Endothelial tip cells (ETCs) located at growing blood vessels display high morphological dynamics and associated intracellular Ca activities with different spatiotemporal patterns during migration. Examining the Ca activity and morphological dynamics of ETCs will provide an insight for understanding the mechanism of vascular development in organs, including the brain. Here, we describe a method for simultaneous monitoring and relevant analysis of the Ca activity and morphology of growing brain ETCs in larval zebrafish. For complete details on the use and execution of this protocol, please refer to Liu et al. (2020).

Background: This study tested the hypothesis that extracorporeal shockwave therapy (ECSWT) effectively rescues critical limb ischemia (CLI) in mice through the upregulation of GPR120, which protects against inflammation and angiogenesis to restore blood flow in the ischemic area.

Methods And Results: Compared with the control, ECSWT-induced GPR120-mediated anti-inflammatory effects significantly suppressed the expression of inflammatory signaling biomarkers (TAK1/MAPK family/NF-κB/IL-1β/IL-6/TNF-α/MCP-1) in HUVECs, and these effects were abolished by silencing GPR120 or by the GPR120 antagonist AH7614 (all P < 0.001).

Angiotensin-Converting Enzyme 2 Enhances Autophagy via the Consumption of miR-326 in a Mouse Model of Acute Lung Injury.

Biochem Genet

Department of Pulmonary Disease, Shanghai Municipal Hospital of Traditional Chinese Medicine, Shanghai University of Traditional Chinese Medicine, Shanghai, 200071, China.

Angiotensin-converting enzyme 2 (ACE2) has been reported to exert a protective effect in acute lung injury (ALI), though its underlying mechanism remains incompletely understood. In this study, ACE2 expression was found to be upregulated in a mouse model of ALI induced by lipopolysaccharide (LPS) injection. ACE2 knockdown modulated the severity of ALI, the extent of autophagy, and the mTOR pathway in this model.

Transcriptome of Anaplastic Thyroid Cancer Reveals Two Molecular Subtypes with Distinct Tumor Microenvironment and Prognosis.

Thyroid

January 2025

Department of Molecular Medicine and Biopharmaceutical Sciences, Graduate School of Convergence Science and Technology, Seoul National University, Gwanak-gu, Republic of Korea.

Although patients with anaplastic thyroid cancer (ATC) generally have a poor prognosis and there are currently no effective treatment options, survival and response to therapy vary between patients. Genomic and transcriptomic profiles of ATC have been reported; however, a comprehensive study of the tumor microenvironment (TME) of ATC is still lacking. This study aimed to elucidate the TME characteristics associated with ATC and their prognostic implications.

Investigation of Genomic and Transcriptomic Risk Factors of Clopidogrel Response in African Americans.

Clin Pharmacol Ther

January 2025

Department of Pharmacology, Center for Pharmacogenomics, Feinberg School of Medicine, Northwestern University, Chicago, Illinois, USA.

Clopidogrel, an anti-platelet drug, is used to prevent thrombosis after percutaneous coronary intervention. Clopidogrel resistance results in recurring ischemic events, with African Americans (AA) suffering disproportionately. The aim of this study was to discover novel biomarkers of clopidogrel resistance in African Americans using genome and transcriptome data.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the production of autoantibodies and damage to multiple organs. Glomerulonephritis, a manifestation involving glomerular deposition of immune complexes and complement components, significantly contributes to disease morbidity. Although the endosomal single-stranded RNA sensor TLR7 is known to drive glomerulonephritis by promoting autoantibody production in B cells, the contribution of macrophage TLR7 responses to glomerulonephritis remains poorly understood.
