Multidrug resistance-associated protein 1 predicts relapse in Iranian childhood acute lymphoblastic leukemia.

The role of ATP-binding cassette transporter A2 in childhood acute lymphoblastic leukemia multidrug resistance

Acute lymphoblastic leukemia (ALL) is one of the most prevalent hematologic malignancies in children. Although the cure rate of ALL has improved over the past decades, the most important reason for ALL treatment failure is multidrug resistance (MDR) phenomenon. The current study aims to explain the mechanisms involved in multidrug resistance of childhood ALL, and introduces ATP-binding cassette...

Face Bones Involvement and Relapse in a Case of Childhood Acute Leukemia

Midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. Herein, we describe a case of acute pre B cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. At the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. Our case sug...

Evaluation of Relationship between Minimal Residual Disease (MRD) and Relapse in Childhood Acute Lymphoblastic Leukemia (ALL) Using Quantitative Fluorescent PCR

Relationship between major vault protein/lung resistance protein, multidrug resistance-associated protein, P-glycoprotein expression, and drug resistance in childhood leukemia.

Cellular drug resistance is related to a poor prognosis in childhood leukemia, but little is known about the underlying mechanisms. We studied the expression of P-glycoprotein (P-gp), multidrug resistance (MDR)-associated protein (MRP), and major vault protein/lung resistance protein (LRP) in 141 children with acute lymphoblastic leukemia (ALL) and 27 with acute myeloid leukemia (AML) by flow c...

Assocition between LAPTM4B gene polymorphism and the risk of childhood acute lymphoblastic leukemia

Introduction: Evidence suggests that Lysosome associated protein transmembrane 4B (LAPTM4B) contributes to the risk of numerous cancers. The present study aimed to find out the impact of LAPTM4B polymorphism on the risk of childhood acute lymphoblastic leukemia (ALL) in the southeastern Iranian population. Materials and Methods: A total of 230 subjects including 110 children diagnosed with ALL ...
