Cell-Specific Functions of ADAM17 Regulate the Progression of Thoracic Aortic Aneurysm.
Conclusions: We have identified distinct cell-specific functions of ADAM17 in TAA progression, promoting pathological remodeling of SMC and impairing integrity of the intimal EC barrier. The dual impact of ADAM17 deficiency (or inhibition) in protecting two major cell types in the aortic wall highlights the unique position of this proteinase as a critical treatment target for TAA.

The anti-apoptotic ubiquitin conjugating enzyme BIRC6/BRUCE regulates autophagosome-lysosome fusion.
Abstract The Inhibitor of Apoptosis (IAP) family member, BIRC6/BRUCE is a ubiquitin conjugating E2 enzyme and a well-established anti-apoptosis regulator. However, its role in mammalian autophagy has not been shown. We identified BIRC6 as an important positive regulator of macroautophagy/autophagy by performing an siRNA screen targeting enzymes in the ubiquitin pathway. Compared to wild-type cells, BIRC6-deficient cells show accumulation of lipidated LC3B both at basal and starved conditions. Furthermore, BIRC6 deficiency blocks starvation-induced autophagic flux monitored by a tandem fluorescent autophagy sensor,...

Aminoacylase 3 Is a New Potential Marker and Therapeutic Target in Hepatocellular Carcinoma
Ras proteins (HRas, KRas and NRas) are common oncogenes that require membrane association for activation. Previous approaches to block/inhibit Ras membrane association were unsuccessful for cancer treatment in human clinical studies. In the present study we utilized a new approach to decrease Ras membrane association in hepatocellular carcinoma (HCC) cell lines via inhibition of an enzyme aminoacylase 3 (AA3; EC 3.5.1.114). AA3 expression was significantly elevated in the livers of HCC patients and HCC cell lines. Treatment of HepG2 cells with AA3 inhibitors, and HepG2 and HuH7 with AA3 siRNA significantly decreased Ras me...

A Study on Effect of Oxaliplatin in MicroRNA Expression in Human Colon Cancer
This study outlines the regulatory effects of oxaliplatin on miRNAs expression in colon cancer cells and correlates it with the changing microRNA expression with p53 and p73 expression status in cells. HCT116p53+/+ and HCT116p53-/- cells were exposed to oxaliplatin, and the cellular viability was determined by XTT. p73 was knocked down using siRNA and the tumor cells were then treated with oxaliplatin. The expression profile of 384 miRNAs was determined by TaqMan® human miRNA array and calculated by the ∆∆Ct method. Cellular viability was found to decrease after the treatment with oxaliplatin in a dose-dep...

Punching and Electroporation for Enhanced Transdermal Drug Delivery
Transdermal delivery has made an indispensable impact to medical practice, but often been limited by low efficiency due to the barrier of the outer stratum corneum layer of skin. In Issue 9 of Theranostics, Huang et al. [1] proposed a new design of transdermal gene delivery strategy via the combination of a microneedle roller and a flexible interdigitated electroporation array. With the assistance of the microneedle roller, a deep and uniform electric field in the skin can be formed, accompanying an enhanced transport efficiency even at a low voltage. Furthermore, this combination strategy can promote the gene expression a...

Flow-dependent epigenetic regulation of IGFBP5 expression by H3K27me3 contributes to endothelial anti-inflammatory effects
Conclusion: Taken together, our findings reveal that atheroprotective flow reduces H3K27me3 as a chromatin-based mechanism to augment the expression of genes that confer an anti-inflammatory response in the endothelium. Our study exemplifies flow-dependent epigenetic regulation of endothelial gene expression, and also suggests that targeting the EZH2/H3K27me3/IGFBP5 pathway may offer novel therapeutics for inflammatory disorders such as atherosclerosis.

Loss of the basic helix-loop-helix transcription factor Bhlhe41 induces cell death and impairs neurite outgrowth in Neuro2a cells.
Abstract The basic helix-loop-helix (bHLH) superfamily of transcription factors have been implicated in a wide range of cellular functions such as proliferation, differentiation, tumorigenesis, and circadian rhythms. In a previous siRNA-based screen, bHLH family member e41 (BHLHE41) had been identified as a putative regulator of neuronal differentiation; however, its function remains largely elusive. To this end, using the CRISPR-Cas9 system, we established an isogenic Neuro2a (N2a) cell line with biallelic targeting of Bhlhe41 gene (Bhlhe41-/-). In undifferentiated N2a cells, complete knockout of Bhlhe41 resulted...

Prox1 is essential for oligodendrocyte survival and regulates oligodendrocyte apoptosis via the regulation of NOXA.
Abstract Demyelinating diseases, such as multiple sclerosis, are known to result from acute or chronic injury to the myelin sheath and inadequate remyelination. Its underlying molecular mechanisms, however, remain unclear. The transcription factor prospero homeobox 1 (Prox1) plays an essential role during embryonic development of the central nervous system and cell differentiation. Thus, we aimed to investigate the role of Prox1 in the survival and differentiation of oligodendrocytes. Cell viability was measured by MTT assay. Flow cytometry was conducted to analyze cell apoptosis. Ectopic-Prox1 and shProx1 were us...

Synthesis of cationic branched tea polysaccharide derivatives for targeted delivery of siRNA to hepatocytes.
Abstract The cationic branched tea polysaccharide (CTPSA) derivative bearing N-acylurea and 3-(dimethylamino)-1-propylamine residues was synthesized and characterized using FTIR and 1H NMR spectroscopy. A nonspecific siRNA (NsiRNA) was used as a model molecule of functional siRNA that could downregulate the over-expressed glycometabolism enzymes in liver. The result of agarose gel electrophoresis confirmed that the CTPSA and NsiRNA could form the stable complexes when their weight ratio was larger than 18. The zeta potentials and sizes the complexes were in the range of +8-+15 mv and 120-150 nm, respectively. ...

Intracellular miRNA or siRNA delivery and function.
Abstract Nanocarrier-mediated delivery and release of short non-coding RNA (e.g., miRNA or siRNA) into the cells with subsequent suppression of the populations of some of the mRNAs and proteins is of interest in the context of the development of a new generation of drugs. Bearing in mind such applications, the author shows the specifics of the corresponding transient kinetics by using three generic models without and with feedback resulting in bistability in the gene expression. In the absence of feedback, the suppression of the mRNA and protein population is transient. In the case of bistable kinetics, non-coding...

Galactose Derivative-Modified Nanoparticles for Efficient siRNA Delivery to Hepatocellular Carcinoma.
In this study, we assembled lipid/calcium/phosphate nanoparticles (LCP NPs) conjugated with eight types of galactoside derivatives and demonstrated that phenyl β-d-galactoside-decorated LCP NPs (L4-LCP NPs) exhibited a superior siRNA delivery into HCC cells compared to normal hepatocytes. VEGF siRNAs delivered by L4-LCP NPs downregulated VEGF expression in HCC in vitro and in vivo and led to a potent antiangiogenic effect in the tumor microenvironment of a murine orthotopic HCC model. The efficient delivery of VEGF siRNA by L4-LCP NPs that resulted in significant tumor regression indicates that phenyl galactoside could be...
