MMP9-L

MMP9 expression and presence of macrophages M0 were positively correlated, while naïve B cells, activated dendritic cells, monocytes and plasma cells were negatively correlated. The results were confirmed by brightfield and multiplex fluorescence immunohistochemistry using stained bladder cancer and normal tissue.

Although cetuximab is the sole anti-EGFR approved by the Food and Drug Administration for treating HNC patients.its response rates are modest...Bioinformatic analysis revealed that BCL2low, IL6low and MMP9low HNC biospecimens are enriched with epithelial cell differentiation gene set, and CASP8high cohort is enriched with extrinsic apoptosis. Altogether, this study emphasizes the therapeutic potential of targeting the apoptotic and inflammatory machineries in HNC using EMD37.

Interestingly, cells treated with CNT Mod exhibited higher cytotoxic, apoptotic, anti-migratory, and anti-angiogenic potentials relative to CNT-treated cells. In conclusion, targeted nano-therapy of encapsulated cisplatin and anthocyanin-loaded carbon nanotubes coated with chitosan conjugated folic acid can efficiently combat breast and liver cancers by sustained release, in addition to its apoptotic, antioxidant, anti-inflammatory, anti-metastatic, and anti-angiogenic effects.

Furthermore, patients with a higher expression of LPAL2 and lower expression of MMP9 (LPAL2-high/MMP9-low) had a higher survival rate than those with other combinations. Collectively, our findings establish LPAL2 as a novel tumor suppressor in HCC, and suggest targeting LPAL2 and MMP9 as a therapeutic approach for the treatment of HCC.

In this study, we identified that MMP9-High could be potentially considered a novel biomarker used to ascertain the improved prognosis of SCLC patients after cisplatin treatment. Furthermore, we indicated that the tumor immune microenvironment of MMP9-High SCLC is mainly characterized by a large number of infiltrated activated immune cells as well as activated immune-related pathways.

Finally, using flow cytometry, we showed that MMP9 was expressed by tumor-infiltrating neutrophils. In conclusion, circulating MMP9 is predictive of bevacizumab efficacy and is released by tumor-infiltrating neutrophils.

However, the prognostic value of MMP9 was limited to only the HR negative and CTC epithelial-to-mesenchymal transition positive subgroups. Thus, analyzing MMP9 tumor expression may help identify patients with increased risk of disease recurrence in these subgroups.
