Abstract: The retinoic acid (RA) signaling pathway is crucial for many biological processes. The RA
transporter, Cellular Retinoic-Acid Binding Protein 2 (CRABP2), is abnormally expressed in various
tumor types. CRABP2 presents significant effects on tumorous behaviors and functions, including cell
proliferation, apoptosis, invasion, migration, metastasis, and angiogenesis. The tumorigenesis mechanism
of CRABP2, as both suppressor and promotor, is complicated, therefore, there remains the need
for further investigation. Elucidating the regulating mechanisms in a specific stage of the tumor could
facilitate CRABP2 to be a biomarker in cancer diagnosis and prognosis. Besides, clarifying the pathways
of CRABP2 in cancer development will contribute to the gene-targeted therapy. In this review,
we summarized the expression, distribution, and mechanism of CRABP2 in solid tumors. Illuminating
the CRABP2 signaling pathway may benefit understanding the retinoid signaling pathway, providing a
useful biomarker for future clinical trials.
