Studies involving commonly consumed fruit juices showed that natural fructose carbohydrates can alter lipid and protein oxidation biomarkers in the blood, and
mediate oxidative stress responses in vivo [44].
Mao's study examined mitochondria - associated gene expression in the mouse eye tissue and found significant changes in several genes involved
in oxidative stress response.
In the case of cancer, the radicals might also trigger
an oxidative stress response.
In conclusion,
oxidative stress response can have a dual function in tumours: while it increases tumour growth, it also enhances sensitivity to chemotherapy.
In last years, the «Stress and Cancer» laboratory has identified two new molecular players of
the oxidative stress response, the miR - 200 family of microRNA and the transcription factor JunD.
The expression of micro-RNA miR - 663 was induced by mitochondrial reactive oxygen species production, an apoptotic signal and
oxidative stress response, and miR - 663 induced the expression of nuclear - encoded mitochondrial respiratory chain subunits.
Oxidative stress responses in the human fungal pathogen, candida albicans.
This oxidative stress response system is also needed to repair damage incurred during heavy training.
