概括
在前十字带 (ACL) 重建手术后,微RNA (miRNA) 和代谢物概况的早期变化受时间和性别的影响. 这些早期的分子变化可能会影响创伤后关节炎 (PTOA) 的发展.
科学领域:
- 生物化学 生物化学
- 分子生物学分子生物学
- 整形外科 整形外科 整形外科
背景情况:
- 前十字带 (ACL) 重建并不能预防创伤后关节炎 (PTOA).
- 在ACL损伤和重建后,早期循环的microRNA (miRNA) 和代谢物变化还没有得到很好的定义.
- 这些分子变化的性别差异可能会影响PTOA轨迹.
研究的目的:
- 在ACL重建后的早期阶段识别血miRNA和代谢物水平的变化.
- 为了研究女性和男性手术后这些分子形状的差异.
主要方法:
- 分析了从43名ACL重建患者的血在基线,2周和手术后6周.
- 使用高通量miRNA测序和代谢学.
- 用负二项式和线性回归来进行微分表达式分析,用计算生物学来进行路径分析.
主要成果:
- 46个miRNA和13个代谢物增加,而6个代谢物在手术后2周减少,与基线相比.
- 特定的miRNAs (hsa-miR-145-5p,hsa-miR-497-5p,hsa-miR-143-5p) 在不同时间点显示女性比男性的水平更高.
- 五种代谢物 (L-氨酸,g-guanidinobutyrate,肌氨酸,2-methylbutyrylcarnitine,leu-pro) 在2周后在女性相比男性下降.
结论:
- 血miRNA和代谢物概况在早期的ACL重建后期因时间和性别而显著改变.
- 这些早期的分子变化可能在影响手术结果和随后发展PTOA的风险方面发挥作用.

01:22MicroRNAs
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA ends...

01:20Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
