BACKGROUND To identify the effects of microRNA (miR)-219-5p on morphine-induced apoptosis by targeting WEE1. MATERIAL AND METHODS Forty Balb/C mice (Toll-like receptor 9, TLR9 knockout) were randomly allocated to the experimental and control groups (20 in each group). The baseline miR-219-5p expression was detected using quantitative real-time PCR (qRT-PCR). After morphine was injected at 6 h o...
Chordoma is a rare malignant bone tumor that is usually localized to the skull base, vertebral column and sacrum. The transcription factor brachyury, which is encoded by the T gene, has a critical role in the development and progression of chordoma, although the mechanisms underlying brachyury regulation remain unclear. The aim of the current study was to identify and characterize microRNAs (mi...
BACKGROUND/AIMS Keratinocyte growth factor (KGF) plays a critical role in prevention of cirrhosis and enhancement of liver regeneration. However, the molecular regulation of KGF in liver is unknown. MicroRNAs (miRNAs) control the pathogenesis of cirrhosis, whereas the exact involved miRNAs and molecular signaling pathways remain ill-defined. Here we addressed these questions. METHODS We exami...
any professors want to promote students’ critical thinking, foster self-examination, and facilitate civic engagement; however, these professors may be uncertain about how they can accomplish these objectives. The paradigm of transformative pedagogy (Mezirow and Associates 2000; Taylor 2000) can provide faculty with a useful theoretical perspective to guide their efforts. Descriptions of transfo...

Fenofibrate is more effective drug as compared to other fibrates. But low bioavailability of it is due to its poor aqueous solubility. The purpose of present study was to improve fenofibrate dissolution through its formulation into liquisolid tablets and then to investigate in vitro performance of prepared liquisolid systems. By use of this technique, liquid medications such as solutions or sus...
Tau is a highly abundant and multifunctional brain protein that accumulates in neurofibrillary tangles (NFTs), most commonly in Alzheimer's disease (AD) and primary age-related tauopathy. Recently, microRNAs (miRNAs) have been linked to neurodegeneration; however, it is not clear whether miRNA dysregulation contributes to tau neurotoxicity. Here, we determined that the highly conserved brain mi...
BACKGROUND Esophageal cancer (EC), an aggressive digestive tract malignancy, is one of the leading causes of cancer-related deaths worldwide. Besides environmental risk factors, genetic factors might play a key role in the EC carcinogenesis. The aim of the study is to evaluate the association of miR219-1 single-nucleotide polymorphisms (SNPs) with EC. METHODS A total of 248 Kazakh esophageal ...
We have designed MI-219 as a potent, highly selective and orally active small-molecule inhibitor of the MDM2-p53 interaction. MI-219 binds to human MDM2 with a K(i) value of 5 nM and is 10,000-fold selective for MDM2 over MDMX. It disrupts the MDM2-p53 interaction and activates the p53 pathway in cells with wild-type p53, which leads to induction of cell cycle arrest in all cells and selective ...
