Article Abstract
Objective: To explore the underlying molecular mechanism of Notch1/cadherin 5 (CDH5) pathway in modulating in cell malignant behaviors of gastric cancer (GC).
Methods: We performed bioinformatic analyses to screen the potential target genes of Notch1 from cadherins in GC. Western blot and RT-PCR were conducted to detect CDH5 expression in GC tissues and cells. We utilized chromatin immunoprecipitation (CHIP) assays to assess the interaction of Notch1 with CDH5 gene. The effects of Notch1/CDH5 axis on the proliferation, invasion, migration and vasculogenic mimicry in GC cells were evaluated by EdU, wound healing, transwell, and tubule formation assays.
Results: Significantly increased CDH5 expression was found in GC tissues compared with paracancerous tissues and associated to clinical stage and poor overall survival (OS) in patients with GC. Notch1 positively regulate the expression of CDH5 in GC cells. CHIP assays validated that CDH5 was a direct target of Notch1. In addition, Notch1 upregulation enhanced the proliferation, migration, invasion and vasculogenic mimicry capacity of GC cells, which could be attenuated by CDH5 silencing.
Conclusions: These results indicated Notch1 upregulation enhanced GC malignant behaviors by triggering CDH5, suggesting that targeting Notch1/CDH5 axis could be a potential therapeutic strategy for GC progression.

Background: Small artery remodeling and endothelial dysfunction are hallmarks of hypertension. Evidence supports a likely causal association between cardiovascular diseases and endothelial-to-mesenchymal transition, a cellular transdifferentiation process in which endothelial cells (ECs) partially lose their identity and acquire mesenchymal phenotypes. EC reprogramming represents an innovative strategy in regenerative medicine to prevent deleterious effects induced by cardiovascular diseases.

Background And Aims: Platelet-Derived Growth Factor (PDGF)-C plays a significant role in kidney fibrosis, angiogenesis, and hypertension. While its involvement in the healing of damaged glomerular capillaries is well recognized, its function in kidney peritubular capillaries (PTCs) remains less understood. Therefore, this study investigates the role of PDGF-C in PTCs under both homeostatic conditions and experimentally angiotensin II (AngII)-induced hypertension.

Lung cancer remains a critical global health concern, characterized by the highest incidence and mortality rates among all cancers. Due to its heterogeneity and complexity, the molecular mechanism underlying lung cancer occurrence and progression needs to be further investigated. KCTD10 has been implicated in malignant phenotypes of several tumors, but the role of KCTD10 in lung cancer remains largely unexplored.

Introduction: The neuronally differentiated key sensory and regulatory cells of the macula densa (MD) were recently identified to control resident progenitor cells and endogenous kidney tissue remodeling and regeneration. Among the many MD-derived secreted angiogenic, growth, and extracellular matrix remodeling factors, cell communication network 1 (CCN1) is a known positive modulator of angiogenesis. This study aimed to validate and characterize the angiogenic potential and mechanisms of MD-derived biologicals including CCN1 in control healthy and disease conditions.

Aims: Angiogenesis, a tightly regulated process involving dynamic endothelial cell (EC) proliferation, is critical in both physiological and pathological contexts such as ocular neovascular disorders. While Notch signaling is known to regulate angiogenesis, its downstream molecular mechanisms remain incompletely understood.
Main Methods: Gene-modified mice with a Cdh5-Cre transgene were generated to block Notch signaling in ECs.
