摘要
背景：众所周知，微小 RNA 是血小板中信使 RNA 翻译的主要调节因子，在血小板储存过程中的凋亡过程中起着至关重要的作用。我们之前的研究发现，在维持条件下，血小板中 miR-145 和 miR-326 的表达发生了显著变化。本研究旨在评估左旋肉碱（LC）作为添加剂通过改变微RNA的表达来提高血小板质量的效果：我们使用了 10 袋血小板浓缩物（PC），并将每袋分为两等份，分别是经 LC 处理的 PC 和不含 LC 的 PC。使用实时 PCR 测定 miR-145 和 miR-326 的表达。此外，我们还测定了所有样本的血小板计数、血小板聚集、血小板活力和乳酸脱氢酶活性：结果：在血小板储存期间，miR-326 的表达量明显增加，对照组的平均变化倍数为 3.2，经 LC 处理的 PC 的平均变化倍数为 2.5。与 LC 处理的 PC（0.79）相比，对照 PC 中 miR-145 表达的平均折叠变化较小（0.52）。与未处理的 PC 相比，经 LC 处理的 PC 的血小板计数、血小板聚集和血小板活力水平均有所提高：结论：LC 对血小板凋亡有保护作用，可减少凋亡微RNA的表达，并防止抗凋亡微RNA的减少。
L-carnitine contributes to enhancement of viability and quality of platelet concentrates through changing the apoptotic and anti-apoptotic associated microRNAs
Background
Micro RNAs are known as the main regulator of messenger RNA translation in platelets and have a vital role in process of apoptosis during platelet storage. Our pervious study revealed that the expression of miR-145 and miR-326 changed significantly in platelets under maintenance conditions. This study aimed to evaluate the effect of L-carnitine (LC) as an additive to augment platelet quality by changing the microRNA expression.
Methods
We used ten platelet concentrate (PC) bags and divided each into two equal parts, LC- treated, and LC free PC. The expression of miR-145 and miR-326 were determined using real-time PCR. Moreover, we measured platelet count, platelet aggregation, platelet viability, and lactate dehydrogenase activity in all samples.
Results
The miR-326 expression significantly increased during platelet storage with mean fold changes of 3.2 for the control and 2.5 for LC- treated PC. The mean fold changes in miR-145 expression was less in the control PC (0.52) compared to the LC- treated PC (0.79). Increased levels of platelet count, platelet aggregation, and platelet viability were found in the LC-treated compared to the untreated PC.
Conclusion
LC has a protective effect on platelet apoptosis, reduces the expression of apoptotic microRNA, and prevents the reduction of anti-apoptotic microRNA.
