Oct4 plays a role in 2, 3, 7, 8 - tetrachlorobenzo-p-dioxin (TCDD) inducing cleft palate and inhibiting mesenchymal proliferation. Toxicology 2020; 438:152444. [PMID: 32283119 DOI: 10.1016/j.tox.2020.152444] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 03/17/2020] [Accepted: 03/25/2020] [Indexed: 02/07/2023]
Abstract
As a common birth defect, Cleft palate can be caused by the disturbance during the developmental process of the palatal shelves. The 2,3,7,8-tetrachlorodibenzo- p-dioxin (TCDD) is a well-known environmental teratogenic agent for cleft palate and Aryl hydrocarbon receptor (AhR) pathway can be activated by dioxins. Oct4 as a pluripotent stem cell transcription factor is also involved in the process of embryonic development. The AHR and retinoid receptors have cross-talk at CYP1A1 (cytochrome P450, family 1, subfamily A, polypeptide 1) promoter. There are also bidirectional talk between AhR and Oct4. In this study, we used C57/BL6 N mice and TCDD (64 μg/Kg body weight) to establish a model of fetal cleft palate to observe the effects of dioxin on fetal mesenchymal proliferation and apoptosis, and explore the role of Oct4 in inducing cleft palate. The results showed that dioxin inhibited mesenchymal proliferation and promoted apoptosis. In addition, dioxin inhibited Oct4 expression, and preliminary data suggest that hypermethylation of the Oct4 promoter may be a putative mechanism, suggesting that TCDD might induce cleft palate by inhibiting the proliferation of palatal mesenchymal cells mediated by Oct4.

Retinoic acid exacerbates chlorpyrifos action in ensuing adipogenic differentiation of C3H10T½ cells in a GSK3β dependent pathway. PLoS One 2017; 12:e0173031. [PMID: 28291828 PMCID: PMC5349446 DOI: 10.1371/journal.pone.0173031] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Accepted: 02/14/2017] [Indexed: 01/15/2023] Open
Abstract
The cell differentiation can be exploited as a paradigm to evaluate the effects of noxious chemicals, on human health, either alone or in combinations. In this regard, the effect of a known cell differentiation agent, retinoic acid (RA) was analyzed in the presence of a noxious chemical chlorpyrifos (CPF), an organophosphate (OP), the receptors of which have recently been localized to mesenchymal stem cells (MSCs). The observed imbalance of adipogenic to skeletal differentiation by CPF together with conundrum about adipogenic potential of RA prompted us to delineate their combinatorial effects on C3H10T½MSC-like undifferentiated cells. Based on MTT assay, the cellular viability was retained by CPF at concentrations ranging from 0.01–50μM, beyond which it caused cytotoxicity. These non-toxic concentrations also mildly interfered with adipogenesis of C3H10T½ cells following exposure to adipogenic cocktail. However, upon exposure to RA alone, these MSCs adopted elongated morphology and accumulated lipid vesicles, by day 20, as discerned by phase-contrast and transmission electron microscopy (TEM), in concert with enhanced Oil Red O stained cells. This effect got strongly augmented upon exposure to combination of CPF and RA in a dose-dependent manner. Simultaneous up-regulation in perilipin-1 (PLIN1) and adipsin (ADN) genes, additionally reiterated the adipogenic differentiation. Mechanistically, GSK3β pathway was found to be a major player, whereby inhibiting it with lithium chloride (LiCl) resulted in complete blockage of lipid accumulation, accompanied by complete down regulation of PLIN1 and ADN gene expression. In conclusion, these observations for the first time, lend evidence that exposure of CPF accompanied by RA directs commitment of C3H10T½ cells to adipogenic differentiation through a process involving a crosstalk at GSK3β signaling.

