Abstract:
During apoptosis, executioner caspase activity has been considered a point of no return. However, recent studies show that cells can survive caspase activation following transient apoptotic stimuli, a process called anastasis. To identify a molecular signature, we performed whole-transcriptome RNA sequencing of untreated, apoptotic, and recovering HeLa cells. We found that anastasis is an active, two-stage program. During the early stage, cells transition from growth-arrested to growing. In the late stage, HeLa cells change from proliferating to migratory. Recovering cells also exhibited prolonged elevation of proangiogenic factors. Strikingly, some early-recovery mRNAs, including Snail, were elevated first during apoptosis, implying that dying cells poise to recover, even while under apoptotic stress. Snail was also required for recovery. This study reveals similarities in the anastasis genes, pathways, and cell behaviors to those activated in wound healing and identifies a repertoire of potential targets for therapeutic manipulation.
Insights
Cells can survive apoptosis through a process called anastasis. This recovery involves a two-stage program with gene expression changes, preparing cells for growth and migration, similar to wound healing.
Area of Science:
- Cell Biology
- Molecular Biology
- Apoptosis Research
Background:
- Executioner caspase activity in apoptosis was traditionally viewed as irreversible.
- Recent findings indicate cell survival is possible post-caspase activation, termed anastasis.
- Understanding the molecular mechanisms of cell recovery from apoptosis is crucial.
Purpose of the Study:
- To identify the molecular signature of anastasis.
- To elucidate the stages and genetic programs involved in cell recovery from apoptosis.
- To explore potential therapeutic targets for modulating cell survival.
Main Methods:
- Whole-transcriptome RNA sequencing was performed on HeLa cells.
- Cells were analyzed at untreated, apoptotic, and recovering stages.
- Gene expression patterns and cell behaviors were compared across conditions.
Main Results:
- Anastasis is an active, two-stage program involving transition from growth arrest to growth, then proliferation to migration.
- Recovering cells showed sustained elevation of proangiogenic factors.
- Early-recovery mRNAs, like Snail, were upregulated during apoptosis, indicating pre-recovery states.
Conclusions:
- Dying cells can poise for recovery, even under apoptotic stress, with Snail being essential for this process.
- Anastasis shares gene expression patterns and cell behaviors with wound healing.
- This study identifies potential therapeutic targets for manipulating cell recovery and survival.

Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
