Project description:Purpose: Next-generation sequencing (NGS) was performed to illustrate the genetic molecular mechanism underlying varicocele (VC) pathogenesis and Morinda officinalis polysaccharide (MOP) repair effect. Methods: The male Sprague–Dawley (SD) rats (about 6-7 weeks old and 200±10g weight) were divided into three groups: 1) control group (Control); 2) experimental varicocele group (VC); 3) 300 mg kg-1 MOP administration group (VC+MOP). The next-generation RNA sequencing were performed to identify the differentially-expressed mRNA and lncRNA in left testicular tissue between each two compared group. Results: The result show that a total of 144 mRNAs and 63 LncRNAs, 63 mRNAs and 148 LncRNAs , 173 mRNAs and 54 LncRNAs were found differentially expressed between compared group VC vs. Control, VC+MOP vs. VC, and VC+MOP vs. Control respectively. Conclusions: Our study try to offer a indication for novel diagnose marker and therapeutic method, as well as provide feasible research orientations for further study.
Project description:Cornus officinalis Sieb. et Zucc., a perennial woody plant which is recognized with high medicinal, economic and ecological values, has been used as traditional Chinese medicine (TCM) for thousands of years in China. Modern pharmacological research has revealed that cornel iridoid glycosides (CIGs, e.g. loganin and morroniside) in dried pericarp of C. officinalis have significant medicinal activities for strengthening immune functions. However, little is known on the molecular processes responsible for the medical properties of this species, owing to the absence of genomic resources such as available sequences of key enzyme genes in biosynthetic pathways. In this study, the RNA sequencing data of C. officinalis were first generated and used for transcriptome analysis. A total of 54,827 unigenes with an average length of 817 bp, an N50 of 1,379 bp, and an average GC content of 44.91% were yielded by de novo assembly, of which 31,780 unigenes were successfully annotated. As potential molecular markers, 121, 118, 96, 89, and 82 transcription factors belonged to bHLH, MYB, PHD, WRKY, and AP2-ERF were further analyzed, respectively. The results of qRT-PCR confirmed that geraniol 10-hydroxylase (G10H) and loganin synthase (SLS) were differentially expressed in fruits and leaves during different growing stages. Furthermore, we found that loganin accumulation was positively related to G10H expression but was negatively correlated with SLS expression. Collectively, the genomic information and gene expression results presented in this study will be helpful for future studies on gene discovery and molecular process of loganin synthesis in C. officinalis.
