Since publication of our article [1], we have realised that the legend of Figure one needs to be corrected and should read as follows:

"Photomicrograph of Gc-5spg and Gc-6spg stained with an anti-activated caspase 3 antibody and counterstained with Haemaluin as described in Materials and Methods. A, Gc-5spg culture treated with 200 uM CAP for 24 h B, Gc-6spg culture treated with 250 uM CAP during 48 h."

We apologise for any confusion this may have caused.
