ABSTRACT
Cisplatin, known as an anticancer drug, has been widely used; however, diverse disadvantageous side effects, including appetite loss, afflict patients. Nesfatin-1/NucB2, discovered as an anorexic neuropeptide, is broadly expressed in the central nervous system (CNS) and peripheral organ. In the present study, we examined the effects of intraperitoneally (i.p.) administered cisplatin on central nesfatin-1/NucB2. Saline, as control, or cisplatin (6 mg/kg dissolved in saline) was i.p. administered in adult male Wistar rats (180-220 g). Cumulative food intake was remarkably suppressed for at least 24 h and body weight was significantly smaller at 24 h after i.p. administration of cisplatin compared to control group. At 90 min after i.p. administration, they were perfused, followed by carrying out double-immunohistochemistry for Fos and nesfatin-1/NucB2. The percentage of nesfatin-1/NucB2 immunoreactive neurons expressing Fos was marked increased in the hypothalamus and brainstem after i.p. administration of cisplatin. Intracerebroventricularlly administered nesfatin-1/NucB2-antisense resulted in a significant attenuation of decreased food intake for 2 h after i.p. administration of cisplatin compared to nesfatin-1/NucB2-missense treated group. These results suggest that i.p. administration of cisplatin activated, at least in part, nesfatin-1/NucB2 neuron in the CNS and may exert anorexigenic effects in rats.
