Thyroid hormones (THs) play an important role in vertebrate development; however, the underlying mechanisms of their actions are still poorly understood. Zebrafish (Danio rerio) is an emerging vertebrate model system to study the roles of THs during development. In general, the response to THs relies on closely related proteins and mechanisms across(More)
The ability of glucocorticoids (GCs) to regulate cell proliferation plays an important role in their therapeutic use. The canonical Wnt pathway, which promotes the proliferation of many cancers and differentiated tissues, is an emerging target for the actions of GCs, albeit existing links between these signaling pathways are indirect. By screening known Wnt(More)
BAG-1 has been identified as a Bcl-2-binding protein that inhibits apoptosis, either alone or in co-operation with Bcl-2. Here we show that BAG-1 inhibits p53- induced apoptosis in the human tumour cell line Saos-2. In contrast, BAG-1 was unable to inhibit the p53-independent pathway induced by apoptin, an apoptosis-inducing protein derived from chicken(More)
Molecular chaperones have been reported as multifunctional antistress molecules that can regulate diverse biological processes to maintain cellular homeostasis. Molecular chaperones have critical roles for maintaining proper protein folding, protein translocation, degradation of unfolded protein, regulating signal-transduction proteins and so on. Under(More)
Transcription termination by RNA polymerase (Pol) II is an essential but poorly understood process. In eukaryotic nuclei, the 3' ends of mRNAs are generated by cleavage and polyadenylation, and the same sequence elements that specify that process are required for downstream release of the polymerase from the DNA. Although Pol II is known to bind proteins(More)
