    Jie Zhang, Jiaxiang Zhao*, Pengchang Xu

    CMES-Computer Modeling in Engineering & Sciences, Vol.131, No.2, pp. 905-917, 2022, DOI:10.32604/cmes.2022.019097 - 14 March 2022

    Abstract Accurately, reliably and rapidly identifying intrinsically disordered (IDPs) proteins is essential as they often play important roles in various human diseases; moreover, they are related to numerous important biological activities. However, current computational methods have yet to develop a network that is sufficiently deep to make predictions about IDPs and demonstrate an improvement in performance. During this study, we constructed a deep neural network that consisted of five identical variant models, ResNet18, combined with an MLP network, for classification. Resnet18 was applied for the first time as a deep model for predicting IDPs, which allowed More >

    Crosslinking-mediated activation of the FcεRI: Does it need antigen for success?

    MICHAEL HUBER*, SANDRO CAPELLMANN

    BIOCELL, Vol.46, No.5, pp. 1125-1129, 2022, DOI:10.32604/biocell.2022.018513 - 06 January 2022

    Abstract Mast cells (MCs), hematopoietic cells of the myeloid lineage, are well-known for their pro-inflammatory nature contributing to the development of various allergic and autoimmune diseases. One of the characteristic receptors on MCs, the high-affinity receptor for IgE (FcεRI), is activated in its IgE-bound state via binding and crosslinking by polyvalent antigen. This results in its phosphorylation by the SRC family kinase LYN, initiating differential signaling pathways, eventually triggering immunological effector functions, such as degranulation and cytokine production. Few publications have reported on FcεRI-dependent but antigen-independent MC activation by antibody-mediated crosslinking of membrane molecules (e.g., transmembrane More >

    YUKA IKEDA, NOZOMI NAGASE, AI TSUJI, KURUMI TANIGUCHI, YASUKO KITAGISHI, SATORU MATSUDA*

    BIOCELL, Vol.46, No.5, pp. 1163-1167, 2022, DOI:10.32604/biocell.2022.018177 - 06 January 2022

    Abstract Stemness of cancer cells contains limitless self-renewal proliferation. For the purpose of proliferation, secretome might exert its effects via the paracrine signaling. Specific microRNAs enclosed in the secretome of cancer stem cells could regulate the expression of anti-proliferative APRO family proteins. The biological functions of APRO family proteins seems to be quite intricate, however, which might be a key modulator of microRNAs, then could regulate the proliferation of cancer cells. In addition to affecting proliferation/differentiation during cellular development, APRO family proteins might also play an imperious role on keeping homeostasis in healthy stem cells under a More >

    Mechanism of tobacco osmotin gene in plant responses to biotic and abiotic stress tolerance: A brief history

    HAKIM MANGHWAR1,#,*, AMJAD HUSSAIN2,#

    BIOCELL, Vol.46, No.3, pp. 623-632, 2022, DOI:10.32604/biocell.2022.017316 - 18 November 2021

    Abstract Plants are recurrently exposed to myriads of biotic and abiotic stresses leading to several biochemical and physiological variations that cause severe impacts on plant growth and survival. To overcome these challenges, plants activate two primary defense mechanisms, such as structural response (cell wall strengthening and waxy epidermal cuticle development) and metabolic changes, including the synthesis of anti-microbial compounds and proteins, especially the pathogenesis-related (PR) proteins. PR proteins are members of a super large family of defense proteins that exhibit antimicrobial activities. Their over-expression in plants provides tolerance to many abiotic and biotic stresses. PR proteins… More >

    Nanoscale interactions between the nicotinic acetylcholine receptor and cholesterol

    FRANCISCO J. BARRANTES#,*

    BIOCELL, Vol.45, No.6, pp. 1479-1484, 2021, DOI:10.32604/biocell.2021.016502 - 01 September 2021

    Abstract Cholesterol is a major lipid in biological membranes. It not only plays a structural role but also modulates a wide range of functional properties of neurotransmitter and hormone receptors and ion channels. The membraneembedded segments of the paradigm neurotransmitter receptor for acetylcholine (nAChR) contain linear sequences of amino acids with the capacity to recognize cholesterol. These cholesterol consensus domains have been designated as “CARC” and its mirror sequence “CRAC”. CARC preferentially occurs in the exoplasmic-facing membrane leaflet, and CRAC, in the cytoplasmic-facing hemilayer. Both motifs are highly conserved among ion-channel and neurotransmitter receptor proteins in… More >

    iPhosD-PseAAC: Identification of phosphoaspartate sites in proteins using statistical moments and PseAAC

    ALAA OMRAN ALMAGRABI1, YASER DAANIAL KHAN2, SHER AFZAL KHAN3,*

    BIOCELL, Vol.45, No.5, pp. 1287-1298, 2021, DOI:10.32604/biocell.2021.013770 - 12 July 2021

    Abstract Phosphoaspartate is one of the major components of eukaryotes and prokaryotic two-component signaling pathways, and it communicates the signal from the sensor of histidine kinase, through the response regulator, to the DNA alongside transcription features and initiates the transcription of correct response genes. Thus, the prediction of phosphoaspartate sites is critical, and its experimental identification can be expensive, time-consuming, and tedious. For this purpose, we propose iPhosD-PseAAC, a new computational model for predicting phosphoaspartate sites in a particular protein sequence using Chou’s 5-steps rues: (1) Benchmark dataset. (2) The feature extraction techniques such as pseudo More >
