Objective: Coronavirus Disease 2019 (COVID19) is a viral disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS CoV-2). The high mutation propensity of the SARS CoV-2 genome is one of the biggest threats to the long-term validity of treatment options. Helicases are anti-viral targets because of the vital role they play in the viral life cycle. In this study, changes in the protein structure caused by SARS CoV-2 nsp13 mutations were investigated to contribute to the development of effective antiviral drugs. Materials and Methods: Genome data of 298 individuals located in the China location were examined. The mutant model was built using deep learning algorithms. Model quality assessment was done with QMEAN. Protein stability analyses were performed with DynaMut2 and Cutoff Scanning Matrix stability. Changes in substrate affinity were performed with Haddock v2.4. Results: In this study, twenty-eight mutations in nsp13 were identified (23 sense, 5 missense). The changes in protein structure caused by the five missense mutations (Leu14Phe, Arg15Ser, Arg21Ser, Leu235Phe, Ala454Thr) were modeled. The mutations caused a decrease in the stability of SARS CoV-2 helicase (-0.99, -1.66, -1.15, -0.54, and -0.73 for Leu14Phe, Arg15Ser, Arg21Ser, Leu235Phe, Ala454Thr, respectively). The mutations reduced the helicase's affinity to the substrate. The docking scores for wild-type and mutant helicase were -84.4±1.4 kcal.mol-1 and -71.1±6.7 kcal.mol-1, respectively. Conclusion: Helicase mutations caused a decrease in the protein stability and nucleic acid affinity of the SARS CoV-2 helicase. The results provide important data on the development of potential antivirals and the effect of mutation on the functions of viral proteins. © European Journal of Biology.All rights reserved.
目的:冠状病毒病2019 (covid - 19)是由严重急性呼吸综合征冠状病毒-2 (SARS - CoV-2)引起的病毒性疾病。SARS冠状病毒-2基因组的高突变倾向是对治疗方案长期有效性的最大威胁之一。解旋酶是抗病毒靶标,因为它们在病毒生命周期中起着至关重要的作用。在本研究中,研究了SARS CoV-2 nsp13突变引起的蛋白质结构变化,以促进有效抗病毒药物的开发。材料与方法:对中国地区298例个体的基因组数据进行分析。利用深度学习算法建立突变体模型。采用QMEAN进行模型质量评价。用DynaMut2和cut - off扫描矩阵稳定性分析蛋白质稳定性。利用Haddock v2.4进行底物亲和力的改变。结果:本研究共检测到28个nsp13基因突变(23个正确,5个错义)。模拟5个错义突变(Leu14Phe、Arg15Ser、Arg21Ser、Leu235Phe、Ala454Thr)引起的蛋白结构变化。突变导致SARS CoV-2解旋酶的稳定性下降(Leu14Phe、Arg15Ser、Arg21Ser、Leu235Phe、Ala454Thr分别为-0.99、-1.66、-1.15、-0.54和-0.73)。突变降低了解旋酶对底物的亲和力。野生型和突变型解旋酶的对接得分分别为-84.4±1.4 kcal.mol-1和-71.1±6.7 kcal.mol-1。结论:解旋酶突变导致SARS CoV-2解旋酶蛋白稳定性和核酸亲和力下降。这些结果为开发潜在的抗病毒药物以及突变对病毒蛋白功能的影响提供了重要的数据。©欧洲生物学杂志。版权所有。

Objective: Salvia absconditiflora Greuter & Burdet is an endemic plant and survives in nature by adapting to extreme conditions. The aims of this study are to characterize and compare the diversity in the spectral-chemical structure of S. absconditiflora’s plant parts using the FTIR spectroscopy technique, to determine the wettability of the adaxial and abaxial epidermal surfaces of S. abscontidiflora leaves and to interpret whether there is a difference between the contact angle (CA) measurements at the points determined in the surface area of the leaves from the part close to the petiole to the leaf tip. Materials and Methods: The ATR-FTIR spectra for the chemical content of S. absconditiflora were obtained from six different plant parts and information about their chemical compositions was obtained. CA measurements were carried out for the natural events of the leaf area, especially for the water holding capacity or hydrophilic-hydrophobic characteristics. Results: The biochemical fingerprint of S. absconditiflora was determined by the analysis of chemical groups in vegetative and generative plant parts using ATR-FTIR spectroscopy. The CAs showed that the leaf had a hydrophobic character. In addition, leaf hysteresis was determined for each plant part, and it was understood that the lotus effect also appeared in S. absconditiflora. Conclusion: Detailed biochemical profiling, wettability, and hysteresis reports of S. absconditiflora were created for the first time. With this study, important clues about the adaptation of plants to harsh conditions were obtained.

