mosquitoes transmit the human malaria parasite , which causes the majority of fatal malaria cases worldwide. The hematophagous lifestyle defines mosquito reproductive biology and is exploited by for its own sexual reproduction and transmission. The two main phases of the mosquito reproductive cycle, previtellogenic (PV) and postblood meal (PBM), shape its capacity to transmit malaria. Transition between these phases is tightly coordinated to ensure homeostasis between mosquito tissues and successful reproduction. One layer of control is provided by microRNAs (miRNAs), well-known regulators of blood meal digestion and egg development in mosquitoes. Here, we report a global overview of tissue-specific miRNAs (miRNA) expression during the PV and PBM phases and identify miRNAs regulated during PV to PBM transition. The observed coordinated changes in the expression levels of a set of miRNAs in the energy-storing tissues suggest a role in the regulation of blood meal-induced metabolic changes.
蚊子传播人类疟原虫,这种寄生虫导致了全球大部分致命的疟疾病例。吸血的生活方式决定了蚊子的生殖生物学特性,疟原虫利用这种特性进行自身的有性生殖和传播。蚊子生殖周期的两个主要阶段,即卵黄发生前期(PV)和吸血后(PBM),决定了其传播疟疾的能力。这些阶段之间的转变受到严格协调,以确保蚊子组织之间的内稳态和成功繁殖。其中一层控制由微小RNA(miRNA)提供,它们是蚊子中众所周知的血餐消化和卵子发育的调节因子。在这里,我们报告了PV和PBM阶段组织特异性miRNA表达的全局概况,并鉴定了在PV到PBM转变过程中受调节的miRNA。在储能组织中观察到的一组miRNA表达水平的协调变化表明它们在调节血餐诱导的代谢变化中发挥作用。
