Among these relevant genes, NAAA encodes a highly similar N-acyl ethanolamine hydrolase (NAEs) to acid neuraminidase, which has been reported to play an important role in BLCA cell migration and induction of tumor cell death and may be a therapeutic target for relevant inhibitors.[26] The remaining genes are first reported to be associated with the prognosis of BLCA. This evidence concerns the gene NAAA and neoplasm.
