概括
在质母细胞瘤中的高斯坦尼奥卡尔-2 (STC2) 表达预测了更短的生存期. STC2是一种独立的预后标志物,建议潜在的治疗点,以改善患者的治疗结果.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 生物标志物研究 生物标志物研究
背景情况:
- 质母细胞瘤 (GBM) 是一种具有不良预后的侵袭性脑瘤.
- 确定可靠的预后标志物对于治疗分层和发展至关重要.
- 斯坦尼奥卡尔-2 (STC2) 是一种在癌症中具有潜在作用的激素,但其在GBM中的预后意义尚未得到充分确立.
研究的目的:
- 为了研究在质母细胞瘤患者中Stanniocalcin-2 (STC2) 表达的预后价值.
- 为了将STC2表达水平与无进展生存率 (PFS) 和整体生存率 (OS) 相关联.
- 检查STC2表达与GBM确定的临床病理特征之间的关系.
主要方法:
- 免疫组织化学被用来评估83名GBM患者的瘤组织中的STC2表达.
- 患者被分为负,低和高STC2表达组.
- 使用卡普兰-梅尔分析和多变量考克斯回归来评估生存结果和独立的预后值.
主要成果:
- 高STC2表达显着与较短的OS (8 vs. 20个月) 和PFS (6 vs. 18个月) 相关.
- 在GBM患者中,STC2表达是OS和PFS的独立预测因子.
- 升高的STC2水平与晚年,较低的ECOG性能状态和IDH野生类型状态相关.
结论:
- 增高的STC2表达作为质母细胞瘤的不良预后标志物.
- STC2可能是一个治疗标,潜在的策略包括途径抑制剂和抗体-药物合物.
- 准STC2可以增强目前的GBM治疗模式,改善患者的生存率.

mTOR 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.

lncRNA - Long Non-coding RNAs
8.5K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
