Environment-friendly organic coordination design of Z-scheme heterojunction N-BOB/BiOIO 3 for efficient LED-light-driven photocatalytic and electrochemical performance. CHEMOSPHERE 2023; 341:140101. [PMID: 37690557 DOI: 10.1016/j.chemosphere.2023.140101] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 08/23/2023] [Accepted: 09/05/2023] [Indexed: 09/12/2023]
Abstract
As the climate seriously changes, ecofriendly nanomaterials have attracted tremendous interest in renewable energy as photocatalysis. Herein, we designed a new green bismuth-based Z-scheme Bi2O22+ slabs coordinate with 2-aminoterephthalic acid (N-BOB)/BiOIO3 through a simple anion exchange and postsynthetic hydrothermal reaction. FTIR, XRD, FESEM and TEM were employed to characterize the functional groups, structure, and morphologies. UV-DRS revealed the difference in band energy of the N-BOB and N-BOB/BiOIO3. Toward Rh B, TC and CIP degradation tests, 1-N-BOB/BiOIO3 manifests the best photocatalytic degradation (52.3%, 63.6% and 30.2%) efficiency. Also, 1-N-BOB/BiOIO3 possesses high durability in photocatalytic reactions and can inhibit 32.3% of bacterial growth. The results indicate that the synergistic effect between surface amine groups and Z-scheme heterojunction harvests light absorption to increase solar-to-energy (STE) efficiency, accelerate the charge separation, and increases the active sites with high photoredox potential, thus improving the photocatalytic performance. ROS scavenging tests further elucidated that photogenerated holes and hydroxyl radicals play a critical role. In addition, the surface amine groups and benzene rings can be utilized for supercapacitors and other multidisciplinary applications. 0.5 N-BOB/BiOIO3/GO impressively showed 5 times higher specific capacitance than pure GO electrode. We hope this work provides new sight into designing green nanomaterials to relieve environmental pollution and leave behind a clean future for the next generation.

Abstract
Bruton tyrosine kinase (BTK) is linked to multiple signalling pathways that regulate cellular survival, activation, and proliferation. A covalent BTK inhibitor has shown favourable outcomes for treating B cell malignant leukaemia. However, covalent inhibitors require a high reactive warhead that may contribute to unexpected toxicity, poor selectivity, or reduced effectiveness in solid tumours. Herein, we report the identification of a novel noncovalent BTK inhibitor. The binding interactions (i.e. interactions from known BTK inhibitors) for the BTK binding site were identified and incorporated into a structure-based virtual screening (SBVS). Top-rank compounds were selected and testing revealed a BTK inhibitor with >50% inhibition at 10 µM concentration. Examining analogues revealed further BTK inhibitors. When tested across solid tumour cell lines, one inhibitor showed favourable inhibitory activity, suggesting its potential for targeting BTK malignant tumours. This inhibitor could serve as a basis for developing an effective BTK inhibitor targeting solid cancers.

Abstract
In this work, we demonstrated that building different linking groups between nanodiamond (ND) and TiO2 (P25) could provide more effective protection under oxidative stress and ultraviolet (UV) light irradiation compared with the use of TiO2 alone. The establishment of ester (-C-O-O-R), amide (-CONH-), and epoxide-amine adduct (-NHCCO-) groups between ND-TiO2 composites was found to be critical in the generation of reactive oxygen species (ROS) by controlling their charge transfer behaviors. We hypothesized that linking groups between the composites dictate the performance of ROS generation from nano-TiO2 under UV-light irradiation due to the differences in linking groups. The results showed that hydroxyl radicals were attenuated by the incorporation of ND. An MTT cell proliferation assay was performed in human cells under the treatment of ND-TiO2 composites to investigate the impacts of composites on cell viability. The results from the luciferase reporter assay suggested they have anti-inflammatory activity and can reduce cellular DNA damage under ROS stimulation. A zebrafish model was also applied with the ND-TiO2 composite treatment to demonstrate the safety aspects of the composites in vivo and their biomedical application potential. Studies exploring ROS generation behaviors in different linking groups suggested that interactive functionalization between nanoparticles might be an ideal antioxidant and anti-inflammatory strategy.

