title: [Studies of YB-1 protein in breast tumors].
abstract: The multifunctional mammalian protein YB-1 is involved in multiple DNA- and mRNA-dependent events in the cell and regulates gene expression at different levels. The intracellular localization and relative mRNA content of YB-1 in the breast tumors were studied. The presence of cells with nuclear YB-1 localization in the tumor cell population is a poor predictor that correlates with larger tumors (more than 5 cm). The high YB-1 mRNA content in the breast tumors promotes metastasis of small neoplasms and patients with breast cancer who have high tumor tissue YB-1 mRNA levels may referred to as an early distant metastasis risk group. The findings suggest that combined determination of YB-1 intercellular localization and mRNA levels can ensure a more reliable prognosis of breast cancer.
