The benefits of ascorbate to protect healthy cells in the prevention and treatment of oncological diseases.

Health status is determined by the balance of oxidants and antioxidants which protects healthy cells against the threat of internal and external risk factors. Antioxidants such as ascorbate (vitamin C, ascorbic acid) are of fundamental importance in this respect. Ascorbate neutralizes potential damage caused by cellular oxidative stress which may be the greatest risk of damage to healthy tissue.

The PI3K-AKt-mTOR Pathway and New Tools to Prevent Acquired Hormone Resistance in Breast Cancer.

Acquired hormone resistance is an old hurdle and still represents to be a constant challenge in oncology for the medical community. Most recently, mainly following the results of BOLERO-2 study, the activation of the PI3K-AKT-mTOR pathway is considered clinically relevant for tumor escape from hormone dependence in breast cancer. In the BOLERO-2 trial, a combination of everolimus, mTOR inhibitor, and exemestane significantly prolonged the median progression free survival (PFS) compared to exemestane alone in advanced breast cancer patients with acquired endocrine resistance.
