STOM is another of the main upregulated proteins whose role in cervical cancer is unknown, but it has been proposed as a new exosomal marker after being identified in the EVs of breast, lung, and ovarian cancer cells, as well as in the EVs of body fluids such as blood plasma, uterine fluid, ascitic fluid, and gastric juice [51,52]. The gene discussed is STOM; the disease is cervical cancer.
