背景情况:
- 结肠直肠癌 (CRC) 是癌症死亡的主要原因,结肠直肠腺瘤 (CRA) 是其前体.
- 识别可修改的风险因素,包括维生素D状态和胰岛素样生长因子 (IGF) 轴,对于CRC预防策略至关重要.
研究的目的:
- 研究血清中维生素D代谢物 (胆,,) 和IGF轴组件 (IGF-1,IGFBP-3) 与结直肠腺瘤 (CRA) 风险之间的关联.
主要方法:
- 一项涉及85名参与者 (53名CRA患者,32名对照人) 的病例控制研究,他们接受了结肠镜检查.
- 测量了维生素D3 (胆醇),,,IGF-1和IGFBP-3的血清度,并分析了与CRA状态的关联.
主要成果:
- 较低的血清胆醇水平被确定为CRA的一个显著风险因素 (OR = 4.63,p = 0.004).
- 两组之间没有发现卡尔基或卡尔基醇水平的显著差异,尽管卡尔基缺乏症普遍存在.
- 在CRA患者中,IGF-1水平与年龄,醇和IGFBP-3呈现逆相关性.
结论:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
328
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.1K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
