Distinguishing tumor cells via analyzing intracellular telomerase activity.
Two strategies to identify tumor cells were developed in this research via analyzing the activity of telomerase inside the cells, which is regarded as the mark enzyme of tumors. The lysate of cells was used to assay directly. In the electrochemical assay, the substrate of telomerase was incubated with the lysate, followed by PCR amplification of the elongated products. Then the oxidation peak c...
متن کاملNanocurcumin-Mediated Down-Regulation of Telomerase Via Stimulating TGFβ1 Signaling Pathway in Hepatocellular Carcinoma Cells
Background: Curcumin, extracted from turmeric, represents enormous potential to serve as an anticancer agent. Telomerase is viewed as a prominent molecular target of curcumin, and transforming growth factor-β1 (TGFβ1) has proven to be a major inhibitory signaling pathway for telomerase activity. In the current study, we aimed to explore suppressive effects of nanocurcumin on telomeras...
متن کاملSmart vesicle kit for in situ monitoring of intracellular telomerase activity using a telomerase-responsive probe.
A smart vesicle kit was designed for in situ imaging and detection of cytoplasmic telomerase activity. The vesicle kit contained a telomerase primer (TSP) and a Cy5-tagged molecular beacon (MB) functionalized gold nanoparticle probe, which were encapsulated in liposome for intracellular delivery. After the vesicle kit was transfected into cytoplasm, the released TSP could be extended in the pre...
متن کاملStudy of telomerase activity, proliferation and differentiation characteristics in umbilical cord blood mesenchymal stem cells
In recent years, considerable advances have been made in the field of regenerative medicine. Unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. It h...
متن کاملTelomerase activity in human hematopoietic progenitor cells.
BACKGROUND AND OBJECTIVE Telomerase is the enzyme that stabilizes and elongates the telomeric ends of chromosomes. It is expressed in germline and malignant cells and absent in most human somatic cells. The selective expression of telomerase has thus been proposed to be a basis for the immortality of germline and malignant cells. Recently, telomerase activity has been observed in human bone mar...
