PTBP1 and glioblastoma: It is worth mentioning that the NF-κB activating protein (NKAP), an RNA-binding protein, can regulate mRNA splicing and maturation by binding to N6-methyladenosine (m6A) on the transcript of a ferroptosis defense protein, cystine/glutamate antiport (SLC7A11), making GBM escape death due to ferroptosis [96].
