Whole-genome doubling drives oncogenic loss of chromatin segregation

Elisa Oricchio, Daniele Tavernari, Natalya Katanayeva, Ruxandra-Andreea Lambuta, Juan Diaz Miyar, Giovanni Ciriello

Whole-genome doubling (WGD) is a recurrent event in human cancers and it promotes chromosomal instability and acquisition of aneuploidies(1-8). However, the three-dimensional organization of chromatin in WGD cells and its contribution to oncogenic phenotyp ...

Using Dynamic Features for Automatic Cervical Precancer Detection

Jean-Philippe Thiran, Roser Vinals Terres, Mohammad Saeed Rad

Cervical cancer remains a major public health concern in developing countries due to financial and human resource constraints. Visual inspection with acetic acid (VIA) of the cervix was widely promoted and routinely used as a low-cost primary screening tes ...

Emodin Inhibits Inflammation, Carcinogenesis, and Cancer Progression in the AOM/DSS Model of Colitis-Associated Intestinal Tumorigenesis

Jelena Zaric

Colorectal cancer (CRC) is one of the most common cancer worldwide. Chronic inflammation contributes to CRC development and progression. Emodin, is a natural anthraquinone derivative with anti-oxidant, anti-inflammatory, and anti-tumor activities. We used ...

Nanoparticle Conjugation of Human Papillomavirus 16 E7-long Peptides Enhances Therapeutic Vaccine Efficacy against Solid Tumors in Mice

Douglas Hanahan, Mélanie Louise Tichet, Melody Swartz, Stephan Wullschleger, Gabriele Galliverti, Sylvie Hauert

Treatment of patients bearing human papillomavirus (HPV)-related cancers with synthetic long-peptide (SLP) therapeutic vaccines has shown promising results in clinical trials against premalignant lesions, whereas responses against later stage carcinomas ha ...

Intraductal patient-derived xenografts of estrogen receptor α-positive breast cancer recapitulate the histopathological spectrum and metastatic potential of human lesions

Cathrin Brisken, Georgios Sflomos, Ayyakkannu Ayyanan, Laura Battista, Valentina Scabia, Maryse Fiche, Patrik Aouad, Valérian Charles Robert Dormoy

Estrogen receptor α-positive (ER-positive) or 'luminal' breast cancers were notoriously difficult to establish as patient-derived xenografts (PDXs). We and others recently demonstrated that the microenvironment is critical for ER-positive tumor cells; when ...

Enhanced Rate of Acquisition of Point Mutations in Mouse Intestinal Adenomas Compared to Normal Tissue

Jörg Hülsken, Paloma Ordonez Moran

The most prevalent single-nucleotide substitution (SNS) found in cancers is a C-to-T substitution in the CpG motif. It has been proposed that many of these SNSs arise during organismal aging, prior to transformation of a normal cell into a precancerous/can ...

Enhancers of notch signaling and their use in the treatment of cancers and malignancies medicable by upregulation of notch

Jieping Zhu, Viktoria Reinmüller

The present invention relates to the use for enhancing Notch signaling in an individual, of a compound showing the general formula (I) and/or a pharmaceutically acceptable salt or ester thereof, for the treatment of a disease selected from the group of der ...

Red blood cells ageing markers: a multi-parametric analysis

Gerardo Turcatti, Niels Erik Lion, Benjamin Rappaz, David Crettaz, Michel Prudent, Manon Sandra Bardyn

Background. Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 degrees C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells ac ...

Review of the role played by the photosensitizer's photobleaching during photodynamic therapy

Georges Wagnières, Matthieu Philippe Emmanuel Zellweger

Photodynamic therapy (PDT) is based on the combined administration of photosensitizing drugs and light to treat a variety of malignant, pre-malignant and also non-malignant diseases. The reactive species resulting from the excitation of the photosensitizer ...

Phenotypic Heterogeneity in Mycobacterium tuberculosis

John McKinney, Neeraj Dhar, Giulia Manina

The interaction between the host and the pathogen is extremely complex and is affected by anatomical, physiological, and immunological diversity in the microenvironments, leading to phenotypic diversity of the pathogen. Phenotypic heterogeneity, defined as ...

Combined CSL and p53 downregulation promotes cancer-associated fibroblast activation

Cathrin Brisken, Melody Swartz, Witold Waldemar Kilarski, Csaba Ferenc László, Elena Menietti, Dania Al Labban

Stromal fibroblast senescence has been linked to ageing-associated cancer risk. However, density and proliferation of cancer-associated fibroblasts (CAFs) are frequently increased. Loss or downmodulation of the Notch effector CSL (also known as RBP-Jκ) in ...

Three-dimensional chemotaxis-driven aggregation of tumor cells

Alessandro De Simone, Andrea Gamba

One of the most important steps in tumor progression involves the transformation from a differentiated epithelial phenotype to an aggressive, highly motile phenotype, where tumor cells invade neighboring tissues. Invasion can occur either by isolated mesen ...

Improving tumor heterogeneity MRI assessment with histograms

Nathalie Just

By definition, tumours are heterogeneous. They are defined by marked differences in cells, microenvironmental factors (oxygenation levels, pH, VEGF, VPF and TGF-α) metabolism, vasculature, structure and function that in turn translate into heterogeneous dr ...

Engineered insulin-like growth factor-1 for improved smooth muscle regeneration

Jeffrey Alan Hubbell, Peter Frey, Kristen Lorentz, Lirong Yang

Insulin-like growth factor-1 (IGF-1) has been shown to induce potent mitogenic responses in various cell types, yet its sustained local delivery is still an underdeveloped domain in the clinic. We report here an engineered IGF-1 that facilitates extended l ...

Synthesis of C-linked Disaccharides and Analogues as Biomimetics of the TF Epitope

Maria Kolympadi

Glycoproteins and glycolipids are major components of the outer surface of mammalian cells. Their carbohydrate moieties, which are directed into the outer environment, serve as ligands for receptor proteins, such as lectins, pathogen proteins and antibodie ...