Exploring host-HTLV-1 interactions and the molecular processes underpinning HTLV-1-mediated carcinogenesis is crucial for establishing effective treatments for viral infection and associated leukemia/lymphoma. Several HTLV-1 proteins have been shown to play important roles in the cellular transformation and immortalization of infected T cells. Through interactions with MAVS, STING, and RIP1, the HTLV-1 oncoprotein Tax suppresses the innate IFN response, resulting in the inhibition of TBK1-mediated phosphorylation of IRF3/IRF7. The HTLV-1 protein HBZ affects genomic integrity and inhibits target cell death and autophagy. Furthermore, it has been discovered that HBZ promotes the growth of ATL cells and aids in the evasion of infected cells from immunosurveillance. It currently appears that the efficacy of an individual's cytotoxic T cell (CTL) response to HTLV-1 is the most important single predictor of that person's provirus load, which can differ by more than 10,000-fold amongst HTLV-1-infected persons. We examine recent improvements in our knowledge of the pathophysiology, or underlying processes, of the illness produced by HTLV-1 infection in this article. Furthermore, we explore the future approach for targeting HTLV-1-associated malignancies and anti-HTLV-1 therapies. The pathogenic agent of adult T-cell leukemia/lymphoma (ATL) is human T-cell lymphotropic virus type 1 (HTLV-1). ATL is a fast-developing clonal tumour of CD4+ T cells which are cellular and viral protein interactions and pave the way for the discovery of new classes of cellular modulators, which may induce Tax oncogenesis and its impact on survival signalling pathways such as the NF-B and PI3K-Akt pathways, therapeutic target opportunities for ATL have been presented in two collaborative studies.
探索宿主- htlv -1相互作用和htlv -1介导癌变的分子过程对于建立病毒感染和相关白血病/淋巴瘤的有效治疗方法至关重要。一些HTLV-1蛋白已被证明在感染T细胞的细胞转化和永生化中发挥重要作用。HTLV-1癌蛋白Tax通过与MAVS、STING和RIP1相互作用,抑制先天IFN应答,从而抑制tbk1介导的IRF3/IRF7磷酸化。HTLV-1蛋白HBZ影响基因组完整性并抑制靶细胞死亡和自噬。此外,已经发现HBZ促进ATL细胞的生长,并帮助感染细胞逃避免疫监视。目前看来,一个人的细胞毒性T细胞(CTL)对HTLV-1的反应的效力是该人的原病毒载量的最重要的单一预测指标,在HTLV-1感染者中,其差异可能超过10,000倍。在本文中,我们研究了HTLV-1感染引起的疾病的病理生理学或潜在过程的最新进展。此外,我们还探索了靶向htlv -1相关恶性肿瘤和抗htlv -1治疗的未来方法。成人t细胞白血病/淋巴瘤(ATL)的病原是人t细胞嗜淋巴病毒1型(HTLV-1)。ATL是一种快速发展的CD4+ T细胞克隆肿瘤,细胞和病毒蛋白相互作用,为发现新的细胞调节剂铺平了道路,这些调节剂可能诱导肿瘤的发生及其对NF-B和PI3K-Akt通路等生存信号通路的影响,两项合作研究已经提出了ATL的治疗靶点机会。

Objective: Polygonatum (Asparagaceae) is a rhizomatous monocotyledon genus that is distributed in the temperate regions of the Northern Hemisphere. The genus is represented by 5 species in Turkey (P. glaberrimum, P. latifolium, P. multiflorum, P. verticillatum and P. orientale). Karyological, palynological, phylogenic, chemotaxonomical and some anatomical studies of Polygonatum species have been carried out previously. However, the detailed anatomical features of the scape, rhizome and root of Polygonatum species grown in Turkey have not been examined before and so the aim of this study is to determine their anatomical characteristics. Also, the study compares the species with each other according to obtained anatomical characteristics and comparing them with previous anatomical studies. Materials and Methods: Investigations were carried out on fresh material collected from wild habitats during July 20092012 in Turkey. Cross-sections of scape, rhizome and roots were cut by hand, detailed photographs were taken under a light microscope, and anatomical structures were drawn in detail with an isograph pen. Results: The anatomical structures of Polygonatum species have monocotyledones features. Significant differences between species were observed, such as the number of costas in the scape, number of xylem arms in the root and the types of vascular bundle in the rhizome. Also, the anatomical characteristics of the species were compared with previous anatomical studies. Conclusion: The anatomical features determined by this study will be useful at the species level as well as at the genus and family level. Hence the obtained data will contribute to the literature.
