RAB27B and neoplasm: When expressed at physiological levels, miRNA-193a-3p mediates tumor-suppressive effects through Epidermal Growth Factor Receptor (EGFR) signaling, enhances apoptosis by inhibition of MCL1, and suppresses tumor cell migration and invasion through small GTPase Rab27B or Erb-B2 Receptor Tyrosine Kinase 4 (ERBB4) and S6K2 [63,64,65,66].
