概括
乳腺癌手术后的二次淋巴 (LE) 会导致脂肪组织的持久变化. 这项研究揭示了与肥胖引起的脂肪相比,LE脂肪组织中明显的分子特征,为未来的治疗提供了洞察力.
科学领域:
- 在瘤学瘤学.
- 代谢学 代谢学 代谢学
- 利皮多米克 (Lipidomics) 是一种消化剂.
- 基因组学就是基因组学.
背景情况:
- 二次性淋巴 (LE) 是乳腺癌手术后的一种慢性并发症,没有治愈的方法.
- 低脂导致显著的区域脂肪组织积累,往往需要抽脂.
- 了解LE诱导脂肪组织的分子基础对于开发有效的治疗方法至关重要.
研究的目的:
- 描述二次LE患者脂肪组织的转录,新陈代谢和脂质学特征.
- 为了比较LE诱导的脂肪组织与肥胖诱导的脂肪组织的转录组景观.
- 确定LE患者受影响和未受影响脂肪组织之间的分子差异和相似之处.
主要方法:
- 20名女性乳腺癌患者的脂肪组织活检LE (受影响和未受影响的手臂).
- RNA测序,代谢学和脂质学分析.
- 生物信息学和差异基因表达分析比较LE和非LE脂肪组织,以及与瘦/肥胖群体.
主要成果:
- LE脂肪组织显示上调的炎症,化疗和血管生成,下调的表皮分化和神经生成.
- 导致LE的脂肪组织和导致肥胖的脂肪组织的转录形状在很大程度上是不同的.
- 在LE脂肪组织中观察到降低的氨酸水平和SLC6A15载体mRNA;脂管学显示,两臂之间没有显著差异.
结论:
- 乳腺癌手术后的二次LE诱导脂肪组织独特的分子变化,其特征是持续的炎症.
- 与肥胖诱导的脂肪组织相比,LE诱导的脂肪组织表现出明显的转录基因特征.
- 这些发现提供了LE脂肪组织的详细分子特征,突出了与与肥胖相关的脂肪积累的差异.

The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
The Mammary Glands
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
