Induction of RIPK3/MLKL-mediated necroptosis by Erigeron breviscapus injection exhibits potent antitumor effect

Current advances on the therapeutic potential of scutellarin: an updated review

Scutellarin is widely distributed in Scutellaria baicalensis, family Labiatae, and Calendula officinalis, family Asteraceae, and belongs to flavonoids. Scutellarin has a wide range of pharmacological activities, it is widely used in the treatment of cerebral infarction, angina pectoris, cerebral thrombosis, coronary heart disease, and other diseases. It is a natural product with great research and development prospects. In recent years, with in-depth research, researchers have found that wild scutellarin also has good therapeutic effects in anti-tumor, anti-inflammatory, anti-oxidation, anti-virus, treatment of metabolic diseases, and protection of kidney. The cancer treatment involves glioma, breast cancer, lung cancer, renal cancer, colon cancer, and so on. In this paper, the sources, pharmacological effects, in vivo and in vitro models of scutellarin were summarized in recent years, and the current research status and future direction of scutellarin were analyzed.

Current evidence and therapeutic implication of PANoptosis in cancer

Regulated cell death (RCD) is considered a critical pathway in cancer therapy, contributing to eliminating cancer cells and influencing treatment outcomes. The application of RCD in cancer treatment is marked by its potential in targeted therapy and immunotherapy. As a type of RCD, PANoptosis has emerged as a unique form of programmed cell death (PCD) characterized by features of pyroptosis, apoptosis, and necroptosis but cannot be fully explained by any of these pathways alone. It is regulated by a multi-protein complex called the PANoptosome. As a relatively new concept first described in 2019, PANoptosis has been shown to play a role in many diseases, including cancer, infection, and inflammation. This study reviews the application of PCD in cancer, particularly the emergence and implication of PANoptosis in developing therapeutic strategies for cancer. Studies have shown that the characterization of PANoptosis patterns in cancer can predict survival and response to immunotherapy and chemotherapy, highlighting the potential for PANoptosis to be used as a therapeutic target in cancer treatment. It also plays a role in limiting the spread of cancer cells. PANoptosis allows for the elimination of cancer cells by multiple cell death pathways and has the potential to address various challenges in cancer treatment, including drug resistance and immune evasion. Moreover, active investigation of the mechanisms and potential therapeutic agents that can induce PANoptosis in cancer cells is likely to yield effective cancer treatments and improve patient outcomes. Research on PANoptosis is still ongoing, but it is a rapidly evolving field with the potential to lead to new treatments for various diseases, including cancer.

A sport supplement candidate of Erigeron breviscapus extract regulates lipogenesis in vitro and in vivo

PURPOSE

One of the urgent research projects in exercise science should focus on sports supplements for obese people who lack exercise and physical activity. In this study, we explored the efficacy in non-alcoholic fatty liver disease (NAFLD) mice models using a Korean herbal medicine Erigeron breviscapus (EB).

METHODS

Gene ontology analyses of active compounds in EB were performed using the Traditional Chinese Medicine Database and Analysis Platform (TCMSP) and Cytoscape program, respectively. PA-induced acid (PA) induced-lipid droplets in HepG2 cells were analyzed using a 3D-hologram. To analyze the fat-suppressing efficacy of EB in animal experiments, NAFLD was induced through a 24-week high-fat diet. Subsequently, the same diet was continued for an additional 8 weeks, with concurrent co-administration of drugs for efficacy analysis. In the 8-week experiment, mice were administered saline alone, metformin (17 mg/kg/day), or EB (26 mg/kg/day). The mice were sacrificed and the liver tissue was isolated. The liver tissues were stained with H&E and specific antibodies such as sterol regulatory element binding protein 1 (SREBP-1) and peroxisome proliferator-activated receptor- γ (PPAR-γ).

RESULTS

Seventeen EB-active compounds were identified by whole-body analysis. EB downregulated lipid droplets in PA-treated HepG2 cells. EB regulates lipid accumulation in liver tissue of HFD-fed NAFLD mice Metformin and EB significantly reduced the expression of SREBP-1 and PPAR-γ in liver tissue.

CONCLUSION

We suggest that EB is a candidate for the management of NAFLD and is an effective exercise supplement owing to its ability to inhibit lipid accumulation.
