(Thio)chromenone derivatives exhibit anti-metastatic effects through selective inhibition of uPAR in cancer cell lines: discovery of an uPAR-targeting fluorescent probe.

A class of (thio)chromenone derivatives has been identified as suitable ligands for uPAR, a glycoprotein with a prognostic value in a large number of human cancers. The (thio)chromenone agents actively inhibited the binding of uPAR to uPA with a binding affinity of 18.6 nM, reducing cell migration in the wound healing assay by up to 40% without apparent cell motility.

Automatic classification of 3D positional relationship between mandibular third molar and inferior alveolar canal using a distance-aware network.

The purpose of this study was to automatically classify the three-dimensional (3D) positional relationship between an impacted mandibular third molar (M3) and the inferior alveolar canal (MC) using a distance-aware network in cone-beam CT (CBCT) images. We developed a network consisting of cascaded stages of segmentation and classification for the buccal-lingual relationship between the M3 and the MC. The M3 and the MC were simultaneously segmented using Dense121 U-Net in the segmentation stage, and their buccal-lingual relationship was automatically classified using a 3D distance-aware network with the multichannel inputs of the original CBCT image and the signed distance map (SDM) generated from the segmentation in the classification stage.

Amelioration of alcohol‑induced gastric mucosa damage by oral administration of food‑polydeoxyribonucleotides.

Gastritis refers to inflammation caused by injury to the gastric epithelium, which is usually due to excessive alcohol consumption and prolonged use of nonsteroidal anti‑inflammatory drugs. Millions of individuals worldwide suffer from this disease. However, the lack of safe and promising treatments makes it urgent to explore and develop leads from natural resources.

Mistletoe Extract Targets the STAT3-FOXM1 Pathway to Induce Apoptosis and Inhibits Metastasis in Breast Cancer Cells.

Mistletoe extracts ( L.) have been widely used as complementary and alternative medicines for the treatment of cancer, and their cytotoxic effects have been reported on various types of cancer. However, the molecular targets of mistletoe extracts have not been well studied.

DDIAS promotes STAT3 activation by preventing STAT3 recruitment to PTPRM in lung cancer cells.

DNA damage-induced apoptosis suppressor (DDIAS) regulates cancer cell survival. Here we investigated the involvement of DDIAS in IL-6-mediated signaling to understand the mechanism underlying the role of DDIAS in lung cancer malignancy. We showed that DDIAS promotes tyrosine phosphorylation of signal transducer and activator of transcription 3 (STAT3), which is constitutively activated in malignant cancers.

Metformin selectively targets 4T1 tumorspheres and enhances the antitumor effects of doxorubicin by downregulating the AKT and STAT3 signaling pathways.

Recent studies have reported that metformin (Met), the first-line medication for the treatment of type 2 diabetes, exhibited anticancer and chemoprotective effects in diverse cancer cells. In this study, we investigated the effects of Met on the drug-resistance of 4T1 murine breast cancer tumorspheres (TS) and the mechanism responsible for its drug-resistance. 4T1 TS exhibited accumulations of cells at the G/G phase compared with cells in monolayer culture, which suggested the majority of cells in TS were quiescent.

Arsenic May Act as a Pro-Metastatic Carcinogen Through Promoting Tumor Cell-Induced Platelet Aggregation.

Arsenic-associated carcinogenesis and related mortality are a major public health concern worldwide; however, the underlying mechanism of action remains unclear. Here, we demonstrated that arsenic promotes tumor metastasis by stimulating tumor cell-platelet aggregation (TCPA), which can ultimately increase cancer-related mortality. In freshly isolated human platelets in vitro, arsenic potentiated TCPA prompted by diverse cancer cell lines, which was attributable to increased platelet reactivity to TCPA with respect to thrombin generation and P-selectin, GPIIb/IIIa expression.

Anti-metastatic potential of a proton beam is regulated by p38 MAPK/c-Fos signaling pathway in TPA-treated HepG2 human hepatocellular carcinoma.

