Abstract
The bactericidal/permeability-increasing (BPI) fold-containing (BPIF) superfamily of genes expressed in the brain are purportedly involved in modulating brain function in response to stress, such as inflammation. Kisspeptin, encoded by kiss, is affected by inflammation in the brain; therefore, BPIF family genes might be involved in the modulation of kisspeptin in the brain. In this study, we investigated the expression of BPIF family C, like (bpifcl) in zebrafish brain and its involvement in kiss2 regulation. The identified, full-length sequence of a bpifcl isoform expressed in the zebrafish brain contained the BPI fold shared by BPIF family members. bpifcl mRNA expression in female zebrafish brains was significantly higher than that in males. Exposure of female zebrafish to 11-ketotestosterone decreased bpifcl and kiss2 mRNA expression. bpifcl knockdown by bpifcl-specific small interfering RNA administration to female zebrafish brain decreased kiss2 mRNA expression. bpifcl expression was widely distributed in the brain, including in the dorsal zone of the periventricular hypothalamus (Hd). Furthermore, bpifcl was also expressed in KISS2 neurons in the Hd. These results suggest that the Bpifcl modulates kiss2 mRNA expression under the influence of testosterone in the Hd of female zebrafish.
