Nystagmus in the B6(CG)Tyr(c-2J)/J Albino Mouse: A Functional and RNAseq Analysis

ABSTRACT: PURPOSE: Infantile nystagmus syndrome (INS) is a gaze-holding disorder characterized by conjugate, uncontrolled eye oscillations that can result in significant visual acuity loss. INS is often associated with albinism, but the mechanism is unclear. Albino mice have nystagmus; however, a pigmented mouse with a tyr mutation making it phenotypically albino, the B6(CG)-Tyr(c-2J)/J (B6 albino), had not been tested. We tested optokinetic nystagmus reflexes (OKN) in B6 albino and control mice. RNA-Seq was performed on extraocular muscles (EOM), tibialis anterior muscle (TA), abducens (CN6), and oculomotor (CN3) neurons to uncover molecular differences that could account for nystagmus.

Expression data from retinal pigment epithelium in pigmented and albino mouse embryos

Project description:In mammalian albinism, disrupted melanogenesis in the retinal pigment epithelium (RPE) is associated with fewer retinal ganglion cells (RGCs) projecting ipsilaterally to the brain, resulting in numerous abnormalities in the retina and visual pathway, especially binocular vision. To further understand the molecular link between disrupted RPE and a reduced ipsilateral RGC projection in albinism, we compared gene expression in the embryonic albino and pigmented mouse RPE.

Pseudo-albino or pigmented Solea senegalensis (Senegalese sole) anterior gut and dorsal skin transcriptomes (RNA-seq), raw sequence reads

Project description:Pseudo-albinism is a complex condition, caused by a multitude of factors and negatively affecting flatfish aquaculture. The majority of studies have targeted genes involved in pigmentation, the most notable change in these animals. In this study, a global transcriptome approach was taken to understand the underlying basis of Senegalese sole pseudo-albinism, using as targets two important innate immune barriers, the skin and intestine. RNA-seq transcriptome analysis identified 573 differentially expressed transcripts (DETs) between pseudo-albino and pigmented soles in the skin and/or the gut. DETs were mainly linked to pigment production, skin structure and regeneration, mucus production and smooth muscle contraction.

Microarray analysis of iris gene expression in mice with mutations relevant to glaucoma

Project description:Several ocular diseases involve the iris, notably including oculocutaneous albinism, pigment dispersion syndrome, and exfoliation syndrome. To screen for candidate genes that may be active in these diseases, genome-wide iris gene expression patterns were comparatively analyzed from mouse models of these conditions. Irides were obtained from healthy C57Bl/6J, B6-Lystbg-J/J which carry a mutation in the Lyst gene, B6(Cg)-TyrC-2J/J which carry a mutation in the tyr gene, and B6.D2-Tryp1bGpnmbR150X/Sj with mutations in both Tryp1 and Gpnmb. Four eyes from two mice were pooled for one sample. Three samples were prepared for each strain.

Proteome of Agave angustifolia Haw.: insights about metabolism of amino acids in albino plantlets

Project description:Amino acids (AA) are essential molecules for life because they are precursors for the synthesis of proteins and other organic compounds. Their metabolism in plants involves more than one cellular compartment, among which the chloroplast plays a key role. From the 20 essential AA, ten (Arg, Lys, Thr, Leu, Ile, Val, Trp, Phe, Tyr and His) are only synthesized in the plastids and seven (Asp, Cys, Gln, Glu, Gly, Ser and Met) can be synthesized in both chloroplast and other parts of the cell. Despite knowing the roles of AA in plant physiology, little has been assessed in plants with albino phenotypes, lacking chloroplasts. To assess the effect of chloroplast biogenesis disturbances on AA metabolism in albino and variegated somaclonal variations of Agave angustifolia Haw., a comparative proteomic based TMT- synchronous precursor selection (SPS)-MS3 strategy was used to determine the status of AA biosynthetic pathways. Besides the 20 essential AA was quantified to underpin proteomics finding. A total of 2,442 different proteins were identified in the proteome of the somaclonal variants, from which 82 correspond to enzymes participating in AA biosynthesis. From these 82, 32 proteins were differentially accumulated. On the other hand, the concentration of 16 and 12 of the AA synthesized by the chloroplast were over-accumulated in the variegated and albino somaclonal variant, respectively. In plantlets devoid of functional chloroplasts, there is a surprising increase of AA and key enzymes of the AA biosyntethic pathways, compared to green plantlets. This could suggest que la activation of AA biosynthesis is key to sustaining albino and variegated plantlets survival that lack chloroplasts.

Transcription profiling of Arabidopsis albino mutant DS 13-2198-1

Project description:The effect Ds insertion mutation in Ds13-2198-1 line on the gene expression profiles was investigated. The genes for photosynthesis and some transcriptional factors were upregulated while genes for metabolism were downregulated. Experiment Overall Design: To investigate the effect of an strong albino mutation, the genome wide gene expression profiles of plants were examined. Segregants with normal phenotype and albino phenotype obtained from the heterotalic parental line were grown on the same 1/2 MS plate for 3 weeks.
