Personalized Approach to Determination of Histidine-Rich Glycoprotein and E-Cadherin in Supernatants of Immunocompetent Blood Cells and Breast Biopsy Specimens in Breast Malignant and Non-Malignant Disease.

The material of patients with invasive carcinoma of no special type (ICNT) and nonmalignant diseases (ND) of the mammary gland was studied. When comparing the concentrations of histidine-rich glycoprotein (HRG) and E-cadherin (CDH1), statistically significant differences between ICNT and ND by HRG in the supernatant of blood cells and its spontaneous production by biopsies and by CDH1 at its induced production, as well as by influence indices of polyclonal activators on the production of CDH1 were found. When comparing the expression of immunohistochemical markers, no statistically significant differences between ICNT and ND were obtained.

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

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.
