TwKO is the first CYP450 enzyme involved in the biosynthesis of tripterifordin and neotripterifordin. This study aimed to enhance the catalytic activity of TwKO by site-directed mutagenesis to benefit the production of tripterifordin and neotripterifordin in yeast. The AlphaFold DB established based on the AlphaFold 2 was employed to obtain the protein model of TwKO. According to multiple sequence alignments and principles of natural evolution, the key residues influencing the binding of TwKO to the substrate were identified. Subsequently, functional characterization of the mutants were conducted in Saccharomyces cerevisiae. A total of 71 mutants were obtained, among which 11 and 11 mutants had the abilities of enhancing the production of 16α-hydroxy-ent-kaurenol and 16α-hydroxy-ent-kaurenoic acid, respectively. In addition, 10 mutants could increase the proportion of the oxidation product of 16α-hydroxy-ent-kaurenol. In particular, R304 was identified as a key residue affecting the catalytic specificity of TwKO, the mutation of which led to the specific prodiction of 16α-hydroxy-ent-kaurenol.

The HepG2 cell model of dexamethasone-induced IR(IR-HepG2) was established and treated with 5, 10, and 20 μmol·L~(-1) berberine, respectively, for 24 h. The glucose oxidase method and cell counting kit-8(CCK-8) assay were employed to measure extracellular glucose concentration and cell viability, respectively. Periodic acid-Schiff(PAS) staining and lipid fluorescence method were used to detect glycogen and lipids. The immunofluorescence(IF) assay was employed to detect the nuclear localization of BMAL1 and circadian locomotor output cycles kaput(CLOCK) in IR-HepG2 cells. Western blot was employed to determine the protein levels of BMAL1, CLOCK, period circadian clock 2(PER2), cryptochrome circadian regulator 1(CRY1), Rev-Erbα, carbohydrate response element-binding protein(ChREBP), peroxisome proliferator-activated receptors alpha and gamma(PPARα/γ), sterol regulatory element-binding protein 1C(SREBP-1C), mammalian target of rapamycin(mTOR), protein kinase B(Akt), glycogen synthase kinase-3β(GSK3β), acetyl coenzyme A carboxylase 1(ACC1), fatty acid synthase(FASN), carnitine palmitoyltransferase 1α(CPT1α), nicotinamide phosphoribosyltransferase(NAMPT), silent information regulator 1(SIRT1), adiponectin(ADPN), insulin receptor substrate 2(IRS2), and phosphatidylinositol 3-kinase regulatory subunit p85(PI3Kp85). In addition, the levels of phosphorylated adenosine monophosphate-activated protein kinase alpha(AMPKα), Akt, GSK3β, BMAL1, and mTOR were determined. Furthermore, 20 μmol·L~(-1) CLK8 was added to measure the glucose consumption as well as the protein levels of ChREBP, PPARα, and mTOR in IR-HepG2 cells. The results showed that berberine increased the glucose consumption, lowered the lipid levels, increased the expression and nuclear localization of BMAL1 and CLOCK, and up-regulated the level of BMAL1 in IR-HepG2 cells.

In recent years, the sustainable utilization of TCM resources has received high attention and acquired a series of significant achievements in resource survey, quality evaluation, resource protection, innovative technology, and development and utilization, which effectively promoted the sustainable utilization of TCM resources and high-quality development of the TCM industry. The most urgent issue currently is to shift the focus of the research on the sustainable utilization of TCM resources from a sustainable utilization technology system to a sustainable utilization evaluation indicator system. Therefore, in order to objectively evaluate the ability, level, and trend of the sustainable utilization of TCM resources, an evaluation indicator system for sustainable utilization of TCM resources(EIS-TCMRSU) and methods for measuring and determining various standards and indicators were innovatively constructed. With the support of economic policies and scientific regulation of TCM policies, emerging technologies and new tools and methods could be applied to achieve the strategic goals of sustainable utilization and sustainable development of TCM resources. Based on the driving force-pressure-state-impact-response(DPSIR) model, key indicators including resource driving force, environmental pressure, resource state, socio-economic impact, and management response were determined by analyzing the industry chain bottleneck problems and development factors related to the sustainable utilization of TCM resources. According to the scientific, systematic, comparable, dynamic, and operable principles, the EIS-TCMRSU theoretical system was constructed to accurately reflect the ability and development trend of the sustainable utilization of TCM resources and promote the EIS-TCMRSU research from theoretical exploration to practical application. It ensured objective evaluation of the level and ability of sustainable utilization of TCM resources and provided a theoretical basis and practical guidance for the sustainable utilization and sustainable development of TCM resources.

All groups were given the drug for four weeks, with the diameter of their knee joint being measured during this period. Hematoxylin-eosin staining and Senna solid green staining were utilized to observe the pathology of knee joint tissue in SD rats. The initial therapeutic impact of Zhengqing Fengtongning Sustained-release Tablets on knee osteoarthritis in rats was assessed by monitoring the levels of interleukin-1β(IL-1β) and interleukin-6(IL-6) in the plasma. Using a combination of non-targeted metabolomics and 16S rRNA techniques, researchers determined the variations in endogenous molecules and intestinal flora in rats and identified potential biomarkers. The results showed that Zhengqing Fengtongning Sustained-release Tablets improved the diameter of knee joint swelling, ameliorated the pathological damage of cartilage tissue, and reduced the plasma levels of IL-1β and IL-6 in rats with knee osteoarthritis. Metabolomics analysis identified 22 potential biomarkers associated with the modulatory effects of Zhengqing Fengtongning Sustained-release Tablets, including 5-hydroxytryptamine, corticosterone, methylmalonic acid, and other biomarkers, which were mainly involved in eight metabolic pathways, including tryptophan metabolism, vitamin K metabolism, steroid synthesis, and so on.
