Project description:Raw sequencing data for the proof-of-principal 1D and 2D gridmode transcriptomics performed after C3PO in the following article: https://www.biorxiv.org/content/10.1101/2024.03.12.584578v1.full. The 1D data is found in the limb68 samples here (limb #3 in the article) and the 2 replicates of the 2D data is found in the L127 samples (limb #4 in the article) and L128 samples (limb #5 in the article). For the 2D data the P# value in the filename indicates the corresponding FACS gate.
Project description:bri1-5 is a weak mutant of Brassinosteroid Insensitive 1 (BRI1). Suppressors by activation tagging bri1-1D, brs1-1D and bak1-1D can recover bri1-5 phenotype. We use microarray to investigate which pathways or functional categories have been transcriptionally regulated by bri1-1D, brs1-1D and bak1-1D.

Project description:These data were used in the spatial transcriptomics analysis of the article titled \\"Single-Cell and Spatial Transcriptomics Analysis of Human Adrenal Aging\\".
Project description:To investigate spatial heterogeneities in the axolotl forebrain, a coronal section of it was obtained for spatial transcriptomics using Visium V1.
Project description:Spatial organization of different cell types within prenatal skin across various anatomical sites is not well understood. To address this, here we have generated spatial transcriptomics data from prenatal facial and abdominal skin obtained from a donor at 10 post conception weeks. This in combination with our prenatal skin scRNA-seq dataset has helped us map the location of various identified cell types.
Project description:To reveal the spatial distribution and the difference gene expression pattern of cancer cells in colorectal cancer, Visium spatial transcriptomics of four CRC patients was applied
Project description:We developed an analysis pipeline that can extract microbial sequences from Spatial Transcriptomic (ST) data and assign taxonomic labels, generating a spatial microbial abundance matrix in addition to the default host expression matrix, enabling simultaneous analysis of host expression and microbial distribution. We called the pipeline Spatial Meta-transcriptome (SMT) and applied it on both human and murine intestinal sections and validated the spatial microbial abundance information with alternative assays. Biological insights were gained from this novel data that that demonstrated host-microbe interaction at various spatial scales. Finally, we tested experimental modification that can increase microbial capture while preserving host spatial expression quality and, by use of positive controls, quantitatively demonstrated the capture efficiency and recall of our methods. This proof of concept work demonstrates the feasibility of Spatial Meta-transcriptomic analysis, and paves the way for further experimental optimization and application.
Project description:Metaproteomics is a powerful tool to characterize the structure of microbial communities and the physiology, metabolism and interactions of the species in these communities. Metaproteomics seeks to identify and quantify proteins from microbial communities on a large scale using gel electrophoresis or advanced liquid chromatography (LC) combined with high-resolution, accurate-mass mass spectrometry. To achieve extensive coverage of a metaproteome using shotgun proteomics, the sample complexity has to be decreased, for which a main approach is the on-line separation of peptides using one or more LC dimensions. The aim of this study is to test different 1D- and 2D-LC methods, also in comparison with the standard GeLC (pre-separation of proteins via gel electrophoresis) to find the best approach for analyzing metaproteome samples, using a mock community with 32 species in different abundances.
