RETRACTION: Spider Eye Development Editing and Silk Fiber Engineering Using CRISPR‐Cas

Abstract

RETRACTION: E. Santiago‐Rivera and T. Scheibel, “Spider Eye Development Editing and Silk Fiber Engineering Using CRISPR‐Cas,” Angewandte Chemie International Edition 64, no. 25 (2025): e202502068, https://doi.org/10.1002/anie.202502068.The above article, published online on 13 April 2025 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor‐in‐Chief, Frank Maass; the German Chemical Society; and Wiley‐VCH GmbH. In ongoing studies using CRISPR‐Cas in spiders, the authors performed additional tests on the knock‐out (KO) as well as knock‐in (KI) mutants in correspondence with geneticists specializing in the use of CRISPR‐Cas. The authors were unable to confirm that the KO as well as the KI occurred at the intended place in the genome. As the results in this study cannot be verified, the article must therefore be retracted.