A proton beam therapy is considered the next generation radio-therapeutic tool for liver cancer treatments. However, its effect on metastasis has not been fully elucidated. Herein, we assessed the effects of a proton beam on the metastatic potential in HepG2, Hep3B and SK-Hep1 hepatocellular carcinomas.

The prevention of TNF-α/IFN-γ mixture-induced inflammation in human keratinocyte and atopic dermatitis-like skin lesions in Nc/Nga mice by mineral-balanced deep sea water.

Atopic dermatitis (AD) is a chronic inflammatory skin disease caused by environmental and chemical allergens. Despite the complexity of its pathogenesis, many investigations have shown that substances having anti-inflammatory activities alleviated the pathology of AD. Here, we evaluated the effects of mineral-balanced deep sea water (DSW) on AD-like skin damage in both in vitro and in vivo.

Refined Deep-Sea Water Suppresses Inflammatory Responses via the MAPK/AP-1 and NF-κB Signaling Pathway in LPS-Treated RAW 264.7 Macrophage Cells.

Atopic dermatitis (AD) is a type of inflammatory skin disease caused by genetics, immune system dysfunction, and environmental stresses. It is, however, still considered to be a refractory disease. Macrophages are inflammatory immune cells that infiltrate the skin and induce inflammation.

The inhibitory effects of deep-sea water on doxorubicin‑induced epithelial-mesenchymal transition.

It has been revealed that the induction of epithelial‑mesenchymal transition (EMT) is associated with drug resistance, leading to tumor recurrence and metastasis. Recent studies have shown that chemotherapeutic agents, besides their therapeutic effects, can induce EMT and enhance invasive and metastatic properties of tumor cells. Previously, we revealed that deep-sea water (DSW) exhibited antimetastatic effects in several human cancer cell lines.

Deep sea water improves hypercholesterolemia and hepatic lipid accumulation through the regulation of hepatic lipid metabolic gene expression.

A high‑fat diet or high‑cholesterol diet (HCD) is a major cause of metabolic diseases, including obesity and diabetes; vascular diseases, including hypertension, stroke and arteriosclerosis; and liver diseases, including hepatic steatosis and cirrhosis. The present study aimed to evaluate the effects of deep sea water (DSW) on rats fed a HCD. DSW decreased HCD‑induced increases in total cholesterol and low‑density lipoprotein (LDL) cholesterol in the blood, and recovered high‑density lipoprotein cholesterol.

The anti-metastatic effects of the phytoestrogen arctigenin on human breast cancer cell lines regardless of the status of ER expression.

Arctigenin is a plant lignan extracted from Arctium lappa that has been shown to have estrogenic properties. In spite of the health benefits of phytoestrogens reducing the risk of osteoporosis, heart disease, and menopausal symptoms, its benefits against the risk of breast cancer have not been fully elucidated. Thus, we investigated the effects of arctigenin on metastasis of breast cancer using both estrogen receptor (ER)-positive MCF-7 and ER-negative MDA-MB-231 human breast cancer cell lines to see if the effects are dependent on the status of ER expression.

Suppressive effects of a proton beam on tumor growth and lung metastasis through the inhibition of metastatic gene expression in 4T1 orthotopic breast cancer model.

A proton beam is a next generation tool to treat intractable cancer. Although the therapeutic effects of a proton beam are well known, the effect on tumor metastasis is not fully described. Here, we investigated the effects of a proton beam on metastasis in highly invasive 4T1 murine breast cancer cells and their orthotopic breast cancer model.

Crosstalk between Wnt signaling and Phorbol ester-mediated PKC signaling in MCF-7 human breast cancer cells.

Although many studies have implicated the crosstalk between the Wnt and PKC signaling pathways in tumor initiation and progression, the molecular roles of PKC isoforms in the Wnt signaling pathway remain poorly understood. In this study, we explored the contribution of PKC isoforms to canonical and noncanonical Wnt signaling pathway in mediating cell migration and an epithelial-mesenchymal transition (EMT). When MCF-7 cells were treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) for up to 3 weeks, the effect of TPA on Wnt signaling pathway was dramatically different depending on the exposure time.

