MetabolomicsMicrobiome-produced nicotinic acid controls colon regional identity and injury susceptibility

Regional structure of the intestinal epithelium is critical for its function and is associated with the risk of specific gut diseases. However, how regionalization is established and how it influences disease susceptibility remains poorly understood. Here, we investigated the role of the gut micr...

MetabolomicsDetermination and comparison of SCFAs in serum and colon content samples: Alzheimer's disease rat as a case study (SCFA serum and colon content determination)

SCFAs are the main microbial fermentation products from dietary fibers in colon and play a key role in keeping healthy in the whole-body. However, differences of SCFAs concentration in the serum and colon samples collected from rats had attracted few attentions. Here, we optimized the extract and...

MetabolomicsPlasma Lipid Profile Reveals Plasmalogens as Potential Biomarkers for Colon Cancer Screening

In this era of precision medicine, there is an increasingly urgent need for highly sensitive tests for detecting tumors such as colon cancer (CC), a silent disease where the first symptoms may take 10-15 yr to appear. Mass spectrometry-based lipidomics is an emerging tool for such clinical diagno...

MetabolomicsLipidomics of colon tissues

Pre-IBD is a transitional state between irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), in which chronic high-fat diet intake and antibiotic exposure significantly increase intestinal inflammatory susceptibility. However, the underlying mechanisms and effective therapeutic st...

MetabolomicsDetermination and comparison of SCFAs in serum and colon content samples: Alzheimer's disease rat as a case study (Method validation)

SCFAs are the main microbial fermentation products from dietary fibers in colon and play a key role in keeping healthy in the whole-body. However, differences of SCFAs concentration in the serum and colon samples collected from rats had attracted few attentions. Here, we optimized the extract and...

MetabolomicsExtracts from sweet sorghum (Sorghum bicolor), a feedstock for biorefining, suppressed proliferation and elevated apoptosis in human colon cancer stem cells via suppression of Wnt/beta-catenin signaling pathway
In colorectal cancer, p53 is commonly inactivated, associated with chemo-resistance, and marks the transition from non-invasive to invasive disease. Cancers, including colorectal cancer, are thought to be diseases of aberrant stem cell populations, as stem cells are able to self-renew, making them l...

MetabolomicsDistinct microbes, metabolites, and the host genome define the multi-omics profiles in right-sided and left-sided colon cancer

BACKGROUND: Studies have reported clinical heterogeneity between right-sided colon cancer (RCC) and left-sided colon cancer (LCC). However, none of these studies used multi-omics analysis combining genetic regulation, microbiota and metabolites to explain the site-specific differ...

MetabolomicsAge-, sex- and proximal-distal-resolved multi-omics identifies regulators of intestinal aging in non-human primates.

The incidence of intestinal diseases increases with age, but the regulators of gut aging and the molecules linking gut aging and diseases remain largely unknown. By profiling the transcriptome, proteome, phosphoproteome and metabolome of 104 Macaca fascicularis large intestinal tissues, ...

TranscriptomicsTranscription profiling of methotrexate-treated human colon cancer C85 cells
The experiment was aimed at identification of genes whose expression is upregulated in human colon cancer C85 cells during the process of establishment of methotrexate-induced senescence.

TranscriptomicsColon tumor samples
In response to polarization cues, cultured Caco-2 cells, a human colon adenocarcinoma-derived cell line, form a polarized epithelium resembling normal enterocytes. We investigated potential signaling mechanisms activated by Caco-2 cells that might trigger the genome-wide transcriptional reprogrammi...
