The originally published article referred to retinoblastoma or RB ‘hyperphosphorylation’ three times in the legend for Figure 2 and once in the main text (in the section headed ‘Cellular senescence mechanisms’), which was incorrect. The text should have read retinoblastoma or RB ‘hypophosphorylation’. This has been corrected in the HTML and PDF versions of the manuscript.
