Abstract
Lipid metabolism disorder is the most critical risk factor for atherosclerosis, and the process involves lipid deposition in the arterial intima. In Taiwan, antcin K, an active triterpenoid from the fruiting bodies of Antrodia camphorata, has been considered a potential lipid-lowering agent. Despite this, the possible therapeutic mechanisms of antcin K remain unclear. To explore the crucial role of botanical antcin K in reducing atherosclerotic plaque, we used SVEC4-10 vascular endothelial cells and RAW264.7 macrophages with palm acid oil-induced high-fat damage as our cell models. Our results showed through using the DPPH assay that antcin K had excellent free radical scavenging ability. Antcin K treatment can significantly alleviate the high-fat damage and reduce the levels of inflammatory factors of TNF-α and IL-1β in vascular endothelial cells and macrophages, as shown through MTT assay and ELISA. Furthermore, antcin K treatment can effectively enhance migration ability and clear lipid deposition in macrophages, as shown by using cell migration assay and oil red O staining. When stained with immunofluorescence, antcin K was shown to significantly decrease the expression of adhesion molecules of vascular cell adhesion molecule 1 (VCAM-1) in vascular endothelial cells involved in monocyte migration and inflammation. Antcin K not only reduced the expression of the CD36 scavenger receptor but also augmented the expression of Kruppel-like factor 4 (KLF4) transcription factor in macrophages, which inhibits the transformation of macrophages into foam cells underlying the pathological process of atherosclerosis. Taking our findings into account, we suggested that botanical antcin K could have therapeutic potential for the treatment of atherosclerosis.

Abstract
Extracts from Taiwan’s traditional medicinal mushroom, Antrodia cinnamomea, exhibit anti-inflammatory activities in cellular and preclinical studies. However, this paper is the first to report that Antcin K, a triterpenoid isolated from A. cinnamomea, inhibits proinflammatory cytokine production in human rheumatoid synovial fibroblasts (RASFs), which are major players in rheumatoid arthritis (RA) disease. In our analysis of the mechanism of action, Antcin K inhibited the expression of three cytokines (tumor necrosis factor alpha [TNF-α], interleukin 1 beta [IL-1β] and IL-8) in human RASFs; cytokines that are crucial to RA synovial inflammation. Notably, incubation of RASFs with Antcin K reduced the phosphorylation of the focal adhesion kinase (FAK), phosphoinositide 3-kinase (PI3K), protein kinase B (AKT) and nuclear factor-κB (NF-κB) signaling cascades, all of which promote cytokine production in RA. Intraperitoneal injections of Antcin K (10 mg/kg or 30 mg/kg) attenuated paw swelling, cartilage degradation and bone erosion, and decreased serum levels of TNF-α, IL-1β, IL-8 in collagen-induced arthritis (CIA) mice; in further experiments, IL-6 levels were similarly reduced. The inhibitory effects of Antcin K upon TNF-α, IL-1β and IL-8 expression in human RASFs was achieved through the downregulation of the FAK, PI3K, AKT and NF-κB signaling cascades. Our data support clinical investigations using Antcin K in RA disease.

Abstract
Antrodia cinnamomea (AC), an edible Taiwanese mushroom, has been recognized as a valuable natural resource with vast biological and medicinal benefits. Recently, the hypoglycemic and anti-diabetic effects of AC were mentioned in several studies. However, no studies have investigated α-glucosidase inhibitors from AC fruiting bodies (ACFB) as they relate to type 2 diabetes (T2D) treatment. The purpose of this study was to gain evidence of potent α-glucosidase inhibitory effects, as well as isolate, identify and characterize the active compounds of ACFB. The MeOH extract of ACFB demonstrated potent α-glucosidase inhibitory activity, and possessed high pH stability (pH 2⁻11) and thermostable properties at 40⁻50 °C. Further purification led to the isolation of eight constituents from ACFB, identified as: 25S-antcin K (1), 25R-antcin K (2), dehydrosulphurenic acid (3), 25S-antcin I (4), 25S-antcin B (5), 25R-antcin B (6), dehydroeburicoic acid (7) and eburicoic acid (8). Notably, the ACFB extract and its identified compounds, except 1, 4, and 6 demonstrated a greater effect (EC50 = 0.025⁻0.21 mg/mL) than acarbose (EC50 = 0.278 mg/mL). As such, these active compounds were determined to be new potent mushroom α-glucosidase inhibitors. These active compounds were also identified on the HPLC fingerprints of ACFB.

Abstract
Previous research demonstrated that the ethyl acetate extract from Antrodia cinnamomea suppresses the invasive potential of human breast and hepatoma cells, but the effective compounds are not identified. The main bioactive compounds of A. cinnamomea are ergostane-type triterpenoids, and the content of antcin K is the highest. The objective of this study was to evaluate the antimetastatic activity and mechanisms of antcin K purified from the fruiting body of basswood-cultivated A. cinnamomea on human liver cancer Hep 3B cells. The results showed that adhesion, migration, and invasion of Hep 3B cells were effectively inhibited by antcin K within 24 h of treatment. Antcin K not only reduced the protein expression and activity of MMP-2 and MMP-9 but also down-regulated vimentin and up-regulated E-cadherin in Hep 3B cells. In depth investigation for the molecular mechanism revealed that antcin K could reduce the protein expression of integrin β1, β3, α5, and αv and suppress phosphorylation of FAK, Src, PI3K, AKT, MEK, ERK, and JNK. These results suggested that antcin K was able to inhibit the metastasis of human hepatoma cells through suppression of integrin-mediated adhesion, migration, and invasion. Coupled with these findings, antcin K has a good potential to reduce the risk of liver cancer metastasis.

Abstract
Liver cancer is the second leading cause of cancer deaths in Taiwan as per the 2011 statistics and ranks fourth in cancer-related mortality in the world. Recent researches have shown that Antrodia cinnamomea, a Taiwan-specific medicinal mushroom, has biological activities, including hepatoprotection, anti-inflammation, antihepatitis B virus activity, and anticancer activity. In the present study, the antiproliferative activity and molecular mechanisms of antcin K, the most abundant ergostane triterpenoid from the fruiting bodies of basswood cultivated A. cinnamomea, were investigated using human hepatoma Hep 3B cells. The results showed that antcin K effectively reduced Hep 3B cells viability within 48 hours. Antcin K induced phosphatidylserine exposure, chromatin condensation, and DNA damage, but did not significantly increase autophagosome content or cause cell expansion and cell lysis. Thus, the principal mode of Hep 3B cells death induced by antcin K was apoptosis, rather than autophagy or necrosis. In-depth investigation of the molecular mechanisms revealed that antcin K first promoted reactive oxygen species generation and adenosine triphosphate depletion, leading to endoplasmic reticulum stress and resulting in mitochondrial membrane permeability changes. After losing the mitochondrial membrane potential, caspase-independent and caspase-dependent apoptosis-related proteins were released, including HtrA2, apoptotic-induced factor, endonuclease G, and cytochrome c. Cytochrome c activated caspase-9 and caspase-3, and cut downstream protein PARP, ultimately leading to cell apoptosis. These results suggested that antcin K induced mitochondrial and endoplasmic reticulum stress-mediated apoptosis in human hepatoma cells. Coupled with these findings, antcin K has a potential to be a complementary agent in liver cancer therapy.
