ADIPOR2 and breast carcinoma: On the other hand, the increase in the expression of AdipoR2 mRNA and the decrease in the cell population at all concentrations at 96 h of stimulation could indicate that the effective receptor for the in vivo signaling of adiponectin in the breast cancer tissue is AdipoR2; this corresponds to that found in 2009 by Jardé et al. [27].
