abstractText | A 537 base pair cDNA clone for murine GIP has been isolated. The elucidated sequence encodes an open reading frame of 432 base pairs which codes for a 144 amino acid precursor. Murine GIP is predicted to differ from the human hormone by three amino acid substitutions: arginine for histidine at position 18, arginine for lysine at position 30 and serine for lysine at position 34. GIP mRNA levels in STC6-14 cells incubated in the presence of varying glucose concentrations was investigated using a competitive-PCR method. In the presence of a 5-mM glucose stimulus, 1 x 10(5) GIP cells were found to contain 3.9 +/- 0.59 amol of GIP mRNA while the same number of cells contained 11.6 +/- 1.4 amol when subjected to a high (25 mM) glucose stimulus. |
