概括

端粒酶逆转录酶 (TERT) 促进子突变在年轻的膀癌患者中不太常见. 虽然观察到较差无复发生存率的趋势,但需要进一步的研究.

科学领域:

在瘤学瘤学.
遗传学是一个遗传学.
泌尿器科泌尿器科泌尿器科泌尿器科

背景情况:

TERT基因促进基因突变是尿道膀瘤中经常发生的事件,与瘤进展有关.
了解年轻患者的TERT促进子突变对于了解致癌症至关重要.

研究的目的:

调查40岁或更年轻患者诊断出的尿路膀瘤中TERT促进子突变 (C228T和C250T) 的患病率.
分析TERT促进子突变与瘤特征,无复发生存率 (RFS) 和无进展生存率 (PFS) 之间的关联.

主要方法:

分子分析以检测TERT促进器区域中的C228T和C250T突变.
对29名患者的回顾性研究,平均随访时间为152个月.
具有和没有TERT促进子突变的患者之间的临床和病理特征,RFS和PFS的比较.

主要成果:

根据TERT促进子突变的存在或不存在,在临床或瘤特征中没有发现显著差异.
患有TERT促进子突变的患者表现出较差RFS的趋势,但这没有达到统计学意义.
在突变和非突变组之间没有观察到PFS的显著差异.

结论:

与老年人相比,患有膀瘤的年轻患者的TERT促进子突变发生的频率较低,这表明潜在的不同致癌途径.
在具有突变TERT的年轻患者中观察到较低RFS的趋势,需要在更大的队列中进行进一步的研究,因为这种人群中膀癌的发病率较低.

Replicative Cell Senescence

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Loss of Tumor Suppressor Gene Functions

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Telomeres and Telomerase

Telomeres and Telomerase

In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...
