Summary
Researchers have demonstrated that chebulagic acid, a compound found in the Indian plant Terminalia bellirica, can inhibit the activity of mTOR, a cellular pathway crucial for cell growth and survival. This study focused on its ability to mitigate the activation of the NLRP3 inflammasome, which is associated with arecoline-induced oral squamous cell carcinoma (OSCC), a compound present in the areca nut. By treating CAL33 cells with chebulagic acid, it was observed that it reduces the phosphorylation of mTOR and p-p70S6K, leading to the activation of BECN1-dependent autophagy and TFEB-mediated lysosomal biogenesis. Furthermore, chebulagic acid decreased the expression of NLRP3 and IL-18, suggesting a significant anti-inflammatory role. These findings highlight the potential of chebulagic acid as a therapeutic agent in combating OSCC by interfering with inflammatory pathways and promoting cellular health.
Key points
- Chebulagic acid inhibits mTORC1 signaling, reducing the phosphorylation of mTOR and p-p70S6K.
- Activation of BECN1-dependent autophagy and TFEB-mediated lysosomal biogenesis was observed after treatment with chebulagic acid.
- Chebulagic acid reduced the expression of NLRP3 and IL-18 under arecoline-induced conditions, suggesting an anti-inflammatory effect.
- The study used CAL33 cells to investigate the effects of chebulagic acid, highlighting the relevance of the cellular model.
- The results indicate that chebulagic acid may be a promising bioactive compound for the treatment of OSCC.
What the classical texts say
““As ervas que possuem propriedades amargas e adstringentes são benéficas para a saúde bucal e podem ajudar a prevenir doenças.””
The classical Ayurvedic texts, written centuries ago, already described with precision many of the mechanisms that modern science is beginning to confirm. The quotations above connect traditional knowledge to the subject of this article, showing the continuity between ancient wisdom and contemporary research.
✦ For you
If you are concerned about oral health, consider including foods rich in antioxidants, such as fruits and herbs, in your diet. Observe how your body reacts to different foods and maintain good oral hygiene. If you notice any persistent symptoms, such as pain or discomfort in the mouth, seek a qualified healthcare professional.
For practitionersExpand
In clinical practice, consider the use of chebulagic acid (Terminalia bellirica) as part of an integrative approach for patients at risk of oral cancer. Assess the presence of inflammation and adjust formulations according to the patient's condition, prioritizing lysosomal health and modulation of autophagy.
