Cathepsin B as a potential serum biomarker for early diagnosis and progression of diabetic foot ulcer complicated with peripheral vascular disease
CTSB is proposed as a potential serum biomarker for early diagnosis of diabetic foot ulcer (DFU) complicated with peripheral vascular disease (PVD). The study reveals that CTSB levels correlate with the severity of DFU, as indicated by the Wagner grade, and its expression is linked to key clinical indicators. Functional assays demonstrate that CTSB influences angiogenesis in vascular endothelial cells, suggesting its role in disease progression. This research highlights the potential of CTSB for non-invasive monitoring and early intervention in DFU patients.

Fibrinogen alpha and beta chains as non-invasive predictors of hepatocellular carcinoma progression
Fibrinogen alpha (FGA) and beta (FGB) chains have been identified as promising non-invasive biomarkers for hepatocellular carcinoma (HCC), showing improved diagnostic accuracy compared to traditional markers like α-fetoprotein (AFP). The study highlights significant downregulation of these proteins in HCC, correlating with disease progression and overall survival rates. Their consistent expression patterns across various stages of HCC suggest their potential utility in early diagnosis and monitoring of the disease. The findings underscore the importance of further research to validate these biomarkers in clinical settings.
