TL;DR: Deep insight is provided into the impact of mutation on the structure, function, stability, and mechanism of binding of GppNHp to the Rab5a at molecular level using MD simulations.
Abstract: Ras-related protein (Rab-5a) is primarily involved in the regulation of early endosome fusion during endocytosis and takes part in the budding process. During GTP hydrolysis, Rab5a was spotted in the cytoplasmic side of early endosomes in association with the GTP. Previous study suggested that the substitution of alanine with proline at position 30 of Rab5a reduces the GTPase activity around 12-fold, while, with arginine substitution stimulates the intrinsic GTP hydrolysis by 5-fold. Most of the other substitutions at this position show a little or no effect on the GTPase activity. In this paper, structure analysis and molecular dynamics (MD) simulation studies of human Rab5a and its mutants have been extensively carried out. The effect of binding of a non-hydrolyzable GTP analog guanosine-5'-(β, γ)-imidotriphosphate (GppNHp) with Rab5a and its mutants are described. The objective of the current study is to perform a detailed examination of structural flexibility of Rab5a and its mutants p.Ala30Pro and p.Ala30Arg using MD simulations. Our observations suggest that mutant p.Ala30Arg stabilize the protein molecule when bound to GppNHp which offers additional contacts. Despite an in silico approach, this study provides a deep insight into the impact of mutation on the structure, function, stability, and mechanism of binding of GppNHp to the Rab5a at molecular level.

TL;DR: It is concluded that the PPI complex and WGCNA co-expression network highlight the importance of phenotypic identifying hub gene signatures for BE and EAC.
Abstract: Esophageal adenocarcinoma (EAC) is a deadly cancer with high mortality rate, especially in economically advanced countries, while Barrett's esophagus (BE) is reported to be a precursor that strongly increases the risk of EAC. Due to the complexity of these diseases, their molecular mechanisms have not been revealed clearly. This study aims to explore the gene signatures shared between BE and EAC based on integrated network analysis. We obtained EAC- and BE-associated microarray datasets GSE26886, GSE1420, GSE37200, and GSE37203 from the Gene Expression Omnibus and ArrayExpress using systematic meta-analysis. These data were accompanied by clinical data and RNAseq data from The Cancer Genome Atlas (TCGA). Weighted gene co-expression network analysis (WGCNA) and differentially expressed gene (DEG) analysis were conducted to explore the relationship between gene sets and clinical traits as well as to discover the key relationships behind the co-expression modules. A differentially expressed gene-based protein-protein interaction (PPI) complex was used to extract hub genes through Cytoscape plugins. As a result, 403 DEGs were excavated, comprising 236 upregulated and 167 downregulated genes, which are involved in the cell cycle and replication pathways. Forty key genes were identified using modules of MCODE, CytoHubba, and CytoNCA with different algorithms. A dark-gray module with 207 genes was identified which having a high correlation with phenotype (gender) in the WGCNA. Furthermore, five shared hub gene signatures (SHGS), namely, pre-mRNA processing factor 4 (PRPF4), serine and arginine-rich splicing factor 1 (SRSF1), heterogeneous nuclear ribonucleoprotein M (HNRNPM), DExH-Box Helicase 9 (DHX9), and origin recognition complex subunit 2 (ORC2), were identified between BE and EAC. SHGS enrichment denotes that RNA metabolism and splicosomes play a key role in esophageal cancer development and progress. We conclude that the PPI complex and WGCNA co-expression network highlight the importance of phenotypic identifying hub gene signatures for BE and EAC.
