Taurine Alleviates Dysfunction Of Cholesterol Metabolism Under Hyperuricemia By Inhibiting A2AR-SREBP-2/CREB/HMGCR axis
- Hyperuricemia (HUA) — high uric acid levels — is linked to high cholesterol and increased cardiovascular disease risk.
- Patients with HUA often also have dysfunctional cholesterol metabolism.
- Traditional treatments (like allopurinol) lower uric acid but don’t fix cholesterol problems, suggesting other factors are involved.
Key Findings:
- Adenosine and inosine, two purine metabolites elevated in HUA, increase cholesterol synthesis by activating the A2A adenosine receptor (A2AR).
- This activation triggers the SREBP-2/CREB/HMGCR pathway, leading to higher cholesterol production.
- Taurine levels are low in hyperuricemic patients and mice.
- Supplementing taurine:
- Reduces activation of A2AR.
- Lowers cholesterol levels.
- Decreases uric acid and purine metabolites like inosine and hypoxanthine.
- Reduces activation of A2AR.
- Mechanistically, taurine binds directly to A2AR and inhibits its activity, disrupting the harmful cholesterol-increasing pathway.
Conclusion:
- Purine metabolites (especially adenosine and inosine) — not just uric acid — cause cholesterol metabolism dysfunction in hyperuricemia.
- Taurine is a promising natural treatment to correct cholesterol issues in hyperuricemia by inhibiting the A2AR-SREBP-2/CREB/HMGCR axis.
- This could lower cardiovascular disease risk for people with hyperuricemia.
Impact:
This study opens a new therapeutic approach for managing hyperuricemia and hypercholesterolemia, suggesting taurine supplementation as a simple, safe strategy.

Serum Taurine Affects Lung Cancer Progression By Regulating Tumor Immune Escape Mediated By The Immune Microenvironment
- Taurine, a natural amino acid, has been found at high levels in lung cancer patients.
- Its exact role in lung cancer development and progression was unclear.
Key Findings:
- Taurine has a dual role in lung cancer:
- Low doses (25–50 mg/kg) promoted lung tumor growth in immune-competent mice.
- High doses (200–400 mg/kg) inhibited tumor growth.
- Low doses (25–50 mg/kg) promoted lung tumor growth in immune-competent mice.
- The effects depend heavily on immune competence:
- In immune-competent mice (normal immune system), low taurine increased oxidative stress (ROS) and promoted immune escape via the Nfe2l1-ROS-PD-1 axis.
- In immune-deficient mice (lacking T cells), taurine inhibited tumor growth by suppressing NF-κB-mediated inflammation.
- In immune-competent mice (normal immune system), low taurine increased oxidative stress (ROS) and promoted immune escape via the Nfe2l1-ROS-PD-1 axis.
Mechanisms Identified:
- Nfe2l1 (a transcription factor) was key:
- Low taurine downregulated Nfe2l1, leading to tumor progression.
- High taurine upregulated Nfe2l1, boosting anti-tumor immune responses.
- Low taurine downregulated Nfe2l1, leading to tumor progression.
- Taurine’s effects were reversed by bile acids (like cholic acid), suggesting they could neutralize taurine in therapy.
- As lung cancer patients age, Nfe2l1 expression naturally declines, diminishing its anti-cancer effects.
Conclusions:
- Taurine could act as a biomarker for lung cancer progression.
- Younger patients (with stronger immune systems) should be cautious about consuming taurine or taurine-containing energy drinks.
- Older or immune-deficient patients might benefit from taurine.
- Taurine’s effects depend on the dose, immune status, and patient age.
Impact:
This is the first study to directly show that taurine at low doses can promote lung cancer in immunocompetent hosts. It provides new insights into using taurine carefully in cancer treatment strategies.
