概括
微转因子家族 (MiTF) 转位细胞癌 (RCC) 是一种罕见且具有攻击性,影响年轻患者. 与其他类型的RCC相比,MiTF RCC的无复发存活率 (RFS) 显著较低,影响了治疗决策.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 微转因子家族 (MiTF) 转位细胞癌 (RCC) 是一种罕见的,具有攻击性的瘤.
- 这些癌症主要影响年轻人,并与预后不佳有关.
研究的目的:
- 分析MiTF RCC的临床和病理特征.
- 为了比较MiTF RCC和常规透明细胞RCC (ccRCC) 之间的无复发生存期 (RFS).
主要方法:
- 在2015年至2023年间对960名经过手术的RCC患者进行了回顾性单心研究.
- 通过免疫组织化学 (IHC) 和光局部杂交 (FISH) 证实了MiTF RCC诊断.
- 用于RFS比较的Kaplan-Meier分析和日志等级测试.
主要成果:

03:03mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

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,...
