[The cloning and expression of apoptosis associated gene ANNEXIN A2 induced by p53 gene].
OBJECTIVE
To identify the relationship between p53-dependent apoptosis associated genes and tumor metastasis.


METHODS
mRNA differential display (mRNA DD) was adopted for gene cloning after the different metastatic potential lung cancer cell lines were infected by Adv-p53 (a reconstructed adenovirus encoding wild type p53 gene). RT-PCR, Northern blot and Western blot assays were used to confirm the result from mRNA DD.


RESULTS
After induction by p53 gene, the ANNEXIN A2 gene had differential expression in the cell lines; its level was down regulated in all the cells infected by Adv-p53 gene, especially in the Anip973 cell lines with high metastatic potential. RT-PCR, Northern blot and Western blot assays confirmed the consequence.


CONCLUSIONS
The experimental data suggest that the ANNEXIN A2 gene may relate to cellular apoptosis induced by p53 gene. The affirmative relationship between ANNEXIN A2 gene and p53 needs further investigation.
