An international study of more than 50,000 people with irritable bowel syndrome (IBS) has revealed that IBS symptoms may be caused by the same biological processes as conditions such as anxiety.
The research team, including more than 40 institutions showed that overall, heritability of IBS (how much your genes influence the likelihood of developing a particular condition) is quite low, indicating the importance of environmental factors such as diet, stress and patterns of behaviour that may also be shared in the family environment.
However, 6 genetic differences were more common in people with IBS than in controls. Researchers found most of the altered genes appear to have more clear-cut roles in the brain and possibly the nerves which supply the gut, rather than the gut itself.
The team also looked for overlap between susceptibility to IBS and other physical and mental health conditions. They found that the same genetic make-up that puts people at increased risk of IBS also increases the risk for common mood and anxiety disorders such as anxiety, depression, and neuroticism, as well as insomnia. However, this doesn’t mean that anxiety causes IBS symptoms or vice versa.

Inflammatory bowel disease (IBD) is a chronic inflammatory disease associated with increased risk of gastrointestinal cancers. We whole-genome sequenced 446 colonic crypts (intestinal glands in the colon) from 46 IBD patients and compared these to 412 crypts from 41 non-IBD controls from our previous publication on the mutation landscape of the normal colon.View publication

Mutations in FAMIN cause arthritis and inflammatory bowel disease in early childhood, and a common genetic variant increases the risk for Crohn’s disease and leprosy. Researchers developed an unbiased liquid chromatography-mass spectrometry screen for enzymatic activity of this orphan protein.View publication

The most common causes of chronic liver disease are excess alcohol intake, viral hepatitis and non-alcoholic fatty liver disease.
The genome of HCC exhibits diverse mutational signatures, resulting in recurrent mutations across more than 30 cancer genes. Stem cells from normal livers have a low mutational burden and limited diversity of signatures, which suggests that the complexity of HCC arises during the progression to chronic liver disease and subsequent malignant transformation.

Researchers have previously described a prognostic transcriptional signature in CD8 T cells that separates patients with IBD into two phenotypically distinct subgroups, termed IBD1 and IBD2. They sought to develop a blood-based test that could identify these subgroups without cell separation, and would be suitable for clinical use in Crohn’s disease (CD) and ulcerative colitis (UC).
