概括
Myc重组 (Myc-R) 是新诊断的多发性骨髓瘤 (NDMM) 的一个独立的不良预后因素. 将Myc-R或多个高风险细胞遗传异常 (HRCAs) 纳入风险模型可以提高其对患者结果的预测价值.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.

背景情况:
- Myc重组 (Myc-R) 是新诊断的多发性骨髓瘤 (NDMM) 中一个有争议的预后因素.
- 它对患者结果的影响需要进一步澄清.
- 了解Myc-R的作用对于准确的风险分层至关重要.
研究的目的:
- 评估Myc-R在NDMM患者的预后影响.
- 为了比较Myc-R的预测值与传统的高风险细胞遗传异常 (HRCAs).

01:06Induced Pluripotent Stem Cells
4.0K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

02:23Abnormal Proliferation
4.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
