Back to article: The primary cilium protein folliculin is part of the autophagy signaling pathway to regulate epithelial cell size in response to fluid flow

FIGURE 6: Shear-stress dependent recruitment of ATG16L1 to primary cilium is impaired in FLCN knockdown cells. HK2 cells were transfected with control siRNA (siCTRL) or with siRNA targeting FLCN (siFLCN). 72 h later, they were subjected to fluid flow for 4 days (shear 4D) or not (static 4D). (A) ATG16L1 and actin levels were analyzed by western blot. (B) Cells prone to fluid flow were fixed with methanol, labeled with DAPI, immunostained for ATG16L1 and ARL13B and then analyzed by fluorescence microscopy. Arrowhead indicates presence of ATG16L1 at the basal body. (C) ATG16L1 positive structures at basal body were quantified from experiments shown in (B). Scale bar = 10μm.
