科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 基因组学就是基因组学.
背景情况:
- 黑色素瘤微卫星是单独的瘤焦点,假设是淋巴血管转移.
- 它们的分子特征和在疾病进展中的作用仍然未被研究.
研究的目的:
- 为了比较黑色素瘤微卫星中的基因表达与匹配的原发性瘤.
- 确定驱动微卫星形成和进展的分子机制.
主要方法:
- 空间转录学被用来分析微卫星和两个患者的原发性黑色素瘤中的基因表达.
- 用基因组丰富分析和免疫组织化学来验证发现.
主要成果:
- 在微卫星中确定了与血管入侵,循环存活,矩阵重塑和血管生成相关的反复改变的基因.

02:17The Tumor Microenvironment
6.3K
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...

02:30Metastasis
5.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
