Parasites Vectors doi.org/10.1186/s13071-022-05593-Parasites VectorsOpen AccessRESEARCHCapsaicin decreases fecundity in the Asian malaria vector Anopheles stephensi by inhibiting the target of rapamycin signaling pathwayJing Wang1, Shasha Yu1, Luhan Wang1, Tingting Liu1, Xuesen Yang1, Xiaobing Hu2 and Ying Wang1Abstract Background: Mosquito-borne ailments threaten human well being, but mosquito control faces a variety of challenges, including resistance to chemical insecticides. As a result, there’s an urgent will need for extra successful and environment-friendly control agents. Capsaicin can downregulate the mTOR signaling pathway of tumor cells. The TOR signaling pathway can mediate the expression of vitellogenin (Vg) to regulate the fecundity of insects. No matter whether capsaicin has the prospective to inhibit fecundity of mosquitoes by regulating TOR pathway and Vg expression is currently unclear. Procedures: Anopheles stephensi had been fed with blood of mice administered capsaicin by gavage or sugar containing capsaicin followed by a blood feeding with typical mice. Then, the engorged female mosquitoes were tubed individually and underwent oviposition. The eggs and individuals inside the subsequent development stages, such as larvae, pupae, and emerging adults, had been counted and compared among the capsaicin treatment and handle groups. Also, total RNA and protein were extracted in the engorged mosquitoes at 24 h post blood feeding.Tasosartan Protocol Real-time PCR and western blot were performed to detect the transcriptional level and protein expression with the crucial fecundity-related molecules of mosquitoes.Pepinemab Cancer Ultimately, TOR signaling pathway was inhibited by means of rapamycin therapy, and modifications in fecundity as well as the essential molecule transcription and protein expression levels were examined to confirm the role of TOR signaling pathway within the effect of capsaicin on mosquito fecundity.PMID:23341580 Results: The laid and total eggs (laid eggs plus retained eggs) of An. stephensi were substantially reduced by feeding on the blood of capsaicin-treated mice (P 0.01) or capsaicin-containing sugar (P 0.01) compared with those in the control group. Additionally, the transcription and protein expression or phosphorylation levels of fecundity-related molecules, like Akt, TOR, S6K, and Vg, have been significantly decreased by capsaicin treatment. Nevertheless, the effects disappeared in between handle group and CAP group after the TOR signaling pathway was inhibited by rapamycin. Conclusions: Capsaicin can lower the fecundity of An. stephensi by inhibiting the TOR signaling pathway. These information will help us to not merely understand the effect of capsaicin on the reproducti.
