Abstract
Aluminium (Al) is one of the most popular materials for industrial and domestic use. Nevertheless, research has proven that this metal can be toxic to most organisms. This light metal has no known biological function and to date very few aluminium-specific biological pathways have been identified. In addition, information about the impact of this metal on microbial life is scarce. Here, we aimed to study the effect of aluminium on the metal-resistant soil bacterium Cupriavidus metallidurans CH34 in different growth modes, i.e. planktonic cells, adhered cells and mature biofilms. Our results indicated that despite a significant tolerance to aluminium (minimal inhibitory concentration of 6.25 mM Al₂(SO₄)₃.18H₂O), the exposure of C. metallidurans to a sub-inhibitory dose (0.78 mM) caused early oxidative stress and an increase in hydrolytic activity. Changes in the outer membrane surface of planktonic cells were observed, in addition to a rapid disruption of mature biofilms. On protein level, aluminium exposure increased the expression of proteins involved in metabolic activity such as pyruvate kinase, formate dehydrogenase and poly(3-hydroxybutyrate) polymerase, whereas proteins involved in chemotaxis, and the production and transport of iron scavenging siderophores were significantly downregulated.

Lv QZ, Zhang XL, Gao L, Yan L, Jiang YY. iTRAQ-based proteomics revealed baicalein enhanced oxidative stress of Candida albicans by up-regulating CPD2 expression. Med Mycol 2022; 60:6687814. [PMID: 36055797 DOI: 10.1093/mmy/myac053] [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: 01/19/2022] [Revised: 05/05/2022] [Accepted: 08/31/2022] [Indexed: 11/13/2022] Open
Abstract
Baicalein could inhibit the growth and biofilm formation of Candida albicans, the most common clinical fungal pathogen. However, the antifungal mechanism of baicalein has not been elucidated. In this study, isobaric tags for relative and absolute quantification (iTRAQ) was used to verify the mechanism of antifungal fluconazole and baicalein. A total of 58 common proteins were detected in cells treated with fluconazole. These proteins encompassed fluconazole-targeted sterol synthesis pathway, including Erg11p, Erg6p, Erg3p, Erg25p, Erg5p, Erg10p and Ncp1p. Next, iTRAQ was applied to the comparison of baicalein-treated C. albicans proteins, which detected 16 common proteins. The putative NADH dehydrogenase Cpd2p and the ATP-binding cassette transporter Snq2p were the most up-regulated proteins with the treatment of baicalein. Our results showed that CPD2 disruption elevated C. albicans resistance to baicalein significantly both in vitro and in vivo. Further in-depth studies revealed that CPD2 disruption reduced the activation of C. albicans metacaspase and partially restored the mitochondrial membrane potential reduction caused by the treatment of baicalein, which indicated that CPD2 was involved in the apoptosis induced by baicalein. Consistently, under the treatment of baicalein, CPD2Δ/Δ mutant produced lower reactive oxygen species (ROS) that was critical in causing oxidative damage and apoptosis in C. albicans. These results indicated that baicalein could increase intracellular oxidative damage by up-regulating the expression of Cpd2p so as to inhibit the growth of C. albicans, which provides new insights for investigating the antifungal target of baicalein.

Abstract
Aluminum (Al) toxicity is one of the most important limiting factors for crop yield in acidic soils. Bound Al gets converted into a toxic ionic state (Al3+) in acidic soil. Recent studies have shown that Al can act on the cell walls, cell membranes, organelles, and nuclei of microorganisms and affect substance and energy metabolism. To explore the gene expression at the transcriptional level under Al stress, we sequenced the transcriptome of Cryptococcus humicola, which is a highly Al-resistant yeast strain isolated from acidic soil and tolerates up to 200 mM Al3+. The screening conditions for genes from the control and experimental group were a false discovery rate (FDR) <0.05 and log 2|FC| > 1. A total of 4760 genes were differentially expressed, among which 3066 were upregulated and 1694 were downregulated. These genes control glycometabolism, protein synthesis, lipid metabolism and signalling pathways. Eleven selected differentially expressed genes were further validated using qRT-PCR. The results suggested that Al stress leads to complex responses in C. humicola. The effects of Al on the β-d-glucan and mannose contents and Al accumulation in the cell wall were determined. With an increase in the Al treatment time and concentration, the contents of β-d-glucan and mannose showed a trend of first increasing and then decreasing. Under Al treatment, the Al content of the cell wall also showed a trend of first increasing and then decreasing. These results suggested that Al accumulates in the cell wall and the cell wall plays a vital role in the Al resistance of C. humicola. The differentially expressed genes provide a foundation for the further study of Al tolerance in C. humicola.

