Abstract:
... During DNA replication, proliferating cell nuclear antigen (PCNA) adopts a ring-shaped structure to promote processive DNA synthesis, acting as a sliding clamp for polymerases. Known posttranslational modifications function at the outer surface of the PCNA ring to favor DNA damage bypass. Here, we demonstrate that acetylation of lysine residues at the inner surface of PCNA is induced by DNA lesion ...

Abstract:
... The environmental Kuznets curve hypothesis suggests that at high income levels, economic growth is accompanied by decreasing concentrations of air pollutants. We examine the relationship between four common air pollutants and income across Canadian provinces and metropolitan areas. Our study improves upon past studies of the relationship in Canada in two ways. First, our use of panel methods and p ...

The effects of ANQ on cancer stem cell-like properties in colon cancer, however, remain unclear. In this study, we found that ANQ inhibited growth of colon cancer cells. The 50% growth inhibitions (GI₅₀) of ANQ on HCT15 and LoVo were 34.8 ± 0.07 and 17.9 ± 0.07 ...

Abstract:
... Assessing habitat naturalness belongs to the most current issues in conservation biology. It has been recognized that plants are able to indicate the naturalness of their habitat. Thus, species may be given relative naturalness indicator values (i.e. scores on an ordinal scale), reflecting their different tolerances against habitat degradation. In the present study, our first goal was to test whet ...
