Next generation sequencing facilitates quantitative analysis of retinal transcriptomes under normal light and high-intensity light condition

Project description:Photoreceptor cell degeneration is a major cause of blindness and a considerable health burden during aging but effective therapeutic or preventive strategies have not so far become commercially available. Here we show in mouse models that signaling through the tyrosine kinase receptor KIT protects photoreceptor cells against both light-induced and inherited retinal degeneration. Upon light damage, photoreceptor cells upregulate Kit ligand (KITL) and activate KIT signaling, which in turn induces nuclear accumulation of the transcription factor NRF2 and stimulates the expression of the antioxidant gene Hmox1. Conversely, a viable Kit mutation promotes light-induced photoreceptor damage, which is reversed by experimental expression of Hmox1. Furthermore, overexpression of KITL from a viral AAV8 vector prevents photoreceptor cell death and partially restores retinal function after light damage or in genetic models of human retinitis pigmentosa. Hence, application of KITL may provide a novel therapeutic avenue for prevention or treatment of retinal degeneration

Retinal light damage microarray

Project description:Microarray analysis of murine retinal light damage reveals changes in iron regulatory, complement, and antioxidant genes in the neurosensory retina and isolated retinal pigment epithelium (RPE). With the advent of microarrays representing most of the transcriptome and techniques to obtain RNA from the isolated RPE monolayer, we have probed the response of the RPE and neurosensory retina (NSR) to light damage. Mice were exposed to 10,000 lux cool white fluorescent light for 18 hours and sacrificed 4 hours after photic injury. NSR and isolated RPE were collected, and RNA was isolated. DNA microarray hybridization was conducted as described in the Affymetrix GeneChip Expression Analysis Technical Manual. Microarray analysis was performed using probe intensity data derived from the Mouse Gene 1.0 ST Array. For the genes of interest, confirmation of gene expression was done using quantitative real-time PCR. Immunofluorescence assessed protein levels and localization.

Expression profile of R. capsulatus by entering light after a dark period; and by high light intensity

Project description:The effects of low and high light intensities on transcriptome of purple non sulfur bacterium R. capsulatus were investigated by comparing expression profiles of dark and low light intensity (2000 lux), and by comparing high light intensity (10,000 lux) with low light intensity (2000 lux).

Transcription profiling of Arabidopsis acclimation to light intensity

Project description:The acclimation of plants to environmental factors (light/temperature/nutrient availability) plays a crucial role in determining their tolerance to stress their ability to compete with other plants and the efficiency with which external inputs are used for growth and productivity. Some of the clearest responses involve the major modifications in the composition of the photosynthetic apparatus in response to light intensity. Photosynthetic acclimation. The acclimation response involves changes in the abundance of a large number of proteins in different cell compartments occurring at different intensity thresholds. The signal transduction chain is complex and involves crosstalk between redox control and other pathways that control photosynthetic gene expression but is poorly understood. Over the past 7 years we have laid the foundations for a molecular genetic approach by characterising the responses of Arabidopsis thaliana to growth in and transfer between high and low light conditions(1-6). Arabidopsis exhibits all the key features of photosynthetic acclimation: changes in maximum photosynthetic rate in leaf structure and in the levels of light-harvesting complexes photosystems and enzymes of carbon metabolism. Method: Samples A-1, A-2 and A-3 were grown at a light intensity of 400 umol.m-2.s-1 until rosette growth was complete. Plants for samples A-2 and A-3 were then transferred to 100 umol.m-2.s-1. Samples A-4, A-5 and A-6 were grown at 100umol.m-2.s-1 until rosette growth was complete, when plants for samples A-5 and A-6 were transferred to 400 umol.m-2.s-1. Samples were taken 24 hours after transfer to the different light intensity and samples A-3 and A-6 were taken 72 hours after transfer. Keywords: Photosynthesis

RNA-seq of microalga Dunaliella tertiolecta determine growth-switch genes in response to higher light intensity

Project description:Purpose: Determine rate-limiting genes in response to higher light intensity Method: Cell division was observed at 8 h but not 4 h post light shift. The transcriptome of 4 h and 8 h post light shift were compared using RNA-seq. The reference transcriptome used was Dt-v10 (GEO accession no. GSE70876) Results and Conclusions: Genes belonging TCA cycle and amino acid syntheses increased later at 8 h, suggesting that they are the rate-limiting in the response to higher light intensity
