G3BP1 mRNA levels are increased in mouse and human TSC tumors [angiomyolipomas (AML), subependymal giant cell astrocytoma (SEGA), subependymal nodules (SEN)] (Kosmas et al., 2021) and in breast cancer (Winslow et al., 2013; Zhang et al., 2021). Here, G3BP1 is linked to subependymal giant cell astrocytoma.
