Oxidative stress plays a key role in the regulation and control of cell survival.Reactive oxygen species (ROS) contribute to apoptosis in mammalian cells by mediating oxidative stress.We previously id
BmNPV is a serious viral pathogen of silkworm,and no drug or specific protection is available at present time.Although most genes’ function of BmNPV was depicted in recent years,knowledge on BmNPV ent
The silkworm,Bombyx mori,is the economically important insect domesticated more than 5000 years.Most economic traits of silkworm attentioned by the breeders are quantitative traits.The QTL mapping has
Silk gland cells of silkworm larvae undergo multiple endomitotic cell cycles for the synthesis of silk proteins in the spinning phase.Here we analyze the endomitotic DNA synthesis of the silk gland ce
呋喃虫酰肼是具有拟蜕皮激素作用的双酰肼类昆虫生长调节剂。该药剂的使用浓度对3 龄家蚕无熏蒸毒性,有一定触杀毒性,有强烈胃毒作用。桑叶蘸该药剂给家蚕添食致家蚕中毒死亡的LC50 5 龄＞4 龄,至眠时或结茧时的LC505 龄＜4龄＜3 龄,LC10 以下浓度药剂对3、4 龄家蚕生长发育未表现蜕皮激素作用,对熟蚕上蔟时间未见影响；用喷洒该药剂一定时间后的桑树上的叶子喂蚕,表现出明显的蜕皮激素类药物症状
The insulin signal pathway plays an important role in regulating cell growth and cell proliferation.The purpose of this study was to investigate whether the insulin signal pathway is involved in endom
肠道上皮是昆虫接触微生物最为频繁的组织，细胞的Gαq-PLCβ-Ca2+-DUOX-ROS信号通路对果蝇肠道内ROS表达进行调控，其在保护肠道正常微生物群落和控制病原微生物侵染中起到关键的作用.基于家蚕全基因组数据，鉴定获得家蚕DUOX-ROS信号通路的重要成员BmGαq、BmPLCβ1、BmPLCβ4和BmDUOX.通过微生物经口侵染家蚕的实验，表明家蚕ROS信号通路成员可以被家蚕微孢子虫诱导上
10-Hydroxycamptothecin (HCPT),a plant alkaloid separated from camptotheca acuminate,is known to be effective at inducing apoptosis of tumor cells; however,the mechanism is still unclear.In this study,
The identified characteristic of Fork head box (Fox) genes is the Fork head domain,a winged deoxyribonucleic acid (DNA)-binding domain,which indicated these genes encoding transcription factors.Invert
Body color and reproduction has always been the extremely two important issues in development and evolution biology.There is a typical body color and development mutant,Speckled(Spc),in silkworm.This
