Acute vascular and cardiac effects of lenvatinib in mice.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTyrosine kinase inhibitors (TKIs) targeting vascular endothelial growth factor (VEGF) receptor signalling are used in cancer therapy to inhibit angiogenesis. Unfortunately, VEGF inhibitors are known to induce severe hypertension in patients. This study aimed to elucidate the impact of the TKI lenvatinib on blood pressure, arterial stiffness, vascular reactivity, as well as cardiac function in a short-term murine model to shed light on potential contributors to cardiovascular (CV) toxicities associated with VEGF inhibition.
methodsMale C57BL/6J mice were randomly divided into 2 cohorts, either treated for 4 days with lenvatinib 4 mg/kg/day or 40% hydroxypropyl β-cyclodextrin as control. In an additional study, mice were subjected to a 4-day treatment followed by a 4-day wash-out, with echocardiography and blood pressure measurements performed on day 2 and 7. Subsequently, ex vivo vascular reactivity of thoracic aortic segments was determined.
resultsLenvatinib induced hypertension and arterial stiffness (i.e., increased pulse wave velocity), starting from day 2 of treatment. Further, left ventricular ejection fraction was reduced and the ventricle dilated upon treatment. Lenvatinib induced neither endothelial dysfunction nor impaired vascular smooth muscle cell reactivity to nitric oxide (NO). Interestingly, lenvatinib demonstrated a concentration-dependent increase in ATP-mediated relaxation. In addition, after the 4-day wash-out period, lenvatinib-treated mice did not show complete remission of hypertension. However, arterial stiffness, ATP-mediated relaxation and cardiac adaptation were recovered.
conclusionThis comprehensive investigation provides valuable insights into the interplay between VEGF inhibition, vascular function and cardiac outcomes, emphasising the need for nuanced understanding and further exploration of the differential effects of lenvatinib on the CV system. Additionally, the study proposes a synergistic formation between VEGF and ATP, indicating an enhanced response via P2Yx receptor signalling.
