    TARYN E. SYMON1, RAMÓN GAXIOLA-ROBLES1,2, CLAUDIA J. HERNÁNDEZ-CAMACHO3, TANIA ZENTENO-SAVÍN1,*

    BIOCELL, Vol.45, No.6, pp. 1621-1630, 2021, DOI:10.32604/biocell.2021.016302

    Abstract Marine mammals undergo cycles of tissue ischemia and reperfusion during the dive response. Reperfusion injury can result in oxidative tissue damage and the activation of a pro-inflammatory immune response. The risk of oxidative damage is reduced by antioxidants. Our hypothesis is that the reported higher antioxidant defenses within marine mammal tissues provide additional protection in situations that produce oxidative stress, like inflammation, in comparison to terrestrial mammal tissues. Leukocytes were isolated from the whole blood of Pacific bottlenose dolphins (Tursiops truncatus gilli) and humans (Homo sapiens) and were exposed to lipopolysaccharides (LPS, 10 µg/mL) in vitro to simulate a pro-inflammatory… More >

    YASSER S. MOSTAFA1,*, SAAD A. ALAMRI1,2, SULIMAN A. ALRUMMAN1, TAREK H. TAHA3, MOHAMED HASHEM1,4, MAHMOUD MOUSTAFA1,5, LAMIAA I. FAHMY6

    BIOCELL, Vol.45, No.6, pp. 1661-1672, 2021, DOI:10.32604/biocell.2021.016193

    Abstract The study was sought to enhance the synthesis of thermal stable β-cyclodextrin glycosyltransferase (β-CGTase) using potato wastewater as a low-cost medium and assess the degree to which it is efficient for industrial production of β-cyclodextrin (β-CD) from raw potato starch. Thermophilic bacteria producing β-CGTase was isolated from Saudi Arabia and the promising strain was identified as Bacillus licheniformis using phylogenetic analysis of the 16S rRNA gene. Alginate-encapsulated cultures exhibited twice-fold of β-CGTase production more than free cells. Scanning electron microscopy (SEM) of polymeric capsules indicated the potential for a longer shelf-life, which promotes the restoration of activity in bacterial cells… More >

    LEI JIANG1,2,3,#, SHUAI LI1,#, XIZI JIANG1, TONG JIANG1,2,3,*

    BIOCELL, Vol.45, No.6, pp. 1695-1702, 2021, DOI:10.32604/biocell.2021.015250

    Abstract It was rarely reported about strawberry vein banding virus (SVBV) genome sequence in China and most countries worldwide. In this work, we determined the complete genome sequences of two SVBV isolates in China, designated SVBV-AH and SVBV-BJ, that were obtained from naturally infected strawberry samples from Anhui province and Beijing city of China, respectively. The complete genomes of SVBV-AH and SVBV-BJ were 7,862 nucleotides (nts) and 7,863 nts long, respectively, and both constituted with seven genes typical of the caulimoviruses. Alignment of complete nucleotide sequences showed that SVBV-AH and SVBV-BJ shared a significant nucleotide sequence identity of 97.7% of each… More >

    RNA-sequencing indicates high hemocyanin expression as a key strategy for cold adaptation in the Antarctic amphipod Eusirus cf. giganteus clade g3

    SAMUELE GRECO1,#, ELISA D’AGOSTINO2,#, CHIARA MANFRIN1, ANASTASIA SERENA GAETANO1, GAEL FURLANIS1, FRANCESCA CAPANNI1, GIANFRANCO SANTOVITO2, PAOLO EDOMI1, PIERO GIULIO GIULIANINI1, MARCO GERDOL1,*

    BIOCELL, Vol.45, No.6, pp. 1611-1619, 2021, DOI:10.32604/biocell.2021.016121

    Abstract We here report the de novo transcriptome assembly and functional annotation of Eusirus cf. giganteus clade g3, providing the first database of expressed sequences from this giant Antarctic amphipod. RNA-sequencing, carried out on the whole body of a single juvenile individual likely undergoing molting, revealed the dominant expression of hemocyanins. The mRNAs encoding these oxygen-binding proteins cumulatively accounted for about 40% of the total transcriptional effort, highlighting the key biological importance of high hemocyanin production in this Antarctic amphipod species. We speculate that this observation may mirror a strategy previously described in Antarctic cephalopods, which compensates for the decreased ability… More >

