Project description:A functional understanding of the human body requires structure-function studies of proteins at scale. The chemical structure of proteins is controlled at the transcriptional, translational, and post-translational levels, creating a variety of products with modulated functions within the cell. The term "proteoform" encapsulates this complexity at the level of chemical composition. Comprehensive mapping of the proteoform landscape in human tissues necessitates analytical techniques with increased sensitivity and depth of coverage. Here, we took a top-down proteomics approach, combining data generated using capillary zone electrophoresis (CZE) and nanoflow reversed-phase liquid chromatography (RPLC) hyphenated to mass spectrometry to identify and characterize proteoforms from the human lungs, heart, spleen, small intestine, and kidneys. CZE and RPLC provided complementary post-translational modification and proteoform selectivity, thereby enhancing the overall proteome coverage when used in combination. Of the 11,466 proteoforms identified in this study, 7373 (64%) were not reported previously. Large differences in the protein and proteoform level were readily quantified, with initial inferences about proteoform biology operative in the analyzed organs. Differential proteoform regulation of defensins, glutathione transferases, and sarcomeric proteins across tissues generate hypotheses about how they function and are regulated in human health and disease.
Project description:To study the function of Cdk10 in the developing mouse embryo, we isolated eight tissues [heart, brain, liver, stomach, thymus, lung, spleen, kidney, intestine] on the day the pups were born [P0]. Each tissue was immediately processed for mRNA isolation.
Project description:Gene differential expression studies can serve to explore and understand the laws and 16 characteristics of animal life activities, and the difference in gene expression between different 17 animal tissues have been well demonstrated and studied. However, for the world-famous rare 18 and protected species giant panda (Ailuropoda melanoleuca), only the transcriptome of the blood 19 and spleen has been reported separately. Here, in order to explore the transcriptome differences 20 between the different tissues of the giant panda, transcriptome profiles of the heart, liver, spleen, 21 lung, and kidney from five captive giant pandas were constructed with Illumina HiSeq 2500 22 platform. The comparative analysis of the inter-tissue gene expression patterns was carried out 23 based on the generated RNA sequencing datasets. Analyses of Gene Ontology (GO) enrichment, 24 Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment, and protein-protein interaction 25 (PPI) network were performed according to the identified differentially expressed genes (DEGs). 26 We generated 194.52 GB clean base data from twenty-five sequencing libraries and identified 27 18,701 genes, including 3492 novel genes. With corrected p-value < 0.05 and |log2FoldChange| > 28 2, we finally obtained 921, 553, 574, 457, and 638 tissue-specific DEGs in the heart, liver, spleen, 29 lung, and kidney, respectively. In addition, we identified TTN, CAV3, LDB3, TRDN, and 30 ACTN2 in the heart; FGA, AHSG, and SERPINC1 in the liver; CD19, CD79B, and IL21R in the 31 spleen; NKX2-4 and SFTPB in the lung; GC and HRG in the kidney as hub genes in the PPI 32 network. The results of the analyses showed a similar gene expression pattern between the spleen 33 and lung. This study provided for the first time the heart, liver, lung, and kidney’s transcriptome 34 resources of the giant panda, and it provided a valuable resource for further genetic research or 35 other potential research.

Project description:We compiled a comprehensive list of human m6A sites in cerebellum, frontal cortex, heart, kidney, liver, lung, muscle,spleen and testis.
Project description:We performed microarray experiments to examine gene expression in human tissues. This data was used for comparison with our humanized mouse study (GEO ID GSE33846) and threshold determination of our tiling array data (GEO ID GSE18490, public in the near future). A total of 22 tissues (bone marrow, cerebellum, colon, cortex, fetal brain, heart, kidney, liver, lung, pancreas, prostate, salivary gland, skeletal muscle, small intestine, spinal cord, spleen, stomach, testes, thymus, thyroid, trachea and uterus) and 2 cell lines (HeLa and SH-SY5Y) were examined.