Abstract
The vertebrate inner ear is a complex three-dimensional sensorial structure with auditory and vestibular functions. The molecular patterning of the developing otic epithelium creates various positional identities, consequently leading to the stereotyped specification of each neurosensory and non-sensory element of the membranous labyrinth. The Iroquois (Iro/Irx) genes, clustered in two groups (A: Irx1, Irx2, and Irx4; and B: Irx3, Irx5, and Irx6), encode for transcriptional factors involved directly in numerous patterning processes of embryonic tissues in many phyla. This work presents a detailed study of the expression patterns of these six Irx genes during chick inner ear development, paying particular attention to the axial specification of the otic anlagen. The Irx genes seem to play different roles at different embryonic periods. At the otic vesicle stage (HH18), all the genes of each cluster are expressed identically. Both clusters A and B seem involved in the specification of the lateral and posterior portions of the otic anlagen. Cluster B seems to regulate a larger area than cluster A, including the presumptive territory of the endolymphatic apparatus. Both clusters seem also to be involved in neurogenic events. At stages HH24/25-HH27, combinations of IrxA and IrxB genes participate in the specification of most sensory patches and some non-sensory components of the otic epithelium. At stage HH34, the six Irx genes show divergent patterns of expression, leading to the final specification of the membranous labyrinth, as well as to cell differentiation.

Abstract
Body size is the most important economic trait for animal production and breeding. Several hundreds of loci have been reported to be associated with growth trait and body weight in chickens. The loci are mapped to large genomic regions due to the low density and limited number of genetic markers in previous studies. Herein, we employed comparative population genomics to identify genetic basis underlying the small body size of Yuanbao chicken (a famous ornamental chicken) based on 89 whole genomes. The most significant signal was mapped to the BMP10 gene, whose expression was upregulated in the Yuanbao chicken. Overexpression of BMP10 induced a significant decrease in body length by inhibiting angiogenic vessel development in zebrafish. In addition, three other loci on chromosomes 1, 2, and 24 were also identified to be potentially involved in the development of body size. Our results provide a paradigm shift in identification of novel loci controlling body size variation, availing a fast and efficient strategy. These loci, particularly BMP10, add insights into ongoing research of the evolution of body size under artificial selection and have important implications for future chicken breeding.

PLoS One 2015; 10:e0145700. [PMID: 26697877 PMCID: PMC4689451 DOI: 10.1371/journal.pone.0145700] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2015] [Accepted: 12/06/2015] [Indexed: 12/27/2022] Open
Abstract
OBJECTIVE This study aimed to investigate the methylation status of the promoter region of spalt-like transcription factor 3 (SALL3) and the expression of SALL3 in cervical cancer to explore the function of this gene in cervical cancer carcinogenesis. METHODS The methylation status of SALL3 was detected by methylation-specific PCR, and SALL3 gene expression was assessed by real-time quantitative PCR in the cervical cancer cell lines, SiHa, HeLa and C33A, as well as in cervical cancer tissue samples (n = 23), matched pericarcinomatous tissue samples (n = 23) and normal cervix tissue samples (n = 17). MTT was used to measure the cell viability and proliferation capacity of SiHa and HeLa cells. RESULTS The SALL3 promoter was completely methylated in SiHa cells, unmethylated in C33A cells and partially methylated in HeLa cells. After treatment of SiHa and HeLa cells with 5 μM and 10 μM of 5-Azacytidine (5-Aza), respectively, the methylation level of the SALL3 promoter decreased and observed increase in the degree of unmethylation in a dose-dependent manner. Moreover, the relative expression of SALL3 mRNA increased as the concentration of 5-Aza increased in SiHa (p<0.05) and HeLa (p<0.05) cells. This above-mentioned increase in SALL3 mRNA in SiHa cells was more remarkable than that observed in HeLa cells. Cell proliferation capacity also decreased after administration of 5-Aza to SiHa and HeLa cells (p<0.05). Methylation of the SALL3 promoter was observed in 15 of 23 (65.21%) cervical cancer tissue samples, 15 of 23 (65.21%) matched pericarcinomatous tissue samples and 5 of 17 (29.41%) normal cervical tissue samples (p<0.05). SALL3 mRNA expression was significantly lower in cervical cancer and pericarcinomatous tissues compared with normal cervical tissues (p<0.05). In all cervix tissue samples, HPV infection was positively associated with hypermethylation of the promoter region of SALL3 (p<0.05, r = 0.408), and the expression of SALL3 mRNA in HPV-positive tissues was lower than that in HPV-negative tissues (p<0.05). CONCLUSION The aberrant hypermethylation of SALL3 together with HPV involvement inactivated its function as a tumor suppressor and contributed to carcinogenesis in cervical cancer.
