Certain Anura AMPs have been observed to express selective cytotoxicity against tumour cells, such as AMPs from African claw frogs from the Pipidae family which have demonstrated tumouricidal properties against small cell lung cancer cell lines [17] and bladder cancer cell lines [18] as well as a range of hematopoietic cell lines [19]. The gene discussed is ADSL; the disease is small cell lung carcinoma.
