Article Abstract
Pancreatic ductal adenocarcinoma (PDA) has poor therapeutic options. Recent patient studies indicate that cholesterol-lowering statins have anti-tumor capacities. We examined several established and primary PDA and normal cell lines as well as PDA patient tissues (n = 68). We found that simvastatin inhibited viability, stemness, tumor growth and metastasis and that it enhanced the efficacy of gemcitabine. These changes were associated with modulation of Shh-related gene expression. Overexpression of Shh prevented the anti-cancer effect of simvastatin, and inhibition of Shh mimicked the simvastatin effect. In PDA tissues, expression levels of Shh, downstream mediators of Shh and progression markers, namely, cMet, CxCR4 and Vimentin, were lower when patients were prescribed statin medication prior to surgery. These results suggested that statins are cost effective and well-tolerated drugs for prevention and co-treatment of PDA.

Constructing a novel antibacterial platform is of great significance for inhibiting bacterial infections. In this work, we developed a composite hydrogel (CS/PPy/PDA hydrogel) by incorporating photothermal material polypyrrole (PPy), chitosan (CS) and polydopamine (PDA) into poly acrylamide (PAAM) hydrogel network. First, CS/PPy/PDA hydrogel could capture bacteria through strong electrostatic interactions, enhancing the contact between hydrogels and bacteria.

Glucose sensors are critical analytical devices designed for precise and continuous monitoring of glucose concentrations, playing a pivotal role in healthcare, particularly in diabetes management. Here, we synthesis glucose oxidase (GOx)/Se hydrogel to detect the glucose, thereby generating measurable electrical signals. Further, the transfection of electronic signals rely on the poly(dopamine) (PDA) grid in hydrogel.

Spinal cord injury (SCI) is exacerbated by the formation of an acidic microenvironment and extensive neuronal loss, both of which contribute to poor functional recovery. To address this, we developed lysine-polydopamine nanoparticles (Lys-PDA) as a multifunctional therapeutic platform for SCI. Lysine, a naturally occurring amino acid, possesses weak alkalinity and neuroprotective properties, but suffers from poor in vivo stability and non-specific distribution.

However, the mechanisms by which cancer cells concurrently co-opt these elements of hypoxic adaptation to promote metastasis remains poorly understood. Here, we report that hypoxia promotes metastasis by suppressing the JmjC-containing histone lysine demethylase Kdm8.

Background: Monosomy 45,X is commonly associated with congenital heart defects, particularly coarctation of the aorta (CoA). In this case, the patient developed respiratory distress due to hemodynamic instability from a large bidirectional patent ductus arteriosus (PDA) shunt and systemic hypoperfusion secondary to CoA, which complicated diagnosis and management.
Case Presentation: We report a 34-week premature female neonate weighing 1.
