Trophoblast stem cells (TSCs), the precursors of placental cells, are effective for studying placental formation in vitro. Using a dual inhibition (2i) medium and mixed L-Wnt3a/mouse embryonic fibroblast feeder cells, we previously established the bovine trophoblast cell line BTS-1. In this study, we used bovine fetal fibroblasts and added Wnt3a to the 2i medium to establish another bovine TSC line (BTSW). BTSW cells expressed pluripotency markers, including NANOG, SOX2, OCT4, TRA-1-60, TRA-1-81, SSEA4, CDH1, and KRT18, and TSC markers CDX2, TEAD4, and ESRRB...

Deregulation of microRNAs (miRNAs) has been widely reported in retinoblastoma (RB), and the aberrantly expressed miRNAs may serve as crucial epigenetic regulators in the occurrence and development of RB. Therefore, the identification of dysregulated miRNAs in RB may be useful for the development of effective targets for the therapy patients with this disease. miRNA (miR)‑485‑5p (miR‑485) is deregulated in multiple human cancer types and serves crucial roles in their progression and development. However, the expression pattern of miR‑485 and its role in RB have not been well investigated...

Gfi1b is a transcriptional repressor expressed in hematopoietic stem cells (HSCs) and megakaryocytes (MKs). Gfi1b deficiency leads to expansion of both cell types and abrogates the ability of MKs to respond to integrin. Here we show that Gfi1b forms complexes with β-catenin, its co-factors Pontin52, CHD8, TLE3 and CtBP1 and regulates Wnt/β-catenin-dependent gene expression. In reporter assays, Gfi1b can activate TCF-dependent transcription and Wnt3a treatment enhances this activation. This requires interaction between Gfi1b and LSD1 and suggests that a tripartite β-catenin/Gfi1b/LSD1 complex exists, which regulates Wnt/β-catenin target genes...

Appropriate Wnt morphogen secretion is required to control animal development and homeostasis. Although correct Wnt globular structure is essential for secretion, proteins that directly mediate Wnt folding and maturation remain uncharacterized. Here, we report that protein disulfide isomerase-1 (PDI-1), a protein-folding catalyst and chaperone, controls secretion of the Caenorhabditis elegans Wnt ortholog EGL-20. We find that PDI-1 function is required to correctly form an anteroposterior EGL-20/Wnt gradient during embryonic development...

Transmembrane prostate androgen-induced protein (TMEPAI) is a type I transmembrane protein induced by several intracellular signaling pathways such as androgen, TGF-β, EGF, and Wnt signaling. It has been reported that TMEPAI functions to suppress TGF-β and androgen signaling but here, we report a novel function of TMEPAI in Wnt signaling suppression. First, we show that TMEPAI significantly inhibits TCF/LEF transcriptional activity stimulated by Wnt3A, LiCl, and β-catenin. Mechanistically, TMEPAI overexpression prevented β-catenin accumulation in the nucleus and TMEPAI knockout in triple negative breast cancer cell lines promoted β-catenin stability and nuclear accumulation together with increased mRNA levels of Wnt target genes AXIN2 and c-MYC...

Captopril (Cap) as angiotensin-converting enzyme inhibitor (ACEi) is commonly used to treat hypertension and some types of congestive heart failure. However, few studies reported on whether Cap exerts a protective effect on myocardial apoptosis induced by transverse aortic constriction (TAC). This study aimed at investigating the possible mechanism of Cap on myocardial apoptosis induced by pressure overload. Results showed that Cap significantly decreased heart-to-body weight ratios (HBWR). Cap markedly improved cardiac function, and reduced inner diameter of ascending aorta (Asc Ao) in TAC mice as shown by echocardiography...

BACKGROUND: Mesenchymal stem cells (MSCs) are increasingly being applied as a therapy for liver fibrosis. Exosomes possess similar functions to their parent cells; however, they are safe and effective cell-free reagents with controllable and predictable outcomes. In this study, we investigated the therapeutic potential and underlying molecular mechanism for human bone mesenchymal stem cells-derived exosomes (hBM-MSCs-Ex) in the treatment of liver fibrosis. METHODS: We established an 8-week CCl4 -induced rat liver fibrosis model, after which, we administered hBM-MSCs-Ex in vivo for 4 weeks...

