The genetic basis of body shape and coloration patterns on caterpillars is often assumed to be regulated separately, but it is possible that common molecules affect both types of trait simultaneously. Here we examine the genetic basis of a spontaneous cuticle defect in silkworm, where larvae exhibit a bamboo-like body shape and also decreased pigmentation. We performed linkage mapping and mutation screening to determine the gene product that affects body shape and coloration simultaneously. In these mutant larvae we identified a null mutation in BmorCPH24, a gene encoding a cuticular protein with low complexity sequence...

Neural crest (NC) cells are a migratory, multipotent population giving rise to numerous lineages in the embryo. Their plasticity renders attractive their use in tissue engineering-based therapies but further knowledge on their in vivo behaviour is required before clinical transfer may be envisioned. We here describe isolation and characterization of a new mouse ES line derived from Wnt1-CRE-R26 RosaTomatoTdv blastocyst and show that it displays the characteristics of typical ES cells. Furthermore, these cells can be efficiently directed towards a NC stem cell-like phenotype as attested by concomitant expression of NC marker genes and Tomato fluorescence...

Plasticizer di(2-ethylhexyl)phthalate (DEHP) can leach from medical devices such as blood storage bags and the tubing. Recently, epidemiological studies showed that phthalate metabolites levels in the urine are associated with low bone mineral density (BMD) in older women. The detailed effect and mechanism of DEHP on osteoblastogenesis and adipogenesis and bone loss remain to be clarified. Here, we investigated the effect and mechanism of DEHP and its active metabolite mono(2 -ethylhexyl)phthalate (MEHP) on osteoblastogenesis and adipogenesis...

Bone marrow-derived mesenchymal stem cells (BM-MSCs), which are characterized by multipotency and self-renewal, are responsible for tissue regeneration and repair. We have previously reported in adipose tissue-derived MSCs that only Wnt5a is enhanced at neurogenic differentiation, and the mechanism of differentiation is dependent on the Wnt5a/JNK pathway; however, the role of Wnt/MAPK pathway is yet to be investigated in neurogenic differentiation in BM-MSCs. We compared the transcriptional expression of Wnt in neurogenic induced-hBM-MSCs (NI-hBM-MSCs) with that in primary hBM-MSCs, using RT-PCR, qPCR, and western blotting...

Glioblastoma is the most common and aggressive primary brain tumor and has a high mortality in humans. However, mechanisms and factors involved in the progression of glioblastoma remain elusive. WISP1 (WNT1 inducible signaling pathway protein 1), has been suggested to be a critical regulator of cancer development. The aim of this study was to investigate the role of WISP1 in regulating the progression of glioblastoma. Clinicopathological characteristics of glioblastoma were assessed, and higher levels of WISP1 were positively associated with advanced clinical stage and a poor prognosis...

Wnt/β-catenin signaling is instrumental for the development of mammary gland and the properties of mammary stem cells (MaSCs). The Wnt signaling downstream effectors that engage in regulating MaSCs have not been extensively studied. Here, we report that Neuropilin-1 (Nrp1) expression is induced by Wnt/β-catenin signaling in MaSCs, and its function is critical for the activity of MaSCs. Nrp1 is particularly expressed in MaSCs that are marked by the expression of Protein C Receptor (Procr). Knockdown of Nrp1 by shRNA diminishes MaSCs' in vitro colony formation and in vivo mammary gland reconstitution ability...

The auditory system contains a diverse array of interconnected anatomical structures that mediate the perception of sound. The cochlear nucleus of the hindbrain serves as the initial site of convergence for auditory stimuli, while the inferior colliculus of the midbrain serves as an integration and relay station for all ascending auditory information. We used Genetic Inducible Fate Mapping (GIFM) to determine how the timing of Wnt1 expression is related to the competency states of auditory neuron progenitors...

The variation of macrophage functions suggests the involvement of multiple signaling pathways in fine tuning their differentiation. Macrophages that originate from monocytes in the blood migrate to tissue in response to homeostatic or "danger" signals and undergo substantial morphological and functional modifications to meet the needs of the dominant signals in the microenvironment. Wnts are secreted glycoproteins that play a significant role in organ and cell differentiation, yet their impact on monocyte differentiation is not clear...

BACKGROUND: Exploring the molecular mechanisms underlying directed differentiation is helpful in the development of clinical applications of mesenchymal stem cells (MSCs). Our previous study on dental tissue-derived MSCs demonstrated that secreted frizzled-related protein 2 (SFRP2), a Wnt inhibitor, could enhance osteogenic differentiation in stem cells from the apical papilla (SCAPs). However, how SFRP2 promotes osteogenic differentiation of dental tissue-derived MSCs remains unclear...

