Presentation transcript:

Integrins modulate the Notch pathway by regulating its intracellular trafficking and/or processing. Integrins modulate the Notch pathway by regulating its intracellular trafficking and/or processing. Egg chambers were stained with anti-GFP (A–F; green), anti-FasIII (A,B; red), anti-NICD (C–F; red), anti-Hrs (E; green) and TO-PRO-3 (blue). Expression of NICD (A) but not full-length Notch (‘N’; B) restores the normal expression of FasIII and nuclear size of mys PFCs in ectopic layers (GFP−, arrow). (C) NICD expression in wild-type (wt) egg chambers (arrowhead). (D) mys PFCs located in ectopic layers (GFP−, arrow) contain discrete cytoplasmic and membrane-associated accumulations of NICD. (E) Some of the ectopic NICD is found to colocalize with Hrs (arrow). Note that mys PFCs in contact with the germline show normal NICD localization (GFP−, arrowhead in D). (F) However, reduction of Dl function in these mutant PFCs (arrowhead) leads to an accumulation of NICD similar to that found in mys PFCs in ectopic layers (arrow in D).
