- 遗传学 是一个遗传学.
背景情况:
- 富含糖原的乳腺癌 (GRC) 是一种罕见的亚型,具有描述的临床病理特征.
- 之前的研究缺乏对GRC的详细遗传分析.
研究的目的:
- 为了调查GRC的遗传景观.
- 在GRC.内识别潜在的分子子组.

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Adaptive Mechanisms in Cancer Cells
7.3K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
