Abstract

Oxalate rich stones are the most common among the various stones. Oxalate binding protein plays a vital role in the transport of oxalate. Nuclear pore complex (NPC) contains a protein of molecular weight 62 kDa and it has maximum oxalate binding activity. The physiological significance of the presence of oxalate binding protein in the NPC is not well understood. In order to study its function, the expression of this protein during oxalate stress condition and the morphological changes on oxalate exposure to synchronized VERO cells have been determined. VERO cells were synchronized at different stages of cell cycle using cell cycle blockers and expression of the NPC p62 was assessed using enzyme linked immunosorbent assay (ELISA) technique with p62 antibody (MAb 414). Expression of NPC p62 was more pronounced in 1.0mMoxalate concentration in mitotic phase than in S phase, suggesting cell cycle dependency. During oxalate exposure there is cell aggregation and complete degeneration of cell morphology occurs, which in turn lead to the expression of certain genes, including the NPC oxalate binding protein p62. Thus, oxalate induces degeneration of cells (may be due to the lipid peroxidation) and leads to the expression of NPC oxalate binding protein and the expression is of cell cycle dependent manner.