Hedgehog signaling plays crucial roles in the development of calvarial bone, relying on the activation of Gli transcription factors. However, the molecular mechanism of the role of regulated Gli protein level in osteogenic specification of mesenchyme still remains elusive. Here, we show by conditionally inactivating Suppressor of Fused (Sufu), a critical repressor of Hedgehog signaling, in Wnt1-Cre mediated cranial neural crest (CNC), or Dermo1-Cre mediated mesodermal lineages, that Sufu restraint of Hedgehog activity level is critical for differentiation of pre-osteogenic mesenchyme...

BACKGROUND: Hypoplastic left heart syndrome (HLHS) covers a spectrum of rare congenital anomalies characterised by a non-apex forming left ventricle and stenosis/atresia of the mitral and aortic valves. Despite many studies, the causes of HLHS remain unclear and there are conflicting views regarding the role of flow, valvar or myocardial abnormalities in its pathogenesis, all of which were proposed prior to the description of the second heart field. Our aim was to re-evaluate the patterns of malformation in HLHS in relation to recognised cardiac progenitor populations, with a view to providing aetiologically useful sub-groupings for genomic studies...

In response to injury, epithelial cells migrate and proliferate to cover denuded mucosal surfaces and repair the barrier defect. This process is orchestrated by dynamic crosstalk between immune cells and the epithelium; however, the mechanisms involved remain incompletely understood. Here, we report that IL-10 was rapidly induced following intestinal mucosal injury and was required for optimal intestinal mucosal wound closure. Conditional deletion of IL-10 specifically in CD11c-expressing cells in vivo implicated macrophages as a critical innate immune contributor to IL-10-induced wound closure...

It has been suggested that age-related neurodegeneration might be associated with neuropeptide Y (NPY); sirtuin1 (SIRT1) and forkhead box transcription factors O subfamily (FOXOs) pathways. Melatonin, a hormone mainly secreted by the pineal gland, is another anti-aging agent associated with the SIRT1-FOXOs pathway. This study aimed to compare the effects of melatonin (Mel) and caloric restriction (CR) on the expression of Sirt1, FoxO1, FoxO3a and FOXOs target genes in the aging mouse hippocampus. Neuropeptide Y-knockout (NpyKO) and wild-type (WT) male mice aged 19 months were previously treated either with food ad libitum or CR for 16 months...

In this study, we reported that long non-coding RNA (lncRNA) CCAT1 was upregulated in epithelial ovarian cancer (EOC) tissues, and was associated with FIGO stage, histological grade, lymph node metastasis and poor survival of EOC patients. Multivariate Cox regression analysis showed that CCAT1 was an independent prognostic indicator. While CCAT1 downregulation inhibited EOC cell epithelial-mesenchymal transition (EMT), migration and invasion, CCAT1 upregulation promoted EOC cell EMT, migration and invasion...

Dorsal root ganglion (DRG) neurons receive peripheral somatosensory information and send orderly projections to second-order relay nuclei in the spinal cord and in the brainstem. Atypical cadherin Celsr3 is known to play a critical role in wiring of several central and peripheral axons. Although Celsr3 mRNA is heavily expressed in DRG neurons, its role in the development of somatosensory projections remains unexplored. Here we assessed the role of Celsr3 in DRG using conditional gene inactivation in crosses with Wnt1-Cre mice...

Extrahepatic cholangiocarcinoma (ECC) is a deadly disease that often responds poorly to conventional chemotherapy or radiotherapy. Long noncoding RNAs (lncRNAs) play important roles in human cancers, including ECC, and recent studies indicated that the lncRNA prostate cancer-associated transcript 1 (non-protein coding) (PCAT1) is involved in multiple cancers. However, the role of PCAT1 in ECC is unclear. Previously, we showed that PCAT1 is up-regulated in both ECC tissue samples and cell lines. Here, we showed that downregulation of PCAT1 following transfection with silencing RNA reduced ECC cell growth and increased cell apoptosis...

BACKGROUND: Evidence indicates that wingless-type MMTV integration site family, member 1 (WNT1)-inducible signaling pathway protein 2 (WISP2) may play an important role in the development of gastric cancer (GC) by regulating the WNT/β-catenin signaling pathway. In the present study, we investigated whether there is correlation between WISP2 and β-catenin proteins, and their association with clinicopathological features in GC. MATERIALS AND METHODS: Immunohistochemical staining was carried out on 119 paraffin-embedded gastric cancer tissues and 99 adjacent normal gastric tissues collected from patients with GC at the Beijing Cancer Hospital...

BACKGROUND: Cell-free RNA in amniotic fluid supernatant reflects developmental changes in gene expression in the living fetus, which includes genes that are specific to the central nervous system. Although it has been previously shown that central nervous system-specific transcripts are present in amniotic fluid supernatant, it is not known whether changes in the amniotic fluid supernatant transcriptome reflect the specific pathophysiologic condition of fetal central nervous system disorders...
