  • Hepatitis C Virus As a Unique Human Model Disease to Define
    viruses Review Hepatitis C Virus as a Unique Human Model Disease to Define Differences in the Transcriptional Landscape of T Cells in Acute versus Chronic Infection David Wolski and Georg M. Lauer * Liver Center at the Gastrointestinal Unit, Department of Medicine, Massachusetts General Hospital and Harvard Medical School, Boston, MA 02114, USA * Correspondence: [email protected]; Tel.: +1-617-724-7515 Received: 27 June 2019; Accepted: 23 July 2019; Published: 26 July 2019 Abstract: The hepatitis C virus is unique among chronic viral infections in that an acute outcome with complete viral elimination is observed in a minority of infected patients. This unique feature allows direct comparison of successful immune responses with those that fail in the setting of the same human infection. Here we review how this scenario can be used to achieve better understanding of transcriptional regulation of T-cell differentiation. Specifically, we discuss results from a study comparing transcriptional profiles of hepatitis C virus (HCV)-specific CD8 T-cells during early HCV infection between patients that do and do not control and eliminate HCV. Identification of early gene expression differences in key T-cell differentiation molecules as well as clearly distinct transcriptional networks related to cell metabolism and nucleosomal regulation reveal novel insights into the development of exhausted and memory T-cells. With additional transcriptional studies of HCV-specific CD4 and CD8 T-cells in different stages of infection currently underway, we expect HCV infection to become a valuable model disease to study human immunity to viruses. Keywords: viral hepatitis; hepatitis C virus; T cells; transcriptional regulation; transcription factors; metabolism; nucleosome 1.

  • Development and Validation of a Novel Immune-Related Prognostic Model
    Wang et al. J Transl Med (2020) 18:67 https://doi.org/10.1186/s12967-020-02255-6 Journal of Translational Medicine RESEARCH Open Access Development and validation of a novel immune-related prognostic model in hepatocellular carcinoma Zheng Wang1, Jie Zhu1, Yongjuan Liu3, Changhong Liu2, Wenqi Wang2, Fengzhe Chen1* and Lixian Ma1* Abstract Background: Growing evidence has suggested that immune-related genes play crucial roles in the development and progression of hepatocellular carcinoma (HCC). Nevertheless, the utility of immune-related genes for evaluating the prognosis of HCC patients are still lacking. The study aimed to explore gene signatures and prognostic values of immune-related genes in HCC. Methods: We comprehensively integrated gene expression data acquired from 374 HCC and 50 normal tissues in The Cancer Genome Atlas (TCGA). Diferentially expressed genes (DEGs) analysis and univariate Cox regression analysis were performed to identify DEGs that related to overall survival. An immune prognostic model was constructed using the Lasso and multivariate Cox regression analyses. Furthermore, Cox regression analysis was applied to identify independent prognostic factors in HCC. The correlation analysis between immune-related signature and immune cells infltration were also investigated. Finally, the signature was validated in an external independent dataset. Results: A total of 329 diferentially expressed immune‐related genes were detected. 64 immune‐related genes were identifed to be markedly related to overall survival in HCC patients using univariate Cox regression analysis. Then we established a TF-mediated network for exploring the regulatory mechanisms of these genes. Lasso and multivariate Cox regression analyses were applied to construct the immune-based prognostic model, which consisted of nine immune‐related genes.

Abstract An important mechanism ensuring spatial organization of chromatin structure and genome function in eukaryotic nuclei consists in anchoring of specific heterochromatin regions to nuclear envelope by proteins of inner nuclear membrane (INM) that are able to recognize these regions and simultaneously bind either Lamin A/C or lamin B1. One of these proteins is lamin B receptor (LBR) that binds lamin B1 and tethers heterochromatin to INM in embryonic and undifferentiated cells. It is replaced by lamin A/C with specific lamin A/C binding proteins (especially LEM-domain proteins) at the beginning of cell differentiation.

  • Lamin B1 Is Required for Mature Neuron-Specific Gene Expression
    ARTICLE Received 4 Jul 2016 | Accepted 28 Feb 2017 | Published 20 Apr 2017 DOI: 10.1038/ncomms15098 OPEN Lamin B1 is required for mature neuron-specific gene expression during olfactory sensory neuron differentiation Crystal M. Gigante1,2, Michele Dibattista3,4, Frederick N. Dong1, Xiaobin Zheng2, Sibiao Yue2, Stephen G. Young5, Johannes Reisert3, Yixian Zheng2 & Haiqing Zhao1 B-type lamins are major constituents of the nuclear lamina in all metazoan cells, yet have specific roles in the development of certain cell types. Although they are speculated to regulate gene expression in developmental contexts, a direct link between B-type lamins and developmental gene expression in an in vivo system is currently lacking. Here, we identify lamin B1 as a key regulator of gene expression required for the formation of functional olfactory sensory neurons. By using targeted knockout in olfactory epithelial stem cells in adult mice, we show that lamin B1 deficient neurons exhibit attenuated response to odour stimulation. This deficit can be explained by decreased expression of genes involved in mature neuron function, along with increased expression of genes atypical of the olfactory lineage. These results support that the broadly expressed lamin B1 regulates expression of a subset of genes involved in the differentiation of a specific cell type. 1 Department of Biology, The Johns Hopkins University, Baltimore, Maryland 21218, USA. 2 Department of Embryology, Carnegie Institution for Science, Baltimore, Maryland 21218, USA. 3 Monell Chemical Senses Center, Philadelphia, Pennsylvania 19104, USA. 4 Department of Basic Medical Sciences, Neuroscience and Sensory Organs, University of Bari ‘A.
