The combination, based on the scientists help delayed tumour development in mice
Previous studies have hinted on the link between diet and malignancy treatment, according to the latest one released in the journal Nature Communications, a fasting-mimicking diet could be more effective at dealing with some types of cancer when coupled with vitamin C. The study was executed by the scientists from USC as well as the IFOM Cancer Institute in Milan.
The combination, according to the scientists assist delayed tumour progression in several mouse models of colorectal cancer; while in some mice, it caused illness regression.
“For the first time, we have shown how a completely non-toxic intervention may effectively treat an aggressive malignancy,” said Valter Longo, the research senior author and the director from the USC Longevity Institute at the USC Leonard Davis School associated with Gerontology and professor of biological sciences at the USC Dornsife College of Letters, Arts and Sciences.
“We have taken two treatments that are researched extensively as interventions to hold off ageing– a fasting-mimicking diet plus vitamin C — and mixed them as a powerful treatment to get cancer,” added Longo.
While it is a challenge for many cancer sufferers to fast, a much safer choice would be a low-calorie, plant-based diet that triggers cells to respond as if the body had been fasting, according to the researchers.
A low-toxicity treatment of fasting-mimicking diet plus supplement C may have the potential to replace a lot more toxic treatments, the findings recommended.
Recent studies have pointed at the effectiveness of vitamin C in fighting cancer, especially if it is combined with the potent treatment.
Through this brand new study, the research team tried to check out whether a fasting-mimicking diet can enhance the high-dose vitamin C tumour-fighting action by creating an environment that might be unsustainable for cancer cells but nevertheless safe for normal cells.
“Our first in vitro experiment demonstrated remarkable effects. When used solely, fasting-mimicking diet or vitamin Chemical alone reduced cancer cell development and caused a minor increase in malignancy cell death. But when used collectively, they had a dramatic effect, eliminating almost all cancerous cells,” mentioned Longo.
The study also supplied clues about why previous research of vitamin C as a possible anticancer therapy showed limited effectiveness. By itself, a vitamin C therapy appears to trigger the KRAS-mutated tissues to protect cancer cells by boosting levels of ferritin, a protein that will binds iron.
During their analysis, scientists reduced levels of ferritin, which usually helped them increase vitamin C’s toxicity for the cancer cells. And because of this finding, they were also able realize that colorectal cancer patients with higher levels of the iron-binding protein have a reduced chance of survival.
“In this research, we observed how fasting-mimicking diet plan cycles are able to increase the effect of medicinal doses of vitamin C towards KRAS-mutated cancers,” said Maira Di Tano, a study co-author on the IFOM, FIRC Institute of Molecular Oncology in Milan, Italy.
“This occurs through the regulation of the degrees of iron and of the molecular systems involved in oxidative stress. The results especially pointed to a gene that manages iron levels: heme-oxygenase-1,” additional Tano.
The research team’s earlier studies have shown slow progression price due to fast mimicking diet, producing chemotherapy more effective in tumour tissues while protecting normal cells through chemotherapy-associated side effects.
However, they emphasized the fact that the combination of the diet along with vitamin C enhances the immune system system’s anti-tumour response in cancer of the breast and melanoma mouse models.
The team’s goal was to study when the non-toxic combination interventions would work within mice, and that it would look encouraging for human clinical trials.The particular team is now investigating the particular effects of the fasting-mimicking diets in combination with different cancer-fighting drugs.
