The nuclear receptors and are highly conserved and function to regulate molting and reproduction in both hemimetabolous and holometabolous insects. However, their roles in are largely unknown. In the present study, we discover that and are activated in the nymph stages by ecdysone signaling. Transcription disruption of and expression prevents nymph ecdysis and metamorphosis, which leads to abnormal appearance, malformed ovaries, and lethal phenotypes. In addition, we demonstrate that and regulate molting and reproduction by interacting with the intrinsic 20E and JH signaling pathways. Our work offers a deep insight into the action mechanisms of and in insects. Moreover, and could properly be exploited as potential target genes for developing RNAi-based pesticides to control .

The effect of thermal stress on the X-organ/sinus gland proteome of the estuarine blue crab Callinectes sapidus during the intermolt and premolt stages.

J Proteomics

Survival of brachyuran crabs is temperature-dependent and thermal stress promotes changes during molting. We aimed to decipher the impact of thermal stresses on the X-organ/sinus gland (XO/SG) complex, a temperature-sensitive neuroendocrine tissue involved in the molting regulation of Callinectes sapidus during the intermolt and premolt phases. We employed a proteogenomic approach using specimens subjected to control (24 °C), cold (19 °C), and heat (29 °C) temperatures.

Exploring the metabolic patterns and response mechanisms of bile acids during fasting: A study with poultry as an example.

Fasting is beneficial to alleviate fatty liver, lose weight and improve reproductive function. However, previous studies have shown that, during fasting, disorders of bile acid metabolism were strongly associated with intestinal inflammation. The physiological and biochemical parameters and gene expression of multiple tissues of chickens at every critical time node were measured by ELISA and qPCR.

Transcriptomic insight into the underlying mechanism of induced molting on reproductive remodeling, performance and egg quality in laying hen.

Article Synopsis
  • The study examined how fasting during molting affects the reproductive system and egg quality in laying hens, particularly focusing on reproductive remodeling mechanisms.
  • Two hundred and forty 380-day-old Jingfen No. 6 hens were divided into four experimental groups to analyze changes across different molting stages: pre-molt, molt, recovery, and peak-laying.
  • Key findings showed that fasting led to oviduct atrophy, loss of large follicles in ovaries, and hormonal changes, while transcriptomic analysis identified important genes influencing reproductive function and egg quality improvements post-molt.

In this study, we investigated the regulatory roles of the () gene in the reproductive process of female . Its total cDNA length was 1848 bp, encoding for 460 amino acids. It contained conserved domains typical of epoxide hydrolases, such as the Abhydrolase family domain, the EHN epoxide hydrolase superfamily domain, and the "WWG" and "HGWP" motifs.

Cuticular nitrogen economy during development in the cockroach Cryptocercus punctulatus and the termite Neotermes jouteli.

J Insect Physiol

Department of Entomology, VA Tech, Blacksburg, VA, 24061-0319, United States.

The role of nitrogen during insect development and reproduction is key in the success of a species, and is of primary importance in wood feeding taxa. Based on comparison of xylophagous, one-piece termites to the termite sister group, subsocial wood-feeding cockroaches in the genus Cryptocercus, it has been proposed that the evolution of termite eusociality involved a fundamental shift in nitrogen allocation strategies. Cryptocercus exhibits a nitrogen storage economy, with individuals gradually increasing in size and cuticular density over a years-long developmental period.
