    Aneuploidy: An opportunity within single-cell RNA sequencing analysis

    JOE R. DELANEY*

    BIOCELL, Vol.45, No.5, pp. 1167-1170, 2021, DOI:10.32604/biocell.2021.017296

    Abstract Single-cell sequencing data has transformed the understanding of biological heterogeneity. While many flavors of single-cell sequencing have been developed, single-cell RNA sequencing (scRNA-seq) is currently the most prolific form in published literature. Bioinformatic analysis of differential biology within the population of cells studied relies on inferences and grouping of cells due to the spotty nature of data within individual cell scRNA-seq gene counts. One biologically relevant variable is readily inferred from scRNA-seq gene count tables regardless of individual gene representation within single cells: aneuploidy. Since hundreds of genes are present on chromosome arms, high-quality inferences of aneuploidy can be made… More >

    The bacteriophage mu lysis system–A new mechanism of host lysis?

    SAIKAT SAMANTA1,#, ASHISH RANJAN SHARMA2,#, ABINIT SAHA1, MANOJ KUMAR SINGH1, ARPITA DAS1, MANOJIT BHATTACHARYA3, RUDRA PRASAD SAHA1,*, SANG-SOO LEE2,*, CHIRANJIB CHAKRABORTY1,*

    BIOCELL, Vol.45, No.5, pp. 1175-1186, 2021, DOI:10.32604/biocell.2021.015537

    Abstract Bacteriophages are viruses that infect bacteria and can choose any one of the two alternative pathways for infection, i.e., lysis or lysogeny. Phage lysis is one of the conventional biological processes required to spread infection from one bacterium to another. Our analysis suggests that in the paradigm bacteriophage Mu, six proteins might be involved in host cell lysis. Mu has a broad host range, and Mu-like phages were found in both Gram-negative and Gram-positive bacteria. An analysis of the genomes of Mu and Mu-like phages could be useful in elucidating the lysis mechanism in this group of phages. A detailed… More >

    Biomedical overview of melanin. 1. Updating melanin biology and chemistry, physico-chemical properties, melanoma tumors, and photothermal therapy

    ALFONSO BLÁZQUEZ-CASTRO1,2,*, JUAN CARLOS STOCKERT2,3

    BIOCELL, Vol.45, No.4, pp. 849-862, 2021, DOI:10.32604/biocell.2021.015900

    Abstract Melanins (eumelanin, pheomelanin, and allomelanin) represent a very, if not the most, important group of biological pigments. Their biological roles are multiple, from photoprotection to antioxidant activity, heavy metal disposal or the myriad uses of color in organisms across all Phyla. In the first part of this review, eumelanin biology and some chemical aspects will be presented, as well as key physico-chemical features that make this biological pigment so interesting. The principal characteristics of the melanocyte, the melanin-synthesizing cell in mammals, will also be introduced. Transformed melanocytes are the cause of one of the most devastating known cancers: the malignant… More >

    Hellebrigenin induces apoptosis in colorectal cancer Cells through induction of excessive reactive oxygen species

    BIOCELL, Vol.45, No.4, pp. 943-951, 2021, DOI:10.32604/biocell.2021.015836

    Abstract Traditional Chinese medicine (TCM) has been increasingly applied in both preventing and treating a variety of cancers in the last decades, attributing to its fewer side effects as compared with chemotherapy drugs. Hellebrigenin, a component of Chanpi from the skin of Bufo bufogargarizans Cantor or Duttaphrynus melanostictus has been reported to have an obvious anti-cancer activity on various cancers. However, the effect and mechanism of hellebrigenin on colorectal cancers were still unknown. Herein, the present study demonstrated hellebrigenin significantly reduced viability and triggered apoptosis via the intrinsic pathway in colorectal cancer cell lines HCT116 and HT29 in vitro and in… More >

    Incidence, genomic diversity, and evolution of strawberry mottle virus in China

    LINGJIAO FAN, CHENGYONG HE, MENGMENG WU, DEHANG GAO, ZHENFEI DONG, SHENGFAN HOU, ZEKUN FENG, HONGQING WANG*

    BIOCELL, Vol.45, No.4, pp. 1137-1151, 2021, DOI:10.32604/biocell.2021.015396

    Abstract Strawberry mottle virus (SMoV) is one of the most common viruses infecting strawberries, causing losses to fruit yield and quality. In this study, 165 strawberry leaf samples were collected from six provinces of China, 46 of which tested positive for SMoV. The complete genome sequences of 11 SMoV isolates were obtained from Liaoning (DGHY3, DGHY16-2, DGHY17, DGHY20-2, DGHY21, DGHY26-2), Shandong (SDHY1, SDHY5, SDHY31-2, SDHY33-2), and Beijing (BJMX7). The RNA1 and RNA2 nucleotide identities between the 11 Chinese isolates were 95.4–99.3% and 96.3–99.6%, respectively, and they shared 78.4–96.6% and 84.8–93.5% identities with the available SMoV isolates in GenBank. Recombination analysis revealed… More >

    BIOCELL, Vol.45, No.4, pp. 1081-1093, 2021, DOI:10.32604/biocell.2021.015363

    Abstract Nanotechnology has greatly expanded the applications of nanoparticles (NPs) domain in the scientific field. In this context, the zinc oxide nanoparticles (ZnO-NPs) and 24-epibrassinolide (EBL) has been revealed to positively regulate plant metabolism and growth. In the present study, we investigated the role of ZnO-NPs and EBL in the regulation of plant growth, photosynthetic efficiency, enzymes activities and fruit yield in tomato. Foliar treatment of ZnO-NPs at three levels (10, 50 or 100 ppm) and EBL (10−8 M) were applied separately or in combination to the foliage of plant at 35–39 days after sowing (DAS); and the control plants were… More >

    Oxidative metabolism of photosynthetic species and the exposure to some freshwater and marine biotoxins

    SUSANA PUNTARULO1,2, PAULA MARIELA GONZÁLEZ1,2,*

    BIOCELL, Vol.45, No.4, pp. 813-821, 2021, DOI:10.32604/biocell.2021.015360

    Abstract Environmental climate conditions could lead to an increasing global occurrence of microorganism blooms that synthesize toxins in the aquatic environments. These blooms could result in significantly toxic events. Responses of photosynthetic organisms to adverse environmental conditions implicate reactive oxygen species generation; but, due to the presence of a varied cellular antioxidant defense system and complex signaling networks, this oxidative stress could act as an important factor in the environmental adaptive processes. The objective of this review was to assess how some biotoxins are implicated in the generation of oxidative and nitrosative metabolic changes, not only in biotoxin-producing organisms but also… More >

    Microfluidic chips for the endothelial biomechanics and mechanobiology of the vascular system

    HAORAN SU1, KEXIN LI1, XIAO LIU1,*, JING DU1, LI WANG4, XIAOYAN DENG3,*, YUBO FAN1,2,*

    BIOCELL, Vol.45, No.4, pp. 797-811, 2021, DOI:10.32604/biocell.2021.014900

    Abstract Endothelial cells arranged on the vessel lumen are constantly stimulated by blood flow, blood pressure and pressureinduced cyclic stretch. These stimuli are sensed through mechanical sensory structures and converted into a series of functional responses through mechanotransduction pathways. The process will eventually affect vascular health. Therefore, there has been an urgent need to establish in vitro endothelial biomechanics and mechanobiology of models, which reproduce three-dimensional structure vascular system. In recent years, the rapid development in microfluidic technology makes it possible to replicate the key structural and functionally biomechanical characteristics of vessels. Here, we summarized the progress of microfluidic chips used… More >
