The devil is in the details

In mouse models, NRP2a inhibited tumor cell proliferation while NRP2b promoted metastasis and progression. Cancer stem cells were also reduced in NRP2b knockdown models, providing new insights into lung cancer progression. The study suggests that targeting NRP2b may lead to improved therapies for non-small cell lung cancer.
