    Abstract We investigated the anti-EMT and antifibrotic effects of coenzyme Q0 (CoQ0), a quinone derivative from Antrodia camphorata, in TGF-β-stimulated adult retinal pigment epithelial 19 (ARPE-19) cells. Results showed that CoQ0 treatment reversed TGF-β-stimulated morphological changes from an epithelial to a fibroblastic phenotype in ARPE-19 cells. CoQ0 exhibited anti-EMT effects by impeding TGF-β-stimulated migration and invasion in ARPE-19 cells. Notably, CoQ0 triggered the epithelial marker E-cadherin and suppressed the mesenchymal marker N-cadherin expression in nonstimulated or TGF-β-stimulated ARPE-19 cells. Moreover, CoQ0 attenuated EMT and fibrotic Vimentin, MMP-9/-2, Slug, α-SMA, and VEGF expression in nonstimulated or TGF-β-stimulated ARPE-19 cells. Interestingly, CoQ0 inhibited TGF-β-induced intracellular ROS production by activating Nrf2 nuclear translocation and upregulating the HO-1, γ-GCLC, and NQO-1 enzymes in ARPE-19 cells. Moreover, Nrf2 silencing reversed TGF-β-induced ROS-mediated anti-EMT (E-cadherin/N-cadherin/Slug) and antifibrotic (α-SMA) effects in CoQ0-treated ARPE-19 cells. Therefore, CoQ0 could be utilized to treat age-related macular degeneration and proliferative vitreoretinopathy.

    Abstract This study aims to investigate the wound-healing effectiveness of the phenolic compound, naringin, both in vitro and in vivo. Male mice were shaved on their dorsal skin under isoflurane, a biopsy punch was made in four symmetrical circular resection windows (6 mm) to induce a wound. These excision wounds were used to study the topical effects of naringin in terms of various biochemical, molecular, and histological parameters. We observed a significant recovery in the wound area. Increased levels of MMP-2, 9, 14, TIMP-2, VEGF-A, and VEGF-R1 were induced by naringin in the HaCaT cells. The time course experiments further revealed that levels of VEGF-A and B increased within 36 h; whereas levels of VEGF-C decreased. In line with this, VEGF-R3 levels, but not VEGF-R1 and 2 levels, increased soon after stimulation; although the increase subsided after 36 h. Additionally, naringin cream upregulated wound healing in vitro. The blockage of VEGF by Bevacizumab abolished the function of naringin cream on cell migration. Histological alterations in the wounded skin were restored by naringin cream, which accelerated wound healing via upregulated expression of growth factors (VEGF-A, B, and C and VEGF-R3), and thus increased MMP-2, 9, 14 expressions.

    Abstract Pterostilbene (Pt) is a natural polyphenol found in blueberries and several grape varieties. Pt's pharmacological importance was well documented. Nevertheless, the depigmenting effects are not demonstrated. We evaluated the Pt's depigmenting effects through autophagy induction in B16F10 cells and inhibition of UVA (3 J/cm2)-irradiated α-MSH in keratinocyte HaCaT cells via Nrf2-mediated antioxidant pathways. Pt (2.5–5μM) attenuated ROS production and downregulated the POMC/α-MSH pathway in HaCaT cells. The conditioned medium-derived from UVA-irradiated HaCaT pretreated with Pt suppressed melanogenesis in B16F10 through MITF-CREB-tyrosinase pathway downregulation. Interestingly, Pt-induced HaCaT autophagy was revealed by enhanced LC3-II accumulation, p62/SQSTM1 activation, and AVO formation. Pt significantly decreased melanosome gp100 but increased LC3-II levels in HaCaT cells exposed to B16F10-derived melanin. Pt activated and facilitated the Nrf2 antioxidant pathway in HaCaT cells leading to increased HO-1, γ-GCLC, and NQO-1 antioxidant protein expression. ERK, AMPK, and ROS pathways mediate the Nrf2 activation. However, Nrf2 knockdown suppressed Pt's antioxidant ability leading to uncontrolled ROS and α-MSH levels after UVA-irradiation suggested the essentiality of the Nrf2 pathway. Moreover, in α-MSH-stimulated B16F10 cells, Pt (10–30 μM) downregulated the MC1R, MITF, tyrosinase, TRP-1/-2, and melanin expression. Further, Pt showed potent anti-melanogenic effects through autophagy induction mechanism in B16F10 cells, verified by increased LC3-II/p62 levels, AVO formation, and Beclin-1/Bcl-2 ratio, decreased ATG4B levels and PI3K/AKT/mTOR pathway. Transmission electron microscopy provided direct evidence by showing autophagosomes engulfing melanosomes following Pt treatment in α-MSH-stimulated B16F10 cells. Moreover, Pt-induced anti-melanogenic activity through the downregulation of CREB-MITF pathway-mediated TRP-1/-2, tyrosinase expressions, melanosome formation, and melanin synthesis was substantially ...

