Abstract Antibody-Drug Conjugates (ADC) have revolutionized the treatment of several tumors, and extensive research is being devoted to the identification of predictive biomarkers. These are particularly sought after in fields, like breast cancer, in which multiple ADCs with identical target but different payloads have been approved. NF1 is a tumor suppressor widely mutated across several cancers, best characterized as an inhibitor of RAS signaling.

Abstract Caloric Restriction (CR) has established anti-cancer effects, but its clinical relevance and molecular mechanism remain largely undefined. Here, we investigate CR’s impact on several mouse models of Acute Myeloid Leukemias, including Acute Promyelocytic Leukemia, a subtype strongly affected by obesity. After an initial marked anti-tumor effect, lethal disease invariably re-emerges. Initially, CR leads to cell-cycle restriction, apoptosis, and inhibition of TOR and insulin/IGF1 signaling.

Abstract The gene neurofibromatosis 1 (NF1) is increasingly recognized as a key somatic driver of cancerogenesis, in addition to its well-known role as the germline determinant of the onco-developmental syndrome Neurofibromatosis. NF1 is best characterized as a negative regulator of RAS activation, but several lines of evidence suggest that it may have additional, poorly characterized functions.
