Unraveling the Action Mechanism of Tubeimoside-1 against Tumor Microvessels via Network Pharmacology and Experimental Validation.

Tubeimoside-1 (TBMS1) is a plant-derived triterpenoid saponin that exhibits pharmacological properties and anti-tumor effects, but the anti-tumor microvessels of action of TBMS1 remains to be completely elucidated. This study aims to verify the effect of TBMS1 on tumor microvessels and its underlying mechanism. A SKOV3 xenografted mouse model were constructed to evaluate the anti-tumor microvessels of TBMS1 in , followed by function assays to verify the effects of TBMS1 on the proliferation, cell cycle, migration, and tubule formation of vascular endothelial cells in .

Comparative proteomics analysis of cerebrospinal fluid of patients with Guillain-Barré syndrome.

To better understand the pathophysiologic mechanisms underlying Guillain-Barré syndrome (GBS), Comparative proteomic analysis of cerebrospinal fluid (CSF) between patients with GBS (the experiment group) and control subjects suffering from other neurological disorders (the control group) was carried out using two-dimensional gel electrophoresis (2-DE) technique, in combination with matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) and database searching to determine abnormal CSF proteins in GBS patients. Image analysis of 2-DE gels silver stained revealed that 10 protein spots showed significant differential expression between the two groups of CSF samples. The expression of cystatin C, transthyretin, apolipoprotein E and heat shock protein 70 were decreased.
