In general, NTN1, NEO1, DSCAM, UNC5C, and UNC5D are all regulated by HDAC members in renal cancer, suggesting that NTN1, NEO1, DSCAM, UNC5C, UNC5D, and especially NEO1 and UNC5C may be essential for the regulation and outcome of renal cancer. This evidence concerns the gene HDAC9 and renal carcinoma.
