SAMD4B and breast carcinoma: Our results revealed that the β-catenin transcript was significantly enriched in SAMD4B-immunoprecipitates compared to control IgG-immunoprecipitates in both MCF-7 and MDA-MB-231 breast cancer cells (Figure 6G,H), demonstrating a specific physical interaction between SAMD4B protein and β-catenin mRNA.
