Malignant cancer cells not only proliferate faster than most healthy cells in our bodies. They also generate more “junk”, such as faulty and damaged proteins. This makes cancer cells inherently more dependent on the most important cellular garbage disposal unit, the proteasome, which degrades defective proteins and removes them from circulation. Treatments for some types of cancer, such as multiple myeloma – a type of bone marrow cancer – exploit this dependence. Patients are treated with inhibitors, which selectively block the proteasome. The ensuing pile-up of cellular junk overwhelms the cancer cell, ultimately killing it.
