Project description:Drosophila translationally controled tumor protein (dTCTP) is important to repair double stranded DNA breaks in cell nucleus. However, besides damaged DNA loci, dTCTP is also located in interbands region of polytene chromsomes of salivary gland tissues. To address whether dTCTP is involved in transcriptional regulation process, we performed microarrays in salivary gland tissues from dTCTP mutants and w[1118] wildtype control. Salivary glands tissues were dissected and collected from 3rd instar larvae or each genotype for RNA extraction and hybridization on Affymetrix microarrays.

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.

Project description:Salivary glands are composed of several types of cells, and each cell type is predicted to be involved in the carcinogenesis of different types of cancers. In this study, we performed single nucleus RNA-seq on 3 human salivary gland samples to clarify the gene expression profile of each complex cellular component of the salivary glands.

Project description:Rabies is a fatal zoonotic disease posing a threat to the public health globally. Rabies virus (RABV) is excreted in the saliva of infected animals, and is primarily transmitted through bite contact. Salivary glands play an important role for virus propagation. However, the significance of salivary glands is less studied in RABV pathogenic mechanisms. To identify functionally important genes in the salivary glands, we employed RNA sequencing (RNA-seq) to establish and analyze mRNA expression profiles in parotid tissue infected with two RABV strains, CVS-11 and PB4. We map the transcriptome changes in response to RABV infection in parotid tissue for the first time. This work provides new clues to the study of RABV-affected salivary gland function and RABV transmission mechanisms in parotid tissue. And the salivary gland-enriched transcripts could be potential targets of interest for rabies disease control.

Project description:Recent work indicates that salivary glands are able to constitutively recruit CD8+ T cells and retain them as tissue resident memory T cells (TRM), independently of local infection, inflammation or antigen. To understand the mechanisms supporting T cell recruitment to the salivary gland, we compared T cell migration to the salivary gland in mice infected or not with murine cytomegalovirus (MCMV), a herpesvirus that infects the salivary gland and promotes the accumulation of salivary gland TRM. We found that acute MCMV infection increased rapid T cell recruitment to the salivary gland, but that equal numbers of activated CD8+ 44 T cells eventually accumulated in both infected and uninfected glands. T cell recruitment to uninfected salivary glands depended on chemokines and the integrin α4. Several chemokines were expressed in the salivary glands of both infected and uninfected mice and many of these could promote the migration of MCMV-specific T cells in vitro. MCMV infection increased expression of chemokines that interact with the receptors CXCR3 and CCR5, but neither receptor was needed for T cell recruitment to the salivary gland during MCMV infection. Unexpectedly however, the chemokine receptor CXCR3 was critical for T cell accumulation in uninfected salivary glands. Together, these data suggest that CXCR3 and the integrin α4 mediate T cell recruitment to uninfected salivary glands, but that redundant mechanisms mediate T cell recruitment after MCMV infection.

Project description:Salivary glands produce saliva and play essential roles in digestion and oral health. Pluripotent stem cell-derived (PSC) organoids provide a powerful platform for studying salivary gland development and developing new regenerative therapy. The previous protocol of PSC-derived salivary gland organoids required complicated manufacturing processes, which hampered the organoids for basic research and clinical application.Here, by mimicking the regulatory mechanism of developing salivary glands, we reported the differentiation of induced embryonic salivary glands (iE-SGs) from mouse embryonic stem cells by step-wise treatment of retinoic acid and FGF10. We showed that the iE-SGs recapitulated early morphogenetic events, including the thickening and invagination of the salivary gland placode, and then formed initial buds. The iE-SGs also differentiated into developing ducts structures and could develop to striated and excretory ducts when transplanted in vivo. RNA- seq revealed that iE-SGs had gene expression profiles similar to mouse embryonic SMGs. Thus, our study provided an easy and safe method to generate iE-SGs and offered possibilities for studying events during salivary gland morphogenesis in vitro

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.
