In a previous study (7) we observed that long‐term (several months) knockdown of galectin‐1 in U87 glioma cells increased expression of alpha 9 integrin, whereas in the present study we did not observe effects on integrin expression levels (including alpha 9) following short‐term (several days) knockdown of galectin‐1. Here, ITGA9 is linked to glioma.