The establishment of neuronal polarity is driven by cytoskeletal remodeling that stabilizes and promotes the growth of a single axon from one of the multiple neurites. The importance of the local microtubule stabilization in this process has been revealed however, the external signals initiating the cytoskeletal rearrangements are not completely understood. In this study, we show that local activation of the canonical Wnt pathway regulates neuronal polarity and axonal outgrowth. We found that in the early stages of neuronal polarization, Wnt3a accumulates in one of the neurites of unpolarized cells and thereby could determine axon positioning...

The bromodomain and extra-terminal domain (BET) protein BRD4 is emerging as a potential target for cancer therapy. However, BRD4 roles in regulating the stemness of gastric cancer cells are unclear. Here, we demonstrated that BRD4 expression was significantly increased in gastric cancer tissues, cell spheroids, and BRD4 knockdown attenuated the stemness of gastric cancer cells characterized as the decrease of stemness markers expression, capacity of cells spheroids formation and ALDH1 activity. Importantly, BRD4 expression was negatively correlated with overall survival, first progression survival and post progression survival of gastric cancer patients...

Growing evidences demonstrate that long non-coding RNAs (lncRNAs) contribute to the cancer initiation and progression and are considered as promising diagnostic and therapeutic targets of multiple cancers. However, the definite role of LINC00536 in bladder cancer (BC) remains unclear. In the present study, we found LINC00536 expression was highly expressed in BC tissues compared with controls and negatively associated with survival rate in BC patients. Gain-of-function assays indicated that LINC00536 overexpression promoted the proliferation, migration and invasion, whereas LINC00536 knockdown attenuated the cell phenotypes above in BC cell lines...

Osteopontin (OPN) plays an important role in the bone regeneration process. Previous investigation showed that recombinant human OPN was able to express in Nicotiana benthamiana leaves and induced the osteogenic related genes. Nevertheless, the purification of OPN from plant proteins with Ni affinity chromatography was still not effective enough. To improve the quality of protein expression and purification in plants, we constructed an Fc-based form of OPN. The complete OPN protein was fused to the human IgG1 Fc domain...

Interleukin‑22 (IL‑22) has both pro‑inflammatory and anti‑inflammatory properties in a number tissues depending on the environment. Epithelial cells usually have a rapid turnover and are fueled by tissue stem cells. However, the question of whether IL‑22 regulates tissue homeostasis through the modulation of stem cells remains unanswered. In this study, we investigated the role of IL‑22 in the homeostasis of intestinal epithelial cells (IECs) during inflammation through a 3D organoid culture system...

BACKGROUND: In tissue microarrays, immunostaining of the enzyme arylsulfatase B (ARSB; N-acetylgalactosamine-4-sulfatase) was less in recurrent prostate cancers and in cancers with higher Gleason scores. In cultured prostate stem cells, decline in ARSB increased Wnt signaling through effects on Dickkopf Wnt Signaling Pathway Inhibitor (DKK)3. The effects of androgen exposure on ARSB and the impact of decline in ARSB on Wnt signaling in prostate tissue were unknown. METHODS: Epithelial and stromal tissues from malignant and normal human prostate were obtained by laser capture microdissection...

In type 2 cardiorenal syndrome, chronic heart failure is thought to cause or promote chronic kidney disease; however, the underlying mechanisms remain poorly understood. We investigated the role of Wnt signaling in heart and kidney injury in a mouse model of cardiac hypertrophy and heart failure induced by transverse aortic constriction (TAC). At 8 weeks after TAC, cardiac hypertrophy, inflammation, and fibrosis were prominent, and echocardiography confirmed impaired cardiac function. The cardiac lesions were accompanied by upregulation of multiple Wnt ligands and activation of β-catenin, as well as activation of the renin-angiotensin system (RAS)...

Background: Bone marrow derived stromal stem cells (BMSCs) are a clonogenic cell population that is characterized by self-renewal capacity and differentiation potential into osteoblasts, and other mesenchymal cell types. Mouse BMSCs (mBMSCs) are difficult to be cultured and propagated in vitro due to their replicative senescent phenotype, heterogeneity and high contamination with plastic adherent hematopoietic progenitors (HPCs). In this study, we described long-term culture of homogenous population of mBMSCs using simple and highly reproducible approach based on frequent subculturing (FS) at fixed split ratio in the presence of basic fibroblast growth factor (bFGF)...
