LPL and diabetes mellitus: Finally, genes for which only one factor is explanatory are either responsive to diabetes only: Pla2g5, Lpl, Mmp1a, and Atoh8 fall into this group, or responsive to diet only: this subset is constituted by Ermp1, Tm9sf1, Frem1, Usp24, Adamts6, and Thbs2. Neither an interaction nor any of the single factors had significant explanatory value for expression levels of Csf2rb.
