Gene Expression Signatures In Tree Shrew Sclera In Different Visual Conditions, Lin Guo
Gene Expression Signatures In Tree Shrew Sclera In Different Visual Conditions, Lin Guo
All ETDs from UAB
The sclera is a target tissue that receives signals that are initiated in the retina, cascade through retinal pigment epithelium (RPE) and choroid, and cause scleral extra cellular matrix remodeling. Biomechanical alterations of the sclera are produced by these biochemical changes, and in turn control the axial length of the eye. This dissertation project examined scleral gene expression changes in mRNA level of juvenile tree shrews. Three specific aims were investigated: specific aim one tested the hypothesis that three different GO visual conditions that all produce axial elongation and myopia: minus-lens wear, form deprivation, and continuous darkness, will produce similar …
Gene Expression Signatures In Tree Shrew Retina, Rpe, And Choroid During Experimental Myopia And Recovery, Li He
All ETDs from UAB
During the development of induced myopia and recovery, the emmetropization mechanism is stimulated to modulate ocular growth. Emmetropization signals originate in the retina, are transmitted and transformed by retinal pigment epithelium (RPE) and choroid, and reach sclera to induce tissue remodeling. Induced myopia occurs in response to myopiagenic stimuli - minus lens, form deprivation, and darkness - (three GO conditions) which increase ocular elongation; recovery from lens-induced myopia (STOP) occurs when minus-lens wear is discontinued after complete compensation, slowing ocular elongation. This dissertation examined gene expression signatures in the retina, RPE, and choroid under GO and STOP conditions to examine …

Coexisting lesions can reduce genomic heterogeneity in precancer progression analysis by reducing variation and bias that can mask gene effects. Our goal was to use novel methodologies to depict the neoplastic stage effect (Normal v. LSIL v. HSIL) in cervical precancer. We analyzed the neoplastic stage effect via in silico and in vivo methodologies. For in silico analyses, we calculated differential expression (DE) estimates from a systematic review of DNA methylation and gene expression literature. Significant genes (FC≤2.0 or p-value≥0.05) were grouped by histology for pathway analysis. For in vivo analyses, we performed RNA-seq on microdissected FFPE coexisting cervical tissue …
