Isolation and partial characterization of basic fibroblast growth factor from bovine testis
Molecular and Cellular Endocrinology
|February 1, 1987
Summary
Basic fibroblast growth factor (FGF) was purified from bovine testis. This testicular FGF exhibits biological activity, suggesting a role in regulating testicular function and spermatogenesis.
Area of Science:
- Biochemistry
- Molecular Biology
- Reproductive Biology
Background:
- Basic fibroblast growth factor (FGF) is a key signaling molecule involved in various cellular processes.
- The presence and function of FGF in the testis have not been fully elucidated.
Purpose of the Study:
- To purify and characterize basic FGF from bovine testis.
- To investigate the biological activity and potential role of testicular FGF.
Main Methods:
- Purification using ammonium sulfate precipitation and multiple chromatographic techniques (cation-exchange, heparin-Sepharose, reversed-phase HPLC).
- Amino-terminal amino acid sequencing via gas-phase analysis.
- Assessment of biological activity.
Main Results:
- Basic FGF was successfully purified to homogeneity from bovine testis.
- The amino-terminal sequence matched previously identified FGF fragments.
- The purified testicular FGF demonstrated biological activity comparable to known basic FGF.
Conclusions:
- Basic FGF is present in the bovine testis.
- Testicular FGF may function as a local regulator of testicular activity.
- FGF likely plays a significant role in spermatogenesis and testicular development.
