HEK 293 cells cell, all of which are abundant in kidneys. However, the original adenovirus transformation was inefficient, suggesting that the cell that finally produced the HEK 293 line may have been unusual in some fashion. Graham and coworkers provided evidence that HEK 293 cells and other human cell lines generated by adenovirus transformation of human embryonic kidney cells have many properties of immature neurons, suggesting that the adenovirus preferentially transformed a neuronal lineage cell in the original kidney culture. A comprehensive study of the genomes and transcriptomes of HEK 293 and five derivative cell lines compared the HEK 293 transcriptome with that
How Are We to Live? the key for a satisfactory life resides on its purpose and how crucial for that purpose a commitment to an ethical life is. This connects with the argument that the pursuit of self-interest is self-defeating. He argues that altruism can be genuine - not just enlightened self-interest, and offers examples of people who sacrificed their lives to save people from Nazis to make this point. Singer comments on the effect of having the widest perspective possible on our ethical decisions; on how our rational capability sometimes leads us to change our goal; and on the paradoxical opportunity that the existence
