Cancer cell membranes and intracellular compartments

Cancer cell membranes and intracellular compartments represent the structural and functional boundaries of malignant cells, including the plasma membrane and organelles like mitochondria, lysosomes, and the endoplasmic reticulum [1] (Nature Reviews Cancer, 2011). These structures are vital for cell survival, as they regulate signal transduction, nutrient transport, and metabolic processes [1, 2] (CA: A Cancer Journal for Clinicians, 2011). In cancer, these compartments often exhibit distinct biophysical properties, such as altered lipid composition (e.g., increased phosphatidylserine on the outer leaflet) and modified pH gradients, which can be exploited for therapeutic intervention [3, 4] (Advanced Drug Delivery Reviews, 2013; Journal of Controlled Release, 2014). Therapeutic strategies targeting these areas typically employ non-traditional mechanisms, such as photodynamic therapy to generate cytotoxic reactive oxygen species or the use of nanoparticle-based delivery systems for localized drug release [2, 3]. While critical for cell survival, targeting these broad cellular structures poses significant challenges regarding selectivity and the risk of damaging healthy tissues [4].
