Abstract

Insights

Amentoflavone (AF) effectively suppresses ovarian cancer cell growth and promotes apoptosis. This natural compound works by downregulating Skp2 expression via the ROS/AMPK/mTOR pathway, showing therapeutic potential for ovarian cancer treatment.

Area of Science:

  • Oncology
  • Pharmacology
  • Molecular Biology

Background:

  • Ovarian cancer is a leading cause of cancer-related deaths in women, characterized by high recurrence rates and poor prognosis.
  • Amentoflavone (AF), a natural compound from S. tamariscina, is investigated for its anti-cancer properties.

Purpose of the Study:

  • To investigate the anti-tumor effects of amentoflavone (AF) against human ovarian cancer cell lines.
  • To elucidate the underlying molecular mechanisms of AF's anti-cancer activity.

Main Methods:

  • Utilized human ovarian cancer cell lines (SKOV3, OVCAR-3) and a xenograft mouse model.
  • Assessed cell viability (CCK-8), apoptosis and cell cycle (flow cytometry), ROS generation, and protein expression (Western blot).

Main Results:

  • AF significantly inhibited ovarian cancer cell proliferation, induced apoptosis, and caused cell cycle arrest.
  • AF downregulated S-phase kinase protein 2 (Skp2) expression, a key mechanism for its anti-tumor effect.
  • AF repressed Skp2 expression through the ROS/AMPK/mTOR signaling pathway, confirmed in vivo.

Conclusions:

  • Amentoflavone (AF) demonstrates significant potential as a therapeutic agent for ovarian cancer.
  • The study elucidates AF's anti-tumor mechanisms involving Skp2 downregulation via ROS/AMPK/mTOR signaling.

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

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...

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
