Project description:Palmoplantar skin is structurally and functionally unique, but the transcriptional programs driving this specialization are unknown. Here, we exploit bulk and single-cell RNA-sequencing of human palm, sole, and hip skin to describe the distinguishing characteristics of palmoplantar and non-palmoplantar skin while also uncovering previously unappreciated differences between palmar and plantar sites. Our approach reveals downregulation of diverse immunological processes and decreased immune cell populations in palmoplantar skin, highlighting an altered immune environment in the skin of the palms and soles. Further, we identify specific palmoplantar and non-palmoplantar fibroblast populations that appear to orchestrate key differences in cell-cell communication in palm, sole, and hip. Dedicated analysis of epidermal keratinocytes highlights major differences in basal cell fraction among the three sites and validates the presence of a more differentiated, cycling basal population. Finally, our data demonstrate the existence of two spinous keratinocyte populations that constitute two parallel, site-selective epidermal differentiation trajectories. Together, these results provide a deep characterization of the highly adapted palmoplantar skin and contribute new insights into the fundamental biology of human skin.

Project description:single cell transcriptome profiling for palm and hip skin

Project description:The aim of this study was to characterise the genome-wide DNA methylation profile of osteoathritis (OA) chondrocytes from both knee and hip cartilage, providing the first comparison of DNA methylation between OA and non-OA hip cartilage, and between OA hip and OA knee cartilage. The study was performed using the Illumina Infinium HumanMethylation450 BeadChip array. Genome-wide methylation was assesed in chondrocyte DNA extracted from 23 OA hip, 73 OA knee and 21 healthy hip controls (NOF - neck of femure samples). Keywords: Methylation profiling by array

Project description:Spatial genome organization is essential to direct fundamental DNA-templated biological processes (e.g. transcription, replication, and repair), but the 3D in situ nanometer-scale structure of accessible cis-regulatory DNA elements within the crowded nuclear environment remains elusive. Here, we combined the recently developed Assay for Transposase-Accessible Chromatin with visualization (ATAC-see), PALM super-resolution imaging and lattice light-sheet microscope (a method termed 3D ATAC-PALM) to selectively image and quantitatively analyze key features of the 3D accessible genome in single cells. 3D ATAC-PALM reveals that accessible chromatin are non-homogeneously organized into spatially segregated clusters or accessible chromatin domains (ACDs). To directly link imaging and genomic data, we optimized multiplexed imaging of 3D ATAC-PALM with Oligopaint DNA-FISH, RNA-FISH and protein fluorescence. We found that ACDs colocalize with active chromatin and enclose transcribed genes. By applying these methods to analyze genetically purterbed cells, we demonstrated that genome architectural protein CTCF prevents excessive clustering of accessible chromatin and decompacts ACDs. These results highlight the 3D ATAC-PALM as a useful tool to probe the structure and organizing mechanism of the genome.

Project description:The aim of this work is to apply an integrated systems approach to understand the biological underpinnings of hip osteoarthritis that culminates in the need for total joint replacement (TJR). This study is a feasibility pilot that integrates functional genomics data from diseased and non-diseased tissues of OA patients who have undergone TJR. For each tissue, we characterised epigenetic marks (methylation), gene transcription (RNASeq) and expression (quantitative proteomics). We also generated genotype data on the HumanCoreExome array for each individual. This data is part of a pre-publication release.
