Description
Acromegaly is a pathological condition due to excess growth hormone (GH) secretion. Acromegaly patients exhibit a deterioration of health and many associated complications, such as cardiovascular issues, arthritis, kidney diseases, muscular weakness, and colon cancer. Since these complications are generalized throughout the body, we investigated the effect of GH excess on cellular integrity. Here, we established stable acromegaly model zebrafish lines that overexpress tilapia GH and the red fluorescence protein (RFP) reporter gene for tracking GH gene expression throughout generations, and performed RNA-Seq data analysis from different organs. Intriguingly, heatmap and Expression2Kinases (X2K) analysis revealed the enrichment of DNA damage markers in various organs. Moreover, H2A.X immunostaining analysis in acromegaly zebrafish larvae and the adult acromegaly model brain and muscle showed a robust increase in the number of DNA-damaged cells. Using Gene Set Enrichment Analysis (GSEA), we found that the acromegaly zebrafish model had impaired DNA repair pathways in the liver, such as double-strand break (DSB), homologous recombination repair (HRR), non-homologous end joining (NHEJ), nucleotide excision repair (NER), and translesion synthesis (TLS). Interestingly, the impairment of DNA repair was even more prominent in acromegaly model than in aged zebrafish (three years old). Thus, our study demonstrates that affection of cellular integrity is characteristic of acromegaly Overall design: Total mRNA obtained from 1-years old acromegaly zebrafish model muscle, brain, kidney, liver and 3-day old larvae compared to wild-type (WT) zebrafish were generated by deep sequencing using Illumina.

Description
Transcriptome analysis of total RNA samples from HEK293-PIGS-KO and HEK293-PIGS-UBE2J1-DKO cells. To check whether KO of UBE2J1 upregulates genes of GPI biosthesis pathway, we used microarrays to analyze gene expression change by KO of UBE2J1 and comfirmed that known GPI pathway genes are not changed by ERAD-deficiency.

Description
In development, embryonic ectoderm differentiates into several lineages including neuroectoderm and surface ectoderm, through the mechanism largely unclear. Here we report that OVOL2 is required for the transcriptional program of corneal epithelium cell(CEC)s, a derivative of surface ectoderm, and it might regulates the differential transcriptional programs between the two lineages. By a functional screening, we identified transcription factors (TFs) maintaining human CECs. OVOL2 was necessary to maintain the transcriptional program in CECs, particularly through repressing expression of mesenchymal genes. OVOL2 combined with several TFs were able to activate the transcriptional program of CECs in fibroblasts, accompanied by induction of chromatin landscape. Moreover, our analysis revealed that neuroectoderm derivatives express some of mesenchymal genes. In fact, OVOL2 alone was able to induce the transcriptional program of CECs in neural progenitor cells (NPCs) through repression of mesenchymal genes as well as activation of epithelial genes. Our data suggest that the difference between the transcriptional programs of surface ectoderm-derivatives and neuroectoderm-derivatives is regulated in part by the reciprocally-repressive mechanism between epithelial and mesenchymal genes that is seen in epithelial-to-mesenchymal transition.

Description
Alveolar macrophages (AMs) of Bach2 KO mice show multiple alternations in their functions including lipid metabolism. We aimed to clarify the mechanism whereby deficiency of Bach2 impairs the function of AMs and ruins the homeostasis of lungs. Now we report that some cytokines produced from Bach2-deficient T cells alter the character of AMs and expression of Bach2 is necessary for AMs to maintain the function of lipid metabolism. Overall design: mRNA profiling of AMs from 16-week old control mice, Bach2-floxed CD4cre mice, WT mice and Bach2 germline KO mice were examined by deep sequencing using HiSeq2500. Please note that two macrophage populations observed in Bach2-floxed/CD4-cre cKO mice were analyzed; One with normal surface marker phenotype that was the same as control mice (normal). The other with aberrant surface marker phenotype compared with control mice (abnormal).
