Precision Oncology: Emerging Molecular Methods for Drug Target Discovery

Molecular-targeted cancer therapies aim to block specific molecules essential for tumour growth and survival, resulting in enhanced efficacy and reduced side effects. This review explores various strategies, including angiogenesis inhibition, where tumour expansion is curtailed by disrupting new blood vessel formation. Targeting microtubules affects mitotic spindle formation, which is essential for cell division, thereby hindering the rapid division of cancer cells. The modulation of signal transduction pathways, particularly involving tyrosine kinases and Ras proteins, is pivotal for altering proliferative and survival signals. Metabolic transformations, nucleotide biosynthesis, and cell cycle regulation are also critical targets, given their roles in tumour growth and replication. Additionally, targeting transcription factors like NF-κB and AP-1, alongside growth factors and tumour suppressor genes, such as p53, represents another layer of therapeutic intervention. The review emphasises the significance of apoptosis induction and the inhibition of chemokines, metastasis, and various enzymes like COX-2 and LOX in the comprehensive management of cancer. This perspective focuses on the conceptual framework that has guided the search for innovative anticancer medicines.
