This thesis is devoted to the studying of the gene methylenetetrahydrofolate reductase (MTHFR) mutations in inflammation mediators activation, prooxidant and profibrotic agents in patients with breast cancer. It was found that the prevalence of С677Т MTHFR mutations in patients with BC is higher than in the general population. In patients with heterozygous CT and homozygous TT allele of MTHFR gene significantly increases homocysteine level, interleykin-6, SRP, TGF-b1, free oxyproline and markers of oxidative stress.

This increases the risk of pulmonary fibrosis, especially after chemo-radiation therapy. 
 

Key words: breast cancer, MTHFR gene mutations, homocysteine, oxidative stress, markers of inflammation, TGF-b1.
