Abstract
Differential gene expression was investigated in neutrophils stimulated with N-formyl-methionyl-leucyl-phenylalanine using RNA fingerprinting by arbitrarily primed polymerase chain reaction (RAP-PCR). The cells were isolated from 3 groups of subjects: patients with generalized aggressive periodontitis (Aggressive-P. n = 6), generalized chronic periodontitis (Chronic-P, n = 6) and healthy controls (H, n = 8). Our results show that 37 genes were upregulated. while 27 genes were down-regulated in all Aggressive-P neutrophils by using RAP-PCR with 45 primer pairs. Reverse transcription-PCR analyses revealed that mRNA levels were significantly different (p<0.05) for heat shock transcription factor 4b (HSF4b) gene. Kruppel-like zinc finger transcription factor 9 (Zf9) and muskelin genes. HSF4b was greater in neutrophils from Aggressive-P compared to groups H and Chronic-P. Zf9 and muskelin genes were lower in Aggressive-P compared to the H groups, but no significant difference was noted compared to the Chronic-P group. The control genes, IL-1beta and VEGF genes, were expressed at a significantly higher level in Aggressive-P and Chronic-P than H (p<.01, p<0.05). In conclusion, the RAP-PCR technique used in this study enabled us to identify 3 Aggressive-P related genes, which had not been reported previously. Neutrophil functions in Aggressive-P patients are suggested to be altered by regulatory factors of the immune system including HSF4b (transcription factor), Zf9 (activator of TGF-beta) and muskelin (cellular adhesion).
