Besides the overall "inconspicuous" expression behaviour of imprinted genes we observe particular expression patterns of subsets of imprinted genes in certain human and mouse tissues.
Perhaps most interesting is the functional behaviour of a subset of the bidirectional promoters in the presence of TORC1.
With the emergence of two monocyte subsets, a multistep model would envision that the relative surface expression of adhesion molecules and chemokine receptors determines the recruitment behaviour of each subset.
The behaviour of T cell subsets bearing adhesion molecules was noteworthy.
This crawling behaviour is reminiscent of 'patrolling' behaviour reported for a subset of blood monocytes in mice that respond to microbial infection (Auffray et al., 2007).
Several studies showed a distinct biological behaviour of the HPV-positive subset of oropharyngeal tumours, resulting in a more favourable prognosis (Li et al, 2003).
This is suggestive of differences in the biological behaviour of tumours in this subset of melanoma patients and might in part explain the differences in outcome in the two studies.
Why does the self-stimulation of dopamine neurons lead to compulsive behaviour in only a subset of individuals?
Instead, health behaviours are identified as the ultimate outcome of interest, with health services utilization and personal health choices included as subsets of health behaviours.
The different subsets of HG have different behaviours (Supplementary Note 1) and risks of false positives and negatives (Supplementary Note 2).
