In the past decades, laccases had received considerable attention because of the ability to degrade various organic substances. Based on the codon preference of the <i>Pichia pastoris</i> expression system, this study optimized the gene structure of the laccase gene <i>Lcc1</i> from <i>Coprius cinerea</i> through synthetic biology methods. A new gene <i>Lcc1I</i> was synthesized and heterologously expressed in <i>P. pastoris</i>. After 3 days of cultivation in a shake flask at 30°C, the transformants produced at a yield of 890 mg L⁻¹protein. The highest production level of the recombinant laccase was 2760 U L⁻¹. The molecular mass of the recombinant laccase was estimated at 60 kDa. The enzyme showed highest activity at pH 3.4 and 45°C. It possessed better stability at higher pH and lower temperature condition. Using 2,2'-azino-bis-(3-ethylbenzothiazoline)−6-sulphonate (ABTS) as the substrate, the <i>K</i>_m and <i>V</i>_max values were 0.136 mM and 9778 μM min⁻¹ mg⁻¹, respectively. The recombinant laccase could directly oxidize some triphenylmethane dyes like leuco-crystal violet (LCV) and leuco-malachite green (LMG). With the help of ABTS mediator, it could oxidize and degrade 77.7% crystal violet (CV) and 79.2% malachite green (MG) within 1 h. Our results indicate that optimization of the laccase gene achieves good expression results in the host system. The dye degradation model constructed in this study may also be applied to the degradation of other organic pollutants and toxic substances, providing new solutions for environmental remediation against the increasingly severe environmental pollution.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142449053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some literature also points toward its anticancer effect in different experimental models. The current study aimed to address a clinical concern on the therapeutic utilization of yohimbine as a repurposed drug. We employed 7,12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch carcinogenesis model juxtaposed with biochemical investigation of several detoxification and antioxidant markers, such as Cyt p450, Cyt b5, thiobarbituric acid reactive substance (TBARS), glutathione (GSH), glutathione reductase (GR), glutathione S transferase (GST), DT-diaphorase, vitamin C, vitamin E, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). The immunohistochemical assessment of cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), proliferating cell nuclear antigen (PCNA), and cyclin D1 expression were also performed to observe the effect of yohimbine on these markers. The hamsters treated with DMBA presented the growth of tumors in the buccal pouches, accompanied by significant changes in the liver and buccal mucosa levels of Phase I &amp; II detoxification enzymes and lipid peroxidation (LPO). A significant rise in the range of 2- to 3.5-fold was observed in Cyt p450, Cyt b5, and LPO in DMBA-treated animals. However, oral administration of yohimbine significantly restored the LPO, antioxidant, and detoxifying enzyme activities. Additionally, the levels of COX-2, IL-6, PCNA, and cyclin D1 were also found to be downregulated by yohimbine treatment. In conclusion, yohimbine improved the biochemical and immunohistochemical markers of DMBA-induced oral cancer and reverted to near normal values via ameliorating the underlying inflammation and oxidative stress conditions. Our study highlighted the potential of yohimbine as anticancer agent, especially against oral cancer and suggested its possible use as repurposed drug.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The buccal pouch of golden Syrian hamsters was painted with 0.5% DMBA in liquid paraffin three times a week for 14 weeks, ultimately leading to the development of oral squamous cell carcinoma (OSCC). Oral administration of PLGA-NDP (preinitiation) and Cisplatin delivery (5 mg/kg b.wt) started 1 week before the carcinogen exposure and continued on alternative days. Post-administration of PLGA-NDP (5 mg/kg b.wt) started 2 days after carcinogen (DMBA) induction until the end of the experiment. After the 14th week, we observed that DMBA-painted hamsters exhibited tumor formation, morphological alterations, and well-differentiated OSSC in addition to the responsive molecular proteins during oral carcinogenesis. Furthermore, immunoblotting analysis demonstrated that PLGA-NDP inhibits Notch signaling, as evidenced by downregulation of Bcl-Xl, Bcl-2, p21, PGE2, HGF, and CXCL12 proteins, and upregulation of p53 and Bax. This apoptotic response is crucial for PLGA-NDP to induce apoptosis. In addition, RT-PCR results showed that PLGA-NDP nanoparticles play a downregulatory role in the therapeutic action of the notch signaling gene (Notch1, Notch 2, Hes1, Hey1, and Jagged1) at the mRNA transcription level in HBP carcinoma. Taken together, these data indicate that PLGA-NDP is a potent inhibitor of oral carcinogenesis and the expansion of cells that specifically target the Notch signaling pathway indicates that obstructing Notch signaling could potentially serve as a new and innovative therapeutic approach for oral squamous cell carcinoma (OSCC).