Recently, the activation of ERK signaling has been shown to be required to initiate regeneration in planarians. However, how ERK signaling is activated remains unknown. Reactive Oxygen Species (ROS) are well-known early signals necessary for regeneration in several models, including planarians. Still, the probable interplay between ROS and MAPK/ERK has not yet been described. Here, by interfering with major mediators (ROS, EGFR and MAPK/ERK), we were able to identify wound-induced ROS, and specifically H<sub>2</sub>O<sub>2</sub>, as upstream cues in the activation of regeneration. Our data demonstrate new relationships between regeneration-related ROS production and MAPK/ERK activation at the earliest regeneration stages, as well as the involvement of the EGFR-signaling pathway. Our results suggest that (1) ROS and/or H<sub>2</sub>O<sub>2</sub> have the potential to rescue regeneration after MEK-inhibition, either by H<sub>2</sub>O<sub>2</sub>-treatment or light therapy, (2) ROS and/or H<sub>2</sub>O<sub>2</sub> are required for the activation of MAPK/ERK signaling pathway, (3) the EGFR pathway can mediate ROS production and the activation of MAPK/ERK during planarian regeneration.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reactive oxygen species rescue regeneration after silencing the MAPK–ERK signaling pathway in <i>Schmidtea mediterranea</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:32:21.934619","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-10-05","DateCreate":"2021-10-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000621765000034","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-020-79588-1"},"refs":null,"anarec":{"AnaID":345604,"PubliDate":2021,"Pagination":"881","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
