J Transl Med (2021) 19:372 https://doi.org/10.1186/s12967-021-02979-z Journal of Translational Medicine RESEARCH Open Access Identifcation of prognostic values defned by copy number variation, mRNA and protein expression of LANCL2 and EGFR in glioblastoma patients Hua‑fu Zhao1†, Xiu‑ming Zhou1,2†, Jing Wang3,4,5, Fan‑fan Chen1, Chang‑peng Wu1,6, Peng‑yu Diao1, Lin‑rong Cai1, Lei Chen1, Yan‑wen Xu1, Jing Liu7, Zong‑yang Li1, Wen‑lan Liu1, Zhong‑ping Chen3,4,5, Guo‑dong Huang1* and Wei‑ping Li1* Abstract Background: Epidermal growth factor receptor (EGFR) and lanthionine synthetase C‑like 2 (LanCL2) genes locate in the same amplicon, and co‑amplifcation of EGFR and LANCL2 is frequent in glioblastoma. However, the prognostic value of LANCL2 and EGFR co‑amplifcation, and their mRNA and protein expression in glioblastoma remain unclear yet. Methods: This study analyzed the prognostic values of the copy number variations (CNVs), mRNA and protein expression of LANCL2 and EGFR in 575 glioblastoma patients in TCGA database and 100 glioblastoma patients in tumor banks of the Shenzhen Second People’s Hospital and the Sun Yat‑sen University Cancer Center. Results: The amplifcation of LANCL2 or EGFR, and their co‑amplifcation were frequent in glioblastoma of TCGA database and our tumor banks. A signifcant correlation was found between the CNVs of LANCL2 and EGFR (p < 0.001). CNVs of LANCL2 or EGFR were signifcantly correlated with IDH1/2 mutation but not MGMT promoter methylation. Multivariate analysis showed that LANCL2 amplifcation was signifcantly correlated with reduced overall survival (OS) in younger (< 60 years) glioblastoma patients of TCGA database (p 0.043, HR 1.657) and our tumor banks (p 0.018, HR 2.199). -

However, human brain samples are collected post-mortem, reflecting mainly end stage disease. Because brain samples of mouse models can be collected at any stage of the disease process, they are useful to investigate PD progression. Here, we compare ventral midbrain transcriptomics profiles from α-synuclein transgenic mice with a progressive, early PD-like striatum neurodegeneration across different ages using pathway, gene set and network analysis methods. -
Systematic Elucidation of Neuron-Astrocyte Interaction in Models of Amyotrophic Lateral Sclerosis Using Multi-Modal Integrated Bioinformatics Workflow
ARTICLE https://doi.org/10.1038/s41467-020-19177-y OPEN Systematic elucidation of neuron-astrocyte interaction in models of amyotrophic lateral sclerosis using multi-modal integrated bioinformatics workflow Vartika Mishra et al.# 1234567890():,; Cell-to-cell communications are critical determinants of pathophysiological phenotypes, but methodologies for their systematic elucidation are lacking. Herein, we propose an approach for the Systematic Elucidation and Assessment of Regulatory Cell-to-cell Interaction Net- works (SEARCHIN) to identify ligand-mediated interactions between distinct cellular com- partments. To test this approach, we selected a model of amyotrophic lateral sclerosis (ALS), in which astrocytes expressing mutant superoxide dismutase-1 (mutSOD1) kill wild-type motor neurons (MNs) by an unknown mechanism. Our integrative analysis that combines proteomics and regulatory network analysis infers the interaction between astrocyte-released amyloid precursor protein (APP) and death receptor-6 (DR6) on MNs as the top predicted ligand-receptor pair. The inferred deleterious role of APP and DR6 is confirmed in vitro in models of ALS. Moreover, the DR6 knockdown in MNs of transgenic mutSOD1 mice attenuates the ALS-like phenotype. Our results support the usefulness of integrative, systems biology approach to gain insights into complex neurobiological disease processes as in ALS and posit that the proposed methodology is not restricted to this biological context and could be used in a variety of other non-cell-autonomous communication -
Genomic Landscape of Paediatric Adrenocortical Tumours

