    Emerging environmental stressors and oxidative pathways in marine organisms: Current knowledge on regulation mechanisms and functional effects

    MAURA BENEDETTI, MARIA ELISA GIULIANI, MARICA MEZZELANI, ALESSANDRO NARDI, LUCIA PITTURA, STEFANIA GORBI, FRANCESCO REGOLI

    BIOCELL, Vol.46, No.1, pp. 37-49, 2022, DOI:10.32604/biocell.2022.017507

    Abstract Oxidative stress is a critical condition derived from the imbalance between the generation of reactive oxygen species and the sophisticated network of antioxidant mechanisms. Several pollutants and environmental factors can affect this system through connected mechanisms, indirect relationships, and cascade effects from pre-transcriptional to catalytic level, by either enhancing intracellular ROS formation or impairing antioxidant defenses. This review summarizes the current knowledge on the pro-oxidant challenges from emerging environmental stressors threatening marine organisms, such as pharmaceuticals, microplastics and climate-related ocean changes. Emphasis will be placed on oxidative pathways, including signaling proteins and transcription factors involved in regulation of antioxidant responsiveness.… More >

    miR-153 as biomarker for cancer—functional role as tumor suppressor

    SALONI THAKUR1, ADESH K. SAINI2,3, JOYDEEP DAS4, VIPIN SAINI3, PARIN BALHARA5, JAGPREET S. NANDA6, REENA V. SAINI2,3

    BIOCELL, Vol.46, No.1, pp. 13-26, 2022, DOI:10.32604/biocell.2022.016953

    Abstract MicroRNA-153 (miR-153), belongs to a class of small non-coding RNA. It is a critical regulator of gene expression at the post-transcriptional level which interacts with the functional mRNA at 3’UTR region and suppresses the expression of the mRNA. More recently, it has become apparent that changes in the miR-153 expression lead to invasion, metastasis, angiogenesis and various types of tumor progression. This review summarizes the connection between dysregulation of miR-153 and various types of cancer progression. miR-153 regulates various signaling pathways to inhibit the proliferation and induce apoptosis in the cancer cell and also show synergistic activity with anticancer drugs.… More >

    BIOCELL, Vol.46, No.1, pp. 137-148, 2022, DOI:10.32604/biocell.2022.016807

    Abstract In this study, we investigated the protective effect of hyperbaric oxygen (HBO) on PC12 and H9C2 cell damage caused by oxygen-glucose deprivation/reperfusion and its possible mechanism. PC12 and H9C2 cell oxygen-glucose deprivation/reperfusion model were established. Cells were divided into a control group, model group, hyperbaric air (HBA) group and HBO group. The cell viability was detected by the CCK8 assay. Hoechst 33342 and PI staining assays and mitochondrial membrane potential (MMP) assays were used to detect cell apoptosis. The ultrastructure of cells, including autophagosomes, lysosomes, and apoptosis, were examined using a transmission electron microscope. The expression of autophagy-related proteins was… More >

    In Silico analysis and linking of metabolism-related genes with the immune landscape in head and neck squamous cell carcinoma

    JIAYU ZHANG1,2,3,#, RUOYAN CAO1,2,3,#, JIANMIN PENG1,2,3, QINCHAO HU1,2,3, JUAN XIA1,2,3,*, BIN CHENG1,2,3,*

    BIOCELL, Vol.46, No.1, pp. 111-125, 2022, DOI:10.32604/biocell.2022.016612

    Abstract Metabolic reprogramming and immunologic suppression are two critical characteristics promoting the progression of head and neck squamous cell carcinoma (HNSCC). The integrative analysis of all the metabolism-related genes (MRGs) in HNSCC is lacking and the interaction between the metabolism and the immune characteristics also requires more exploration to uncover the potential mechanisms. Therefore, this study was designed to establish a prognostic signature based on all the MRGs in HNSCC. Genes of HNSCC samples were available from the TCGA and GEO databases while the MRGs were retrieved from a previous study. Ultimately 4 prognostic MRGs were selected to construct a model… More >

    Ultrastructural analysis of sperm from the genus Idarnes (Hymenoptera: Chalcidoidea, Sycophaginae)

    KHESLLER PATRÍCIA OLAZIA1,2, JULIANA SOUZA DA SILVA1, GUILHERME SIRIMARCO DE SOUZA TONELLI1, SÔNIA NAIR BÁO1,*

    BIOCELL, Vol.46, No.1, pp. 275-283, 2022, DOI:10.32604/biocell.2022.016603

    Abstract In this study, the sperm ultrastructure of three species of Idarnes genus was investigated using light and transmission electron microscopy. Spermatozoon morphology of the three species was similar to that of most Chalcidoidea, with helicoidally twisted nucleus and flagellum. The head region consists of an acrosome and a nucleus; the nucleus-flagellum transition region characterized by the presence of mitochondrial derivatives and the centriolar adjunct; a flagellum region, which includes the axoneme with microtubular arrangement 9 + 9 + 2 and two mitochondrial derivatives. However, the sperm of these three species exhibit features that discriminate one species from each other: (1)… More >

