主 题：Ornithodoros moubata target of rapamycin ticks vitellogenesis vitellogenin
摘 要：Initiation of vitellogenesis by blood feeding is essential for egg maturation in *** derived from the blood meal are utilized by female ticks to synthesize the yolk protein precursor vitellogenin(Vg).Engorged Ornithodoros moubata ticks can synthesize Vg whether mated or virgin,thus *** is an excellent model for studying the relative roles of blood feeding and mating in tick *** of rapamycin into engorged *** resulted in a reduction of ovarian growth and yolk accumulation in the oocytes of mated *** expression in the midgut and fat body and protein concentrations in the hemolymph significantly decreased in mated ticks after injection with rapamycin,indicating that inhibition of the nutrient-sensing target of rapamycin(TOR)pathway disrupts egg maturation at the levels of Vg expression and *** results suggest that the TOR-signaling pathway induces vitellogenesis in response to nutritional stimulation after a blood meal in *** and is functionally independent of the mating-induced pathway.
