The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.

Pancreatic cancer is cancer that forms in the cells of the pancreas. Pancreatic cancer begins in the tissues of your pancreas an organ in your abdomen that lies behind the lower part of your stomach. Your pancreas releases enzymes that aid digestion and produces hormones that help manage your blood sugar.

There are three types of ovarian cancers: epithelial ovarian carcinomas, germ cell tumors, and stromal cell tumors. Each has different characteristics and traits: About 85% to 90% of these cancers start in the cells that cover the outer surface of the ovary.

Extracellular vesicles (EVs) are small, membrane-bound particles released by cells into the extracellular environment. They contain various biomolecules, including proteins, nucleic acids, and lipids, and play crucial roles in intercellular communication. EVs are involved in diverse physiological processes, such as immune response regulation, tissue repair, and cell signaling. They are also emerging as potential biomarkers for various diseases, including cancer, neurodegenerative disorders, and cardiovascular diseases.
