Lentiviral infection of H9c2 and the selection of antibiotic-resistant cells resulted in a significant overexpression of LANCL1 (OVL1) or LANCL2 (OVL2) or both proteins (OVL1+2) in the double transfectants by approx. 15, 45 or 35 times, respectively, over control cells (PLV), transfected with the empty vector, as determined by Western blot (Figure 2A). Here, LANCL1 is linked to infection.
