Item The Expression of Prolactin Receptors in Benign Breast Tumors Is Not Associated with Serum Prolactin Level(MDPI, 2021) Коломієць, Олена Олегівна; Коломиец, Елена Олеговна; Kolomiiets, Olena Olehivna; Язиков, Олександр Валерійович; Языков, Александр Валерьевич; Yazykov, Oleksandr Valeriiovych; Піддубний, Артем Михайлович; Поддубный, Артем Михайлович; Piddubnyi, Artem Mykhailovych; Линдін, Микола Сергійович; Лындин, Николай Сергеевич; Lyndin, Mykola Serhiiovych; Лукавенко, Іван Михайлович; Лукавенко, Иван Михайлович; Lukavenko, Ivan Mykhailovych; Андрющенко, Володимир Вікторович; Андрющенко, Владимир Викторович; Andriushchenko, Volodymyr Viktorovych; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Москаленко, Роман Андрійович; Москаленко, Роман Андреевич; Moskalenko, Roman AndriiovychThe role of prolactin (PRL) and its receptors in the initiation and development of benign breast tumors (BBT) has not been sufficiently studied. An imbalance in the system of hormone homeostasis is crucial in the development of BBT. In particular, an association between elevated prolactin levels and the development of BBT has been reported. Our study showed no significant differences between PRL receptor (PRL-R) expression in BBT tissue under normal and elevated serum PRL levels. There was also no significant correlation between age, PRL-R expression in BBT tissue, intact tissue, and PRL level in the serum. There was a strong significant correlation (p < 0.01; r = 0.92) between PRL-R expression in BBT samples and intact breast tissue, which did not depend on the serum PRL level. There was also no significant difference in the expression of the proliferative marker Ki-67 in BBT tissues from women with normal and elevated levels of serum PRL (p > 0.05). No signs of PRL and its receptors were detected in the BBT cystic fluid women with elevated serum PRL levels. In summary, our prospective study showed that the expression of PRL-R in the tissue of BBT and physiological breast tissue does not depend on the level of serum PRL.Item Тhe role of prolactin receptor expression in the development of benign breast pathology(Sumy State University, 2020) Коломієць, Олена Олегівна; Коломиец, Елена Олеговна; Kolomiiets, Olena Olehivna; Язиков, Олександр Валерійович; Языков, Александр Валерьевич; Yazykov, Oleksandr Valeriiovych; Лукавенко, Іван Михайлович; Лукавенко, Иван Михайлович; Lukavenko, Ivan Mykhailovych; Андрющенко, Володимир Вікторович; Андрющенко, Владимир Викторович; Andriushchenko, Volodymyr Viktorovych; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Москаленко, Роман Андрійович; Москаленко, Роман Андреевич; Moskalenko, Roman AndriiovychToday, hyperprolactinemia is considered as one of the main causes of breast pathology (BP) in women of reproductive age. To investigate the relationship between the expression of prolactin receptors (PRL-R) and serum prolactin (PRL) in benign breast tumors and normal breast tissue.Item The existence of calcifications in breast cancer tissue doesn’t affect expression of HER2-neu protein(Springer, 2020) Коломієць, Олена Олегівна; Коломиец, Елена Олеговна; Kolomiiets, Olena Olehivna; Язиков, Олександр Валерійович; Языков, Александр Валерьевич; Yazykov, Oleksandr Valeriiovych; Лукавенко, Іван Михайлович; Лукавенко, Иван Михайлович; Lukavenko, Ivan Mykhailovych; Андрющенко, Володимир Вікторович; Андрющенко, Владимир Викторович; Andriushchenko, Volodymyr Viktorovych; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Москаленко, Роман Андрійович; Москаленко, Роман Андреевич; Moskalenko, Roman AndriiovychThere is evidence that calcifications in breast cancer (BC) may have an active role in mitogenesis and upregulation of gene expression. To investigate the effect of presence of microcalcifications in breast cancer tissue on Her2-neu expression.
