Ewing sarcoma is the second most common bone malignancy in children and young adults. It is driven by oncogenic fusion proteins (i.e. EWS/FLI1) acting as aberrant transcription factors that upregulate and downregulate target genes, leading to cellular transformation. Thus, identificating these target genes and understanding their contribution to Ewing sarcoma tumorigenesis are key for the devel...
The gene encoding lysyl oxidase (LOX) was identified as the ras recision gene (rrg), with the ability to revert Ras-mediated transformation of NIH 3T3 fibroblasts. Mutations in RAS genes have been found in f25% of lung cancers and in 85% of pancreatic cancers. In microarray analysis, these cancers were found to display reduced LOX gene expression. Thus, the ability of the LOX gene to repress th...
This study investigated the role of LOX in promoting invasion and metastasis of epithelial ovarian cancer in a hypoxic environment and its specific signal transduction pathway. Immunohistochemical detection of HIF-1α and LOX protein expression was performed on formalin-fixed paraffin sections of normal ovary, benign ovarian tumors, borderline and malignant epithelial ovarian tumor paraffin samp...
The proinflammatory enzyme 5-lipoxygenase (5-LOX) is upregulated in Alzheimer's disease (AD), but its localization and association with the hallmark lesions of the disease, beta-amyloid (Abeta) plaques and neurofibrillary tangles (NFTs), is unknown. This study examined the distribution and cellular localization of 5-LOX in the medial temporal lobe from AD and control subjects. The spatial relat...
Lysyl oxidase (LOX), an extracellular amine oxidase, catalyzes the cross-linking of collagen and elastin. LOX has been also shown to play an essential role in promoting the invasive and metastatic potential of breast tumor cells. However, the LOX-interacting factors in these processes are not known. In this study, we identified placental lactogen (PL), a member of the growth hormone/prolactin h...
Lysyl oxidase (LOX) has been reported to regulate tumor metastasis and has been found to involve in modification of extracellular matrix (ECM) in the context of tumorigenesis. The aim of this study is to determine the prognostic significance of LOX in non-small cell lung cancer (NSCLC) patients and to examine the correlation between LOX expression and ECM remodeling-associated MMP2/MMP9 in NSCL...
BACKGROUND Soluble lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) level is a novel biomarker for diagnosis of acute coronary syndrome (ACS); however, this level in the coronary circulation has yet to be examined. METHODS Twenty-seven consecutive patients with ACS and 40 patients with effort angina pectoris (EAP) undergoing percutaneous coronary intervention (PCI) had levels o...
STAT3 is a ubiquitous transcription factor that is indispensable during early embryogenesis. To study the functions of STAT3 postnatally, we generated conditional STAT3-deficient mice. To that end, STAT3(lox/lox) mice were crossed with mice expressing Cre under the control of rat insulin II gene promoter (RIP-Cre mice). Immunohistochemical and Western blot analyses showed that STAT3 is deleted ...
New studies of the relationship between polyunsaturated fatty acid metabolismand carcinogenesis have led to novel molecular targets for cancer chemoprevention research. These targets include procarcinogenic lipoxygenases (LOXs), including 5-, 8-, and 12-LOX, and anticarcinogenic LOXs, including 15-LOX-1 and possibly 15-LOX-2. Recent studies indicate that 15-LOX-1 is down-regulated in colorectal...
BACKGROUND We have recently demonstrated a lectin-like receptor for oxidized (ox)-LDL (LOX-1) in human coronary artery endothelial cells (HCAECs). This receptor is upregulated by ox-LDL. The present study examined the significance of LOX-1 in monocyte adhesion to HCAECs and endothelial injury in response to ox-LDL. METHODS AND RESULTS HCAECs were incubated in the presence of antisense oligode...
