ASAH2 and cancer: Notably, this gene exhibits elevated sensitivity specifically within tumor cells, and its modulation does not affect the normal function of healthy cells.[20] Considering the similarities between scars and tumors such as lack of spontaneous regression, high recurrence rate, and excessive collagen production, and the fact that some cancer therapies have been found effective in scar treatment,[21] we have reason to believe that this ASAH2 gene might be a potential target for scar treatment, although this assumption needs to be confirmed by further investigation.
