Abstract
Apocynum venetum L. is an economically valuable plant with tolerance to drought and salinity. Its leaves are utilized in tea production and pharmaceuticals, while the stem bark serves as a high-quality fiber material. To gain insights into the gene expression patterns of A. venetum using quantitative real-time PCR (qRT-PCR), it is crucial to identify appropriate reference genes. This study selected nine candidate genes, including α-tubulin (TUA), β-tubulin (TUB), actin (ACT), cyclophilin (CYP), elongation factor-1α (EF-1α), the B family of regulatory subunits of protein phosphatase (PPP2R2, PPP2R3, and PPP2R5), and phosphoglycerate kinase (PGK), to determine the most appropriate reference genes in the leaf, stem, and root tissues of A. venetum. A comprehensive ranking by geNorm, NormFinder, BestKeeper, and RefFinder software and Venn diagrams was used to screen more stable reference genes in different tissues. The two most stable reference genes were CYP and TUA in leaves, PGK and PPP2R3 in stems, and TUA and EF-1α in roots, respectively. The relative expression values of the four genes involved in proline metabolism under polyethylene glycol treatment were used to validate the screened reference genes, and they exhibited highly stable expression levels. These findings represent the first set of stable reference genes for future gene expression studies in A. venetum. They significantly contribute to enhancing the accuracy and reliability of gene expression analyses in this economically important plant species.

Int J Biol Macromol 2022; 215:23-35. [PMID: 35718143 DOI: 10.1016/j.ijbiomac.2022.06.104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 05/31/2022] [Accepted: 06/12/2022] [Indexed: 11/05/2022]
Abstract
For Codonopsis Radix polysaccharides (CRPs), oral administration is generally considered the most convenient route for patients. However, the details of its absorption and transport mechanisms remain unclear. In this study, we aimed to evaluate the oral absorption of CPA (an inulin-type fructan extracted from CRPs) in mice and Caco-2 cells. It was labeled with fluorescein isothiocyanate, and the fluorescence derivative (FCPA) was used to trace the behavior of CPA. The results showed that FCPA could be absorbed after oral administration and has a wide tissue distribution, including in the stomach, intestine, kidneys, and liver. FCPA was poorly absorbed, and its internalization was time- and energy-dependent, as well as dependent on cholesterol- and dynamin-mediated endocytosis. Confocal laser scanning microscopy showed successful cellular internalization of FCPA from the cytoplasm to the nucleus. In addition, we found that FCPA was trafficked to endosomes and lysosomes, and that tubulin was required for its intracellular transport. These findings add new details to our knowledge of the internalization and transport mechanisms of CPA, which may prove useful to the development and application of oral formulations of CRPs.

Abstract
Codonopsis pilosula (Franch.) Nannf., as a well-known homology plant of medicine and food, has the function of replenishing the Qi, strengthening the spleen and tonifying the lung, nourishing the blood and engendering the liquid in traditional Chinese medicine. Accumulating evidence has demonstrated that the C. pilosula polysaccharides (CPPs) are one of the major and representative pharmacologically active macromolecules and present multiple biological activities both in vitro and in vivo methods, such as immunomodulatory, antitumor, antioxidant, neuroprotective, antiviral, anti-inflammatory, anti-fatigue, hypoglycemic, anti-hypoxia, renoprotective, gastroprotective, hepatoprotective, and prebiotic. The purpose of the present review is to provide comprehensively and systematically reorganized information in the extraction and purification, structure characterization, biological activities and the underlying mechanisms of action as well as toxicities of CPPs to support their therapeutic potentials and sanitarian functions. New valuable insights for the future researches regarding CPPs were also proposed in the fields of therapeutic agents and functional foods.

Response of Bioactive Metabolite and Biosynthesis Related Genes to Methyl Jasmonate Elicitation in Codonopsis pilosula. Molecules 2019; 24:molecules24030533. [PMID: 30717158 PMCID: PMC6385095 DOI: 10.3390/molecules24030533] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 01/24/2019] [Accepted: 01/28/2019] [Indexed: 02/06/2023] Open
Abstract
Bioactive metabolites in Codonopsis pilosula are of particular interest as an immunostimulant. Methyl jasmonate (MeJA) plays an important role in the elicitation of metabolite biosynthesis. Here, we explored the response of metabolites to MeJA elicitation in C. pilosula adventitious roots and multiple shoots. The results showed that the biomass, polysaccharide, and lobetyolin content of adventitious roots exhibited the highest increases with 100 µmol·L−1 MeJA at the 16th day of subculture, whereas the atractylenolide III (a terpenoid) content increased extremely with 50 µmol·L−1 MeJA treatment at the 7th day of subculture. In addition, the biomass and lobetyolin content significantly increased at the 4th day after treatment. Similarly, the polysaccharide and lobetyolin content increased in multiple shoots. Further identification of different metabolites responding to MeJA by 1H-NMR showed an extremely significant increase of the lobetyolinin level, which coincided with lobetyolin. Accordingly, the precursor, fatty acids, showed a highly significant decrease in their levels. Furthermore, a significant increase in β-d-fructose-butanol glycoside was detected, which was accompanied by a decrease in the sucrose level. Accordingly, the enzyme genes responsible for terpenoid and carbohydrate biosynthesis, CpUGPase, and CpPMK, were up regulated. In conclusion, MeJA promoted culture growth and accelerated bioactive metabolite accumulation by regulating the expression of the metabolite biosynthesis related genes, CpUGPase and CpPMK in C. pilosula.
