Changes in Levels of MiR-21, MiR-27a, MiR-221, and MiR-429 in the Thymus after Photodynamic Therapy and Surgical Treatment of Breast Cancer in Female Wistar Rats.
We studied the expression levels of microRNAs (miR-21, miR-27a, miR-221, and miR-429) in the thymus of female Wistar rats after surgical treatment of breast cancer (BC) and after photodynamic therapy for BC followed by tumor resection. In the group without treatment, the levels of pro-oncogenic miR-21, miR-27a, and miR-221 in the thymus were reduced in comparison with those in the group of intact control. After surgical treatment of BC, the levels of miR-21 and miR-27a in the thymus increased in comparison with those in BC without treatment. Surgical removal of the tumor followed by photodynamic therapy led to an even greater increase in the levels of miR-21 and miR-27a in the thymus in comparison with those in the group of surgical treatment alone. Expression of the tumor-suppressive miR-429 in the thymus significantly exceeds the levels in the BC without treatment and BC+surgery groups.
期刊介绍：
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
