Zhang J, Ye L, Chen Q, Wang F. Response analysis of Pinus sibirica to pine wood nematode infection through transcriptomics and metabolomics study. FRONTIERS IN PLANT SCIENCE 2024; 15:1383018. [PMID: 38774221 PMCID: PMC11106439 DOI: 10.3389/fpls.2024.1383018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Accepted: 04/15/2024] [Indexed: 05/24/2024]
Abstract
Pinus sibirica is primarily distributed in Siberia. Owing to its excellent cold resistance and development potential, it has become an important introduced tree species in the Greater Xing'an area of China. Pine wilt disease, triggered by the pine wood nematode (PWN, Bursaphelenchus xylophilus), constitutes a profoundly critical affliction within forest ecosystems. Its incidence has extended to the northeastern region of China in recent years. To explore the potential host status of P. sibirica in the Greater Xing'an area for PWN and to elucidate the responses following inoculation, artificial inoculation, transcriptomics, and metabolomics methods were used. In the artificial inoculation experiments, quantitative analysis of nematode populations within the trees demonstrated that PWN exhibited normal growth and reproductive capabilities within P. sibirica. Subsequently, transcriptome and metabolome sequencing were conducted at four time points before disease onset (3-, 5-, 7-, and 9-days post inoculation). Gene trend analysis and differentially expressed gene screening were employed and the results indicated that genes associated with the flavonoid biosynthesis pathway exhibited predominant enrichment among the up-regulated genes. Metabolome analysis showed that the abundance of flavonoid-related metabolites in P. sibirica increased after inoculation with PWN. Integrated analysis of transcriptome and metabolome revealed that after PWN inoculation in P. sibirica, two chalcone synthase (chs) genes and a chalcone isomerase (chi) gene were significantly upregulated, and the upregulation should accumulate naringenin, pinocembrin, and apigenin to help P. sibirica resist infection of PWN. The results suggested that flavonoid biosynthesis pathway continued to respond after P. sibirica was infected with PWN and played an important role in the interaction between P. sibirica and PWN.

Abstract
Myrceugenia foveolata, commonly known as 'guamirim', was analysed using UHPLC-MS/MS and molecular networking. Hydroalcoholic extracts of leaves and stem bark were obtained using ethanol:water (70:30) as solvent. Chemical composition of the extracts was identified using UHPLC-MS/MS and tested for antioxidant activity and growth inhibition against E. coli, S. aureus, L. monocytogenes and S. enterica. Ten compounds were tentatively identified in the extracts including myricitrin, quercitrin, and betulin (in leave extracts), and avicularin, kaemferol-3-O-arabinopyroniside, 2"-O-galloylquercitrin and the acid triterpenes ursolic, sumaresinolic, asiatic and maslinic (in both extracts). Both extracts showed similar antioxidant activities, phenolic composition, and growth inhibition. The most pronounced response was observed against L. monocytogenes, with a growth inhibition rate of 73% to leaves extract and 65% do stem bark extract.

Abstract
Pinocembrin (5,7-dihydroxyflavone) is a major flavonoid found in many plants, fungi and hive products, mainly honey and propolis. Several in vitro and preclinical studies revealed numerous pharmacological activities of pinocembrin including antioxidant, anti-inflammatory, antimicrobial, neuroprotective, cardioprotective and anticancer activities. Here, we comprehensively review and critically analyze the studies carried out on pinocembrin. We also discuss its potential mechanisms of action, bioavailability, toxicity, and clinical investigations. The wide therapeutic window of pinocembrin makes it a promising drug candidate for many clinical applications. We recommend some future perspectives to improve its pharmacokinetic and pharmacodynamic properties for better delivery that may also lead to new therapeutic advances.

Abstract
Obesity is currently the most common cause of metabolic diseases including type 2 diabetes and hyperlipidemia. Obesity results from excess lipid accumulation in adipose tissue. Several studies have investigated the inhibitory effects of natural plant-derived products on adipocyte differentiation and lipid accumulation. In this study, we examined the effect of hydrolysable tannins composed of gallic acid and glucose on adipocyte differentiation in 3T3-L1 cells. 1,2,3,4,6-Penta-O-galloyl-β-D-glucose (PGG) (1), a representative gallotannin, inhibited lipid accumulation in 3T3-L1 cells, whereas ellagitannins (tellimagrandin I, eugeniin and casuarictin) did not. The expression of adipocyte differentiation-related genes, including peroxisome proliferator activator γ2 (Pparγ2), CCAAT/enhancer binding protein α (C/EBPα) and adipocyte fatty acid binding protein (aP2), was significantly suppressed in PGG (1)-treated 3T3-L1 cells beginning at day 2 after induction of differentiation. While PGG (1) did not directly reduce Pparγ2 expression, it reduced the expression of its target genes in mature adipocytes. In addition, PGG (1) treatment inhibited mitotic clonal expansion, one of earliest events of adipocyte differentiation. These findings indicate that PGG (1) has an inhibitory effect on adipocyte differentiation through the suppression of mitotic clonal expansion.

