Aberrant activation of hedgehog (Hh) signaling has been observed in a wide variety of tumors and accounts for more than 25% of human cancer deaths. Inhibitors targeting the Hh signal transducer Smoothened (SMO) are widely used and display a good initial efficacy in patients suffering from basal cell carcinoma (BCC); however, a large number of patients relapse. Though SMO mutations may explain acquired therapy resistance, a growing body of evidence suggests that the non-canonical, SMO-independent activation of the Hh pathway in BCC patients can also account for this adverse effect. In this review, we highlight the importance of glioma-associated oncogene (GLI) transcription factors (the main downstream effectors of the canonical and the non-canonical Hh cascade) and their putative role in the regulation of multiple oncogenic signaling pathways. Moreover, we discuss the contribution of the Hh signaling to malignant transformation and propose GLIs as central hubs in tumor signaling networks and thus attractive molecular targets in anti-cancer therapies.

Sphingosine 1-Phosphate Receptor 5 (S1P5) Knockout Ameliorates Adenine-Induced Nephropathy

Timon Eckes, Sammy Patyna, Alexander Koch, Anke Oftring, Stefan Gauer, Nicholas Obermueller, Stephanie Schwalm, Liliana Schaefer, Jerold Chun, Hermann-Josef Groene, Josef Pfeilschifter

Summary: This study found that S1P(5) deficiency can improve tubular damage and tubulointerstitial fibrosis in a mouse model of adenine-induced nephropathy, and reduce inflammation. Therefore, targeting S1P(5) may be a promising therapeutic target for kidney diseases.

EGFR Signaling in Lung Fibrosis

Fabian Schramm, Liliana Schaefer, Malgorzata Wygrecka

Summary: This review article provides an overview of the ErbB receptor-ligand system and its importance in developmental and physiological processes. It focuses on the role of ErbB receptors and their ligands in maladaptive remodeling of lung tissue, specifically in idiopathic pulmonary fibrosis (IPF). The article discusses the pathways and cellular processes contributing to miscommunication between epithelial and mesenchymal cells in IPF, and reviews in vivo studies on the efficacy of ErbB signaling inhibitors in lung injury models. Additionally, it discusses lessons learned from clinical applications of ErbB1 signaling inhibitors in cancer to inform clinical trials in IPF.

Transcriptional Profiling of Insulin-like Growth Factor Signaling Components in Embryonic Lung Development and Idiopathic Pulmonary Fibrosis

Summary: This study provides a comprehensive transcriptional profile of IGF signaling components in mice during embryonic lung development, bleomycin-induced pulmonary fibrosis, and human IPF lung explants. The findings suggest that Igf1 is upregulated in the lung mesenchyme during late gestation, while Igf1r is downregulated. In lung fibrosis, IGF1 is upregulated while IGF1R is downregulated, and several IGF binding proteins are upregulated. Treatment of IPF lung fibroblasts with recombinant IGF1 leads to myogenic differentiation.

Diverse functions of apolipoprotein A-I in lung fibrosis

Malgorzata Wygrecka, Ioannis Alexopoulos, Daniel P. Potaczek, Liliana Schaefer

Summary: ApoA-I plays an important role in reverse cholesterol transport and also possesses anti-inflammatory and antioxidative functions. Dysfunctional apoA-I or its low abundance can lead to the formation of foam cells in alveolar macrophages. Increased numbers of foam cells have been observed in the lungs of mice exposed to certain substances and in patients with lung fibrosis. Understanding the role of apoA-I in lung fibrosis provides potential avenues for therapeutic development.

Activin A and CCR2 regulate macrophage function in testicular fibrosis caused by experimental autoimmune orchitis

Summary: Experimental autoimmune-orchitis (EAO), a rodent model of chronic testicular inflammation and fibrosis, replicates pathogenic changes seen in some cases of human spermatogenic disturbances. CCR2 and activin A promote fibrosis during testicular inflammation by regulating macrophage function.

Circulating hyaluronic acid signature in CAP and ARDS- the role of pneumolysin in hyaluronic acid shedding

Summary: This study reveals the association between the severity of community-acquired pneumonia (CAP) and acute respiratory distress syndrome (ARDS) with hyaluronan (HA) levels and size in plasma. Increased HA levels are correlated with disease severity, inflammation, endothelial cell activation, and basement membrane destruction, and are associated with increased 28-day mortality. The study also shows that pneumolysin (PLY), a toxin secreted by Streptococcus pneumoniae, induces HA shedding from human pulmonary microvascular endothelial cells (HPMVEC) through reactive oxygen species (ROS) production.

The emerging role of extracellular vesicles as communicators between adipose tissue and pathologic lungs with a special focus on asthma

Sarah Miethe, Daniel P. Potaczek, Stanislawa Bazan-Socha, Melanie Bachl, Liliana Schaefer, Malgorzata Wygrecka, Holger Garn

Summary: Extracellular vesicles (EVs) have gained attention for their role in intercellular signaling, particularly in the connection between adipose tissue (AT) and the lung in diseases such as obesity-associated asthma and lung cancer-associated cachexia. Studies have shown both pathogenic and protective effects of EVs in these diseases, with AT-derived EVs playing a potential therapeutic role. Further research is needed to better understand the role of EVs in disease development and organ interconnectivity.

Basement membrane product, endostatin, as a link between inflammation, coagulation and vascular permeability in COVID-19 and non-COVID-19 acute respiratory distress syndrome

Summary: Immune cell recruitment, endothelial cell barrier disruption, and platelet activation are common in lung injuries like COVID-19-induced ARDS. In this study, we investigated the role of endostatin, a bioactive fragment of the basement membrane protein collagen XVIII alpha 1, on cellular functions associated with ARDS. Our results showed that endostatin enhanced neutrophil and platelet activity, as well as induced microvascular barrier disruption.
