Article Abstract

The transforming growth factor-β (TGF-β) is known to regulate a large number of biological processes and is involved in various aspects of tumor development. Recent studies have shown that the biogenesis of miRNAs can be regulated by TGF-β signaling directly via Smad-dependent mechanisms and/or other unknown mechanisms, which may induce autoregulatory feedback loops in response to the activation of TGF-β signaling, influencing the fate of tumor cells. In this chapter, we summarize the currently described mechanisms underlying TGF-β's regulation of miRNA biogenesis, and the functional role of TGF-β-regulated miRNAs in tumor initiation, epithelial-mesenchymal transition, and tumor microenvironment modulation. Finally, we introduce methods to study TGF-β-regulated miRNAs and their functions in tumor progression and metastasis using an example of publication from our lab demonstrating the presence of a TGF-β-miR-34a-CCL22 signaling axis, which serves as a potent etiological pathway for the development of hepatocellular carcinoma venous metastases.

Purpose: Real‑time magnetic resonance-guided radiation therapy (MRgRT) integrates MRI with a linear accelerator (Linac) for gating and adaptive radiotherapy, which requires robust image‑quality assurance over a large field of view (FOV). Specialized phantoms capable of accommodating this extensive FOV are therefore essential. This study compares the performance of four commercial MRI phantoms on a 0.

Nuclear receptors (NRs) are a superfamily of ligand-activated transcription factors that regulate gene expression in response to metabolic, hormonal, and environmental signals. These receptors play a critical role in metabolic homeostasis, inflammation, immune function, and disease pathogenesis, positioning them as key therapeutic targets. This review explores the mechanistic roles of NRs such as PPARs, FXR, LXR, and thyroid hormone receptors (THRs) in regulating lipid and glucose metabolism, energy expenditure, cardiovascular health, and neurodegeneration.

Organotypic Culture of Adult Vascularized Porcine Retina Explants In Vitro on Nanotube Scaffolds.

Biol Proced Online

September 2025

Division of Surface Physics, Department of Physics and Earth System Sciences, University of Leipzig, Linnéstr. 5, 04103, Leipzig, Germany.

Background: Organotypic long-term cultivation of vascularized retina explants is a major challenge for application in drug development, drug screening, diagnostics and future personalized medicine. With this background, an assay and protocol for organotypic culture of vascularized retina explants in vitro with optimum tissue integrity preservation is developed and demonstrated.

Methods: Morphological, histologic and biochemical integrity as well as viability of vascularized retina explants are compared as function of cultivation time for differently structured nanotube scaffolds.

Widefield acoustics heuristic: advancing microphone array design for accurate spatial tracking of echolocating bats.

BMC Ecol Evol

September 2025

Lehrstuhl für Zoologie, TUM School of Life Sciences, Technical University of Munich, Liesel-Beckmann Strasse 4, Freising, 85354, Germany.

Accurate three-dimensional localisation of ultrasonic bat calls is essential for advancing behavioural and ecological research. I present a comprehensive, open-source simulation framework-Array WAH-for designing, evaluating, and optimising microphone arrays tailored to bioacoustic tracking. The tool incorporates biologically realistic signal generation, frequency-dependent propagation, and advanced Time Difference of Arrival (TDoA) localisation algorithms, enabling precise quantification of both positional and angular accuracy.

The stress urinary incontinence (SUI) is a difficulty in urology and current sub-urethral sling treatments are associated with inflamation and recurrence. In this study, we developed a novel tissue-engineered sling with myogenic induced adiposederived stem cells (MI-ADSCs) sheets induced by 5-Aza and combined with electrospun scaffolds of silk fibroin and poly(lactide-co-glycolide) (SF/PLGA) for the treatment of stress urinary incontinence. MI-ADSCs increased α-SMA, MyoD and Desmin the mRNA and protein expression.
