Transcription profiling of skeletal muscle from wild type and Nebulin knock-out mice


ABSTRACT: Knock out of the Nebulin gene. We compared the Quadriceps of two Nebulin -deficient vs. 2 Wildtype mice. The two KO-WT pairs derived from two litters (F2 generation, background: C57/Bl6 and 129/IB10).

The precise assembly of the highly organized filament systems found in muscle is critically important for its function. It has been hypothesized that nebulin, a giant filamentous protein extending along the entire length of the thin filament, provides a blueprint for muscle thin filament assembly. To test this hypothesis, we generated a KO mouse model to investigate nebulin functions in vivo. Nebulin KO mice assemble thin filaments of reduced lengths and approximately 15% of their Z-disks are ab  ...[more]
