Genetic and biochemical approaches identify a new component of the cellular signaling machinery driving migration of limb muscle precursor cells during mouse embryogenesis and reveal the underlying molecular mechanism.
Inhibition of Polo-like kinase that has been shown to exhibit antitumor effect unexpectedly disrupts muscle stem cell function, leading to developmental and regenerative failures.
A set of ex vivo and in vivo experiments, including genetic ablation and regeneration studies, identify a key regulatory function of SOXF factors in muscle stem cells in mice.
RNA virus replication is attenuated by an intrinsic restriction mechanism after introducing CpG/UpA dinucleotides into both non-translated and coding regions of viral genomes, which may be exploited in the design of attenuated virus vaccines.
