Cellular proteins, membranes, and DNA repair machinery

The term Cellular proteins, membranes, and DNA repair machinery describes a heterogeneous group of biological components rather than a single molecular target. Cellular proteins encompass the vast array of enzymes and structural molecules essential for life, while membranes consist of lipid bilayers that regulate cellular transport and signaling (Escribá et al., 2008). DNA repair machinery refers to the complex network of proteins, such as those in the base excision repair or homologous recombination pathways, that maintain genomic stability (Lord & Ashworth, 2012). In oncology, these systems are often targeted collectively by non-specific agents like ionizing radiation or alkylating chemotherapeutics to induce catastrophic cellular damage and apoptosis. However, because these components are ubiquitous across all cell types, targeting them lacks the precision of modern molecularly targeted therapies, often leading to significant systemic toxicity (StatPearls, 2023).

Non-specific induction of cellular damage through alkylation, oxidation, or cross-linking of proteins, lipids, and DNA, leading to the activation of cell death pathways (PubChem, 2024).
