Abstract:
OBJECTIVE:To observe growth inhibition effect of perlecan anti-sense cDNA (pAP) on human laryngeal carcinoma xnografted in nude mice. To vertify its antitumor effect and mechanism in vivo, and it may be useful as a biomarker in carcinoma of larynx cancer.
METHOD:Created the model of human laryngeal carcinoma xnograft in nude mice. To observe growth of those xnografts in nude mice and draw growth curve of xnografted. The expression of perlecan mRNA and portein in xnografts were examined by RT-PCR and immunohistochemistry.
RESULT:Volume of xnografts in the group transfected by the plasmids of pAP were significant small as compared with other two groups made by the wild type cells and phpApr-neol cells (P < 0.05). It was showed that the expression of perlecan mRNA and protein were significantly reduced in the tumor of pAP transfected Hep-2 cells as compared with the tumors transfected by the wild type cells and phβApr-neol cells (P < 0.01).
CONCLUSION:These data raise the possibility that pAP many play key roles in the growth of those xnografts in nude mice.
