Abstract
Importance of the field: Proprotein convertase subtilisin kexin 9 (PCSK9) is a new actor discovered in 2003 that is implicated in autosomal dominant hypercholesterolemia, cholesterol homeostasis and coronary heart disease. It has been shown to degrade the low-density lipoprotein (LDL) receptor independently of its catalytic activity. Several pharmacological strategies to reduce PCSK9 are being thoroughly investigated.
Areas covered in this review: This article reviews all different strategies that are presently pursued to modulate the functional activity of PCSK9 which is a prime target for controlling LDL-cholesterol. It also provides a briefing of all the patents up to July 2010 from various organizations including pharmaceutical companies and academic institutions that have been submitted and/or approved.
What the reader will gain: This review is addressed to researchers from academia and pharmaceutical companies who are engaged in PCSK9 research/cholesterol regulation and in the development of cholesterol lowering drugs. Readers will gain an up-to-date overview of the different strategies that have been investigated to reduce PCSK9 including antisense technology and specific antibodies.
Take home message: Clinical trials have been launched using RNA interference approaches to reduce PCSK9 expression or specific antibodies targeting and inhibiting PCSK9 interaction with the LDL receptor. They constitute very promising approaches to reducing cholesterol levels and coronary heart disease.
