Unravelling the antitumor mechanism of Ocoxin through cancer cell genomics

Area of Science:

• Oncology
• Molecular Biology
• Pharmacology

Background:

• Cancer remains a leading global cause of death, with existing therapies often limited by efficacy and severe side effects impacting patient quality of life.
• Ocoxin, a complex mixture of plant extracts, amino acids, vitamins, and minerals, possesses known antioxidant, anti-inflammatory, and immunoregulatory properties.
• Preclinical studies suggest Ocoxin exhibits antitumor effects across various cancer types.

Purpose of the Study:

• To elucidate the specific mechanisms of action of Ocoxin in four distinct cancer models: colorectal cancer, triple-negative breast cancer, pancreatic cancer, and prostate cancer.
• To identify common and cancer-specific molecular pathways modulated by Ocoxin.
• To evaluate the potential of Ocoxin as an adjunctive therapeutic agent.

Main Methods:

• RNA sequencing was employed to analyze gene expression changes induced by Ocoxin in the selected cancer models.
• Bioinformatic analyses were performed to identify key biological pathways affected by Ocoxin treatment.
• Comparative analysis across different cancer types was conducted to find common molecular targets.

Main Results:

• Ocoxin primarily alters cancer cell metabolism, notably inducing ferroptosis, a regulated form of cell death.
• Significant modulation of the cell cycle was observed, indicating interference with cancer cell proliferation.
• Ocoxin affected 13 common genes across all four cancer types, implicating metabolism, cell cycle, integrated stress response, and unfolded protein response pathways in its mechanism of action.

Conclusions:

• Ocoxin induces cancer cell death through multiple pathways, including ferroptosis, cell cycle modulation, integrated stress response, and unfolded protein response.
• While specific mechanisms vary by cancer type, Ocoxin demonstrates potential as a complementary treatment to enhance current cancer therapies.
• The findings support Ocoxin's potential role in improving therapeutic outcomes for patients with colorectal, breast, pancreatic, and prostate cancers.
