Rat colonic tissue transcriptome with dietary intervention by freeze-dried baby spinach (10% w/w in AIN-93 diet)

ABSTRACT: Polyposis in rat colon (Pirc) model harbors an Apc mutation and mimics human Familial Adenomatous Polyposis (FAP), allowing for intervention studies (e.g., PMID: 27706811, PMID: 30643017). RNA-sequencing of adenomatous polyps and normal colon identified genes altered by dietary spinach consumption.

Seeking insights into early onset colorectal cancer through analysis of normal colon organoids of Familial Adenomatous Polyposis patients

Project description:Here, we generated bulk RNA-seq data on colon organoids derived from both healthy and familial adenomatous polyposis patients. We related findings observed within this dataset to differential expression findings from a publicly available colorectal cancer cohort.

Single-cell transcriptomic survey of adenomatous polyposis patients with germline APC mutations

Project description:Patients with germline APC mutations are recognized by hundreds of adenoma polyps in colon, which will give rise to adenocarcinoma inevitably. Over 700 germline APC mutations have been reported to be the leading cause of adenomatous polyposis. However, the underlying mechanism of APC mutation triggered colonic cancer remains mysterious. Here, using a modified STRT-seq protocol, we analyzed over 4000 single cells from the four matching adenomatous polyposis, adenocarcinoma, adjacent normal colon tissue and one lymphatic metastasis from four adenomatous polyposis patients with APC mutations. We identified the main cell types existed in human intestine such as B cells, mast cells, T cells, macrophage cells, endothelial cells, stromal cells and epithelial cells. And the proportional changes of various cell types during the development of adenoma were showed. The transcriptomic similarities and differences between adenoma, adenocarcinoma and adjacent normal tissue were comprehensively investigated. For better understanding the tumor progression process, we also take advantage of other genomic signatures, such as SNV and CNV. We found that the gene expression signatures of adenoma and adenocarcinoma were largely similar when compared with adjacent normal tissue. But the mutation accumulation was indeed observed during the progression from adenoma to adenocarcinoma. To summarized, our work will help us accurately investigate the pathogenic mechanism and heterogeneity of APC inactive mutation triggered colonic cancer, which will also help us better understand the non-familial colorectal cancers

Heat-induced alternations in proteomic and transcriptomic profiles of spinach (Spinacia oleracea)

Project description:Spinach (Spinacia oleracea L.) is an economically important and globally consumed popular leafy vegetable that is heat-sensitive. Heat stress caused by global climate change is one of the primary deleterious elements limiting spinach production worldwide. Little work has been done to explore the heat-responsive mechanisms of spinach under high temperature-induced stress. In the present study, we used iTRAQ-based proteomic and transcriptomic approaches to investigate physiological, metabolic, and proteomic responses of spinach in response to day / night temperature of 35°C / 25°C compared to 20°C / 15°C for 4 days. A total of 3,543 differentially expressed genes (DEGs) were detected using transcriptome sequencing, of which 2,086 DEGs were downregulated and 1,457 were upregulated. The DEGs were mainly involved in superoxide dismutase activity, catalase, and peroxidase activity. A total of 3,246 differentially abundant proteins were detected using iTAQ-based quantitative proteomic approach, from which 567 differentially expressed proteins (DEPs) (277 upregulated and 290 downregulated) were identified. DEPs were mainly assigned to pathways related to metabolism, signal transduction, protein degradation, defense, and antioxidant. Four genes - superoxide dismutase (SOD, LOC110788339), catalase (CAT, LOC110790286), peroxidase (POD, LOC110775253), and heat shock protein (HSP, LOC110799288) - were validated using quantitative real-time PCR (qRT-PCR) to verify the proteomic and transcriptomic analyses, showing different transcriptional and translational expression levels. The findings of this study provide a fundamental understanding of the metabolic pathways and biological processes that control adaptation to heat stress in spinach, and provide novel insight into the development of heat-tolerant spinach.

Heat stress-responsive proteomics and phosphoproteomics in spinach

Project description:Elevated temperature limits plant growth and reproduction and poses a growing threat to agriculture. Plant heat stress response is highly conserved and fine-tuned in multiple pathways. Spinach (Spinacia oleracea L.) is a cold tolerant but heat sensitive green leafy vegetable. In this study, heat adaptation mechanisms in spinach sibling inbred heat-tolerant line Sp75 were investigated using physiology, proteomics, and phosphoproteomics approaches. The abundance patterns of 911 heat stress-responsive proteins, and phosphorylation level changes of 48 phosphopeptides representing 45 phosphoproteins indicated that heat induced calcium-mediated signaling, ROS homeostasis, endomembrane trafficking, and cross-membrane transport pathways, as well as > 15 transcription regulation factors. Although photosynthesis was inhibited, diverse primary and secondary metabolisms were employed for enhancing thermotolerance, such as glycolysis, pentose phosphate pathway, amino acid metabolism, fatty acid metabolism, nucleotide metabolism, vitamin metabolism, and isoprenoid biosynthesis. These data constitutes a heat stress-responsive metabolic atlas in spinach, which will springboard further investigation into the sophisticated molecular mechanism of plant heat adaptation and inform spinach molecular breeding initiatives.
