The research progress of MMP-2 with papillary thyroid carcinoma
Treatment of prognosis of papillary thyroid carcinoma although the better,but it is also a malignant tumor inva sion and metastasis of biological characteristics.MMPs in tumor invasion and metastasis played an important role,especial ly its family members of the MMP-2(matrix metalloproteinase-2 or gelatinase) the study,suggesting that in papillary thy roid carcinoma showed a high positive,high-level expression of benign lesions have statistically significant difference.In recent years with MMP-2 in thyroid diseases studied literature at home and abroad reported an overview of MMP-2 in thyroid papillary carcinoma of the research situation,look to the future research directions.
LTXBO mice develop ovarian teratomas at high frequency. The phenotype of tumour tissues is unusual in that most contain trophoblast elements. Since the tumours are derived from parthenogenetically activated oocytes, they would not be expected to produce trophoblast. The developmental potential of parthenogenetic cells from these mice was tested in aggregation chimeras. No contribution to trophoblast tissues was observed. However, a high incidence of morphological abnormalities was seen, suggesting that the parthenogenetic cells exerted a teratogenic effect.
