2004, Journal of Biological ChemistryCitation Excerpt :Understanding which steps are more unique than others offers the potential for specific therapeutic strategies. In animal studies, p53 has been shown to be dispensable for normal survival and development, because p53 null mice develop normally, albeit with a greater susceptibility to tumorigenesis (65, 66). Moreover, sensory and sympathetic neurons from the p53 knockout mice, as with normal mice, can survive in culture with the addition of neurotrophins (67).

2000, Brain ResearchCitation Excerpt :In contrast, other genes such as bcl-2, Bcl-XL, mcl-1 and Ras show anti-apoptotic activity [3, 22, 41]. In regard to p53 gene function, apoptosis follows a p53-independent pathway in the peripheral nervous system [9, 42] and a p53-dependent pathway in the central nervous system [52]. Although factors inducing p53 gene expression have not been well defined yet, DNA damage is thought to be the most possible [29].
