Fluorinated 2-(4-amino-3-methylphenyl)benzothiazoles possess potent antiproliferative activity against certain cancer cells, similar to the unfluorinated 2-(4-amino-3-methylphenyl)benzothiazole (DF 203, NSC 674495). In "sensitive" cancer cells, DF 203 is metabolized by, can induce expression of, and binds covalently to CYP1A1. Metabolism appears to be essential for its antiproliferative activit...
Liver resection is still the most commonly used therapeutic treatment for hepatocellular carcinoma (HCC), and liver regeneration promotes HCC growth in the regenerating liver. The high recurrence/metastasis of HCC is the main cause of death for HCC patients after liver resection. However, how the augmented growth and metastasis of residual HCC induced by the promoted liver regeneration followin...
A boy with no previous history of bleeding presented with ecchymoses and splenomegaly. He was followed up for thrombocytopenia and micromegakaryocytes for 20 months till clinically malignancy was diagnosed. Micromegakaryocytes must always be treated with suspicion, as they may provide an important clue for dyshematopoesis.
The mammalian genome contains several hundred microRNAs that regulate gene expression through modulation of target mRNAs. Here, we report a fragile chromosomal region lost in specific hematopoietic malignancies. This 7 Mb region encodes about 12% of all genomic microRNAs, including miR-203. This microRNA is additionally hypermethylated in several hematopoietic tumors, including chronic myelogen...
In cancer cells, the mammalian target of rapamycin complex 1 (mTORC1) that requires hormonal and nutrient signals for its activation, is constitutively activated. We found that overexpression of pyruvate kinase M2 (PKM2) activates mTORC1 signaling through phosphorylating mTORC1 inhibitor AKT1 substrate 1 (AKT1S1). An unbiased quantitative phosphoproteomic survey identified 974 PKM2 substrates, ...
پژوهش درمورد غلظت عناصر فلزی در آبزیان از جهت سلامت انسانی اهمیت دارد. هدف از انجام این مطالعه، بررسی میزان غلظت عناصر فلزی روی (Zn)، نیکل (Ni)، قلع (Sn)، آلومینیوم (Al)، وانادیوم (V) و تالیوم (Tl) در بافت خوراکی (عضله) و بافت‌‌های غیر خوراکی (کبد و آبشش) ماهی کفال طلایی و ارتباط آن با جنسیت و شاخص وزن و طول است. نمونه‌‌برداری از ماهی کفال طلایی بالغ، از مناطق مختلف نوار ساحلی دریای خزر در د...
