In previous research, we demonstrated that whiteflies from the Aleyrodidae family (e.g., <em>Bemisia tabaci</em>), mosquitoes from the Culicinae subfamily (e.g., <em>Aedes aegypti</em>), and flies of Sciaroidea superfamily (e.g., <em>Contarinia nasturtii</em>) acquired these genes via three independent horizontal gene transfer events. The temporal expression profiles analyzed in mosquitoes and flies are consistent with the expected for immune effector molecules of insects. Notably, in <em>A. aegypti</em>, we found that these genes contribute to immunity. In whiteflies, codon analysis suggests that RIP genes have evolved under the influence of natural selection. Public transcriptomic experiments have shown that these genes are expressed in the adult stage of <em>B. tabaci</em>. Despite computational findings supporting RIP genes functionality in whiteflies, no experimental studies have been conducted. Furthermore, there is currently no publicly available RNA-seq data evaluating gene expression throughout ontogeny in the Aleyrodidae family. In this work, we experimentally demonstrated the presence of these foreign genes in the genome of <em>Trialeurodes vaporariorum</em>. We quantified their expression across the life cycle stages of this species and analyzed their untranslated regions. The results obtained contribute to a deeper understanding of the biological roles that these ribotoxin encoding genes may play in whiteflies and other insects.</div></div>","PeriodicalId":12499,"journal":{"name":"Gene","volume":"948 ","pages":"Article 149356"},"PeriodicalIF":2.6,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143508353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lactylation, a recently characterized posttranslational modification (PTM), has been identified in histone and nonhistone proteins. Compelling evidence suggests that this lactate-related epigenetic modification potently regulates gene expression under physiological and pathological conditions. However, the distribution of this histone modification in the testis remains largely unknown. In this study, we investigated the expression dynamics of histone acetyltransferases (HATs), histone deacetylases (HDACs), and the lactate-regulating enzyme hexokinase 2 (HK2), and examined the cellular distribution of several types of histone lactylation, which have been identified as important for transcription and chromatin accessibility, in mouse testes during critical postnatal developmental stages. The results revealed that the expression levels of the lactylation-associated transcripts were developmentally regulated and that the histone lactylation, including H3K9la, H3K12la and H4K18la were present in spermatogenic and Sertoli cells at postnatal days (PD) 0, 6, 21, and 60. However, signals for H3K5la and H3K14la were not detected in gonocytes at PD0 and signal for H3K14la was not detected in mature Sertoli cells or spermatogonia of adult testes. Furthermore, a lack of lactate dehydrogenase a (<em>Ldha</em>) in Sertoli cells impacted the localization of several histone lactylation modifications in spermatogenic cells. Notably, H4K12la was specifically detected in zygotene and diplotene spermatocytes in the control testis, whereas it was present mainly in spermatogonia of <em>Lhda</em> Sertoli cell conditional knockout testis (<em>Ldha</em>-cKO).

Despite its significance, the ALA content in peanut seeds-a major global oilseed crop-is notably low. This study employed bioinformatics analysis, tissue expression, and promoter function evaluations to investigate <em>AhFAD3</em>, which encodes the microsomal omega-3 fatty acid desaturase that is directly responsible for ALA accumulation through converting linoleic acid (LA) to ALA. We identified the active <em>AhFAD3</em> gene, <em>AhFAD3-A01</em>, with the functional protein encoded by <em>AhFAD3-A01</em> localized in the endoplasmic reticulum (ER) and found to be pivotal in ALA synthesis in seeds. The low expression of <em>AhFAD3</em> genes during the late stages of seed development, coupled with the specific activation by only <em>AhFAD3-A01</em> and <em>AhFAD3-B01</em> promoters in seeds, results in the low ALA levels in mature peanut seeds. To enhance ALA content, the constitutive promoter CaMV35S and the seed-specific promoter P<em>_AhWRI1</em> were utilized to overexpress <em>AhFAD3-A01</em> in Arabidopsis and peanut. While the expression level of <em>AhFAD3-A01</em> in P<em>_AhWRI1</em>::<em>AhFAD3-A01</em> transgenic Arabidopsis remained unchanged, it significantly increased under the CaMV35S::<em>AhFAD3-A01</em> configuration, leading to an over a 40 % increase in ALA content of in T₄ generation seeds, indicating that P<em>_AhWRI1</em> was unable to drive <em>AhFAD3</em> overexpression in Arabidopsis.

This investigation aimed to elucidate the association between ZNF-76 gene expression, protein levels, and rs10947540 SNP in a cohort of Egyptian SLE patients. One hundred healthy controls and one hundred SLE patients were recruited.

Our results revealed downregulation of ZNF-76 mRNA expression in approximately 75% of SLE patients, with a significant decrease (0.23-fold) in median expression compared to controls. Furthermore, SLE patients exhibited a higher prevalence of high-risk TT genotype and demonstrably lower serum ZNF-76 protein levels.
