Abstract
Breast cancer ranks as the most prevalent form of cancer globally. Currently, advanced screening methods have significantly improved early detection rates. These achievements have led to more non-invasive cancer diagnoses and underscored the clinical relevance of precursor lesions like flat epithelial atypia (FEA), a histological condition characterized by mild atypical changes in the normal epithelium lining the mammary ducts. Despite the increasing detection of FEA in mammary biopsy, our understanding of the biological behavior of this entity remains limited and, as a consequence, the clinical management of patients is still being debated. Evidence from the literature indicates that dysregulation of microRNAs contributes to all stages of breast cancer progression, potentially serving as valuable markers of disease evolution. In this study, through a comparison of the microRNA profiles of normal mammary epithelium, FEA, and non-invasive breast cancer in three cohorts of patients, we identified downregulation of miR-1297 as a common feature in both FEA and non-invasive breast cancer compared to the normal counterpart. Mechanistically, overexpression of miR-1297 inhibits the growth of breast cancer cells by targeting the oncogenic receptor tyrosine kinase EphrinA2. In contrast, downregulation of miR-1297 increases proliferation and alters the morphology of normal mammary epithelial cells in a three-dimensional context. These findings pinpoint the downregulation of miR-1297 as an early event in mammary transformation and suggest its potential role as a driver of progression in FEA, harboring the capacity to evolve into malignancy.

High-Throughput Sequencing of Circulating MicroRNAs in Plasma and Serum during Pregnancy Progression. Life (Basel) 2021; 11:life11101055. [PMID: 34685426 PMCID: PMC8539647 DOI: 10.3390/life11101055] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 09/28/2021] [Accepted: 10/01/2021] [Indexed: 12/31/2022] Open
Abstract
Although circulating microRNAs (miRNAs) in maternal blood may play an important role in regulation of pregnancy progression and serve as non-invasive biomarkers for different gestation complications, little is known about their profile in blood during normally developing pregnancy. In this study we evaluated the miRNA profiles in paired plasma and serum samples from pregnant women without health or gestational abnormalities at three time points using high-throughput sequencing technology. Sequencing revealed that the percentage of miRNA reads in plasma and serum decreased by a third compared to first and second trimesters. We found two miRNAs in plasma (hsa-miR-7853-5p and hsa-miR-200c-3p) and 10 miRNAs in serum (hsa-miR-203a-5p, hsa-miR-495-3p, hsa-miR-4435, hsa-miR-340-5p, hsa-miR-4417, hsa-miR-1266-5p, hsa-miR-4494, hsa-miR-134-3p, hsa-miR-5008-5p, and hsa-miR-6756-5p), that exhibit level changes during pregnancy (p-value adjusted < 0.05). In addition, we observed differences for 36 miRNAs between plasma and serum (p-value adjusted < 0.05), which should be taken into consideration when comparing the results between studies performed using different biosample types. The results were verified by analysis of three miRNAs using qRT-PCR (p < 0.05). The present study confirms that the circulating miRNA profile in blood changes during gestation. Our results set the basis for further investigation of molecular mechanisms, involved in regulation of pregnancy, and the search for biomarkers of gestation abnormalities.
