Phosphoproteomics Data of pancreatic cancers cells treated with anlotinib

ABSTRACT: Aberrant regulation of angiogenesis involves in the growth and metastasis of tumors, but angiogenesis inhibitors fail to improve overall survival of pancreatic cancer patients in previous phase III clinical trials. A comprehensive knowledge of the mechanism of angiogenesis inhibitors against pancreatic cancer is helpful for clinical purpose and for the selection of patients who might benefit from the inhibitors. In this work, multi-omics analyses (transcriptomics, proteomics and phosphoproteomics profiling) were carried to delineate the mechanism of anlotinib, a novel angiogenesis inhibitor, against pancreatic cancer cells.

Serum proteomic profiling in patients with advanced Schistosoma japonicum-induced hepatic fibrosis

Project description:Background: Schistosoma japonicum (S. japonicum) is a parasitic flatworm that is the aetiological agent of human schistosomiasis, an important cause of hepatic fibrosis. Schistosomiasis-induced hepatic fibrosis is a consequence of the highly fibrogenic nature of egg-induced granulomatuous lesions, the main pathogenic factor of schistosomiasis. Although global awareness of the association between schistosomiasis-indued hepatic fibrosis and s. japonicum infection is increasing, little is known about the molecular differences associated with rapid progression to schistosomiasis in cirrhotic patients. Methods: We systematically used data-independent acquisition (DIA)-based liquid chromatography-mass spectrometry to identify differentially expressed proteins in serum samples from patients with advanced S. japonicum-induced hepatic fibrosis. Results: On the basis of our analysis, we identified 1,144 proteins, among which 66 were differentially expressed between the healthy control and SHF-F2 groups and 214 were differentially expressed between the SHF-F2 and SHF-F4 groups (up- or downregulation of at least 1.5-fold in serum samples). Furthermore, our results indicated that two selected proteins (C1QA and CFD) are potential biomarkers for distinguishing patients with SHF-F2 and SHF-F4 resulting from S. japonicum infection. Conclusions: This report is the first to provide a global proteomic profile of serum samples from patients with advanced S. japonicum-induced hepatic fibrosis. C1QA and CFD are potentially diagnostic markers for patients with SHF-F2 and SHF-F4 resulting from S. japonicum infection, although further large-scale studies are needed. Our DIA-based quantitative proteomic analysis revealed molecular differences among individuals with different stages of advanced S. japonicum-induced hepatic fibrosis and might provide fundamental information for further detailed investigations.

Comparative analysis of serum proteins between hepatitis B virus genotype B and C infection DIA-based quantitative proteomics

Project description:Hepatitis B virus (HBV) is an enveloped, coated, non-cytopathic and hepatotropic partially double-stranded DNA virus in the family Hepadnaviridae genus Orthohepadnavirus. Despite significant progress in the availability of safe vaccines and antiviral therapies against HBV, it still affects approximately 257 million people worldwide and is responsible for about 887,000 deaths per year around the world [4]. HBV infection, which are associated with acute and chronic liver failure responses to viruses attacked the liver, can result in inactive carrier state, chronic hepatitis, or fulminant hepatitis and put them at high risk to develop advanced liver fibrosis and cirrhosis, and even hepatocellular cancer. Many viral factors, which could affect the disparity of clinical outcomes or disease prognosis during chronic HBV infection, have been reported in previous studies; among them, the viral genotype, as well as HBV mutations ascribing the virus to a certain phenotype, was reported to be the most important factor influencing viral pathogenesis, including the change of host immune recognition, the enhanced virulence with increased HBV replication and the facilitation of cell attachment or penetration.

Pathogenic Bacteria Exploit Transferrin Receptor Transcytosis to Penetrate the Blood‒Brain Barrier

Project description:In this study, we present evidence showing that the infection with the major meningitis-causing bacteria, NMEC, GBS and SPN, activates the same fusion process of bacteria-containing vesicles (BCVs) with TfR vesicles, which enables those bacteria to exploit TfR transcytosis to penetrate the BBB, and illustrate the details of this process in HBMECs and mouse models.

Comparative genomic hybridization of kidney samples from Wilms tumor patients to accurately map 1p13 breakpoints

Project description:Wilms tumour karyotypes frequently exhibit recurrent, large-scale chromosomal imbalances, among the most common of which are concurrent loss of 1p and gain of 1q. We have previously identified a novel breakpoint at 1p13 by 1Mb-spaced array CGH, and undertook a fine-tiling oligonucleotide array approach to accurately map the region in four tumours exhibiting rearrangements at this locus. The use of a 10 bpspaced platform revealed that all four tumours in fact harboured different breakpoints, which were mapped to target four distinct genes PHTF1, DCLRE1B, TRIM33 and NRAS. The precise breakpoint interval was confirmed for one case to lie within intron 3 of DCLRE1B by quantitative copy number PCR and RT-PCR. In addition, expression profiling revealed a pattern of down- and up-regulation of genes either side of the breakpoint in all cases. Although it appears that no single gene is the driver of this rearrangement, this study highlights the power of fine-tiling oligonucleotide arrays to delineate breakpoint regions identified by other genome-wide screens.

Species-specific metabolic reprogramming in human and mouse microglia during inflammatory pathway induction

Project description:Metabolic reprogramming is a hallmark of the immune cells in response to inflammatory stimuli. This metabolic process involves a switch from oxidative phosphorylation (OXPHOS)to glycolysis, or alterations in other metabolic pathways. However, most of the experimental findings have been acquired in murine immune cells and little is known about the metabolic reprogramming of human microglia. In this study, we investigated the transcriptomic and metabolic profiles of mouse and iPSC-derived human microglia challenged with the TLR4 agonist LPS. We found that both species displayed a metabolic shift and an overall increased glycolytic gene signature in response to LPS treatment. The metabolic reprogramming was characterized by the upregulation of hexokinases in mouse microglia and phosphofructokinases in human microglia. This study provides the first direct comparison of energy metabolism between mouse and human microglia, highlighting the species-specific pathways involved in immunometabolism and the importance of considering these differences in translational research.

Nitric Oxide Enhances Resistance to PEG-induced Water Deficiency is Associated with the Primary Photosynthesis Reaction in Triticum aestivum L.

Project description:Photosynthesis is affected by water deficiency (WD) stress, and nitric oxide (NO) is a free radical that participates in the photosynthesis process. Previous studies have suggested that NO regulates the excitation energy distribution of photosynthesis under WD stress. Here, quantitative phosphoproteomic profiling was conducted using isobaric tags for relative and absolute quantitation. Differentially phosphorylated protein species (DEPs) were identified in leaves of NO or polyethylene glycol (PEG)-treated wheat seedlings (D) and in control seedlings, 2,257 unique phosphorylated peptides and 2,416 phosphorylation sites were identified from 1,396 unique phosphoproteins. Of these, 96 DEPs displayed significant changes (≥ 1.50-fold, p < 0.01). These DEPs are involved in photosynthesis and signal transduction, etc. Furthermore, phosphorylation of several DEPs were up-regulated by both D and NO treatments, but down-regulated only in NO treatment. These differences affected the chlorophyll A-B binding protein, chloroplast post-illumination chlorophyll fluorescence increase protein, and SNT7, implying that NO indirectly regulated the absorption and transport of light energy in photosynthesis in response to WD stress. The significant difference of chlorophyll (Chl) content, Chl a fluorescence transient, photosynthesis index, and trapping and transport of light energy further indicated that exogenous NO under D stress enhanced the primary reaction of photosynthesis compared to D treatment. A putative pathway is proposed to elucidate NO regulation of the primary reaction of photosynthesis under WD.
