It was observed that ARFRP1, ARL1, ARL10, ARL13B, ARL15, ARL2, ARL3, ARL4A, ARL4D, ARL5A, ARL5C, ARL8B, and TRIM23 showed low expression in endometrial cancer compared to the control, while ARF1, ARF3, ARF4, ARF5, ARF6, ARL11, ARL14, ARL16, ARL4C, ARL5B, ARL8A, ARL9, and SAR1B were overexpressed [53]. This evidence concerns the gene ARL2 and endometrial cancer.
