Abstract
Cleft palate (CP) is one of the most common congenital diseases, and is accompanied by a complicated etiology. Medical exposure in women is among one of the reasons leading to CP. Recently, it has been reported that microRNA (miRNA) plays a crucial role in palate formation and the disruption of miRNA that influence the development of CP. Although association with pharmaceuticals and miRNAs were suggested, it has remained largely unknow. The aim of the current investigation is to elucidate upon the miRNA associated with the inhibition of phenobarbital (PB)-induced cell proliferation in human embryonic palatal mesenchymal (HEPM) cells. We showed that PB inhibited HEPM cell viability in a dose-dependent manner. We demonstrated that PB treatment suppressed cyclin-D1 expression in HEPM cells. Furthermore, PB upregulated let-7c-5p expression and downregulated the expression of two downstream genes (BACH1 and PAX3). Finally, we demonstrated that the let-7c-5p inhibitor alleviated PB-induced inhibition of cell proliferation and altered BACH1 and PAX3 expression levels. These results suggest that PB suppresses cell viability by modulating let-7c-5p expression.

Abstract
Cleft palate (CP) is one of the most common birth defects and is caused by a combination of genetic and/or environmental factors. Environmental factors such as pharmaceutical exposure in pregnant women are known to induce CP. Recently, microRNA (miRNA) was found to be affected by environmental factors. The aim of the present study was to investigate the involvement of miRNA against phenytoin (PHE)-induced inhibition of proliferation in human embryonic palatal mesenchymal (HEPM) cells. We demonstrated that PHE inhibited HEPM cell proliferation in a dose-dependent manner. We found that treatment with PHE downregulated cyclin-D1 and cyclin-E expressions in HEPM cells. Furthermore, PHE increased miR-4680-3p expression and decreased two downstream genes (ERBB2 and JADE1). Importantly, an miR-4680-3p-specific inhibitor restored HEPM cell proliferation and altered expression of ERBB2 and JADE1 in cells treated with PHE. These results suggest that PHE suppresses cell proliferation via modulation of miR-4680-3p expression.

Abstract
Background Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common craniofacial birth defect. Growing evidence has demonstrated the competing endogenous RNA (ceRNA) hypothesis has played a role in the pathogenesis of NSCL/P. Here, we identified the important lncRNAs in NSCL/P and constructed a ceRNA regulatory network to predict their underlying functional mechanism. Methods Total RNA isolated from the peripheral blood samples were analyzed by the Human Clariom D Affymetrix platform and differentially expressed genes (DEGs) were identified. Using the limma package in R software, DEGs in the expression profile of GSE42589 were identified from Gene Expression Omnibus (GEO) database. Co-differentially expressed lncRNAs (co-DElncRNAs) were used to predict the microRNAs that may bind to them. Co-differentially expressed mRNAs (co-DEmRNAs) were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. The hub genes were screened using the cytohubba plug-in in Cytoscape. A ceRNA network was built to investigate the molecular mechanism underlying the etiology of NSCL/P. The expression levels of lncRNAs, miRNAs, and mRNAs in the network were assessed by quantitative real-time polymerase chain reaction (qRT-PCR). Results We found 116 DElncRNAs and 2955 DEmRNAs from the GSE42589 dataset, and 2626 DElncRNAs and 2771 DEmRNAs from the Human Clariom D gene chip. A network of co-DEmRNAs containing 3712 edges and 621 nodes were identified by PPI analysis. A ceRNA regulatory network comprising lncRNA USP17L6P, hsa-miR-449c-5p, and MYC was established. qRT-PCR results revealed significantly lower expression levels of lncRNA USP17L6P and c-Myc in NSCL/P tissues, while the expression level of hsa-miR-449c-5p was higher as compared to control samples (p < 0.05). Conclusion The identified lncRNAs and the established ceRNA regulatory network provide novel insight into the pathogenesis of NSCL/P, therefore hold great promise in NSCL/P management in clinical practice.

