Scorpion venom toxicity is of major concern due to its influence on human activities and public health. The cytotoxicity and apoptosis induced by scorpion L. quinquestriatus venom on two established eukaryotic cell lines (293T and C2C12) were analyzed. Both cultured cell lines were incubated with varying doses (10, 20, and 50 µg/ml) of scorpion venom in serum free medium (SFM) for 0.5, 1, 2, 4, and 8 hours at 37°C. The percentage of total lactate dehydrogenase (LDH) released in the culture during venom incubation was used as an index of cell damage. Control culture was treated with an equal amount of SFM. Cell injury was recognized morphologically and apoptosis was researched by a Fluorescing Apoptosis Detection System using the principle of TUNEL... |

We investigated the in vitro process of cell death caused by Egyptian cobra venom on primary human embryonic kidney (293T) and mouse myoblast (C2C12) cell lines. The aim of these studies was to provide further information about triggering cell death, and suggest methods for eliminating unwanted cells, such as tumour cells. Both cell lines were treated with 10, 20, and 50 m g/ml of Egyptian cobra (Naja haje) venom in serum free media (SFM) and incubated for 8 hours. Total activities of the lactate dehydrogenase (LDH) and creatine kinase (CK) released in the culture during venom incubation were used as an indicator of the venom in vitro cytotoxicity. Cell injury was morphologically recognized and apoptosis determined by a Fluorescing Apoptosis Detection... |
