Cancer Research: Hybrid cells cause chaos around cancers ♦ New technique for precise light-activated chemotherapy drugs ♦ Super graphene can help treat cancer

Hybrid cells cause chaos around cancers Like all cells, those in tumors need access to the body's fine network of blood vessels to bring them oxygen and carry away waste. Tumors have learned to game the process called angiogenesis in which new vessels sprout from existing ones, like branches from a tree. Now, researchers have built a simulation to understand how cancerous tumors manipulate blood-vessel growth
Multiple myeloma hides in bones like a wolf in sheep's clothing Multiple myeloma uses a trick akin to a wolf in sheep’s clothing to grow in and spread to new bone sites. By overexpressing Runx2, a gene that normally is a master regulator of bone formation, the cells of this largely incurable cancer produce proteins that mimic the normal bone-resident cells.
New technique for precise light-activated chemotherapy drugs A new technique that uses light to activate chemotherapy drugs in specific cells shows promise as a way to improve the effectiveness of cancer therapies while preventing severe side effects, according to a study. The approach could be used to treat a range of tumors with unprecedented precision by making existing cancer drugs sensitive to light
Super graphene can help treat cancer Silver is often used as a coating on medical equipment used for chemotherapy. The problem is that this silver coating can break down drugs. Now, researchers have found a graphene coating that will help boost chemotherapy's effects.
Cell structure discovery advances understanding of cancer development A cell structure has been discovered that could help scientists understand why some cancers develop. For the first time, a structure called 'the mesh' has been identified which helps to hold together cells. This discovery changes our understanding of the cell's internal scaffolding.
