Harnessing nature's arsenal: Targeting the TGF-β/Smad Cascade with novel natural anti-fibrotic agents.

Background: Hepatic fibrosis is a wound healing response that leads to excessive deposition of extracellular matrix (ECM) due to sustained liver injury. Hepatic stellate cells (HSCs) are key players in ECM synthesis, with the TGF-β/Smad signaling pathway being central to their activation. Despite advances in understanding the pathogenesis of hepatic fibrosis, effective anti-fibrotic therapies are still lacking.

Methods: This treatise conducts a comprehensive review of the literature on the hepatoprotective effects of natural products, including natural medicine compounds, herbal extracts, and polysaccharides. The focus is on their ability to modulate the TGF-β pathway, which is critical in the activation of HSCs and ECM synthesis in hepatic fibrosis.

Results: The review identifies a variety of natural products that have shown promise in inhibiting the TGF-β/Smad signaling cascade, thereby reducing the activation of HSCs and ECM accumulation. These findings highlight the potential of these natural products as therapeutic agents in the treatment of hepatic fibrosis.

Conclusions: The exploration of natural products as modulators of the TGF-β pathway presents a novel avenue for both clinical and preclinical research into hepatic fibrosis. Further investigation is warranted to fully understand the mechanisms of action and to develop these compounds into effective anti-fibrotic pharmaceuticals.
