Antioxidants are thought of to be the one-stop resolution to most well being points. They’ll struggle free radicals and forestall oxidative stress which delays ageing, reduces the chance of persistent illnesses and even helps the physique struggle most cancers.

Nonetheless, new analysis carried out on the Lautenberg Middle for Immunology and Most cancers Analysis, Hebrew College of Jerusalem (HUJI) suggests that every one just isn’t so good on the planet of antioxidants.

Specifically, gallic acid, an antioxidant current in meals like tea and wine and produced by the intestine microbiota, can push doubtlessly cancerous proteins to trigger tumours within the colon.

P53 and most cancers

Each cell in our physique has a gene known as TP53 which produces a protein known as p53. This protein regulates the cell cycle (the multiplication of physique cells) and retains them from turning into tumours. It’s known as the guardian of the genome because it prevents the replication of probably dangerous cells. So, any mutation in p53 can result in most cancers.

Instances of colon most cancers

The research was reportedly accomplished to seek out why about 98% of all cancers within the intestines begin within the colon and solely 2% within the small gut.

To seek out a solution to the query, a analysis staff led by Dr Eliran Kadosh, a researcher at HUJI, launched a mutated model of p53 into mice that had intestinal most cancers as a result of deletion of p53 gene.

Apparently, it was discovered that p53 mutations don’t act the identical in all components of the intestines and the intestine microbiome might have a job to play on this.

Within the colon, a mutated p53 had the anticipated cancer-promoting impact, nevertheless, within the small gut, it didn’t trigger most cancers regardless of the mutation. The mutated p53 nonetheless had a tumour-suppressor impact within the small gut they usually diminished the irregular cells on this space of the gut.

Intestine microbiome and gallic acid

It was the intestine microbiome that was answerable for abolishing the tumour suppressive results of p53 within the colon.

Nonetheless, the research indicated that it wasn’t the entire microbiome however solely considered one of their metabolites – gallic acid – that was answerable for the cancer-supporting impact of mutated p53.

Even when the mutated p53 was launched into mice that had no intestine microbiota and had been supplemented with an antioxidant-rich weight loss plan, the protein supported tumour development.

“The intestine micro organism had a Jekyll and Hyde impact on the mutated p53 proteins. Within the small bowel they switched course and attacked the cancerous cells, whereas within the colon they promoted the cancerous development,” stated, Dr Yinon Ben-Neriah, a professor at HUJI and the corresponding writer of the research, in a information launch.

The authors of the research additionally instructed that this discovering could also be fairly essential for individuals who have a household historical past of colorectal most cancers. The p53 mutation is among the commonest driving elements for colorectal most cancers and is taken into account to be a attainable danger issue for the genetic susceptibility of an individual to colon most cancers.
