概括
这项研究确定了关键的长非编码RNAs (lncRNAs) 和信使RNAs (mRNAs) 在受损的骨关节炎软骨中. 这些分子可以作为潜在的生物标志物或治疗关节炎治疗的治疗标.
科学领域:
- 分子生物学分子生物学
- 基因组学就是基因组学.
- 生物信息学是一种生物信息学.
背景情况:
- 骨关节炎 (OA) 是一种退行性关节疾病,其特点是软骨分解.
- 识别OA病变的分子参与者对于开发有效的治疗方法至关重要.
研究的目的:
- 从人类OA患者中识别受损软骨 (DC) 与未受损软骨 (UDC) 中差异表达的长非编码RNA (lncRNA) 和信使RNA (mRNA).
- 通过生物信息学和ceRNA网络建设,探索这些差异表达RNA在OA进展中的作用.
主要方法:
- 来自5名OA患者的软骨样本的RNA测序.
- 基因本体学 (GO) 和基因和基因组的京都百科全书 (KEGG) 路径丰富分析.
- 使用qRT-PCR构建ceRNA网络并验证差异表达RNA.
主要成果:
- 与UDC相比,DC中的5个lncRNA和8个mRNA的显著差异表达.
- 通过qRT-PCR验证关键的lncRNAs (LINC01411,AL596087.2,PCDH20,LRFN2,AL583785.1) 进行验证.
- 确定关键通路 (Ras,PI3K-Akt,MAPK) 和小RNA相互作用,参与OA的发病.
结论:
- 不同表达的lncRNAs和mRNAs涉及到OA软骨内的关键信号通路.
- 这些已识别的RNA具有作为诊断生物标志物或骨关节炎治疗点的潜力.

02:55The Nucleolus
8.6K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

12.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
