Fig. 11. Treatment with LMB leads to an increase in the number of BR mRNP particles that are in transit through the NPCs. C. tentans larvae were treated with LMB and the salivary gland cells were analysed by electron microscopy. (A-D) Control cells without LMB. (A) BR mRNP particle docking at the NPC. (B-D) BR mRNP particles translocating through the NPC. (E-H) LMB-treated cells. (E) BR mRNP particle docking at the NPC. (F-H) BR mRNP particles translocating through the NPCs. Cyt, cytoplasm; Nu, nucleus. Bar, 100 nm.
