Like the M 1 and M 3 muscarinic receptor, M 5 receptors are coupled with G proteins of class Gq that upregulate phospholipase C and, therefore, inositol trisphosphate and intracellular calcium as a signaling pathway.
Radioactive iodine is a very effective type of treatment for cancer of the thyroid gland. Thyroid cells absorb iodine. The radioactive iodine from the drink or capsule is absorbed into your body and picked up by the thyroid cancer cells wherever they are. So it can kill the cancer cells even if they have spread.
Two laboratory studies found that the flavonoids apigenin and luteolin, found in celery, artichokes and herbs like Mexican oregano, kills human pancreatic cancer cells in vitro by inhibiting an important enzyme.he researchers used the flavonoids as a pre-treatment instead of applying them and the chemotherapeutic drug simultaneously, said co-author Jodee Johnson, PhD from the University of Illinois. Apigenin alone induced cell death in two aggressive human pancreatic cancer cell lines.
