    Abstract Propofol, a common intravenous anesthetic used in clinical, has been shown to regulate cells proliferation, inflammation, angiogenesis and metastasis as well as exerting anti-cancer effect in several different types of cancer. However, the functions and mechanisms of propofol in lactate secretion and invasion of cancer cells remain unknown. The primary aim of this study was to investigate the role of propofol in cells migration and invasion of colon cancer (CRC). Scratches assay, Transwell assay were used to detect colon cells migration and invasion. Real-time Quantitative Polymerase Chain Reaction (RT-qPCR), Western blotting were utilized to detect the expression of related molecules.… More >

    Abstract Specific cell subpopulations identified as cancer stem cells (CSCs) can be found in basal cell carcinoma (BCC). Generally, CSCs have a marked trans-differentiation potential that could potentially be used in differentiation therapies. However, there are no studies regarding BCC CSCs multipotency. The aim of the study was to analyze the characteristic of CSCs of BCC with emphasis on their differentiation potential upon specific induction. Specific staining and cell morphology were used for differentiation confirmation, along with the expression analysis of osteogenic (ALP, BSP, Runx2, OCN, BMP2), chondrogenic (COL1 and COL2A1), adipogenic (PPAR-γ) and neurogenic (Nestin and MAP2) markers. BCC CSCs… More >

    An Automated Brain Image Analysis System for Brain Cancer using Shearlets

    R. Muthaiyan1,*, Dr M. Malleswaran2

    Computer Systems Science and Engineering, Vol.40, No.1, pp. 299-312, 2022, DOI:10.32604/csse.2022.018034

    Abstract In this paper, an Automated Brain Image Analysis (ABIA) system that classifies the Magnetic Resonance Imaging (MRI) of human brain is presented. The classification of MRI images into normal or low grade or high grade plays a vital role for the early diagnosis. The Non-Subsampled Shearlet Transform (NSST) that captures more visual information than conventional wavelet transforms is employed for feature extraction. As the feature space of NSST is very high, a statistical t-test is applied to select the dominant directional sub-bands at each level of NSST decomposition based on sub-band energies. A combination of features that includes Gray Level… More >

    Nanotherapeutics approaches to improve the efficacy of CAR-T cells in solid tumors

    FRANCESCO MAININI*

    BIOCELL, Vol.45, No.5, pp. 1171-1173, 2021, DOI:10.32604/biocell.2021.017399

    Abstract Adoptive cell therapy and Immune Checkpoint Blockade Inhibitors have recently revolutionized the field of oncology. However, these types of immunotherapeutic approaches have limited success in treating solid tumors. In particular, chimeric antigen receptor (CAR)-T cells efficacy is hampered by immunosuppressive signals in the tumor microenvironment (TME) and by a limited infiltration of re-infused T cells to the tumor site. The field of nanobiotechnology applied to oncology is also rapidly expanding. Nanoparticles-based delivery systems can be employed to modulate the activity of immune cells present in the TME enhancing the efficacy of CAR-T cells. Interestingly, nano-backpacks can be attached to CAR-T… More >

    KIFC1 overexpression promotes prostate cancer cell survival and proliferation in vitro by clustering of amplified centrosomes via interaction with Centrin 2

    ANZANA PARVIN1,3, BANG-HONG WEI1, SHUANG-LI HAO1, WAN-XI YANG1,*, FU-QING TAN1,2,*

    BIOCELL, Vol.45, No.5, pp. 1369-1391, 2021, DOI:10.32604/biocell.2021.016654

    Abstract Mitotic kinesin KIFC1 plays critical roles in mitosis by regulating the spindle length, pole formation, and known for clustering extra centrosomes in cancer cells. Centrosome clustering is associated with the survival of cancer cells, but this phenomenon remains obscure in prostate cancer (PCa). The present study demonstrated that PCa cells showed centrosome amplification and clustering during interphase and mitosis, respectively. KIFC1 is highly expressed in PCa cells and tumor tissues of prostatic adenocarcinoma (PAC) patients. Up-regulation of KIFC1 facilitated the PCa cell survival in vitro by ensuring bipolar mitosis through clustering the multiple centrosomes, suggesting centrosome clustering could be a… More >