    Abstract The medicinal fungus Ganoderma, known in Chinese as Lingzhi or Reishi, traditionally has various medicinal uses and has been employed in cancer treatment in Asia for centuries. This study used ethanol-extracted Ganoderma tsugae (GT) and examined its antitumor activities on human chronic myeloid leukemia cells as well as its molecular mechanism of action. Treatment with GT (200–400 μg/mL) significantly reduced cell viability and caused G2/M arrest in K562 cells. In addition, GT induced mitochondrial and death receptor mediated apoptosis, correlated with DNA fragmentation, followed by cytochrome c release, caspase-3/8/9 activation, PARP cleavage, Fas activation, Bid cleavage, and Bax/Bcl-2 dysregulation. Cytoprotective autophagy was found to be induced by GT, as was revealed by increased LC3-II accumulation, Beclin-1/Bcl-2 dysregulation, acidic vesicular organelle formation, and p62/SQSTM1 activation. Notably, pretreatment of cells with the autophagy inhibitors 3-MA and CQ enhanced GT-induced apoptosis. Interestingly, reactive oxygen species production in cells was not triggered by GT administration; equally, the antioxidant N-acetylcysteine was found to be incapable of preventing apoptosis and autophagy induced by GT treatment. Finally, this study discovered that cytoprotective autophagy induced by GT was associated with EGFR and PI3K/AKT/mTOR signaling cascade suppression. In summary, GT demonstrated antitumor activity against human chronic myeloid leukemia.

    Abstract Antrodia camphorata (AC) is a well known traditional Chinese medicinal mushroom in Taiwan, has been used to treat various diseases including cancer.In this study, we investigated the anti-metastatic and anti-EMT properties of a fermented culture broth of AC in human colon SW480claudin−1− and metastatic SW620claudin−1+ cancer cells in vitro.AC down-regulates claudin-1 and inhibits the proliferation and colony-formation abilities of both SW620claudin−1+ and SW480claudin−1− cells. In highly metastatic SW620claudin−1+ cells, non-cytotoxic concentrations of AC significantly inhibited migration/invasion, accompanied by the down-regulation of MMP-2 and MMP-9 proteins. AC decreased nuclear translocation of Wnt/β-catenin through a GSK3β-dependent pathway. AC consistently inhibited EMT by up-regulating the epithelial and downregulating the mesenchymal marker proteins. In SW480claudin−1− cells, AC suppressed migration/invasion potentially through the inhibition of the PI3K/AKT/NFκB signaling pathways without altering the expression levels of β-catenin and GSK3β proteins.Altogether, this study demonstrates the anti-metastatic and anti-EMT activities of AC, which may contribute to the development of a chemopreventive agent for colon cancer.

    Abstract Antrodia salmonea (AS), is a well-known folk medicinal mushroom in Taiwan, has been reported to exhibit anti-oxidant, anti-angiogenic, and anti-inflammatory effects.In the present study, we examined the effects of AS on cell-cycle arrest in vitro in MDA-MB-231 cells and on tumor regression in vivo using an athymic nude mice model.AS (0–200μg/mL) treatment significantly induced G2 cell-cycle arrest in MDA-MB-231 cells by reducing the levels of cyclin B1, cyclin A, cyclin E, and CDC2 proteins. In addition, N-acetylcysteine (NAC) pretreatment prevented AS induced G2 cell-cycle arrest, indicating that ROS accumulation and subsequent cell cycle arrest might be a major mechanism of AS-induced cytotoxicity. Further, AS treatment decreased COX-2 expression and induced PARP cleavage was significantly reversed by NAC pretreatment in MDA-MB-231 cells. The in vivo study results revealed that AS treatment was effective in terms of delaying the tumor incidence and reducing the tumor growth in MDA-MB-231-xenografted nude mice. TUNEL assay, immunohistochemical staining and Western blotting confirmed that AS significantly modulated the xenografted tumor progression as demonstrated by induction of apoptosis, autophagy, and cell-cycle arrest.Our data strongly suggest that Antrodia salmonea could be an anti-cancer agent for human breast cancer.

    Abstract We investigated the in vitro and in vivo anticancer properties of Antrodia salmonea (AS), a well-known edible/medicinal mushroom in Taiwan, on human triple-negative breast cancer (MDA-MB-231) cells and xenografted nude mice; and revealed the underlying molecular mechanisms involved in autophagic- and apoptotic-cell death. Treatment of MDA-MB-231 cells with fermented culture broth of AS (0–200 μg/mL) inhibited cell viability/growth. AS-induced autophagy was evidenced via increased LC3-II accumulation, GFP-LC3 puncta and AVOs formation in MDA-MB-231 cells. These events are associated with increased ATG7, decreased p-mTOR, vanished SQSTM1/p62 expressions and dysregulated Beclin-1/Bcl-2 ratio. AS-induced apoptosis/necrosis through increased DNA fragmentation, Annexin-V/PI stained cells and Bax expression. Both mitochondrial (caspase-9/caspase-3/PARP) and death-receptor (caspase-8/FasL/Fas) signaling pathways are involved in execution of apoptosis. Interestingly, blockade of AS-induced ROS production by N-acetylcysteine pretreatment substantially attenuated AS-induced autophagy, mitochondrial dysfunction and autophagic/apoptotic-cell death. Inhibition of apoptosis by Z-VAD-FMK suppressed AS-induced autophagic-death (decreased LC3-II/AVOs). Similarly, inhibition of autophagy by 3-methyladenine/chloroquine diminished AS-induced apoptosis (decreased DNA fragmentation/caspase-3) in MDA-MB-231 cells. Bioluminescence imaging further confirmed that AS inhibited breast tumor growth in living MDA-MB-231-luciferase-injected nude mice. Taken together, AS crucially involved in execution/propagation of autophagic- or apoptotic-death of MDA-MB-231 cells, and decreased tumor growth in xenografted nude mice.