    XINGYU MEI, ZHOUWEI WU, CHENGZHONG ZHANG, YUE SUN, WEIMIN SHI*

    BIOCELL, Vol.45, No.6, pp. 1551-1559, 2021, DOI:10.32604/biocell.2021.015376

    Abstract Vitiligo results in an autoimmune disorder destructing skin pigment cells, melanocytes (Mcs). This study aimed to investigate whether Astragaloside IV (AIV) could efficiently induce differentiation of bone marrow mesenchymal stem cells (BMMSCs) into Mcs. BMMSCs were induced and differentiated into Mcs with 0.1, 0.2, and 0.4 mg/L AIV during 150-day. Morphologic changes of differentiated cells were observed. Levels of some melanocytic specific genes (TRP-1, TRP-2, MART-1, Mitf) were measured with quantitative polymerase chain reaction (qPCR) at 90, 120, and 150 days of induction. After 90-day induction, the differentiated cells with 0.4 mg/L AIV demonstrated the typical morphology of Mcs, positive… More >

    BIOCELL, Vol.45, No.6, pp. 1501-1507, 2021, DOI:10.32604/biocell.2021.09528

    Abstract Spinal muscular atrophy (SMA) is an autosomal recessive hereditary neuromuscular disease. Exon 7 and 8 of survival of motor neuron 1 (SMN1) gene or only exon 7 homology deletion leads to the failure to produce a full-length SMN gene. The copy number of SMN2 gene with high homology of SMN1 affects the degree of disease and was the target gene for targeting therapy, in which splicing silencer in intron 7 was the key to suppress the inclusion of exon 7. In this study, we projected to use CRISPR/Case 9 for the targeted editing of intronic-splicing silencer (ISS) sequence to promote… More >

    KEWEI GAO1,#, JIANGFENG HU2,#, YI ZHOU3, LIANG ZHU1,*

    BIOCELL, Vol.45, No.6, pp. 1521-1526, 2021, DOI:10.32604/biocell.2021.09220

    Abstract Increasing evidence proves that circular RNAs (circRNAs) play an important role in regulating the biological behaviors of tumors. The central purpose of this research was to investigate the functions of circRNA in gastric cancer. The utilization of real-time PCR was to test circPTN expression in gastric cancer cells. Cell counting colony formation assays, CCK-8 assay, and EdU assay were used to investigate proliferation. Transwell assay was applied to investigate migration. We discovered that circPTN was highly expressed in gastric cancer cells. Low expression of circPTN inhibits gastric cancer cell proliferation and migration. Elevated expression of circPTN promotes gastric cancer cell… More >

    Implications of enolase in the RANKL-mediated osteoclast activity following spinal cord injury

    RAMSHA SHAMS1,2, NAREN L. BANIK1,2,3,*, AZIZUL HAQUE1,*

    BIOCELL, Vol.45, No.6, pp. 1453-1457, 2021, DOI:10.32604/biocell.2021.017659

    Abstract Spinal Cord Injury (SCI) is a debilitating condition characterized by damage to the spinal cord, resulting in loss of function, mobility, and sensation. Although increasingly prevalent in the US, no FDA-approved therapy exists due to the unfortunate complexity of the condition, and the difficulties of SCI may be furthered by the development of SCI-related complications, such as osteoporosis. SCI demonstrates two crucial stages for consideration: the primary stage and the secondary stage. While the primary stage is suggested to be immediate and irreversible, the secondary stage is proposed as a promising window of opportunity for therapeutic intervention. Enolase, a metabolic… More >

    Real-Time analysis of exosome secretion of single cells with single molecule imaging

    PENGFEI ZHANG1, SHAOPENG WANG1,2,*

    BIOCELL, Vol.45, No.6, pp. 1449-1451, 2021, DOI:10.32604/biocell.2021.017607

    Abstract The exosome-mediated response can promote or restrain the diseases by regulating the intracellular pathways, making the exosome become an effective marker for diagnosis and therapeutic control at the single-cell level. However, real-time analysis is hard to be achieved with traditional approaches because the exosomes usually need to be enriched by ultracentrifugation for a measurable signal-to-noise ratio. Recently developed label-free single-molecule imaging approaches may become an real-time quantitative tool for the analysis of single exosomes and related secretion behaviors of single living cells owing to their extreme sensitivity.