Abstract
Cleft palate is the second most common congenital birth defect, and both environmental and genetic factors are involved in the etiology of the disease. However, it remains largely unknown how environmental factors affect palate development. Our previous studies show that several microRNAs (miRs) suppress the expression of genes involved in cleft palate. Here we show that miR-4680-3p plays a crucial role in cleft palate pathogenesis. We found that all-trans retinoic acid (atRA) specifically induces miR-4680-3p in cultured human embryonic palatal mesenchymal (HEPM) cells. Overexpression of miR-4680-3p inhibited cell proliferation in a dose-dependent manner through the suppression of expression of ERBB2 and JADE1, which are known cleft palate-related genes. Importantly, a miR-4680-3p-specific inhibitor normalized cell proliferation and altered expression of ERBB2 and JADE1 in cells treated with atRA. Taken together, our results suggest that upregulation of miR-4680-3p induced by atRA may cause cleft palate through suppression of ERBB2 and JADE1. Thus, miRs may be potential targets for the prevention and diagnosis of cleft palate.

Abstract
Laryngeal carcinoma is the most common type of malignant tumor in the head and neck. Long non-coding RNAs (lncRNAs) serve crucial roles in numerous biological processes. The present study aimed to investigate the role of lncRNA SOX2-OT in laryngeal cancer and to reveal the underlying mechanisms. Reverse transcription-quantitative PCR assays were used to measure the expression levels of SOX2-OT in the laryngeal cell lines. Furthermore, cell proliferation, apoptosis, migration and invasion were assessed by CCK-8, flow cytometry, wound healing and Transwell assays, respectively. Western blot assay was performed to detect the protein expressions. In addition, a dual-luciferase reporter assay was performed to confirm the direct interaction between SOX2-OT and microRNA (miR)-654. The data demonstrated that SOX2-OT level were significantly increased in the laryngeal cell lines. Furthermore, SOX2-OT silencing markedly promoted apoptosis and suppressed the proliferation, migration and invasion of TU-177 cells. A dual-luciferase reporter assay revealed that miR-654 was a direct target of SOX2-OT. Moreover, downregulation of miR-654 could attenuate cell apoptosis and accelerate cell proliferation, migration and invasion in TU-177 cells. In summary, the present study reported that knockdown of SOX2-OT could suppress cell proliferation, migration and invasion, and induce apoptosis in laryngeal cancer by targeting miR-654.

Abstract
VipAlbumin® is a supplement from snakehead fish (Ophiocephalus striatus) which has high content of albumin that is very important to develop new cells. The aims of this study were to know the effect of VipAlbumin® to cell proliferation, expression level of CD4+CD62L+ T cell, regulatory T cell, and B220+ cell, and immunocompetent cell cycle. Cell isolated from spleen of pathogen free mice were cultured in RPMI 1640 with 10% FBS, 1% Pen/Strep 10×, 2-Mercaptoetanol, anti-CD3 and LPS. The concentrations of VipAlbumin
® used were 0 µg/ml; 0.33 µg/ml; 33.3 µg/ml; and 3333.3 µg/ml. The cell was incubated in CO2 5% incubator 37°C for 3 days for cell cycle and 5 days for proliferation analysis and cell expression. FACS analysis was done to know cell proliferation profile, status of cell, and cell cycle. Concentration 33.3 µg/ml and 3333.3 µg/ml significantly can increase cell proliferation and induce cell enter G2/M phase (p < 0.05) compared to control. VipAlbumin can significantly increase the relative number of CD4+CD62L+ T cell, regulatory T cell, and B220+ cell (p < 0.05) compared to control. This study gives scientific evidence that VipAlbumin can be used as an immunostimulant which accelerates immunocompetent cells growth.

