Gallbladder cancer (GBC) is the most common malignant tumor of the biliary track system. Epithelial-mesenchymal transition (EMT) plays a vital role in the process of tumor metastasis. Mesenchymal-like cells can serve as a source of cancer stem cells (CSCs), which can confer the EMT phenotype. Placental growth factor (PLGF) belongs to the VEGF family and plays a vital role in cancer. However, the underlying molecular mechanisms about the influence of PLGF on EMT in GBC remain unknown. Here we show that PLGF expression levels were higher in GBC tissues than in normal adjacent tissues (NATs) and were associated with poor prognosis in GBC patients...

Preeclampsia is a complication of pregnancy manifested as maternal hypertension (HTN-Preg) and fetal growth restriction (IUGR), with unclear mechanism. Placental ischemia increases antiangiogenic soluble fms-like tyrosine-kinase-1 (sFlt-1) relative to angiogenic placental-growth-factor (PlGF); however, the molecular targets are unclear. To test the hypothesis that placental ischemia-induced changes in sFlt-1 and PlGF target vascular and uteroplacental matrix metalloproteinases (MMPs), we tested if raising sFlt-1/PlGF ratio by infusing sFlt-1 (10 µg/kg/day) in pregnant (Preg) rats increases blood pressure (BP) and alters MMPs, and if correcting sFlt-1/PlGF by infusing PlGF (20 µg/kg/day) in Preg rats with reduced uterine perfusion pressure (RUPP) improves BP and reverses the changes in MMPs...

BACKGROUND: Preeclampsia (PE) is considered a specific vascular disease in which endothelial dysfunction may be the crucial factor of its pathogenesis. It has been suggested that strontium (Sr) may play a role in the pathophysiology of PE. Our group established in a previous study the serum levels of Sr in healthy pregnancies, and the main aim of the present study was to evaluate Sr concentrations and oxidative status in preeclamptic women. METHODS: The study population included women with early-onset PE (E-PE, n = 39), late-onset PE (L-PE, n = 67) and serial samples from a subset of preeclamptic women (PE-ss, n = 20)...

BACKGROUND: Bone marrow stromal cells (BMSCs) have classically been cultured in media supplemented with fetal bovine serum (FBS). As an alternative to FBS, pooled solvent detergent apheresis platelets, HPGF-C18, was evaluated for BMSC culture. METHODS: A comparison of passage 2 BMSC growth revealed that 10% HPGF-C18 produced similar cell numbers as 20% FBS. Marrow aspirates from 5 healthy subjects were cultured for 4 passages in 10% HPGF-C18 or 20% FBS and were analyzed for proliferation, colony formation efficiency (CFE), surface marker expression, suppression of mixed lymphocyte reactions (MLRs), global gene and microRNA expression analysis...
