    An Innovative Bispectral Deep Learning Method for Protein Family Classification

    Isam Abu-Qasmieh, Amjed Al Fahoum*, Hiam Alquran, Ala’a Zyout

    CMC-Computers, Materials & Continua, Vol.75, No.2, pp. 3971-3991, 2023, DOI:10.32604/cmc.2023.037431

    Abstract Proteins are essential for many biological functions. For example, folding amino acid chains reveals their functionalities by maintaining tissue structure, physiology, and homeostasis. Note that quantifiable protein characteristics are vital for improving therapies and precision medicine. The automatic inference of a protein’s properties from its amino acid sequence is called “basic structure”. Nevertheless, it remains a critical unsolved challenge in bioinformatics, although with recent technological advances and the investigation of protein sequence data. Inferring protein function from amino acid sequences is crucial in biology. This study considers using raw sequencing to explain biological facts using a large corpus of protein… More >

    Genome-Wide Identification and Characterisation of Abiotic Stress Responsive mTERF Gene Family in Amaranthus hypochondriacus

    Mortaza Hajyzadeh*

    Phyton-International Journal of Experimental Botany, Vol.92, No.5, pp. 1649-1664, 2023, DOI:10.32604/phyton.2023.028028

    Abstract Abiotic stresses at different growth stages in the life of plants negatively affect yield productivity. Therefore, plants, including Amaranthus hypochondriacus, develop adaptive strategies to face the stresses and expand functional diversification. In plants, the mitochondrial transcription termination factors (mTERF) are essential functions in regulation, and organelles (mitochondria and chloroplasts) control gene expression (OGE) under several stress conditions. Based on the in-silico-wide genome and transcriptome analysis, twenty-four mTERF genes were detected in the main targeted mitochondria organelles clustered into three different main groups. The chromosomal location and gene duplication analysis indicated one segmental and one tandem duplication in the genome. The… More >

    Intracellular life of protozoan Toxoplasma gondii: Parasitophorous vacuole establishment and survival strategies

    JULIANA A. PORTES1, ROSSIANE C. VOMMARO1, LUCIO AYRES CALDAS2, ERICA S. MARTINS-DUARTE3,*

    BIOCELL, Vol.47, No.4, pp. 929-950, 2023, DOI:10.32604/biocell.2023.026629

    Abstract Toxoplasma gondii is a protozoan of worldwide distribution and the agent of toxoplasmosis. It is estimated that 30%–50% of the world population could be infected with this parasite. Although the infection in immunocompetent individuals is mostly asymptomatic, the disease in immunosuppressed and pregnant is a risk condition. As a member of the phylum Apicomplexa, T. gondii has an obligatory intracellular lifestyle; therefore, invading a host cell and establishing it inside a parasitophorous vacuole (PV) are mandatories for the survival of this parasite. The construction of a perfect intracellular niche for T. gondii requires the secretion of an arsenal of proteins… More >

    Oncology Research, Vol.31, No.1, pp. 71-82, 2023, DOI:10.32604/or.2022.028075

    Abstract Cutaneous squamous cell carcinoma (cSCC), a type of non-melanoma skin cancer (NMSC), is the most common malignancy worldwide. Thioredoxin (TXN) domain-containing protein 9 (TXNDC9) is a member of the TXN family that is important in cell differentiation. However, the biological function of this protein in cancer, particularly cSCC, is still unknown. In the present study, our experiments revealed the protective effects of TXNDC9 on UV-B-irritated cSCC cells. The initial findings showed that TXNDC9 is significantly upregulated in cSCC tissue and cells compared to normal skin tissue and keratinocytes. UV-B radiation robustly induces the expression of TXNDC9, and UV-B-induced cSCC cell… More >

    Changes of protein expression during tumorosphere formation of small cell lung cancer circulating tumor cells

    SANDRA STICKLER1, BARBARA RATH1, MAXIMILIAN HOCHMAIR2, CLEMENS LANG3, LUKAS WEIGL4, GERHARD HAMILTON1,*

    Oncology Research, Vol.31, No.1, pp. 13-22, 2023, DOI:10.32604/or.2022.027281

    Abstract Small cell lung cancer (SCLC) is frequently disseminated and has a dismal prognosis with survival times of approximately two years. This cancer responds well to initial chemotherapy but recurs within a short time as a globally chemoresistant tumor. Circulating tumor cells (CTCs) are held responsible for metastasis, the extremely high numbers of these cells in advanced SCLC allowed us to establish several permanent CTC cell lines. These CTCs are distinguished by the spontaneous formation of large spheroids, termed tumorospheres, in regular tissue culture. These contain quiescent and hypoxic cells in their interior and are associated with high chemoresistance compared to… More >

