Summary: The extracellular matrix (ECM) of the lung, composed mainly of collagens, elastin, and proteoglycans, provides support to lung cells. Aberrant increased deposition of ECM in lung fibrosis changes filament organization and stiffens the ECM, leading to the profibrotic profile of pulmonary cells. The study examines changes in ECM properties during fibrosis development and identifies potential pharmacological targets to hinder its progression.

Summary: Scanning probe microscopy (SPM) is a powerful technique that allows for the observation and analysis of nanoscale materials and biological molecules through the use of sharp probes that scan the sample surface. This method, which includes scanning tunneling microscopy (STM) and atomic force microscopy (AFM), provides valuable insights into the properties and behavior of these materials at a molecular level. This review highlights the applications of SPM in biomolecule imaging and the study of physiological processes, as well as the challenges and potential solutions in biological sample preparation. It also discusses the recent advancements in STM and AFM applications on biomolecules, such as DNA, proteins, and carbohydrates, and their potential applications in fields like drug delivery and biosensors.

Summary: Scanning nonlinear dielectric microscopy (SNDM) is a near-field microwave-based scanning probe microscopy method that has wide applications. It is often combined with contact-mode atomic force microscopy (AFM) for topography imaging and contact force regulation. However, SNDM with intermittent contact AFM may result in a lower signal-to-noise ratio. To improve this, we propose a boxcar averaging based signal acquisition method and demonstrate its enhancement on SNDM combined with peak-force tapping AFM. The proposed method is also applicable to other scanning near-field microwave microscopes.

Summary: Synthetic data play an increasingly important role in nanometrology for development of data processing methods and analysis of uncertainties. This paper reviews methods for generating synthetic data and their applications in scanning probe microscopy, focusing on principles, performance, and applicability. The benefits of using synthetic data in tasks related to improving scanning approaches and estimating reliability of data processing methods are demonstrated, along with analyzing systematic errors common to scanning probe microscopy methods.

Summary: The study revealed that the formation of a chemical bond between a CO molecule and a Cu(111) surface is accompanied by bending of the molecular probe due to van der Waals attraction and Pauli repulsion, resulting in characteristic changes in the vertical force between CO and Cu(111) as a function of molecule-surface distance. Experimental data were successfully reproduced by model calculations, shedding new light on vertical-force extrema in scanning probe experiments.

Summary: In this study, the effect of extracellular matrix (ECM) stiffness on the efficacy of candesartan (CAN) in anti-fibrosis and antioxidant treatment was investigated. The results showed that CAN had the best improvement efficacy in rats with medium-stiffness myocardial tissue. Cell culture substrates mimicking the ECM stiffness of cardiac fibroblasts (CFs) at different stages of myocardial fibrosis were used to study the effects of ECM stiffness on CFs, and it was found that CAN had the most significant anti-fibrosis and antioxidant efficacy on medium-stiffness substrates.

Summary: Epithelial-mesenchymal transition (EMT) is a physiological process essential for embryogenesis and wound healing, but also implicated in pathologies like fibrosis and cancer. Regulation of phosphorylation status can impact cell physiology and gene expression changes during TGFβ1-induced EMT, highlighting the crucial role of intricate crosstalk between signaling cascades in regulating EMT processes.

Summary: Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease with limited understanding of its pathogenesis. Recent studies suggest that sustained lung epithelial injury and fibroblast differentiation play key roles in the development of IPF. Current treatments can slow disease progression but cannot cure it.

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.

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.
