Transcription profiling of cultured human cells response to stress (heat shock)
Ontology highlight
ABSTRACT: TT3 and TN are cell cycle time courses and should be centered or transformed before clustering or computing fourier scores. The preferred method is SVD centering preceded by KNNImpute missing-value estimation, although mean-centering is a viable alternative. Hela Heat 42 degrees time course has 2 zeroes (the second is labeled "Cold 25 degrees 0h"). Normalization is by centering or zero transformation (average 2 zeroes) WI38 Crowding (1-3 days) was by plating cells at ~50%? confluence and allowing to age. The zeroes are the same as for WI38 Heat Shock (there are 2) Other time courses should be self-explanatory. They have 1-4 zeroes each and can be treated either by centering or zero-transforming. WI38
