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 ...

Detecting the metabolism of individual yeast mutant strain cells when aged, stressed or treated with antioxidants with diamond magnetometry

Mayeul Sylvain Chipaux

Free radicals play a key role in the ageing process. However, free radicals are small, reactive and short lived and thus challenging to measure. We utilize a new technique called diamond magnetometry for this pur-pose. We make use of nitrogen vacancy cente ...

Three-dimensional chromatin interactions remain stable upon CAG/CTG repeat expansion

Marion Leleu, Flavia Marzetta, Ludovica Vanzan

Expanded CAG/CTG repeats underlie 13 neurological disorders, including myotonic dystrophy type 1 (DM1) and Huntington's disease (HD). Upon expansion, disease loci acquire heterochromatic characteristics, which may provoke changes to chromatin conformation ...

Enteric infection induces Lark-mediated intron retention at the 5 ' end of Drosophila genes

Bart Deplancke, Maroun Bou Sleiman, Dani Osman, Michael Vincent Frochaux

Background RNA splicing is a key post-transcriptional mechanism that generates protein diversity and contributes to the fine-tuning of gene expression, which may facilitate adaptation to environmental challenges. Here, we employ a systems approach to study ...

FasR Regulates Fatty Acid Biosynthesis and Is Essential for Virulence of Mycobacterium tuberculosis

Stewart Cole, Claudia Sala

Mycobacterium tuberculosis, the etiologic agent of human tuberculosis, is the world's leading cause of death from an infectious disease. One of the main features of this pathogen is the complex and dynamic lipid composition of the cell envelope, which adap ...

The DEAD-box RNA helicase CshA is required for fatty acid homeostasis inStaphylococcus aureus

Bianca Marie Petrignani

Staphylococcus aureusis an opportunistic pathogen that can grow in a wide array of conditions: on abiotic surfaces, on the skin, in the nose, in planktonic or biofilm forms and can cause many type of infections. Consequently,S.aureusmust be able to adapt r ...

Allele-specific gene editing prevents deafness in a model of dominant progressive hearing loss

Bernard Schneider, Paola Andrea Solanes Vega, Sofia Carmen Suzanne Spataro

Since most dominant human mutations are single nucleotide substitutions(1,2), we explored gene editing strategies to disrupt dominant mutations efficiently and selectively without affecting wild-type alleles. However, single nucleotide discrimination can b ...

A Microfluidic Platform Enables Large-Scale Single-Cell Screening to Identify Genes Involved in Bacterial Persistence

Amanda Verpoorte

Persistent cells, representing a small fraction of a bacterial population, are refractory to antibiotic therapy. It is a phenotypic transient state. The underlying mechanisms of persistence remain largely unknown, but even divergent hypotheses agree on a f ...

Inferring the age and strength of mutations evolving under positive selection

Nicky Louise Ormond

A fundamental goal of population genetics is to determine and quantify the interplay of mutation, natural selection, genetic drift and migration in shaping allelic frequency changes that underpin evolution-ary change. In this dissertation, I present comput ...

A new promoter element associated with daily time keeping in Drosophila

Felix Naef, Eric Paquet

Circadian clocks are autonomous daily timekeeping mechanisms that allow organisms to adapt to environmental rhythms as well as temporally organize biological functions. Clock-controlled timekeeping involves extensive regulation of rhythmic gene expression. ...

Genotypic, phenotypic and mechanistic insights into viruses with resistance to common water disinfectants

Qingxia Zhong

Infectious diseases caused by waterborne viruses contribute to the global disease burden. An effective barrier to prevent the discharge of waterborne viruses is a disinfection step, yet disinfection is not always efficient at inactivating viruses. This the ...

Ovary-specific depletion of the nuclear receptor Nr5a2 compromises expansion of the cumulus oophorus but not fertilization by intracytoplasmic sperm injection

Kristina Schoonjans

The orphan nuclear receptor, liver receptor homolog-1 (aka Nuclear receptor subfamily 5, Group A, Member 2 (Nr5a2)), is widely expressed in mammalian tissues, and its ovarian expression is restricted to granulosa cells of activated follicles. We employed t ...

Genetic, structural and phenotypic properties of MS2 coliphage with resistance to ClO2 disinfection

Tamar Kohn, Anna Carratala Ripolles, Petr Leiman, Virginie Bachmann, Sergey Nazarov, Qingxia Zhong, Ricardo Cesar Guerrero Ferreira

Common water disinfectants like chlorine have been reported to select for resistant viruses, yet little attention has been devoted to characterizing disinfection resistance. Here, we investigated the resistance of MS2 coliphage to inactivation by chlorine ...
