AI Article Synopsis
- - The study investigates how the growth stages of maize plants affect the migration and residency behavior of a significant agricultural pest, highlighting a lack of clarity in previous research.
- - Results reveal that pests feeding on maize seeds show characteristics favoring migration, such as longer adult stages and more developed flight muscles, while those feeding on leaves exhibit traits associated with residency like faster egg maturation.
- - The findings underscore the importance of the nutritional content of host plants in influencing the pest's behavior and life cycle, providing valuable insights for understanding its invasion patterns.
Article Abstract
is a significant agricultural pest that migrates annually based on the growth stages of its host plants. However, the role of host plant growth stages in the residency or migration of remains unclear. We allowed to feed on maize leaves and seeds, and results showed that maize seeds had higher amino acids, carbohydrates, and triglyceride (TG). that fed on seeds had longer adult stages; larger wings; higher TG, juvenile hormone II (JH II), and JH III; and more developed flight muscles, indicating tendencies toward migration. Interestingly, maize leaves were richer in sterols. that fed on leaves exhibited longer larval stages, higher 20-hydroxyecdysone (20E) and JH I, faster egg maturation, and earlier oviposition, suggesting tendencies toward residency. These findings suggest that the nutritional composition of host plants influences for migration or reproduction, offering new insights into its invasion and establishment patterns.

Background: Tumor microenvironment (TME) plays a crucial role in tumor growth and metastasis. Exploring biomarkers that are significantly associated with TME can help guide individualized treatment of patients.
Methods: We analyzed the expression and survival of P4HB in pan-cancer through the TCGA database, and verified the protein level of P4HB by the HPA database.

Histone lysine-specific demethylase 1 (LSD1) is overexpressed in various solid and hematological tumors, suggesting its potential as a therapeutic target, but there are currently no LSD1 inhibitors available on the market. In this study we employed a computer-guided approach to identify novel LSD1/EGFR dual inhibitors as a potential therapeutic agent for non-small cell lung cancer. Through a multi-stage virtual screening approach, we found L-1 and L-6, two compounds with unique scaffolds that effectively inhibit LSD1 with IC values of 6.

Background: This study aimed to investigate the prognostic impact of lymph node metastasis (LNM) on patients with colorectal cancer liver metastasis (CRLM) and elucidate the underlying immune mechanisms using multiomics profiling.
Methods: We enrolled patients with CRLM from the US Surveillance, Epidemiology, and End Results (SEER) cohort and a multicenter Chinese cohort, integrating bulk RNA sequencing, single-cell RNA sequencing and proteomics data. The cancer-specific survival (CSS) and immune profiles of the tumor-draining lymph nodes (TDLNs), primary tumors and liver metastasis were compared between patients with and without LNM.

Background And Objective: Gastric cancer (GC) remains a prevalent and preventable disease, yet accurate early diagnostic methods are lacking. Exosome non-coding RNAs (ncRNAs), a type of liquid biopsy, have emerged as promising diagnostic biomarkers for various tumours. This study aimed to identify a serum exosome ncRNA feature for enhancing GC diagnosis.

Cold stress is one of the most serious abiotic stresses that affects the growth and yield in rice. However, the molecular mechanism by which abscisic acid (ABA) regulates plant cold stress tolerance is not yet clear. In this study, we identified a member of the OsNCED (9-cis-epoxycarotenoid dioxygenase) gene family, OsNCED5, which confers cold stress tolerance in rice.
