Insights

Apigenin, a plant flavonoid, inhibits hepatoma cell growth by altering gene expression. This study shows apigenin reduces proliferation, induces apoptosis, and arrests the cell cycle, offering potential anti-cancer strategies.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Apigenin is a flavonoid with known anti-tumor properties.
  • The molecular mechanisms of apigenin's anti-cancer effects are not fully understood.

Purpose of the Study:

  • To investigate apigenin's effects on human hepatoma Huh7 cell proliferation, cell cycle, apoptosis, and tumorigenicity.
  • To elucidate the molecular mechanisms underlying apigenin's anti-cancer activity through gene expression profiling.

Main Methods:

  • In vitro studies on Huh7 cell proliferation, cell cycle, apoptosis, and colony formation.
  • In vivo studies using xenografts to assess tumorigenicity.
  • Genome-wide expression profiling using cDNA microarrays.
  • Quantitative RT-PCR and Western blot analyses for gene validation.

Main Results:

  • Apigenin significantly inhibited Huh7 cell proliferation and colony formation in a dose-dependent manner.
  • Apigenin induced G2/M cell cycle arrest and increased apoptosis in Huh7 cells.
  • Apigenin treatment significantly retarded xenograft tumor growth in vivo.
  • Gene expression profiling revealed significant up-regulation and down-regulation of numerous genes, including IL-4 receptor, USP18, SLC27A3, and CCR2.

Conclusions:

  • Apigenin exhibits significant inhibitory effects on hepatoma cell growth both in vitro and in vivo.
  • The anti-cancer activity of apigenin is likely mediated by alterations in global gene expression profiles.
  • Apigenin represents a promising therapeutic agent for hepatocellular carcinoma.

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...

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...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
