A bispecific decoy receptor VEGFR-EGFR/Fc binding EGF-like ligands and VEGF shows potent antitumor efficacy.

Epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor (VEGFR) represent two clinically validated targets for a variety of human cancers, and dual inhibition of EGFR and VEGF(R) has demonstrated superior activity to single EGFR inhibitors. This study was to construct a novel bispecific decoy receptor VEGFR-EGFR/Fc that contains Fc portion of human IgG1 acted as molecular scaffold, and the immunoglobulin-like domain 1-3 of VEGFR1 and extracellular domain of EGFR fused to the N-terminal and C-terminal of Fc, respectively, aiming at capturing the EGF-like ligands and VEGF. ELISA showed that VEGFR-EGFR/Fc bound to EGF, TGF-α and VEGF with high affinity.

Biparametric prostate MRI and clinical indicators predict clinically significant prostate cancer in men with "gray zone" PSA levels.

Purpose: To predict clinically significant prostate cancer (cs-PCa) by combining the Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) score based on biparametric magnetic resonance imaging (bp-MRI) and clinical indicators in men with prostate-specific antigen (PSA) levels in the gray zone of 4-10 ng/mL.

Method: We retrospectively analyzed 364 patients with elevated PSA levels in the gray zone who had pathologically confirmed disease and had undergone MRI examinations from January 2015 to October 2019; a training group (n = 255) and validation group (n = 109) were randomly established. Multivariate logistic regression analysis of the training group was performed to identify the independent predictors for cs-PCa, thereby establishing a predictive model that was evaluated in the training and validation groups by analyzing the receiver operating characteristic (ROC) curve.

Phosphate stimulates myotube atrophy through autophagy activation: evidence of hyperphosphatemia contributing to skeletal muscle wasting in chronic kidney disease.

Background: Accelerated muscle atrophy is associated with a three-fold increase in mortality in chronic kidney disease (CKD) patients. It is suggested that hyperphosphatemia might contribute to muscle wasting, but the underlying mechanisms remain unclear. Although evidence indicates that autophagy is involved in the maintenance of muscle homeostasis, it is not known if high phosphate levels can result in activation of autophagy, leading to muscle protein loss.
