Upregulation of miR-21 (microRNA-21) and downregulation of miR-34b/c have been found in breast cancer (BC). However, their regulation mechanism and function roles in BC have not been fully addressed. Here, we report that miR-21 levels were inversely correlated with miR-34b/c levels in BC. MiR-21 upregulation contributes to PTEN downregulation, which is beneficial for the activation of PI3K/AKT ...
This work investigates the variability of ozone (O3), carbon monoxide (CO) and equivalent black carbon (BC) at the Italian Climate Observatory “O. Vittori” (ICOOV), part of the Mt. Cimone global GAW-WMO station (Italy). For this purpose, ICO-OV observations carried out in the period January 2007–June 2009, have been analyzed and correlated with the outputs of the FLEXPART Lagrangian dispersion ...
The objectives of this study were to assess the relative importance of either biotic or abiotic oxidation of biomassderived black carbon (BC) and to characterize the surface properties and charge characteristics of oxidized BC. We incubated BC and BC–soil mixtures at two temperatures (30 C and 70 C), with and without microbial inoculation, nutrient addition, or manure amendment for four months....
