A Animal Study published in 2024 in the journal International Journal of Biological Macromolecules found that A polysaccharide from Tremella aurantialba improves ulcerative colitis symptoms by targeting epithelial cell ferroptosis and modulating the gut microbiota. The methodology used in this research involved isolating TA 2-1, a specific polysaccharide from Tremella Aurantialba, and studying its effects on ulcerative colitis. This was done by introducing it to Caco-2 cells that were undergoing ferroptosis and assessing its impact on cell viability. The influence of TA 2-1 was also examined in mice with artificially induced ulcerative colitis, verifying its ameliorating effects in an in-vivo context. The structure of TA 2-1 and its components were analysed and the polysaccharide's interaction with gut microbiota was explored to understand how it might modulate symptoms or prevent cell death. The results of this study showed that TA 2-1 does not only decrease the rate of cell death in epithelial cells undergoing ferroptosis, but it also repairs the intestinal barrier by upregulating specific proteins such as claudin-1 and zonula occludens-1. TA 2-1 was also found to suppress lipid peroxidation, thus inhibiting ferroptosis. Further investigation revealed that TA 2-1 may alleviate ulcerative colitis by influencing the composition or metabolites of gut microbiota. This research offers promising insight into the potential of TA 2-1 in treating ulcerative colitis.

A Experimental Study published in 2023 in the journal Heliyon found that Qi Shen Tang, a traditional Chinese medicine, was found to suppress retinal cell death in retinitis pigmentosa by inhibiting a process called ferroptosis. The researchers investigated the potential mechanism of Qi-Shen-Tang (QST), a combination of two traditional Chinese medicines, on retinitis pigmentosa, an eye disease. They induced a retinitis pigmentosa model in mice while subsequently treating them with QST. They then examined the impact of the medicine on the tissue morphology and function of the retina in these model mice, in addition to monitoring factors such as retinal blood flow and fundus structure. The study found that the treatment with QST led to notable improvements in the retinal tissue morphology and function. In addition, they observed an increase in retinal blood flow and normalization of the fundus structure. Following the treatment, the amounts of iron and malondialdehyde in the retinal tissue were significantly reduced, while the levels of superoxide dismutase, glutathione, and the protein expressions of various enzymes significantly increased. Molecular docking results also revealed potential interactions between the components of QST and key proteins of a particular signaling pathway, namely the Nuclear factor erythroid 2-related factor 2/ Glutathione peroxidase 4 pathway. The results suggest that QST may inhibit ferroptosis by suppressing this signaling pathway, thereby mitigating retinitis pigmentosa-induced damage to the retinal tissue.

A Experimental Study published in 2023 in the journal Biomedicine & Pharmacotherapy found that Fructus Lycii and Salvia miltiorrhiza Bunge extract (FSE) shows potential as a clinical treatment for retinitis pigmentosa by inhibiting photoreceptor cell death following oxidative stress. The study utilized hydrogen peroxide to induce oxidative stress in 661 W cells, which were examined with flow cytometry and an enzyme-linked immunosorbent assay. The impact of this oxidative stress on the cells’ mitochondria was observed using an electron microscope to understand the nature of cell death. The study also analyzed the compensatory effect of the Fructus Lycii and Salvia miltiorrhiza Bunge extract on the retinal structure and function of rd10 mice using histopathological examination, fundus photographs, and electroretinography. Protein levels were evaluated using Western blot assays, specifically targeting proteins including Tumor Protein p53, Solute Carrier Family 7 Member 11, Glutathione peroxidase 4, Arachidonate-12-Lipoxygenase, and Dipeptidyl peptidase 4. The results showed that hydrogen peroxide-induced oxidative stress in 661 W cells increased oxidative stress products and certain protein expressions, while decreasing others. Notably, the activation of Glutathione peroxidase 4 did not lessen reactive oxygen species generation and had little impact on cell death. The research discovered that both Ferrostatin-1 and the extract could lessen reactive oxygen species generation and inhibit cell death of photoreceptors in retinitis pigmentosa, achieving this by inhibiting the expression of one protein and increasing the expression of two others.
