Summary
The majority of tumor death occurs due to tumor metastasis. Both tumor growth and tumor spread require angiogenesis, which is thought to be driven by tumor but originated from host endothelial cells. Could tumor cells behave and function like endothelial cells? This application aims to detect the transition of adult epithelial cells to endothelial cells through a transient mesenchymal state. Our studies should reveal both the molecular and cellular causes of vasculogenic mimicry, thus establishi ....The majority of tumor death occurs due to tumor metastasis. Both tumor growth and tumor spread require angiogenesis, which is thought to be driven by tumor but originated from host endothelial cells. Could tumor cells behave and function like endothelial cells? This application aims to detect the transition of adult epithelial cells to endothelial cells through a transient mesenchymal state. Our studies should reveal both the molecular and cellular causes of vasculogenic mimicry, thus establishing a new paradigm in understanding tumor growth and metastasis. Such novel molecular understanding will open up new anti-tumor therapeutic opportunities.Read moreRead less

Summary
Cytokines are hormone like messengers that mediate the interactions between cells. We have discovered a new cytokine that we have named macrophage inhibitory cytokine 1 (MIC-1). It belongs to a very important family of proteins that are involved in wound healing, development and inflammation. Our data thus far suggests that MIC-1 is an anti-inflammatory factor that is of particular relevance in rheumatoid arthritis. We wish to determine the relationship between the amount of this cytokine in the ....Cytokines are hormone like messengers that mediate the interactions between cells. We have discovered a new cytokine that we have named macrophage inhibitory cytokine 1 (MIC-1). It belongs to a very important family of proteins that are involved in wound healing, development and inflammation. Our data thus far suggests that MIC-1 is an anti-inflammatory factor that is of particular relevance in rheumatoid arthritis. We wish to determine the relationship between the amount of this cytokine in the joint and the blood and the activity of rheumatoid arthritis. To better understand the actions of this molecule, we also want to study the factors that regulate the production of MIC-1 from human blood cells. Finally, to assess whether MIC-1 is useful for the treatment of rheumatoid arthritis, we will use gene therapy approaches to develop animals that produce increased amounts of MIC-1 and determine whether this prevents or mitigates the development of rheumatoid arthritis.Read moreRead less

We have discovered a new cytokine that we have named macrophage inhibitory cytokine 1 (MIC-1). It belongs to a very important familty of proteins that are involved in wound healing, development and inflammation. Our data thus far suggest thatMIC-1 is an antiinflammatory factor that also involved in reproduction, especially in the health of the placenta. To determine the accuracy of these predictions we wish to use genetic techniques to delete this gene from a mouse. Study of this genetically modified mouse will give us a great deal of information on the most important roles of MIC-1.Read moreRead less
A New Mechanism Of Tissue Fibrosis - A Small Peptide Regulator Of The TGF-beta1/Smad Pathway

Summary
Progressive scarring, or fibrosis, of organs leads to their loss of function. Fibrotic diseases are devastating to both the individual and our community and we lack effective therapies. We have identified a small protein, named SPRF, which represents a new mechanism in tissue fibrosis. These studies will examine the role of the SRPF protein in models of kidney, heart and lung fibrosis and its underlying mechanism of action. We will also test a therapy based on inhibiting SPRF function.
