Deficiency of the SMOC2 Matricellular Protein Impairs Bone Healing and Produces Age-Dependent Bone Loss

The authors report a patient with a loss-of-function of the secreted matricellular protein SPARC related modular calcium binding 2 (SMOC2) presenting severe oligodontia, microdontia, tooth root deficiencies, alveolar bone hypoplasia, and a range of skeletal malformations.

EpCAM Targeted 3WJ RNA Nanoparticle Harboring Delta-5-Desaturase siRNA Inhibited Lung Tumor Formation via DGLA Peroxidation

By incorporating epithelial cell adhesion molecule (EpCAM) aptamer and validated delta-5-desaturase (D5D) siRNA into the innovative three way-junction RNA-nanoparticle, target specific accumulation and D5D knockdown were achieved in the lung cancer cell and mouse models.

The Prostaglandin Synthases, COX-2 and L-PGDS, Mediate Prostate Hyperplasia Induced by Low-Dose Bisphenol A

In vitro studies showed that low-dose bisphenol A promoted the proliferation of human prostate fibroblasts and epithelial cells, and significantly upregulated the expression of cyclooxygenase-2 (COX-2) and L-PGDS in the cells.
