these results strongly suggest that human hypothalamic grf derives from a precursor immunologically related ( and probably identical ) to the tumorous one and that this precursor is cleaved inside grf cell bodies to give , in addition to the grf-44-nh2 a second amidated peptide , the c-terminal pre-progrf that is transported distally to nerve endings and most probably coreleased with grf into portal capillaries .
