Abstract :

The white rot fungus Cerrena unicolor 87613 has been previously shown to be a promising resource in laccase production, an enzyme with significant biotechnological applications. Conventional methods face technical challenges in improving laccase activity. Attempts are still being made to develop novel approaches for further enhancing laccase activity. This study aimed to understand the regulation of laccase activity in C. unicolor 87613 for a better exploration of the novel approach. Transcriptomic and metabolomic analyses were performed to identify key genes and metabolites involved in extracellular laccase activity. The findings indicated a strong correlation between the glutathione metabolism pathway and laccase activity. Subsequently, experimental verifications were conducted by manipulating the pathway using chemical approaches. The additive reduced glutathione (GSH) dose-dependently repressed laccase activity, while the GSH inhibitors (APR-246) and reactive oxygen species (ROS) inducer (H2O2) enhanced laccase activity. Changes in GSH levels could determine the intracellular redox homeostasis in interaction with ROS and partially affect the expression level of laccase genes in C. unicolor 87613 in turn. In addition, GSH synthetase was found to mediate GSH abundance in a feedback loop. This study suggests that laccase activity is negatively influenced by GSH metabolism and provides a theoretical basis for a novel strategy to enhance laccase activity by reprogramming glutathione metabolism at a specific cultivation stage.

Abstract :

OBJECTIVE: To investigate the effects of emodin on alkali burn -induced corneal inflammation and neovascularization. METHODS: The ability of emodin to target vascular endothelial growth factor receptor 2 (VEGFR2) was predicted by molecular docking. The effects of emodin on the invasion, migration, and proliferation of human umbilical vein endothelial cells (HUVEC) were determined by cell counting kit -8, Transwell, and tube formation assays. Analysis of apoptosis was performed by flow cytometry. CD31 levels were examined by immunofluorescence. The abundance and phosphorylation state of VEGFR2, protein kinase B (Akt), signal transducer and activator of transcription 3 (STAT3), and P38 were examined by immunoblot analysis. Corneal alkali burn was performed on 40 mice. Animals were divided randomly into two groups, and the alkali -burned eyes were then treated with drops of either 10 mu M emodin or phosphate buffered saline (PBS) four times a day. Slit - lamp microscopy was used to evaluate inflammation and corneal neovascularization (CNV) in all eyes on Days 0, 7, 10, and 14. The mice were killed humanely 14 d after the alkali burn, and their corneas were removed and preserved at -80 celcius until histological study or protein extraction. RESULTS: Molecular docking confirmed that emodin was able to target VEGFR2. The findings revealed that emodin decreased the invasion, migration, angiogenesis, and proliferation of HUVEC in a dose -dependent manner. In mice, emodin suppressed corneal inflammatory cell infiltration and inhibited the development of corneal neovascularization induced by alkali burn. Compared to those of the PBS -treated group, lower VEGFR2 expression and CD31 levels were found in the emodin- treated group. Emodin dramatically decreased the expression of VEGFR2, p-VEGFR2, p-Akt, p-STAT3, and p -P38 in VEGF-treated HUVEC. CONCLUSION: This study provides a new avenue for evaluating the molecular mechanisms underlying corneal inflammation and neovascularization. Emodin might be a promising new therapeutic option for corneal alkali burns.

Abstract :

目的:观察益景汤拮抗高糖诱导的体外血-视网膜内屏障(iBRB)模型基底膜(BM)损害及机制。方法:分离、培养大鼠内皮细胞(ECs)和视网膜微血管周细胞(RMPs)构建体外iBRB模型,随机分成低糖组、高糖组、米诺环素组、益景汤组,分别予25 mmol/L葡萄糖、60 mmol/L葡萄糖、60 mmol/L葡萄糖+10μg/mL米诺环素、60 mmol/L葡萄糖+10%益景汤含药血清干预,各组干预12 h后终止孵育。采用Western blot法检测各组BM相关蛋白[Ⅳ型胶原(collagenⅣ, CⅣ)、层黏连蛋白(laminin, LN)]及MMPs/TIMPs相关蛋白(MMP-2、MMP-3、MMP-9、TIMP-1、TIMP-2)的表达。结果:与低糖组相比,高糖组、米诺环素组、益景汤组CⅣ蛋白表达增加,高糖组、米诺环素组LN蛋白表达增加(均P<0.05)。益景汤及米诺环素能够抑制高糖诱导的CⅣ、LN蛋白表达增加,益景汤组、米诺环素组与高糖组相比具有差异(均P<0.05)。与低糖组相比,高糖组、米诺环素组MMP-2、MMP-3、MMP-9蛋白表达增加(均P<0.05)。益景汤能够抑制高糖诱导的MMP-2、MMP-3、MMP-9蛋白表达增加,益景汤组与高糖组相比具有差异(均P<0.05)。低糖组、高糖组、米诺环素组、益景汤组各组之间TIMP-1、TIMP-2表达未见明显差异(均P>0.05)。结论:益景汤可能通过调控MMP-2、MMP-3、MMP-9、CⅣ、LN的表达,干预高糖介导的BM重塑,抑制iBRB的损害,从而干预DR。

