Abstract

To analyze the promoter methylation status, mRNA expression and clinical significance of DKK-3 and WIF-1 genes in patients with acute myeloid leukemia(AML). Methylation specific polymerase chain reaction (MS-PCR) mothod was carried out to detect DKK-3 and WIF-1 gene promoter methylation status in bone marrow specimen from 56 patients with AML and 20 patients with iron deficiency anaemia(IDA) as control; then the real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to detect mRNA expression of DKK-3, WIF-1 gene and β -catenin in the above-mentioned specinens, and their relationship with the clinical features and survival time was analyzed. The promoter methylation rate of DKK-3 and WIF-1 gene in AML patients were significantly higher than that in control group(χ2=15.330,P<0.001; χ2=17.371,P<0.001). There was no relationship between DKK-3 and WIF-1 gene promoter methylation rate and AML patient's sex, age, clinical typing. The relative expression of DKK-3 and WIF-1 gene mRNA in AML group were 0.840±0.320 and 0.792±0.313, which were lower than those in control group (1.134±0.392 and 1.047±0.334) respectively, the difference was statistically significant (t=3.415,P=0.000; t=3.070, P=0.003).

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.

AML: Role of LSD1 by CRISPR (Keystone)

Find the latest rersearrch on the ability of CRISPR-Cas9 mutagenesis to profile the interactions between lysine-specific histone demethylase 1 (LSD1) and chemical inhibitors in the context of acute myeloid leukemia (AML) here.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins. Discover the latest research on cadherins and catenins here.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
