Examination of the potential mechanism by transcriptome sequencing and CUT&Tag sequencing suggested that HNF3α promoted renal fibrosis by increasing the expression of the NCK associated protein 1 like (Nckap1l, formerly known as hematopoietic protein 1 [Hem1]), a vital component of the WAVE complex which plays a significant role in cytoskeletal regulation and cell migration. Here, WASF1 is linked to renal fibrosis.