A complex metabolic network and its biomarkers regulate laccase production in white-rot fungus Cerrena unicolor 87613 Scopus

Abstract :

Background: White-rot fungi are known to naturally produce high quantities of laccase, which exhibit commendable stability and catalytic efficiency. However, their laccase production does not meet the demands for industrial-scale applications. To address this limitation, it is crucial to optimize the conditions for laccase production. However, the regulatory mechanisms underlying different conditions remain unclear. This knowledge gap hinders the cost-effective application of laccases. Results: In this study, we utilized transcriptomic and metabolomic data to investigate a promising laccase producer, Cerrena unicolor 87613, cultivated with fructose as the carbon source. Our comprehensive analysis of differentially expressed genes (DEGs) and differentially abundant metabolites (DAMs) aimed to identify changes in cellular processes that could affect laccase production. As a result, we discovered a complex metabolic network primarily involving carbon metabolism and amino acid metabolism, which exhibited contrasting changes between transcription and metabolic patterns. Within this network, we identified five biomarkers, including succinate, serine, methionine, glutamate and reduced glutathione, that played crucial roles in co-determining laccase production levels. Conclusions: Our study proposed a complex metabolic network and identified key biomarkers that determine the production level of laccase in the commercially promising Cerrena unicolor 87613. These findings not only shed light on the regulatory mechanisms of carbon sources in laccase production, but also provide a theoretical foundation for enhancing laccase production through strategic reprogramming of metabolic pathways, especially related to the citrate cycle and specific amino acid metabolism. © The Author(s) 2024.

Abstract :

为研究外源酶对陈年武夷岩茶挥发性成分的影响,运用气相色谱-质谱联用技术(gas chromatography-mass spectrometry,GC-MS)、感官评价和香气活性值(odor activity value,OAV)方法对酶处理后的武夷岩茶进行分析.GC-MS分析结果表明,纤维素酶、果胶酶、漆酶和β-葡萄糖苷酶质量比为2:1:2:3时有利于香气物质的释放,尤其对醇类、酯类及酮类香气物质释放贡献较大.感官评价和OAV值的结果表明,酶的添加能明显提高武夷岩茶的花香、甜香和木香,复合酶的处理效果最佳,其次是β-葡萄糖苷酶.经复合酶处理后己醛、2-己烯醛和(E,E)-2,4-己二烯醛等物质含量降低,OAV减小.上述研究表明,纤维素酶、果胶酶、漆酶、β-葡萄糖苷酶及其复合酶的添加均可明显改善陈年武夷岩茶香气品质.

Abstract :

•AIM: To observe the effect of soluble glycoprotein 130 (sgp130) on expression of p - STAT3 and vascular endothelial growth factor (VEGF) - A in retina of mice with diabetes mellitus (DM), and explore the possibility of sgp130 in interfering with inflammatory damage of diabetic retinopathy (DR). •METHODS: A total of 45 mice were randomly divided into normal group, DM group and sgp130 group. DM models were made in DM group and sgp130 group with streptozotocin. No special intervention was given to normal group and DM group, but sgp130 group was given intravitreal injection of 1.5mg/mL sgp130 2μ L at the 1 and 5wk. After 10wk, all the mice were sacrificed to assess the protein expression of interleukin 6 (IL - 6), p - STAT3 and VEGF- A in the retina. • RESULTS: The expressions of IL - 6, p - STAT3 and VEGF- A in retina of DM group were higher than those of normal group at 10wk (all P < 0.01). The expression of p - STAT3 and VEGF - A in sgp130 group were lower than those in DM group (all P< 0.01). • CONCLUSION: The sgp130 can selectively antagonize the trans signal transduction pathway of IL - 6, down - regulate the expression of downstream inflammatory factors VEGF- A, and it may be used in the intervention of retinal inflammatory damage related with IL- 6 in DM. © 2023 International Journal of Ophthalmology (c/o Editorial Office).
