“…Located in southwest China, Yunnan Province benefits from a warm climate with notable diurnal temperature fluctuations, presenting distinctive conditions conducive to the cultivation of natural plants. Numerous bioactive compounds found in these plants have demonstrated antioxidant, hypoglycemic, anti-tumor, and anti-inflammatory properties [49][50][51][52]. Plant polysaccharides, as active ingredients extracted from these plants, have garnered research interest due to their non-toxic nature and affordability.…”

Objective: This study aimed to investigate methodologies for the extraction and purification of polysaccharides from Rosa roxburghii Tratt fruits and their impact on various cellular processes in prostate cancer DU145 cells, including survival rate, migration, invasion, cell cycle, and apoptosis. Results: Compared to the control group, the polysaccharide exhibited a significant reduction in the viability, migration, and invasion rates of DU145 cells in a time- and dose-dependent manner within the polysaccharide-treated groups. Additionally, it effectively arrested the cell cycle of DU145 cells at the G0/G1 phase by downregulating the expressions of CDK-4, CDK-6, and Cyclin D1. Furthermore, it induced apoptosis by upregulating the expressions of Caspase 3, Caspase 8, Caspase 9, and BAX. Methods: Polysaccharides were extracted from Rosa roxburghii Tratt sourced from Yunnan, China. Extraction and decolorization methods were optimized using response surface methodology, based on a single-factor experiment. Polysaccharide purification was carried out using DEAE-52 cellulose and Sephadex G-100 column chromatography. The optimal dosage of R. roxburghii Tratt polysaccharide affecting DU145 cells was determined using the CCK-8 assay. Cell migration and invasion were assessed using transwell and scratch assays. Flow cytometry was employed to analyze the effects on the cell cycle and apoptosis. Western blotting and Quantitative real-time PCR were utilized to examine protein and mRNA expressions in DU145 cells, respectively. Conclusions: Rosa roxburghii Tratt polysaccharides, consisting of D-mannose, L-rhamnose, N-acetyl-D-glucosamine, D-galacturonic acid, D-glucose, D-galactcose, D-xylose, L-arabinose, and L-fucose, possess the ability to hinder DU145 cell proliferation, migration, and invasion while inducing apoptosis through the modulation of relevant protein and gene expressions.

Sulfated polysaccharides SpvF1, SpvF2, SpvF3, and SpvF4 from the brown alga S. vietnamense collected north of Hon Do (Nha Trang Bay, Vietnam) were isolated and studied. The structure of the obtained polysaccharide was studied using chemical methods and NMR spectroscopy. Fucoidans were low-sulfated (SpvF1, SpvF2) and medium-sulfated (SpvF3, SpvF4) heterogeneous polysaccharides. The molecular weight of the polysaccharides obtained was in the range of 16 to 44 kDa. All investigated fucoidans until 400 µg/mL were not cytotoxic for human colon carcinoma cells DLD-1, HCT-116, and HT-29 in vitro. Fucoidans SpvF1 and SpvF2 have inhibited the colony formation and growth of investigated cells from 20 to 30%. Fucoidans SpvF3 and SpvF4 have the strongest inhibitory effect for investigated cancer cells: from 40 to 50%.
