RNA-seq Analysis of Transcriptomes in β-Gal-overexpressing, NIK-overexpressing, and NIK(KA)-overexpressing αTC1-6 cells

ABSTRACT: Purpose: The goal of this study is to determine the molecular mechanisms involved in the NIK regulation of α cell function. Methods: mRNA profiles of β-Gal control, NIK, and NIK(KA) overexpressed αTC1-6 cells were generated by deep sequencing using an Illumina Hiseq platform. Paired-end clean reads were aligned to the mouse reference genome(Ensemble_GRCm38.89) with TopHat (version 2.0.12), and the aligned reads were used to quantify mRNA expression by using HTSeq-count (version 0.6.1). Conclusion: Our study represents the first detailed analysis of NIK-overexpressing aTC1-6 cell transcriptomes, generated by RNA-seq technology. Our results show that 328 genes were upregulated and 48 genes were downregulated following NIK overexpression. GO analysis indicated that the upregulated genes were primarily related to the immune response. KEGG pathway enrichment analysis showed that immune signaling pathways, including the TNF, NF-κB, and chemokine signaling pathways, were significantly activated by NIK overexpression in aTC1-6 cells, while genes related to metabolism-associated signal pathways were significantly decreased. NIK(KA), the dominant-negative mutant of NIK, does not affect gene expression in aTC1-6 cells.

RNA-seq analysis of mRNA profiles in β-Gal-overexpressing, NIK-overexpressing, and NIK(KA)-overexpressing INS-1 832/13 cells

Project description:Purpose: The goal of this study is to investigate how NIK regulates islet β-cell function. Methods: mRNA profiles of β-Gal-overexpressing, NIK-overexpressing, and NIK(KA)-overexpressing INS-1 832/13 cells were generated by deep sequencing using an Illumina Hiseq platform. Paired-end clean reads were aligned to the rat reference genome (ftp://ftp.ensembl.org/pub/release-90/fasta/rattus_norvegicus/dna/) with TopHat (version 2.0.12), and the aligned reads were used to quantify mRNA expression by using HTSeq-count (version 0.6.1). Conclusion: Our study represents the first detailed analysis of mRNA profiles in NIK-overexpressing and NIK(KA)-overexpressing INS-1 832/13 cells, generated by RNA-seq technology. Our results show that 471 genes were upregulated and 249 genes were downregulated following NIK overexpression. GO analysis indicated that the upregulated genes were primarily related to the immune response. KEGG pathway enrichment analysis showed that immune signaling pathways, including the TNF, NF-κB, antigen processing and presentation signaling pathways, were significantly activated by NIK overexpression in INS-1 832/13 cells, whereas genes related to insulin secretion and regulation of secretion were significantly decreased. NIK(KA), the dominant-negative mutant of NIK, does not induce the expression of genes related to immune response in INS-1 832/13 cells.

RNA-seq Analysis of mRNA profiles in β-Gal-overexpressing, and HuR-overexpressing primary hepatocytes

Project description:Purpose: The goal of this study is to investigate how HuR regulates hepatocyte death. Methods: mRNA profiles of β-Gal-overexpressing, and HuR-overexpressing primary hepatocytes were generated by deep sequencing using an Illumina HiseqX platform. Paired-end clean reads were aligned to the mouse reference genome(Ensemble_GRCm38.83) with TopHat (version 2.0.12), and the aligned reads were used to quantify mRNA expression by using HTSeq-count (version 0.6.1). Conclusion: Our study represents the first detailed analysis of mRNA profiles in HuR-overexpressing primary hepatocytes, generated by RNA-seq technology. Our results show that 258 genes were upregulated and 357 genes were downregulated following HuR overexpression. GO analysis indicated that the upregulated genes were primarily related to cell death, death, apoptotic process, programmed cell death and intrinsic apoptotic signaling pathway. These data indicate that upregulation of HuR leads to hepatocyte death.

NIK expression stimulated G6PD phosphorylation

Project description:Our findings establish NIK as a pivotal regulator of T cell metabolism in anti-tumor immunity and highlight a posttranslational mechanism of metabolic regulation involving the G6PD-NADPH redox system. CoIP assays revealed a strong physical interaction between NIK and G6PD in both T cells and transiently transfected 293 cells, suggesting G6PD to be a direct target of NIK. Using a phosphoprotein gel analysis approach, we demonstrated that NIK expression stimulated G6PD phosphorylation. To further study the mechanism, we performed mass spectrometry identify phosphorylation sites of G6PD stimulated by NIK

RNA-seq Analysis of mRNA profiles in Purβ-overexpressing and Purβ-knocking down hepatocytes

Project description:Purpose: The goal of this study is to investigate how Purβ regulates hepatic glucose production in primary hepatocytes. Methods: mRNA profiles of Purβ-overexpressing, and Purβ-knocking down hepatocytes were generated by deep sequencing using an Illumina NovaSeq 6000 platform. Paired-end clean reads were aligned to the mouse reference genome(Ensemble_GRCm38.96) with TopHat (version 2.0.12), and the aligned reads were used to quantify mRNA expression by using HTSeq-count (version 0.6.1). Conclusion: Our study represents the first detailed analysis of mRNA profiles in Purβ-overexpressing, and Purβ-knocking down hepatocytes, generated by RNA-seq technology. Our results identified Adcy6 was a target of Purβ. RNA-seq analysis showed that Purβ overexpression increased Adcy6 expression, whereas Purβ knockdown decreased Adcy6 expression.

Investigating the effect of NIK SMI1, a small molecule inhibitor of NIK, on TWEAK-stimulated Mouse renal proximal tubule-interstitial epithelial cells (RPTEC)

Project description:Systemic lupus erythematosus (SLE) is often considered a disease driven by autoreactive B cells and anti-nuclear antibodies. However, therapeutic targeting of B cells, for example through BAFF blockade, has been only partially effective in SLE. NF-κB Inducing Kinase (NIK) mediates non-canonical NF-κB signaling downstream of disease relevant TNF family members, such as BAFF, TWEAK, CD40, and OX40. We hypothesized that NIK inhibition might be more efficacious than BAFF blockade in lupus, and therefore generated highly selective and potent small molecule inhibitors (SMI) of NIK to test this hypothesis. RNASeq was used to investigate the effects of one of these SMIs of NIK, NIK SMI1, on TWEAK-stimulated Mouse renal proximal tubule-interstitial epithelial cells (RPTEC).
