Genome wide microarray based expression profiles associated with BmNPV resistantance and susceptibility in Indian silkworm races of Bombyx mori

ABSTRACT: The molecular mechanism involved in BmNPV resistance was investigated using a genome wide microarray in the midgut tissues of BmNPV infected resistant (Sarupat) and susceptible (CSR-2) Indian silkworm races. In the resistant race, 735 genes were upregulated and 589 genes were down regulated at 12 hours of BmNPV post infection. Similarly in case of susceptible race, 2183 genes were up regulated and 2115 genes were down regulated. Among the differentially expressed genes, nine upregulated and eight down regulated genes were validated using real time qPCR analysis. In Sarupat, the significantly upregulated genes are vacuolar protein sorting associated gene, X fin like protein and Carboxy peptidase E like protein in BmNPV infected midguts, whereas the prominent down regulated genes are glutamate receptor ionotropic kainite 2-like, BTB/POZ domain and transferrin. In the case of CSR-2, the considerably upregulated genes are Peptidoglycan recognition protein S6 precursor and rapamycin while the conspicuous down regulated genes are facilitated trehalose transporter and zinc transporter ZIP1-like gene. Our results provided a vital insights of Bombyx mori in reference with its molecular mechanism in immune response against the BmNPV invasion.

Ziziphus nummularia transcriptome analysis under drought

Project description:Ziziphus nummularia is well distributed in the Thar desert encompassing India and Pakistan. It survives in regions with an average annual rainfall lesser than 100 mm. Transcriptome profiling was done in Z. nummularia genotype CIAHZN-J under control and drought-stress at -0.3MPa. Among the unique transcripts identified, 283 were found to be downregulated and 554 upregulated in comparison to control. The important down-regulated transcripts identified were: LRR receptor like serine/threonine protein kinases, oligo peptide transporter OPT family, myrcene synthase, LRR protein kinase family isoform1, ATP binding cassette transporter, phytochrome kinase, Pectin estrase inhibitor like-35, auxin efflux facilitator isoform 1, multidrug resistance protein, pectin methyl esterase 3 and ABC transporter B family. Similarly some of the upregulated transcripts are: Raffinose synthase family protein, wall associated receptor kinase like, acyl transferase like protein, cadmium/zinc transporting ATPase 3 like, sucrose synthase 6-like, cytochrome P-450 like, phosphatase 2C family protein and TT12-2 MATE transporter. This study will be very useful to identify novel genes that may be involved in drought tolerance of Z. nummularia.

High-throughput pyrosequencing of endogenous small RNAs from CSR-1 IP complexes and csr-1(tm892) and ego-1(om97) mutants

Project description:High-throughput pyrosequencing of endogenous small RNAs from CSR-1 IP complexes and csr-1(tm892) and ego-1(om97) mutants with corresponding controls. RNAi-related pathways regulate diverse processes, from developmental timing to transposon silencing. Here, we show that in C. elegans the Argonaute CSR-1, the RNA-dependent RNA polymerase EGO-1, the Dicer-related helicase DRH-3, and the Tudor-domain protein EKL-1 localize to chromosomes and are required for proper chromosome segregation. In the absence of these factors chromosomes fail to align at the metaphase plate and kinetochores do not orient to opposing spindle poles. Surprisingly, the CSR-1 interacting small RNAs (22G-RNAs) are antisense to thousands of germline-expressed protein-coding genes. Nematodes assemble holocentric chromosomes in which continuous kinetochores must span the expressed domains of the genome. We show that CSR-1 interacts with chromatin at target loci, but does not down-regulate target mRNA or protein levels. Instead, our findings support a model in which CSR-1 complexes target protein-coding domains to promote their proper organization within the holocentric chromosomes of C. elegans. 5 samples examined. Small RNAs that co-immunopercipitate with CSR-1 protein and input sample. Small RNAs from csr-1(tm892) and ego-1(om97) mutants and corresponding congenic wild type strain.

CSR-1A post-translational modification

Project description:CSR-1 is an essential Argonaute protein that binds to a subclass of 22G-RNAs targeting most germline-expressed genes. Here we show that the two isoforms of CSR-1 have distinct expression patterns; CSR-1B is ubiquitously expressed throughout the germline and during all stages of development while CSR-1A expression is restricted to germ cells undergoing spermatogenesis. Furthermore, CSR-1A associates preferentially with 22G-RNAs mapping to spermatogenesis-specific genes whereas CSR-1B-bound small RNAs map predominantly to oogenesis-specific genes. Interestingly, the exon unique to CSR-1A contains multiple dimethylarginine modifications, which are necessary for the preferential binding of CSR-1A to spermatogenesis-specific 22G-RNAs. Thus, we have discovered a regulatory mechanism for C. elegans Argonaute proteins that allows for specificity of small RNA binding between similar Argonaute proteins with overlapping temporal and spatial localization.

The Possible Protective Role of Omeprazole Against Oxaliplatin Induced Neuropathy in Cancer Patients

Project description:Oxaliplatin(OXA) chemotherapy protocols are used in treatment of cancers like colorectal (CRC) and pancreatic cancer. OXA causes peripheral neuropathy which is considered treatment limiting factor. In recent studies, it shows that omeprazole(OME) has antioxidant effect and can inhibit organic cation transporter 2 (OCT2) in kidney. So OME can protect against peripheral neuropathy induced by OXA through oxidative stress . Also OME activates extracellular-signal-regulated kinase(ERK) / mitogen activated protein kinase ( MAPK) pathway, so improves demyelinating symptoms.

Chlorocebus sabaeus vero E6 and and eIF4E(S209A) Vero cells (S209A-Vero) LC-MSMS upon infection by coronavirus PEDV

Project description:Two rounds of TMT relative quantitative proteomics were performed to detect cellular factors involved in p-eIF4E regulation of the synthesis of viral proteins.our first round of screening identified differentially expressed proteins in PEDV-infected cells and mock-infected cells; the cellular pathways involved were mainly the estrogen, cAMP, and calcium signaling pathways. Second round screening identified differentially expressed proteins in the PEDV-infected S209A-Vero cells vs. the PEDV-infected WT-Vero cells; the regulated cellular pathways were found to be mainly in the PI3K-Akt, focal adhesion, and mTOR signaling pathways, and the biological processes and molecular functions in which p-eIF4E played a role were related mainly to metabolism and biogenesis, catalytic activity, and stimuli response.4006 host factors were detected, of which 193 (in brown) were significantly upregulated (ratio ≥1.2, P＜0.05) and 191 (in green) were down-regulated upon PEDV infection (ratio ≤0.83, P＜0.05). 29 of the 191 down-regulated proteins were susceptible to a low level of p-eIF4E . Notably, among the 193 upregulated cellular proteins, 77 were upregulated in the WT-Vero over the S209A-Vero cells , suggesting that the WT-Vero cells are more susceptible to a high level of p-eIF4E.

Post-transcriptionally regulated genes are essential for pluripotent stem cell survival

Project description:Here, by combining transcriptome and proteome profiling, we identified 228 post-transcriptionally regulated genes with strict regulation at the protein level in PSCs. Among them, 84 genes were found necessary for the survival of several cell types including PSCs, and 20 genes were identified as specific for the survival of PSCs. These 20 proteins were upregulated only in PSCs and not in differentiated cells derived from the three germ layers. Subcellular fractionation of the mRNA showed that the expression level of most of the 20 proteins was regulated at the mRNA localization stage from the nucleus to the cytoplasm in PSCs, but their translation efficiency was unchanged compared with other cell types. Together, these results reveal a critical function of post-transcriptionally regulated genes on PSC survival.
