MST-312 has been used in cell invasion assay using mouse fibroblast cells (NIH-3T3) and in the co-immunoprecipitation experiments in colon fibroblast.
Biochem/physiol Actions
MST-312 is a telomerase Inhibitor.
MST-312 is a telomerase Inhibitor. Telomeres are nucleoprotein complexes present on the ends of chromosomes, containing DNA segment tandem repeats that shorten with each repetitive cell cycle. Telomere shortening leads to loss of function, resulting in cell senescence and limited survivability. The reverse transcriptase, telomerase, maintains telomere length and function in immortalized cell lines and most cancer cell lines, and telomerase activity is associated with tumorigenesis. Telomere elongation is also believed to be an important contributor to the genomic stability and indefinite self renewal of iPS cells. 1 μM MST-312 was shown to effectively reduce telomere length and inhibit proliferation in U937 cells.
RNA and DNA guanine-rich sequences can adopt unusual structures called Guanine quadruplexes (G4). A quadruplex-prone RNA sequence is present at the 5'-end of the 451-nt-long RNA component of telomerase, hTERC. As this quadruplex may interfere with P1 helix formation, a
Combination treatment with flavonoid morin and telomerase inhibitor MST-312 reduces cancer stem cell traits by targeting STAT3 and telomerase.
