Identification of de Novo Fanconi Anemia in Younger Patients With Newly Diagnosed Acute Myeloid Leukemia

2014-08-27 03:12:49 | BioPortfolio

Summary

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to Fanconi anemia in patients with acute myeloid leukemia.

PURPOSE: This research study is studying identification of de novo Fanconi anemia in younger patients with newly diagnosed acute myeloid leukemia.

Description

OBJECTIVES:

- Identify children with newly diagnosed acute myeloid leukemia (AML) treated on COG-2961 and COG-AAML03P1 who are at high risk of having de novo Fanconi anemia.

- Procure diagnostic samples from the COG AML Biology Repository and identify Fanconi anemia patients using western blot techniques.

OUTLINE: Previously collected cryopreserved cells are analyzed via western blot to identify patients with Fanconi anemia.

Medical and Biotech [MESH] Definitions

A method that is used to detect DNA-protein interactions. Proteins are separated by electrophoresis and blotted onto a nitrocellulose membrane similar to Western blotting (BLOTTING, WESTERN) but the proteins are identified when they bind labeled DNA PROBES (as with Southern blotting (BLOTTING, SOUTHERN)) instead of antibodies.

A method that is derived from western blotting (BLOTTING, WESTERN) and is used to detect protein-protein interactions. The blotted proteins are probed with a non-antibody protein which can then be tagged with a labeled antibody.

A Fanconi anemia complementation group protein that undergoes PHOSPHORYLATION by CDC2 PROTEIN KINASE during MITOSIS. It forms a complex with other FANCONI ANEMIA PROTEINS and helps protect CELLS from DNA DAMAGE by genotoxic agents.

A Fanconi anemia complementation group protein that is the most commonly mutated protein in FANCONI ANEMIA. It undergoes PHOSPHORYLATION by PROTEIN KINASE B and forms a complex with FANCC PROTEIN in the CELL NUCLEUS.

A Fanconi anemia complementation group protein that contains an N-terminal DNA-binding region and seven, C-terminal, WD REPEATS. It is an essential factor in HOMOLOGOUS RECOMBINATION DNA REPAIR through its interactions with BRCA2 PROTEIN; RAD51 RECOMBINASE; and BRCA1 PROTEIN. It functions as a molecular scaffold to localize and stabilize these proteins at homologous recombination sites. Mutations in the PALB2 gene are associated with FANCONI ANEMIA complementation group N; type 3 PANCREATIC NEOPLASMS; and susceptibility to BREAST CANCER.
