Gross et al. [29] demonstrated that YKT6 depletion decreased TSG101, WNT3A and VPS26/35 levels in exosomes secreted by human embryonic kidney HEK293 cells [29], and Ruiz-Martínez et al. [30] observed reduced TSG101 levels associated to exosomes after YKT6 depletion in human lung cancer A549 cells [30]. Here, TSG101 is linked to lung cancer.