Abstract
To understand the molecular mechanism involved in the survivability of cold-tolerant lactic acid bacteria was of great significance in food processing, since these bacteria play a key role in a variety of low-temperature fermented foods. In this study, the cold-stress response of probiotic Lactobacillus plantarum K25 isolated from Tibetan kefir grains was analyzed by iTRAQ proteomic method. By comparing differentially expressed (DE) protein profiles of the strain incubated at 10°C and 37°C, 506 DE proteins were identified. The DE proteins involved in carbohydrate, amino acid and fatty acid biosynthesis and metabolism were significantly down-regulated, leading to a specific energy conservation survival mode. The DE proteins related to DNA repair, transcription and translation were up-regulated, implicating change of gene expression and more protein biosynthesis needed in response to cold stress. In addition, two-component system, quorum sensing and ABC (ATP-binding cassette) transporters also participated in cell cold-adaptation process. These findings provide novel insight into the cold-resistance mechanism in L. plantarum with potential application in low temperature fermented or preserved foods.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Curcuma wenyujin Y.H. (CW), a variety of Curumae Rhizoma, which documented in China Pharmacopeia, has long been used as plant medicine for its traditional effect on promoting Qi, activating blood stagnation and expelling blood stasis. Nowadays, it is often used in clinic for extraordinary effect on liver diseases. It is worthy to be noted that CW processed with vinegar has been applied in clinic for 1500 years which started in the northern and southern dynasties. AIM OF STUDY Liver fibrosis is a worldwide clinical issue. It is worth developing a multi-target and multicellular approach which is high efficiency and low side effects for the treatment of hepatic fibrosis. The anti-hepatic fibrosis molecular mechanisms of CW and vinegar Curcuma wenyujin (VCW) need to be explored and elucidated. Furthermore, the study aimed to discuss the efficiency and mechanism differences between CW and VCW in hepatic fibrosis. METHODS AND RESULTS Biochemical assays and histopathology were adopted to evaluate the anti-hepatic fibrosis effect of CW and VCW. The TGF-β/Smad signaling involving TGF-β1, TGF-βRⅠ, TGF-βRⅡ and Smad2, Smad3, Smad7 in fibrosis is examined, which is a critical step towards the evaluation of anti-hepatic fibrosis agents. Meanwhile, the MMP/TIMP balance is a potential therapy target by modulating extracellular matrix, which is also examined. Both CW and VCW inhibit the activation and proliferation of hepatic stellate cells and induce apoptosis via blocking TGF-β/Smad signaling pathways. Additionally, the level of MMP-2/TIMP-1 regulated significantly, which suggest CW and VCW participate in the degradation process, and maintain the formation and production of extracellular matrix. CONCLUSION Raw and vinegar processed Curcuma wenyujin regulates hepatic fibrosis via bloking TGF-β/Smad signaling pathways and up-regulation of MMP-2/TIMP-1 ratio. And VCW has more exhibition than CW.

Abstract
We isolated Cryptococcus sp. T1 from Lake Tazawa's acidic water in Japan. Cryptococcus sp. T1 neutralized an acidic casamino acid solution (pH 3.0) and released ammonia from the casamino acids to aid the neutralization. The neutralization volume was estimated to be approximately 0.4 mL/h. The casamino acids' amino acids decreased (1.24→0.15 mM); ammonia increased (0.22→0.99 mM). We neutralized acidic drainage water (1 L) from a Tamagawa River neutralization plant, which was run through the column with the T1-immobilized alginate beads at a flow rate of 0.5 mL/min, and observed that the viscosity, particle size and amounts of the alginate beads affected the acidic drainage neutralization with an increase of the pH value from 5.26 to 6.61 in the last fraction. An increase in the Al concentration decreased Cryptococcus sp. T1's neutralization ability. After 48 h, the pH of acidic water with 50 mg/L Al was apparently lower than that without Al. Almost no pH increase was observed at 75 mg/L.

Abstract
Tang-luo-ning (TLN) is a traditional Chinese herbal recipe for treating diabetic peripheral neuropathy (DPN). In this study, we investigated mitochondrial protein profiles in a diabetic rat model and explored the potential protective effect of TLN. Diabetic rats were established by injection of streptozocin (STZ) and divided into model, alpha lipoic acid (ALA), and TLN groups. Mitochondrial proteins were isolated from dorsal root ganglia and proteomic analysis was used to quantify the differentially expressed proteins. Tang-luo-ning mitigated STZ-induced diabetic symptoms and blood glucose level, including response time to cold or hot stimulation and nerve conductive velocity. As compared to the normal, there were 388 differentially expressed proteins in the TLN group, 445 in ALA group, and 451 in model group. As compared to the model group, there were 275 differential proteins in TLN group and 251 in ALA group. As compared to model group, mitochondrial complex III was significantly decreased, while glutathione peroxidase and peroxidase were increased in TLN group. When compared with ALA group, the mitochondrial complex III was increased, and mitochondrial complex IV was decreased in TLN group. Together, TLN should have a strong antioxidative activity, which appears to be modulated through regulation of respiratory complexes and antioxidases.

Abstract
Opportunistic fungal infections are an increasing threat for global health, and for immunocompromised patients in particular. These infections are characterized by interaction between fungal pathogen and host cells. The exact mechanisms and the attendant variability in host and fungal pathogen interaction remain to be fully elucidated. The field of systems biology aims to characterize a biological system, and utilize this knowledge to predict the system's response to stimuli such as fungal exposures. A multi-omics approach, for example, combining data from genomics, proteomics, metabolomics, would allow a more comprehensive and pan-optic "two systems" biology of both the host and the fungal pathogen. In this review and literature analysis, we present highly specialized and nascent methods for analysis of multiple -omes of biological systems, in addition to emerging single-molecule visualization techniques that may assist in determining biological relevance of multi-omics data. We provide an overview of computational methods for modeling of gene regulatory networks, including some that have been applied towards the study of an interacting host and pathogen. In sum, comprehensive characterizations of host-fungal pathogen systems are now possible, and utilization of these cutting-edge multi-omics strategies may yield advances in better understanding of both host biology and fungal pathogens at a systems scale.
