Abstract Breast cancer is the leading cause of cancer deaths in females all over the world, mainly resulting from metastasis. Previous studies have revealed that repressor element-1 (RE-1) silencing transcription (REST) acted as a tumor suppressor in breast cancer. However, the mechanism by which REST is regulated remains unknown, and its role in the metastasis in breast cancer cells remains unclear. In the present study, we showed that the expression of REST was lower in breast cancer samples than that of adjacent samples by immunohistochemical analysis, which may be due to hypermethylation of the REST promoter.… More >

Abstract JARID1B has been proven to be upregulated in many human malignancies and is correlated with tumor progression. However, its expression and clinical significance in osteosarcoma are still unclear. Thus, the aim of this study was to explore the effects of JARID1B in osteosarcoma tumorigenesis and development. In this study, we found that the expression levels of JARID1B in osteosarcoma tissues were significantly higher than those in corresponding noncancerous bone tissues. In addition, JARID1B upregulation occurred more frequently in osteosarcoma specimens from patients with a poor prognosis. After JARID1B transfection in osteosarcoma cells, cell proliferation was More >

Abstract Multiple myeloma (MM) is a hematopoietic malignancy characterized by the clonal proliferation of antibodysecreting plasma cells. Bortezomib (BZM), the first FDA-approved proteasome inhibitor, has significant antimyeloma activity and prolongs the median survival of MM patients. However, MM remains incurable predominantly due to acquired drug resistance and disease relapse. -Catenin, a key effector protein in the canonical Wnt signaling pathway, has been implicated in regulating myeloma cell sensitivity to BZM. Decitabine (DAC) is an epigenetic modulating agent that induces tumor suppressor gene reexpression based on its gene-specific DNA hypomethylation. DAC has been implicated in modulating Wnt/… More >

Abstract Lignin is a natural biopolymer with a complex three-dimensional network, commercially obtained from waste liquid of paper pulp and bioethanol production, and could be a candidate for preparation of environment-friendly bio-based polyphenol material. In the present work, the demethylated wheat straw alkali lignin (D-Lig), prepared by demethylation of wheat straw alkali lignin (Lig) using an in-situ generated Lewis acid, was used to synthesize bio-based phenol formaldehyde resin adhesive (D-LPF) applied in plywood. Effects of synthetic process’s factors, including lignin substitution for phenol, NaOH concentration and molar ratio of formaldehyde to phenol, on the bonding strength and… More >
