Table 2. Face–NPC center to center distance distributions for WT, Lmnb1^−/−, and Lmna^−/− MEFs.

Cell	Lamin	Observed (nm)		Expected (nm)		Observed − expected (nm)		P values		No. of NPCs

WT	LC	122.4	57.1	125.7	69.0	−3.3	−11.9	0.00		11,459
WT	LB1	118.3	56.8	129.1	76.0	−10.8	−19.2	0.00		15,150

Median and SD of the observed and expected lamin face to NPC distances, the difference between them, P values (see Materials and methods), and number of NPCs. The data in each row were collected from 10 cells. The Mann Whitney U test and Ansari-Bradley test were used as described in Materials and methods.

^aP values above the Bonferroni corrected α value of 0.05/7 tests = 0.007.
