Abstract

BACKGROUND: Metastasis is the leading cause of mortality in luminal subtype breast cancer. While cluster of differentiation (CD)44 has been widely studied, the prognostic relevance of its isoforms particularly the CD44v6/CD44s ratio remains unclear. This study evaluates CD44v6, CD44s, vascular endothelial growth factor (VEGF), and the CD44v6/CD44s ratio as potential prognostic biomarkers for metastasis in luminal breast cancer.METHODS: This case-control study included 38 luminal subtype breast cancer patients (18 with metastasis, 20 without metastasis). Serum levels of CD44v6, CD44s, VEGF, and the CD44v6/CD44s ratio were measured using Enzyme-Linked Immunosorbent Assay (ELISA). Statistical analyses included ROC analysis to determine optimal cut-off points, logistic regression to assess risk factors, and correlation analysis for biomarker relationships.RESULTS: A low CD44v6/CD44s ratio (<0.03) was identified as a significant independent factor for metastasis (adjusted OR 7.0, 95% CI: 1.2–40.6, p=0.03). While serum levels of CD44v6, CD44s, and VEGF were higher in the metastasis group, these individual markers showed a non-significant trend toward association with metastasis. A strong positive correlation was observed between CD44s and VEGF levels (r=0.7, p<0.01).CONCLUSION: The CD44v6/CD44s ratio showed a significant association with metastasis and may have potential as a prognostic marker in luminal breast cancer. Further studies with larger sample sizes are needed to confirm these findings.KEYWORDS: CD44v6, CD44s, VEGF, CD44v6/CD44s ratio, luminal breast cancer, metastasis

Abstract

BACKGROUND: Methanol intoxication is associated with significant morbidity and mortality, particularly when acute kidney injury (AKI) developed. Emerging evidence implicates Endothelin-1 (ET-1) and Nucleotide-binding domain leucine-rich repeat-containing pyrin receptor 3 (NLRP3) inflammasome in renal injury, but their roles in methanol-induced AKI remain unclear. To date, no studies have examined whether hydroxychloroquine or folinic acid, which are known to modulate ET-1 and NLRP3 signaling, could mitigate renal injury in this setting. This study evaluated their therapeutic effects in a rabbit model of methanol-induced AKI.METHODS: The animals subjects were randomly assigned to four groups: control group receiving aquabidest, folinic acid group receiving 2 mg/kg body weight (BW) intraperitoneal folinic acid, hydroxychloroquine group receiving 30 mg/kg BW oral hydroxychloroquine phosphate, and combination group receiving both folinic acid and hydroxychloroquine at the same dosages. Histopathological evaluation of tubular injury scores and immunohistochemical analysis of ET-1 and NLRP3 expression were then conducted.RESULTS: Expressions of ET-1, NLRP3, and tubular injury scores were significantly lower in the hydroxychloroquine, folinic acid, and combination therapy groups compared to the control group (p<0.001). Expression of ET-1 was lowest in folinic acid group (59.38±0.71%), followed by combination group (62.23±1.98%) and hydroxychloroquine group (62.43±1.81%), compared to control group (72.14±1.02%). Expression of NLRP3 was lowest in combination group (58.94±1.05%), followed by folinic acid and hydroxychloroquine group, which showed equal values (60.57±1.38%), compared to control group (72.15±1.02%). Tubular injury scores were also lowest in combination group (27.07±3.16%), followed by hydroxychloroquine group (45.29±1.75%) and folinic acid group (48.38±2.49%), compared to control group (77.15±1.66%).CONCLUSION: Expression of ET-1 and NLRP3, as well as tubular injury scores, are significantly lower in all treatment groups compared to control, suggesting hydroxychloroquine and folinic acid demonstrated renoprotective effects in methanol-induced AKI, likely through modulation of ET-1 and NLRP3 pathways.KEYWORDS: methanol intoxication, acute kidney injury, hydroxychloroquine, folinic acid, endothelin-1, NLRP3 inflammasome, experimental animal models, rabbits
