Integrated miRNAome, transcriptome, and degradome analyses reveal the role of miRNA-mRNA modules in the biosynthesis of oridonin in Isodon rubescens.[Pubmed:40606481]
Front Plant Sci. 2025 Jun 18;16:1566354.
INTRODUCTION: Isodon rubescens contains many bioactive diterpenoids, especially oridonin, which are used both as medicines and drinks. However, the structure and content of the diterpenoids in I. rubescens vary greatly in response to different ecological environments. MicroRNAs (miRNAs) play a pivotal role in the biosynthesis of secondary metabolites; but their roles in I. rubescens are obscure. METHODS: This research involved conducting miRNAome, transcriptome, and degradome sequencing analysis of three ecotypes of I. rubescens. Furthermore, the regulation of two candidate miRNA-mRNA modules was validated through a dual-luciferase reporter system. RESULTS: In this study, a total of 1634 miRNAs were identified from 9 miRNAome libraries of three I. rubescens ecotypes, which contained various contents of oridonin, lasiodonin, and Rosthorin A. Furthermore, 99 DEMs and 8180 DEGs were obtained across three I. rubescens ecotypes, and the expressions of selected DEMs and DEGs were verified via reverse transcription quantitative PCR (RT-qPCR). A total of 8928 miRNA-mRNAs networks were identified by degradome analysis, and 23 miRNA-mRNA modules were enriched in the terpenoid biosynthesis pathway. Additionally, 92 negatively correlated DEM‒DEG modules were identified through integrated miRNAome, transcriptome, and degradome analyses, ath-miR858b_1ss21GA‒MYB and ath-miR408-3p_L-1R+1‒CYP72A219 modules were likely involved in oridonin biosynthesis in I. rubescens. Furthermore, the negative regulation of ath-miR858b_1ss21GA targeted MYB was validated through a dual-luciferase reporter system. DISCUSSION: This study revealed that Ath-miR858b_1ss21GA could repress MYB transcription, potentially downregulating the specific genes involved in the biosynthesis of oridonin and reducing oridonin accumulation in I. rubescens.
Rosthorin A inhibits non-small cell lung cancer cell growth and metastasis through repressing epithelial-mesenchymal transition via downregulating Slug.[Pubmed:33065690]
Anticancer Drugs. 2020 Nov;31(10):997-1003.
Lung cancer always ranks first in the number of cancer deaths every year, accounting for 18.4% of total cancer deaths in 2018. Metastasis is the main cause of death in lung cancer patients. The identification of bioactive components of traditional Chinese medicine is very important for the development of novel reagents against non-small cell lung cancer (NSCLC). Rosthorin A has originated from Rabdosia rosthornii (Diels) Hara which excerpts from 'Chinese materia medica', and is known to have 'clear heat phlegm' properties in the folk. Little is known about the biological functions and mechanisms of Rosthorin A in cancer cells at present. The role of EMT in metastasis of a tumor cell is self-evident. Slug is an important EMT inducer, which is related to the development of lung cancer. Cell growth, clone assay, cell migration, cell invasion, and protein expression, and NSCLC transplanted tumor growth were performed in A549, H1299, and H1975 cells. Rosthorin A significantly inhibited the growth of NSCLC cells, it could prolong the survival of nude mice. Rosthorin A inhibited the migration and invasion of A549, H1299, and H1975 cells. Rosthorin A up-regulated E-cadherin expression level and down-regulated the expression of beta-catenin, N-cadherin, vimentin, Slug, and Twist. Rosthorin A could promote the expression of E-cadherin and inhibit the development of EMT by downregulating Slug, to inhibit the development and metastasis of NSCLC cells. In summary, Rosthorin A could be used as a promising candidate for the treatment of NSCLC patients with recurrence and metastasis.
Antiproliferative ent-Kauranoids from Isodon parvifolius.[Pubmed:16732517]
Planta Med. 2006 Jun;72(8):740-5.
Nine new 7alpha,20-epoxy- ENT-kaurane diterpenoids, parvifolines O - W (1 - 9), together with five known analogues, lasiocarpanin (10), Rosthorin A (11), longikaurin E (12), adenolin D (13) and longikaurin B (14), were isolated from the leaves of Isodon parvifolius. Their structures were determined by means of spectroscopic analysis. Selected diterpenoids (1 - 10) were tested for their antiproliferative activity against A549, HT-29 and K562 cells. Compounds 3, 7, 8 and 10 showed moderate inhibitory activity against all three cell lines.
Cytotoxic ent-kauranoids from Isodon leucophyllus.[Pubmed:15008461]
J Asian Nat Prod Res. 2004 Jun;6(2):145-50.
Two new compounds, baiyecrystals D and E (1, 2), together with eight known analogues, xerophilusin B (4), macrocalin B (5), oridonin (6), Rosthorin A (7), lasiocarpanin (8), rabdoternin A (9) and phyllostachysin A (10) and B (11), were isolated from the aerial parts of Isodon leucophyllus. The structures of 1 and 2 and 4-11 were elucidated on the basis of spectroscopic methods, especially the 2D NMR spectral analysis. Compounds 2, 6-8 and 10 were evaluated for their antineoplastic activities in vitro. Among them, lasiocarpanin (8) showed significant inhibitory activities against K562 and Bcap37 cells, with the IC50 values of 0.13 and 1.26 microg mL(-1), respectively, which were lower than those of the positive control.
Cytotoxic 7,20-epoxy ent-kauranoids from Isodon xerophilus.[Pubmed:11524129]
Phytochemistry. 2001 Sep;58(1):179-83.
Four 7,20-epoxy ent-kaurane diterpenoids, xerophilusins G (1) and I-K (2-4), were isolated from the leaves of Isodon xerophilus, along with four known ones, enanderianin C (5), Rosthorin A (6), longikaurin B (7), and rabdoternin D (8). Their structures were determined primarily using NMR spectroscopic techniques. The structure and stereochemistry of 3 were confirmed by X-ray crystallography. Compounds 4 and 7 exhibited broad cytotoxicity against four kinds of human tumor cells (K562, HL-60, HCT, and MKN-28 cells) in the range of 2.23-15.35 and 0.30-8.61 microg/ml, respectively.