Abstract
Store-operated calcium entry (SOCE) signaling is involved in cancer progression. Stromal interaction molecule 1 (STIM1) triggers store-operated calcium channels to induce SOCE. Transforming growth factor-β (TGF-β) influences a wide range of cellular behaviors, including cell proliferation. However, little is known about the relationship between calcium signaling and TGF-β signaling in cancer cell proliferation. Here, we found that TGF-β induced cell cycle arrest at the G0/G1 phase and suppressed cell proliferation in MDA-MB-231 and MCF-7 breast cancer cells. These effects were impaired by extracellular Ca2+ chelator EGTA or SOCE specific inhibitor SKF96365 in MDA-MB-231 cells. Treating MDA-MB-231 cells with TGF-β for 24 and 48 h markedly decreased STIM1 expression and thapsigargin-induced SOCE. A transcriptional inhibitor of STIM1, Wilm's tumor suppressor 1 (WT1), was upregulated in TGF-β-treated MDA-MB-231 cells, and knockdown of WT1 expression partially restored the TGF-β-induced downregulation of STIM1. Stably overexpressing STIM1 in MDA-MB-231 cells restored the TGF-β-induced effects. The p21 mRNA level increased in SKF96365- or TGF-β-treated MDA-MB-231 cells, whereas that for cyclin E1 decreased. Our findings demonstrate for the first time that STIM1 and SOCE are involved in the TGF-β-induced suppression of cell proliferation. Furthermore, our studies also provide a new approach to inhibit breast cancer cell proliferation with small molecules targeting STIM1 and SOCE.

Dhcr7 Regulates Palatal Shelf Fusion through Regulation of Shh and Bmp2 Expression. BIOMED RESEARCH INTERNATIONAL 2016; 2016:7532714.

Abstract
The aim of this study was to investigate the effect of the 7-dehydrocholesterol reductase (Dhcr7) gene and identify signaling pathways involved in regulation of embryonic palatogenesis. The expression of Dhcr7 and its protein product were examined during murine normal embryonic palatogenesis via a reverse transcription polymerase chain reaction (RT-PCR) and Western blot (WB). RNA interference (RNAi) technology was used to inhibit Dhcr7 expression in a palatal shelf culture in vitro. The effects of Dhcr7 on palatogenesis and palatal fusion were examined by scanning electron microscopy (SEM). The expression changes of Dhcr7, Sonic Hedgehog (Shh), and bone morphogenetic protein-2 (Bmp2) were measured by RT-PCR and WB after Dhcr7 gene silencing and the addition of exogenous cholesterol. The results showed that the palatal shelf failed to complete normal development and fusion when Dhcr7 expression was inhibited. The inhibitory effect study of RNAi on the development of the palatal shelf supported that cholesterol supplementation did not alter the silencing of Dhcr7. Shh and Bmp2 expressions were reduced after Dhcr7 gene silencing, and administration of exogenous cholesterol did not affect Dhcr7 expression; however Shh and Bmp2 expressions increased. We conclude that Dhcr7 plays a role in growth of the palatal shelf and can regulate palatogenesis through alterations in the levels of Shh and Bmp2.

Abstract
The Sonic Hedgehog (Shh) signaling pathway is commonly activated in gastrointestinal cancer. However, our understanding of the Shh pathway in gastric cancer remains limited. Here we examined the effects of cyclopamine, a specific inhibitor of the Shh signaling pathway, on cell growth and proliferation in gastric primary cancer cells GAM-016 and the MKN-45 cell line. The results showed that the Shh signaling molecules SHH, PTCH, SMO, GLI1, and GLI2 were intact and activated in both types of cells. Furthermore, we observed that cyclopamine inhibited gastric cancer cell proliferation through cell cycle arrest and apoptosis. An in vivo study using NOD/SCID mouse xenografts demonstrated that cyclopamine significantly prevented tumor growth and development. Our study indicated that Shh signaling pathway could promote gastric cancer cell proliferation and tumor development, and blocking this pathway may be a potential strategy in gastric cancer treatment.

