Comparative transcriptomic and metabolomics analysis of ovary in Nilaparvata lugens after trehalase inhibition by Yongkang Liu, Fan Yang, Sijing Wan, Xianzhong Wang, Liwen Guan, Yan Li, Caidi Xu, Binghua Xie, Shigui Wang, Xiao-Ling Tan, Bin Tang

“…The overlapping DEGs were implicated in various biological processes, including protein metabolism, fatty acid metabolism, AMPK signaling, mTOR signaling, insulin/insulin-like growth factor signaling (IIS), the tricarboxylic acid (TCA) cycle, oxidative phosphorylation, and the cellular process of meiosis in oocytes. These results suggest that the inhibition of TRE expression may lead to alterations in ovarian nutrient and energy metabolism by modulating glucose transport and affecting amino acid metabolic pathways. …”
