Anastasis (Greek for "rising to life") is a cell recovery phenomenon that rescues
dying cells from the brink of cell death. We recently discovered anastasis to
occur after the execution-stage of apoptosis in vitro and in vivo. Promoting
anastasis could in principle preserve injured cells that are difficult to
replace, such as cardiomyocytes and neurons. Conversely, arresting anastasis in
dying cancer cells after cancer therapies could improve treatment efficacy. To
develop new therapies that promote or inhibit anastasis, it is essential to
identify the key regulators and mediators of anastasis - the therapeutic targets.
Therefore, we performed time-course microarray analysis to explore the molecular
mechanisms of anastasis during reversal of ethanol-induced apoptosis in mouse
primary liver cells. We found striking changes in transcription of genes involved
in multiple pathways, including early activation of pro-cell survival,
anti-oxidation, cell cycle arrest, histone modification, DNA-damage and
stress-inducible responses, and at delayed times, angiogenesis and cell
migration. Validation with RT-PCR confirmed similar changes in the human liver
cancer cell line, HepG2, during anastasis. Here, we present the time-course
whole-genome gene expression dataset revealing gene expression profiles during
the reversal of apoptosis. This dataset provides important insights into the
physiological, pathological, and therapeutic implications of anastasis.
