Background: The growing spread of drug resistance in Helicobacter pylori has caused concern. Urease is one the most important enzymes associated with H. activity. Oxadiazoles have a wide range inhibitory activities. aim this study was to investigate new oxadiazole compounds as urease inhibitors pylori. Methods: synthesized were reused ligands previous study, and initial structure optimized by M...

MiR-134 can function as an oncogene or a tumor suppressor gene depending on cell type. However, the function of miR-134 in gastric cancer remains unclear to date. This study aims to evaluate the function of miR-134 in gastric cancer and investigate its effect on the sensitivity of gastric cancer cells to 5-FU. The expression of miR-134 assayed by real-time PCR was significantly lower in gastric...

Following our previous studies on potassium poly(heptazine imide) (K-PHI), that is, catalyzed photooxidative [3+2] aldoxime-to-nitrile addition to form 1,2,4-oxadiazoles, we discovered electron-rich oximes yield the parent aldehydes instead of target products. In this work, mechanism singlet oxygen-mediated deoximation process was established using a series control reactions and spectroscopic m...

Hsa-miRNA-134 (miR-134) has recently been discovered to have anticancer efficacy in different organs. However, the role of miR-134 on non-small cell lung cancer (NSCLC) is still ambiguous. In this study, we investigated the role of miR-134 on the development of NSCLC. The results indicated that miR-134 was significantly down-regulated in primary tumor tissues and very low levels were found in N...

MicroRNAs (miRNAs) are post-transcriptional modulators of gene expression and play an important role in reprogramming process; however, relatively little is known about the underlying regulatory mechanism of miRNAs on how they epigenetically modulate reprogramming and pluripotency. Here, we report that the expression level of microRNA-134 (miR-134) was low in mouse embryonic stem cells (mESCs) ...
