Photoreactive groups are invaluable tools in structural proteomics, offering reagent-free activation and temporal control of protein labelling. However, traditional UV-activatable functional groups often produce unstable intermediates and diverse products, making these chemistries difficult to deploy at scale. In this study, we performed a systematic analysis of ortho-nitrobenzyl alcohol (oNBA) reactivity for integration into novel reagents for chemical crosslinking-mass spectromet ...[more]

Site-specific N-linked glycosylation of recombinant SARS-CoV-1 and -2 Receptor Binding Domain from GnTI-/- cells

Project description:Fusion proteins of the SARS-CoV-1 and SARS-CoV-2 spike receptor binding domain with a fluorescent protein were created in monomeric and trimeric form as tools for receptor binding studies in cultured cells and animal tissues. Here, site specific N-linked glycosylation in the proteins expressed from GnTI-/- cells is profiled with LC-MS/MS, using electron transfer high-energy collision dissociation

Single-cell RNA-seq of mouse cerebral cortex

Project description:We have applied a recently developed, highly accurate and sensitive single-cell RNA-seq method (STRT/C1) to perform a molecular census of two regions of the mouse cerebral cortex: the somatosensory cortex and hippocampus CA1. We isolated cells fresh from somatosensory cortex (S1) and hippocampus CA1 area of juvenile (P22 - P32) CD1 mice, 33 males and 34 females. Cells were collected without selection, except that 116 cells were obtained by FACS from 5HT3a-BACEGFP transgenic mice. A total of 76 Fluidigm C1 runs were performed, each attempting 96 cell captures and resulting in 3005 high-quality single-cell cDNAs, containing Unique Molecular Identifiers allowing counting of individual mRNA molecules, even after PCR amplification.

Blood plasma proteomic profiles of pink salmon Oncorhynchus gorbuscha Walbaum, 1792 during spawning migration

Project description:The pink salmon (Oncorhynchus gorbuscha) is a commercial anadromous fish species of the family Salmonidae. The species has a peculiar life cycle that includes spawning migration from marine to freshwater environments, which is accompanied by significant adaptive changes in the body, both the physiological and biochemical. This study described and revealed the variability of blood plasma proteomes of female and male pink salmon collected from three different biotopes - marine, estuarine and riverine - that the fish pass through spawning migration. Identification and comparative analysis of pink salmon blood plasma protein profiles were performed using proteomic and bioinformatic approaches. Blood proteomes of female and male spawners collected from different biotopes were qualitatively and quantitatively distinguished. Females differed primarily by proteins associated with reproductive system development (certain vitellogenin and choriogenin), lipid transport (fatty acid binding protein) and energy production (fructose 1,6-bisphosphatase), and males - by proteins involved in blood coagulation (fibrinogen), immune response (lectins) and reproductive processes (vitellogenin). Differentially expressed sex-specific proteins were implicated in proteolysis (aminopeptidases), platelet activation (β- and γ-chain fibrinogen), cell growth and differentiation (a protein containing the TGF_BETA_2 domain) and lipid transport processes (vitellogenin and apolipoprotein). The results obtained are of fundamental and practical importance, providing to the existing knowledge of biochemical adaptations to spawning of pink salmon, representative of the economically important migratory fish species.

Transposon random mutagenesis of Mycoplasma pneumoniae M129 using ProTInSeq protocol along different concentrations and using two positive selection markers (Chloramphenicol acetyltransferase and Erythromycin esterase EreA) and a negative selection marker (barnase)

Project description:Definition of different Tn4001-derived mini-transposons carrying reporters with no translation initiation codons so they can only be expressed when fused to an endogenous protein. We used Chloramphenicol acetyltransferase (Cm) as a positive selection marker while the RNAse barnase (Barn) was used as a negative one. In this case, the mini-transposon has a constitutively expressed chloramphenicol resistance gene downstream to the Barn gene. Also, Erythromycin esterase EreA (Ery) was used to evaluate the effect of oligomerization of protein-fusion resistances, as Ery is a dimeric resistance while Cm forms a tetramer. In the positive selection, for the bacteria to survive in the presence of Chloramphenicol, the transposed reporter needs to be inserted in-frame to a genome protein-coding sequence. In the negative selection, the transposed gene should be out of frame with the genome protein-coding sequence for the bacteria to survive.

Transcription profiling of Pseudomonas aeruginosa exposed to toxicogenomic effects of ortho-phenylphenol

Project description:In the present study, we employed Affymetrix Pseudomonas aeruginosa GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Pseudomonas aeruginosa to ortho-phenylphenol, which involved initial growth inhibition and metabolism. Experiment Overall Design: We conducted four independent microarray experiments (biological replicates) in the absence (control) and the presence (experimental) of ortho-phenylphenol. We calculated fold change as the ratio between the signal averages of four untreated (control) and four ortho-phenylphenol-treated (experimental) cultures for 0, 20 and 60 min exposures.