Abstract
Many metabolites with novel structures and biological activities have been isolated from the mangrove fungi in the South China Sea, such as anthracenediones, xyloketals, sesquiterpenoids, chromones, lactones, coumarins and isocoumarin derivatives, xanthones, and peroxides. Some compounds have anticancer, antibacterial, antifungal and antiviral properties, but the biosynthesis of these compounds is still limited. This review summarizes the advances in the study of secondary metabolites from the mangrove-derived fungi in the South China Sea, and their biological activities reported between 2008 and mid-2013.

Abstract
The upper lip and primary palate form an essential separation between the brain, nasal structures and the oral cavity. Surprisingly little is known about the development of these structures, despite the fact that abnormalities can result in various forms of orofacial clefts. We have uncovered that retinoic acid is a critical regulator of upper lip and primary palate development in Xenopus laevis. Retinoic acid synthesis enzyme, RALDH2, and retinoic acid receptor gamma (RARγ) are expressed in complementary and partially overlapping regions of the orofacial prominences that fate mapping revealed contribute to the upper lip and primary palate. Decreased RALDH2 and RARγ result in a median cleft in the upper lip and primary palate. To further understand how retinoic acid regulates upper lip and palate morphogenesis we searched for genes downregulated in response to RARγ inhibition in orofacial tissue, and uncovered homeobox genes lhx8 and msx2. These genes are both expressed in overlapping domains with RARγ, and together their loss of function also results in a median cleft in the upper lip and primary palate. Inhibition of RARγ and decreased Lhx8/Msx2 function result in decreased cell proliferation and failure of dorsal anterior cartilages to form. These results suggest a model whereby retinoic acid signaling regulates Lhx8 and Msx2, which together direct the tissue growth and differentiation necessary for the upper lip and primary palate morphogenesis. This work has the potential to better understand the complex nature of the upper lip and primary palate development which will lead to important insights into the etiology of human orofacial clefts.

Abstract
Defective bone and cartilage development account for a large number of human birth defects annually. Normal skeletogenesis involves cartilage development in early morphogenesis through a highly coordinated and orchestrated series of events involving commitment and differentiation of mesenchymal cells to chondrocytes followed by a highly programmed process of structural maturation. Recent developmental studies with laboratory model fish demonstrate that exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) results in cartilage and skeletal abnormalities. In this study, we exposed embryonic medaka to TCDD to induce developmental modification(s) of both cartilage and bone formation. Emphasis is placed on cell-rich hyaline cartilage of the hypural plate where both chondrogenesis and osteogenesis are impaired by TCDD exposure. In this model, TCDD exposure results in a concentration-dependent impairment of mesenchymal cell recruitment, chondrocyte cell proliferation, differentiation, and progression to hypertrophy. Gene expression of ColA2, a marker of chondrocyte terminal differentiation in hypural structures, is markedly attenuated consistent with hypural dysmorphogenesis. Assessment of hypural structure using a transgenic medaka expressing mCherry under control of the osterix promoter illustrated significant attenuation in expression of the osteoblast gene marker and lack of formation of a calcified perichondral sheath surrounding hypural anlage. Overall, these studies illustrate that TCDD impacts terminal differentiation and growth of cartilage and bone in axial structures not likely derived from neural crest progenitors in medaka hypurals.

