CD47 expression

Subsequently, we employed reverse transcription quantitative polymerase chain reaction (RT-qPCR) and flow cytometry analysis to examine and compare CD47 expression across human ovarian surface epithelial cell line (HOSE), SKOV3, and ES2 cells and to characterize the changes in CD47 expression in SKOV3 and ES2 cells after cisplatin treatment...CD47 is highly expressed in ovarian cancer, and NACT increases the expression of CD47, which may contribute to tumor immune evasion. It is possible that platinum-based chemotherapy may result in elevated CD47 mRNA expression and cell surface CD47 protein expression.

Advanced research hints that SPAG4 might achieve immune evasion by increasing CD47 expression, consequently reducing phagocytosis. These findings highlight SPAG4 as a potential GBM therapeutic target and emphasize the complexity of the immune microenvironment in GBM progression.

CD47 expression in CRC was associated with the activation of several oncogenic pathways and an immune-engaged TME. Our findings may provide valuable information for considering new therapeutic strategies targeting innate immune checkpoints in CRC.

However, treatment efficacy is varied in pre-clinical and clinical models due to various challenges such as off-target effects. This review emphasizes the diverse functionality of macrophages in normal and cancerous tissue, while also emphasizing the importance of macrophage targeting and their clinical significance.

Our study demonstrates that PUS7 promotes the inhibition of CD47 and inhibits metastasis of PTC cells by regulating the ψ modification of pre-miR-8082. These results suggest that PUS7 and ψ pre-miR-8082 may serve as potential targets and diagnostic markers for PTC metastasis.

Lastly, microglia reactivity increased with age in association with the changes in C1q and CD47. Together, these results suggest disruption in the balance of "eat me" and "don't eat me" signals during normal aging, biasing microglia toward increased reactivity and phagocytosis of myelin, resulting in cognitive deficits.

All authors had full access to the data and vouched for the completeness and accuracy of the data and analyses, and adherence of the study to the protocol (online only). Consent All patients provided written informed consent before study entry.

In addition, in vivo experiments showed that the anti-CD47 mAb AK117 significantly inhibited the growth of subcutaneous xenograft tumors in SCID mice compared to the control antibody IgG. Our results indicate that targeting CD47 monoclonal antibodies is a potential therapeutic strategy for NKTCL.

Decreased tumor weights and volumes were observed in mice injected with CD47-deficient CCA clones. This revealed a significant role for CD47 in CCA, with a focus on protecting cancer cells from macrophage phagocytosis.

Unlike CD47-targeted agents, ES004-B5 exhibits an excellent safety profile in nonhuman primates. ES004-B5 has potential to be an important backbone for SIRPα-based combination therapy and/or bispecific antibodies, which will likely overcome the limitations of CD47-targeted agents encountered in clinical settings.

Infiltration by large numbers of CD68-IT cells was much more common among patients with a high expression of CD47 in tumor cells. A high level of infiltration by CD68-ST cells was associated with a worse prognosis, and a high level of infiltration by CD68-ST cells was associated with a lower risk of death from cancer.
