    BIOCELL, Vol.44, No.2, pp. 137-145, 2020, DOI:10.32604/biocell.2020.08500
    Abstract Focal adhesions are polyproteins linked to extracellular matrix and cytoskeleton, which play an important role in the process of transforming force signals into intracellular chemical signals and subsequently triggering related physiological or pathological reactions. The cytoskeleton is a network of protein fibers in the cytoplasm, which is composed of microfilaments, microtubules, intermediate filaments, and cross-linked proteins. It is a very important structure for cells to maintain their basic morphology. This review summarizes the process of fluid shear stress transduction mediated by focal adhesion and the key role of the cytoskeleton in this process, which focuses on the focal adhesion and… More >

    BIOCELL, Vol.44, No.2, pp. 157-166, 2020, DOI:10.32604/biocell.2020.09917
    Abstract Prophages are temperate phages integrated into the host bacterial genome. They play an important role in the adaptation and the pathogenicity of bacteria, especially pathogenic bacteria. In this review, we described the distribution of prophages in different hosts and different environments, and focused on the significance of prophages. At the singlecell level, prophages can help the host adapt to harsh external environments by directly carrying virulence genes, encoding regulatory factors and activating lysogeny. At the population level, prophages can influence the overall evolutionary direction and ecological function of the host bacterial community. This review will help us understand the important… More >

    EUN NA1, MYOUNGWON CHOI2, INDAL PARK2, SUNYOUNG LIM3,*
    BIOCELL, Vol.44, No.2, pp. 193-199, 2020, DOI:10.32604/biocell.2020.08648
    Abstract We investigated the effect of black sea bream extracts on changes in pro-inflammatory and anti-inflammatory cytokines induced by lipopolysaccharide (LPS) in murine splenocytes. The levels of pro-inflammatory cytokines [interleukin (IL)-6, tumor necrosis factor-α (TNF-α), IL-12/IL-23(p40) and IL-17A] and anti-inflammatory cytokines [IL-4, IL-10 and interferon-γ (IFN-γ)] were assessed. Incubation of murine splenocytes with acetone+methylene chloride (A+M) and methanol (MeOH) extracts significantly decreased LPS-induced IL-6, IL-12/IL-23(p40) and IL-17A productions after 6 h incubation (p < 0.05). The A+M and MeOH extracts significantly increased LPS-induced IL-4 and IFN-γ productions at 48 and 72 h incubation (p < 0.05). Treatment with A+M extract resulted… More >

    MicroRNA-382 inhibits the proliferation of mouse spermatogonia by targeting Kmt5a

    YI ZHENG#, PENGFEI ZHANG#, JINSHENG ZHU#, LINGKAI ZHANG, WENXIAN ZENG*
    BIOCELL, Vol.44, No.2, pp. 201-207, 2020, DOI:10.32604/biocell.2020.08770
    Abstract Spermatogenesis is a highly efficient and intricate process in the testis by which mature spermatozoa are produced daily to maintain lifelong male fertility. Essential to this process are spermatogonia capable of both proliferation and differentiation. Nevertheless, the underlying mechanisms for spermatogonial proliferation and differentiation remain poorly understood. MicroRNAs (miRNAs) are a category of non-coding small RNAs with regulatory functions by binding to the 3’ untranslated region (UTR) of the target mRNA. Previous studies have demonstrated that miRNAs are capable of modulating cell proliferation, differentiation and apoptosis, but the roles of individual miRNAs in spermatogonial fate determination remain largely elusive.

    Exogenous dendritic cells aggravate atherosclerosis via P-selectin/ PSGL-1 pathway

    LEI ZHONG1, LEI GUO1, ZHISHUAI YE2, SHANFENG ZHANG3, RONGCHONG HUANG2,*
    BIOCELL, Vol.44, No.2, pp. 225-236, 2020, DOI:10.32604/biocell.2020.08714
    Abstract Studies have found that a large number of inflammatory cells, P-selectin, and mature dendritic cells (DCs) are expressed in the damaged and shoulder parts of atherosclerotic plaque, which demonstrates that P-selectin and mature DCs participate in the immune inflammatory response leading to the development of atherosclerosis. However, it is unclear how the above factors interact in this setting. In this study, we investigated the role of P-selectin and its receptor, P-selectin glycoprotein ligand (PSGL)-1 in atherosclerosis, with the finding that DC surface marker expression was consistently high in the P-selectin group while consistently low in the PGSL-1 + DCs group,… More >

    BIOCELL, Vol.44, No.2, pp. 237-246, 2020, DOI:10.32604/biocell.2020.08887
    Abstract Most studies focus on the adaptive immune cells in the GVHD pathogenesis, while little is known about innate immune cells in GVHD occurrence and development, especially macrophages. Meanwhile, a higher incidence of graft versus host disease (GVHD) is also found in the elderly patients. Though advances have been made in the modification of macrophages influenced by the inflamm-ageing, there is still no review on the role of macrophages in GVHD and the association between GVHD and the altered macrophages by inflamm-ageing. In this review, we focus on the potential age-related modifications of macrophage in GVHD, which contributes to the change… More >

    BIOCELL, Vol.44, No.2, pp. 247-255, 2020, DOI:10.32604/biocell.2020.08835
    Abstract While phthalate acid esters (PAEs) cannot fluoresce alone, they can be detected by fluorescence spectroscopy after chelation with bovine serum albumin (BSA). In this study, the types of amino acid residues at the active site of PAEs chelated with BSA were determined using molecular docking technology. A modification scheme of BSA with higher detection sensitivity fluorescence spectroscopy for PAEs was proposed based on the docking results and constructed for a novel BSA structure with a higher detection sensitivity of fluorescence spectroscopy using a homologous modeling method. Density functional theory (DFT) was employed to explore the influence before and after BSA… More >
