.../desiccation resistance, gene redundancy and survival over geological times and at extraterrestrial sites. Experimental indications exist for all but one of these evolutionary advantages. Several of the advantages require gene conversion, which has been shown to be present and active in haloarchaea. 1...

..., proliferation and survival. In the present paper, we review recent evidence highlighting the notion that the TSC1/2 complex simultaneously controls mTOR-dependent and mTOR-independent signals critical for the balancing of cell proliferation and cell death. 1 To whom correspondence should be addressed...

... in mediating multiple VEGF functions, including survival, proliferation, migration, vascular permeability, tubulogenesis, NO and prostanoid synthesis, and gene expression. NO and prostanoids in turn play paracrine and autocrine roles in linking post-receptor signalling to biological functions. Integration...

... at choice points; (iii) glial migration patterns, which are influenced by neurons; (iv) cell survival control, which constrains position and number of both cell types; and (iv) connectivity, where an axon contacts its final target aided by glial cells. Understanding the reciprocal interactions between...
