    ..The role of local estrogen production (aromatase activity) in this setting deserves special study. ..
  3. Berstein L, Poroshina T, Kovalenko I, Vasilyev D. Serum Levels of 8-Hydroxy-2'-Deoxyguanosine DNA in Patients with Breast Cancer and Endometrial Cancer with and without Diabetes Mellitus. Bull Exp Biol Med. 2016;161:547-9 pubmed publisher
    ..The causes of the trend to a less favorable course of tumor process in patients with breast cancer and diabetes in comparison with endometrial cancer and diabetes deserve further studies. ..

    ..The cellular context (including loss of sensitivity to TAM and estrogen deprivation) is of importance in influencing breast cancer responses to MF and to a combination of MF and TAM. ..

    Berstein L, Boyarkina M, Vasilyev D, Poroshina T, Kovalenko I, Imyanitov E, et al. Endocrine metabolic disorders in patients with breast cancer, carriers of BRCA1 gene mutations. Bull Exp Biol Med. 2012;152:610-2 pubmed
    ..BRCA1 gene mutations in breast cancer patients were associated with signs of estrogenization and a pro-genotoxic shift in the estrogen and glucose system, which could modulate the disease course and requires correction. ..
