Avian species have a unique integument covered with feathers. Skin morphogenesis is a successive and complex process. To date, most studies have focused on a single developmental point or stage. Fewer studies have focused on whole transcriptomes based on the time-course of embryo integument development. To analyze the global changes in gene expression profiles, we sequenced the transcriptome of chicken embryo skin samples from day 6 to day 21 of incubation and identified 5830 differentially expressed genes (DEGs)...

The Müllerian ducts are part of the embryonic urogenital system. They give rise to mature structures that serve a critical function in the transport and development of the oocyte and/or embryo. In most vertebrates, both sexes initially develop Müllerian ducts during embryogenesis, but they regress in males under the influence of testis-derived Anti-Müllerian Hormone (AMH). A number of regulatory factors have been shown to be essential for proper duct development, including Bmp and Wnt signaling molecules, together with homeodomain transcription factors such as PAX2 and LIM1...

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortalities worldwide, yet this condition remains a poorly understood malignancy, and the subgroup of cancer stem cells (CSCs) leading to therapeutic resistance and adverse prognosis have not been well studied. CSCs frequently undergo symmetric division, which facilitates expansion of the stem cell pool, contributing to long-term relapse and therapy failure. CCAT1 could act as a miRNA sponge to influence downstream genes; however, its roles in NSCLC stem cell are unclear...

This study investigated the effects of microRNA-135a (miR-135a) targeting of glycogen synthase kinase 3β (GSK3β) on the epithelial-mesenchymal transition (EMT), migration and invasion of bladder cancer (BC) cells by mediating the Wnt/β-catenin signaling pathway. BC and adjacent normal tissues were collected from 165 BC patients. Western blotting and quantitative real-time PCR were used to detect the expression of GSK3β, β-catenin, cyclinD1, E-cadherin, vimentin and miR-135a in BC tissues and cells. Cells were assigned to blank, negative control (NC), miR-135a mimics, miR-135a inhibitors, small interfering RNA (siRNA)-GSK3β or miR-135a inhibitors+siRNA-GSK3β groups...

Biomaterials with excellent osteogenic and angiogenic activities are desirable to repair massive bone defects. Decellularized matrix from porcine small intestinal submucosa (SIS) has attracted particular attention for tissue regeneration because it has strong angiogenic effects and retains plentiful bioactive components. However, it has inferior osteoinductivity and osteoconductivity. In this study, we developed porous composite of SIS combined with mesoporous bioactive glass (SIS/MBG) with the goal of improving the mechanical and biological properties...

The results of a cDNA  array revealed that protocadherin gamma subfamily A, 9 (PCDHGA9) was significantly decreased in SGC-7901 gastric cancer (GC) cells compared with GES-1 normal gastric cells and was strongly associated with the Wnt/β-catenin and transforming growth factor-β (TGF-β)/Smad2/3 signaling pathway. As a member of the cadherin family, PCDHGA9 functions in both cell-cell adhesion and nuclear signaling. However, its role in tumorigenicity or metastasis has not been reported. In the present study, we found that PCDHGA9 was decreased in GC tissues compared with corresponding normal mucosae and its expression was correlated with the GC TNM stage, the UICC stage, differentiation, relapse, and metastasis (p < 0...

Fatty metamorphosis is an uncommon alteration in uterine leiomyoma (i.e., lipoleiomyoma), and the pathogenetic mechanisms underlying this phenomenon remain poorly understood. Because a conditional deletion of β-catenin, a major transducer of the canonical Wingless/integrated (WNT) pathway, in the developing mouse uterus can induce adipogenesis in the myometrium, it is hypothesized that inhibition of the WNT/β-catenin signaling may be also involved in the development of fat cells within uterine leiomyoma. In the current study, which was performed to address this point, intracytoplasmic lipid droplets were detectable in cultured human leiomyoma cells by treatment with a potent tankyrase inhibitor, XAV939, which antagonizes β-catenin, in a serum-starved culture medium without additional adipogenesis-inducing agents or supplements, and showed increasing accumulation in a time-dependent manner...

The notion that androgens and androgen receptor (AR) signaling are the hallmarks of prostate cancer oncogenesis and disease progression is generally well accepted. What is more poorly understood is the role of AR signaling in other human malignancies. This special issue of Cancers initially reviews the role of AR in advanced prostate cancer, and then explores the potential importance of AR signaling in other epithelial malignancies. The first few articles focus on the use of novel AR-targeting therapies in castration-resistant prostate cancer and the mechanisms of resistance to novel antiandrogens, and they also outline the interaction between AR and other cellular pathways, including PI3 kinase signaling, transcriptional regulation, angiogenesis, stromal factors, Wnt signaling, and epigenetic regulation in prostate cancer...

