A Krüppel-Associated Box-Zinc Finger Protein, NT2, Represses Cell-Type-Specific Promoter Activity of the α2(XI) Collagen Gene

Volume 20, no. 12, p. 4428-4435, 2000, and volume 22, no. 12, p. 4256-4267, 2002. These two articles were subject to previous partial retractions (volume 26, no. 13, p. 5202, 2006, and volume 26, no. 21, p. 8215-8216, 2006, respectively). Since our original partial retractions, questions have arisen concerning the validity of other figures in these articles that were provided by one of the authors (K.T.). We therefore retract fully these two articles as well as the previous partial retractions.
