The present study aimed to determine whether the expression of lectin-like oxidized LDL receptor 1 (LOX-1) could be induced by oxidized low-density lipoprotein (Ox-LDL) and interleukin 1β (IL-1β) in human mesangial cells (HMCs). Oil Red O staining was used to observe the uptake of Ox-LDL by HMCs stimulated with IL-1β, and reverse transcription-quantitative polymerase chain reaction analysis and...

Prostate cancer is a devastating disease for which current therapies are inadequate. Various lines of evidences have suggested the 5-lipoxygenase (5-LOX) pathway and the leukotriene receptor pathway are potential targets for prevention or treatment of Prostate cancer. Thus, search for new anti-cancer drugs targeting 5-LOX and leukotriene is very essential and important. The objective of the pre...

AIMS LOX-1 is a major vascular receptor for oxidized low-density lipoprotein (oxLDL). In this study, we analysed the impact of LOX-1 overexpression and high dietary fat intake on vascular function in small resistance arteries. METHODS AND RESULTS Relaxation of mesenteric arteries was measured using a wire myograph. Compared with the control group, mice overexpressing LOX-1 on a high-fat diet ...

Lysyl oxidase (LOX), a matrix cross-linking protein, is known to be selectively expressed and to enhance a fibrotic phenotype. A recent study of ours showed that LOX oxidizes the PDGF receptor-β (PDGFR-β), leading to amplified downstream signaling. Here, we examined the expression and functions of LOX in megakaryocytes (MK), the platelet precursors. Cells committed to the MK lineage undergo mit...

Oxidized low density lipoprotein (Ox-LDL) induces apoptosis in vascular smooth muscle cells (VSMCs), which may increase atherosclerotic plaque instability. In this study, we examined the molecular mechanisms causing the Ox-LDL-induced apoptosis in VSMCs, especially focusing on the involvement of Bax/Bcl-2 and the lectinlike Ox-LDL receptor-1 (LOX-1). In cultured bovine aortic smooth muscle cell...

OBJECTIVE LOX-1, a receptor for oxidized low-density lipoprotein, plays a critical role in atherosclerosis. Its expression is upregulated by pro-atherogenic stimuli, such as angiotensin II (Ang II). In this study, we explored LOX-1 transcriptional promoter activation in response to Ang II in human coronary artery endothelial cells (HCAECs). METHODS AND RESULTS We constructed full-length and d...

Abstract To test the hypothesis that poor maternal nutrition during gestation would alter offspring muscle shear force and adipogenesis, fibrogenesis, myogenesis mRNA expression, Dorset ewes (n=46) pregnant with twins were fed 100%, 60% or 140% of NRC requirements from d30±0.02 until parturition. Male CON (n=12), OVER (n=13), RES (n=21) euthanized at d284±1.82 longissimus (LM) was harvested for...

Improved antigenicity against HIV-1 envelope (Env) protein is needed to elicit vaccine-induced protective immunity in humans. Here we describe the first tests in non-human primates (NHPs) of Env gp140 protein fused to a humanized anti-LOX-1 recombinant antibody for delivering Env directly to LOX-1-bearing antigen presenting cells, especially dendritic cells (DC). LOX-1, or 1ectin-like oxidized ...
