Comparative Analysis of microRNA Expression in Serum and Plasma in Patients Screened for BRCA1 or BRCA2 Mutations - dataset 1

This dataset was created in order to evaluate the concordance of miRNA expression between serum and plasma in humans. miRNA expression was quantified in both biological materials using sequencing. Differential expression and correlations analysis were used to evaluate similarities and differences between miRNAs abundance in plasma and serum. Concurrently, miRNA quantification in the subset of these samples was performed by qPCR, the results of which belong to the separate submission to GEO. Generation of this dataset was supported by The Gray Foundation grant “Circulating microRNAs for assessment of risk beyond the BRCA genes and early detection of breast cancer in high-risk families” awarded to Dipanjan Chowdhury and Polish National Research Center grant OPUS “Predictive Potential of Circulating MicroRNA Biomarkers in Patients with High Familial or Genetic Risk of Cancer” (2023/49/B/NZ5/03835) awarded to Wojciech Fendler. Overall design: The experiment was performed in 30 pairs of human serum and plasma samples collected at the same time. Each sample title indicates the patient, so pairs of samples are identified. All samples came from healthy women, but some of them harbored germinal BRCA1/2 mutations as this experiment is a part of a larger study about changes in miRnome induced by BRCA mutations or the presence of BRCA-related cancers (especially ovarian and breast cancer).
