Functional diversity and cooperativity between subclonal populations of pediatric glioblastoma and diffuse intrinsic pontine glioma cells.
Vinci, M; Burford, A; Molinari, V; Kessler, K; Popov, S; et al. (OXFORD UNIV PRESS INC, 2018-05-01)The failure to develop effective therapies for pediatric glioblastoma (pGBM) and diffuse intrinsic pontine glioma (DIPG) is in part due to their intrinsic heterogeneity. We aimed to quantitatively assess the extent to which ... -
GDNF-RET signaling in ER-positive breast cancers is a key determinant of response and resistance to aromatase inhibitors.
Morandi, A; Martin, L-A; Gao, Q; Pancholi, S; Mackay, A; et al. (AMER ASSOC CANCER RESEARCH, 2013-06-15)Most breast cancers at diagnosis are estrogen receptor-positive (ER(+)) and depend on estrogen for growth and survival. Blocking estrogen biosynthesis by aromatase inhibitors has therefore become a first-line endocrine ... -
Infant High-Grade Gliomas Comprise Multiple Subgroups Characterized by Novel Targetable Gene Fusions and Favorable Outcomes.
Clarke, M; Mackay, A; Ismer, B; Pickles, JC; Tatevossian, RG; et al. (AMER ASSOC CANCER RESEARCH, 2020-07-01)Infant high-grade gliomas appear clinically distinct from their counterparts in older children, indicating that histopathologic grading may not accurately reflect the biology of these tumors. We have collected 241 cases ... -
