Identification of Novel Agents for the Treatment of Brain Metastases of Breast Cancer.

BACKGROUND: Brain cancer from metastasized breast cancer has a high mortality rate in women. The treatment of lesions is hampered in large part by the blood-brain barrier (BBB), which prevents adequate distribution of anti-cancer compounds to brain…

Osteoactivin (GPNMB) ectodomain protein promotes growth and invasive behavior of human lung cancer cells.

The potential application of GPNMB/OA as a therapeutic target for lung cancer will require a greater understanding of the impact of GPNMB/OA ectodomain (ECD) protein shedding into tumor tissues. Thus, in this work we characterized GPNMB/OA expression…

The anabolic effects of vitamin D-binding protein-macrophage activating factor (DBP-MAF) and a novel small peptide on bone.

Vitamin D-binding protein-macrophage activating factor (DBP-MAF) has previously been shown to stimulate bone resorption and correct the skeletal defects associated with osteopetrosis in two nonallelic mutations in rats. This same protein and a small…

Parkinson's disease biomarker: a patent evaluation of WO2013153386.

INTRODUCTION: Parkinson's disease (PD) is a neurodegenerative movement disorder resultant from the loss of dopaminergic neurons in the brain. There is an urgent need for effective biomarkers that can be used in the early diagnosis of PD.…

Integrin mediated adhesion of osteoblasts to connective tissue growth factor (CTGF/CCN2) induces cytoskeleton reorganization and cell differentiation.

Pre-osteoblast adhesion and interaction with extracellular matrix (ECM) proteins through integrin receptors result in activation of signaling pathways regulating osteoblast differentiation. Connective tissue growth factor (CTGF/CCN2) is a…

Emerging lung cancer therapeutic targets based on the pathogenesis of bone metastases.

Lung cancer is the second most common cancer and the leading cause of cancer related mortality in both men and women. Each year, more people die of lung cancer than of colon, breast, and prostate cancers combined. It is widely accepted that tumor…

Mutation in Osteoactivin Promotes Receptor Activator of NFkappaB Ligand (RANKL)-mediated Osteoclast Differentiation and Survival but Inhibits Osteoclast Function.

We previously reported on the importance of osteoactivin (OA/Gpnmb) in osteogenesis. In this study, we examined the role of OA in osteoclastogenesis, using mice with a nonsense mutation in the Gpnmb gene (D2J) and wild-type controls (D2J/Gpnmb(+)).…

Osteoactivin inhibition of osteoclastogenesis is mediated through CD44-ERK signaling.

Osteoactivin is a heavily glycosylated protein shown to have a role in bone remodeling. Previous studies from our lab have shown that mutation in Osteoactivin enhances osteoclast differentiation but inhibits their function. To date, a classical…
