The fucosyltransferase 2 gene () mediates the synthesis of histoblood group antigens (HBGA) that occur from multiple organs, particularly on the surface of intestinal epithelial cells and body fluids. To date, many studies have demonstrated that the interaction of HBGA with the host microbiota is the cause of pathogenesis of intestinal diseases, making non-secretor a risk factor for inflammatory bowel disease (IBD) due to the lack of HBGA. As HBGA also acts as an attachment site for norovirus (NoV) and rotavirus (RV), the non-secretor becomes a protective factor for both viral infections. In addition, the interaction of norovirus and rotavirus with symbiotic bacteria has been found to play an important role in regulating enteroviral infection in IBD. Given the current incomplete understanding of the complex phenomenon and the underlying pathogenesis of intestinal diseases such as IBD, it has recently been hypothesized that the gene regulates intestinal bacteria through attachment sites, may help to unravel the role of and intestinal flora in the mechanism of intestinal diseases in the future, and provide new ideas for the prevention and treatment of intestinal diseases through more in-depth studies.

Documented worldwide, impaired immunity is a cardinal signature resulting from loss of dietary zinc, an essential micronutrient. A steady supply of zinc to meet cellular requirements is regulated by an array of zinc transporters. Deletion of the transporter Zip14 (Slc39a14) in mice produced intestinal inflammation.

Colorectal cancer is one of the most common malignant tumors in the world, and about 50% of its advanced patients will have liver metastasis. Preoperative assessment of the risk of liver metastasis in patients with colorectal cancer is of great significance for making individualized treatment plans. Traditional imaging examinations and tumor markers have some limitations in predicting the risk of liver metastasis.

Background: Colorectal cancer (CRC) is one of the most common cancers worldwide. The mechanisms underlying metastasis, which contributes to poor outcomes, remain elusive.
Methods: We used the Cancer Genome Atlas dataset to compare mRNA expression patterns of integrin α6 (ITGA6) and integrin β4 (ITGB4) in patients with CRC.
Long-term outcomes of endoscopic submucosal dissection for T1b colorectal cancer.

Department of Gastroenterology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, P. R. China.
Background: Endoscopic submucosal dissection (ESD) is a standardized procedure for intramucosal and slightly invasive submucosal colorectal cancers (CRC). However, the role of ESD for T1b (depth of submucosal invasion: ≥1,000 μm) CRC remains unclear. This study aimed to investigate the long-term efficacy and safety of ESD for T1b CRC.
