Project description:A control vs. genetic knockout experiment aimed at determining what RNAs are upregulated or downregulated in e11.5 mouse proximal limb tissue lacking the Lmx1b gene. Because Lmx1b is required for dorsal-ventral patterning of the limb, this screen gives insight into what putative downstream targets of Lmx1b contribute to dorsal-ventral patterning. Experiment Overall Design: The proximal portion of e11.5 hindlimb buds (~500um) was used for RNA extraction. Each array was hybridized with pooled cRNAs from both hindlimb buds of three embryos (6 hindlimbs/sample).
Project description:A control vs. genetic knockout experiment aimed at determining what RNAs are upregulated or downregulated in E13.5 mouse limb tissue lacking the Lmx1b gene. Because LMX1B is required for dorsal-ventral patterning of the limb, this screen gives insight into what putative downstream targets of Lmx1b contribute to dorsal-ventral patterning. The forelimb or hindlimb of wild-type controls or Lmx1b loss-of-function mutants was used for RNA extraction. Each array was hybridized with cDNAs of an individual limb.