    FANBIAO KONG1,2,#, KUN WU3,4,#, LIMING PANG2,#, YULIANG HUANG2,#, LEI LI3, JING XU2, FEITONG LI2, YAN QING2, ZHONGYU WANG2, XIURONG HUANG3, SHENG XU2, XIAOGANG ZHONG2, ZHOU ZHU2, XIAOTONG WANG3,*, JIANRONG YANG5,*

    Oncology Research, Vol.30, No.6, pp. 277-288, 2022, DOI:10.32604/or.2022.027301

    Abstract Introduction: Siva-1, as a pro-apoptotic protein, has been shown to induce extensive apoptosis in a number of different cell lines. In our previous study, we showed that overexpressed Siva-1 decreased the apoptosis of gastric cancer cells. So, we believe that it can also work as an anti-apoptotic protein. The present study aimed to determine the specific role of Siva-1 in anticancer drug resistance in gastric cancer in vivo and in vitro and preliminarily reveal the mechanism. Materials and Methods: A vincristine-resistant MKN-28/VCR gastric cancer cell line with stably downregulated Siva-1 was established. The effect of Siva-1 downregulation on chemotherapeutic drug… More >

    Lack of Tocopherol Inhibits Rice Growth by Triggering an Ectopic Stress Response and the Accumulation of DELLA Protein

    Di Wang1,#,*, Hao Gao1,#, Jian Wang1, Baoshan Cheng1, Gang Li1, Weijun Xu1, Xi Liu2,3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1173-1183, 2023, DOI:10.32604/phyton.2023.026526

    Abstract Although tocopherols are essential for rice development, the molecular details by which their absence affects development remain to be determined. To study how tocopherols function during rice development, we performed a transcriptome deep sequencing (RNA-seq) analysis of the rice cultivar Nipponbare (Nip) and the tocopherol-deficient mutant small grain and dwarf 1-2 (sgd1-2). We identified 563 differentially expressed genes that were enriched in Gene Ontology categories associated with metabolism, stress, cellular responses, and transcriptional regulation. We determined that the total fatty acid composition of Nip and sgd1-2 was comparable, although cell membrane penetrability in sgd1-2 was significantly higher than in Nip… More >

    Maria Babar1, Siddra Ijaz1,*, Imran Ul Haq2, Muhammad Sarwar Khan1

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1289-1300, 2023, DOI:10.32604/phyton.2023.026469

    Abstract We developed a molecular marker for MAS of mungbean resistant varieties against CLS from the consensus sequence (MB-CLsRG) of identified RGAs (MB-ClsRCaG1 and MB-ClsRCaG2). The MB-CLsRG sequence-specific primer pair was used to screen Cercospora leaf spot (CLS) resistant varieties of mungbean in genomic analysis that showed congruency with phenotypic screening. Validation of molecular marker linkage with CLS resistance was performed using rtPCR in transcriptomic analysis. The sequenced PCR products showed 100% homology with MB-CLsRG sequence and putative disease resistance proteins that confirmed the linkage of molecular marker with CLS resistance in mungbean. The antifungal potential of MB-CLsRG gene encoding protein… More >

    Light Promotes Protein Stability of Auxin Response Factor 7

    Shucai Wang*

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1153-1160, 2023, DOI:10.32604/phyton.2023.026355

    Abstract Light is an environmental signaling, whereas Aux/IAA proteins and Auxin Response Factors (ARFs) are regulators of auxin signalling. Aux/IAA proteins are unstable, and their degradation dependents on 26S ubiquitin-proteasome and is promoted by Auxin. Auxin binds directly to a SCF-type ubiquitin-protein ligase, TIR1, facilitates the interaction between Aux/IAA proteins and TIR1, and then the degradation of Aux/IAA proteins. A few studies have reported that some ARFs are also unstable proteins, and their degradation is also mediated by 26S proteasome. In this study, by using of antibodies recognizing endogenous ARF7 proteins, we found that protein stability of ARF7 was affected by… More >
