View SamplesPhotoreceptor degeneration is the central event leading to visual impairment or blindness in most retinal diseases. However, the discovery of safe and effective therapeutic strategies conferring photoreceptor protection remains challenging. A systems pharmacology approach, synergistically targeting distinct cellular pathways could provide an effective strategy for evaluating, preventing or treating retinal dystrophies. Here this concept was investigated using a mouse model of light-induced retinal degeneration. We show that a combination of FDA-approved drugs acting on different G protein-coupled receptors in a synergistic manner could protect retinas against light-induced degeneration when each drug in the combination treatment was administered at a sub-therapeutic dose. Furthermore, transcriptome analyses demonstrated that such combined treatments also preserved patterns of retinal gene expression more characteristic of the normal retina than did single therapies at higher doses. The current study thus supports a new systems pharmacology approach that may extend to other complex neurodegenerative disorders in addition to retinal diseases. Overall design: Male and female Abca4-/-Rdh8-/- at the age of 4- to 6-weeks were used for the current study. All mice were housed and maintained in a 12 h light (=10 lux)/12 h dark cyclic environment in the Animal Resource Center at the School of Medicine, Case Western Reserve University (CWRU). Bright light-induced retinal damage was generated by exposing Abca4-/-Rdh8-/- mice to white light delivered at 10,000 lux (150 W spiral lamp, Commercial Electric) for 30 min. All indicated treatments were administered by intraperitoneal injection 30 min prior to bright light exposure and retinas collected one day later. Single compounds and their tested doses were: 2-Bromo-a-ergocryptine methanesulfonate salt (BRM), metoprolol tartrate (MTP), tamsulosin (TAM), and doxazosin (DOX). Combined treatments were: BRM, MTP and TAM (BMT), or MTP, DOX, and BRM (MDB).

View SamplesWe 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. Overall design: 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

View SamplesExpression of DREAM in dorsal root ganglia and spinal cord is related to endogenous control mechanisms of acute and chronic pain. In primary sensory trigeminal neurons high levels of endogenous DREAM protein are preferentially localized in the nucleus, suggesting a major transcriptional role. Here, we show that DREAM participates in the control of trigeminal pain perception through the regulation of prodynorphin and BDNF. Furthermore, genome-wide analysis of trigeminal neurons in daDREAM transgenic mice revealed that cathepsin L (CTSL) and the monoglyceride lipase (MGLL) are new DREAM downstream targets and have a role in the regulation of trigeminal nociception.
Transcriptional repressor DREAM regulates trigeminal noxious perception.