Lapatinib sensitizes quiescent MDA-MB-231 breast cancer cells to doxorubicin by inhibiting the expression of multidrug resistance-associated protein-1.

The quiescent state plays an important role in tumor recurrence because it protects cancer cells from chemotherapy. Previously, we optimized tumorsphere cultures for in vitro screening methods for targeting quiescent cell population since the majority of cells in tumorspheres are quiescent. In this study, we analyzed efficacies of current chemotherapeutics in tumorsphere assays to seek better strategies for eradicating quiescent cell population.

Lapatinib enhances the cytotoxic effects of doxorubicin in MCF-7 tumorspheres by inhibiting the drug efflux function of ABC transporters.

Increasing evidences indicate that cancer stem cells are resistant to chemotherapy due to their cell quiescence and the expression of ATP-binding cassette (ABC) transporters. In this study, we utilized tumorsphere cultures to seek better strategies to overcome chemoresistance since tumorsphere cultures have been used widely for the enrichment of cancer stem cells. We found that tumorspheres generated from MCF-7 human breast cancer cells exhibited high proportions of quiescent cells and expressed MDR-1 at elevated levels, leading to resistance to 5-fluorouracil, paclitaxel, and doxorubicin.

Metastatic potential in MDA-MB-231 human breast cancer cells is inhibited by proton beam irradiation via the Akt/nuclear factor-κB signaling pathway.

A previous study has revealed that proton beam irradiation affects cell migration in MDA-MB-231 human breast cancer cells. Cyclooxygenase-2 (COX-2) and matrix metalloproteinase‑9 (MMP-9) are highly expressed in various cancers, such as colon, lung and breast cancer, and enhance cell migration and metastasis in vitro and in vivo. In the present study, the effects of proton beam irradiation on COX-2 and MMP-9 expression levels in MDA-MB‑231 human breast cancer cells were investigated, along with the signaling pathway involved in the proton beam irradiation‑mediated antimetastatic effect.

Mineral-enriched deep-sea water inhibits the metastatic potential of human breast cancer cell lines.

Recently, the scientific community has begun to establish the health benefits of deep-sea water (DSW) due to its enrichment in nutrients and minerals. In this study, we investigated the effects of deep-sea water (DSW) on the metastatic potential of two human breast cancer cell lines exhibiting highly different phenotypes. MDA-MB-231 cells exhibit invasive/metastatic tumor features with rapid migration ability and high endogenous expression of TGF-β and Wnt5a.

Genetic modification of primate amniotic fluid-derived stem cells produces pancreatic progenitor cells in vitro.

Insulin therapy for type 1 diabetes does not prevent serious long-term complications including vascular disease, neuropathy, retinopathy and renal failure. Stem cells, including amniotic fluid-derived stem (AFS) cells - highly expansive, multipotent and nontumorigenic cells - could serve as an appropriate stem cell source for β-cell differentiation. In the current study we tested whether nonhuman primate (nhp)AFS cells ectopically expressing key pancreatic transcription factors were capable of differentiating into a β-cell-like cell phenotype in vitro.

Surface immobilization of MEPE peptide onto HA/β-TCP ceramic particles enhances bone regeneration and remodeling.

Calcium phosphate ceramics have been widely used as scaffolds for bone regeneration. Here, to improve the osteogenic potential of hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) and to apply the bioactive peptide in situ, matrix extracellular phosphoglycoprotein (MEPE) peptide, which has been shown to stimulate osteoblast differentiation, was covalently and directionally immobilized on HA/β-TCP particles. The free-hydroxyl groups on the surface of the HA/β-TCP particles were sequentially conjugated with APTES, PEG-(SS)(2), and the synthetic MEPE peptide.
