Inhibition of prenyltransferase activity by statins in both liver and muscle cell lines is not causative of cytotoxicity.

As inhibitors of 3-hydroxy-3-methylglutaryl-CoA reductase, statins are an important first-line treatment for hypercholesterolemia. However, a recognized side-effect of statin therapy is myopathy, which in severe cases can present as potentially fatal rhabdomyolysis. This represents an important impediment to successful statin therapy, and despite decades of research the molecular mechanisms underlying this side-effect remain unclear.

Biomphalaria glabrata transcriptome: cDNA microarray profiling identifies resistant- and susceptible-specific gene expression in haemocytes from snail strains exposed to Schistosoma mansoni.

Background: Biomphalaria glabrata is an intermediate snail host for Schistosoma mansoni, one of the important schistosomes infecting man. B. glabrata/S.

The neuroprotective action of the mood stabilizing drugs lithium chloride and sodium valproate is mediated through the up-regulation of the homeodomain protein Six1.

The mood stabilizing agents lithium chloride (LiCl) and sodium valproate (VPA) have recently gained interest as potential neuroprotective therapeutics. However, exploitation of these therapeutic applications is hindered by both a lack of molecular understanding of the mode of action, and a number of sub-optimal properties, including a relatively small therapeutic window and variable patient response. Human neuroblastoma cells (SH-SY5Y) were exposed to 1 mM lithium chloride or 1 mM sodium valproate for 6 h or 72 h, and transcriptomes measured by Affymetrix U133A/B microarray.

Immunomodulation by herpesvirus U51A chemokine receptor via CCL5 and FOG-2 down-regulation plus XCR1 and CCR7 mimicry in human leukocytes.

Human herpesvirus-6A (HHV-6A) betachemokine-receptor U51A binds inflammatory modulators CCL2, CCL5, CCL11, CCL7, and CCL13. This unique specificity overlaps that of human chemokine receptors CCR1, CCR2, CCR3, and CCR5. In model cell lines, expression leads to CCL5 down-regulation with both constitutive and inducible signaling.
