Kim et al. [13] found that Carnitine O-palmitoyltransferase 1 (CPT1B), Palmitoyl thioesterase CPT1C (CPT1C), Mitochondrial carnitine/acylcarnitine carrier protein (SLC25A20), Carnitine O-acetyltransferase (CRAT), TPH1, and Type I iodothyronine deiodinase (IOD1) were significantly downregulated in tumor tissues using reverse transcription PCR (RT-PCR) compared with normal bladder tissues of patients with NMIBC and TPH1 were downregulated in those with MIBC. The gene discussed is SLC25A20; the disease is neoplasm.
