Coenzyme Q (CoQ), a quinone derivative from , has antitumor capabilities. This study investigated the antitumor effect of noncytotoxic CoQ, which included NLRP3 inflammasome inhibition, anti-EMT/metastasis, and metabolic reprogramming via HIF-1α inhibition, in HNSCC cells under normoxia and hypoxia. CoQ suppressed hypoxia-induced ROS-mediated HIF-1α expression in OECM-1 and SAS cells.

Background: Antrodia salmonea (AS) exhibits anticancer activities against various cancers.
Objective: This study investigated the anticancer activities of AS on human glioblastoma (GBM8401 and U87MG) cells both in vitro and in vivo and explained the underlying molecular mechanism.
Methods: MTT, colony formation, migration/invasion assay, immunoblotting, immunofluorescence, TUNEL, Annexin V/PI staining, AO staining, GFP-LC3 transfection, TEM, qPCR, siLC3, DCFH2-DA assay, and xenografted-nude mice were used to assess the potential of AS therapy.
Coenzyme Q (CoQ) analogs with a variable number of isoprenoid units have exhibited as anti-inflammatory as well as antioxidant molecules. Using novel quinone derivative CoQ (2,3-dimethoxy-5-methyl-1,4-benzoquinone, zero side chain isoprenoid), we studied its molecular activities against LPS/ATP-induced inflammation and redox imbalance in murine RAW264.7 macrophages.

Glioblastoma multiforme is a common tumor affecting the central nervous system. This study explored anticancer properties of CoQ on human glioblastoma both in vitro and in vivo, and explained the molecular mechanism behind it.

In this study, we studied the anticancer efficacies of AS (0-240 μg/ml) by examining the key molecular events implicated in cell death associated with autophagy in SKOV-3 and A2780 human ovarian carcinoma cells and clarified the fundamental molecular mechanisms. Treatment of ovarian carcinoma cells with AS-induced autophagic cell death mediated by increased microtubule-associated protein LC3-II, GFP-LC3 puncta, and acidic vesicular organelle (AVO) formation.

Chalcones are reportedly cancer chemo-preventive food components that are rich in fruits and vegetables. In this study, flavokawain A (FKA, 2-30 μM), a naturally occurring chalcone in kava extracts, was evaluated for its anti-fibrotic and antioxidant properties in TGF-β1-stimulated vascular smooth muscle (A7r5) cells, as well as its underlying molecular mechanism of action.

View Article and Find Full Text PDFAntrodia salmonea (AS), a well-known medicinal mushroom in Taiwan, has been reported to exhibit anti-oxidant, anti-angiogenic, anti-atherogenic, and anti-inflammatory effects. In the present study, we investigated the activation of Nrf2-mediated antioxidant genes in RAW264.7 macrophages by the fermented culture broth of AS, studied the resulting protection against lipopolysaccharide (LPS)-stimulated inflammation, and revealed the molecular mechanisms underlying these protective effects.

Materials And Methods: In the present study, we examined the anti-tumor activity of the fermented culture broth of Antrodia salmonea (AS) in vitro and in vivo and revealed its underlying molecular mechanism of action.
Results: Treatment of human promyelocytic leukemia (HL-60) cells with AS (50-150 μg/mL) significantly reduced cell viability and caused G1 arrest via the inhibition of cell-cycle regulatory proteins, including cyclin D1, CDK4, cyclin E, cyclin A, and phosphorylated retinoblastoma protein (p-Rb).
Antrodia salmonea is well known in Taiwan as a beneficial mushroom. In the present study, we investigated the antioxidant activity of whole fermented broth (AS), filtrate (ASF), and mycelia (ASM) of A. salmonea using different antioxidant models.

However, whether AC is effective against HER-2/neu-overexpressing breast cancers has not been thoroughly elucidated. In the present study, we showed that AC exhibited a significant cytotoxic effect against HER-2/neu-overexpressing MDA-MB-453 and BT-474 cells.