Dyer13, Alberto Pappo14, Jinghui Zhang2, James R. Downing10, Raul C. Ribeiro14,* & Gerard P. Zambetti1,* Paediatric adrenocortical carcinoma is a rare malignancy with poor prognosis. Here we analyse 37 adrenocortical tumours (ACTs) by whole-genome, whole-exome and/or transcriptome sequencing. Most cases (91%) show loss of heterozygosity (LOH) of chromosome 11p, with uniform selection against the maternal chromosome. IGF2 on chromosome 11p is overexpressed in 100% of the tumours. TP53 mutations and chromosome 17 LOH with selection against wild-type TP53 are observed in 28 ACTs (76%). Chromosomes 11p and 17 undergo copy-neutral LOH early during tumorigenesis, suggesting tumour-driver events. Additional genetic alterations include recurrent somatic mutations in ATRX and CTNNB1 and integration of human herpesvirus-6 in chromosome 11p. A dismal outcome is predicted by concomitant TP53 and ATRX mutations and associated genomic abnormalities, including massive structural variations and frequent background mutations. Collectively, these findings demonstrate the nature, timing and potential prognostic significance of key genetic alterations in paediatric ACT and outline a hypothetical model of paediatric adrenocortical tumorigenesis. 1 Department of Biochemistry, St Jude Children’s Research Hospital, Memphis, Tennessee 38105, USA. 2 Department of Computational Biology and Bioinformatics, St Jude Children’s Research Hospital, Memphis, Tennessee 38105, USA. -

Expression levels of 57,205 protein-coding and non-coding RNAs were studied as a function of aging by linear and negative binomial regression models. From both models, 1134 RNAs changed significantly with age. The most differentially abundant mRNAs encoded proteins implicated in several age-related processes, including cellular senescence, insulin signaling, and myogenesis. Specific mRNA isoforms that changed sig- nificantly with age in skeletal muscle were enriched for proteins involved in oxidative phosphorylation and adipogenesis. Our study establishes a detailed framework of the global transcriptome and mRNA isoforms that govern muscle damage and homeostasis with age. ✉ 1 National Institute on Aging–Intramural Research Program, National -

Mouse Lancl2 Conditional Knockout Project (CRISPR/Cas9)
https://www.alphaknockout.com Mouse Lancl2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Lancl2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Lancl2 gene (NCBI Reference Sequence: NM_133737 ; Ensembl: ENSMUSG00000062190 ) is located on Mouse chromosome 6. 9 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 9 (Transcript: ENSMUST00000050077). Exon 3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Lancl2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-291E6 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 3 starts from about 23.93% of the coding region. The knockout of Exon 3 will result in frameshift of the gene. The size of intron 2 for 5'-loxP site insertion: 9391 bp, and the size of intron 3 for 3'-loxP site insertion: 784 bp. The size of effective cKO region: ~1306 bp. The cKO region does not have any other known gene.

Computational Modeling-Based Discovery of Novel Classes of Anti-Inflammatory Drugs That Target Lanthionine Synthetase C- Like Protein 2
Computational Modeling-based Discovery of Novel Classes of Anti-inflammatory Drugs that Target Lanthionine Synthetase C- like Protein 2 Pinyi Lu Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Genetics, Bioinformatics and Computational Biology Josep Bassaganya-Riera, Chair Raquel Hontecillas-Magarzo David Bevan Stefan Hoops December 1, 2015 Blacksburg, VA Keywords: Lanthionine synthetase C-like protein 2, inflammation, drug discovery, molecular modeling, in silico clinical trial Copyright 2015, Pinyi Lu Computational Modeling-based Discovery of Novel Classes of Anti-inflammatory Drugs that Target Lanthionine Synthetase C-like Protein 2 Pinyi Lu ABSTRACT Lanthionine synthetase C-like protein 2 (LANCL2) is a member of the LANCL protein family, which is broadly expressed throughout the body. LANCL2 is the molecular target of abscisic acid (ABA), a compound with insulin-sensitizing and immune modulatory actions. LANCL2 is required for membrane binding and signaling of ABA in immune cells. Direct binding of ABA to LANCL2 was predicted in silico using molecular modeling approaches and validated experimentally using ligand-binding assays and kinetic surface plasmon resonance studies. The therapeutic potential of the LANCL2 pathway ranges from increasing cellular sensitivity to anticancer drugs, insulin- sensitizing effects and modulating immune and inflammatory responses in the context of immune-mediated and infectious diseases. A case for LANCL2-based drug discovery and development is also illustrated by the anti-inflammatory activity of novel LANCL2 ligands such as NSC61610 against inflammatory bowel disease in mice. This dissertation discusses the value of LANCL2 as a novel therapeutic target for the discovery and development of new classes of orally active drugs against chronic metabolic, immune- mediated and infectious diseases and as a validated target that can be used in precision medicine.
