RESUMEN
Objective To investigate the p33~ ING1b mRNA level and the relationship to clinical pathological data in primary hepatocellular carcinoma(PHC).Methods Reverse transcriptase-polymerase chain reaction (RT-PCR) method was employed to detect the mRNA level of p33~ ING1b in liver cancer tissues and adjacent tissues of cancer.Results p33~ ING1b mRNA was positive expression in 63.6% (35/55) cancer tissues and 70.9% (39/55) adjacent tissues of cancer.The expression level of p33~ ING1b mRNA in cancer tissues (0.410?0.175) was significantly lower than that in adjacent tissues of cancer (0.529?0.203). The level of p33~ ING1b was significantly associated with pathological grades, lymph node metastasis and envelope infiltration, but not associated with sex, age, tumor size, tumor thrombus or liver cirrhosis.Conclusion The decrease of p33~ ING1b may play an important role in the tumorigenesis and development of PHC, and may be an adjuvant parameter in evaluating tumor differentiation, invasion and prognosis.
