Synergistic Combination of Novel Tubulin Inhibitor ABI-274 and Vemurafenib Overcomes Vemurafenib Acquired Resistance in BRAFV600E Melanoma

Abstract excerpt

Acquired clinical resistance to vemurafenib, a selective BRAF(V600E) inhibitor, arises frequently after short-term chemotherapy. Because inhibitions of targets in the RAF-MEK-ERK pathway result in G(0)-G(1) cell-cycle arrest, vemurafenib-resistant cancer cells are expected to escape this cell-cycle arrest and progress to the subsequent G(2)-M phase. We hypothesized that a combined therapy using vemurafenib with a...
