Vascular PPARβ/δ Promotes Tumor Angiogenesis and Progression.

Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors, which function as transcription factors. Among them, PPARβ/δ is highly expressed in endothelial cells. Pharmacological activation with PPARβ/δ agonists had been shown to increase their angiogenic properties.

Altered VEGF Splicing Isoform Balance in Tumor Endothelium Involves Activation of Splicing Factors Srpk1 and Srsf1 by the Wilms' Tumor Suppressor Wt1.

Angiogenesis is one hallmark of cancer. Vascular endothelial growth factor (VEGF) is a known inducer of angiogenesis. Many patients benefit from antiangiogenic therapies, which however have limitations.

Pseudo-tumor of the scrotum, a rare clinical presentation of dirofilariasis: a report of two autochtonous cases due to Dirofilaria repens.

In Europe, human dirofilariasis refers to a group of autochtonous parasitic infections caused by tissue nematodes of the genus Dirofilaria, responsible for two distinct clinical presentations: Dirofilaria immitis usually presenting as pulmonary lesions and Dirofilaria repens as subcutaneous nodules. Rare in humans, genital involvement manifests itself as pseudotumor nodules affecting the scrotum, epididymis, or spermatic cord. We report on two cases of Dirofilaria repens infections, involving the spermatic cord and epididymis.

Evolution of nevi during treatment with natalizumab: A prospective follow-up of patients treated with natalizumab for multiple sclerosis.

Background: Natalizumab is a monoclonal antibody directed against α₄ integrin used in the treatment of multiple sclerosis (MS). Four cases of melanomas occurring in patients prescribed natalizumab to treat MS were recently reported. Although some fundamental data suggested that α₄β1 integrin could be linked to the invasiveness of melanoma, none showed any relation with the transformation of melanocytes.
