Asymmetric self-renewal associated (ASRA) genes

ABSTRACT: Cell lines geneticially engineered to undergo conditional asymmetric self-renewal were used to identify genes whose expression is asymmetric self-renewal associated (ASRA). Non-random sister chromatid segregation occurs concordantly with asymmetric self-renewal in these cell lines. Asymmetric self-renewal occurs when murine embryo fibroblasts that are otherwise p53-null are induced to express physiological levels of wildtype p53 protein (Asym). To distinguish p53-responsive genes that also require induction of asymmetric self renewal (i.e., ASRA genes) and/or non-random sister chromatid segregation for change, an additional control cell line, which continues to symmetrically self-renew (with random sister chromatid segregation) even when p53 is induced, was also compared (Symp53).
