IL-22 regulation of functional gene expression in salivary gland cells

ABSTRACT: Microarray analysis using the HumanHT-12 v4 Expression BeadChip was utilized to determine the biological function of IL-22. The data indicate an extensive effect of IL-22 on many major molecular functions including activation of antimicrobial genes and downregulation of immune-associated pathways. Functional studies performed in-vitro using human salivary gland cells treated with IL-22 indicated a direct effect of IL-22 on cell cycling, specifically reducing cellular proliferation at the G2-M phase by activation of STAT3. Total RNAs were obtained from salivary gland cells stimulated with recombinant IL-22 for 45 minutes. Differential expression analyses were conducted using the LIMMA package from the Bioconductor project. MTT assay, flow cytometry and western blotting were used to identify the function of IL-22 on human salivary gland cells.

Transcriptomic and functional analysis of the Anopheles gambiae salivary gland in relation to blood feeding

Project description:Background: The Anopheles gambiae salivary glands play a major role in malaria transmission and express a variety of bioactive components that facilitate blood-feeding by preventing platelet aggregation, blood clotting, vasodilatation, and inflammatory and other reactions at the probing site on the vertebrate host. Results: We have performed a global transcriptome analysis of the A. gambiae salivary gland response to blood-feeding, to identify candidate genes that are involved in hematophagy. A total of 4,978 genes were found to be transcribed in this tissue. A comparison of salivary gland transcriptomes prior to and after blood-feeding identified 52 and 41 transcripts that were significantly up-regulated and down-regulated, respectively. Ten genes were further selected to assess their role in the blood-feeding process using RNAi-mediated gene silencing methodology. Depletion of the salivary gland genes encoding D7L2, anophelin, peroxidase, the SG2 precursor, and a 5'nucleotidase gene significantly increased probing time of A. gambiae mosquitoes and thereby their capacity to blood-feed. Conclusions: The salivary gland transcriptome comprises approximately 38% of the total mosquito transcriptome and a small proportion of it is dynamically changing already at two hours in response to blood feeding. A better understanding of the salivary gland transcriptome and its function can contribute to the development of pathogen transmission control strategies and the identification of medically relevant bioactive compounds.

mRNA-seq of mouse salivary gland cancer cells cultured in adherent or non-adherent culture

Project description:Aim: investigate how the Wnt-driven Mll1 epigenome regulates salivary gland and head and neck cancer. We performed mRNA-seq and ChIP-seq of H3K4me1, me2 and me3 on mouse salivary gland cancer cells that are kept in two different growth conditions, adherent culture and non-adherent sphere culture. Mouse salivary gland cancer cells were isolated from salivary gland of transgenic mouse that harbor K14-Cre-induced Wnt/β-catenin gain-of-function and Bmpr1a loss-of-function mutations.

Identification of Drosophila salivary gland secreted proteins through LC-MS/MS

Project description:As we observed that salivary gland ablation induced retardation of systemic growth, it raised the possibility that salivary glands might secrete a growth factor-like peptide into the hemolymph to regulate systemic growth. To identify potential salivary gland-derived peptides with endocrine activity, we performed liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis and investigated the changes in the hemolymph proteome following salivary gland ablation.

Proteomic analysis of salivary glands of female Aedes aegypti Linn

Project description:Aedes aegypti is a major vector for dengue, chikungunya and yellow fever. Though salivary gland plays a crucial role in transmission of virus and vector life cycle, there is no global and unbiased published report on salivary gland proteome of Ae. aegypti. In this study, we have carried out mass spectrometry based proteomic analysis of salivary gland from adult female Ae. aegypti mosquitoes. By fractionating the proteins isolated from salivary gland on SDS-PAGE and analyzing the in-gel digested bands on high resolution mass spectrometry, we identified 1,205 proteins. This is by far the largest catalogue of salivary gland proteome of Ae. aegypti. These proteins were then assigned molecular functions and biological processes. Several immunity related pathways were found to be enriched in salivary gland. In addition, subset of proteins was predicted to secretory in nature and may play an important role during blood feeding. This study provides a useful resource of proteins expressed in salivary gland of Ae. aegypti female mosquitoes and will aid in biomedical research focused on development of transmission blocking vaccine.

Atlas of Gene Expression at Microanatomical Resolution of the Submandibular Salivary Gland

Project description:The goal of this study was to generate a spatiotemporal atlas of gene expression in the developing salivary gland. This will allow us to identify changes in gene expression that may result in the formation of the different domains of the salivary gland. At least 4 microarrays per location per time point were collected. The originating samples are rather small, so many clefts, ducts and buds had to be pooled to generate enough aRNA for hybridization. Supplementary file: cluster heat map from anova 0.05 passing entities, E12.5 main bud vs E15 main bud (averaged readings)

CGH Salivary Gland - OregonR

Project description:modENCODE_submission_722 This submission comes from a modENCODE project of David MacAlpine. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: Most terminally differentiated Drosophila tissues are either polyploid or polytene. Unlike normal chromosomes, where the entire chromosome must be replicated exactly once, polytene chromosomes are often differentially replicated with many regions underreplicated and some overreplicated. We will characterize five different polytene tissues using comparative genomic hybridization (CGH) to identify differentially replicated regions of each chromosome. These studies will also identify tissue specific amplicons, where the replication mediated amplification of specific loci is essential for up-regulation of mRNA levels encoding proteins critical for development. The differential replication of polytene chromosomes in Drosophila will provide a unique opportunity to understand how developmental cues and chromosomal domains influence replication initiation. Keywords: CGH For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CGH.

ChIP-seq of H3K4me1, me2 and me3 on mouse salivary gland cancer cells cultured in either adherent or non-adherent conditions

Project description:Investigating how the Wnt-driven Mll1 epigenome regulates salivary gland and head and neck cancer. We performed mRNA-seq and ChIP-seq of H3K4me1, me2 and me3 on mouse salivary gland cancer cells that are kept in two different growth conditions, adherent culture and non-adherent sphere culture. Mouse salivary gland cancer cells were isolated from salivary gland of transgenic mouse that harbor K14-Cre-induced Wnt/β-catenin gain-of-function and Bmpr1a loss-of-function mutations. Anti-H3K4me1 (C15410194), -me2 (C15410035) and -me3 (C15410003-50) antibodies were purchased from Diagenode. ChIP-seq was performed according to the protocols provided by Diagenode using the iDeal ChIP-seq kit for histones and the iDeal library preparation kit. For mRNA-seq, mRNA was extracted according to the standard TRIzol protocol (Invitrogen) and subjected to library preparation using the TruSeq stranded mRNA library preparation kit. Sequencing was performed with the TruSeq SBS Kit v3-HS (2 X 200 cycles) on an Illumina HiSeq 2000 sequencer.