Abstract
Colon cancer is a common human cancer worldwide. The survival rate of late staged or metastatic colon cancer patients remains low even though the effectiveness of treatment in colon cancer has greatly improved. Research on tumorigenesis mechanisms and discovery of novel molecular target for treating colon cancer is critical. The promotion roles of WHSC1 in multiple myeloma have been demonstrated previously, yet, the regulation of WHSC1 in other cancers is largely unknown, especially in colon cancer. Here, in this study, we analyzed and identified WHSC1 while studying the genetic regulations of HMGA2 in colon cancer cells by microarray analysis, and investigated the HMGA2-WHSC1 interaction. We then applied CRISPR technology to establish stable WHSC1 knockout cells, to address the functional regulation of WHSC1 in colon cancer. In summary, our results for the first time identified the HMGA2-WHSC1 interaction in colon cancer. Moreover, we discovered that WHSC1 promotes cancer proliferation, facilitates resistance of chemotherapy agent, and promotes metastatic capacity of colon cancer.

Fullerene C60 Protects Against Intestinal Injury from Deoxynivalenol Toxicity by Improving Antioxidant Capacity. Life (Basel) 2021; 11:life11060491.

Abstract
Oxidative stress is involved in a wide variety of pathologies, and fullerene has been shown to have an antioxidant ability. Mycotoxins exert toxic effects through induction of excessive reactive oxygen species (ROS). Here, we evaluated water-soluble fullerene C60 for its anti-mycotoxin and antioxidant effects in vitro and in vivo. Intestinal epithelial cells were cultured with fullerene during deoxynivalenol (DON) exposure. The results revealed that fullerene C60 significantly promoted cell viability, decreased apoptosis and necrotic cell number, and significantly reduced intracellular ROS levels during DON exposure (p < 0.05). To investigate the role of fullerene in antioxidant capacity in vivo further, 40 three-week-old male C57BL/6 mice were randomly divided into four groups. There were no significant differences between the control and fullerene groups (p > 0.05). In mice exposed to DON, supplementation with fullerene C60 significantly improved growth performance, and enhanced the total antioxidant status and the activities of SOD and GPX in the intestine and liver (p < 0.05). In addition, fullerene C60 supplementation improved intestinal morphology, as indicated by a higher villus height and tight junction protein expression (p < 0.05). Furthermore, fullerene supplementation decreased serum concentrations of inflammatory cytokine and lipopolysaccharide (LPS; a penetrability marker) compared to the DON-challenged group (p < 0.05). The current study suggests that fullerene C60 improves intestinal antioxidant status against DON-induced oxidative stress in vitro and in vivo.

Abstract
The concept of nanoscale materials and their applications in industrial technologies, consumer goods, as well as in novel medical therapies has rapidly escalated in the last several years. Consequently, there is a critical need to understand the mechanisms that drive nanomaterials biocompatibility or toxicity to human cells and tissues. The ability of nanomaterials to initiate cellular pathways resulting in oxidative stress has emerged as a leading hypothesis in nanotoxicology. Nevertheless, there are a few examples revealing another face of nanomaterials - they can alleviate oxidative stress via decreasing the level of reactive oxygen species. The fundamental structural and physicochemical properties of carbonaceous nanomaterials that govern these anti-oxidative effects are discussed in this article. The signaling pathways influenced by these unique nanomaterials, as well as examples of their applications in the biomedical field, e.g. cell culture, cell-based therapies or drug delivery, are presented. We anticipate this emerging knowledge of intrinsic anti-oxidative properties of carbon nanomaterials to facilitate the use of tailored nanoparticles in vivo.

