Abstract Wnt molecules play crucial roles in development and adult homeostasis through their receptors Frizzled proteins (Fzds). Fzds mediate canonical b-catenin pathway and various noncanonical b-catenin-independent pathways. Aberrant Fzd signaling is involved in many diseases including cancer. Wnt/b-catenin is a well-established oncogenic pathway involved in almost every aspect of tumor development. However, Fzd-mediated noncanonical Wnt pathways function as both tumor promoters and tumor suppressors depending on cellular context. Fzd-targeted therapies have proven to be effective on cultured tumor cells, tumor cell xenografts, mouse tumor models, and patient-derived xenografts (PDX). Moreover, Fzd-targeted therapies synergize with chemotherapy in preclinical models. However, the occurrence… More >

Abstract Curcumol (Cur), isolated from the Traditional Chinese Medical plant Rhizoma Curcumae, is the bioactive component of sesquiterpene reported to possess antitumor activity. However, its bioactivity and mechanisms against lung adenocarcinoma are still unclear. We investigated its effect on lung adenocarcinoma and elucidated its underlying molecular mechanisms. In vitro, Cur effectively suppressed proliferation, migration, and invasion of lung adenocarcinoma cells A549 and H460, which were associated with the altered expressions of signaling molecules, including p-AKT, p-PI3K, p-LRP5/6, AXIN, APC, GSK3 and p- -catenin, matrix metalloproteinase (MMP)-2, and MMP-9. Furthermore, Cur significantly induced cell apoptosis of A549 and H460 by promoting the… More >

Abstract The limited bioactivity of scaffold materials is an important factor that restricts the development of bone tissue engineering. Wnt3a activates the classic Wnt/β-catenin signaling pathway which effects bone growth and development by the accumulation of β-catenin in the nucleus. In this study, we fabricated 3D printed PCL scaffold with Wnt3a-induced murine bone marrow-derived stromal cell line ST2 decellularized matrix (Wnt3a-ST2-dCM-PCL) and ST2 decellularized matrix (ST2-dCM-PCL) by freeze-thaw cycle and DNase decellularization treatment which efficiently decellularized >90% DNA while preserved most protein. Compared to ST2-dCM-PCL, Wnt3a-ST2-dCM-PCL significantly enhanced newly-seeded ST2 proliferation, osteogenic differentiation and upregulated osteogenic marker genes alkaline phosphatase (Alp),… More >

Abstract Osteoporosis is a frequently occurring bone remodeling disorder worldwide with one characteristic being decreasing bone mineral density and a predisposition to bone fracture, which diminishes patients’ quality of life. Several studies showed that imbalance between the osteogenesis and adipogenesis of bone marrow mesenchymal stem cells (BMSCs) took part in the development of osteoporosis. In previous study, we found MIR22HG regulated the osteogenesis of human BMSCs positively. In this study, we found that MIR22HG was decreased during the adipogenesis of human BMSCs and exerted negative effects on adipogenesis with the involvement of Wnt/β-catenin signaling pathway both in vitro and in vivo.… More >

Abstract The present study was designed to investigate the role of estrogen receptor α (ERα) in biaxial tensile strain (BTS) regulated osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells (rBMSCs). rBMSCs were derived from rats and overexpressed ERα. The rBMSCs were subjected to BTS at 1 Hz with a strain of 2% for 4 h per day, 3 days, with or without ERα inhibitor ICI 182,780 (ICI). Then, bone mineralization was performed by Alizarin Red Staining. The markers of osteogenic differentiation and downstream Wnt3a/β-catenin signaling were detected by western blotting. Results showed that BTS enhanced the osteogenic differentiation of rBMSCs,… More >

Abstract Diabetes Mellitus is a systematic disease with complications in multi-organs, including decreased implant osseointegration and a high failure rate of dental transplants. Accumulating evidence indicates that the signaling pathway directly impacts the process of bone metabolism and inflammatory response implicated with dental implants in diabetic patients. This review summarizes the recent advance in signaling pathways regulate osseointegration and inflammatory response in dental transplantation, aiming to identify the potential therapeutic target to reduce the dental transplant failure in diabetes patients, with emphasis on the surface characteristics of the implant, inflammatory signaling, AMPK, PPARγ, WNT, ROS, and adiponectin signaling.

Abstract Chemotherapy may cause cellular oxidative stress to bone marrow. Oxidative damage of bone marrow hematopoietic microenvironment is closely related to chronic myelosuppression after chemotherapeutic treatment. Angelica sinensis polysaccharides (ASP) are major effective ingredients of traditional Chinese medicine Angelica with multi-target anti-oxidative stress features. In the current study, we investigated the protective roles and mechanisms of ASP on chemotherapy-induced bone marrow stromal cell (BMSC) damage. The human bone marrow stromal cell line HS-5 cells were divided into control group, 5-FU group, 5-FU + ASP group, and 5-FU + LiCl group to investigate the mechanism of ASP to alleviate 5-FU-induced BMSC proliferation… More >

Abstract Fibroblast growth factors (FGFs) play pivotal roles in cell migration and proliferation. However, the identity of the FGF that plays a dominant role in kidney cell proliferation remains unclear. Therefore, in this study, we investigated the dominant FGF among all FGFs. To this end, RNA-sequencing, qRT-PCR, western blotting, and ChIP assays were performed. FGF9 showed the highest expression among all FGFs, and its overexpression significantly promoted proliferation in the mouse kidney cell line C57BL/6 and increased JNK and AKT phosphorylation levels. Further, RNA-seq analysis identified 365 upregulated and 276 downregulated genes in FGF9-overexpressed cells. These differentially expressed genes were classified… More >

Abstract Glioma is one of the lethal central nervous system tumors. The infiltrative and invasive growth nature makes it difficult to identify the boundary between glioma and the normal tissues, resulting in inevitable recurrence after surgery operation. Gliomas do not metastasize, so to prevent the residual tumor from proliferating or invading is a key challenge. Previous report indicated that hypotaurine could facilitate glioma invasion and suppress demethylases’ activities. Using a hypotaurine synthesis deficient U251 cell line, we proved that the cells invasion ability was impaired. Gene expression profile analysis exhibited that knocking down one of the key enzymes of hypotaurine synthesis,… More >
