概括
罕见的儿科肌皮细胞癌缺乏可操作的DNA突变,但瘤RNA测序 (RNA-Seq) 确定了治疗点. 对RNA表达的比较分析 (CARE) 框架使得有针对性的治疗成为可能,从而导致持久的临床反应.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 儿科癌症研究儿童癌症研究
背景情况:
- 肌皮细胞癌是一种超罕见的儿科固体瘤,缺乏向治疗选择.
- 瘤RNA测序 (RNA-Seq) 在儿童癌症中识别治疗点的临床实用性仍未得到充分研究.
- "RNA表达的比较分析" (CARE) 框架以前是为了将RNA-Seq数据整合到难以治疗的儿科癌症的临床决策中而开发的.
研究的目的:

Targeted Cancer Therapies
7.4K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Experimental RNAi
6.0K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

MicroRNAs
3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
