As a member of the heat shock family, Hsp60 significantly influences viral proliferation. However, limited research is available on its role in the proliferation of entomopathogenic baculoviruses, particularly <i>Bombyx mori</i> nucleopolyhedrovirus (BmNPV). Our previous proteomics results showed a significant decrease of Hsp60 acetylation levels after BmNPV infection. To investigate the impact of Hsp60 deacetylation on viral proliferation, site-direct mutagenesis was performed to generate a deacetylated (K/R) mimic of Hsp60. We found that the acetylation level of lysine 362 (K362) decreased after BmNPV challenge. Furthermore, overexpression of deacetylation-mimicking Hsp60 reduced the chaperone activity of Hsp60, leading to impaired mitochondrial function, including increased reactive oxygen species (ROS) levels, decreased mitochondrial membrane potential, and reduced substrate protein Manganese-containing superoxide dismutase (Mn-SOD) activities, ultimately leading to inhibition of viral proliferation. This study establishes lysine 362 acetylation of Hsp60 as a model for Posttranslational modifications induced by host-virus interactions, providing new insights into potential antiviral strategies.</p></div>","PeriodicalId":8281,"journal":{"name":"Archives of Insect Biochemistry and Physiology","volume":"118 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, insects play critical roles in ecosystems as pollinators, decomposers, and prey and serve as vectors of diseases that impact human health and agriculture. Exploring their physiological mechanisms—from respiration and digestion to sensory perception and reproduction— provides valuable insights into their adaptability and survival strategies. Moreover, insect biochemistry offers a window into unique metabolic pathways, enzyme functions, and molecular interactions that often differ significantly from those of vertebrates. This knowledge not only enhances our understanding of biodiversity and evolution but also informs the development of innovative approaches in pest management, biotechnology, and even biomedical research. By delving into the complex interplay of physiology and biochemistry in insects, we can uncover strategies to address global challenges while appreciating the marvels of these remarkable organisms.&lt;/p&gt;&lt;p&gt;The idea for this special issue (SI) was developed at the “Second International Molecular Plant Protection Congress (IMPPC2023- https://www.imppc2023.org/)” that was organized in Bursa, Türkiye, on May 15-18, 2023, with the theme “Innovations in Plant Protection.” IMPPC2023 hosted 782 participants from 24 countries, while 79 keynote speakers delivered invited talks. 41 global and local agriculture and biotechnology companies presented their products in the exhibition hall. The congress was a great success, which encouraged us to compile this SI “Recent Insights into Insect Physiology and Biochemistry.”&lt;/p&gt;&lt;p&gt;The current SI includes 11 research articles. Both keynote speakers of the IMPPC2023 and several other experts were invited to contribute to this issue. The SI focused on the recent fundamental &amp; molecular &amp; biochemical insights into insect physiological systems' structure and operation. Toxicological studies, as well as studies on microbial control and insect pathology, were also welcomed. As the development of alternatives to chemical insecticides in pest management has been an attractive research topic, such novel insecticidal molecules and their impact on insect physiological systems were also included.&lt;/p&gt;&lt;p&gt;In conclusion, this SI has explored the dynamic and multifaceted field of insect physiology and biochemistry, showcasing cutting-edge research and its applications in pest management, agriculture, and beyond.

Current control methods using broad-spectrum insecticides are largely ineffective due to resistance development and their adverse effects on nontarget organisms, necessitating novel strategies. This study integrates proteomics and transcriptomics data to explore the molecular landscape of RPW and identify pathways for targeted pest management.

These proteins underwent pathway enrichment analysis, mapping to 39 enriched pathways (<i>p-value</i> and an FDR of &lt; 0.01). Among these, two pathways involving three key enzymes were highlighted as high-potential targets for developing insect-specific insecticides and diet-specific control strategies.

In our previous work, the entomopathogenic <i>Metarhizium anisopliae</i> JEF-197 was effective in controlling JPSB adults. However some of JPSB adults survived well even against the fungal treatment. Now here in this work, we analyzed the transcriptome of JEF-197 from the fungus-treated JPSB adults which still survived in 8 days after the treatment. The day was determined based on the lethal time 50 (LT₅₀) in our previous study. As a control, JEF-197 was cultured on 1/4SDA for 8 days. The plate-cultured JEF-197 transcripts were used for building-up an index in the abundance analysis using kallisto to investigate the gene regulation. Additionally, transcripts from the JEF-197-treated PSB were analyzed to find possible fungal transcripts to enlarge the index of abundance analysis. In the following differentially expressed gene (DEG) analysis, most JEF-197 transcripts showed significant down-regulations in JPSB adults 8 days after treatment, which were presented as clustering heatmap, PCA, MA and Volcano plots. The GO enrichment analysis showed similar results, in which most of pathways were significantly suppressed. Metabolic and biosynthesis metabolisms were most dominantly downregulated pathways. Particularly, many genes of glucose metabolisms were significantly suppressed, including genes for glycolysis, TCA, ATP &amp; nucleotide synthesis, and glycogen &amp; chitin production. This work suggests that JEF-197 lost its own glucose metabolism in the survived JPSB adults, and the survival could be involved in the active and continuous host defense mechanisms. It gives us questions what factors would be involved in the different response of individual to the fungal treatment and what happens if live and dead hosts were pooled in RNA-sequencing.</p></div>","PeriodicalId":8281,"journal":{"name":"Archives of Insect Biochemistry and Physiology","volume":"118 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While our current understanding has mainly focused on cellular signals and phenotypic shifts occurring at a global scale during diapause, information on tissue-specific transcriptomic changes remains limited. This knowledge gap is a major challenge in interpreting the regulatory mechanisms at the tissue level. To address this, the present work utilized RNA-seq technology to investigate the transcriptional changes in the head that house the brain and crucial endocrinal organs such as corpora allata. We obtained RNA samples from the heads of diapausing and nondiapausing female mosquitoes at two specific time intervals, ZT0 and ZT16, and then subjected them to sequencing. Our results revealed differences in differentially expressed genes between diapause and non-diapause at ZT0 and ZT16, highlighting the phenotypic and diel variations in gene expression. We also selected twelve genes associated with the diapause phenotype and examined the transcript abundance at six different time points over 24 h. qRT-PCR analysis showed similar up- and downregulation of transcripts between the diapause and nondiapause phenotypes thus validating the results of RNA-seq. In summary, our study identified new genes with phenotypic and diel differentiation in their expression, potentially linking photoperiod to seasonal reproductive dormancy in insects.
