1 Phospholipase A(2) antagonists inhibit nocodazole-induced Golgi ministack formation: evidence of an ER intermediate and constitutive cycling. Nocodazole phospholipase A2 group IB Rattus norvegicus
2 Here, we studied the nocodazole-induced formation of ministacks using phospholipase A(2) (PLA(2)) antagonists, which have been shown previously to inhibit brefeldin A-stimulated Golgi-to-ER retrograde transport. Nocodazole phospholipase A2 group IB Rattus norvegicus
3 Here, we studied the nocodazole-induced formation of ministacks using phospholipase A(2) (PLA(2)) antagonists, which have been shown previously to inhibit brefeldin A-stimulated Golgi-to-ER retrograde transport. Nocodazole phospholipase A2 group IB Rattus norvegicus
4 Examination of clone 9 rat hepatocytes by immunofluorescence and immunoelectron microscopy revealed that a subset of PLA(2) antagonists prevented nocodazole-induced ministack formation by inhibiting two different trafficking pathways for resident Golgi enzymes; at 25 microM, retrograde Golgi-to-ER transport was inhibited, whereas at 5 microM, Golgi-to-ER trafficking was permitted, but resident Golgi enzymes accumulated in the ER. Nocodazole phospholipase A2 group IB Rattus norvegicus
