The molecular effects of Saussurea lappa extracts, a traditional medicine in Eastern Asia, on the fate of gastric carcinoma have not been understood. In this study, its cytostatic effects were examined using gastric AGS cancer cells. Its treatment resulted in apoptosis and G2-arrest in a dose- and time-dependent manner. The effects were attributed to the regulation of cyclins and pro-apoptotic molecules and suppression of anti-apoptotic molecules. Therefore, these results suggest that extracts of S. lappa root may be a candidate to deal with gastric cancers either by traditional herbal therapy or by combinational therapy with conventional chemotherapy.

Saussurea medusa is a rare alpine plant with significant medicinal value. To better understand the changes in its habitat in the context of climate change, this study used an optimized MaxEnt model to predict the current and future habitat of S. medusa under four shared socioeconomic pathways (SSPs) across three time periods (current, mid-century, and end-century) based on three climate system models.

Photosynthesis is essential for the accumulation of organic compounds in plant leaves. Study of photosynthesis in the leaves of Broussonetia papyrifera is crucial for enhancing its biomass production, growth, and development. Here, we cloned the SikPsaF gene associated with photosynthesis from Saussurea involucrata and constructed a vector that was introduced into B.

Sesquiterpene lactones (SLs) are a class of natural products with diverse structural scaffoldings and biological activities, making them intriguing objects in the fields of pharmaceutical industry, drug development, and pharmacology. Herein, fifteen SLs, including eleven undescribed SLs compounds sauruintones A-K (1-8 and 13-15), were isolated and identified from the aerial parts of Saussurea involucrata. Their structures were characterized by using mass spectrometry, spectroscopic methods, computational calculations, and single crystal X-ray diffraction.
