New analysis establishes global microbial signatures for colorectal cancer

Cancers have long been known to arise due to environmental exposures such as unhealthy diet or smoking. Lately, the microbes living in and on our body have entered the stage as key players: while stomach cancer can be caused by a single bacterial species, Helicobacter pylori, the role that gut microbes play in the development of colorectal cancer - the third most common cancer worldwide - is less clear.

Cancer prevention drug also reduces virulence of H. pylori bacterium

A medicine currently being tested as a chemoprevention agent for multiple types of cancer has more than one trick in its bag when it comes to preventing stomach cancer, Vanderbilt researchers have discovered.

Microbiologists identify enzyme that makes Helicobacter so adaptable

The bacterial pathogen Helicobacter pylori owes its worldwide distribution to its genetic adaptability. Ludwig-Maximilians-Universitaet Munich microbiologists have identified an enzyme that plays a vital role in the flexible control of global gene expression in the species.

Harmful H. pylori may play a role in Parkinson's disease

While human genetic mutations are involved in a small number of Parkinson's disease (PD) cases, the vast majority of cases are of unknown environmental causes, prompting enormous interest in identifying environmental risk factors involved.

Scientist intends to fight pathogenic bacteria with viruses

Dr. Li Deng of Helmholtz Zentrum München has been awarded a Starting Grant of the European Research Council. The scientist intends to tackle antimicrobial resistance by fighting bacteria with their natural enemies - the viruses. The grant is endowed with nearly 1.5 million euros for five years.

Scientists find new molecular biomarker for gastric cancer

Although immunotherapy is seen as a very promising treatment for cancer, currently only 20 to 30 percent of patients respond positively. Being able to identify the people most likely to benefit from the costly therapy is a Holy Grail for oncologists.

New study finds key factors behind differences in immune responses

Age, sex, and specific human genetic variants are the key factors behind differences between immune responses among healthy humans, finds a study of 1,000 individuals carried out by EPFL and the Pasteur Institute.

Acoustic technology could offer new way to diagnose IBS

Utilizing newly adapted artificial intelligence, researchers have developed an acoustic belt that offers a new way to diagnose irritable bowel syndrome by listening to the noises in a patient's gut, according to research presented at Digestive Disease Week 2018.

Study: Disease-causing stomach bacterium shuts down energy production in host cells

Researchers report in a new study that the bacterium Helicobacter pylori - a major contributor to gastritis, ulcers and stomach cancer - resists the body's immune defenses by shutting down energy production within the cells of the stomach lining that serve as a barrier to infection.

Gastric environment permanently changes in the presence of Helicobacter pylori infection

The make-up of the human gut flora is highly individual and extremely diverse. However, when a Helicobacter pylori infection is present, this bacterium displaces all other bacteria in the gastrointestinal tract, leaving only Helicobacter bacteria in the stomach.
