Colon tumour cell death causes mTOR dependence by paracrine P2X4 stimulation

Solid cancers exhibit a dynamic balance between cell death and proliferation ensuring continuous tumour maintenance and growth(1,2). Increasing evidence links enhanced cancer cell apoptosis to paracrine activation of cells in the tumour microenvironment in ...

Brain connectivity and metacognition in persons with subjective cognitive decline (COSCODE): rationale and study design

Ileana Ozana Jelescu

Background Subjective cognitive decline (SCD) is the subjective perception of a decline in memory and/or other cognitive functions in the absence of objective evidence. Some SCD individuals however may suffer from very early stages of neurodegenerative dis ...

Antiangiogenic immunotherapy suppresses desmoplastic and chemoresistant intestinal tumors in mice

Matthias Lütolf, Michele De Palma, Mario Leonardo Squadrito, Mauro Delorenzi, Sina Nassiri, Alan Nicolas Thierry Guichard, Nikolche Gjorevski, Simone Ragusa, Borja Prat Luri, Laureline Wetterwald

Mutations in APC promote colorectal cancer (CRC) progression through uncontrolled WNT signaling. Patients with desmoplastic CRC have a significantly worse prognosis and do not benefit from chemotherapy, but the mechanisms underlying the differential respon ...

Type I interferon/IRF7 axis instigates chemotherapy-induced immunological dormancy in breast cancer

Mauro Delorenzi, Thibaut François Hugo Richard, Yu-Ting Huang

Neoadjuvant and adjuvant chemotherapies provide survival benefits to breast cancer patients, in particular in estrogen receptor negative (ER-) cancers, by reducing rates of recurrences. It is assumed that the benefits of (neo)adjuvant chemotherapy are due ...

RasGRP1 is a potential biomarker for stratifying anti-EGFR therapy response in colorectal cancer

Mauro Delorenzi, Delphine Yvette L Grun

Colorectal cancer (CRC) is the third most frequent neoplastic disorder and is a main cause of tumor-related mortality, as many patients progress to stage IV metastatic CRC. Standard care consists of combination chemotherapy (FOLFIRI or FOLFOX). Patients wi ...

Lymphoma Chemotherapy: Hungry Macrophages Strike the Final Blow

Michele De Palma

Macrophages modulate tumor response to chemotherapy; in this issue, Lossos and colleagues show that high-dose alkylating agents instigate a synthetic lethal program in lymphoma cells that is independent of DNA damage and involves recruitment and priming of ...

Carboplatin/paclitaxel, E7-vaccination and intravaginal CpG as tri-therapy towards efficient regression of genital HPV16 tumors

Douglas Hanahan, Gabriele Galliverti

High-risk human papillomavirus (HPV) are responsible for genital and oral cancers associated with the expression of the E6/E7 HPV oncogenes. Therapeutic vaccines targeting those oncogenes can only partially control tumor progression, highlighting the neces ...

Chemokine profiling in serum from patients with ovarian cancer reveals candidate biomarkers for recurrence and immune infiltration

Gianrocco Lazzari, Agata Mlynska

The management of advanced ovarian cancer is challenging due to the high frequency of recurrence, often associated with the development of resistance to platinum-based chemotherapy. Molecular analyses revealed the complexity of ovarian cancer with particul ...

Anti-angiogenic immunotherapy for lung cancer

Ece Kadioglu

Lung cancer is the leading cause of cancer-associated deaths worldwide. Platinum-based chemotherapy is the most common therapeutic approach in advanced non-small cell lung cancer (NSCLC), particularly for tumors that carry non-druggable activating mutation ...

Chemotherapy elicits pro-metastatic extracellular vesicles in breast cancer models

Ioanna Keklikoglou, Michele De Palma, Mario Leonardo Squadrito, Chiara Cianciaruso, Esra Güç, Alan Nicolas Thierry Guichard, Antonino Cassarà

Cytotoxic chemotherapy is an effective treatment for invasive breast cancer. However, experimental studies in mice also suggest that chemotherapy has pro-metastatic effects. Primary tumours release extracellular vesicles (EVs), including exosomes, that can ...