    Transcriptome profile analysis of the accompanying migratory parasitic wasp Aenasius bambawalei (= Aenasius arizonensis girault) (Hymenoptera: Encyrtidae): Genes related to fertilization involved at different stage of ovary development

    JUAN ZHANG2, JUN HUANG3, YAYUAN TANG2, XIUZHEN LONG1

    BIOCELL, Vol.46, No.1, pp. 195-205, 2022, DOI:10.32604/biocell.2022.016563

    Abstract Age-related declines in fertilization success have been reported for a wide range of species. The fertilization of parasitic wasps is closely related to egg production and sperm storage. Aenasius bambawalei (Hymenoptera: Encyridae) is a key parasitic wasp of the important invasive mealybug Phenacoccus solenopsis (Hemiptera: Pseudococcidae). The female offspring ratio of this parasitic wasp was declined with parental age in mass rearing under laboratory conditions. To investigate the molecular mechanisms involved in the reproduction of A. bambawalei, an extensive analysis of the impact of age on transcriptome profile of mated ovaries of this wasp was performed by comparing the gene… More >

    Proteome-wide screening for the analysis of protein targeting of Chlamydia pneumoniae in endoplasmic reticulum of host cells and their possible implication in lung cancer development

    YANYAN LI1, SHAHANAVAJ KHAN2,3,4, ANIS AHMAD CHAUDHARY5, HASSAN AHMED RUDAYNI5, ABDUL MALIK2, ASHWAG SHAMI6

    BIOCELL, Vol.46, No.1, pp. 87-95, 2022, DOI:10.32604/biocell.2022.016509

    Abstract Available reports have confirmed a link between bacterial infection and the progression of different types of cancers, including colon, lungs, and prostate cancer. Here we report the Chlamydia pneumonia proteins targeting in endoplasmic reticulum (ER) using in-silico approaches and their possible role in lung cancer etiology. We predicted 48 proteins that target human ER, which may be associated with protein folding and protein-protein interactions during infection. The results showed C. pneumoniae proteins targeting human ER and their implications in lung cancer growth. These targeted proteins may be involved in competitive interactions between host and bacterial proteins, which may change the… More >

    Dengue virus infection: A review of advances in the emerging rapid detection methods

    MUBASHIR HUSSAIN1, ZEESHAN ALI1, BIN LIU2, JIANGUO DAI1, XIAOLONG LIU1, JUNCHEN ZHU1, YONGJUN TANG1

    BIOCELL, Vol.46, No.1, pp. 61-74, 2022, DOI:10.32604/biocell.2022.016392

    Abstract Dengue virus infections are increasing worldwide generally and in Asia, Central and South America and Africa, particularly. It poses a serious threat to the children population. The rapid and accurate diagnostic systems are essentially required due to lack of effective vaccine against dengue virus and the progressive spread of the dengue virus infection. The recent progress in developing micro- and nano-fabrication techniques has led to low cost and scale down the biomedical point-of-care devices. Starting from the conventional and modern available methods for the diagnosis of dengue infection, this review examines several emerging rapid and point-of-care diagnostic devices that hold… More >

    An active RUNX1-ID1/ID3 axis governs differentiation and chemoresistance of cancer stem cell population in epithelial ovarian cancer cells

    AJIT C. DHADVE1,2, PRITHA RAY1,2

    BIOCELL, Vol.46, No.1, pp. 75-86, 2022, DOI:10.32604/biocell.2022.016346

    Abstract Progression, relapse, and therapy resistance are the most challenging features of cancer therapy that have been postulated to be driven by Cancer Stem Cell (CSC) population. This enigmatic subpopulation of cancer cells has therefore emerged as promising therapeutic candidate. We earlier reported enrichment of CSC-like side population (SP) with increasing resistance towards Cisplatin and Paclitaxel either alone or in combination in epithelial ovarian cancer (EOC) cells. This SP population is a small proportion of the total population of cancer cells characterised with high expression of drug transporters, a unique feature of stem cells and thereby can be isolated through their… More >

    LINGJIAO FAN1, DAN SONG1, YINGWEI KHOO2, MENGMENG WU1, TENGFEI XU1, XIAOLI ZHAO1, HONGQING WANG1

    BIOCELL, Vol.46, No.1, pp. 263-273, 2022, DOI:10.32604/biocell.2022.016306

    Abstract

    Strawberry mottle virus (SMoV) and strawberry vein banding virus (SVBV) cause diseases on strawberry plants, but the effect of coinfection of SMoV and SVBV on the growth, development, and defense system of strawberry (Fragaria × ananassa Duchesne) remains unknown. We investigated the effect of SMoV and SVBV co-infection on strawberry cultivar ‘Benihope’. The results showed that stem diameter, leaf size, leaf number, relative chlorophyll content, total chlorophyll content, photosynthetic parameters, and stomatal aperture of SMoV and SVBV co-infected strawberry (VIS) plants were in a weaker level than uninfected control plants, indicating that viruses inhibited the growth and photosynthesis of strawberry… More >
