    Circulating Tumor DNA in Cervical Cancer: Clinical Utility and Medico-Legal Perspectives

    Abdulrahman K. Sinno1, Aisha Mustapha1, Navya Nair1, Simona Zaami2, Lina De Paola2, Valentina Billone3, Eleonora Conti3, Giuseppe Gullo3,*, Pasquale Patrizio4

    Oncology Research, Vol.34, No.1, 2026, DOI:10.32604/or.2025.072176 - 30 December 2025

    Abstract Cervical cancer related to human papillomavirus (HPV) is a leading cause of cancer-related mortality among women worldwide. Cancer cells release fragments of their DNA, known as circulating tumor DNA (ctDNA), which can be detected in bodily fluids. A PubMed search using the terms “ctHPV” or “circulating tumor DNA” and “cervical cancer”, limited to the past ten years, identified 104 articles, complemented by hand-searching for literature addressing medico-legal implications. Studies were evaluated for relevance and methodological quality. Detection and characterization of circulating tumor HPV DNA (ctHPV DNA) have emerged as promising tools for assessing prognosis and More >

    A Comparative Study of Data Representation Techniques for Deep Learning-Based Classification of Promoter and Histone-Associated DNA Regions

    Sarab Almuhaideb1,*, Najwa Altwaijry1, Isra Al-Turaiki1, Ahmad Raza Khan2, Hamza Ali Rizvi3

    CMC-Computers, Materials & Continua, Vol.85, No.2, pp. 3095-3128, 2025, DOI:10.32604/cmc.2025.067390 - 23 September 2025

    Abstract Many bioinformatics applications require determining the class of a newly sequenced Deoxyribonucleic acid (DNA) sequence, making DNA sequence classification an integral step in performing bioinformatics analysis, where large biomedical datasets are transformed into valuable knowledge. Existing methods rely on a feature extraction step and suffer from high computational time requirements. In contrast, newer approaches leveraging deep learning have shown significant promise in enhancing accuracy and efficiency. In this paper, we investigate the performance of various deep learning architectures: Convolutional Neural Network (CNN), CNN-Long Short-Term Memory (CNN-LSTM), CNN-Bidirectional Long Short-Term Memory (CNN-BiLSTM), Residual Network (ResNet), and… More >

    Abstract Objectives: The Sorbin and SH3 domain containing 1 (SORBS1), a protein linked to insulin signaling CBL interaction, was investigated for its role in pancreatic cancer apoptosis. This study explored polyphyllin H (PPH)’s ability to restore SORBS1-knockdown-mediated repair functions. Methods: PANC-1 cells were divided into Blank, overexpression (OE), and knockdown groups. CCK-8 assays assessed proliferation and drug toxicity. Western blot and flow cytometry analyzed SORBS1 levels and PPH effects. Comet assays quantified DNA damage. Subcutaneous xenograft tumors in nude mice (Blank vs. knockdown) were treated with PPH to evaluate in vivo efficacy. SORBS1-H2AX gene correlation was analyzed… More > Graphic Abstract

    Oncology Research, Vol.33, No.8, pp. 1875-1893, 2025, DOI:10.32604/or.2025.063843 - 18 July 2025

    Abstract Malignant melanoma, characterized by its high metastatic potential and resistance to conventional therapies, presents a major challenge in oncology. This review explores the current status and advancements in tumor vaccines for melanoma, focusing on peptide, DNA/RNA, dendritic cell, tumor cell, and neoantigen-based vaccines. Despite promising results, significant challenges remain, including the immunosuppressive tumor microenvironment, patient heterogeneity, and the need for more effective antigen presentation. Recent strategies, such as combining vaccines with immune checkpoint inhibitors (ICIs), aim to counteract immune evasion and enhance T cell responses. Emerging approaches, including personalized neoantigen vaccines and the use of More > Graphic Abstract

    Addressing Class Overlap in Sonic Hedgehog Medulloblastoma Molecular Subtypes Classification Using Under-Sampling and SVD-Enhanced Multinomial Regression

    Isra Mohammed1, Mohamed Elhafiz M. Musa2, Murtada K. Elbashir3,*, Ayman Mohamed Mostafa3, Amin Ibrahim Adam4, Mahmood A. Mahmood3, Areeg S. Faggad5

    CMC-Computers, Materials & Continua, Vol.84, No.2, pp. 3749-3763, 2025, DOI:10.32604/cmc.2025.063880 - 03 July 2025

    Abstract Sonic Hedgehog Medulloblastoma (SHH-MB) is one of the four primary molecular subgroups of Medulloblastoma. It is estimated to be responsible for nearly one-third of all MB cases. Using transcriptomic and DNA methylation profiling techniques, new developments in this field determined four molecular subtypes for SHH-MB. SHH-MB subtypes show distinct DNA methylation patterns that allow their discrimination from overlapping subtypes and predict clinical outcomes. Class overlapping occurs when two or more classes share common features, making it difficult to distinguish them as separate. Using the DNA methylation dataset, a novel classification technique is presented to address… More >

    Abstract Lynch syndrome (LS), also known as hereditary non-polyposis colorectal cancer (HNPCC), is an inherited condition associated with a higher risk of colorectal cancer (CRC) and other cancers. It is caused by germline mutations in DNA mismatch repair (MMR) genes, including MLH1, MSH2, MSH6 and PMS2. These mutations lead to microsatellite instability (MSI) and defective DNA repair mechanisms, resulting in increased cancer risk. Early detection of LS is crucial for effective management and cancer prevention. Endoscopic surveillance, particularly regular colonoscopy, is recommended for individuals with LS to detect CRC at early stages. Additionally, universal screening of CRC for More > Graphic Abstract

    Mohamed Medani1, Yahia Said2, Nashwan Adnan Othman3,4, Farrukh Yuldashev5, Mohamed Kchaou6, Faisal Khaled Aldawood6, Bacha Rehman7,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.143, No.1, pp. 1049-1070, 2025, DOI:10.32604/cmes.2025.063405 - 11 April 2025

    Abstract Satellite images are widely used for remote sensing and defence applications, however, they are subject to a variety of threats. To ensure the security and privacy of these images, they must be watermarked and encrypted before communication. Therefore, this paper proposes a novel watermarked satellite image encryption scheme based on chaos, Deoxyribonucleic Acid (DNA) sequence, and hash algorithm. The watermark image, DNA sequence, and plaintext image are passed through the Secure Hash Algorithm (SHA-512) to compute the initial condition (keys) for the Tangent-Delay Ellipse Reflecting Cavity Map (TD-ERCS), Henon, and Duffing chaotic maps, respectively.
