Preomic profile of BxPC-3 cells after treatment with BRC4

Andrea Cavalli

BRCA2 and RAD51 are two proteins that play a central role in homologous recombination (HR) and DNA double strand break (DSB) repair. BRCA2 assists RAD51 fibrillation and defibrillation through binding with its eight BRC repeats, with BRC4 being one of the ...

Mutation-Attention (MuAt): deep representation learning of somatic mutations for tumour typing and subtyping

Sebastian Martin Waszak

Background: Cancer genome sequencing enables accurate classification of tumours and tumour subtypes. However, prediction performance is still limited using exome-only sequencing and for tumour types with low somatic mutation burden such as many paediatri ...

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 ...

PRDX1 Counteracts Catastrophic Telomeric Cleavage Events That Are Triggered by DNA Repair Activities Post Oxidative Damage

Joachim Lingner, Wareed Ahmed

Telomeres are prone to damage inflicted by reactive oxygen species (ROS). Oxidized telomeric DNA and nucleotide substrates inhibit telomerase, causing telomere shortening. In addition, ROS can induce telomeric single-strand DNA breaks (SSBs). The peroxired ...

Dopaminergic neurodegeneration induced by Parkinson's disease-linked G2019S LRRK2 is dependent on kinase and GTPase activity

Xi Chen, Elpida Tsika

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of late-onset, autosomal-dominant familial Parkinson's disease (PD). LRRK2 functions as both a kinase and GTPase, and PD-linked mutations are known to influence both enzymatic acti ...

Somatic Mitochondrial DNA Point Mutations Used as Biomarkers to Demonstrate Genomic Heterogeneity in Primary Prostate Cancer

Paul Refinetti

Primary prostate tumor heterogeneity is poorly understood, leaving research efforts with challenges regarding the initiation and advancement of the disease. The growth of tumor cells is accompanied by mutations in nuclear and in mitochondrial genomes. Thus ...

Notch Signaling - a Booster of Chronic Lymphocytic Leukemia During Initiation and Disease Progression

Delphine Maude Tardivon

Chronic lymphocytic leukemia (CLL) is a B cell malignancy and represents the most common leukemia in adults within the Western world. This disease mainly affects the elderly, with a median age of diagnosis over 70. The disease course is highly variable amo ...

Cellular responses of BRCA1-defective HCC1937 breast cancer cells induced by the antimetastasis ruthenium(II) arene compound RAPTA-T

Paul Joseph Dyson

An organometallic ruthenium(II) arene compound, Ru((6)-toluene)(PTA)Cl-2 (PTA=1,3,5-triaza-7-phosphaadamantane), termed RAPTA-T, exerts promising antimetastatic properties. In this study, the effects of RAPTA-T on BRCA1-defective HCC1937 breast cancer cell ...

Clinical and Genetic Findings of Autosomal Recessive Bestrophinopathy (ARB)

Daniel Francis Schorderet

Mutations in BEST1 cause several phenotypes including autosomal dominant (AD) Best vitelliform macular dystrophy type 2 (BVMD), AD vitreo-retino-choroidopathy (ADVIRC), and retinitis pigmentosa-50 (RP50). A rare subtype of Bestrophinopathy exists with bial ...

Predicting the Occurrence of Variants in RAG1 and RAG2

Jacques Fellay, Flavia Aurelia Shoko Hodel, Dylan Lawless

While widespread genome sequencing ushers in a new era of preventive medicine, the tools for predictive genomics are still lacking. Time and resource limitations mean that human diseases remain uncharacterized because of an inability to predict clinically ...

Preventive chemotherapy to control soil-transmitted helminthiasis averted more than 500 000 DALYs in 2015

Background: Preventive chemotherapy (PC), the large-scale administration of anthelminthics, is recommended by the World Health Organization (WHO) for the control of soil-transmitted helminthiasis (STH). Since 2010, donated anthelminthics for STH have boost ...

Properties of LINE-1 proteins and repeat element expression in the context of amyotrophic lateral sclerosis

Didier Trono, Priscilla Turelli, Evaristo Jose Planet Letschert

BackgroundAmyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease involving loss of motor neurons and having no known cure and uncertain etiology. Several studies have drawn connections between altered retrotransposon expression and ALS. C ...

Biochemical and biophysical characterization of ruthenation of BRCA1 RING protein by RAPTA complexes and its E3 ubiquitin ligase activity

Paul Joseph Dyson, Laure Menin, Luc Patiny

RAPTA compounds, ([Ru(eta(6)-arene)(PTA)Cl-2], PTA = 1,3,5-triaza-7-phosphaadamantane), have been reported to overcome drug resistance in cisplatin resistant cells. However, the exact mechanism of these complexes is still largely unexplored. In this study, ...
