چکیده مقاله:

Background:Alpha-synuclein is a member of synuclein family of proteins with unidentified function localized in the cytoplasm, mitochondria of neurons, and presynaptic nerve endings. Although it is found in the Lewy bodies in synucleinopathies and in Alzheimer’s disease, the protein could also be considered as a novel marker in diagnosis of diseases related to the hematopoietic system. Methods: The current study evaluated alpha-synuclein expression in bone marrow sections obtained from 9 patients with acute myeloblastic leukemia (AML)-M6, 2 patients with AML-M7, and 56 patients with other forms of AML by immunohistochemical (IHC) analysis Results: Seven out of 9 cases with erythroleukemia (66.7%) and 1 of the 2 cases with M7 (50%) were positive. In contrast; the blasts in 2 out of 56 AML cases with non-M6/M7 (3.6%) showed positive staining. Accordingly, alpha-synuclein was positive in normal erythroid precursors and megakaryocytes (if existing) in these cases; while, it was negative in lymphoid and myeloid precursors. Conclusion: Alpha-synuclein expression in non-neoplastic and neoplastic erythroid cells and megakaryocytes could be used as a complementary and useful marker for distinction between AML-M6/M7 and other types of AML

Alterations of adiponectin gene expression in bone marrow of acute myeloid leukemia

Background: Acute myeloid leukemia (AML) is characterized by the proliferation of myeloid precursors and abnormal differentiation of hematopoietic stem cells, which results in the accumulation of immature cells in the bone marrow (BM). The accumulation of these cells in the bone marrow causes molecular and cellular changes in the microenvironment of the bone marrow. The adiponectin hormone orig...

A man with acute myelogenous leukemia, treated with chemotherapy, had a decrease in circulating formed blood elements. Bone marrow biopsy revealed necrosis. Imaging with In-Ill chloride demonstrated activity in the liver, but not in the spleen or bone marrow. Eighteen days later, the circulating blood count had risen; a repeat bone marrow biopsy showed the return of blood cell precursors....
