If we extend the literature-based search so that we now include the first 200 gene probes recognized by GATHER then we have 27 gene probes associated with the Gene Ontology in terms of ''cell proliferation'' (p-value = 0.0002, Bayes Factor 5), and 'regulation of cell proliferation', p-value = 0.003, Bayes factor 3). However, other partners of PLK1 appear and their function in 'mitotic cell cycle' (pvalue = 0.0003, Bayes Factor 5) is increasingly present (in particular, the M phase of the mitotic cell cycle). The details of the Gene Ontology terms which are significant and the genes associated to them are listed in Table 2 .
