Endometriosis, a common disorder affecting women of reproductive age is characterized by ectopic growth of the endometrial tissues, altered steroid hormone response and inflammation. Previous studies revealed that statins, selective inhibitors of the key step of mevalonate pathway, inhibit growth of endometrial stromal cells in vitro and reduce endometriotic lesions in murine models of endometriosis. This study evaluated the effects of simvastatin on the development of endometriosis in a baboon model of this disease...

BACKGROUND: Statins are commonly prescribed for the secondary prevention of ischemic stroke, but there is conflicting evidence as to whether they increase the risk of intracranial hemorrhage. Lipophilic statins cross the blood-brain barrier more freely than hydrophilic statins and may therefore increase the risk of intracranial hemorrhage. OBJECTIVE: To determine whether, in older patients following ischemic stroke, receipt of lipophilic statins was associated with differences in the risk of intracranial hemorrhage...

Xuenian Huang, Yajing Liang, Yong Yang, Xuefeng Lu
Monacolin J is a key precursor for the synthesis of simvastatin (Zocor), an important drug for treating hypercholesterolemia. Industrially, monacolin J is manufactured through alkaline hydrolysis of lovastatin, a fungal polyketide produced by Aspergillus terreus. Multistep chemical processes for the conversion of lovastatin to simvastatin are laborious, cost expensive and environmentally unfriendly. A biocatalysis process for monacolin J conversion to simvastatin has been developed. However, direct bioproduction of monacolin J has not yet been achieved...

OBJECTIVE: Atherosclerosis is a chronic inflammatory condition and is one of the main causes of death worldwide. Macrophages play important roles in the formation of atherosclerotic plaques. Apoptosis is progressively observed while plaques develop, although the precise mechanisms and outcomes of apoptosis in atherosclerosis development and progression are still contradictory. This study was conducted to explore the effects of simvastatin and retinoic acid receptor-related orphan receptor alpha (RORα) ligands on apoptosis in human acute monocytic leukemia (THP-1) macrophage cells...

The recessive N-ethyl-N-nitrosourea-induced phenotype toku is characterized by delayed hair growth, progressive hair loss, and excessive accumulation of dermal cholesterol, triglycerides, and ceramides. The toku phenotype was attributed to a null allele of Gk5, encoding glycerol kinase 5 (GK5), a skin-specific kinase expressed predominantly in sebaceous glands. GK5 formed a complex with the sterol regulatory element-binding proteins (SREBPs) through their C-terminal regulatory domains, inhibiting SREBP processing and activation...
