Liu Y, Tao YD, Zhang LB, Wang F, Xu J, Zhang JZ, Fu DY. Blue Light Exposure Caused Large-Scale Transcriptional Changes in the Abdomen and Reduced the Reproductive Fitness of the Fall Armyworm Spodoptera frugiperda. INSECTS 2023; 15:10. [PMID: 38249016 PMCID: PMC10816951 DOI: 10.3390/insects15010010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 12/21/2023] [Accepted: 12/23/2023] [Indexed: 01/23/2024]
Abstract
In the present study, we found that blue light stress negatively affected the development periods, body weight, survival and reproduction of Spodoptera frugiperda, and it showed a dose-dependent reaction, as longer irradiation caused severer effects. Further transcriptome analysis found blue light stress induced fast and large-scale transcriptional changes in the head, thorax and, particularly, the abdomen of female S. frugiperda adults. A functional enrichment analysis indicated that shorter durations of blue light irradiation induced the upregulation of more stress response- and defense-related genes or pathways, such as abiotic stimuli detection and response, oxidative stress, ion channels and protein-kinase-based signal pathways. In the abdomen, however, different durations of blue-light-exposure treatments all induced the downregulation of a large number genes and pathways related to cellular processes, metabolism, catalysis and reproduction, which may be a trade-off between antistress defense and other processes or a strategy to escape stressful conditions. These results indicate irradiation duration- and tissue-specific blue light stress responses and consequences, as well as suggest that the stress that results in transcriptional alterations is associated with the stress that causes a fitness reduction in S. frugiperda females.

[PMID: 37959738 PMCID: PMC10647756 DOI: 10.3390/molecules28217319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 10/22/2023] [Accepted: 10/23/2023] [Indexed: 11/15/2023] Open
Abstract
Leontopodium alpinum is a source of raw material for food additives and skin health. The purpose of this study was to investigate the application of Leontopodium alpinum callus culture extract (LACCE) to prevent blue light damage to the skin. We screened and identified the blue light-damage-protecting activities and mechanisms of ten components of LACCE, including chlorogenic acid (A), isoquercitrin (B), isochlorogenic acid A (C), cynaroside (D), syringin (E), isochlorogenic acid (F), cynarin (G), rutin (H), leontopodic acid A (I), and leontopodic acid B (J), using a novel blue light-induced human foreskin fibroblast (HFF-1) cell injury model. The study examined the cytotoxicity of ten ingredients using the cell counting kit-8 (CCK-8) assay, and selecting concentrations of 5, 10, and 20 μM for experiments with a cell viability above 65%. We explored the effects and mechanisms of action of these LACCE components in response to blue light injury using Western blotting and an enzyme-linked immunosorbent assay. We also measured ROS secretion and Ca2+ influx. Our study revealed that leontopodic acid A effectively boosted COI-1 expression, hindered MMP-1 expression, curbed ROS and Ca2+ endocytosis, and reduced OPN3 expression. These results provide theoretical support for the development of new raw materials for the pharmaceutical and skincare industries.
