Tumor cell plasma membranes and mitochondrial membranes

The tumor cell plasma membrane is the outer lipid bilayer of a cancer cell, containing unique protein and lipid compositions that regulate the entry and exit of molecules, influence drug resistance, and are involved in cell signaling, interaction with the tumor microenvironment, and metastasis[2][3]. The mitochondrial membrane is essential for maintaining mitochondrial function and is involved in the regulation of apoptosis; its permeabilization is a critical event in programmed cell death and is a focus in some anti-cancer strategies[3]. Both membranes differ from those in normal cells in lipid composition, degree of saturation, cholesterol content, and signaling platform organization, making them attractive but non-specific targets for novel cancer therapies[2][3][4].