    Abstract Abstract Coenzyme Q0 (CoQ0, 2,3-dimethoxy-5-methyl-1,4-benzoquinone) has been reported to exert anticancer properties against human breast/lung cancer cells. This study investigated the in vitro and in vivo anticancer properties of CoQ0 on human ovarian carcinoma (SKOV-3) cells and xenografted nude mice, and revealed the underlying molecular mechanism. CoQ0 induced G2/M arrest through downregulation of cyclin B1/A and CDK1/K2 expressions. CoQ0-induced autophagy as a survival mechanism was evidenced by increased accumulation of LC3-II, GFP-LC3 puncta, AVOs formation and Beclin-1/Bcl-2 dysregulation. Increased TUNEL-positive cells and Annexin-V/PI stained cells indicated CoQ0-induced late apoptosis. Both mitochondrial (caspase-3, PARP and Bax/Bcl-2 dysregulation) and ER stress (caspase-12 and Hsp70) signals are involved in execution of apoptosis. Interestingly, CoQ0-induced apoptosis/autophagy is associated with suppression of HER-2/neu and PI3K/AKT signalling cascades. CoQ0 triggered intracellular ROS production, whereas antioxidant N-acetylcysteine prevented CoQ0-induced apoptosis, but not autophagy. Inhibition of apoptosis by Z-VAD-FMK suppressed CoQ0-induced autophagy (diminished LC3-II/AVOs), indicates CoQ0-induced apoptosis led to evoke autophagy. Contrary, inhibition of autophagy by 3-MA/CQ potentiated CoQ0-induced apoptosis (increased DNA fragmentation/PARP cleavage). Furthermore, CoQ0 treatment to SKOV-3 xenografted nude mice reduced tumor incidence and burden. Histopathological analyses confirmed that CoQ0 modulated xenografted tumor progression by apoptosis induction. Our findings emphasize that CoQ0 triggered ROS-mediated apoptosis and cytoprotective autophagy.

    Abstract This study investigated the dermato-protective effects of lucidone, a cyclopentenedione from Lindera erythrocarpa dried fruits, against UVA-induced oxidative stress and apoptosis in human keratinocytes (HaCaT). Pre-treatment with lucidone (1–4 µM) significantly protects keratinocytes from UVA (15 J/cm2)-induced cell death, excessive ROS generation, LDH release, lipid peroxidation, and DNA damage. Notably, lucidone inhibited the UVA-induced apoptosis of HaCaT cells as measured by a reduction of DNA fragmentation, mitochondria dysfunction, and Bcl-2/Bax dysregulation. Furthermore, antioxidant potential of lucidone was directly correlated with the induction of antioxidant genes, including HO-1, NQO-1, and γ-GCLC by transcriptional activation of Nrf2. Treatment with hydrogen peroxide showed cellular byproducts of UVA irradiation-induced cell death, LDH release, and ROS generation, but these phenomena were inhibited by pre-treatment of lucidone. Besides, in Nrf2 knock-down cells, lucidone failed to protect UVA-induced oxidative stress or cell death. Our findings suggest that lucidone is capable of protecting skin cells from UVA-irradiated damage.

    Abstract Antrodia camphorata (AC) is well known in Taiwan as a traditional Chinese medicine. The aim of this study was to investigate whether a fermented culture broth of AC could inhibit melanoma proliferation and progression via suppression of the Wnt/β-catenin signaling pathway. In this study, we observed that AC treatment resulted in decreased cell viability and disturbed Wnt/β-catenin cascade in B16F10 and/or B16F1 melanoma cells. This result was accompanied by a decrease in the expression of Wnt/β-catenin transcriptional targets, including c-Myc and survivin. Furthermore, treatment of melanoma cells with AC resulted in a significant increase in apoptosis, which was associated with DNA fragmentation, cytochrome c release, caspase-9 and -3 activation, PARP degradation, Bcl-2/Bax dysregulation, and p53 expression. We also observed that AC caused G1 phase arrest mediated by a downregulation of cyclin D1 and CDK4 and increased p21 and p27 expression. In addition, we demonstrated that non- and subcytotoxic concentrations of AC markedly inhibited migration and invasion of highly metastatic B16F10 cells. The antimetastatic effect of AC was further confirmed by reductions in the levels of MMP-2, MMP-9, and VEGF expression. These results suggest that Antrodia camphorata may exert antitumor activity by downregulating the Wnt/β-catenin pathways.
