Activation of peroxisome proliferator-activated receptor-γ (PPARγ) inhibits growth of cancer cells including non-small cell lung cancer (NSCLC). Clinically, use of thiazolidinediones, which are pharmacological activators of PPARγ is associated with a lower risk of developing lung cancer. However, the role of this pathway in lung cancer metastasis has not been examined well. The systemic effect ...

Rhabdomyosarcoma frequently infiltrates bone marrow and this process involves the stromal-derived factor-1 (SDF-1)-CXCR4 axis. Because leukemia inhibitory factor (LIF), like SDF-1, is secreted by bone marrow stroma and directs the regeneration of skeletal muscles, we examined whether the LIF-LIF receptor (LIF-R) axis affects the biology of rhabdomyosarcoma cells. We found that in rhabdomyosarco...

Background: Pancytopenia is a manifestation of a wide range of disorders. The main prognostic factor for predicting outcome and response to treatment is based on the underlying cause. To detect the root cause of this problem, depending on other accompanied signs or symptoms, the need for bone marrow examination and other advanced work ups is different at least at the practical level. This study...

Background: Previous studies about the relationship between bone marrow megakaryocyte count and the chronicity of ITP has yielded paradoxical results. The aim of the present study was to investigate any relationship between the megakaryocyte count in the bone marrow and the chronicity of ITP. Materials and Methods: This study was performed to compare the primary bone marrow aspiration megakar...

  Background and Objectives: Bone marrow necrosis (BMN) is a rare and ominous complication of wide variety of diseases including hematologic malignancy. This study was performed to identify frequency and the underlying associated diseases of marrow necrosis. Materials and Methods: In this descriptive study, totally 850 bone marrow trephine biopsies related to living patients at the Pathology ...
