DNM1L and neuroblastoma: In an independent study, performed in N2a cells (a murine neuroblastoma cell line), H2S (in this case, administered exogenously to the cells) was found to inhibit mitochondrial fission; in this case the molecular mechanism was attributed to the downregulation of dynamin 1 like protein (Drp1) mRNA and protein expression by H2S, most likely through the modulation of ERK1/2 activity [95].
