This study was conducted to determine if an oral squamous cel carcinoma alters mRNA ex-presion of serotonin transporter (5-HTT) in the central nervous system. KB cell line derived from a human oral squamous cell carcinoma was inoculated into nude mice, and mRNA expres-sion level of 5-HT in the dorsal raphe nucleus in situ hybridization when the tumor mass reached to -10% of total body weight. Plasma leptin levels were determin-ed by radioimunoassay method using a com-mercial kit. 5-HTT mRNA level was significantly decreased in the DRN of tumor bearing mice, compared to the age-matching non-tumor con-trol. Plasma leptin level decreased concomitantly in tumor bearing mice. These results sugest that oral carcinoma may supress 5-HT gene expres-sion in the central nervous system, perhaps in relation with decreased plasma leptin level.
