EBV, an oncogenic human herpesvirus, can transform primary B lymphocytes into immortalized lymphoblastoid cell lines (LCLs) through multiple regulatory mechanisms. However, the involvement of protein tyrosine kinases in the infinite proliferation of B cells is not clear. In this study, we performed kinase display assays to investigate this subject and identified a specific cellular target, Rece...
Cell invasion is one of crucial reasons for cancer metastasis and malignancy. Recepteur d'origine Nantais (RON) has been reported to play an important role in the cancer cell invasion process. High accumulation and activation of RON has been implicated in gastric adenocarcinoma AGS cells. Chrysin is a naturally occurring phytochemical, a type of flavonoid, which has been reported to suppress tu...
Current Biology 25, R301–R327, April 20, 2015 hosts to the many students and visitors who passed through the lab, and his administrative assistant of many years, Mary Hilda Counselman, personally took care of generations of students as we arrived. In my case, she helped me move out of a hotel in an unsavory section of town to better accommodations and later lent her own furniture to me and my w...
Recepteur d' origine nantais (RON), a tyrosine kinase receptor, is aberrantly expressed in human tumors and promotes cancer cell invasion. RON receptor activation is also associated with resistance to tamoxifen treatment in breast cancer cells. Nrf2 is a positive regulator of cytoprotective genes. Using chromatin immunoprecipitation (ChIP) and site-directed mutagenesis studies of the RON promot...
The RON receptor tyrosine kinase and its ligand macrophage stimulating protein (MSP) play a role in epithelial tumorigenesis. We report here a novel RON variant that antagonizes the RON-MSP pathway in various cancer cells. The variant is an 85 kDa soluble protein from an mRNA transcript with an insertion of 49 nucleotides between exons 5 and 6. The insertion created a stop codon leading to the ...
Ron receptor kinase (MST1R) is important in promoting epithelial tumorigenesis, but the potential contributions of its specific expression in stromal cells have not been examined. Herein, we show that the Ron receptor is expressed inmouse and human stromal cells of the prostate tumormicroenvironment. To test the significance of stromal Ron expression, prostate cancer cells were orthotopically i...
The RON receptor tyrosine kinase is a 180 kDa heterodimeric protein composed of a 40 kDa alpha chain and a 145 kDa beta chain with intrinsic tyrosine kinase activity. Activation of RON causes cell dissociation, motility and invasion of extracellular matrices, suggesting that RON might be involved in tumor metastasis. We report here the cloning of a novel splice variant of RON in human colorecta...
Inflammatory bowel diseases (IBD) are chronic inflammatory disorders of the intestine that result in painful and debilitating complications. Currently no cure exists for IBD, and treatments are primarily aimed at reducing inflammation to alleviate symptoms. Genome-wide linkage studies have identified the Ron receptor tyrosine kinase (TK) and its ligand, hepatocyte growth factor-like protein (HG...
BACKGROUND Macrophage stimulating protein (MSP) is a serum growth factor that binds to and activates the receptor tyrosine kinase, Recepteur d'Origine Nantais (RON). A non-synonymous coding variant in MSP (689C) has been associated with genetic susceptibility to both Crohn's disease and ulcerative colitis, two major types of inflammatory bowel disease (IBD) characterized by chronic inflammation...
The RON receptor tyrosine kinase regulates the balance between classical (M1) and alternative (M2) macrophage activation. In primary macrophages, the ligand for Ron, macrophage-stimulating protein (MSP), inhibits the expression of inducible NO synthase, a marker of classically activated macrophages, whereas promoting the expression of arginase I, a marker of alternative activation. Ron(-/-) mic...
