Background of the Study
Breast cancer is a complex disease with diverse molecular subtypes, and understanding gene expression patterns in tumor cells is critical for developing targeted therapies. At Usmanu Danfodiyo University, Sokoto State, researchers are designing a computational biology framework to analyze high-throughput RNA sequencing data and elucidate the genetic mechanisms driving breast cancer progression. The framework integrates differential expression analysis, clustering, and pathway enrichment to identify key genes and regulatory networks associated with tumor development (Ibrahim, 2023). Machine learning algorithms, including support vector machines and deep neural networks, are employed to classify tumor subtypes based on gene expression profiles and predict patient outcomes. The system is built to handle large datasets through cloud-based computing, ensuring rapid data processing and scalable analysis. Advanced data visualization tools enable researchers and clinicians to interpret complex gene expression patterns, facilitating the identification of potential biomarkers for early detection and personalized treatment (Chukwu, 2024). The interdisciplinary collaboration among computational biologists, oncologists, and data scientists ensures that the framework is both technically robust and clinically relevant. By automating the analysis process and reducing human error, this framework aims to streamline the discovery of novel therapeutic targets and improve prognostic assessments. Ultimately, the research strives to advance precision oncology by providing a comprehensive tool that enhances our understanding of breast cancer biology and informs the development of tailored treatment strategies (Adebayo, 2023).
Statement of the Problem
Despite rapid advancements in genomic technologies, accurately characterizing gene expression in breast cancer remains challenging due to tumor heterogeneity and the complex interplay of regulatory mechanisms. At Usmanu Danfodiyo University, conventional analytical methods often fail to capture dynamic gene expression profiles, leading to incomplete models and conflicting results (Bello, 2023). The absence of an integrated computational framework hampers the identification of critical genes and pathways involved in tumor progression, delaying the translation of research into clinical practice. Moreover, manual analysis of large-scale transcriptomic data is time-consuming and prone to error, affecting the reproducibility of findings. There is a pressing need for an automated, scalable system that combines robust statistical methods with advanced machine learning to improve the accuracy of gene expression analysis in breast cancer. This study proposes the development of such a framework to standardize data processing, reduce analysis time, and enhance the predictive power of gene expression models. Addressing these challenges is vital for the early detection of breast cancer and for the development of targeted, personalized therapies that can improve patient outcomes. The framework will facilitate a more detailed understanding of the molecular basis of breast cancer, thereby supporting the advancement of precision oncology and contributing to improved clinical management of the disease (Okafor, 2024).
