Caveolin-1 is transported to multi-vesicular bodies after albumin-induced endocytosis of caveolae in HepG2 cells

Caveolae-mediated endocytosis is a highly regulated endocytic pathway that exists in parallel to other forms of clathrin-dependent and -independent endocytosis. Internalized caveolae accumulate in intermediate organelles called caveosomes. Here we addressed the further fate of internalized caveolae by inducing caveolae-mediated uptake of albumin by HepG2 cells. We followed the route of internal...

Clathrin- and caveolin-1–independent endocytosis: entry of simian virus 40 into cells devoid of caveolae

imian Virus 40 (SV40) has been shown to enter host cells by caveolar endocytosis followed by transport via caveosomes to the endoplasmic reticulum (ER). Using a caveolin-1 (cav-1)–deficient cell line (human hepatoma 7) and embryonic fibroblasts from a cav-1 knockout mouse, we found that in the absence of caveolae, but also in wild-type embryonic fibroblasts, the virus exploits an alternative, c...

[Letter to the Editor] DNA Fragmentation Is Not Associated with Apoptosis in Zerumbone-induced HepG2 Cells

Zerumbone is a cytotoxic compound isolated from the herbal plant, Zingiber zerumbet Smith, which exhibits antitumor activity [1-2], anti-inflammatory effects and possesses anti-proliferative potentials in a variety of cell lines [3-4]. DNA fragmentation indicates an early event of apoptosis leading to cell death due to the absence of new cellular proteins synthesizing for cell survival. Previou...

Caveolin-1, caveolae, and glioblastoma.

Glioblastoma multiforme (GBM) is the most common malignant brain tumor and is characterized by high invasiveness, poor prognosis, and limited therapeutic options. Biochemical and morphological experiments have shown the presence of caveolae in glioblastoma cells. Caveolae are flask-shaped plasma membrane subdomains that play trafficking, mechanosensing, and signaling roles. Caveolin-1 is a memb...

Human podocytes perform polarized, caveolae-dependent albumin endocytosis.

The renal glomerulus forms a selective filtration barrier that allows the passage of water, ions, and small solutes into the urinary space while restricting the passage of cells and macromolecules. The three layers of the glomerular filtration barrier include the vascular endothelium, glomerular basement membrane (GBM), and podocyte epithelium. Podocytes are capable of internalizing albumin and...
