概括
膀皮癌 (UBC) 的OLC1表达升高,与吸烟有关. 这表明,OLC1可能是预测UBC预后的有用生物标志物,特别是在吸烟者中.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
背景情况:
- 膀泌尿腺癌 (UBC) 是一个重大的健康问题.
- 特定基因表达的作用,如OLC1,在UBC的发展和进展需要进一步阐明.
- 吸烟是UBC的已知危险因素之一.
研究的目的:
- 为了研究 OLC1 基因表达在膀泌尿腺癌中的临床意义.
- 确定OLC1表达,吸烟和UBC预后之间的相关性.
主要方法:
- 在UBC样本中分析了OLC1mRNA和蛋白质表达,使用mRNA阵列,反向实时PCR和免疫组织化学染色.
- 使用动物模型研究了暴露于香烟烟雾对OLC1表达的影响.
- 进行了统计分析,以将OLC1表达与瘤阶段,吸烟史和无疾病生存率相关联.
主要成果:
- 与正常组织相比,ULC1的mRNA和蛋白质表达在UBC瘤样本中明显高.
- 升高的OLC1表达与晚期瘤相相关,在吸烟者中显著高,特别是那些吸烟强度较高的人.
- 在UBC患者中,OLC1蛋白表达和吸烟史与较差的无疾病生存率有关.
- 在小鼠中,暴露于香烟烟雾导致膀 uroepithelium 中的 OLC1 mRNA 表达增加.
结论:
- 在膀泌尿道癌中,OLC1的升高调节.
- OLC1的表达受到吸烟的影响.
- OLC1显示出作为UBC预后生物标志物的潜力,特别是在吸烟史的背景下.

02:39lncRNA - Long Non-coding RNAs
8.6K
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...

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,...
