Endocannabinoids enhance the proliferation of neural progenitors
The existence of progenitor cells in the central nervous system is well established, suggesting the existence of neurogenesis in the adult brain. Furthermore, the molecular mechanisms that control cell proliferation that are not well described. In this sense, the work done by the group of Dr. Galve-Roperh (Universidad Complutense de Madrid) is a significant advance in identifying the signals that govern the proliferation of multipotent neural cells.

Understanding how cells organize and coordinate to form the tissues and organs in living organisms (morphogenesis) is a basic question in developmental biology. The morphogenesis requires a number of cellular processes that occur in a coordinated way in small groups of cells, including proliferation, migration, differentiation, growth, and reposicionamento rearrangement of cells within the tissue. The end result of all these processes is to form a body-dimensional structure-from the initial flat structure which are the first cells of the embryo.

The Ras superfamily of GTPases regulate important cellular processes like cell proliferation, differentiation and cell survival, mutations involving the development of cancer. In cancer, apart from the Ras proteins (H-Ras, N-Ras and K-Ras) are also implicated other proteins such as TC21, which shares most of the Ras effectors. TC21 protein may be farnesyl and geranyl, while Ras farnesyl just are. Read the rest of this entry »
