Abstract:
Objective To investigate mRNA expression levels of cathepsin B,cathepsin L and uPA in non-Hodgkin lymphoma (NHL) samples,and analyze the relationship between three genes and clinicopathological factors.Methods Real-time fluorescence quantitative RT-PCR was used to quantify the relative expression levels of cathepsin B,cathepsin L and uPA mRNA in 39 NHL patients without chemotherapy or radiotherapy and 15 patients with lymph node reactive hyperplasia.Relationship between their expression and clinico-pathological factors was analyzed.Results mRNA expression levels of cathepsin B,cathepsin L and uPA in NHL group were significantly higher than those in the control group (0.403 vs 0.128,0.209 vs 0.057,0.459 vs 0.031,all P ＜ 0.05).The mRNA expression levels of cathepsin B,cathepsin L and uPA were correlated with each other in NHL.The mRNA expression levels of cathepsin B,cathepsin L and uPA in advanced staged NHL were markedly higher than those in early staged NHL (0.453 vs 0.341,0.204 vs 0.085,0.372 vs 0.196,all P ＜ 0.05).mRNA levels of cathepsin B,cathepsin L and uPA were higher in NHL patients sensitive to chemotherapy than in those resistant to chemotherapy(0.401 vs 0.556,0.085 vs 0.205,0.316 vs 0.499,all P ＜ 0.05).Conclusions The high expression of cathepsin B,cathepsin L and uPA could be detected in NHL,and their expression has a close relationship with the biological behavior characters of NHL.The dynamic examination of cathepsin B,cathepsin L and uPA may be used as clinical auxiliary diagnosis and prognosis of NHL.
