G3BP2 and breast neoplasm: In previous work, we found that the G3BP2 is involved in the generation of breast tumor‐initiating cells, acting through SART3 (squamous cell carcinoma antigen recognized by T cells 3) and the pluripotency transcription factors Oct‐4 (octamer‐binding transcription factor 4) and Nanog (Nanog homeobox) [11].
