Epithelial-mesenchymal transition (EMT) is closely implicated in the pathogenesis of idiopathic pulmonary fibrosis. Associated with this phenotypic transition is the acquisition of an elongated cell morphology and establishment of stress fibers. The extent to which these EMT-associated changes influence cellular mechanics is unclear. We assessed the biomechanical properties of alveolar epithelial cells (A549) following exposure to TGF-beta 1. Using atomic force microscopy, changes in cell stiffness and surface membrane features were determined. Stimulation with TGF-beta 1 gave rise to a significant increase in stiffness, which was augmented by a collagen I matrix. Additionally, TGF-beta 1-treated cells exhibited a rougher surface profile with notable protrusions. Simultaneous quantitative examination of the morphological attributes of stimulated cells using an image-based high-content analysis system revealed dramatic alterations in cell shape, F-actin content and distribution. Together, these investigations point to a strong correlation between the cytoskeletal-associated cellular architecture and the mechanical dynamics of alveolar epithelial cells undergoing EMT.

Summary: This review discusses the potential of nuclear medicine imaging techniques in inhalation biopharmaceutical research, including the evaluation of pulmonary drug deposition, assessment of intrapulmonary pharmacokinetics, and quantification of the pharmacodynamic effect of inhaled drugs. Despite the limited use of imaging techniques in pulmonary drug development, they have the potential to bridge the knowledge gap between animal models and humans with respect to the pulmonary disposition of inhaled drugs.

Knockout of ABCC1 in NCI-H441 cells reveals CF to be a suboptimal substrate to study MRP1 activity in organotypic in vitro models

Summary: Multidrug resistance-associated protein 1 (MRP1/ABCC1) is an efflux transporter responsible for the extrusion of endogenous substances as well as xenobiotics and their respective metabolites. The generation of an ABCC1-/- clone based on the human distal lung epithelial cell line NCI-H441 via a targeted CRISPR/Cas9 approach provides a useful tool to study MRP1 function in vitro. The ABCC1-/- NCI-H441 clone showed complete absence of mRNA and protein, and retained the ability to form electrically tight barriers.

Summary: This study explored the use of nanocarriers to deliver dexamethasone for treating rheumatoid arthritis. The results showed that this method increased the accumulation of dexamethasone in the arthritic area, had a dose-dependent healing effect, and reduced the accumulation of the RA mediator RANKL. This study provides a feasible strategy for improving rheumatoid arthritis therapy.

Summary: In this study, iron-doped hydroxyapatite (FeHA) was evaluated as a potential nanomedicine approach for treating PDAC. The results showed that FeHA, in combination with a sublethal dose of the GPX4 inhibitor RSL3, could trigger ferroptosis in KRAS mutant PANC-1 cells while sparing normal human cells. The induction of ferroptosis by FeHA plus RSL3 was found to be dependent on the metalloreductase STEAP3 in PDAC cells.

Summary: The emergence of antibiotic-resistant bacteria in severe infections is a growing concern, particularly in hospital environments. Metal-based nanomaterials have shown potential as an alternative to combat these bacteria, but there is a risk of bacterial resistance and environmental accumulation.
