DAF-19, the only RFX transcription factor found in C. elegans, is required for the formation of neuronal sensory cilia. Four isoforms of the DAF-19 protein have been reported, and the m86 nonsense (null) mutation affecting all four isoforms has been shown to prevent cilia formation. Transcriptome analyses employing microarrays of L1 and adult stage worms were completed using RNA from daf-19(m86) worms and an isogenic wild type strain to identify additional putative DAF-19 target genes. Using transcriptional fusions with GFP, we compared the expression patterns of several potential gene targets using fluorescence confocal microscopy. Expression patterns were characterized in …

Fragile X Syndrome (FXS) is one of the most commonly inherited mental retardations. It is caused by the loss of functional fragile X mental retardation protein (FMRP). Loss of functional FMRP is the most widespread single-gene cause of autism. The most prominent phenotype of FXS patients is an IQ ranging from 20 to 70. FMRP is an RNA binding protein, widely expressed in almost all tissues and highly expressed in brain. As a RNA binding protein, 85-90 % of FMRP in the brain is associated with polyribosomes. Approximately 4 % of total mRNA is associated with FMRP, which functions in …
