Single-minded 2 (SIM2) is a member of the bHLH-PAS family of transcription factors. SIM2 was initially identified by positional cloning on chromosome 21 and is thought to contribute to the etiology of trisomy-21 [Down syndrome (DS)]. In addition to the physical and mental deficiencies associated with this genetic disease, it has become apparent that women(More)
BACKGROUND An important component of time course microarray studies is the identification of genes that demonstrate significant time-dependent variation in their expression levels. Until recently, available methods for performing such significance tests required replicates of individual time points. This paper describes a replicate-free method that was(More)
Singleminded-2s (SIM2s) is a member of the bHLH/PAS family of transcription factors and a key regulator of mammary epithelial cell differentiation. SIM2s is highly expressed in mammary epithelial cells and downregulated in human breast cancer. Loss of Sim2s causes aberrant mouse mammary ductal development, with features suggestive of malignant(More)
