title: Expression of heparan sulfate proteoglycan mRNA in rat kidneys during calcium oxalate nephrolithiasis.
abstract: This study used reverse transcription polymerase chain reaction (RT-PCR) to examine heparan sulfate proteoglycan (HS-PG) mRNA expression levels during stone formation in the rat kidney. Total RNA in kidneys was extracted and converted to cDNA. PCR products were resolved by electrophoresis on 1.5% agarose gel and visualized with ethidium bromide. Fragment intensity and area were measured using an image analyzer. Control cyclophilin and HS-PG mRNAs were expressed in all samples examined as 235 bp and 506 bp bands, respectively. Cyclophilin expression in the normal group was not significantly different from expression in the group that formed stones. However, the level of HS-PG mRNA expression apparently increased in calcium oxalate (CaOx) microlith. The findings suggest an association between CaOx nephrolithiasis and expression of HS-PG in the rat kidney.
