Embryonic microenvironment suppresses YY1 and YY1-related genes in prostate cancer stem cells.

Yin yang 1 (YY1), a transcription factor, plays crucial roles in cell fate specification, differentiation, and pluripotency during embryonic development. It is also involved in tumorigenesis, drug resistance, metastasis, and relapse caused by cancer stem cells (CSCs), particularly in prostate cancer (PCa). Targeting YY1 could potentially eliminate prostate CSCs (PCSCs) and provide novel therapeutic approaches.

Co-Delivery of siRNA and Docetaxel to Cancer Cells by NLC for Therapy.

The present study aims to develop a delivery system that can carry small interference RNA (siRNA) with small-molecule chemotherapeutic drugs, which can be used in cancer treatment. The drug delivery system combines the advantages of a therapeutic agent with two different mechanisms to ensure that it is used efficiently for cancer therapy. In this study, a nanostructured lipid carrier system was prepared, Docetaxel was loaded to these systems, and the Eph siRNA was adsorbed to the outer surface.

Ketorolac Tromethamine Loaded Nano-Spray Dried Nanoparticles: Preparation, Characterization, Cell Viability, COL1A1 Gene Simulation and Determination of Anti-inflammatory Activity by HET-CAM Assay.

Background: Ketorolac tromethamine (KT) is a non-steroidal anti-inflammatory drug from the heteroaryl acetic acid derivatives family. The most widely used new nanotechnological approaches for topical drug delivery are polymeric nanoparticles (NPs).

Objective: Successful results have been obtained with low doses in many treatments, such as cancer, antimicrobial, pain, made with nanoparticle formulations of drug active ingredients.

The Effect of Ex-Vivo Hyaluronic Acid on Myofibroblast and Collagen in Dupuytren Disease.

Dupuytren disease (DD) is characterised by increased myofibroblast/fibroblast activity and type3/type1 collagen ratios. Hyaluronic acid (HA) is major component of the extracellular matrix and some studies have showed that HA limits myofibroblast activity and decreases type3/type1 collagen ratio. The aim of this study is to determine the effect of the ex-vivo application of HA on cultured fibroblasts obtained from normal and diseased tissue from patients with DD.

Discovery of the 4-aminopiperidine-based compound EM127 for the site-specific covalent inhibition of SMYD3.

Recent findings support the hypothesis that inhibition of SMYD3 methyltransferase may be a therapeutic avenue for some of the deadliest cancer types. Herein, active site-selective covalent SMYD3 inhibitors were designed by introducing an appropriate reactive cysteine trap into reversible first-generation SMYD3 inhibitors. The 4-aminopiperidine derivative EM127 (11C) bearing a 2-chloroethanoyl group as reactive warhead showed selectivity for Cys186, located in the substrate/histone binding pocket.
