- Mosquitoes, especially Aedes aegypti, transmit major human diseases such as dengue, Zika, and chikungunya. Epigenetic regulation, including histone acetylation, plays a key role in controlling Ae. aegypti development. However, the specific roles of histone acetyltransferases (HATs) and N-terminal acetyltransferases (NATs) in mosquito development remain poorly understood. In this study, we investigated 25 HAT/NAT genes functions by knocking them down via feeding Ae. aegypti larvae with dsRNA nanoformulations. Gene expression analysis confirmed that target gene expression was reduced by more than 50% in dsRNA-treated larvae. Knocking down 18 of these HATs/NATs resulted in over 50% mortality. Silencing KAT7, NATSCAN, NAT9, ATAT1, and TADA3 caused larval death, whereas knockdown of NAA80, NAA-Eco, GNPNAT1, HAT-B, and MCM3AP led to pupal mortality. Knockdown of NATSCAN, NF, TFIID, GNPNAT1, and NAA16 resulted in molting and metamorphic defects, characterized by untanned cuticles and failure to complete successful larval-pupal metamorphosis. Phylogenetic analysis of conserved domains of HATs and NATs revealed that evolutionarily conserved members cluster into distinct clades associated with larval- or pupal-specific functions. Developmental expression analysis showed stage-specific expression of these genes. Further, stage-specific expression analysis revealed that dynamic expression patterns of KAT7, RNACAT, NAT9, and NF are linked to larval growth and pupal metamorphosis. Treatment with 20-hydroxyecdysone (20E) or an ecdysone agonist increased mRNA levels of NAA30,NAA40,NAT9, and GNAT8, indicating hormonal control of histone acetylation. Ecdysone-induced HATs/NATs regulated the expression of primary ecdysone response genes: E75A and E93. These results demonstrate that HATs/NATs play key roles in Ae. aegypti development and therefore could serve as potential targets for mosquito control. - Source: PubMed

Gaddelapati Sharath ChandraPalli Subba Reddy - Histone acetyltransferases (HATs) catalyse the addition of acetyl groups to histones and other proteins. In contrast, histone deacetylases remove acetyl groups from core histones, and the activity of these enzymes maintains the acetylation levels of these proteins. Histone acetylation levels influence chromatin accessibility and gene expression and regulate many biological processes, including development and reproduction. Recent reports suggest that some N-terminal acetyltransferases (NATs) also regulate gene expression. We identified 29 HAT and NAT genes in the red flour beetle, Tribolium castaneum, and studied their functions in female reproduction using RNA interference (RNAi). Knockdown of seven out of 13 HAT genes (N-acetyltransferase ESCO2) (ESCO1/2), Elongator complex protein 3 (ELP3), Histone acetyltransferase type B catalytic subunit 1 (HAT1), Transcription initiation factor TFIID subunit 1 (TAF1), Protein x-mas-2 (MCM3AP), Histone acetyltransferase Tip60 (KAT5), and Cysteine-rich protein 2-binding protein (KAT14) and 12 out of 16 NAT genes Probable glucosamine 6-phosphate N-acetyltransferase (GNPNAT1), N-alpha-acetyltransferase 10 (NAA10), N-alpha-acetyltransferase 20 (NAA20), N-alpha-acetyltransferase 30 (NAA30), N-alpha-acetyltransferase 40 (NAA40), N-alpha-acetyltransferase 60 (NAA60), N-acetyltransferase 6 (NAA80), RNA cytidine acetyltransferase (NAT10), Diamine acetyltransferase 2 (SATL1), N(alpha)-acetyltransferase 16 (NAA16), Phagocyte signalling-impaired protein (NAA25), N(alpha)-acetyltransferase 35 (NAA35) caused a significant reduction in eggs laid by females compared to the eggs laid by control females injected with dsGFP. Also, knockdown of nine (KAT5, ATAT1, ELP3, HAT1, KAT8A, NAA10, NAA20, GNPNAT1 and TAF1) HAT/NAT genes caused a significant decrease in egg hatching. Parental RNAi of ATAT1 and KAT8 blocked embryogenesis. These data suggest that the acetylation of proteins plays an important role in female reproduction and embryogenesis. - Source: PubMed

