proliferation, differentiation and apoptosis. Thus, Notch signaling may be mechanistically involved carcinogenesis. Indeed, many studies ...

The Notch signaling pathway plays fundamental roles in diverse developmental processes. Studies of the basic biology of Notch function have provided insights into how its dysfunction contributes to multi-systemic diseases and cancer. In addition, our understanding of Notch signaling in maintaining stem/progenitor cell populations is revealing new avenues for rekindling regeneration. The Notch I...

Breast cancer mortality is principally due to recurrent tumors that arise from a reservoir of residual tumor cells that survive therapy. Remarkably, breast cancers can recur after extended periods of clinical remission, implying that at least some residual tumor cells pass through a dormant phase prior to relapse. Nevertheless, the mechanisms that contribute to breast cancer recurrence are poor...

The Notch signaling pathway is required in both nonneoplastic neural stem cells and embryonal brain tumors, such as medulloblastoma, which are derived from such cells. We investigated the effects of Notch pathway inhibition on medulloblastoma growth using pharmacologic inhibitors of gamma-secretase. Notch blockade suppressed expression of the pathway target Hes1 and caused cell cycle exit, apop...
