XIE Xiong, XIE Bin, RAO Bin, et al. Effect of Qingzao Jiufei Tang Expression on EGFR,NF-B,ICAM-1 and Protein Phosphorylation of JAK1 and STAT1 of Lewis Lung Cancer in Rats[J]. Chinese journal of experimental traditional medical formulae, 2016, 22(24): 140-144. DOI: 10.13422/j.cnki.syfjx.2016240140.
Objective: To observe the effect of Qingzao Jiufei Tang(QJT) on tumor weight
tumor index
nuclear transcription factor kappa B (NF-κB)
intercellular cell adhesion molecule-1 (ICAM-1)
janus kinase 1(JAK1)
epidermal growth factor receptor (EGFR) and signal transducers and activators of transcription 1 (STAT1) protein phosphorylation of Lewis lung cancer mice. Method: Totally 50 male C57BL/6J mice were randomly divided into model group
chemotherapy group[50 mg·kg-1·(2 d)-1]
and high
medium and low-dose QJT groups (15.2
7.6
3.8 g·kg-1·d-1)
with 10 in each group. The animal model was induced through the axillary injection with Lewis cells in the right arm of mice. QJT groups were intragastrically administered with medicines two weeks before modeling
chemotherapy group was intragastrically administered with cyclophosvnamide(CTX) at the corresponding dose
once every other day
and model group was intragastrically administered with the same volume of saline. At 2 weeks after modeling
the mice were put to death to weigh the tumor index
detect the expression of NF-κB by immunohistochemical method
the expression of ICAM-1 by Real-time PCR method
and JAK1
pEGFR and pSTAT1 by Western blot method. Result: Tumor weight and tumor index of high and medium-dose QJT groups and CTX group were significantly decreased
compared with the model group
with significant differences(P<0.01). CTX group
and high and medium-dose QJT groups showed significant decreases in the expression of NF-κB and EGFR protein expression (P<0.05
P<0.01)
high and medium-dose QJT groups showed significant decrease in the expressions of ICAM-1 and pJAK1 (P<0.05
P<0.01)
high
medium and low-dose QJT groups showed significant decrease in phosphorylation of STAT1
compared with the model group
with significant differences (P<0.01)
high and medium-dose QJT groups were superior to CTX group (P<0.01). Conclusion: QJT can significantly inhibit the proliferation of Lewis lung cancer cells. It may inhibit lung cancer by reducing the protein expressions of NF-κB
