Background: For the present study, we hypothesized that fibrin is an inducer of tissue factor (TF) expression in vascular endothelial cells in vitro and in vivo.
Methods And Results: To test the in vitro aspect of this hypothesis, human umbilical vein endothelial cells (HUVECs) were cocultured with physiologically relevant concentrations of fibrin (0.03 to 1.0 mg fibrin/mL) for various times (0.5 to 24 hours), and TF expression was compared with that in unstimulated HUVECs (media control). Results demonstrated that fibrin induced a time- and dose-dependent increase in TF antigen expression, functional TF procoagulant activity, and TF mRNA in HUVECs.
Conclusions: These studies demonstrate that fibrin can directly regulate TF expression in HUVECs in vitro.

Low fracture toughness, low-temperature degradation (LTD) susceptibility, and inadequate soft tissue integration greatly limit the application of zirconia ceramic abutment. Integrating the "surface" of hard all-ceramic materials into the gingival soft tissue and simultaneously promoting the "inner" LTD resistance and fracture toughness is challenging. Composite ceramics are effective in improving the comprehensive properties of materials.

Background And Aim: Zhilong Huoxue Tongyu Capsule (ZL capsule) has been demonstrated to be an effective and widely-used traditional Chinese medicine (TCM) formula for the treatment of various diseases, especially for atherosclerosis (AS) related cardiovascular and cerebrovascular diseases. Reversal of endothelial-mesenchymal transition (EndMT) plays a crucial role in the cure of AS. But the curative impact of ZL capsule on EndMT remains obscure during the development of AS.

Endothelial cell dysfunction plays a crucial role in the early development of cerebral small vessel disease (CSVD). Arginase-1 (ARG1) is expressed in endothelial cells, and its deficiency may exacerbate cerebrovascular damage by increasing reactive oxygen species (ROS) production, thereby inducing endothelial cell apoptosis. Berbamine (BBM) has shown potential in neuroprotection and cardiovascular disease prevention.

Background: Peritumoral lidocaine infiltration prior to excision is associated with better survival in breast cancer (BC), which led us to hypothesize that innervation to the tumor affects its biology and patient survival. Activity-regulated cytoskeleton-associated protein (ARC) gene expression is known to be regulated by neuronal activity. Therefore, we studied the clinical relevance of ARC gene expression as a surrogate of neuronal activity in BC.

Background: Vascular endothelial growth factor-A (VEGFA) is a key inducer of angiogenesis, responsible for generating new blood vessels in the tumor microenvironment (TME) and facilitating metastasis. Notably, Avastin, which targets VEGFA, failed to demonstrate any significant benefit in clinical trials for breast cancer (BC). This study aimed to investigate the clinical relevance of gene expression in BC.