Sengodan KarthiPalli Subba Reddy - During the growth and development of animals, there is an interaction between the gut microbiota and the host genotype. The host genotype can regulate the microbiota, and in turn, the microbiota can influence host gene expression, thereby affecting the animal's production performance. This study explored the dynamic interplay between the gut microbiota and host gene expression in body weight variation in Dagu chicken, an indigenous poultry genetic resource in China. We characterized mucosa-associated microbiota across four gastrointestinal segments (duodenum, jejunum, ileum, cecum) and ileocecal chyme microbiota in 12-week-old Dagu chickens stratified by divergent body weight phenotypes, while simultaneously quantifying region-specific intestinal epithelial transcriptional regulation. 16S rDNA sequencing was employed to identify Firmicutes as the predominant bacterial phylum, with notable differences in the abundance of specific genera (e.g., Ligilactobacillus and Lactobacillus) being observed between the high- or low-body-weight groups. Enhanced biosynthesis pathways were functionally predicted in heavier roosters, whereas reduced nutrient metabolism pathways were contrasted. A conserved functional concordance was observed between regionally predominant differential microbiota and the physiological specialization of corresponding intestinal niches. Functional analysis revealed that the high-body-weight group demonstrated superior capabilities in microbial biosynthesis, whereas the low-body-weight group exhibited enhanced microbial metabolic activity. NAA80 was identified as the common differentially expressed gene across all intestinal epithelial tissues. The Gene Ontology and KEGG pathway analyses revealed elevated nutrient absorption efficiency in the high-body-weight group, while the low-body-weight group demonstrated accelerated cellular renewal rates and shorter cycles. Correlation analysis identified significant associations between gut microbiota and host genes expression profiles, with the majority of correlations being positive. These results suggest a coordinated interaction between microbial communities and host genetic regulation, potentially driving phenotypic differences in body weight performance. - Source: PubMed

Li XiaohanHan XueruYan HuanZhu HongyanWang HongcaiLi DeshengTian YuminSu Yuhong - Histone acetylation levels maintained by histone acetyltransferases (HATs) and histone deacetylases play important roles in maintaining local chromatin accessibility and expression of genes that regulate many biological processes, including development and reproduction. N-terminal acetylation of proteins catalyzed by N-terminal acetyltransferases (NATs) also regulates gene expression. We identified 25 HATs/NATs genes in the yellow fever mosquito, Aedes aegypti, and investigated their function in female reproduction using RNA interference (RNAi). Among the HATs/NATs studied, the knockdown of AANAT1 (Arylamine N-acetyltransferase), NAA40 (N-alpha-acetyltransferase 40), NAA80 (N-alpha-acetyltransferase 80), KAT7 (Histone lysine acetyltransferase 7), ACNAT (Acyl-CoA N-acyltransferase), and MCM3AP (Minichromosome maintenance complex component 3 associated protein) significantly reduced egg laying and caused severe problems in oocyte development compared to that in control insects injected with dsGFP. Gene expression analysis using RT-qPCR revealed that vitellogenin and its receptor genes are downregulated in mosquitoes injected with dsAANAT1, dsNAA40, dsNAA80, dsKAT7, dsACNAT, and dsMCM3AP compared to that in control animals. Also, the knockdown of HATs/NATs genes ATAT1 (Alpha-tubulin N-acetyltransferase 1), AANAT1, TAFIID (Transcription initiation factor TFIID subunit 1), HATB (Histone acetyltransferase type B) and NAT9 (N-acetyltransferase 9) decreased more than 50% egg hatch by blocking embryonic development. These results suggest that the acetylation of proteins, especially histones mediated by NATs and HATs, plays an important role in regulating female reproduction and embryonic development of Ae. aegypti. - Source: PubMed
Balasubramani SundararajanPalli Subba Reddy - Actin is a critical component of the eukaryotic cytoskeleton. In animals, actins undergo unique N-terminal processing by dedicated enzymes resulting in mature acidic and acetylated forms. The final step, N-terminal acetylation, is catalyzed by NAA80 in humans. N-terminal acetylation of actin is crucial for maintaining normal cytoskeletal dynamics and cell motility in human cell lines. However, the physiological impact of actin N-terminal acetylation remains to be fully understood. We developed a zebrafish knockout model and demonstrated that Naa80 acetylates both muscle and non-muscle actins in vivo. Assays with purified Naa80 revealed a preference for acetylating actin N-termini. Zebrafish lacking actin N-terminal acetylation exhibited normal development, morphology, and behavior. In contrast, humans with pathogenic actin variants can present with hypotonia and hearing impairment. Whereas zebrafish lacking showed no obvious muscle defects or abnormalities, we observed abnormal inner ear development, small otoliths, and impaired response to sound. In conclusion, we have established that zebrafish Naa80 N-terminally acetylates actins in vitro and in vivo, and that actin N-terminal acetylation is essential for normal hearing. - Source: PubMed
