The second exception was the significantly lower ATOH1 mRNA levels (p = 4.38 × 10−7, Table S2B) in all VP-MCC-like tumors than VP-MCC cell lines, which might be due to the incipient tumor status of VP-MCC-like tumors versus the advanced cancer stage of these VP-MCC cell lines [58]. The gene discussed is ATOH1; the disease is Merkel cell skin cancer.
