Molecular biology and evolution 20220301 3

Insects have evolved numerous adaptations and colonized diverse terrestrial environments. Several polyneopterans, including dictyopterans (cockroaches and mantids) and locusts, have developed oothecae, but little is known about the molecular mechanism, physiological function, and evolutionary significance of ootheca formation. Here, we demonstrate that the cockroach asymmetric colleterial glands produce vitellogenins, proline-rich protein, and glycine-rich protein as major ootheca structural pro ...[more]

Integrative Transcriptomic and Proteomic Analysis Reveals Mechanisms of Silica-induced Pulmonary Fibrosis in Rats

Project description:To explore proteomic and transcriptomic changes in rat model of silicosis, transcriptomic analysis by microarray and tandem mass tags (TMT)-based proteomic analysis were performed to reveal the expression of mRNAs and proteins in lung tissues. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were applied to analyze the alterated genes and proteins. The integrated analysis was performed between transcriptome and proteome. Furthermore, the data were further verified by RT-qPCR and parallel reaction monitoring (PRM). In total, 244 differentially expressed proteins (DEPs) showed the same trend as that of the corresponding differentially expressed genes (DEGs) (named DEPs/DEGs). GM2a, CHI3L1, LCN2 and GNAI1, which were validated consistently by RT-qPCR and PRM, are involved in the extracellular matrix (ECM) and inflammation contributed to fibrosis in silicosis.

Bovine skeletal muscle gene network

Project description:We present the application of large-scale multivariate mixed-model equations to the joint analysis of nine gene expression experiments in beef cattle muscle and fat tissues with a total of 147 hybridizations, and exploring 47 experimental conditions or treatments. Using a correlation-based method, we constructed a gene network for 822 genes. Modules of muscle structural proteins and enzymes, extracellular matrix, fat metabolism and protein synthesis were clearly evident. Detailed analysis of the network identified groupings of proteins on the basis of physical association. For example, expression of three components of the z-disk, MYOZ1, TCAP and PDLIM3, was significantly correlated. In contrast, expression of these z-disk proteins was not highly correlated with the expression of a cluster of thick (myosins) and thin (actin and tropomyosins) filament proteins, or titin, the third major filament system. However, expression of titin was itself not significantly correlated with the cluster of thick and thin filament proteins and enzymes. Correlation in expression of many fast twitch muscle structural proteins and enzymes was observed, but slow twitch specific proteins were not correlated with the fast twitch proteins or with each other. In addition, a number of significant associations between genes and transcription factors were also identified. Our results not only recapitulate the known biology of muscle, but have also started to reveal some of the underlying associations between and within the structural components of skeletal muscle.

Quantitative Exploratory Proteomics Analysis of Glioblastoma in Initial and Recurrent Tumors

Project description:Shotgun Proteomics; Glioblastoma samples from 11 patients were obtained at initial and recurrent tumor stages. Proteins were extracted, identified and quantified via tandem mass spectrometry based on a TMT isobaric labelling approach. Quatitative proteomics reveals 146 differentially abundant proteins using a patient-matched statistical modelling. Analysis of proteolytic processing reveals differential proteolytic patterns in recurrent tumors. Proteogenomics reveals the presense of 30 single-amino acid variants present in glioblastoma tumor and 1 of those as increased in recurrent tumor.

Cisplatin, Carboplatin, and Oxaliplatin Interactions With Plasma Proteins

Project description:Cisplatin is a widely used anti-tumor agent for the treatment of testicular and ovarian cancers. Carboplatin is used extensively for small cell, non small cell lung cancer and ovarian cancer. Oxaliplatin has recently been approved in the United States (US) for treatment of colorectal cancer. A large portion (in the range of 65% to 98%) of cisplatin in the blood plasma was bound to protein within a day after intravenous administration. The binding of cisplatin and other analogues to proteins and enzymes is generally believed to be the cause of several severe side effects such as ototoxicity and nephrotoxicity. The interactions between platinum based chemotherapy drugs and proteins is proposed to play important roles in both drug activity and toxicity. Therefore, a better understanding of the molecular mechanism of platinum-protein interactions may have an impact on optimization of strategies for treatment. The objective is to develop novel approaches and techniques to provide detailed mechanistic, kinetic and high-resolution structural information on the binding of platinum analogues to blood proteins, and to improve treatment efficacy and reduce side effects.

