This study was undertaken to evaluate the anticancer effects of Friedelin triterpenoid against the human AML-196leukemia cells. CCK-8 assay was used to determine cell viability. DAPI staining was used for the assessment of apoptosis. Annexin V/propidium iodide (PI) analysis was employed for the detection of percentage of apoptosis. Transwell assays were used for cell migration and invasion. Western blotting was used for the determination of protein expression. The results showed Friedelin inhibited the proliferation of the human AML-196 cells with little effects on the normal cells. Investigation of the underlying mechanisms showed that Friedelin induced apoptosis in AML-196 cells. Friedelin-induced apoptosis was linked with upregulation of cleaved caspase-3, 8 and 9, as well as cleaved PARP. The Bax protein levels were increased and of Bcl-2 were decreased. Transwell assays showed that Friedelin suppressed the migration and invasion of the AML-196leukemia cells. Additionally, Friedelin also blocked the MEK/ERK and PI3K/AT signalling cascades dose-dependently. Taken together, Friedelin may prove beneficial in the treatment of leukemia. Taken together, Friedelin may prove beneficial in the treatment of leukemia. The development of erratic distribution of cervical metastases from oral cavity squamous cell carcinoma (OSCC) bypassing the typical metastatic pattern can possibly challenge the role of the classic neck dissection. The purpose of this study was to assess the role of lymphoscintigraphy (LS) and radio-guided neck dissection as a simple and widely accessible method with a favorable cost/benefit ratio, able to improve the OSCC staging and possibly to tailor the surgical approach to cervical lymph node dissectio
