micrornas are highly conserved small non-coding regulatory rnas that involve in post transcriptional regulating of gene expression during different cellular mechanisms. aberration of mir-218 expression during tumorigenesis of different solid tumors has been reported by numerous studies. in current systematic review article, by using the terms “mir-218” and “cancer” we first searched for english...

MicroRNAs (miRs) act as oncogenes or tumor-suppressor genes, and regulate the proliferation, apoptosis, invasion, differentiation, angiogenesis and behavior of glioma stem cells, which are important in glioma development and recurrence. The present study was performed to investigate the impact of miR-218-5p on stem cell properties and invasive ability of the A2B5+CD133- human glioma stem cell s...

The selective oxidation of styrene with highly efficient, environmentally benign, and cost-effective catalysts are great importance for sustainable chemical processes. Here, we develop an in situ self-assembly strategy to decorate Cu-based metal-organic framework (MOF) Cu-BDC-NH2 nanocrystals on Cu2O octahedra construct a series Cu2O@Cu-BDC-NH2 styrene. Using H2O2 as green oxidants, the optimiz...

Organic dyes can enter water bodies through industrial wastes and may pose a threat to the health of aquatic organisms human. Metal organic framework derived carbon materials (CMOFs) have shown excellent performance for aqueous dye adsorption. However, few studied multimetallic CMOFs removal. Herein, ternary metal oxide embedded from amino-modified (CMOF(Fe/Al/Ni 8/7/5)-NH2) has been developed ...

The intrinsic conformational preferences of small peptides may provide additional insight into the thermodynamics and kinetics protein folding. In this study, we explore underlying energy landscapes two model peptides, namely, Ac-Ala-NH2 Ac-Ser-NH2, using geometry-optimization-based tools developed within context landscape theory. We analyze not only how side-chain polarity influences structura...

MicroRNAs (miRNAs) are small non-coding RNAs that are key post-transcriptional regulators of gene expression. MicroRNA-214 (miR-214) and microRNA-218 (miR-218) have shown the function of tumor suppressors in various types of human cancers. However, the biological functions of miR-214 and miR-218 in breast cancer have not been elucidated completely. The present study evaluated the expression and...

Wnt signaling is implicated in bone formation and activated in breast cancer cells promoting primary and metastatic tumor growth. A compelling question is whether osteogenic miRNAs that increase Wnt activity for bone formation are aberrantly expressed in breast tumor cells to support metastatic bone disease. Here we report that miR-218-5p is highly expressed in bone metastases from breast cance...

Using naturally serum-free SU-ECM basement membranes as invasion substrates showed that plasma fibronectin was necessary to stimulate invasion by DU 145 human and metastatic MATLyLu (MLL) rat prostate carcinoma cells. This activity mapped to the PHSRN sequence, which induced invasion through alpha5beta1 integrin. PHSCN, a competitive inhibitor, blocked both PHSRN- and serum-induced invasion. Ac...

The antimicrobial peptide KLKLLLLLKLK-NH2 was developed based on sapesin B, and synthesized using D-amino acids. Biochemical properties of the D-form and L-form KLKLLLLLKLK-NH2 peptides were compared. In order to limit the effects due to bacterial resistance to proteolysis, antimicrobial activities of the peptides were evaluated after short-term exposure to bacteria. D-form KLKLLLLLKLK-NH2 exhi...
