Systematic Analysis of tRNA-Derived Small RNAs Reveals Novel Potential Therapeutic Targets of Traditional Chinese Medicine (Buyang-Huanwu-Decoction) on Intracerebral Hemorrhage.

ABSTRACT: Although Buyang-Huanwu-Decoction (BYHWD), a famous traditional Chinese medicine, has been utilized to promote the recovery of neurological function in intracerebral hemorrhage (ICH) for centuries, its therapeutic mechanisms remain unclear. tRNA-derived small RNA (tsRNA) is a novel class of short non-coding RNA, possessing potential regulating functions. In the current study, we explored the novel therapeutic targets of BYHWD by tsRNA-sequencing. Rats were randomly divided into three groups: sham, ICH, and BYHWD-treated groups. The modified neurological severity score, corner turn test, foot-fault test, and weight change were used to assess neurological injury. After BYHWD treatment, these behavioral tests were obviously meliorated compared with ICH group in the recovery phase. In the rat brain tissues surrounding the hemorrhagic region, a total of 350 tsRNAs for exact match were identified. 12 of tRNAs (fold change >1.3 and P-value <0.05) were significantly changed in ICH group compared to sham group. Among them, 3 of tRNAs (rno-tRFi-Ser-25a, rno-tRF5-Ala-16a and rno-tRF5-Glu-29a) were markedly regulated by BYHWD treatment and validated with quantitative real-time PCR. Additionally, target prediction and bioinformatics analyses revealed that these tsRNAs could play therapeutic roles through FoxO signaling pathway, positive regulation of long term synaptic depression, autophagy - animal, IL-17 signaling pathway and regulation of cytoskeleton and transforming growth factor beta. In conclusion, tsRNAs are the potential therapeutic targets of BYHWD on ICH treatment. The present study provides novel insights for future investigations to explore the mechanisms, by which BYHWD promotes neurological function recovery after ICH.

Project description:BackgroundHypertension has become a part of the lives of many people worldwide. With the development, an increasing number of people have begun to control their hypertension through products of medicine food homology, such as Buyang Huanwu Decoction (BYHWD). However, there has been no objective review of the regulation of hypertension by BYHWD.MethodsAs of 9 October 2023, this review made a detailed search of nine databases to look for random controlled trials (RCTs) focused on the use of BYHWD for treating hypertension. This was followed by network pharmacological analysis, and molecular docking assessment using AutoDockTools to explore the mode of action.ResultsBYHWD was effective in reducing SBP (MD: 0.767; 95 % CI: 0.629, 0.905; p = 0.000), DBP (MD: 0.427; 95 % CI: 0.292, 0.561; p = 0.000), 24h SBP (MD: 0.665; 95 % CI: 0.368, 0.962; p = 0.000), 24h DBP (MD: 0.547; 95 % CI: 0.318, 0.777; p = 0.000), dSBP (MD: 0.625; 95 % CI: 0.395, 0.855; p = 0.000), dDBP (MD: 0.632; 95 % CI: 0.401, 0.862; p = 0.000), nSBP (MD: 0.859; 95 % CI: 0.340, 1.377; p = 0.001), nDBP (MD: 0.704; 95 % CI: 0.297, 1.112; p = 0.001), pv (MD: 1.311; 95 % CI: 0.363, 2.259; p = 0.007) and NIHSS (MD: 1.149; 95 % CI: 0.100, 2.199; p = 0.032), and elevating CER (OR = 2.848; 95 % CI: 1.388, 5.843; p = 0.004). However, BYHWD did not significantly reduce HCY, and there was no significant difference in the incidence of AE. In terms of the mechanism of action, the main active ingredient of BYHWD is quercetin, and the core targets are AKT1, MMP9, and others. Molecular docking also showed that quercetin mainly interacts with the amino acid residue CYS-28 of MMP2. Second, the KEGG analysis showed that BYHWD mainly act on HIF-1, Apelin, and cGMP-PKG signalling pathways, and GO analysis showed that it related to the apical part of the cell, circulatory system processes, and nuclear receptor activity. Conclusion: BYHWD can lowered blood pressure, reduced plasma viscosity, and restored neurological function with good tolerability, and had no significant effect on HCY levels. This study further demonstrated that quercetin is the main active ingredient of BYHWD that acts via the AKT1 and HIF-1 signalling pathways. These results provide new guidance for people's dietary choices by the general public.
