CELL BIOLOGY. For the article “Integrin-mediated mechanotransduction requires its dynamic interaction with specific extracellular matrix (ECM) ligands” by Shila Jalali, Miguel A. del Pozo, Kuang-Den Chen, Hui Miao, Yi-Shuan Li, Martin A. Schwartz, John Y.-J. Shyy, and Shu Chien, which appeared in number 3, January 30, 2001, of Proc. Natl. Acad. Sci. USA (98, 1042–1046; First Published January 23, 2001; 10.1073/pnas.031562998), the authors note the following correction. The first sentence on page 1045, right column, fourth paragraph, lines 1–3, reads, “Recent study (23) has indicated that vascular endothelial growth factor receptor (VEGF-R) may be involved in integrin/Shc association.” This sentence should be changed to read, “Recent study (23) indicated that vascular endothelial growth factor receptor (VEGF-R) may interact with integrin for VEGF signaling.”
