Transcriptional Regulation by the NFAT Family in Acute Myeloid Leukaemia

Acute myeloid leukaemia (AML) is a haematological cancer with poor outcomes due to a lack of efficacious targeted therapies. The Nuclear Factor of Activated T Cells (NFAT) family of transcription factors is well characterised as a regulator of the cell cycle and differentiation in the myeloid lineage. Recent evidence has demonstrated that NFAT family members may have roles in regulating AML leukemogenesis and resistance to targeted therapy in myeloid leukaemia. Furthermore, gene expression data from patient samples show that some NFATs are more highly expressed in poorly differentiated AML and after disease relapse, implying that the NFAT family may have roles in specific types of AML. This review outlines the evidence for the role of NFAT in healthy myeloid tissue and explores how NFAT might regulate AML pathogenesis, highlighting the potential to target specific NFAT proteins therapeutically in AML.

Morphofunctional Adaption of the Renal Tissue of Acipenser Ruthenus (Actinopterygii, Acipenseriformes) under Transformed Habitation Conditions

The morphofunctional state of the mesonephros of the sterlet (Acipenser ruthenus Linnaeus, 1758) from the lower reach of the Dnieper river has been studied through the light optical method. The adaptive changes in the structure-functional elements of the mesonephros nephrons have been observed. Among the most perceivable shift s are focal hemorrhage of the reticulo-myeloid tissue, swelling of the epithelium and inflammatory processes. The abnormalities reported are a response to the negative impact of the wastewater constituents

Thrombotic Thrombocytopenic Purpura and Bone Marrow Necrosis as the Initial Presentation of Lung Cancer

Thrombotic thrombocytopenic purpura (TTP) is a disseminated form of thrombotic microangiopathy. Although most cases are held to be idiopathic, its association with malignancy is well recognized, and it usually occurs at the terminal stage of cancer. Bone marrow necrosis (BMN) is another rare disorder defined pathologically as the necrosis of myeloid tissue and medullary stroma with preservation of bone. Although hematologic malignancy is the most common underlying disease associated with BMN, it can also be caused by solid tumors. The occurrence of TTP with BMN associated with lung cancer has not been reported in the English literature. First described is a patient with the rare association of TTP and BMN displayed as the first manifestations of a lung cancer.
