From the stand-point of the "insurance effects," co-adhesion of functionally complementing cells, which is indicated in the study by curli formation, enhances bacterial survival, protects cells from injury, promotes communication between cells, and facilitates a coordinated behavior [48].
Size itself was an advantage in survival, protecting against predators, for example.
Stress proteins play an important role for intracellular survival protecting M. tuberculosis against oxidative, nitrosative and/or acidic stresses [4].
As predicted from this group of substances, GDAsBMP support neuronal survival, protect from oxidative stress and increase expression of synaptic proteins in the lesioned striatum.
DG improved H9c2 cell survival, protected the integrity of cell membrane skeleton, decreased the mitochondrial depolarization, decreased proapoptotic and increased anti-apoptotic protein in a dose-dependent manner.
The CREB family of transcription factors is activated by phosphorylation; they promote neuronal survival, protecting neurons from excitotoxicity and apoptosis by regulating the transcription of pro-survival factors (Lonze and Ginty 2002; Mantamadiotis et al. 2002).
TryS and TR are necessary for Leishmania survival, protecting the parasite from oxidative damage and toxic heavy metals, and allowing the delivery of the reducing equivalents for DNA synthesis.
In addition, experimental studies have shown that E-cadherin-mediated cell cell adhesion promotes cell survival protecting tumour cells from chemotherapy and from destruction while in the circulation as tumour cell clumps (St Croix and Kerbel, 1997; Kantak and Kramer, 1998; Gillett et al, 2001; Friedl et al, 2004).
Cellular survival machinery protects mitochondrial integrity against endogenous or exogenous stresses.
Furthermore, gene ablation experiments in mice showed that Raf-1 is required for survival and protects against apoptosis [ 43, 44].
OXR1 improves motor function, increases motor neuron survival, and protects against oxidative stress in the SOD1G93A spinal cord (Fig. 3).
