Project description:We observed that luteolin effectively restrained the growth of solid tumors in the established mouse model of HCC. Expression spectrum chip sequencing showed that treatment with luteolin could promote T cell activation, cell chemotaxis and cytokine production. Furthermore, we explored the influence of luteoin on the phenotypic and functional alterations of T cells. Our findings revealed that luteolin maintained a high ratio of CD8+ T cells in the peripheral blood, spleen, and tumor tissues. Additionally, luteolin restored the cytotoxicity of tumor-infiltrating CD8+ T cells in H22 tumor-bearing mice. Moreover, CD8+ T cells showed stronger activation phenotypes and more production of IFN-γ, TNFα, and Granzyme B in serum. Furthermore, the co-administration of luteolin and PD-1 mAb resulted in potentiated anti-tumor effects in H22 tumor-bearing mice.These findings indicate that luteolin could exert an anti-tumor immune response by inducing CD8+ T cell infiltration and enhance the anti-tumor effects of PD-1 mAb in HCC treatment in H22 tumor-bearing mice.

Project description:The aim was to investigate mechanisms contributing to quercetin’s previously described effects on cell-proliferation and -differentiation, which contradicted its proposed anti-carcinogenic potency. In a 10-day experiment, 40 µM quercetin stabilized by 1mM ascorbate reduced Caco-2 differentiation up to 50% (P<0.001). Caco-2 RNA from days 5 and 10, hybridized on HG-U133A2.0 Affymetrix® GeneChips®, showed 1,743 affected genes on both days (P<0.01). All 14 Caco-2 differentiation-associated genes showed decreased expression (P<0.01), including intestinal alkaline phosphatase that was confirmed technically (qRT-PCR) and functionally (enzyme-activity). The 1,743 genes contributed to 27 affected pathways (P<0.05) categorized under 6 gene ontology (GO) processes, including apoptosis and cell-cycle. Genes within these GO-processes showed fold changes that suggest increased cell-survival and -proliferation. Furthermore, quercetin downregulated expression of genes involved in tumor-suppression and phase II metabolism, and upregulated oncogenes. Gene expression changes mediated by ascorbate-stabilized quercetin were concordant with those occurring in human colorectal carcinogenesis (≈ 80-90%), but were opposite to those previously described for Caco-2 cells exposed to quercetin in the absence of ascorbate (≈ 75-90%). In conclusion, gene expression among Caco-2 cells exposed to ascorbate-stabilized quercetin showed mechanisms contrary to what is expected for a cancer-preventive agent. Whether this unexpected in vitro effect is relevant in vivo, remains to be elucidated. Keywords: Colon cancer; Caco-2; quercetin; differentiation

Project description:To determine if any altered miRNA expression is actually involved in the growth inhibition and/or cell death induction by luteolin and/or gefitinib, we performed miR-array analysis using RNA from PC-3 cells after 24h of treatment with 60μM luteolin and/or 60μM gefitinib. PC-3 cells were treated for 24h with DMSO, 60μM luteolin (Lut), 60μM gefitinib (Gef) or their co-administration (Lut+Gef). Each sample was run in duplicate.

Project description:As the critical step of pathogenesis during hypoxic pulmonary arterial hypertension (PAH) vascular remodeling is closely associated with pulmonary arterial smooth muscle cell (PASMC) alterations induced by hypoxia that include persistent vasoconstriction, abnormal proliferation and PASMC resistance to apoptosis. Quercetin is a flavonoid compound extracted from green plants that inhibits proliferation, induces apoptosis, arrests the cell cycle, and rescues the constriction of PASMCs, but the underlying mechanisms remain poorly understood. In this study, we used a commercial Agilent Whole Rat Genome Oligo Microarray to determine the overall transcriptional response of PASMCs in response to exposure to hypoxia and the optimal concentration of quercetin. Hypoxia induced the upregulation of 1694 genes and the downregulation of 2091 genes compared with the normoxia group. Quercetin treatment resulted in 1790 upregulated genes and 1450 downregulated genes. Quercetin is known to cause differential expression of several of these genes that are known to promote proliferation, induce apoptosis (Cycs, Ppp3ca, Prkar2b, Akt3, Ppp3cc, Il1rap, Ntrk1), arrest the cell cycle (Chek2, Cdkn1c, Gadd45b, Stag2, Anapc7, Orc1, Ccne1, Myc3, Skp1, Espl1, Cdc45, Mcm4), and rescue PASMC constriction (Ramp1, Ramp3, Adcy5, Gnas, Prkcd, Itpr3, Adra1d, Calm1, Npr1, Avpr1a, Ednra, Adcy8). Real-time quantitative RT-PCR was performed to verify the microarray results. In conclusion, quercetin altered the expression profile of many genes regulated by hypoxia in PASMCs, which helps to further explore the mechanism of the effects of quercetin treatment on hypoxic PAH.

Project description:Using mice deficient in hepatic cytochrome-P450 oxidoreductase (POR), which disables the liver cytochrome P450 system, the metabolism and biological response of the anti-carcinogenic flavonoid, quercetin, was examined. Profiling circulating metabolites revealed similar profiles over 72 h in wild type (WT) and POR-null (KO) mice, showing that hepatic P450 and reduced biliary secretion do not affect quercetin metabolism. Transcriptional profiling at 24 h revealed that 2-3 fold more genes responded significantly to quercetin in WT compared to KO in the jejunum, ileum, colon, and liver, suggesting that hepatic P450s mediate many of the biological effects of quercetin, such as immune function, estrogen receptor signaling and lipid, glutathione, purine, and amino acid metabolism, even though quercetin metabolism is not modified. The functional interpretation of expression data in response to quercetin (single dose of 7 mg/animal) revealed a molecular relationship between the liver and jejunum. In WT animals, amino acid and sterol metabolism were predominantly modulated in the liver, fatty acid metabolism response was shared between the liver and jejunum, and glutathione metabolism was modulated in the small intestine. In contrast, KO animals do not regulate amino acid metabolism in the liver or small intestine, they share the control of fatty acid metabolism between the liver and jejunum, and regulation of sterol metabolism is shifted from the liver to the jejunum and that of glutathione metabolism from the jejunum to the liver. This demonstrates that the quercetin-mediated regulation of these biological functions in extrahepatic tissues is dependent on the functionality of the liver POR. In conclusion, using a systems biology approach to explore the contribution of hepatic phase I detoxification on quercetin metabolism demonstrated the resiliency and adaptive capacity of a biological organism in dealing with a bioactive nutrient when faced with a tissue-specific molecular dysfunction. Keywords: nutritional intervention, comparative genomic response, genotype variation
