| Vemurafenib | Melanoma | Predictive | D | Supports Resistance | 4 | accepted | EID1660A375 melanoma cells containing an inducible shRNA for STAG3 were grown as xenograft tumors in nude mice. The mice in which STAG3 was silenced had tumors that were less sensitive to vemurafenib-induced… (full text at CIViC) PMID 27500726 · Shen et al., 2016 · Open in CIViC | civic |
