Article Title: Neutrophil Biomarkers Can Predict Cardiotoxicity of Anthracyclines in Breast Cancer
doi: 10.3390/ijms25179735
Figure Lengend Snippet: PGLYRP1, CAMP, MMP9, and CEACAM8 mRNA expression levels are increased in the blood of breast cancer patients treated with DOX-based chemotherapy after the 1st cycle (T1) of DOX-based chemotherapy in comparison with the baseline (T0). ( A ) Histogram showing the ΔCt values of PGLYRP1, CAMP, MMP9, and CEACAM8 in PBMCs of patients with cardiotoxicity (n = 16) and patients without cardiotoxicity (n = 16). Each dot represents one sample, and the mean ± SD for each group is indicated. ( B ) Fold change (2^-ΔΔCt) for each of the examined genes comparing T1 and T2, considering the T0 as a calibrator. ( C ) Receiver operating characteristic (ROC) curves for the ability of blood levels of the four mRNAs to predict DOX-induced cardiotoxicity in breast cancer. NCTX, non-cardiotoxicity; CTX, cardiotoxicity; PGLYRP1, peptidoglycan recognition protein 1; CAMP, cathelicidin antimicrobial peptide; MMP9, matrix metallopeptidase; CEACAM8, carcinoembryonic antigen-related cell adhesion molecule 8. p -value, * < 0.001, ** < 0.01, *** > 0.1.
Article Snippet: We used the following ELISA kits and plasma dilutions: Human PGRPs/PGLYRP1 (Invitrogen# EHPGLYRP1, detection range: 6.14–1500 pg/mL, 1:100 diluted); Human CAMP/LL-37 (MyBioSource, # MBS167379, detection range 0.2–60 ng/mL, undiluted samples), Human CEACAM8/CD66B (MyBioSource, Cat# MBS2024215, detection range 15.62–1000 pg/mL, undiluted samples), Human MMP-9 (R and D Systems, #DMP900, detection range: 0.31–20 ng/mL, 1:100 diluted).
