Immunohistochemical demonstration of a mRNA-transport protein in rat liver putative preneoplastic foci.

abstract：:Midkine (MK) is a heparin binding growth factor identified as a product of a retinoic acid-responsive gene; it is frequently expressed at high levels in many human carcinomas. Although the expression of the mRNA encoding truncated MK (tMK) in unique human cancer cells has been reported, the tMK polypeptide itself has ...

abstract：:Multidrug resistance (MDR) is a serious obstacle for cancer chemotherapy. The aim of this study was to reverse MDR of breast carcinoma cells specifically by degrading mdr1 mRNA with anti-mdr1 ribozyme. Our strategy was to limit the expression of ribozyme to only breast-derived cells, but not other type of cells. The r...