Advancing immunotherapy for HPV-related cancers: Improving therapeutic vaccination approaches and understanding the immunosuppressive role of myeloid cells

Gabriele Galliverti

Human Papilloma Viruses (HPVs) are the most common sexually transmitted agents worldwide, and chronic infection with oncogenic HPVs can lead to the development of lesions in the cervix, the vulva, and the head and neck region. In some patients, these lesio ...

Epigenetic approach for angiostatic therapy: promising combinations for cancer treatment

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Ume-Gulsoom Abdul, Marije Trudi Te Winkel

Cancer cells are often dependent on epigenetic pathways for their survival. Consequently, drugs that target the epigenome, rather than the underlying DNA sequence, are currently attracting considerable attention. In recent years, the first epigenetic drugs ...

Multidimensional Texture Analysis for Improved Prediction of Ultrasound Liver Tumor Response to Chemotherapy Treatment

Dimitri Nestor Alice Van De Ville, Adrien Raphaël Depeursinge

The number density of scatterers in tumor tissue contribute to a heterogeneous ultrasound speckle pattern that can be difficult to discern by visual observation. Such tumor stochastic behavior becomes even more challenging if the tumor texture heterogeneit ...

Development of mass spectrometric methods to understand the mechanism of action of transition metal-based anticancer compounds

Fook Seng Ronald Lee

Metal based anti-cancer drugs (metallodrugs) such as cisplatin are a cornerstone of cancer chemotherapy. However, development of this class of compound has been hindered by our lack of understanding of how they function. This is mainly because existing met ...

Whole Cell Target Engagement Identifies Novel Inhibitors of Mycobacterium tuberculosis Decaprenylphosphoryl-beta-D-ribose Oxidase

John McKinney, Neeraj Dhar

We have targeted the Mycobacterium tuberculosis decaprenylphosphoryl-beta-D-ribose oxidase (Mt-DprE1) for potential chemotherapeutic intervention of tuberculosis. A multicopy suppression strategy that overexpressed Mt-DprEl in M. bovis BCG was used to prof ...

Rational design of organic and organometallic thermoresponsive or tumor-selective anticancer drugs and their in vitro and in vivo biological evaluation

Catherine Marie Amélie Clavel

Conventional chemotherapy leads to severe side-effects such as nephrotoxicity, nausea and vomiting and fatigue along with drug resistance. Alkylating agents used to treat cancer were even shown to provoke second cancers, often years after the end of chemot ...

Tumor Vessel Normalization by Chloroquine Independent of Autophagy

Freddy Radtke

Chloroquine (CQ) has been evaluated as an autophagy blocker for cancer treatment, but it is unknown if it acts solely by inhibiting cancer cell autophagy. We report that CQ reduced tumor growth but improved the tumor milieu. By normalizing tumor vessel str ...

Macrophage regulation of tumor responses to anticancer therapies

Michele De Palma

Tumor-associated macrophages (TAMs) promote key processes in tumor progression, like angiogenesis, immunosuppression, invasion, and metastasis. Increasing studies have also shown that TAMs can either enhance or antagonize the antitumor efficacy of cytotoxi ...

Single walled carbon nanotubes as drug delivery vehicles: Targeting doxorubicin to tumors

Paul Joseph Dyson, Zhaofu Fei, Xianfu Zhang

Single walled carbon nanotubes (SWNTs) are emerging as promising delivery vehicles for cancer diagnostics and chemotherapies due to their unique properties, including, remarkable cell membrane penetrability, high drug-carrying capacities, pH-dependent ther ...

HRG inhibits tumor growth and metastasis by inducing macrophage polarization and vessel normalization through downregulation of PlGF

Michele De Palma, Mario Leonardo Squadrito, Damya Laoui

Polarization of tumor-associated macrophages (TAMs) to a proangiogenic/immune-suppressive (M2-like) phenotype and abnormal, hypoperfused vessels are hallmarks of malignancy, but their molecular basis and interrelationship remains enigmatic. We report that ...
