Arachidonate lipoxygenases (ALOX) have been implicated in playing a critical role in tumorigenesis, development, and metastasis.
We previously reported that ALOX12 is involved in breast cancer chemoresistance.
In this study, we demonstrate that the ALOX5 activation correlates with the HER2 expression and mediates breast cancer growth and migration.
We found that the ALOX5 expression and activity were upregulated in breast cancer patients, particularly in those tissues with HER2-positive.
ALOX5 upregulation was also observed in HER2-positive breast cancer cells.
In contrast, HER2 inhibition led to decreased expression and activity of ALOX5 but not ALOX5AP, suggesting that HER2 specifically regulates the ALOX5 expression and activity in breast cancer cells.
We further demonstrated that ALOX5 is important for breast cancer biological activities with the predominant roles in growth and migration, likely through RhoA, focal adhesion, and PI3K/Akt/mTOR signaling but not epithelial mesenchymal transition (EMT).
Our work is the first to report a correlation between the ALOX5 activity and HER2 overexpression in breast cancer.
Our findings also highlight the therapeutic value of inhibiting ALOX5 in breast cancer, particularly those patients with the HER2 overexpression.
