Abstract
BACKGROUND AND OBJECTIVES : Lysyl oxida se propeptide is secreted as a 50
kDa pro-enzyme into extracellular matrix where it is cleaved into 30-kDa mature enzyme
(LOX) and 18 kDa pro-peptide (LOX-PP) . The role of LOX enzyme in extracellular
matrix maturation has been extensively studied and linked to cross-linking of collagen
and elastin molecules. Previous studies have indicated that LOX-PP acts as a tumor
suppressor by observing its effect on transformed and malignant cell lines. Here we
investigate the effect of LOX-PP on stromal cell proliferation and differentiation towards
osteoblasts or osteoclasts and its interference with prostate cancer cell induced alterations
on proliferation and differentiation of bone marrow stromal cells.
MATERIALS AND METHODS: Bone marrow stromal cell cultures were generated
from the femur and tibia of adult 8-10 week old CD- I male mice. Cells were treated with
rLOX-PP or prostate cancer conditioned medium in the presence and absence of rLOXPP.
Lysozyme was used in the control as well as the treatment group and used as a [TRUNCATED]
