Polar bear (Ursus maritimus) hemoglobin (Hb) shows a low response to 2,3-diphosphoglycerate (2,3-DPG), compared to human Hb A0, even though these proteins have the same 2,3-DPG-binding site. In addition, polar bear Hb shows a high response to chloride and an alkaline Bohr effect (...
of ligand activation of human and polar bear PXRs.Polar bear PXR is a promiscuous ligand-activated nuclear receptor but less so than human PXR.Environmental contaminants activate human and polar bear PXRs differently.Expression and ligand promiscuity indicate that PXR is a xenosensor in polar bears...

As our samples date to the late 19th and early 20th century, the Suess effect on the δ13C values of the samples was minimal and approximated analytical error. Therefore, we compared our samples to archaeological datasets and did not correct the fur data for the Suess effect. However, ...
