Leukotriene B 4 antagonism ameliorates experimental lymphedema
Abstract
Acquired lymphedema is a cancer sequela and a global health problem currently lacking pharmacologic therapy. We have previously demonstrated that ketoprofen, an anti-inflammatory agent with dual 5-lipoxygenase and cyclooxygenase inhibitory properties, effectively reverses histopathology in experimental lymphedema. We show that the therapeutic benefit of ketoprofen is specifically attributable to its inhibition of the 5-lipoxygenase metabolite leukotriene B 4 (LTB 4 ). LTB 4 antagonism reversed edema, improved lymphatic function, and restored lymphatic architecture in the murine tail model of lymphedema. In vitro, LTB 4 was functionally bimodal: Lower LTB 4 concentrations promoted human lymphatic endothelial cell sprouting and growth, but higher concentrations inhibited lymphangiogenesis and induced apoptosis. During lymphedema progression, lymphatic fluid LTB 4 concentrations rose from initial prolymphangiogenic concentrations into an antilymphangiogenic range. LTB 4 biosynthesis was similarly elevated in lymphedema patients. Low concentrations of LTB 4 stimulated, whereas high concentrations of LTB 4 inhibited, vascular endothelial growth factor receptor 3 and Notch pathways in cultured human lymphatic endothelial cells. Lymphatic-specific Notch1 -/- mice were refractory to the beneficial effects of LTB 4 antagonism, suggesting that LTB 4 suppression of Notch signaling is an important mechanism in disease maintenance. In summary, we found that LTB 4 was harmful to lymphatic…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
