TJ411(fer-15(b26)II; age-1(hx542)II) vs. BA713(fer-15(b26)II)


ABSTRACT: To identify changes in gene expression in age-1 mutants, we compared expression in fer-15(b26) animals to expression in fer-15(b26); age-1(hx542) mutants. We prepared RNA from young adult fer-15(b26) mutants grown at 25?C (five samples prepared at Stanford University and six samples prepared at the University of Colorado) and young adult fer-15(b26); age-1(hx542) mutants (four samples at Stanford University and six samples at the University of Colorado). Set of arrays that are part of repeated experiments Place of growth: Stanford vs Colorado Genotype: mutant strains vs wt (N2) mixed stage; some expts are reverse dye Biological Replicate Computed

To define the C. elegans aging process at the molecular level, we used DNA microarray experiments to identify a set of 1294 age-regulated genes and found that the GATA transcription factors ELT-3, ELT-5, and ELT-6 are responsible for age regulation of a large fraction of these genes. Expression of elt-5 and elt-6 increases during normal aging, and both of these GATA factors repress expression of elt-3, which shows a corresponding decrease in expression in old worms. elt-3 regulates a large numbe  ...[more]
