Correlation between Structural Transformations in Mesenteric Lymph Nodes and the Levels MicroRNA during Polychemotherapy of Breast Cancer

摘要

We studied interrelationships between the cytoarchitectonics of the mesenteric lymph node and the levels of microRNA-21, microRNA-221/222, and microRNA-429 in the lymph, blood serum, and breast tissues in female Wistar rats with chemically induced breast cancer. After polychemotherapy, significant correlations were found between miRNA-221 and the number of lymphoblasts in the germinal centers and between miRNA-222 and the number of lymphoblasts in the germinal centers and macrophages in the medullary cords of the mesenteric lymph nodes.
