Given the nuclear export function of YTHDC1, we detected the distribution of NCAPH mRNA after YTHDC1 depletion and found a clear reduction of cytoplasmic NCAPH mRNA levels in ccRCC cells upon YTHDC1 depletion (Figure S3H), indicating that YTHDC1 was implicated in the nuclear export of NCAPH mRNA. Here, YTHDC1 is linked to nonpapillary renal cell carcinoma.
