Figure 7From: β1 integrin mediates an alternative survival pathway in breast cancer cells resistant to lapatinibβ1 is critical for the HCC1954 LTRes phenotype, but not parental or TRes. (A) Parental, LTRes, and TRes cells were plated on lrECM, subjected to AIIB2, and allowed to grow for 12 days. (B) Cells were subjected to two consecutive rounds of siRNA transfection as before, validated both before and during the experiment (top), and plated in lrECM (bottom).Back to article page
