C-Reactive Protein Signaling Pathways in Tumor Progression

Area of Science:

• Oncology
• Immunology
• Biochemistry

Background:

• Chronic inflammation creates a tumor microenvironment that promotes cancer progression, metastasis, and angiogenesis.
• Inflammatory factors secreted by cells in this microenvironment can induce cancer cell proliferation and survival.
• Identifying the roles of specific inflammatory factors, like C-reactive protein (CRP), is crucial for understanding cancer development.

Purpose of the Study:

• To review the signaling pathways and roles of C-reactive protein (CRP) in various cancer types.
• To explore the association between CRP, inflammation, and the tumor microenvironment.
• To highlight CRP's specific involvement in breast, liver, renal, and pancreatic cancers.

Main Methods:

• Literature review of studies investigating C-reactive protein (CRP) in cancer.
• Analysis of CRP's role in signaling pathways within the tumor microenvironment.
• Examination of CRP's impact on cancer cell proliferation, survival, metastasis, and angiogenesis.

Main Results:

• CRP is implicated in the progression of breast cancer, particularly triple-negative breast cancer (TNBC), enhancing invasiveness and tumor formation.
• CRP promotes angiogenesis and contributes to tumor progression in pancreatic and kidney cancers.
• In liver cancer, CRP influences inflammatory responses and lipid metabolism, and modulates immune cells within the tumor microenvironment.

Conclusions:

• C-reactive protein (CRP) plays a significant role in promoting cancer progression across various cancer types through diverse mechanisms.
• CRP signaling pathways interact with other inflammatory mediators, contributing to the complex relationship between inflammation and cancer.
• Further research into CRP's interactions is crucial for developing targeted cancer therapies and understanding inflammation-driven tumorigenesis.
