The present review outlines several evidence-related insights into the molecular mechanisms of NB pathogenesis, focusing on genetic drivers (e.g., MYCN amplification) and disrupted signaling pathways (PI3K/Akt/mTOR; Notch; Jak2/STAT3), as well as on the tumor microenvironment’s role in progression and resistance. The gene discussed is MTOR; the disease is neoplasm.
