The fused cells were established using envelopes of a hemagglutinating virus of Japan, which increased cell proliferation, motility, and drug resistance. Comprehensive gene expression profile analysis revealed that the fused cells expressed higher levels of glycolysis-related genes than their parental cells. In fact, the fused cells relied more on glycolysis for ATP production (Warburg effect). <em>HIF1A</em>, which induces the expression of glycolysis-related genes, was upregulated in fused cells compared to MCF-7 cells. Allele-specific expression analysis of the fused cells indicated that MSC allele-derived HIF1A efficiently induces the expression of glycolysis-related genes in the MCF-7 allele.

Conventional antidepressants are often limited by delayed therapeutic effects and notable adverse reactions, necessitating the development of innovative and efficacious treatment modalities. Multiple lines of evidence suggest that peripheral and central inflammation play a role in depression, and that anti-inflammatory drugs can ameliorate depressive symptoms in patients with inflammation-related depression. Pinocembrin (PB), a natural bioactive compound, is renowned for its anti-inflammatory and antioxidant properties, while the effect and mechanism of PB are still unclear.

In this study, the critical targets and potential mechanisms of Cur in treating vitiligo were predicted by network pharmacology and molecule docking. Then, the effects of Cur on Erastin-induced ferroptosis were investigated in melanocytes induced by Erastin in vitro. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of Cur acting on Vitiligo found that these intersection genes are associated with the vitiligo oxidative stress pathway, including nuclear factor erythroid 2-related factor 2(Nrf2)/Heme Oxygenase 1(HO-1) signaling pathway.
