To investigate the clinical diagnostic potential of dysregulated microRNAs as early biomarkers in breast cancer patients

The dysregulation of epidermal growth factor receptors and hormonal receptors in breast cancer can be attributed to various factors, including the influence

of non-coding RNAs, particularly microRNAs.

These small RNA molecules play a pivotal role in post-

transcriptional gene regulation and have been implicated

as key players in breast cancer pathogenesis. In breast cancer, aberrant expression of miRNAs has been

observed, with many miRNAs found to be upregulated. These dysregulated miRNAs exert their influence by

modulating DNA repair activity and tumor suppressor

functions, thereby promoting cancer initiation and

progression and contributes to the molecular complexity

of breast cancer.

This study aims to delve into the intricate role of miRNAs

in the progression of breast cancer, elucidating their

influence on molecular markers, tumor suppressor genes, and DNA repair activity within breast cancer patient

samples. By analyzing a panel of miRNAs in these

patients, we seek to uncover potential biomarkers crucial

for diagnosing breast cancer early and distinguishing

between different subsets of the disease within a single

comprehensive study.
