AI Article Synopsis
- Cyanidin shows potential as a treatment for glioma stem cells (GSCs), significantly reducing cell viability across multiple GSC lines, particularly in GBM2.
- The compound regulates the Wnt signaling pathway, affecting the expression of associated genes and reducing levels of β-catenin and c-Myc proteins.
- Overall, cyanidin may combat tumor growth in gliomas by targeting key signaling pathways and protein expressions related to cell survival and proliferation.
Article Abstract
Background: Cyanidin has a protective effect on the nervous system and has been reported to treat tumor effectively. However, its impact on glioma stem cells (GSC) is unknown.
Methods: Using seven GSC lines, the anti-tumor effect of cyanidin is tested. The effect of cyanidin on the cell viability in each cell line is evaluated. Wnt signaling pathway-related genes are checked after treatment of cyanidin. Cytoplasmic/nuclear β-catenin protein levels post cyanidin treatment is detected. Protein levels of c-Myc after cyanidin treatment are determined. Twist1 and Snail1 protein levels after cyanidin treatment are checked as well.
Results: Cyanidin significantly reduces the cell viability of all GSCs, and exhibited the most substantial effect in GBM2 but no apparent effect in 293T cells. It can regulate the Wnt signaling pathway of all GSC lines. In the GBM2, GBM7, G166, and G179 cell lines, there is upregulation of and genes, while in the G144 and GliNS2 cell line, these two genes are down-regulated after cyanidin treatment. Cytoplasmic and nuclear protein levels of β-catenin in all cell lines are down-regulated. Cyanidin treatment significantly decreases the protein level for c-Myc in the GBM2 cell line compared with untreated cells, not in G144 or GliNS2 cells. Furthermore, cyanidin strongly reduces the expression of Twist1 and Snail1 in GBM2, G179, and G144 cell lines, while the GliNS2 cells show an opposite change in the cytoplasm and no change in nuclear.
Conclusion: Cyanidin exerts an anti-tumor effect in glioma stem cell lines, probably through the Wnt signaling pathway.

The health benefits of mulberry fruit are closely associated with its phenolic compounds. However, the effects of enzymatic treatments on the digestion patterns of these compounds in mulberry juice remain largely unknown. This study investigated the impact of pectinase (PE), pectin lyase (PL), and cellulase (CE) on the release of phenolic compounds in whole mulberry juice.

High temperature stress leads to a dramatic reduction of both the anthocyanin concentration and the appearance quality of colored potatoes. However, it remains uncertain if the high temperature impacts potato tuber skin coloring through only the aerial or belowground parts of the plant, or through their interaction; and it's underlying reason is still unclear. In this study, the red-skin cultivar Qingshu9 (Qs9) was exposed to the high-temperature (30 °C) treatment on the belowground part alone (BH), aerial part alone (AH) and entire plant (EH), and the normal-temperature treatment on entire plant (EN) as control.

Obesity-related glomerulopathy (ORG) represents an escalating public health with no effective treatments currently available. Abnormal lipid metabolism and lipid droplet deposition in the kidneys are key contributors to ORG. Cyanidin-3-glucoside (C3G) has shown potential in regulating lipid metabolism and may offer reno-protective effects; however, its therapeutic efficacy and underlying mechanisms in ORG remain unclear.
