Abstract
Context: Plant microRNAs (miRNAs) present in Yishen Tongluo formula (YSTL, a traditional Chinese herbal medicine formula) are considered as potential therapeutic drugs for reducing the sperm DNA fragmentation index (DFI).
Objective: To study the effectiveness of plant miRNAs in YSTL for repairing mouse sperm DNA damage caused by benzo(a)pyrene (BaP).
Methods and materials: Twenty-four male SPF ICR (CD1) mice were divided into control, BaP and YSTL groups. A BaP-induced (100 mg/kg) sperm DNA damage model was established in the BaP and YSTL groups, and the mice in the YSTL group were treated with YSTL (23.78 g/kg) for 8 weeks. Sperm DFI was determined via a sperm chromatin structure assay (SCSA). MicroRNAs in the testes of the mice were analysed via RNA-seq, and the top four plant miRNAs were screened, identified and overexpressed in GC cells. The effects of plant miRNAs on the viability and DNA integrity of GC cells exposed to benzo(a)pyrene diol epoxide (BPDE) (1 μM) were tested using CCK8 and comet assays.
Results: Compared with that of the BaP group, the DFI of the YSTL group decreased (9.57% vs. 18.54%, F = 18.645, p = 0.0236). miR166-y, miR894-x, miR822-x and miR396-x were screened. The CCK8 and comet assays revealed that the DFI of the mimic group was significantly lower than that of the BPDE (IC50 = 1.006 μM) group, with the most significant difference in the miR396-x group.
Discussion and conclusions: Plant miRNAs such as miR396-x can penetrate the blood-testis barrier through the digestive system to repair sperm DNA.
期刊介绍:
Pharmaceutical Biology will publish manuscripts describing the discovery, methods for discovery, description, analysis characterization, and production/isolation (including sources and surveys) of biologically-active chemicals or other substances, drugs, pharmaceutical products, or preparations utilized in systems of traditional medicine.
Topics may generally encompass any facet of natural product research related to pharmaceutical biology. Papers dealing with agents or topics related to natural product drugs are also appropriate (e.g., semi-synthetic derivatives). Manuscripts will be published as reviews, perspectives, regular research articles, and short communications. The primary criteria for acceptance and publication are scientific rigor and potential to advance the field.
