New technique targets pesticide-resistant insects
...ck moth. The invention relies on the use of enzyme inhibitors
such as piperonyl butoxide (PBO), a natural substance derived from sesame oil. Dr Gunning said previous efforts to use PBO failed, because the pesticide was inactivated by the insect's metabolic enzymes before the inhibitor had a chance to work. Dr ...

Pushing the envelope to overcome HIV drug resistance
... resistance to currently prescribed HIV-1 protease inhibitors

Intracellular protein localization involved in new tumor progression pathway
...vivin is a member of a family of proteins that are inhibitors
of apoptosis (IAPs), but the means by which survivin inhibits apoptosis remains largely unknown. Dario Altieri and colleagues, from the University of Massachusetts Medical School, investigated the where survivin is located within the cell to see whet...

Normal cells in tumors may aid cancer growth
... Loss of genes for such factors would remove those inhibitors
and allow cancer cells to grow. "But those are only hypotheses," Eng says. "I think that the stroma plays an important role in enabling a tumor to invade neighboring tissue and spread. If that proves to be true, someone may someday develop a dr...

could act more directly, they might quench symptoms more quickly. Patients could carry PKC inhibitors
and take them preventively, as soon as they sense a manic episode coming on." Clinical trials of a P...
Elevated inflammatory enzyme, Lp-PLA2, significantly linked to ischemic stroke
...SmithKline (GSK) is actively investigating Lp-PLA2 inhibitors
and the role they may play in further reducing the risk of stroke and coronary heart disease. Lp-PLA2 is an enzyme that helps process a form of low-density lipoprotein, or "bad," cholesterol (LDL-C) into products within atherosclerotic plaques and p...
Drug may hinder recovery from heart attacks
Some new generation COX-2 inhibitors
