The model was tested in two different human cell lines: MCF-7, an estrogen responsive cell line derived from metastatic human breast adenocarcinoma, which is known to express PTGS2 (12), and HEK293FT, a highly transfectable clonal isolate derived from human embryonal kidney cells HEK293, which does not constitutively express PTGS2 (13).

However, if the gene encoding my transcription factor, which should exist in the cDNA library, is fused to the gene encoding the GAL4 activation domain, which is made to be constitutively active, my factor should become constitutively active in a yeast strain regardless of the presence or absence of ER stress.

But the Ellis Island we encounter in Keith's study is less a port of access to an exceptional state than a place of imprisonment and expulsion, a symbol for how 'the process of becoming American is inextricably linked to the condition of unbecoming American' given that 'the universalism of American citizenship is constitutively linked to the production of subjects excluded from national membership' (p.
