Abstract
cDNA encoding mature human placental variant growth hormone (HGH-V) was synthesized by retro-transcription polymerase chain reaction (RT-PCR) from total RNA recovered from human term-placenta and cloned in pBluescript plasmid (pBS) in Escherichia coli. cDNA was subcloned into pPIC9, fusing it to the flanking regulatory sequences of the Pichia pastoris alcohol oxidase 1 gene (AOX1) and finally introduced into the genome of this yeast by homologous recombination. The resulting new recombinant strain produced and secreted, towards the culture medium, mature HGH-V, whose activity was demonstrated in cell culture by the Nb2 proliferation assay.
