Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

Project description:Vascular smooth muscle cells require beta1 integrin for survival. Following the induced deletion of smooth muscle beta1 integrin, smooth muscle cells undergo apoptosis and arteries become fibrotic. This microarray study on mesenteric arteries 2 weeks after the initiation of beta1 integrin deletion specifically in smooth muscle cells of the adult mouse aimed to examine early changes in expression following deletion. Mesenteric arteries from three wild type mixed background and three beta1 integrin smooth muscle knockout mixed background mice are examined.

Project description:Background: The vascular wall of small arteries is heavily affected by high blood pressure. However, the underlying mechanisms causing vascular changes are not fully elucidated. Using a novel data-independent acquisition mass spectrometry (DIA-MS) approach, we aimed to determine the proteomic changes in small mesenteric arteries during early-onset high blood pressure in a rat model of hypertension. Methods: Snap frozen small mesenteric and renal arteries from the spontaneous hypertension rat (SHR) model and Wistar Kyoto (WKY) control rats were collected from two time points (6- and 12-weels of age) and analyzed by a label free quantitative DIA-MS workflow. Mesenteric arteries from Wister Hannover rats were included as an additional control to clarify genetic drift caused by selective inbreeding. Results: We identified a total of 3956 consistent proteins in the mesenteric artery wall and found that 286 proteins were significantly regulated in 12-weeks old SHRs compared to WKY controls. Comparing to an in silico matrisome database, we identified 38 extracellular matrix-associated proteins that could distinguish SHRs from WKY controls. Furthermore, when comparing the significantly regulated proteins identified in mesenteric and renal arteries, we identified 18 proteins, including Serpina3l, Igg-2a, ENSRNOG00000049829, Acyp2, Enpp3, Lss, Acaa1a, Basp1, an isoform of Basp1, Flot1, Flot2, Gstt1, Nit1, Ppid, Ikbkap, Poglut3, P4ha2 and Usp15, that were changed in both vascular beds. These proteins were associated with vital cellular processes, such as dyslipidemia, protease inhibition, remodeling and generation of reactive oxygen species. Majority of the identified proteins and pathways were associated with hypertension, and mapping the underlying changes help understanding the pathological processes occurring in the arterial wall during early-onset hypertension. Conclusions: Our data provides an in-depth analysis of the proteomic architecture of the mesenteric and renal artery wall from SHRs and WKY control rats. We identified 18 novel candidate proteins that highlights critical changes in small arteries of the SHR.

Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 5,264 nuclei in mouse adult testis. This dataset includes two samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.

Project description:This is an investigation of whole genome gene expression level in tissues of mice stimulated by LPS, FK565 or LPS + FK565 in vivo and ex vivo. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in aortic root including aortic valves, slight in aorta and absent in other arteries. The degree of respective vascular inflammation is associated with persistent high expression of proinflammatory chemokine/cytokine genes in each tissue in vivo by microarray analysis, and not with Nod1 expression levels. The ex vivo production of proinflammatory chemokine/cytokine by Nod1 ligand is higher in aortic root than in other arteries from normal murine vascular tissues, and also higher in human coronary artery endothelial cells (HCAEC) than in human pulmonary artery endothelial cells (HPAEC), suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular tissue/cell itself.
