Host Proteins Interacting with Wild-Type and Signal Peptide-Cleaved GP64 of Bombyx mori Nucleopolyhedrovirus (BmNPV)

ABSTRACT: Bombyx mori nucleopolyhedrovirus (BmNPV) relies on the envelope glycoprotein GP64 to mediate host cell entry. Intriguingly, both the wild-type GP64 retaining its signal peptide (SP) and the SP-cleaved variant (SP∆nGP64) can support viral invasion, yet their mechanisms may differ. To identify potential GP64 receptors and dissect host interaction profiles, we performed comparative co-immunoprecipitation using purified GP64 and SP∆nGP64, followed by data-independent acquisition (DIA)-based proteomic analysis. A total of 6,064 and 5,247 host proteins were identified, respectively. Enrichment analyses revealed shared involvement in membrane trafficking, lipid metabolism, and endocytosis—pathways essential for viral entry.

Profiling Side Population Cells in Malignant Fibrous Histiocytoma

Project description:We are currently studying the mechanisms that confer tumour initiating potential upon SP, and as part of this work, we undertook gene profiling studies comparing expression between SP and non-SP cells, initially focusing on the most common soft tissue sarcoma, malignant fibrous histiocytoma (or MFH) Sarcomas contain a subpopulation of cells which exclude Hoechst dye (SP cells) and are enriched for tumor initiating potential. The persistence of SP cells could be responsible for relapse or a failed response to therapy. Expression profiles were compared between the SP and non-SP cells from malignant fibrous histiocytoma (MFH) tumors using microarray. The Hedgehog and Notch pathways were activated in SP cells. Blocking these pathways in MFH xenografts established in NOD-SCID mice depleted the abundance of SP cells and reduced tumor growth. Intriguingly, treatment also substantially inhibited the potential for successful secondary transplantation. The data provides support that SP cells act as tumor initiating cells in sarcomas and suggests targeting the SP as an enticing approach for sarcoma therapy. In this study, we studied six MFH tumours, and identified a number of signaling pathways that were consistently activated in the SP population compared to the non-SP population.

Development of gene expression signatures for breast cancer stem cells (SP cells)

Project description:To further compare gene expression profile between breast cancer stem cells (SP cells) and non-SP cells, we have employed illumina GEX microarray as a discovery platform to identify gene differential expression between SP with non-SP cells. SP analysis and sorting were done using a FACSVantage SE.The breast cancer cells were sorted into SP and non-SP cells.Total RNA was isolated from the FACS-sorted SP or non-SP cells, and gene expression signiture was detected by microarray.

Comparing the transcriptome of SP cells with that of non-SP cells in rainbow trout

Project description:In rainbow trout, type A spermatogonia can be split into SP cells and non-SP cells by the ability to exclude Hoechst 33342 dye (H33342). The H33342 fluorescence of SP cells are lower than that of non-SP cells, after H33342 staining. To investigate whether SP cells were transcriptomically distinct from non-SP cells, we compared the transcriptome of these cells. We used fluorescence-activated cell sorting (FACS) to isolate SP cells and non-SP cells from the type A spermatogonia in rainbow trout. To compensate unavailability of genetically uniform rainbow trout in independent sampling, SP cells and non-SP cells were collected at 3 times from 3 different parental fish groups. This experimental design allowed us to estimate effects specific to each parental fish genotype on mRNA expression in SP cells by a statistical modeling and to exclude the effects in subsequent analysis.

RNA-seq of mouse myeloma cell line SP 2/0 overexpressed with BC094916 against vector control

Project description:We found that a novel gene BC094916 mRNA significantly decreased in plasma cells. Because of plasmablast-like, mus musculus myeloma SP 2/0 cell line was selected to test the effect of BC094916 overexpression on plasmablast/plasma cells. BC094916 cDNA (General Biosystems, Anhui, China) was cloned into lentiviral vector LV122 or LV201 (Fugene Corp., Guangzhou, China) to generate BC094916 and BC094916-EGFP fusion protein, respectively. BC094916-expressing LV122 was then transfected into SP 2/0 cells, and stable transfectants were identified by drug selection (Puromycin, Sigma, 10 μg/ml). BC094916 overexpression suppressed SP 2/0 cell proliferation by inducing cell apoptosis. Importantly, BC094916 overexpression effectively suppressed tumor progression in the SP 2/0 xenograft mouse model. In addition, we found that BC094916 is a suppressive transcriptional factor. To verify its target genes, we determined mRNA profiles in BC094916-overexpressed and vector-transduced SP 2/0 cells by RNA-seq. RNA-seq was done with an Illumina HiSeq 2500 instrument at GENEWIZ, Suzhou, China.

Identification of bacterial secretins

Project description:Cyanobacteria and myxobacteria exhibit gliding motility that is associated with the secretion of an exopolymeric slime through nozzle-like structures. Using a combination of biochemical and structural approaches, we demonstrate that these nozzles are composed of secretins belonging to the PilQ/GspD family; proteins previously characterized as forming outer membrane gates in type-two secretion systems (T2SSs) and other bacterial secretion machineries. We show that gspD is an essential gene in Myxococcus xanthus, and that its conditional knockdown impairs both A-motility-associated exopolymer (AEP) slime secretion and gliding motility. In cyanobacteria, available data indicate that the exopolymeric slime is a polysaccharide, whereas the precise composition of the slime in myxobacteria remains unresolved. These findings suggest that secretins can mediate the secretion of non-proteinaceous polymers in certain bacteria.

Differential gene expression profiles of side population and non-side population cells of malignant pleural mesothelioma

Project description:Malignant pleural mesothelioma (MPM), which is associated with occupational asbestos exposure, is a deadly disease with no effective treatments due mainly to its high resistance to anti-cancer drugs. The molecular mechanisms responsible for its chemotherapeutic resistance are complicated and undefined. However, the presence of side population cells (SP cells) in tumors is a well-accepted explanation for their anti-cancer drug resistance. To identify SP cell-specific gene expression signature, microarray technique has been employed. Our data show differential gene expression profiles between SP and non-SP cells of H2714 mesothelioma cells. SP cells over-expressed genes associated with cancer stem cell (CSC) and drug resistance: DUSP6, SPRY2 and IL6, as well as multi-pathways, including the cancer stem cell-associated pathways Notch and c-Kit. Therefore, we believe that targeting CSC-specific genes and pathways in SP cells may hold the key to the discovery of effective treatments for reversing chemotherapeutic resistance to MPM treatment. 4 samples

Proteome Analysis of Actinoplanes sp. SE50/110

Project description:The acarviose metabolite acarbose is an a glucosidase inhibitor produced by Actinoplanes sp. SE50/110. It is medically important because it is used in the treatment of type 2 diabetes. In this work a comprehensive proteome analysis of Actinoplanes sp. SE50/110 was carried out. The associated txt and RAW files were used for two different analyses and publications. While one study focused on a comparative analysis of Actinoplanes sp. SE50/110 to elucidate differences in the proteome cultures that were grown with either maltose or glucose, the other study applied spectral counting and analyzed only the maltose-grown cultures to determine the major proteins and their location in the cell. The txt files for the comparative data are labeled as "heavy_light" and of the spectral counting data as "light". Both datasets were derived from the same RAW files.
