We have established the gene for IGF binding protein 3 (IGFBP-3) as a target for FSH action. FSH effects on this gene require the PKA pathway as well as the PI-3 kinase and MAPK pathways. At the IGFBP-3 promoter, FSH effects depend on a site for TATA box binding protein (TBP) and formation of a high molecular weight transcription complex. To further elucidate FSH effects on the downstream events involving the TBP site, we cloned a pig TAF4b cDNA into a P-Flag expression vector. By co-transfecting granulosa cells with the IGFBP-3 promoter, we found that TAF4b mimics and enhances FSH induction of IGFBP-3 reporter activity. Using RT-PCR we showed that FSH stimulates expression of TAF4b. This would suggest that the role of TAF4b in follicular development is regulated by FSH. TAF4b may thus be the TFIID component that binds to the TBP site on the IGFBP-3 promoter and is essential for FSH induction of IGFBP-3.

In a mycological research performed in the Sjeverni Velebit National Park, Croatia, a new species of Coprotus was discovered, described here as C. epithecioides. Along with the microscopic examination, phylogenetic analysis of the type material, based on ITS and LSU sequences, was performed in order to evaluate its relationship with the type species, C. sexdecimsporus. The type species was sequenced in this study for the first time, providing ITS and LSU sequences from two separate collections which displayed differences in macroscopic characters and content of paraphyses. An extended description of C. sexdecimsporus based on Croatian material is also provided. A worldwide identification key to the species assigned to the genus Coprotus is presented, along with a species overview, containing a data matrix. The phylogenetic position of Coprotus in the Boubovia-Coprotus clade within Pyronemataceae s.l. is discussed. Coprotus sexdecimsporus is also reported here as new to the Croatian mycobiota.
