THE CLINICAL STUDY ON PRODUCTION AND mRNA EXPRESSION OF TGFβ IN CHILDREN NEPHROTIC
SYNDROME Yu Li, Zhuo M-Y, Yang X-S,
Zhong Z-M Department of Pediatrics, Guangzhou First People’s Hospital, Guangzhou, China Objective: In order to investigate the clinical significance of the transforming
growth factorβ(TGFβ) production and mRNA expression in children nephrotic syndrome . Methods: In 7 boys and 11 girls with primary nephrotic syndrome, TGFβprotein was detected by
ELISA method in serum and peripheral blood monoeuclear cell(PBMC)
cultured liquid. Endotoxin-induced
TGFβmRNA expression in PBMC was measured by reverse transcription
polymerase chain reaction (RT-PCR) method. 18 case (13 girls and 5 boys,
health children) as control group. Results: The results were expressed as: (1)TGFβ protein level was higher
in children with nephrotic syndrome than control group especially in PBMC
cultured liquid, in serum 33.68±17.31 vs 16.35±3.28, p<0.05; in PBMC
cultured liquid 143.88±12.51 vs 26.24±5.34 p<0.01; (2)TGFβmRNA expression increased
in nephrotic syndrome children group, 4.85±1.01 vs 0.04±0.01, p<0.05. Conclusion: Our findings suggest that the TGFβmRNA expression and TGFβmight play an important role in pathological mechanism of children nephrotic syndrome. |