    Abstract Helicobacter pylori infection has been significantly linked to Peptic Ulcer Disease and Gastric Cancer. Metabolomic fingerprinting may offer a principal way of early diagnosis and to understand the molecular mechanism of H. pylori-induced pathogenicity. The rationale of the study is to explore the underlying distinct metabolic mechanisms of H. pylori-induced PUD and to identify potential biomarkers for disease diagnosis and associated risks using Gas chromatography/mass spectrometry. GC/MS-based analytical method was used to compare metabolic profiles of healthy controls (N = 20) and peptic ulcer patients (N = 45). Acquired metabolomic data were analyzed by constructing a diagnostic model using principal… More >

    BIOCELL, Vol.45, No.5, pp. 1337-1353, 2021, DOI:10.32604/biocell.2021.015464

    Abstract This study examined if the anti-tumorigenesis effect of Exendin-4 in HT29 and HCT116 colorectal cancer (CRC) involves modulation of SIRT1 and Akt/GSR3K/β-catenin/NF-κB axis. HT29 and HCT116 cells were treated either with increasing levels of Exendin-4 (0.0-200 µM) or with Exendin-4 (at its IC50) in the presence or absence of EX-527 (10 µM/a selective SIRT1 inhibitor) or Exendin-4 (9-39) amide (E (9-39) A) (1 µM/an Exendin-4 antagonist). In a dose-dependent manner, Exendin-4 inhibited cell survival, but enhanced levels of lactate dehydrogenase (LDH) and single-stranded DNA (ssDNA) in both HT29 and HCT116. In both cell lines and at it has an IC50More >

    Aneuploidy: An opportunity within single-cell RNA sequencing analysis

    JOE R. DELANEY*

    BIOCELL, Vol.45, No.5, pp. 1167-1170, 2021, DOI:10.32604/biocell.2021.017296

    Abstract Single-cell sequencing data has transformed the understanding of biological heterogeneity. While many flavors of single-cell sequencing have been developed, single-cell RNA sequencing (scRNA-seq) is currently the most prolific form in published literature. Bioinformatic analysis of differential biology within the population of cells studied relies on inferences and grouping of cells due to the spotty nature of data within individual cell scRNA-seq gene counts. One biologically relevant variable is readily inferred from scRNA-seq gene count tables regardless of individual gene representation within single cells: aneuploidy. Since hundreds of genes are present on chromosome arms, high-quality inferences of aneuploidy can be made… More >

    Breast Cancer Classification Using Deep Convolution Neural Network with Transfer Learning

    Hanan A. Hosni Mahmoud*, Amal H. Alharbi, Doaa S. Khafga

    Intelligent Automation & Soft Computing, Vol.29, No.3, pp. 803-814, 2021, DOI:10.32604/iasc.2021.018607

    Abstract In this paper, we aim to apply deep learning convolution neural network (Deep-CNN) technology to classify breast masses in mammograms. We develop a Deep-CNN combined with multi-feature extraction and transfer learning to detect breast cancer. The Deep-CNN is utilized to extract features from mammograms. A support vector machine (SVM) is then trained on the Deep-CNN features to classify normal, benign, and cancer cases. The scoring features from the Deep-CNN are coupled with texture features and used as inputs to the final classifier. Two texture features are included: texture features of spatial dependency and gradient-based histograms. Both are employed to locate… More >

    Faizah A. AlMalki1, Aziza M. Hassan2,*, Zeinab M. Klaab1, Soliman Abdulla3, Antonio Pizzi4

    Journal of Renewable Materials, Vol.9, No.12, pp. 2077-2092, 2021, DOI:10.32604/jrm.2021.016173

    Abstract Recently, natural substances in the form of nanoparticles are increasingly being used in different field, particularly in medicines to enhance their beneficial effects in treatment and prevention. Cancer cells of the breast (MCF-7) have been chosen to be examined and treated in vitro with conventional drug Tamoxifen (Tam) and tannin nanoparticles extract (NP99) individually or in combination. MTT reagent has been applied to assess the cell viability and propagation percentage, DNA fragmentation and mRNA relative expression of apoptotic genes to study the cell death pathway. The results showed that Tam and tannin NP99 triggered cytotoxic activity towards the MCF-7 cell.… More >
