Cathepsin B: Plasma Expression and Concentration in Non-Hodgkin Lymphoma Patients

Year: 2025

Type: article

Abstract: Numerous studies point to the significance of cathepsin B (CTSB) in the development of carcinoma. Therefore, the aim of this pilot study was to investigate the levels of cathepsin B (CTSB) and the expression of CTSB mRNA in the plasma of non-Hodgkin lymphoma (NHL) patients. Methods: The study included 44 newly diagnosed NHL patients and 35 healthy volunteers comprising the control group. CTSB in the plasma samples were detected using the enzyme-linked immunosorbent assay (ELISA). Results: The level of CTSB was significantly higher in NHL patients compared to control subjects: 15.28 (11.68–17.23) versus 11.57 (10.12–13.41), p = 0.003. In addition, a positive correlation between plasma CTSB mRNA and CTSB after therapy was observed (rho = 0.591, p = 0.026). Regarding redox parameters, we found a negative correlation between CTSB and the total antioxidant status (TAS) (rho = −0.499, p = 0.035), as well as a positive correlation with the total oxidant status (TOS) (rho = 0.576, p = 0.012). Conclusions: Targeting CTSB might have significant clinical relevance in the diagnostics of NHL.
