Insights

Phellinus igniarius extract shows potent antitumor effects against gastric cancer cells. It induces apoptosis through a mitochondria-dependent pathway, offering potential as a natural therapeutic agent.

Area of Science:

  • Oncology
  • Pharmacology
  • Natural Products Research

Background:

  • Gastric cancer (GC) is a leading cause of cancer death globally.
  • Phellinus igniarius is a traditional East Asian medicinal mushroom with reported anti-cancer properties.

Purpose of the Study:

  • To evaluate the anti-tumor activity of Phellinus igniarius extract.
  • To elucidate the underlying mechanisms of its anti-cancer effects.

Main Methods:

  • MTT assay for in vitro cytotoxicity.
  • Xenograft nude mouse model for in vivo tumor growth inhibition.
  • Flow cytometry and Western blotting to analyze apoptosis and cell cycle.

Main Results:

  • Total ethanol extract of Phellinus igniarius (TPI) exhibited cytotoxicity against multiple cancer cell lines, notably gastric cancer SGC-7901.
  • TPI significantly inhibited tumor growth in vivo and induced apoptosis in SGC-7901 cells.
  • TPI triggered mitochondrial-dependent apoptosis by down-regulating cyclin D1, collapsing mitochondrial membrane potential, activating caspases, and altering Bax/Bcl-2 ratio.

Conclusions:

  • Phellinus igniarius extract demonstrates significant anti-tumor activity against gastric cancer.
  • The extract induces apoptosis via a mitochondria-dependent pathway, suggesting its potential as a natural therapeutic agent for gastric cancer prevention and treatment.

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Peroxisomes and Mitochondria

Peroxisomes and mitochondria are two important oxygen-utilizing organelles in eukaryotic cells. Mitochondria carry out cellular respiration—the process that converts energy from food into ATP. Peroxisomes carry out a variety of functions, primarily breaking down different substances, such as fatty acids.
The peroxisome is a single membrane-bound cellular organelle that can perform several different functions, including lipid metabolism and chemical detoxification. The enzymes within...

Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
