NSD1 and head and neck squamous cell carcinoma: Reflecting on the fact that wild-type HNSCC cells demonstrate a decrease in p62 level and no visible changes by western blot in LC3B-II after mTORC1 inhibition alone, without CQ treatment, while NSD1-depleted cells have different profiles of p62, LC3B-II, and ULK1 protein levels, suggested that the effects we observe reflect an impaired autophagic flux upon NSD1 depletion.
