ABSTRACT
Objective To analyze mRNA and protein expressions of plasminogen activator and plasminogen activator inhibitor-1 using microdissection and quantitative real-time PCR,and to analyse their associations with microvascular diseases in IgA nephropathy.Methods Twenty-four IgA nephropathy patients treated in Kidney Center and Kidney Laboratory of PLA from 2000 to 2004 were admitted into the study;20 renal glomeruli or 200 renal tubules and peritubular interstitial per patient were captured by Laser Microdissection System from IgA nephropathy renal biopsy slides(8 ?m),and mRNA was extracted.PA mRNA and PAI-1 mRNA levels in glomerulus and tubulointerstitial area were measured by Taqman quantitative real-time PCR.Capillaries densities in glomerulus and tubulointerstitial area were measured using immunohistological staining method and computer image analysis system.Results With the aggravation of lesions,the glomeruli and peritubular capillaries densities of IgA nephropathy decreased.The glomerular and peritubular capillaries densities were negatively associated with the level of serum creatinine(R2=0.6946 and R2=0.6271,P
