Activated growth factor receptor tyrosine kinases (RTK) play pivotal roles in a variety of human cancers, including breast cancer. Ron, a member of the Met RTK proto-oncogene family, is overexpressed or constitutively active in 50% of human breast cancers. To define the significance of Ron overexpression and activation in vivo , we generated transgenic mice that overexpress a wild-type or const...

We present a novel technique, dubbed FiEstAS, to estimate the underlying density field from a discrete set of sample points in an arbitrary multidimensional space. FiEstAS assigns a volume to each point by means of a binary tree. Density is then computed by integrating over an adaptive kernel. As a first test, we construct several Monte Carlo realizations of a Hernquist profile and recover the ...

protecting the environment is becoming one of the most important concerns of the developed and developing countries. reclamation of msw landfills, which are sources of many pollutants including leachate and greenhouse gases, would be very valuable in saving the resources and reducing the pollution scale. in the current article the potential for use of reclaimed waste in rdf production has been ...

Neurodegeneration is a critical problem in aging populations and is characterized by severe central nervous system (CNS) inflammation. Macrophages closely regulate inflammation in the CNS and periphery by taking on different activation states. The source of inflammation in many neurodegenerative diseases has been preliminarily linked to a decrease in the CNS M2 macrophage population and a subse...

Overexpression of the RON receptor tyrosine kinase contributes to pathogenesis of epithelial cancers and disruption of RON signals has potential for therapeutic intervention. Here, we report the inhibitory effects of monoclonal antibodies (Zt/g4, Zt/f2 and Zt/c9) on RON expression and tumorigenic activities in colon cancer cells. Persistent treatment of colon SW620 or other cells with Zt/g4 dra...

BACKGROUND Glucocorticoids (GCs) are used in ~ 60% of patients with rheumatoid arthritis (RA). Although disease-modifying, they also have significant adverse effects. Understanding factors associated with GC use may help minimise exposure. The aims of the present study were to describe oral GC use in RA; determine any change in use over time; and determine factors associated with oral GC use, c...

To determine if people who expect a recall (RCL) test encode a list of to-beremembered (TBR) words differently than those who expect a recognition (RON) test, people were first induced to expect a RCL or a RON test and then were asked to remember a critical list consisting of both high-frequency (HF) and low-frequency (LF) words. Following presentation of the critical list, different groups rec...

Ron is a human receptor for the macrophage-stimulating protein (MSP). Exon 11 skipping of Ron pre-mRNA produces the Ron∆165 protein that has a deletion of a 49 amino acid region in the β-chain extracellular domain. Ron∆165 is constitutively active even in the absence of its ligand. Through stepwise deletion analysis, we identified a 2-nt RNA enhancer, which is located 74 nt upstream from the 5'...

The MSP/RON signaling pathway favors the conversion of micrometastatic lesions to overt metastases by suppressing antitumor immune responses. The loss of RON functions in the host potentiates tumor-specific CD8+ T-cell responses, hence inhibiting the outgrowth of metastatic cancer cells. Thus, RON inhibitors may potentially prevent the outgrowth of micrometastases in cancer patients.
