Our findings also agree well with other studies on different thymus products such as Thymosin alpha1 (Tα1) which demonstrated significant suppression in the tumor growth of animals bearing lung and breast cancer [13], as well as with other studies treating patients with different types of malignancies including hepatocellular carcinoma [37], non–small-cell lung cancer [14], and melanoma [17]. Here, TAAR1 is linked to breast cancer.