Whole genome bisulfite sequencing and Infinium Mouse Methylation BeadChip using fresh and fresh-frozen mouse epidermis (WGBS)

Project description:We compared the global DNA methylation levels of hairless mouse epidermis using the Infinium Mouse Methylation BeadChip from Illumina and whole genome bisulfite sequencing (WGBS). We also studied the effect of sample storage conditions by using fresh and fresh-frozen epidermis. The DNA methylation levels of xxx,xxx CpG sites covered by both the BeadChip and WGBS were compared. DNA methylation levels obtained with WGBS and the BeadChip were strongly correlated (Pearson correlation r = 0.984). We applied a threshold of 15 reads for the WGBS methylation analysis. Even at a threshold of 10 reads, we observed no substantial difference in DNA methylation levels compared with that obtained with the BeadChip. The DNA methylation levels from the fresh and the fresh-frozen samples were strongly correlated when analysed with both the BeadChip (r = 0.996) and WGBS (r = 0.994). We conclude that the two methods of analysis generally work equally well for studies of DNA methylation of mouse epidermis and find that fresh and fresh-frozen epidermis can generally be used equally well. The choice of method will depend on the specific study’s aims and the available resources in the laboratory.

Project description:We compared the global DNA methylation levels of hairless mouse epidermis using the recently released Infinium Mouse Methylation BeadChip from Illumina and whole genome bisulphite sequencing (WGBS). We also studied the effect of sample storage conditions by using fresh and fresh-frozen epidermis. The DNA methylation levels of 123,851 CpG sites covered by both the BeadChip and WGBS were compared. DNA methylation levels obtained with WGBS and the BeadChip were strongly correlated (Pearson correlation r = 0.984). We applied a threshold of 15 reads for the WGBS methylation analysis. Even at a threshold of 10 reads, we observed no substantial difference in DNA methylation levels compared with that obtained with the BeadChip. The DNA methylation levels from the fresh and the fresh-frozen samples were strongly correlated when analysed with both the BeadChip (r = 0.999) and WGBS (r = 0.994). We conclude that the two methods of analysis generally work equally well for studies of DNA methylation of mouse epidermis and find that fresh and fresh-frozen epidermis can generally be used equally well.

Key metabolism pathways and regulatory mechanisms of high polysaccharide yielding in Hericium erinaceus

Project description:The genome of H. erinaceus original strain HEA was reported 38.16 Mb, encoding 9,780 predicted genes by single-molecule, real-time sequencing technology. The phylogenomic analysis showed that H. erinaceus had the closest evolutionary affinity with Dentipellis sp. The polysaccharide content in the fermented mycelia of mutated strains HEB and HEC, which obtained by ARTP mutagenesis in our previous study, was improved by 23.25% and 47.45%, and a new β-glucan fraction with molecular weight 1.056×10^6 Da was produced in HEC. Integrative analysis of transcriptome and proteomics showed the upregulation of the carbohydrate metabolism pathway modules in HEB and HEC might lead to the increased production of glucose-6P and promote the repeating units synthesis of polysaccharides. qPCR and PRM analysis confirmed that most of the co-enriched and differentially co-expressed genes involved in carbohydrate metabolism shared a similar expression trend with the transcriptome and proteome data in HEB and HEC. Heatmap analysis showed a noticeably decreased protein expression profile of the RAS-cAMP-PKA pathway in HEC with a highly increased 47.45% of polysaccharide content. The S phase progression blocking experiment further verified that the RAS-cAMP-PKA pathway's dysfunction might promote high polysaccharide and β-glucan production in the mutant strain HEC.
