Általános leírás

A cell-permeable, naturally isolated Ginkgo biloba biflavanoid that acts as a general pre-mRNA splicing inhibitor (ICmax = 50 µM in splicing assays using HeLa nuclear extract) by blocking the spliceosome-meidated splicing process at the prespliceosome/A complex stage. Isoginkgetin treatment is shown to result in growth arrest in HEK293-derived cultures in a reversible manner without affecting cell viability (33 µM for 24 h).
A naturally isolated Ginkgo biloba biflavanoid that acts as a cell-permeable, reversible inhibitor against spliceosome-mediated pre-mRNA splicing (IC50 and ICmax = 30 and 50 µM, respectively, in splicing assays using HeLa nuclear extract) by preventing the prespliceosome A complex from recruiting the U4/U5/U6 tri-snRNP (stable nuclear RNA and its associated proteins) to form B complex. Isoginkgetin treatment is shown to result in growth arrest in HEK293-derived cultures in a reversible manner without affecting cell viability (33 µM for 24 h).

Membrane-permeable compounds that reversibly inhibit a particular step in gene expression are highly useful tools for cell biological and biochemical/structural studies. In comparison with other gene expression steps where multiple small molecule effectors are available, very few compounds have been

Matrix metalloproteinase (MMP)-9 plays a key role in tumor invasion. Inhibitors of MMP-9 were screened from Metasequoia glyptostroboides (Dawn redwood) and one potent inhibitor, isoginkgetin, a biflavonoid, was identified. Noncytotoxic levels of isoginkgetin decreased MMP-9 production profoundly, but up-regulated the

In somatic cells, mitotic transcription of major satellite non-coding RNAs is tightly regulated and essential for heterochromatin formation and the maintenance of genome integrity. We recently demonstrated that major satellite transcripts are expressed, and chromatin-bound during mouse oocyte meiosis. Pericentric
