Objective: To explore the expression of vascular endothelial growth factor (VEGF) C and D in gastric cancer and its relationship with tumor angiogenesis and lymph node metastasis.
Methods: Immunohistochemistry(SABC) and real-time PCR were used to detect the expression of VEGF-C, VEGF-D protein and mRNA in 32 gastric cancer tissues and 32 normal gastric tissues.
Results: The positive expression rate of VEGF-C and VEGF-D in gastric cancer tissue was significantly higher than that of normal gastric tissues (P<0.01), the expression of VEGF-C and VEGF-D in the gastric cancer group and the lymph node metastasis group were significantly different (P<0.05). The expression of VEGF-C and VEGF-D in gastric carcinoma was positively correlated with lymph node metastasis (P<0.01), the expression of VEGF-C and VEGF-D in well-differentiated carcinoma, moderately differentiated carcinoma and poorly differentiated carcinoma was statistically different (P<0.05). VEGF-C and VEGF-D expressions in gastric cancer cells were not related to the patient's age, sex, and lymph node distant metastasis (P>0.05).
Conclusion: The non-intake high expression of VEGF-C and VEGF-D in gastric cancer cells is closely related to lymph node metastasis. They serve as the important reference indicator to assess the prognosis in gastric cancer patients.

Introduction: We investigated the specific factors driving abnormal angiogenesis in Alzheimer's disease (AD) and its role in cerebrovascular lesions and neurodegeneration.
Methods: We assessed cerebrovascular pathologies, amyloid-beta (Aβ), and tau pathologies in post mortem human brains and detected 12 angiogenic factors in cerebrospinal fluid (CSF) from the China Aging and Neurodegenerative Disease Initiative (CANDI) cohort.
Results: We observed severe blood-brain barrier damage and elevated levels of the vascular marker CD31 in human AD brains, which had a stronger correlation with tau pathology than Aβ pathology.

Background: Atrial fibrillation (AF) is the most prevalent form of sustained cardiac arrhythmia, with vascular endothelial growth factor (VEGF) increasingly recognized for its potential role in the pathogenesis of AF through mechanisms involving atrial remodeling, inflammation, and fibrosis. This systematic review aims to synthesize available evidence on the association between VEGF and AF, exploring the implications of VEGF as a biomarker and therapeutic target.
Methods: We conducted a comprehensive search across PubMed, Embase, and Web of Science until November 10 2024, selecting studies based on pre-defined criteria that involve adults with AF and measurements of VEGF levels.

Background: Chronic kidney disease (CKD) counts acute kidney injuries (AKI) as one of its many underlying causes. Lymphatic vessels are important in modulating inflammation post-injury. Manipulating lymphatic vessel expansion thus has the potential to alter CKD progression.

Aim: Atezolizumab/bevacizumab is a first-line therapy for unresectable hepatocellular carcinoma (HCC). Among several adverse events, grade ≥2 proteinuria is considered a significant adverse event that may cause bevacizumab interruption. Studies have shown that proteinuria might predict improved prognosis, although data are scarce and the association remains controversial, and the mechanisms and predictive factors remain unclear.

Article Synopsis
- * Results indicate that higher genetically predicted levels of VEGF-A and VEGF-D are linked to an increased risk of developing atrial fibrillation, with VEGF-D being particularly significant.
- * The findings suggest that elevated VEGF-D levels may causally contribute to the risk of atrial fibrillation, highlighting its potential as a target for further research and intervention.