Idiopathic pulmonary fibrosis (IPF) is characterized by the expansion of the myofibroblasts population, excessive extracellular matrix accumulation, and destruction of the lung parenchyma. The R-spondins family (RSPO) comprises a group of proteins essential for development. From them, RSPO2 is expressed primarily in the lungs and its mutations cause severe defects in the respiratory tract. Interestingly, RSPO2 participates in the canonical WNT pathway, a critical route in the pathogenesis of IPF. Thus, the aim of this study was to examine the expression and putative role of RSPO2 in this disease...

WNT5A, a representative ligand of activating several non-canonical Wnt signal pathways, plays significant roles in oncogenesis and tumor inhibition. It has been shown that the non-receptor tyrosine kinase SRC is required for WNT5A-induced invasion of osteosarcoma cells. However, the precise molecular mechanism underlying WNT5A/SRC-mediated osteosarcoma cells invasion remains poorly defined. The study was designed to explore the role of ERK1/2 in WNT5A/SRC-induced osteosarcoma cells invasion and the downstream target of the SRC/ERK1/2 signalings...

The switch from fetal to adult hematopoietic stem/progenitor cells (HSPCs) is associated with profound changes in several genetic programs. Although HSPC ageing corresponds to alterations in Wnt signaling, relatively little is known about the relative roles of different Wnt signaling pathways in HSPC ontogeny. We hypothesized that proliferating fetal HSPCs would be more dependent on canonical β-catenin-dependent Wnt signaling when compared to quiescent adult bone marrow HSPCs. We have compared here Wnt signaling activities in murine fetal and adult HSPCs and demonstrate a shift from Wnt/β-catenin-dependent signaling in fetal liver HSPCs to more predominantly noncanonical Wnt/polarity signaling in adult HSPCs...

Tumor-associated Mφs display a plastic phenotype that is regulated by the local tumor milieu. Gene expression analysis and functional characterization of Mφs exposed in vitro to individual cytokines aids to delineate the cross-talk between defined cytokines shaping the complex Mφ phenotype. Human monocyte-derived Mφs can be differentiated in vitro with the T helper cell type 2 response cytokines IL-4 and IL-13 or the immunosuppressive IL-10. Notably, only the latter subset undergoes apoptosis when treated with the CSF 1 receptor (CSF1R) blocking antibody emactuzumab...

Gastric cancer, due to its high incidence rate, is the second leading cause of cancer-related mortality worldwide. Chemotherapy is an important component of the multimodal treatment for gastric cancer; however, a significant impediment to successful treatment is multidrug resistance (MDR) in patients with gastric cancer. In the present study, the protein profiles of the MDR cell line, SGC7901/DDP, and its parental cell line, SGC7901, were comparatively analyzed through an iTRAQ-based quantitative proteomics technique...

Long non-coding RNA (Lnc)TCF7 is a novel lncRNA that is involved in tumorigenesis. Previous studies have revealed that lncTCF7 serves an essential role in maintaining cancer stem cell self-renewal; however, the functions of lncTCF7 in colorectal cancer (CRC) remain unknown. Therefore, the present study aimed to investigate the role of lncTCF7 in CRC. LncTCF7 was upregulated in 52/58 CRC tissues, and its expression correlated with tumor size, lymph metastasis and tumor-node-metastasis stage in CRC. Knocking down lncTCF7 in colon cancer cell lines decreased cell proliferation, migration and invasion, while lncTCF7 overexpression showed opposite changes...

The present study aimed at identifying novel molecular cancer drug targets and biomarkers by analyzing the gene expression profiles of high-grade prostate cancer (PC), using a cDNA microarray combined with laser microbeam microdissection. A number of genes were identified that were transactivated in high-grade PC. First, a novel molecular target and diagnostic biomarker, shisa family member 2 (SHISA2), was identified as an overexpressed gene in high-grade PC cells. The reverse transcription-semi-quantitative polymerase chain reaction and immunohistochemical analysis validated the overexpression of SHISA2 (295 amino acids in length), specifically in high-grade PC cells with Gleason scores of between 8 and 10, relative to normal prostate epithelium...

Small cell lung cancer (SCLC) is the most aggressive type of lung cancer due to a fast tumor doubling time and early hematogenous spread. Advances in the treatment of non-small cell lung cancer using targeted therapies having been made, but no targeted drugs for SCLC have been approved. The Wnt signaling pathway is associated with tumor progression and metastasis; therefore, the inhibition of Wnt/β-catenin signaling is a strategy for anticancer drugs. Tankyrase 1 (TNKS1) is overexpressed in a number of types of cancer and XAV939 is a small molecule inhibitor of TNKS1 which may inhibit tumor growth...
