Brain-Targeting Emodin Mitigates Ischemic Stroke via Inhibiting AQP4-Mediated Swelling and Neuroinflammation.

Failure to achieve target-specific delivery to ischemic brain sites has hampered the clinical efficacy of newly developed therapies for ischemic stroke. Emodin, an active ingredient isolated from traditional Chinese medicine, has been indicated to alleviate ischemic stroke; however, the underlying mechanism remains unclear. In this study, we aimed to achieve brain-targeted delivery of emodin to maximize its therapeutic efficacy and elucidate the mechanisms by which emodin alleviates ischemic stroke.

YY1-induced upregulation of LncRNA-ARAP1-AS2 and ARAP1 promotes diabetic kidney fibrosis aberrant glycolysis associated with EGFR/PKM2/HIF-1α pathway.

Dimeric pyruvate kinase (PK) M2 (PKM2) plays an important role in promoting the accumulation of hypoxia-inducible factor (HIF)-1α, mediating aberrant glycolysis and inducing fibrosis in diabetic kidney disease (DKD). The aim of this work was to dissect a novel regulatory mechanism of Yin and Yang 1 (YY1) on lncRNA-ARAP1-AS2/ARAP1 to regulate EGFR/PKM2/HIF-1α pathway and glycolysis in DKD. We used adeno-associated virus (AAV)-ARAP1 shRNA to knocked down ARAP1 in diabetic mice and overexpressed or knocked down YY1, ARAP1-AS2 and ARAP1 expression in human glomerular mesangial cells.

Directing osteogenic differentiation of BMSCs by cell-secreted decellularized extracellular matrixes from different cell types.

Cell-secreted decellularized extracellular matrixes (D-ECM) are promising for conferring bioactivity and directing cell fate to facilitate tissue regeneration. A cell sheet is a good shape for obtaining D-ECM after decellularization. In this study, cell sheets derived from bone marrow mesenchymal stem cells (BMSCs), MC3T3 osteoblasts, and L929 fibroblasts were decellularized, the three types of D-ECMs obtained were investigated for their capabilities in inducing osteogenic differentiation of re-seeded BMSCs.

Photoluminescent polyphosphazene nanoparticles for in situ simvastatin delivery for improving the osteocompatibility of BMSCs.

Nanomedicines have found promising applications in regulating the biological behaviors of cells because of the cell endocytosis effect. To enhance the osteogenic differentiation of bone marrow mesenchymal stromal cells (BMSCs), which is one of the key issues in relation to bone regeneration, a biodegradable simvastatin-bearing polyphosphazene prodrug was synthesized and made into nanoparticles (NPs). At the same time, photoluminescent tryptophan ethyl ester and hydrolyzable glycine ethyl ester were introduced as co-substituted side groups onto the polyphosphazene backbone.

The complete mitochondrial genome of Heliconius pachinus (Insecta: Lepidoptera: Nymphalidae).

The complete mitochondrial genome of Heliconius pachinus has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 15,369 bp in length, and comprises the typical components: 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs) and 1 D-loop region. PCGs are mostly initiated with either the ATN codons (COII, COIII, Cytb, ND2, ND3, ND4, ND4L, ND5, ND6, ATP6 & ATP8) or the TTG codon (ND1); the COI gene may use the unusual CGA as its initiation codon, as suggested for other lepidopteran species.

Identification of novel scaffold of benzothiazepinones as non-ATP competitive glycogen synthase kinase-3β inhibitors through virtual screening.

Glycogen synthase kinase-3β (GSK-3β) is an important serine/threonine kinase that has been proved as a key target for neurodegenerative diseases and diabetes. Up to date, most of known inhibitors are bound to the ATP-binding pocket of GSK-3β, which might lead widespread effects due to the high homology between kinases. Recently, some of its non-ATP competitive inhibitors had been confirmed having therapeutical effects owing to their high selectivity.

Design, synthesis and biological evaluation of benzothiazepinones (BTZs) as novel non-ATP competitive inhibitors of glycogen synthase kinase-3β (GSK-3β).

Glycogen synthase kinase-3β (GSK-3β) plays a key role in type II diabetes and Alzheimer's diseases, to which non-ATP competitive inhibitors represent an effectively therapeutical approach due to their good specificity. Herein, a series of small molecules benzothiazepinones (BTZs) as novel non-ATP competitive inhibitors of GSK-3β have been designed and synthesized. The in vitro evaluation performed by luminescent assay showed most BTZ derivatives have inhibitory effects in micromolar scale.
