A bioinformatics process which provides an improved means to detect NFkB cellular signaling pathway in a subject, such as a human, based on the expression levels of at least six unique target genes of the NFkB cellular signaling pathway measured in a sample. The invention includes an apparatus comprising a digital processor configured to perform such a method, a non-transitory storage medium storing instructions that are executable by a digital processing device to perform such a method, and a computer program comprising program code means for causing a digital processing device to perform such a method. Kits are also provided for measuring expression levels of unique sets of NFkB cellular signaling pathway target genes.
