Gene profiling studies in postnatal Mfrprd6 mutant eyes reveal differential expression of Prss56, a trypsin-like serine protease, and genes involved in visual and phototransduction pathways.

ABSTRACT: Mutations in the membrane frizzled-related gene (Mfrp) are linked to posterior microphthalmia, retinitis pigmentosa and nanophthalmia in humans. In homozygous Mfrprd6 mice, a splice site mutation causes a slow photoreceptor degeneration characterized by shortening and disorganization of outer segments with eventual photoreceptor loss. To better understand the function of MFRP in the retina, microarray analysis was carried out in mutant and control mice at postnatal day14 (P14), prior to the loss of photoreceptors. Analysis of the data revealed differentially expressed RPE and neuroretina transcripts. Although the analysis of the microarray data from Mfrprd6 mutant mice compared to age-matched wild-type controls identified some transcripts with relative fold change > 5.0, most of the dif
