概括

在子宫光滑肌瘤中,FOXO3a是不受调节的,高水平与转移和leiomyosarcomas的生存率差相关. 这表明FOXO3a可能是这些癌症的治疗点.

科学领域:

妇科瘤学妇科瘤学
分子生物学分子生物学
癌症遗传学癌症遗传学

背景情况:

子宫光滑肌瘤 (USMT) 包括乳腺髓瘤 (LMS) 和乳腺肌瘤 (LM).
了解推动USMT发展和进展的分子机制对于向疗法至关重要.

研究的目的:

调查USMT中FOXO3a的放松管制.
探索FOXO3a表达与癌症发展,转移和预后之间的关联.
在USMT中识别潜在的治疗点.

主要方法:

在LMS,LM和肌肉膜 (MM) 样本中分析FOXO3a的基因和蛋白质表达,使用包括免疫组织化学 (IHC),FISH/CISH和qRT-PCR在内的技术.
在体分析以绘制FOXO3a相互作用网络的地图.
微RNA (miRNA) 分析,以确定调节性miRNAs.

主要成果:

与传统的骨髓瘤 (LM) 和子宫肌瘤 (MM) 相比,FOXO3a基因和蛋白质表达在LMS和不寻常的骨髓瘤 (ULM) 中升高.
在LMS患者中,增加FOXO3a表达与转移和较差的整体存活率 (OS) 有显著的相关性.
在LMS中观察到miR-96-5p和miR-155-5p的上调和miR-let7c-5p的下调,这表明miRNA介导FOXO3a的调节.

结论:

在USMT中FOXO3a放松调节可能是由蛋白质酸化和改变的miRNA活性引起的.

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
