London, 23/11/2018 (The People Online) – Some natural supplements, such as mannose sugars, can be & # 39; a great help for cancer treatment. According to the results of & # 39; study, funded by Cancer Research UK and Worldwide Cancer Research, and published today "Nature", this nutritional supplement seems not only to delay tumor growth, but also to improve Effect of chemotherapy in & # 39; & # 39 mice b very types. cancer, ABC points.
It is known that tumors use more glucose than normal tissue and b & # 39; health. However, it is very difficult to control the amount of & # 39; glucose in your body just by diet. F & # 39; this study, researchers found that mannose can & # 39; interferes with glucose to reduce the amount of & # 39; of sugar cancer cells can use.
Professor Kevin Ryan, a key author of the Research Institute of the Beatson Cancer Research UK, says: "Tumors require a lot of glucose to grow, so that limit how they can use to reduce cancer progression. The Problem is that normal tissues also need glucose, so we can not removing it completely from the body. in our study, we found a dose & # 39; mannose that you & # 39; up enough glucose to delayed growth of -tumur in mice, but not so much that normal tissues have been affected. this is an initial investigation, but it is hoped that the finding & # 39; that perfect balance means that, in future, mannose can & # 39 ; given to cancer patients to enhance chemotherapy without damaging their overall health. "
Tumors require a lot of glucose to grow, to b & # 39; so limit how they can use to reduce the progression of cancer.
In their study, the first researchers examined how responded mice with & # 39; pancreatic cancer, lung or skin when mannose was added to the drinking water and administered as an oral treatment. And pointed out that the increase of the supplement decreased by & # 39; significantly tumor growth and caused no side effect.
To test how mannose can & # 39; t affect cancer treatment, the mice were treated with & # 39; cisplatin and doxorubicin, two of the most drugs used in chemotherapy. They saw that mannose improved effects of chemotherapy, reduced the tumor growth, reduced the size of tumors and even increased life & # 39; a mouse.
Similarly, other types of & # 39; cancer were investigated, such as leukemia, osteosarcoma, ovarian cancer and intestines. The researchers kkulturaw cancer cells in the laboratory and then ittrattawhom mannose to see if their growth was affected.
Some cells responded well to treatment, while others were not. It was also found that the presence of & # 39; enzyme, which violates the mannose cells, was a good indicator of & # 39; how effective treatment.
Mannose sometimes used for short periods to treat urinary tract infections, but its long-term effects have not been investigated. It is important to research further before mannose can & # 39; & # 39 used in; cancer patients.
F & # 39; this sense, Martin Ledwick of & # 39; Cancer Research UK, believes that, although these results are very promising for the future & # 39; some cancer treatments, "this is a very early investigation and has not yet been tested in humans. Patients m & # 39; to prescribe themselves on mannose, because there is a real risk & # 39; adverse side effects not yet tested. it is important to consult with & # 39; doctor before drastically changing your diet or taking new supplements ».
