Published: March 1, 2023

Background Immune checkpoint inhibitors (ICIs) have dramatically improved survival in patients with cancer but are often accompanied by severe immune-related adverse events (irAEs), which can sometimes be irreversible. Insulin-dependent diabetes is a rare, life-altering irAE. Our purpose was to determine whether recurrent somatic or germline mutations observed who develop insulin-dependent as an Methods We performed RNA and whole exome sequencing on tumors from 13 developed due ICI exposure (ICI-induced mellitus, ICI-DM) compared control did not diabetes. Results In ICI-DM patients, we find differences expression of conventional type 1 autoantigens, observe significant overexpression ORM1, PLG, G6PC, all been implicated related pancreas islet cell function.

In this study, we aimed to study the role of extracellular proteins as biomarkers associated with newly diagnosed Type 1 diabetes (NT1D) diagnosis and prognosis. We retrieved analyzed GSE55098 microarray dataset from Gene Expression Omnibus (GEO) database. Using R software, screened out protein-differentially expressed genes (EP-DEGs) through several protein-related databases.

In silico identification and functional prediction of differentially expressed genes in South Asian populations associated with type 2 diabetes

PLoS ONE, Journal Year: 2023, Volume and Issue: 18(12), P. e0294399 - e0294399

Published: Dec. 14, 2023

Type 2 diabetes (T2D) is one of the major metabolic disorders in humans caused by hyperglycemia and insulin resistance syndrome. Although significant genetic effects on T2D pathogenesis are experimentally proved, molecular mechanism South Asian Populations (SAPs) still limited. Hence, current research analyzed two Gene Expression Omnibus (GEO) 17 Genome-Wide Association Studies (GWAS) datasets associated with SAP to identify DEGs (differentially expressed genes). The identified were further explore following a series bioinformatics approaches. Following PPI (Protein-Protein Interaction), 867 potential nine hub genes that might play roles pathogenesis. Interestingly, CTNNB1 RUNX2 found be unique for SAPs. Then, GO (Gene Ontology) showed biological, molecular, cellular functions DEGs. target also interacted different pathways In fact, 118 (including HNF1A TCF7L2 genes) directly Indeed, eight key miRNAs among 2582 significantly genes.

Abstract Renal proximal tubular reabsorption of proteins and polypeptides is tightly regulated by a concerted action the multi‐ligand receptors with subsequent processing from clathrin‐coated pits to early/recycling late endosomes towards lysosomes. We performed whole exome‐sequencing in male patient consanguineous family, who presented low‐ intermediate molecular weight proteinuria, nephrocalcinosis oligospermia. identified new potential player endocytosis, coiled‐coil domain containing 158 (CCDC158).

Exploring Computational Data Amplification and Imputation for the Discovery of Type 1 Diabetes (T1D) Biomarkers from Limited Human Datasets

Biomolecules, Journal Year: 2022, Volume and Issue: 12(10), P. 1444 - 1444

Published: Oct. 9, 2022

Background: Type 1 diabetes (T1D) is a devastating disease with serious health complications. Early T1D biomarkers that could enable timely detection and prevention before the onset of clinical symptoms are paramount but currently unavailable. Despite their promise, omics approaches have so far failed to deliver such biomarkers, likely due fragmented nature information obtained through single approach. We recently demonstrated utility parallel multi-omics for identification biomarker signatures. Our studies also identified challenges. Methods: Here, we evaluated novel computational approach data imputation amplification as one way overcome challenges associated relatively small number subjects in these studies. Results: Using proprietary algorithms, amplified our quadra-omics (proteomics, metabolomics, lipidomics, transcriptomics) dataset from nine thousand-fold analyzed using Ingenuity Pathway Analysis (IPA) software assess change its analytical capabilities prediction power datasets compared original. These showed ability identify an increased T1D-relevant pathways computationally datasets, especially, at ratios close “golden ratio” 38.2%:61.8%.

Published: Oct. 11, 2022

Abstract The acidic leucine-rich nuclear phosphoprotein 32 kDa (ANP32) family consists of evolutionarily conserved proteins 220–291 amino acids characterized by an N-terminal repeat domain (LRR) and a C-terminal low-complexity region (LCAR). ANP32 regulate variety physiological functions, including chromatin remodeling, apoptosis nervous system development. Abnormal expression is closely related to tumorigenesis. In recent years, the role in viral infections has received considerable attention due their activity supporting influenza virus replication restriction cross-species transmission. Moreover, are HIV nonsegmented negative-strand RNA viruses (NNSVs). this review, general functions proteins, as well roles replication, summarized detail.
