MARINA (Master Regulator Inference Algorithm) MAster Regulator INference algorithm (MARINa), designed to infer transcription factors (TFs) controlling the transition between the two phenotypes, A and B, and the maintenance of the latter phenotype. Expression at the mRNA level is often a poor predictor of a TF's regulatory activity and an even worst predictor of its biological relevance in regulating phenotype-specific programs. To obviate this problem, MARINa infers TF activity from the global transcriptional activation of its regulon (i.e. its activated and repressed targets) and its biological relevance by TF-regulon overlap with phenotype-specific programs.