Abstract
In the past, most scientists conducted their inquiries of nature via inductivism, the patient accumulation of "pieces of information" in the pious hope that the sum of the parts would clarify the whole. Increasingly, modern biology employs the tools of bioinformatics and systems biology in attempts to reveal the "big picture." Most successful laboratories engaged in the pursuit of the secrets of embryonic development, particularly those whose research focus is craniofacial development, pursue a middle road where research efforts embrace, rather than abandon, what some have called the "pedestrian" qualities of inductivism, while increasingly employing modern data mining technologies. The secondary palate has provided an excellent paradigm that has enabled examination of a wide variety of developmental processes. Examination of cellular signal transduction, as it directs embryogenesis, has proven exceptionally revealing with regard to clarification of the "facts" of palatal ontogeny-at least the facts as we currently understand them. Herein, we review the most basic fundamentals of orofacial embryology and discuss how functioning of TGFbeta, BMP, Shh, and Wnt signal transduction pathways contributes to palatal morphogenesis. Our current understanding of palate medial edge epithelial differentiation is also examined. We conclude with a discussion of how the rapidly expanding field of epigenetics, particularly regulation of gene expression by miRNAs and DNA methylation, is critical to control of cell and tissue differentiation, and how examination of these epigenetic processes has already begun to provide a better understanding of, and greater appreciation for, the complexities of palatal morphogenesis.

Abstract
Biodiversity is a major resource for identification of new molecules with specific therapeutic activities. To identify such an active resource, high throughput screening (HTS) of the extracts prepared from such diversity are examined on specific functional assays. Based on such HTS studies and bioactivity-based fractionation, we have isolated ergoflavin, a pigment from an endophytic fungus, growing on the leaves of an Indian medicinal plant Mimosops elengi (bakul). We report here the isolation, structure elucidation, and biological properties of this compound, which showed good anti-inflammatory and anticancer activities.

Abstract
PURPOSE To determine if molecular markers typically associated with ultraviolet exposure could be detected in canine ocular hemangiomas (HA) and hemangiosarcomas (HSA). METHODS Paraffin-embedded samples of canine ocular HA (n = 6) and HSA (n = 6) were examined for the presence of p53, p21, p16, cyclin D, PCNA, pAkt, telomerase, and estrogen receptor (ER)-alpha using immunohistochemistry. RESULTS p53 and cyclin D protein were not detected in any of the canine HA or HSA samples. The majority of the HA and HSA were negative for both p21 and telomerase. pAkt immunoreactivity was absent in one HA, one HSA, but was present in five HA and five HSA. All of the HA or HSA samples were strongly positive for p16 and PCNA. ERalpha was expressed in all of the samples examined; there was more intense staining in the HSA samples compared to the HA samples. CONCLUSIONS Results from this study describe the protein expression, via immunohistochemistry, that might be altered in UV exposure in HA and HAS formation. p53 may not play an important role in tumor development; rather, in the tumors examined, expression of cell cycle regulators independent of the p53 pathway appear central in HA and HSA formation and progression. In addition, this study finds that ERalpha may be involved in promoting the invasive behavior associated with HSA.

Abstract
Objectives:The aim of this study was to analyze epigenetic (specifically, DNA methylation) participation in the mechanisms of cleft palate only induced by maternal exposure to all-trans retinoic acid in mice.Design:Cleft palate only was induced in fetuses by maternal exposure to all-trans retinoic acid. Their secondary palates were excised for analysis. Cytosine extension assay and restriction landmark genomic scanning were performed to analyze DNA methylation status. The expression levels of the DNA methyltransferases were examined by real-time reverse transcriptase–polymerase chain reaction.Results:Using cytosine extension assay, on gestation day 14.5, the status of DNA methylation within CpG islands and in global DNA was decreased significantly in all-trans retinoic acid–treated groups compared with the controls (p < .01 and p < .05). In the controls, the status within CpG islands on gestation day 14.5 was significantly increased compared with gestation days 13.5 and 18.5 (p < .01). Using real-time reverse transcriptase–polymerase chain reaction, there was no significant change in the expression of DNA methyltransferases, except on gestation day 18.5. Using restriction landmark genomic scanning on gestation day 18.5, five spots (0.49%) in the controls and one spot (0.1%) in all-trans retinoic acid–treated groups were specifically detected.Conclusions:These results indicate that changes in DNA methylation may play an important role in the manifestation of cleft palate only caused by environmental factors such as maternal exposure to all-trans retinoic acid.
