In recent years, a number of researchers have reported that AHNAK1 is differentially expressed and has a variety of functions in different types of cancer, including pancreatic cancer [13], gastric cancer [14], lung cancer [15, 16], breast cancer [17–23], melanoma [24, 25], oral and laryngeal carcinoma [26–28], clear cell renal cell carcinoma [29–31], meningioma [32], and acute lymphocytic leukemia [33].
