Project description:Spider silk proteins are synthesized in the silk-producing glands, where the spidroins are produced, stored and processed into a solid fiber from a crystalline liquid solution. Despite great interest in the spider silk properties, that make this material suitable for biomedical and biotechnological applications, the mechanism of formation and spinning of the silk fibers has not been fully elucidated; and no combination of proteomic and transcriptomic study has been carried out so far in the spider silk-producing glands. Nephila clavipes is an attractive orb-web spider to investigate the spinning process of silk production, given the properties of strength, elasticity and biocompatibility of their silk fibers. Thus, considering that the combination of proteomic and transcriptomic analysis may reveal an extensive repertoire of novel proteins involved in the silk spinning process, and in order to facilitate and enable proteomics in this non-model organism, the current study aims to construct a high quality reference mRNA-derived protein database that could be used to identify tissue specific expression patterns in spider silk glands. Next-generation sequencing has offered a powerful and cost-efficient technique for the generation of transcriptomic datasets in non-model species using diverse platforms such as the Illumina HiSeq, Roche 454, Pacific Biosystems, and Applied Biosystems SOLiD; In the current study, the Illumina HiSeq 2000 platform will be used to generate a N. clavipes spider silk glands transcriptome-based protein database. The transcriptome data generated in this study will provide a comprehensive and valuable genomic resource for future research of the group of spider silk-producing glands, in order to improve our understanding of the overall mechanism of action involved in production, secretion, storage, transport, protection and conformational changes of spidroins during the spinning process, and prey capture; and the results may be relevant for scientists in material Science, biology, biochemistry, and environmental scientists.

Project description:. Here we provide a deeper insight into Xenopsylla cheopis salivary glands contents pairing transcriptome and proteomic approaches. Sequencing of 99 pairs of salivary glands from adult females X. cheopis yielded a total of 7,432 coding sequences functionally classified into 25 classes, in which the secreted class was found to be the most abundant one. The translated transcripts also served as a reference database for the proteomic study, which identified peptides from 610 different proteins.

Project description:The order Caudata of amphibians has been important in the study of tissue regeneration. The most complete genetic available data from salamanders are from Ambystoma mexicanum (Ambystomidae) and Notophthalmus viridescens (Salamandridae). Transcriptome data obtained with Next-generation sequencing technology has become a useful tool to discover new candidate genes in non-model organisms without a genome of reference. This study highlights the need of performing RNA-sequencing in other salamander species to compare and identify important clusters of genes that could be modulating important biological process in amphibians. Here we describe a de novo reference transcriptome and its annotation of a non-model terrestrial salamander, Bolitoglossa vallecula (Caudata: Plethodontidae). For this purpose, we utilized genome protein databases from vertebrates, nucleotide sequences obtained for salamander species, and a de novo reference transcriptomes of Bolitoglossa ramosi to conduct a homology analysis. While the majority of the transcripts recovered homologs with Bolitoglossa ramosi, only a minority of the data (22%; n= 94,739) recovered homologs with other vertebrates. We also compared the transcriptome profile of skin tissue between these Bolitoglossa species. We found a group of antimicrobial peptides, such as cathelicidins, which have been not previously described in salamanders and could be important modulators of different biological process. All animals used in this work were collected under the Contract on Genetic Access for scientific research for non commercial profit (Contrato de acceso a recursos genéticos para la investigación científica sin interés commercial) to Resources number 118–2015.

Project description:Streptococcus pyogenes, otherwise known as Group A Streptococcus (GAS), is an important and highly adaptable human pathogen with the ability to cause both superficial and severe diseases. Understanding how S. pyogenes senses and responds to its environment will likely aid in determining how it causes a breadth of diseases. One regulatory network involved in GAS’s ability to sense and respond to the changing environment is the Rgg2/3 quorum sensing (QS) system, which responds to metal and carbohydrate availability and regulates changes to the bacterial surface. To better understand the impact of Rgg2/3 QS on S. pyogenes physiology, we performed RNA-seq and TMT (tandem mass tag)-LC-MS/MS analysis on cells in which this system was induced with SHP pheromone or disrupted. Primary findings confirmed that pheromone stimulation in wildtype cultures is limited to the induction of operons whose promoters contain previously determined Rgg2/3 binding sequences. However, a deletion mutant of rgg3, a strain that endogenously produces elevated amounts of pheromone, led to extended alterations of the transcriptome and proteome, ostensibly by stress-induced pathways. Under such exaggerated pheromone conditions, a connection was identified between Rgg2/3 and the stringent response. Mutation of relA, the bifunctional guanosine tetra- and penta-phosphate nucleoside synthetase/hydrolase, and alarmone synthase genes sasA and sasB, impacted culture doubling times and disabled induction of Rgg2/3 in response to mannose, while manipulation of Rgg2/3 signaling modestly altered nucleotide levels. Our findings indicate that excessive pheromone production or exposure places stress on GAS resulting in an indirect altered proteome and transcriptome beyond primary pheromone signaling.
