Personalized Approach to Assessing mRNA Expression of Histidine-Rich Glycoprotein and Immunohistochemical Markers in Diseases of the Breast

Аннотация

Biopsy material of patients with malignant and benign breast diseases was examined. HRG mRNA expression was detected in 70% of cases in biopsy material obtained from patients with nonspecific invasive carcinoma and in 66.7% of cases in biopsy material of patients with benign breast diseases. Immunohistochemical analysis revealed expression of collagen II, the beta-1 integrin, and E-cadherin—markers of epithelial–mesenchymal transition. The use of RT-qPCR combined with immunohistochemical study made it possible to identify atypical cells, which can be regarded as precancerous changes, in individual patients.
