Abstract
Background:
Breast cancer is the leading cause of cancer-related mortality
among women worldwide. Advanced stages are usually obstinate with chemotherapy, resulting
in a poor prognosis; however, they are treatable if diagnosed early.
Objective:
Identifying biomarkers that can detect cancer early or have therapeutic significance
is imperative.
Methods:
Herein, a comprehensive bioinformatics-based transcriptomics study of breast
cancer for identifying differentially expressed genes (DEGs), followed by a screening of
potential compounds by molecular docking, was performed. Genome-wide mRNA expression
data of breast cancer patients (n=248) and controls (n=65) were retrieved from
the GEO database for meta-analysis. Statistically significant DEGs were used for enrichment
analysis based on ingenuity pathway analysis and protein-protein network analysis.
Results:
A total of 3096 unique DEGs (965 up-regulated and 2131 down-regulated) were
mapped as biologically relevant. The most upregulated genes were COL10A1, COL11A1,
TOP2A, BIRC5 (survivin), MMP11, S100P, RARA, and the most downregulated genes
were ADIPOQ, LEP, CFD, PCK1 and HBA2. Transcriptomic and molecular pathway
analyses identified BIRC5/survivin as a significant DEG. Kinetochore metaphase signaling
is recognized as a prominent dysregulated canonical pathway. Protein-protein interaction
study revealed that KIF2C, KIF20A, KIF23, CDCA8, AURKA, AURKB, INCENP,
CDK1, BUB1 and CENPA are BIRC5-associated proteins. Molecular docking was performed
to exhibit binding interactions with multiple natural ligands.
Conclusion:
BIRC5 is a promising predictive marker and a potential therapeutic target in
breast cancer. Further large-scale studies are required to correlate the significance of BIRC5
in breast cancer, leading to a step toward the clinical translation of novel diagnostic
and therapeutic options.
