It has therefore long been assumed that the phenomenon is partly caused by stochastic events, in particular random fluctuations in gene expression, which must reach some threshold level to cause ...

CHEVY CHASE, Maryland, July 29, 2005 -- Random fluctuations in gene expression can influence the fates of cells infected with human immunodeficiency virus (HIV) far more than previously thought ...

Analyses of clonal cell populations have revealed fixed autosomal random monoallelic expression (aRME), in which allele-specific expression is conserved in daughter cells after division.
