Abstract

Purpose: Corticosteroids induce apoptosis in the malignant lymphoid cells and are critical component of combination therapy for acute lymphoblastic leukemia (ALL). Several genome-wide microarray studies showed major implication of proapoptotic Bim in mediating corticosteroid-related resistance in leukemia cells. Experimental Design: We investigated Bim gene polymorphisms and their association with childhood ALL outcome, and the mechanism underlying the observed finding. Results: Lower overall survival (OS) was associated with BimC29201T located in Bcl-2 homology 3 (BH3) domain (P = 0.01). An association remained significant in multivariate model (P = 0.007), was more apparent in high-risk patients (P = 0.004) and patients treated with dexamethasone (P = 0.009), and was subsequently confirmed in the replication patient cohort (P = 0.03). RNA analysis revealed that C29201T affects generation of γ isoforms (γ1) that lack proapoptotic BH3 domain. The phenotypic effect was minor suggesting the influence of additional factors that may act in conjunction with Bim genotype. Combined analysis with Mcl gene polymorphism (G-486T) revealed profound reduction in OS in individuals with both risk genotypes (P < 0.0005 in discovery and P = 0.002 in replication cohort) and particularly in high-risk patients (P ≤ 0.008). Conclusions: Increased expression of prosurvival Mcl1 and presence of Bim isoforms lacking proapoptotic function might explain marked reduction of OS in a disease and dose-dependent manner in ALL patients carrying Bim- and Mcl1-risk genotypes.

  • Patients with a CC allele have greater sensitivity to corticosteroid treatment and an increased incidence of osteonecrosis.

    “The importance of gauging treatment dose with allelic expression is typified by patients with a CC allele having a greater sensitivity to corticosteroid treatment and an increased incidence of osteonecrosis [39].”

    From Thrombospondin-1, BIM and CFH polymorphisms and response to anti-VEGF treatment in neovascular age- related macular degeneration patients (2024) · cites this paper as [39]

    The Results (page unavailable) associate the BIM C29201T genotype with outcomes during corticosteroid treatment: TT patients had the lowest overall survival, including among those receiving dexamethasone. This does not establish that CC patients are more sensitive to corticosteroids—the paper reports no significant genotype-related difference in a cellular sensitivity assay—and our copy does not report osteonecrosis incidence. (LLM, conf=0.82)

  • Responsiveness to anti-VEGF, corticosteroids, and tyrosine kinase inhibitors hinges on BIM function, with BIM polymorphisms negating effective treatment.

    “Responsiveness to anti-VEGF, corticosteroids, and tyrosine kinase inhibitors hinge on BIM function, with BIM polymorphisms negating effective treatment [27, 33, 39].”

    From Thrombospondin-1, BIM and CFH polymorphisms and response to anti-VEGF treatment in neovascular age- related macular degeneration patients (2024) · cites this paper as [39]

    The Discussion (page unavailable) links BIM function and a BIM polymorphism to corticosteroid response in children with ALL, and reports a previously described polymorphism affecting tyrosine kinase inhibitor sensitivity. It does not address anti-VEGF treatment. Its conclusion also describes BIM variation as one component of multifactorial resistance, not as negating effective treatment. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
