The effects of LP-CC6, LP-CC24 and CisPt on tumour cells were investigated by real-time PCR (qPCR) by evaluating the expression of the TP53 gene that encodes a tumour suppressor protein, the pro-apoptotic BAX gene and the BCL2 gene, which encodes an integral outer mitochondrial membrane protein that blocks the apoptotic death of some cells, such as lymphocytes. This evidence concerns the gene TP53 and neoplasm.
