Study reveals genetic signature of colibactin implicated in the development colorectal cancers


Study reveals genetic signature of colibactin implicated in the development colorectal cancers
Escherichia coli bacteria are constitutive members of the human gut microbiota. However, some strains produce a genotoxin called colibactin, which is implicated in the development of colorectal cancer.
While it has been shown that colibactin leaves very specific changes in the DNA of host cells that can be detected in colorectal cancer cells, such cancers take many years to develop, leaving the actual process by which a normal cell becomes cancerous obscure.
The group of Thomas F. Meyer at the Max Planck Institute for Infection Biology in Berlin together with their collaborators have now been able to catch colibactin in the act of inducing genetic changes that are characteristic of colorectal cancer cells and cause a transformed phenotype - after only a few hours of infection. ....

Strong immune response may increase susceptibility to Covid-19 in some cases


Strong immune response may increase susceptibility to Covid-19 in some cases
February 17, 2021
Researchers in Berlin have observed how SARS-CoV-2 uses an immune system defense mechanism to multiply.
The study, published in the journal EMBO Molecular Medicine, carried out by the researchers revealed that SARS-CoV-2 increasingly hijack the body’s mucous membrane cells and multiply there.
“This may give us part of the explanation as to why the immune system has difficulty regulating or even defeating the infection in some people,” says Dr. Julian Heuberger, scientist at the Division of Hepatology and Gastroenterology in Charité - Universitätsmedizin Berlin’s Medical Department. ....
