| T1 |
0-111 |
Sentence |
denotes |
Human growth hormone (GH)-releasing factor stimulates and somatostatin inhibits the release of rat GH variants. |
| T2 |
112-391 |
Sentence |
denotes |
Two-dimensional polyacrylamide gel electrophoresis (2D PAGE) was used for the analysis of proteins secreted by male rat pituitary cells in monolayer culture in the presence of 10 nM human GH-releasing factor (hGRF) or 30 nM somatostatin (SRIF) or in the absence of these factors. |
| T3 |
392-511 |
Sentence |
denotes |
More than 300 medium proteins were reproducibly detected either by fluorographic autoradiography or by silver staining. |
| T4 |
512-669 |
Sentence |
denotes |
Immunoreactivity of each protein was examined after 2D PAGE followed by Western blotting and immunostaining with affinity-purified antirat GH (rGH) antibody. |
| T5 |
670-837 |
Sentence |
denotes |
While there was a cluster of immunoreactive spots in the GH dimer range (40,000-50,000 mol wt), at least 16 medium proteins of mol wt 22,000 or less were also stained. |
| T6 |
838-962 |
Sentence |
denotes |
Among these 16 proteins the release of 15 was stimulated and the release of 14 was inhibited by hGRF and SRIF, respectively. |
| T7 |
963-1176 |
Sentence |
denotes |
On the other hand, there were 3 proteins of approximate mol wt 16,000 whose secretion was regulated in a coordinate manner as rGH by the hypothalamic factors but which did not cross-react with anti-rGH antibodies. |
| T8 |
1177-1374 |
Sentence |
denotes |
The increase or decrease in the radioactivity of each protein spot obtained from media after pituitary cells were incubated with [35S]methionine and hypothalamic factors was analyzed statistically. |
| T9 |
1375-1504 |
Sentence |
denotes |
A pulse-chase study suggested that at least 7 of the hormonally regulated proteins, including rGH, were synthesized very rapidly. |
| T10 |
1505-1713 |
Sentence |
denotes |
Finally, the 2D PAGE analysis of cell-free translation products of messenger RNA derived from male rat anterior pituitaries revealed the presence of about 40 rGH-immunoreactive proteins which included pre-GH. |
| T11 |
1714-1803 |
Sentence |
denotes |
These data suggest that there are multiple forms of rGH-variants or rGH-related proteins. |
| T12 |
1804-1944 |
Sentence |
denotes |
The biological significance(s) of all the rGH immunoreactive proteins and of the GRF- and SRIF-regulated pituitary proteins remains unclear. |
| T13 |
1945-2058 |
Sentence |
denotes |
It is evident that a number of these proteins are synthesized and released rapidly by pituitary cells in culture. |
| T14 |
2059-2282 |
Sentence |
denotes |
Furthermore, the presence of multiple genes for these rGH-related proteins is suggested by the large family of immunoreactive gene products identified after cell-free translation of messenger RNA derived from the pituitary. |
