Summary
Ganoderiol F, isolated from Ganoderma leucocontextum, effectively inhibits breast cancer cell growth by inducing cell cycle arrest and apoptosis. This compound shows potential as a CDK4/CDK6 inhibitor for cancer therapy.
Area of Science:
- Natural Product Chemistry
- Molecular Biology
- Cancer Research
Background:
- Ganoderma leucocontextum is a mushroom with potential medicinal properties.
- Identifying novel anti-cancer compounds is crucial for therapeutic development.
Purpose of the Study:
- To isolate and characterize anti-cancer compounds from Ganoderma leucocontextum.
- To investigate the mechanism of action of the isolated compound on breast cancer cells.
Main Methods:
- Bio-activity-guided purification and chromatography.
- In vitro assays on human breast cancer cells (MDA-MB-231).
- In vivo tumor growth inhibition studies in mice (4T1 cells).
Main Results:
- Ganoderiol F was isolated and identified from Ganoderma leucocontextum.
- Ganoderiol F induced apoptosis and G1 phase cell cycle arrest in breast cancer cells.
- Ganoderiol F inhibited tumor growth in vivo and down-regulated key cell cycle regulators (cyclin D, CDK4, CDK6, cyclin E, CDK2) and apoptosis-related proteins (c-Myc, Bcl-2, Bcl-w).
Conclusions:
- Ganoderiol F exhibits significant anti-cancer activity against breast cancer cells.
- Ganoderiol F acts by disrupting cell cycle progression and promoting apoptosis.
- Ganoderiol F is a potential therapeutic agent and CDK4/CDK6 inhibitor for breast cancer treatment.

02:34Inhibition of Cdk Activity
5.6K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

01:23Negative Regulator Molecules
38.3K
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

02:39Positive Regulator Molecules
6.5K
Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.

To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.

01:27Molecular Factors Affecting Cell Division
3.9K
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.

01:28The Cell Cycle Control System
5.4K
The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.
