Does down-regulation of microRNA-26a and up-regulation of microRNA-27a contribute to aggressive progression of human osteosarcoma?
In conclusion, our findings suggested that expression level of miR-26a and miR-27a contributes to aggressive progression of this malignancy. Therefore, may have clinical potentials as a non-invasive diagnostic/prognostic biomarker for osteosarcoma patients.
This study indicates that HUCs originating from small tissue biopsies can be cultured in several passages in vitro and could have potential in repairing or restoring urinary tract tissue by tissue engineering therapy. HUCs serve as a good in vitro test platform, as shown by analysing E2-treated HUCs. E2 induced the proliferation of cultured HUCs even though concentration dependency was not observed. The findings of this study may have relevance in determining the mechanisms of estrogen therapy in postmenopausal urinary tract symptoms and in the future development of tissue engineering technology.
