This project investigates how genetic and pharmacological perturbations of actin and actin-binding proteins influence global gene expression and aging phenotypes in Caenorhabditis elegans. Whole-animal RNA interference was used to knock down key actin regulatory genes, including arx-2 (Arp2/3 complex), unc-60 (cofilin), and lev-11 (tropomyosin). Here Bulk RNA sequencing was performed to assess transcriptional responses to actin cytoskeletal disruption using genetic knockdown (RNAi) of actin-binding proteins and actin de/stabilizing molecules. These datasets capture transcriptomic signatures associated with actin dysfunction, aging trajectories, and stress responses, and provide a resource for exploring the molecular links between cytoskeletal integrity and longevity regulation.</description><repository>biostudies-arrayexpress</repository><sample_protocol>Library Construction - Library construction was performed by Novogene using their standard pipeline.</sample_protocol><sample_protocol>Nucleic Acid Extraction - After transfering to 1 mL of TRIzol Reagent, animals are subjected to three freeze/thaw cycles between liquid nitrogen and a 37°C bead bath, with 30 s vortexing between cycles. Following the final thaw, chloroform was added at a 1:5 ratio (chloroform:TRIzol), and RNA was separated by centrifugation in heavy gel phase‐lock tubes (VWR, 10847‐802). The aqueous phase was combined 1:1 with isopropanol, and purification was performed with a QuantaBio Extracta Plus RNA kit (95214) per the manufacturer's instructions.</sample_protocol><sample_protocol>Sample Collection - After bleaching and L1 arrest, worms were grown at 22 °C for 72, 96, or 192 hours to obtain day 1, day 2, and day 6 adult animals, respectively. For each condition, approximately 1,000 worms were collected using M9 buffer and transferred into 1 mL of TRIzol Reagent for RNA extraction.</sample_protocol><sample_protocol>Sequencing - RNA-sequencing was performed by Novogene using their standard pipeline.</sample_protocol><figure_sub>Organization</figure_sub><figure_sub>MINSEQE Score</figure_sub><figure_sub>Assays and Data</figure_sub><figure_sub>Processed Data</figure_sub><figure_sub>MAGE-TAB Files</figure_sub><data_protocol>Data Transformation - Pre-processing to trim low-quality reads and adaptor sequences was performed with Trim Galore v0.6.7-1. Reads were aligned to the WBcel235 genome using STAR‐2.7.3a, and a raw count matrix was generated using Subread v2.0.3.  Differential expression was calculated with DESeq2 and sva v3.54.0 was employed to correct for batch effects and non-biological sources of variation.</data_protocol><omics_type>Unknown</omics_type><omics_type>Transcriptomics</omics_type><omics_type>Genomics</omics_type><omics_type>Proteomics</omics_type><instrument_platform>Illumina NovaSeq 6000</instrument_platform><study_type>RNA-seq of coding RNA</study_type><species>Caenorhabditis elegans</species><pubmed_authors>Ryo Higuchi-Sanabria</pubmed_authors></additional><is_claimable>false</is_claimable><name>Form and function of actin impacts actin health and aging.RNAseq</name><description>The actin cytoskeleton is a highly conserved structural network that supports diverse cellular processes, but its contribution to organismal aging is not well understood.
