Distinct mouse models of Stargardt disease display differences in pharmacological targeting of ceramides and inflammatory responses

ABSTRACT: We wanted to transcriptomically compare single cells taken from the retinas of C57BL6/J mice, Abca4-/-Rdh8-/- (dKO) mutant mice, and Abca4PV/PVRdh8-/- (PVR) mutant mice before and at an early (24-hour post-bleach) timepoint post-bleaching, to see if the two Abca4 mutants displayed different transcriptomic shifts in response to intense light, which initiates retinal degeneration. Additionally, we wanted to determine if the two mutants had different transcriptional responses to the immunomodulatory drug maraviroc. The wild-type C57BL6/J mice were included as controls for each treatment condition. We profiled the three cohorts of mice under three separate treatment conditions: without light-induced degeneration, 24-hours post-bleaching with intense light and vehicle treatment, and 24-hours post-bleaching with intense light and maraviroc treatment. Single cell isolates were collected, fixed, barcoded, and sequenced using kits from Parse Biosciences.

RNA-Seq of retina and RPE/choroid tissues from wild type, Abca4 knockout and Abca4 L541P;A1038V knockin mice

Project description:We report RNA-Seq analysis of the transcriptome of retinas and RPE/choroids from Abca4 knockout, Abca4 L541P;A1038V knockin and control wild type mice in order to better understand changes in gene regulation that could lead to retinal pathology in mice with ABCA4 deficiency/defect. Retinal and RPE/choroidal mRNA profiles of 30-day-old wild type (WT), Abca4-/- and Abca4L541P;A1038V/L541P;A1038V mice were generated by RNA-Seq, using Illumina Hiseq 2500

CD4+ T cell gene expression in virologically suppressed HIV-infected patients during Maraviroc intensification therapy.

Project description:Analysis of CD4+ T cell gene expression changes after 4 and 24 weeks of Maraviroc administration relative to baseline in 25 immunodiscordant patients with viral suppression. Maraviroc elicited very modest changes in CD4+ T cell transcriptome. The goal of this study was to identify genes with a potential role in Maraviroc-induced CD4+ T cell recovery in immunodiscordant patients. The study measured gene expression in CD4+ T cells isolated from the whole blood of HIV-infected patients before and at two time points after addition of Maraviroc to the baseline antiretroviral therapy. Thirty two patients were recruited from 3 sites, University of California, San Diego (UCSD), University of California, Los Angeles (UCLA) and University of Southern California (USC), and peripheral blood samples were obtained at 3 visits, week 0 (baseline), week 4 and week 24 after initiation of Maraviroc therapy. Because of poor RNA quality and outliers on the microarrays, 7 patients were excluded from the study. Non-outlier week 0 and week 24 arrays from one of the patients (Patient ID 01-005) were used for array data normalization and processing, but were not included in the time course analysis since the week 4 sample was not available.

Proteomics of coral susceptibility to bleaching

Project description:Twelve coral colonies of Montipora capitata were collected from patch reefs located in Kāne’ohe Bay, O’ahu, Hawai’i. Colonies were brought to shore where they were immediately split into two equally sized pieces, which were acclimated before bleaching. Half of each colony went to an increased water temperature treatment (30°C, bleaching treatment) and the other stayed at ambient temperature (25°C, nonbleached treatment) for three weeks. For the bleaching treatment, experimental tank temperatures were increased 2°C per day ( 1°C every 12 hours) for four days to a final temperature of 30°C. Samples were collected before bleaching (T1) and 24 hours after bleached colonies were returned to ambient temperature (T2), through 3 months post-bleaching (T6).

Daylight regulation of pulmonary gene expression in wild type mice

Project description:Daylight is fundamental to human health and is organ protective in a PER2 dependent manner. Using a whole genome array from daylight exposed wildtype mice, we investigated light elicited pathways. Mice were exposed to intense light (10,000 LUX, Lightbox simulating day light, Uplift Technologies DL930 Day-Light 10,000 Lux SAD, full spectrum) for 7 days and compared to mice maintained at room light [200 LUX]. Mice were housed in a 14/10-h light-dark cycle to synchronize (entrain) the circadian clock of mice to the ambient light-dark cycle.

mRNA-seq of C. elegans starved L1 progeny of parents fed empty vector, daf-2, or pitr-1 RNAi

Project description:hrde-1(tm1200) animals were bleached and embryos were plated on empty vector, daf-2, or pitr-1 RNAi (HT115). Animals were allowed to develop for 72 hr, after which embryos were released via bleaching and allowed to hatch in the absence of food. Arrested L1 larvae were snap frozen in liquid nitrogen ~24 hr after bleaching.

SM007 - Infection with SARS MA15 of C57BL6/J mice and CXCR3 knockouts in the same strain of mice

Project description:The purpose of this experiment is to compare the host response of C57BL6/J mice to that of CXCR3 knockout mutant mice in response to SARS MA15 virus infections. Groups of 10 week old C57BL6 mice or CXCR3 knockout mice were infected with SARS MA15 at a dose of 10^5 PFU or mock infected. Mice were euthanized on days 2, 4 and 7 post infection to measure virus load and isolate samples for measurement of virus load, lung pathology, and transcriptional. Mock infected animals were also harvested at each time point. Mice were weighed every 24 hours to measure general disease progression and any mouse approaching 30% weight loss were euthanized.
