Label-free shotgun proteomics of S. cerevisiae producing starch-like glucans

ABSTRACT: The synthesis of starch-like glucans can be reconstituted in S. cerevisiae using the genes from Arabidopsis thaliana: heterologous expression of SS1 to SS4, BE2, BE3, ISA1, and ISA2, together with a bacterial ADPglucose pyrophosphorylase gene for substrate provision in yeast strain 29, yielded insoluble granules with a semi-crystalline structure similar to that of plant amylopectin (Pfister et al., 2016). Here we conducted a label-free proteomics experiment to compare yeast strains with and without glucan production. This experiment was performed on strains 29, 48A, 362.1, 363.1 and WT (n = 4 replicates each, arising from independent replicate cultures). Strains including genotypes are described in the associated publication.

Cross-linked amyloidogenic proteins as potential aggregation inhibitors

Project description:Amyloidogenic proteins, characterized by their ability to form fibrillar aggregates with β sheet structure play an important role in several degenerative diseases, including Parkinson’s disease. Numerous amyloidogenic proteins, such as α synuclein, are intrinsically disordered (or contain ID regions, hence they also present as highly dynamic conformational ensembles in these regions. Aggregation is an inherent property of the polypeptide chains and under non physiological, appropriate conditions most of the proteins can aggregate and form polymers of various structures. Since amyloid fib ril s and oligomers are associated with a great variety of human diseases, inhibition of protein aggregation has great importance and it can be addressed by using small molecules, peptides or proteins. Our research aim was to study the potential application of modified forms of different amyloidogenic proteins as inhibitor molecules by introducing structural constraints in them. Under various conditions, different amyloidogenic proteins’ (α-synuclein and β2-microglobulin) monomer molecules have been cross linked intramolecularly and the heterogeneous mixtures has been fractionated by HPLC. The inhibitory potential of the isolated and effective molecules has been experimentally investigated by various methods ThT assay, TEM, CD spectroscopy). Furthermore, the locations of the crosslinks in the molecules were determined by mass spectrometry, and their structures are modeled in silico. Our results revealed that conformational constrains applied by cross linking on amyloidogenic proteins block their amyloid formation. Moreover, these molecules exhibited inhibitory effect on the aggregation of the unmodified proteins, as well.

Prochlorococcus marinus MED4 shotgun proteome dataset from “Protein cycling in the eastern tropical North Pacific oxygen deficient zone: a de novo-discovery peptidomic approach”

Project description:For this manuscript, the Prochlorococcus MED4 strain shotgun proteome dataset was used for benchmarking a de novo-directed sequencing approach. De novo peptide sequencing, where the sequence of amino acids is determined directly from mass spectra rather than by comparison (or peptide spectrum matching) to a selected database. We perform a benchmarking experiment using Prochlorococcus culture data, demonstrating de novo peptides are sufficiently accurate and taxonomically specific to be useful in environmental studies. The MED4 dataset herein represents the output from peptide spectrum matching using COMET within the transproteomic pipeline (TPP). Additional MED4 data outside this manuscript are included for both trypsin and Glu-C protease digestions as well as TPP output for post-translational modification searches. De novo output data derived from Peaks Studio can be found by referencing the manuscript publication.

Andrographis paniculata proteome

Project description:Andrographis paniculata (AP) is a medicinal herb used to treat infectious diseases. The medicinal properties are due to presence of andrographolide and other secondary metabolites synthesized via mevalonic acid (MVA) and methyl erythritol phosphate (MEP) pathways. To increase the andrographolide content plants were treated with 50µM Jasmonic acid (JA) for one week. HPLC analysis revealed that one fold increase in the andrographolide content compared to control. To study the signal mechanism underlying in the stress response, samples were subjected to Q-TOF-LC-MS/MS analysis. JA influences the expression of MVA and MEP enzymes in treated (22 enzymes) than in untreated (3 enzymes). We found total 3308 proteins in control and 3994 in elicited sample in which 1393 were commonly found in both. The differential expression revealed 621 proteins were down-regulated and 201 proteins were up regulated. The functional annotation involved 40 metabolic processes where post translational modifications was highly up regulated in treated (5.7%). The total proteome of A.paniculata was reported for the first time. The comparison of elicited and non elicited (control) samples revealed that the elicitation is an integrated process which release variety of bioactive compounds to defend itself from variety of pathogens. The Knowledge obtained from this scrutiny, JA dependent stress adaptive response is likely to have industrial and agricultural impact. It creates a hope towards future for the development of eco-friendly ways of managing pests and tapping into a largely unexplored treasure of plant-derived bioactive metabolites for human use. Particularly in this plant, it is useful for the production of medicines to cure different kinds of diseases and disorders.

LC-MS characterization of anti-PD-L1 and CXCR4 bispecific nanobodies

Project description:Antibodies and derivative drugs targeting immune checkpoints have been approved for the treatment of several malignancies, but there are fewer responses in patients with pancreatic cancer. Here, we designed a nanobody molecule with bi-targeting on PD-L1 and CXCR4, as both targets are overexpressed in many cancer cells and play important roles in tumorigenesis. The nanobody sequences targeting PD-L1 and CXCR4 were linked by the (G4S)3 flexible peptide to construct the anti-PD-L1/CXCR4 bispecific nanobody. The bispecific nanobody was expressed in E. coli cells and purified by affinity chromatography. The purified nanobody was biochemically characterized by mass spectrometry, Western blotting and flow cytometry to confirm the molecule and its association with both PD-L1 and CXCR4. The biological function of the nanobody and its anti-tumour effects were examined.

Chemerin effect on the endometrial proteome of the domestic pig during implantation obtained by LC-MS/MS analysis

Project description:Chemerin (CHEM) is a hormone mainly expressed in adipocytes involved in the regulation of energy homeostasis and inflammatory response. CHEM expression has been demonstrated in the structures of the porcine hypothalamic-pituitary-gonadal axis, as well as in the uterus, trophoblasts and conceptuses of pigs. In this study, we performed high-throughput proteomic analyses (Liquid Chromatography with Tandem Mass Spectrometry, LC-MS/MS) to examine the influence of CHEM (400 ng/ml) on differentially regulated proteins (DRPs) in the porcine endometrial tissue explants during implantation (15 to 16 days of gestation). Among all 352 DRPs, 164 were up-regulated and 188 were down-regulated in CHEM-treated group. DRPs were assigned to 47 gene ontology (GO) terms (p-adjusted < 0.05). Validation of four DRPs (IFIT5, TGFβ1, ACO1 and PGRMC1) by Western blot analysis confirmed the veracity and accuracy of LC-MS/MS method used in the present study. We suggest that CHEM, by modulating various protein expressions takes part in the endometrial cell proliferation, migration and invasion at the time of implantation. It also regulates the endometrial immune response, sensitivity to P4 and formation of new blood vessels. Additionally, CHEM appears to be an important factor involved in endothelial cell dysfunction during the pathogenesis of preeclampsia. The identification of a large number of DRPs under the influence of CHEM provides a valuable resource for understanding the molecular mechanisms of this hormone during implantation, which is a prerequisite for better control of pig reproduction.
