Protein kinase C activation and vacuolation in HeLa cells invaded by Mycoplasma penetrans

Protein kinase C activation and vacuolation in HeLa cells invaded by Mycoplasma penetrans.

The AIDS-associated Mycoplasma penetrans is capable of inducing its own uptake by non-phagocytic cells. This study investigated the invasion of HeLa cells and its consequences by confocal laser scanning microscopy. Invasion was dependent on the duration of infection and temperature, diminished by inhibiting microfilament assembly with cytochalasin D and almost completely abolished by disorganis...

Hemolytic and hemoxidative activities in Mycoplasma penetrans.

Mycoplasma penetrans is a newly isolated Mollicute from the urine of patients infected with human immunodeficiency virus that demonstrates the capacity to adhere to and invade human cells. A previous report, based on assays with mouse red blood cells (RBCs), indicated that M. penetrans lacked hemolytic activity. In our studies, we incubated different isolates of M. penetrans with various RBC sp...

berberine induced apoptosis of human osteosarcoma cells by inhibiting phosphoinositide 3 kinase/protein kinase b (pi3k/akt) signal pathway activation

background: osteosarcoma is a malignant tumor with high mortality but effective therapy has not yet been developed. berberine, an isoquinoline alkaloid component in several chinese herbs including huanglian, has been shown to induce growth inhibition and the apoptosis of certain cancer cells. the aim of this study was to determine the role of berberine on human osteosarcoma cell lines u2os and ...
