In this study, we quantified the ability of opioids present in biological samples to activate the μ-opioid receptor and TLR4 using cell-based assays. Each assay was standardised, in the presence of plasma, using morphine, its μ receptor-active metabolite morphine-6 glucuronide (M6G) and its μ receptor-inactive, but TLR4-active metabolite morphine-3(More)
BACKGROUND Tumor budding has been suggested to be a prognostic factor in various human cancers. However, the prognostic value of tumor budding for early-stage (cT1/2N0) tongue squamous cell carcinoma remains inconclusive. This study analyzed the correlation of tumor budding with the clinicopathologic features, and its prognostic significance for cT1/2N0(More)
AIM Chemotherapy-induced reactive oxygen species (ROS) not only contribute to apoptosis, but also trigger autophagy. Since autophagy is reported to protect cancer cells from apoptosis, this weakens the therapeutic effect of chemotherapy. This study aimed at identifying the key molecules that determine the cellular response to ROS and, therefore, provide(More)
Esa1 (essential Sas2-related acetyltransferase 1) and Tip60 (HIV-1 TAT-interactive protein, 60 kDa) are key members of the MYST family of histone acetyltransferases (HATs) and play important functions in many cellular processes. In this work, we designed, synthesized and evaluated a series of substrate-based analogs for the inhibition of Esa1 and Tip60. The(More)
Protein arginine methyltransferases (PRMTs) play important roles in both normal physiology and human diseases. Deregulation of PRMT activity has been linked to several pathological states such as cancer and cardiovascular disorders. Herein, we report our work of designing and using new fluorescent reporters to perform single-step analysis of substrate(More)
Collaborative Product Development (CPD) is an engineering process that involves decision-making through iterative communication and coordination among product designers throughout the lifecycle of the product. The high level of collaboration and communication of a CPD environment requires a robust Distributed Information System. In this paper, we review(More)
Histone acetyltransferases (HATs) are an important class of epigenetic enzymes involved in chromatin restructuring and transcriptional regulation. We describe in this paper a novel approach for the identification and characterization of HAT inhibitors using both fluorescence resonance energy transfer (FRET) and fluorescence polarization. Expressed protein(More)
Post-translational modifications (PTMs) are important strategies used by eukaryotic organisms to modulate their phenotypes. One of the well-studied PTMs, arginine methylation, is catalyzed by protein arginine methyltransferases (PRMTs) with SAM as the methyl donor. The functions of PRMTs have been broadly studied in different biological processes and(More)
