概括
尼古丁胺N-甲基转移酶 (NNMT) 在子宫乳腺髓瘤 (uLMS) 中过度表达,使其与良性子宫乳腺髓瘤 (uLM) 区别开来. 较高的NNMT水平与先进的LUMS相关,并预测出更糟糕的预后.
科学领域:
- 在瘤学瘤学.
- 分子病理学分子病理学
- 妇科瘤学 妇科瘤学
背景情况:
- 子宫乳腺髓瘤 (uLMS) 是一种罕见的,具有未知起源的侵袭性瘤.
- 从临床上来说,区分LMS和良性子宫乳腺瘤 (uLM) 是非常重要的.
- 尼古丁胺N-甲基转移酶 (NNMT) 涉及各种癌症,但未在子宫介质瘤中进行研究.
研究的目的:
- 调查LUMS,ULM和良性肌肉膜中的NNMT表达.
- 在LMS中将NNMT表达与临床病理特征和预后相关联.
主要方法:
- 免疫组织化学被用来评估NNMT的表达.
- 分析的组织包括31个LMS,7个uLM和31个良性肌肉样本.
- 统计分析将NNMT水平与疾病阶段和存活率相关联.
主要成果:
- 与uLM和肌体相比,LULMS中的NNMT表达显著更高 (p < 0.001).
- 在高级阶段的LMS中观察到NNMT表达的增加 (p = 0.034).
- 在LULMS中,NNMT表达是无复发生存的独立预测因子 (p = 0.037).
结论:
- NNMT可能有助于在手术前区分ULMS和ULM.
- NNMT的过度表达机制与导致中瘤预后不佳的途径保持一致.
- 作为中介细胞恶性瘤的治疗点,NNMT值得进一步研究.

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...

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...
