Additionally, the results of this research uncovered the presence of 26 immunoregulatory components in MM exosomes (such as oncostatin-M receptor (OSMR), multidrug resistance-associated protein 1 (ABCC1), and the SUMO-1 activating receptor (SAE1)), as well as 16 tumor-derived antigens, including glypican-1, which has been identified in many tumor-derived exosomes and has been recorded as a potentially valuable biomarker for pancreatic cancer [33]. Here, SAE1 is linked to neoplasm.
