Unexpectedly, while breast cancer cells are resistant compared to nontransformed cells against oxidative stress inducing drugs, at the same time they are hypersensitive to lipid peroxidation and ferroptosis induced by Erastin or Rsl-3, indicating that they are ‘addicted’ to the xCT/GPX4 axis.


White blood cells work to block cell-damaging free radicals. Good sources of beta carotene are dark green leafy and yellow-orange fruits and vegetables. In the body, beta carotene is converted to vitamin A. Eating foods rich in beta carotene is recommended to possibly decrease the risk of developing stomach, lung, prostate, breast, and head and neck cancer.


Kroppens ämnesomsättning leder till stress på cellnivå, så kallad oxidativ stress, med bildning av fria radikaler som följd. Dessa ämnen är kända för att skada cellens DNA. Antioxidanter hjälper cellerna att skydda sig mot fria radikaler. Kroppen kan själv producera antioxidanter eller så kan den tillgodose sig antioxidanter från kosten.

The effects of extracts from five cultivars of strawberries on the proliferation of colon cancer cells HT29 and breast cancer cells MCF-7 were investigated, and possible correlations with the levels of several antioxidants were analyzed. In addition, the effects of organic cultivation compared to co … Vitamins E and C, selenium, carotenoids, lycopene, soy products, and green tea extract are a few substances with antioxidant properties that have been studied in detail. This article reviews the results generated over the last 20 years through in vitro and in vivo studies in various types of cancers and stages of cancer treatment. The work, conducted in mice, shows that antioxidants can change cells in ways that fuel the spread of malignant melanoma—the most serious skin cancer—to different parts of the body. The progression 2018-07-14 · Some common antioxidants: Vitamin E, selenium, zinc, N-acetylcysteine, glutathione, Vitamin C (low dose only—high doses administered by IV are oxidative), and beta-carotene. References.

In both mouse models and human cells, the antioxidants seemed to protect cancer cells by reducing the amount of DNA damage. That, in turn, reduced expression of a protein called p53.

Antioxidants and Cancer Prevention Antioxidants protect cells from damage caused by unstable molecules known as free radicals (see Question 1&3). Laboratory and animal research has shown antioxidants help prevent the free radical damage that is associated with cancer.

But there have been some recent reports that cast doubt on apoptosis being the only route for detached cell death. This latest study confirms that, but goes on to a surprise. 2016-02-14 Increasing evidence indicates that most of the tumors are sustained by a distinct population of cancer stem cells (CSCs), which are responsible for growth, metastasis, invasion, and recurrence.

Antioxidants “Administration of antioxidants to the mice allowed more of the metastasizing melanoma cells to survive, increasing metastatic disease burden.” he added.
