概括
在巴基斯坦7.8%的B细胞慢性淋巴细胞白血病 (B-CLL) 患者中发现了TP53突变. 较短的淋巴细胞倍增时间 (LDT) 可能表明TP53突变和侵袭性疾病.
科学领域:
- 血液学 血液学 血液学

- 遗传学 是一个遗传学.
背景情况:
- 在B细胞慢性淋巴细胞白血病 (B-CLL) 中,TP53突变具有重要意义.
- 了解TP53突变频率及其在不同人群中的临床相关性至关重要.
- 淋巴细胞翻倍时间 (LDT) 是疾病进展的潜在指标.
研究的目的:
- 在诊断时确定巴基斯坦B-CLL患者TP53突变的频率.
- 调查LDT<1年是否可以作为B-CLL中TP53突变的替代标记.
主要方法:
- 进行了一项横截面描述性研究.

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...

11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