Photocatalytic Cleavage of β- O-4 Ether Bonds in Lignin over Ni/TiO 2. Molecules 2020; 25:molecules25092109.

Abstract
It is of great importance to explore the selective hydrogenolysis of β-O-4 linkages, which account for 45–60% of all linkages in native lignin, to produce valued-added chemicals and fuels from biomass employing UV light as catalyst. TiO2 exhibited satisfactory catalytic performances in various photochemical reactions, due to its versatile advantages involving high catalytic activity, low cost and non-toxicity. In this work, 20 wt.% Ni/TiO2 and oxidant PCC (Pyridinium chlorochromate) were employed to promote the cleavage of β-O-4 alcohol to obtain high value chemicals under UV irradiation at room temperature. The Ni/TiO2 photocatalyst can be magnetically recovered and efficiently reused in the following four consecutive recycling tests in the cleavage of β-O-4 ether bond in lignin. Mechanism studies suggested that the oxidation of β-O-4 alcohol to β-O-4 ketone by oxidant PCC first occurred during the reaction, and was followed by the photocatalysis of the obtained β-O-4 ketone to corresponding acetophenone and phenol derivates. Furthermore, the system was tested on a variety of lignin model substrates containing β-O-4 linkage for the generation of fragmentation products in good to excellent results.

Abstract
Colon cancer is one of the leading causes of cancer-related deaths and its five-year survival rate remains low in locally advanced or metastatic stages of colon cancer. Overexpression of high mobility group protein AT-hook2 (HMGA2) is associated with cancer progression, metastasis, and poor prognosis in many malignancies. Oxidative stress regulates cellular mechanisms and provides an environment that favors the cancer cells to survive and progress, yet, at the same time, oxidative stress can also be utilized as a cancer-damaging strategy. The molecular regulatory roles of HMGA2 in oxidative stress and their involvement in cancer progression are largely unknown. In this study, we investigated the involvement of HMGA2 in regulation of oxidative stress responses by luciferase reporter assays. Moreover, we utilized dicoumarol (DIC), a derivative of coumarin which has been suggested to be involved in oxidation regulation with anticancer effects, and demonstrated that DIC could induce apoptosis and inhibit cell migration of HMGA2 overexpressing colon cancer cells. Further investigation also evidenced that DIC can enhance the cancer inhibition effect of 5-FU in colony formation assays. Taken together, our data revealed novel insights into the molecular mechanisms underlying HMGA2 and highlighted the possibility of targeting the cellular antioxidant system for treating patients and preventing from cancer progression in HMGA2 overexpressing colon cancer cells.

Abstract
Giving patients right dosage is an essential concept of precision medicine. Most of nanocarriers lack of flexible drug capacity and structural stability to be customized for specific treatment, resulting in low therapeutic efficacy and unexpected side effects. Thus, a growing need emerges for fast and rigorous approaches to develop nanoparticles with properties of adjustable dosage and controllable particle size. Poly-l-Lysine is known for its enhanced bioadhesivity and pH-triggered structural swelling effect, which is utilized as the main agent to activate the multistage drug releasing. Inspired by natural bio-assembly system, we report a simple method to self-assemble Poly-l-Lysine-based nanoparticles via supramolecular recognitions of cross-linked pyrenes, which provides noncovalent force to flexibly encapsulate Doxorubincin and to construct robust nanostructures. Pyrene-modified polypeptide self-assemblies are able to adjust drug payload from 1: 10 to 2:1 (drug: polypeptide) without changing its uniform nano-spherical morphology. This nanostructure remained the as-made morphology even after experiencing the long-term (~ 10 weeks) storage at room temperature. Also, the nanoparticles displayed multi-step drug release behaviours and exhibited great in vitro and in vivo cytotoxicity towards colon cancer cells. The as-mentioned nanoparticles provide a novel perspective to compensate the clinical needs of specific drug feedings and scalable synthesis with advantages of simple-synthesis, size-adaptivity, and morphology reversibility.
