MEG3 is a maternally expressed imprinted gene suggested to function as non-coding RNA. Our previous studies suggest that has of tumor suppression. The suppressor p53 plays central role in suppression and mediates the functions many other suppressors. Therefore, we hypothesized through activation p53. We found transfection expression constructs for its isoforms results significant increase protein levels dramatically stimulates p53-dependent transcription from p53-responsive promoter. Using...

Patients with glioblastoma (GBM) have a dismal prognosis. Nearly all will relapse no clear standard of care for recurrent disease (rGBM). Approximately 50% patients tumors harboring epidermal growth factor receptor (EGFR) amplification. The antibody-drug conjugate depatuxizumab mafodotin (depatux-m) binds cells EGFR amplification, is internalized, and releases microtubule toxin, killing the cell.

BACKGROUND Epidermal growth factor receptor ( EGFR ) alterations are associated with multiple cancers. Current EGFR‐directed therapies have led to increased efficacy but specific side effects. The antibody‐drug conjugate depatuxizumab mafodotin (depatux‐m) targets a monoclonal antibody linked cytotoxin, and is highly tumor‐specific. METHODS This phase 1/2 study evaluated the safety, pharmacokinetics, of depatux‐m in patients who had advanced solid tumors known wild‐type overexpression,...
