Korean Red Ginseng Extract Increases Apoptosis by Activation of the Noxa Pathway in Colorectal Cancer

Area of Science:

• Oncology
• Pharmacology
• Cell Biology

Background:

• The anticancer properties of Korean Red Ginseng (KRG) are documented across several cancer types.
• The specific mechanisms underlying KRG-induced apoptosis in colorectal cancer (CRC) remain largely uncharacterized.

Purpose of the Study:

• This study aimed to investigate whether KRG can induce apoptosis in colorectal cancer (CRC) cells.
• To elucidate the molecular pathways involved in KRG's effect on CRC.

Main Methods:

• Cell viability assays were performed on multiple CRC cell lines.
• KRG extracts were used at a fixed concentration of 2.5 mg/mL.
• Apoptosis induction by KRG in CRC cells was confirmed through various experimental assays.

Main Results:

• KRG treatment led to the activation of Noxa, a key protein in apoptosis.
• Increased endoplasmic reticulum stress was observed, mediated by reactive oxygen species (ROS) production.
• KRG demonstrated efficient enhancement of cell death in CRC cells.

Conclusions:

• The findings indicate that KRG effectively induces apoptosis and endoplasmic reticulum stress in CRC cells.
• KRG shows promise as a potential therapeutic agent for colorectal cancer.
