An overview of the molecular and clinical significance of the angiopoietin system in leukemia.

The angiogenesis efficacy in solid tumors and hematological malignancies has been identified for more than twenty years. Although the exact role of angiogenesis in leukemia as a common hematological malignancy has not yet been extensively studied, its effect is demonstrated on the initiation and maintenance of a favorable microenvironment for leukemia cell proliferation. The angiopoietin family is a defined molecular mediator for angiogenesis, which contributes to vascular permeability and angiogenesis initiation.

Comparison of High-Resolution Melting (HRM) Analysis with Direct Sequencing for the Detection of DNMT3A Mutations in AML Patients.

Objective: Acute myeloid leukemia (AML) is caused by abnormal gene expression following mutations. Many of the mutations in AML lead to gene instability and poor response to treatment. Among these mutations, DNMT3A mutation is exceedingly important due to its major role in methylation and its effect on the expression of other genes.

Rapid Detection of N-RAS Gene Common Mutations in Acute Myeloid Leukemia (AML) Using High Resolution Melting (HRM) Method.

Objective: Acute myeloid leukemia is caused by the clonal proliferation of undifferentiated myeloid hematopoietic precursors. AML prognosis is highly involved in the treatment response and is determined by mutations in several genes such as N-RAS. This study aims to identify the distribution of common N-RAS mutations (codons 12, 13, and 61) in AML patients using the HRM method and confirm this method's efficiency for mutation detection by comparing its results with the sequencing data as the Gold standard method.

Investigating the expression pattern of the angiopoietin-Tie system in ALL and its correlation with baseline characteristics.

Background: Acute lymphoblastic leukemia (ALL) is the most common type of leukemia in children. Several environmental and genetic factors are known to be involved in its development and progression. The angiopoietin-Tie system is one of the most critical factors in angiogenesis, and its possible role in solid tumors and leukemia has been previously investigated.

IGF family effects on development, stability, and treatment of hematological malignancies.

Multiple factors, including growth factors, are shown to be culprits of cancer outset and persistence. Among growth factors, insulin-like growth factors (IGFs) family are of more importance in the prognosis of blood malignancies. After binding to their corresponding receptor, IGFs initiate PI3K/AKT signaling pathway and increase the translation of intracellular proteins, such as cell division-related proteins.
