Abstract:
The cyclinD1 is an emerging potent therapeutic drug target in the treatment of ovarian cancer. CyclinD1, Cdks phosphorylation regulates cell cycle and controls transcription. For this reason, CyclinD1 have been subject to extensive cell cycle- related research, and consequently various therapeutic inhibitor drugs have been developed to these protein targets. In the present study we identified that the expression levels of Bcl-2, Bax, caspase 8, 9 and cyclinD1 using Q-PCR method in SKOV3 cell lines treated with Isochamanetin. The viability and migratory inhibition ability also studied to know the mode of cell death. Further the expression levels of Bcl-2, caspase8,9, Cytochrome C and CyclinD1 were significantly down regulated in SKOV3 cancer cells treated with isochamanetin, a specific binding molecule to CyclinD1. The therapeutic molecules found by a high through put insilicoscreen of this pocket exhibit cytostatic nature and reduce protein levels of cell cycle. The novel structural site on CyclinD1, which is well conserved and inhibits the SKOV3 cells from G0-G1 to S phase cell cycle progression. The current result suggests that isochamanetin serves as potent binding agent to the cyclinD1.

- SKOV3 ovarian cancer cells were treated with Isochamanetin.
- Cell viability and migratory inhibition assays were performed.
- In silico screening was employed to identify therapeutic molecules targeting Cyclin D1.
Main Results:
- Isochamanetin treatment significantly downregulated the expression of Bcl-2, Bax, caspase 8, 9, Cytochrome C, and Cyclin D1 in SKOV3 cells.
- The compound demonstrated cytostatic effects, inhibiting cell viability and migration.
- A novel, conserved structural site on Cyclin D1 was identified, which Isochamanetin binds to.
- Isochamanetin effectively inhibited G0-G1 to S phase cell cycle progression in SKOV3 cells.
Conclusions:
- Isochamanetin acts as a potent binding agent to Cyclin D1.
- The findings suggest Isochamanetin has therapeutic potential in ovarian cancer treatment by targeting Cyclin D1 and disrupting cell cycle progression.
