In this report, we review our present effort in the field of molecular
reproductive endocrinology: to identify a small molecular weight foll
icle stimulating hormone (FSH) agonistic molecule. To achieve this goa
l we require a number of molecular tools, We have cloned and expressed
the human gonadotrophin, FSH and the human FSH receptor and developed
a reliable high throughput assay. We have also proposed a model to ex
plain FSH receptor activation and from that model, begun to create sma
ll molecules predicted to induce FSH signal transduction without bindi
ng to the extracellular domain of the membrane protein, In this report
, we summarize our efforts to date and discuss our future research eff
orts in this area.
