The relationship of expression of nuclear factor kappab gene and MMP-2mRNA and with lymph node metastasis of pancreatic cancer / 中国普通外科杂志

ABSTRACT

Objective To study the relationship of expression of nuclear factor kappab gene and MMP-2mRNA and with lymph node metastasis of pancreatic cancer.Methods The expression of NF-?B was investigated by Western blot in normal pancreatic(NP) samples of 9 cases and pancreatic cancer(PC) samples of 45 cases(lymph node metastasis 30 cases,non-lymph node metastasis 15 cases).The expression of MMP-2mRNA was detected through semiquantitative reverse transcriptase polymerase chain reaction(RT-PCR).Results Of 45 PC cases,the positive expression rate of p65 and MMP-2mRNA was 66.7%(30/45) and(57.7%)(26/45),respectively.Of 30 cases of lymph node metastasis,the positive expression rate of p65 and MMP-2mRNA was 83.3%(25/30)and 73.3 %(22/30),respectively.Of 15 cases of non-lymph node metastasis,the positive expression rate of p65 and MMP-2mRNA is 33.3%(5/15) and 26.7%(4/15),respectively,and the expression of p65 gene was positively correlated with MMP-2mRNA(expression)(r=0.743,P
