VDJ: Single-cell RNA sequencing of human steady-state immune cells from the lamina propria of colon and matching mesenteric lymph nodes

ABSTRACT: The human colon contains an extensively diverse microbial ecosystem and one of the most numerous communities of immune cells. Studies have highlighted dynamic crosstalk between immune cells and commensals. While studies have demonstrated increasing diversity of microbiota from stomach to stool, whether and how immune cell heterogeneity and microbiota diversity change across the colon is undefined. Furthermore, whether these changes are co-depended in the healthy colon is unknown. Here, tissue samples are collected from caecum, transverse colon, sigmoid colon and mLN of cadaveric donors by the Cambridge Biorepository of Translational Medicine (CBTM). We use single cell RNA sequencing (10X genomics) to assess the dynamics of immune cell populations across the colon and in matching lymph nodes. Associated microbiome 16S sequencing data is available.

The human gastrointestinal tract through space and time- Adult GEX

Project description:Using single-cell RNAseq (scRNAseq) and paired VDJ analysis, we create the first comprehensive cell atlas of the healthy developing, paediatric and adult human gut, including 347,980 cells from up to 10 distinct anatomical sites. We use this data to trace the cellular composition of the gut throughout life, define novel cell markers and cell-cell interactions. We find four neuronal cell populations in the developing enteric nervous system, with expression patterns indicative of irritable bowel syndrome and Hirschsprung’s disease, and identify key cell players and communication networks initiating lymphoid structure formation in early human development.

Spatial transcriptomic reference of the endometrium and myometrium of women in reproductive age

Project description:Human uterine samples were analysed using Visium technology (10X Genomics) to generate a cellular 2D map of the endometrium to study its temporal and spatial changes across the menstrual cycle. Dataset comprises 4 samples from two women in their reproductive age.

All exon array expression data in normal colon and primary colon cancer lines [expression]

Project description:Cancer is characterized by gene expression aberrations. Studies have largely focused on coding sequences and promoters, despite the fact that distal regulatory elements play a central role in controlling transcription patterns. Here we utilize the histone mark H3K4me1 to analyze gain and loss of enhancer activity genome wide in primary colon cancer lines relative to normal colon crypts. We identified thousands of variant enhancer loci (VELs) that comprise a signature that is robustly predictive of the in vivo colon cancer transcriptome. Furthermore, VELs are enriched in haplotype blocks containing colon cancer genetic risk variants, implicating these genomic regions in colon cancer pathogenesis. We propose that reproducible changes in the epigenome at enhancer elements drive a unique transcriptional program to promote colon carcinogenesis. We used gene expression profiles to assess correlations between the colon cancer epigenome and transcriptional activity. RNA from normal colon epithelial crypt controls and primary colon cancer cell lines was hybridized to Affymetrix All Exon Human ST 1.0 microarrays.

Single-cell RNA-seq of Endometrial Superficial biopsies and full depth uterine tissue from organ donors

Project description:We performed single-cell RNA-sequencing to create a cell census of the human endometrium, which is the mucosal lining of the uterus that undergoes dynamic changes throughout the menstrual cycle. We integrated cells that were obtained from 3 superficial biopsies to selected samples that originated from 2 organ donors; this allowed a better representation of cell type diversity found within the full depth of the endometrium.

Sarcomeric Proteoform Landscape in Ischemic Cardiomyopathy Defined by Top-down Proteomics

Project description:In ischemic cardiomyopathy (ICM), left ventricular systolic dysfunction leads to reduced blood flow and oxygen supply to the heart. Alterations in sarcomeric protein function and expression play prominent roles in the onset and progression of cardiomyopathies; however, the molecular mechanisms underlying ICM remain poorly defined. Herein, we have implemented a top-down liquid chromatography (LC)-mass spectrometry (MS)-based proteomics method for the simultaneous quantification of sarcomeric protein expression and modifications in non-failing donor (n = 16) compared to end-stage failing ICM (n = 16) human cardiac tissues. Our top-down proteomics platform provided a “bird’s eye view” of proteoform families with high mass accuracy and reproducibility. In addition, quantification of post-translational modifications (PTMs) and expression reveal significant changes in various sarcomeric proteins extracted from ICM tissues. Changes include altered phosphorylation and expression of cardiac troponin I (cTnI) and enigma homolog 2 (ENH2) as well as a marked increase in muscle LIM protein (MLP) and calsarcin-1 phosphorylation in ICM hearts. Our results imply that the contractile apparatus of the sarcomere is severely dysregulated during ICM. Thus, this study is the first to uncover significant molecular changes to multiple sarcomeric proteins in end-stage ischemic heart failure patients using LC-MS-based top-down proteomics.
