PELI1 and pachyonychia congenita: PELI1 is overexpressed in PC, which increased ubiquitination of RPS3 proteins and activates the PI3K/Akt/GSK3β signaling pathway, as well as reduces the protective effect of RPS3 on p53 and promotes the degradation of the p53 protein, which facilitates the progression of PC and leads to a poor prognosis for patients.