</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142399503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ebselen (Ebs), a synthetic organoselenium compound, affects cellular redox status in cancer cells. In the study, we observed that Ebs disrupted cellular redox balance and sensitized drug-resistant cells to doxorubicin (DOX) treatment. The combination of Ebs and DOX led to increased intracellular reactive oxygen species (ROS) levels and lipid peroxidation while decreasing the activity of thioredoxin reductase (TrxR) and cellular antioxidants in drug-resistant cells. Furthermore, this combination treatment demonstrated notable chemosensitizing effects by reducing cell viability and proliferation in MDR cells compared to DOX treatment alone. Additionally, the combination of Ebs and DOX induced DNA fragmentation and exhibited G2/M phase cell cycle arrest. Immunofluorescent analysis revealed that the Ebs and DOX combination upregulated the expression of p53 and p21, which activated the mitochondrial-dependent apoptotic pathway. The combination treatment also enhanced the upregulation of proapoptotic markers such as Bax, Caspase-3, -9, and cytochrome C, while downregulating the expression of the antiapoptotic marker Bcl-2. Therefore, the current discoveries suggest that Ebs could be employed as a drug candidate for reversing MDR in cancer cells by regulating cellular redox homeostasis.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142388329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their diversity reflects an organism's adaptation to physiological conditions and plays a complex function in cellular metabolism. Mitochondrial heterogeneity exists at the single-cell and tissue levels, impacting cell shape, size, membrane potential, and function. This heterogeneity can contribute to the progression of diseases such as neurodegenerative diseases, metabolic diseases, and cancer. Mitochondrial dynamics enhance the stability of cells and sufficient energy requirement, but these activities are not universal and can lead to uneven mitochondria, resulting in heterogeneity. Factors such as genetics, environmental compounds, and signaling pathways are found to affect these cellular processes and heterogeneity.

Its development is linked to multiple risk factors, such as alcohol and tobacco consumption, human papillomavirus (HPV) infection, and Epstein-Barr Virus (EBV) infection. Biochanin A (BCA), a phytoestrogen extracted from red clover, has been extensively researched for its therapeutic properties. It spans antioxidant activity, anti-inflammatory effects, neuroprotection, cardioprotection, and anticancer potential in different bodily systems. However, its impact on oral cancer remains unexplored. Therefore, this investigation aims to assess the potential anticancer effects of BCA, specifically on KB oral cancer cells. This study utilized KB cells to evaluate the impact of BCA on various cellular parameters, including cell viability, apoptosis, intracellular ROS production, mitochondrial membrane potential, and cell migration. BCA treatment induced several notable effects on KB cells, including reduced cell viability, altered morphology suggestive of apoptosis, heightened oxidative stress, and alterations in mitochondrial membrane potential. Moreover, BCA treatment demonstrated an inhibitory effect on cell migration. The study further investigated the impact of BCA on antioxidant enzyme activities and lipid peroxidation, revealing decreased antioxidant enzyme activities and increased lipid peroxidation across different BCA concentrations (IC₅₀ and IC₉₀). Immunocytochemistry and qRT-PCR analyses unveiled that BCA treatment at varying doses (IC₅₀ and IC₉₀) downregulated the expression of nuclear factor-κB (NF-κB) subunits p50 and p65, pivotal players in cancer progression. In summary, this study sheds light on the promising potential of BCA as an anticancer therapeutic agent for treating oral cancer. Its demonstrated ability to induce apoptosis, perturb cellular functions, and modulate gene expression within cancer cells underscores its significance. Nonetheless, further research, particularly following animal studies, is imperative to comprehensively grasp the breadth of BCA's effects and its viability for clinical applications.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142371060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
