Figure 5. IGF1R inhibition alters the expression level of BICD1.

Figure 5

  1. Western blot of PMN treated with 1 μM PPP or 50 ng/ml IGF1 for 60 min. Cells were lysed and the extracts assessed for expression levels of dynein adaptor proteins, all proteins were assessed from the same blot.
  2. Hook3 expression did not change after treatment with PPP or IGF1 compared to controls (DMSO, 100%; PPP, 102.16 ± 4.3%, P = 0.67, Student's t‐test, N = 3 independent experiments; water, 100%; IGF1, 93.48 ± 4.2%, P = 0.26, N = 3 independent experiments; data shown are mean ± SEM).
  3. However, BICD1 expression was significantly increased in PMN treated with PPP compared to control (DMSO, 100%; PPP, 137.1 ± 7.3%, **P = 0.002, Student's t‐test, N = 7 independent experiments). In contrast, IGF1R stimulation by IGF1 had no effect on BICD1 expression (water, 100%; IGF1, 88.1 ± 14.0%, P = 0.49, Student's t‐test, N = 3 independent experiments; data shown are mean ± SEM).
  4. BICD2 expression did not change after treatment with PPP or IGF1 compared to controls (DMSO, 100%; PPP, 104.44 ± 6.5%, P = 0.51, N = 3 independent experiments: water, 100%; IGF1, 106 ± 7.5%, P = 0.51, Student's t‐test, N = 3 independent experiments; data shown are mean ± SEM).
