    Alternatively, we suggest using this opportunity to take a little break from work and read some of the interesting articles below. A long-standing paradigm in cell biology is the shutdown of endocytosis during mitosis.

    Effect of chloroquine treatment on GM1 level in PC12 cells. A PC12 cells were treated with chloroquine at the indicated concentrations for various durations. The lysates of treated cells were electrophoresed. The blots were reacted with CTB-HRP. B PC12 cells were treated with chloroquine at the indicated concentrations for 12 h. For instance, EIPA amiloride is a known inhibitor of macropinocytosis and other pathways, such as ICAM-and PECAM-mediated endocytosis. 58 However, these latter pathways are unlikely to play a. We report that AAK1 and the WNT co-receptor LRP6 physically co-complex and that AAK1 promotes clathrin-mediated endocytosis of LRP6. Collectively, our data support a WNT-induced negative feedback loop mediated by AAK1-driven, clathrin-mediated endocytosis of LRP6.

    A recent study proposed that endocytosis is continuous throughout the cell cycle and that the observed inhibition of transferrin uptake is due to a decrease in available transferrin receptor at the cell surface, and not to a shutdown of endocytosis. There is consensus that transferrin uptake is inhibited after entry into prophase and that it resumes in telophase.

  5. CD inhibits clathrin-dependent endocytosis by selectively extracting cholesterol from the plasma membrane. Hydrophobic amines such as phenothiazines, MDC and chloroquine inhibit clathrin-dependent endocytosis by affecting the function of clathrin and clathrin-coated vesicles Salisbury et al. 1980; Wang et al. 1993.

    Dec 22, 2006 Endocytic pathway abnormalities were previously observed in brains affected with Alzheimer’s disease AD. To clarify the pathological relevance of these abnormalities to assembly of amyloid β-protein Aβ, we treated PC12 cells with chloroquine, which potently perturbs membrane trafficking from endosomes to lysosomes. Ikarugamycin inhibits clathrinmediated endocytosis. A A semi‐log plot of the effect of increasing concentrations of IKA on TfnR uptake in H1299 cells. IKA has an IC 50 value of 2.7 μ m ± 0.3. B Effect of IKA on Tfn uptake in several different cell lines. The indicated cells were preincubated with 4 μ m IKA before uptake of TfnR was. Clathrin-mediated endocytosis CME is important for diverse processes such as cell signaling, nutrient uptake, and cell motility. Receptors destined for CME become concentrated in clathrin-coated pits at the cell surface where they bind to adaptor proteins and, hence, clathrin via specific endocytic motifs present in their cytoplasmic tails 2.
