    Abstract Cancer frequently develops resistance to the majority of chemotherapy treatments. This study aimed to examine the synergistic cytotoxic and antitumor effects of SGLT2 inhibitors, specifically Canagliflozin (CAN), Dapagliflozin (DAP), Empagliflozin (EMP), and Doxorubicin (DOX), using in vitro experimentation. The precise combination of CAN+DOX has been found to greatly enhance the cytotoxic effects of doxorubicin (DOX) in MCF-7 cells. Interestingly, it was shown that cancer cells exhibit an increased demand for glucose and ATP in order to support their growth. Notably, when these medications were combined with DOX, there was a considerable inhibition of glucose consumption, as well as reductions in… More > Graphic Abstract

    Emad Abd Al Rahman1, Nur Intan Raihana Ruhaiyem1,*, Majed Bouchahma2, Kamarul Imran Musa3

    Intelligent Automation & Soft Computing, Vol.36, No.3, pp. 3007-3028, 2023, DOI:10.32604/iasc.2023.032580

    Abstract This study offers a framework for a breast cancer computer-aided treatment prediction (CATP) system. The rising death rate among women due to breast cancer is a worldwide health concern that can only be addressed by early diagnosis and frequent screening. Mammography has been the most utilized breast imaging technique to date. Radiologists have begun to use computer-aided detection and diagnosis (CAD) systems to improve the accuracy of breast cancer diagnosis by minimizing human errors. Despite the progress of artificial intelligence (AI) in the medical field, this study indicates that systems that can anticipate a treatment plan once a patient has… More >

    NOMA with Adaptive Transmit Power Using Intelligent Reflecting Surfaces

    Raed Alhamad1,*, Hatem Boujemaa2

    Computer Systems Science and Engineering, Vol.45, No.2, pp. 2059-2070, 2023, DOI:10.32604/csse.2023.032610

    Abstract In this article, we use Intelligent Reflecting Surfaces (IRS) to improve the throughput of Non Orthogonal Multiple Access (NOMA) with Adaptive Transmit Power (ATP). The results are valid for Cognitive Radio Networks (CRN) where secondary source adapts its power to generate low interference at primary receiver. In all previous studies, IRS were implemented with fixed transmit power and previous results are not valid when the power of the secondary source is adaptive. In CRN, secondary nodes are allowed to transmit over the same band as primary users since they adapt their power to minimize the generated interference. Each NOMA user… More >

    BIOCELL, Vol.46, No.1, pp. 235-245, 2022, DOI:10.32604/biocell.2022.014997

    Abstract ATP depletion is one of the pathological bases in cerebral ischemia. Electro-acupuncture (EA) is widely used in clinical practice for ischemia. However, the mechanism of EA remains unclear. The purpose of this study was to investigate whether EA could activate the AMPK/PGC-1α/TFAM signaling pathway and, consequently, increase the preservation of ATP in rats with ischemia. In this study, 48 rats were randomly divided into four groups as a sham-operation control group (sham group), a middle cerebral artery occlusion group (MCAO group), an EA group, and an EA group blocked by the AMPK inhibitor compound C (EA + CC group) (N… More >

    Cell viability in the cadmium-stressed cell suspension cultures of tobacco is regulated by extracellular ATP, possibly by a reactive oxygen species-associated mechanism

    Zhenzhen SHI, Jiaxin CAO, Hailong PANG, Lingyun JIA, Kun SUN, Hanqing FENG*

    BIOCELL, Vol.44, No.1, pp. 89-99, 2020, DOI:10.32604/biocell.2020.08059

    Abstract Cadmium (Cd) is one of the most widespread and toxic heavy metals to plants. Extracellular ATP (exATP) is thought to be an extracellular effector in regulating the physiological responses of plant cells to environmental stresses. However, the function of exATP in Cd-stressed plant cells is much unknown. The present work showed that treating tobacco (Nicotiana tabacum L. cv. Bright Yellow-2) cell-suspension cultures with exogenous CdCl2 reduced the cell viability, exATP level, and Mg content. However, the production of reactive oxygen species (ROS), Cd content, and electrolyte leakage of the cells were enhanced by exogenous CdCl2. When the Cd-induced accumulation of… More >

    In vitro plant regeneration via indirect organogenesis from different explants of Lathyrus sativus L. and Lathyrus cicera L.

    Li RS1, YJ Tao2, FJ Liu2, X Hu2, QL Xu2, KY Li2

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 87-93, 2016, DOI:10.32604/phyton.2016.85.087

    Abstract The grass pea (Lathyrus sativus L.) and flatpod peavine (Lathyrus cicera L.) are the most economically important and widely cultivated Lathyrus species. However, their utilization is limited due to the presence of their endogenous toxin β-N-oxalyl-L-α, β-diaminopropionic acid (β-ODAP). Thus, a β-ODAP free variety should be developed through some plant breeding technique like either mutational breeding or genetic-manipulation. In this circumstance, the plant regeneration of Lathyrus species becomes a bottleneck. In the present study, an efficient system for in vitro regeneration of L. sativus with high β-ODAP levels, and L. cicera with low β-ODAP levels, was developed from different explants… More >

    Extracellular Matrix Elasticity Gives Integrin a Sweet Change via a p53/miRNA-532/atp2c1 Axis

    Yan Zu1,2, Qiang Li1, Chun Yang2,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 106-106, 2019, DOI:10.32604/mcb.2019.07132

    Abstract Extracellular matrix (ECM) elasticity affects the function of a variety of cells. Integrins are transmembrane receptors that considered to be a sensor of cellular mechanical stimulation. The activity of integrins is strongly influenced by glycans through glycosylation events and the establishment of glycan-mediated interactions. Our study found that the level of β1 integrin N-linked glycosylation was significantly down-regulated on softer ECM. Further, sialic acid is a common monosaccharide modified at the end of the sugar chain during N-glycosylation. We subjected the enriched sialylated glycoproteins to gel-based proteomic identification by tandem mass spectrometry and found that the chondrocytes seeded on stiff… More >

    Effect of the Lipophilic o-Naphthoquinone CG 10-248 on Rat Liver Mitochondria Structure and Function

    LIDIA M. LOPEZ*, AMANDA PELLEGRINO DE IRALDI*, PATRICIA H. CARRIZO**, MARTA DUBIN**, ANDRÉS O.M. STOPPANI**

    BIOCELL, Vol.26, No.2, pp. 237-245, 2002, DOI:10.32604/biocell.2002.26.237

    Abstract CG 10-248 (3,4-dihydro-2,2 dimethyl-9-chloro-2H-naphtho[1,2b]pyran-5,6-dione), a ß-lapachone analogue, modified the ultrastructure of rat liver mitochondria in vitro, in the absence of added oxidizable substrates. The condensed mitochondrial state was replaced by the orthodox or swollen state to a significant degree. The number of modified mitochondria depended on incubation time and quinone concentration, in the 25-100 µM range. Under the same experimental conditions, mitochondrial respiration was uncoupled as indicated by the increase in the rate of succinate oxidation by controlled mitochondria in metabolic state “4” (not in state “3”), and by the activation of latent F0 F1 -ATP synthase. Taking into account… More >
