Correction: Glycogen Synthase Kinase-3 regulates IGFBP-1 gene transcription through the Thymine-rich Insulin Response Element

Following publication of the original article [1], the authors reported errors in two panels of Fig. 3 where a) the 15 min data for phosphoT389S6K1 was duplicated in both the 15 min and 3 h lanes and b) the 3 h data for total MAPK was duplicated in both the 15 min and 3 h lanes. The authors confirmed these are two genuine errors by locating the original ECL film for the western blots in question from experiments done on 5th April 2002. We attach the original Fig. 3 with errors circled along with a scan of the entire film containing the primary 15 min and 3 h data of the MAPK and phosphoT389S6K1 data. We also provide the corrected figure with the missing data from the two panels inserted where indicated by *.
