NCAPH and nonpapillary renal cell carcinoma: 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.
