it is concluded that the postsecretory stability of peptides excised from the grp precursor in small cell lung cancer cells varies under tissue culture conditions , but epitopes in the c-terminal part of the precursor are more stable in plasma than the small grp peptides and , thus , may serve as a better indicator than grp itself for expression of the grp precursor in cancer cells .
