The Role of Different Types of microRNA in the Pathogenesis of Breast and Prostate Cancer. Int J Mol Sci 2023; 24:ijms24031980. [PMID: 36768298 PMCID: PMC9916830 DOI: 10.3390/ijms24031980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 01/16/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
Abstract
Micro ribonucleic acids (microRNAs or miRNAs) form a distinct subtype of non-coding RNA and are widely recognized as one of the most significant gene expression regulators in mammalian cells. Mechanistically, the regulation occurs through microRNA binding with its response elements in the 3'-untranslated region of target messenger RNAs (mRNAs), resulting in the post-transcriptional silencing of genes, expressing target mRNAs. Compared to small interfering RNAs, microRNAs have more complex regulatory patterns, making them suitable for fine-tuning gene expressions in different tissues. Dysregulation of microRNAs is well known as one of the causative factors in malignant cell growth. Today, there are numerous data points regarding microRNAs in different cancer transcriptomes, the specificity of microRNA expression changes in various tissues, and the predictive value of specific microRNAs as cancer biomarkers. Breast cancer (BCa) is the most common cancer in women worldwide and seriously impairs patients' physical health. Its incidence has been predicted to rise further. Mounting evidence indicates that microRNAs play key roles in tumorigenesis and development. Prostate cancer (PCa) is one of the most commonly diagnosed cancers in men. Different microRNAs play an important role in PCa. Early diagnosis of BCa and PCa using microRNAs is very useful for improving individual outcomes in the framework of predictive, preventive, and personalized (3P) medicine, thereby reducing the economic burden. This article reviews the roles of different types of microRNA in BCa and PCa progression.

Correlation of the Levels of microRNA with Cell Composition of Axillary Lymph Node in Wistar Rats with Breast Cancer. Bull Exp Biol Med 2020; 168:500-502.

Abstract
We studied the levels microRNA (miR-21, miR-221, miR-222, and miR-429) in blood serum, thoracic duct lymph, and breast cancer tissue, as well as the cell composition of the axillary lymph node in Wistar female rats with chemically induced breast cancer. The levels of miR-221 and miR-429 in the tumor tissue and in the lymph correlated with the decrease in lymphocyte number in the medullary cords of the axillary lymph nodes.
