Role of caprin-1 in carcinogenesis

Area of Science:

• Molecular Biology
• Oncology
• Gene Regulation

Background:

• RNA-binding proteins regulate gene expression post-transcriptionally.
• Cytoplasmic activation/proliferation-associated protein-1 (caprin-1) is an RNA-binding protein involved in cell cycle control.
• Caprin-1 collaborates with other RNA-binding proteins like RasGAP SH3-domain-binding protein 1 and fragile X mental retardation protein.

Purpose of the Study:

• To review the role of caprin-1 in tumorigenesis.
• To highlight caprin-1's potential as a biomarker and therapeutic target.

Main Methods:

• Literature review of studies on caprin-1 and its functions.
• Analysis of caprin-1's involvement in cell proliferation, immune checkpoint regulation, and stress granule formation.

Main Results:

• Caprin-1 promotes tumorigenesis by activating cell proliferation and upregulating immune checkpoint proteins.
• Caprin-1 contributes to chemo- and radioresistance through stress granule formation.
• Caprin-1 is implicated in various clinical malignancies.

Conclusions:

• Caprin-1 is a putative oncogenic protein with significant impact on tumorigenesis.
• Caprin-1 presents potential as a biomarker and therapeutic target for cancer treatment.
