Form and function of actin impacts actin health and aging - snRNAseq

ABSTRACT: The actin cytoskeleton is a highly conserved structural network that supports diverse cellular processes, but its contribution to organismal aging is not well understood. 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 single-nucleus RNA sequencing was performed to assess transcriptional responses to actin cytoskeletal disruption across tissues and age groups (Day 1 and Day 5). 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.

Single nuclei sequencing of human HFpEF (Heart Failure with reduced ejection fraction) and Mice TAC (Transaortic constriction) data

Project description:Single-cell transcriptomics has emerged as a powerful technology for understanding cardiovascular diseases, providing valuable insights into transcriptomic changes linked to heart failure, both with and without preserved ejection fraction. However, significant gaps persist in our understanding of the molecular mechanisms underlying these different types of heart failure, and we continue to seek innovative approaches to tackle the challenges posed by the increasing scale and complexity of single-cell datasets in identifying meaningful gene signatures. The integration of machine learning, particularly deep neural networks, has shown immense promise in addressing these challenges by learning transcriptional patterns from single-cell transcriptomic data, reconstructing expression profiles, and effectively classifying cells. Recent advancements in explainable artificial intelligence enhanced the interpretation of these models by attributing importance scores, such as Shapley values. However, methods for identifying differentially regulated gene contribution scores have not yet been integrated. In this study, we introduce a novel method to identify differentially explained genes (DXGs) based on importance scores derived from custom-built neural networks capable of classifying heart failure subtypes at the single-cell level. We highlight the superiority of DXGs in identifying heart failure-relevant pathways, presenting them in a format comparable to traditional differential expression analyses. Using this method, we identify novel signatures providing new insights into the molecular basis of heart failure and offering a robust foundation for future research and therapeutic exploration.

Age-dependent RGS5 loss in pericytes induces cardiac dysfunction and fibrosis in the heart

Project description:Background. Ageing is one of the main risk factors of cardiovascular disease. Pericytes are capillary-associated mural cells involved in the maintenance and stability of the vascular network. In the heart, the consequences of ageing on cardiac pericytes are unknown. Methods. In this study, we have combined single nucleus RNA sequencing and histological analysis to determine the effects of ageing on cardiac pericytes. Furthermore, we have conducted in vivo and in vitro analysis of RGS5 loss of function and finally have perfomed pericytes-fibroblasts co-culture studies to understand the effect of RGS5 loss of function in pericytes on the neighbouring fibroblasts. Results. We showed that ageing reduces the pericyte area and coverage. Single nucleus RNA sequencing analysis further revealed that the expression of the Regulator of G protein signalling 5 (Rgs5) is reduced in old cardiac pericytes. In vivo and in vitro studies showed that the deletion of RGS5 induces morphological changes and a pro-fibrotic gene expression signature characterized by the expression of different extracellular matrix components and growth factors like TGFB2 and PDGFB in pericytes. Indeed, the culture of fibroblasts with the supernatant of RGS5 deficient pericytes induced their activation characterized by the increased expression of α smooth muscle actin in a TFGβ2 dependent mechanism. Conclusions. Our results identify RGS5 as a crucial regulator of pericyte function during cardiac ageing. The deletion of RGS5 causes cardiac dysfunction and induces myocardial fibrosis, one of the hallmarks of cardiac ageing.

Single-nucleus RNA-seq of adult female and male mouse livers for sex-biased gene expression analyses

Project description:To obtain new insight into the sexual dimorphism of mammalian livers, single-nucleus RNA-seq was performed on the liver samples from two female and two male adult mice. The single-nucleus libraries were generated on the 10X Chromium Next GEM Single Cell 3ʹ platform and sequenced on Illumina NextSeq 550. We used the data to understand the heterogeneity and sex-biased gene expression of liver cell types. The data revealed significant sex differences primarily focused on hepatocytes. Specifically, from the sex-biased genes detected at the bulk tissue level, we observed that male-biased genes are more highly expressed in male hepatocytes, and female-biased genes are more highly expressed in female hepatocytes.

Spatially resolved multiomics of human cardiac niches - Multiome ATAC

Project description:Using Multiome and previously published sc/snRNA-seq data, we studied eight anatomical regions of the human heart including left and right ventricular free walls (LV and RV), left and right atria (LA and RA), left ventricular apex (AX), interventricular septum (SP), sino-atrial node (SAN) and atrioventricular node (AVN). For the first time, we profile the cells of the human cardiac conduction system, revealing their distinctive repertoire of ion channels, G-protein coupled receptors and cell-cell interactions. We map the identified cells to spatial transcriptomic data to discover cellular niches within the eight regions of the heart.

Project description:This study used droplet-based snRNA-seq to profile the gene expression of 127,371 nuclei in the developing human female and male gonads across eleven timepoints, from Carnegie Stage (CS) 14 until 21 weeks post conception (WPC). For most timepoints the study includes two biological replicates for each sex. Additionally, the study includes three technical replicates of a Klinefelter Syndrome (XXY karyotype) testis sample at 13WPC. Human prenatal tissue samples were provided by the MRC-Wellcome Trust Human Developmental Biology Resource (HDBR) and obtained from elective terminations of pregnancy. The samples were classified according to a particular Carnegie stage or week post conception based on their external physical appearance and measurements. Single-cell barcoding and library preparation were performed using Chromium Single Cell 3' Reagent Kits (v3 chemistry) and the Chromium Controller instrument (10x Genomics). Sequencing of the libraries was carried out on the Illumina NextSeq 500/550 and initial data processing was performed using Cellranger.
