Cytokine-armed dendritic cell progenitors for antigen-agnostic cancer immunotherapy

Ali Ghasemi

Dendritic cells (DCs) are specialized myeloid cells with the ability to uptake, process, and present antigens to T lymphocytes. They also generate cytokine and chemokine gradients that regulate immune cell trafficking, activation, and function. Monocyte-de ...

A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Olga Marie Louise Rosspopoff, Cyril David Son-Tuyên Pulver, Romain Forey, Florian Huber

Heterochromatin loss and genetic instability enhance cancer progression by favoring clonal diversity, yet uncontrolled replicative stress leads to mitotic catastrophe and inflammatory responses that promote immune rejection. KRAB domain-containing zinc fin ...

The role of LRRK2 in lung adenocarcinoma

Aspasia Gkasti

Lung cancer is the leading cause of cancer-related deaths worldwide and the most common lung cancer subtype is lung adenocarcinoma (LUAD). Frequently mutated genes involve activating mutations in KRAS and loss of function mutations in TP53. LUADs primarily ...

Elucidating and modulating regulatory pathways so as to reprogram the immunosuppressive tumor microenvironment for therapeutic benefit

Agnieszka Alicja Chryplewicz

Glioblastoma (GBM) is the most frequent and highly malignant form of brain cancer. New therapeutic regimens are urgently needed as GBM patients present with a minimal response to currently-approved therapies. The goal of this project is to identify new the ...

Mechanism of KRAS-driven T cell infiltration in colorectal cancer

Amber Dawn Bowler

Colorectal cancer is the second-leading cause of cancer death worldwide. Early-stage disease can be detected with preventative medical screening and is treatable with surgical resection. Sixty-percent of patients, however, are diagnosed with advanced-stage ...

Hyperthermic intrathoracic chemotherapy to control malignant pleural mesothelioma

Yameng Hao

OBJECTIVE: Malignant pleural mesothelioma (MPM) is a rare disease that has a poor response to conventional therapy. Hyperthermic intrathoracic chemotherapy (HITOC), a treatment combining fever-range hyperthermia with intrapleural cisplatin chemotherapy, ha ...

Novel quantitative bioengineered tools to track human bone marrow niche cellular constituents in health and disease

Rita Sarkis

Acute leukemia has a high mortality rate of approximately 50%, and current methods are not effective in predicting disease progression and relapse. To improve our understanding of hematopoiesis and develop new markers for predicting disease relapse in dead ...

Optimized Modeling of Metastatic Triple-Negative Invasive Lobular Breast Carcinoma

Cathrin Brisken, Georgios Sflomos, Laura Battista

Simple Summary Invasive lobular carcinoma (ILC) is the second most common histologic subtype of breast cancer and is often detected at an advanced stage. Up to 30% of ILC cases relapse and present a challenge for treatment. Unfortunately, there are few mod ...

BCG hydrogel promotes CTSS-mediated antigen processing and presentation, thereby suppressing metastasis and prolonging survival in melanoma

Li Tang, Bing Feng

Background The use of intralesional Mycobacterium bovis BCG (intralesional live BCG) for the treatment of metastatic melanoma resulted in regression of directly injected, and occasionally of distal lesions. However, intralesional-BCG is less effective in p ...

The role of eosinophils in breast cancer

Luisa Spisak

Eosinophils are granulocytes and belong to the innate arm of immunity. Eosinophils can be in different basal or activation states and depending on which type of activation is applied, they exert different effector functions. These multi-functional cells ha ...

Aberrant hyperexpression of the RNA binding protein FMRP in tumors mediates immune evasion

Douglas Hanahan, Nadine Fournier, Mélanie Louise Tichet, Krisztian Homicsko, Agnieszka Alicja Chryplewicz, Mohammad Sadegh Saghafinia, Yuqing Xie, Dalya Ataca, Qiqun Zeng, Jeremy Gilles Louis Guillot, Simge Yücel

Many human cancers manifest the capability to circumvent attack by the adaptive immune system. In this work, we identified a component of immune evasion that involves frequent up-regulation of fragile X mental retardation protein (FMRP) in solid tumors. FM ...

RNA sequencing-based single sample predictors of molecular subtype and risk of recurrence for clinical assessment of early-stage breast cancer

Cathrin Brisken, Rachel Marcone, Ayyakkannu Ayyanan

Multigene assays for molecular subtypes and biomarkers can aid management of early invasive breast cancer. Using RNA-sequencing we aimed to develop single-sample predictor (SSP) models for clinical markers, subtypes, and risk of recurrence (ROR). A cohort ...

Non-genomic activation of the AKT-mTOR pathway by the mitochondrial stress response in thyroid cancer

Johan Auwerx, Kristina Schoonjans, Dongryeol Ryu

Cancer progression is associated with metabolic reprogramming and causes significant intracellular stress; however, the mechanisms that link cellular stress and growth signalling are not fully understood. Here, we identified a mechanism that couples the mi ...

An autonomous microfluidic device for identification and analysis of individual clinically-relevant mammalian cells

Fabien Louis Claude Robert Jammes

Cancer represents one of the major public health challenges worldwide, representing more than 25% of all deaths in the European Union in 2014. It affects a large and growing part of the general population, with the National Cancer Institute (NCI) estimatin ...

Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING

George Coukos, Christian Iseli, Alexandre Harari, Alizée Jéléna Grimm, Julien Dorier, Mauro Delorenzi

In this study, we investigate mechanisms leading to inflammation and immunoreactivity in ovarian tumors with homologous recombination deficiency (HRD). BRCA1 loss is found to lead to transcriptional reprogramming in tumor cells and cell-intrinsic inflammat ...

Intraductal xenografts model estrogen receptor-positive (ER+) breast cancer dormancy and reveal a critical role for epithelial-mesenchymal transition (EMT) in its establishment

Patrik Aouad

Compared to estrogen receptor-negative (ER-) breast cancer (BC), ER+ BC often manifests with a latent disease that recurs decades after initial diagnosis. The mechanisms governing dormancy and distant recurrence of ER+ tumors remain elusive due to the lack ...

Standardized intraoperative 5-ALA photodynamic therapy for newly diagnosed glioblastoma patients: a preliminary analysis of the INDYGO clinical trial

Constantin Tuleasca

Purpose Glioblastoma (GBM) is the most aggressive malignant primary brain tumor. The unfavorable prognosis despite maximal therapy relates to high propensity for recurrence. Thus, overall survival (OS) is quite limited and local failure remains the fundame ...

In vivo detection of gamma-glutamyl-transferase up-regulation in glioma using hyperpolarized gamma-glutamyl-[1-C-13]glycine

Hikari Ananda Infinity Yoshihara

Glutathione (GSH) is often upregulated in cancer, where it serves to mitigate oxidative stress. gamma-glutamyl-transferase (GGT) is a key enzyme in GSH homeostasis, and compared to normal brain its expression is elevated in tumors, including in primary gli ...