Abstract
Obesity is a risk factor for many diseases, including type 2 diabetes and cardiovascular disease, and is related to the rising morbidity and mortality. Discovery of agents targeting adipogenesis, especially from natural sources, is important for the treatment of obesity. Here, we aimed to identify anti-adipogenic substances in methanol extracts of Physalis peruviana and to investigate their effect, along with underlying mechanisms. Activity-guided fractionation of the extract revealed 4β-hydroxywithanolide E (HWE) and withanolide E (WE) as the adipogenesis inhibitors. Both compounds suppressed mRNA expression of central adipogenic transcription factors, peroxisome proliferator-activated receptor γ, and CCAAT/enhancer-binding protein α in the early stage of adipocyte differentiation. The inhibitory action of these two withanolides on adipogenesis was largely limited to this stage. The proliferation of preadipocytes was markedly suppressed by treatment with HWE and WE for 24 and 48 h in the differentiation medium, and cell-cycle arrest in the G0/G1 phase was observed. Therefore, our results suggested that withanolides from P. peruviana to be novel anti-adipogenic compounds that modulate mitotic clonal expansion.

Abstract
Obesity elevates the risk of cardiovascular disease and has been strongly associated with increases in the incidence of many metabolic diseases. Therefore, prevention of obesity leads to the prevention of metabolic diseases. In light of this, substances that exert anti-obesity effects are crucial for the prevention of obesity. Indirubin, a 3,2' bisindole isomer of indigo, is the active component of the traditional Chinese medicine used for the treatment of chronic myelocytic leukemia. In particular, indirubin-3'-oxime (1) was shown to inhibit the differentiation of adipocytes. In this study, we investigated the inhibitory effects of nine indirubin-3'-oxime derivatives against lipid accumulation during differentiation in 3T3-L1 cells. Among the compounds tested, 5-methoxyindirubin-3'-oxime (2) and 6-bromoindirubin-3'-oxime (7) at 5 µM exhibited significantly stronger inhibitory activity than indirubin-3'-oxime (1). Furthermore, 5-methoxyindirubin-3'-oxime (2) and 6-bromoindirubin-3'-oxime (7) markedly suppressed the expression of CCAAT/enhancer-binding protein α, peroxisome proliferator activator γ2, and adipocyte protein 2, both of which are key adipogenic regulators at the intermediate stage of adipocyte differentiation. Our results demonstrate that 5-methoxyindirubin-3'-oxime (2) and 6-bromoindirubin-3'-oxime (7) significantly down-regulated lipid accumulation during differentiation of 3T3-L1 cells, suggesting their potential as novel therapeutic drugs against the development of obesity.

Abstract
Effects of berberine on glucose-lipid metabolism, inflammatory factors and insulin resistance in patients with metabolic syndrome were investigated. Eighty patients with metabolic syndrome treated in Linyi Central Hospital from January 2017 to December 2017 were selected and divided into control group (n=40) and observation group (n=40). Patients in control group were treated with regular therapy using the Western medicine and drugs, while those in observation group, based on the treatment in control group, were treated with berberine. Changes in relevant indexes to blood glucose and lipid metabolisms and inflammatory factors were compared between the two groups. The correlation of inflammatory factor with fasting blood glucose, insulin resistance, triglyceride and total cholesterol was analyzed. At 1 month after treatment, levels of fasting blood glucose, 2 h postprandial blood glucose, insulin resistance index and blood lipid indexes in both groups were lower than those at 1 week after treatment (P<0.05). At 1 month after treatment, levels of fasting blood glucose, 2 h postprandial blood glucose, insulin resistance index and blood lipid indexes in observation group were significantly lower than those in control group during the same period (P<0.05). Moreover, levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in both groups at 1 month after treatment were lower than those at 1 week after treatment (P<0.05), and they were lower in observation group at 1 month after treatment than those in control group during the same period (P<0.05). Finally, hs-CRP was positively correlated with fasting blood glucose, insulin resistance, total cholesterol and triglyceride. The combined application of berberine in patients with metabolic syndrome can effectively regulate blood glucose and blood lipid of patients, alleviate insulin resistance and reduce the level of inflammatory response in the body.

Abstract
Large segments of the Brazilian population still suffer from malnutrition and diet-related illnesses. In contrast, many native fruits have biodiversity and are underexploited sources of bioactive compounds and unknown to consumers. The phytochemical composition of nine underexplored Brazilian fruits was determined. Carotenoids and anthocyanins were identified and quantified by high performance liquid chromatography-photodiode array-tandem mass spectrometry (HPLC-PDA-MS/MS), and phenolic compounds and iridoids were identified by flow injection analysis-electrospray-ion trap-tandem mass spectrometry (FIA-ESI-IT-MS/MS); in total, 84 compounds were identified. In addition, the chemical structure and pathway mass fragmentation of new iridoids from jenipapo ( Genipa americana) and jatoba ( Hymenae coubaril) are proposed. The highest level of carotenoids was registered in pequi ( Caryocar brasiliense; 10156.21 μg/100 g edible fraction), while the major total phenolic content was found in cambuci ( Campomanesia coubaril; 221.70 mg GAE/100 g). Anthocyanins were quantified in jabuticaba ( Plinia cauliflora; 45.5 mg/100 g) and pitanga ( Eugenia uniflora; 81.0 mg/100 g). Our study illustrates the chemical biodiversity of underexplored fruits from Brazil, supporting the identification of new compounds and encouraging the study of more food matrixes not yet investigated.
