Annona cherimola Seed Extract Activates Extrinsic and Intrinsic Apoptotic Pathways in Leukemic Cells

Rita Sarkis

Annona cherimola Mill is a large green fruit with black seeds widely known to possess toxic properties due to the presence of Annonaceous acetogenins. The present study investigates the anti-cancer properties of an Annona cherimola Mill ethanolic seed extr ...

A cell fitness selection model for neuronal survival during development

Gioele La Manno

Developmental cell death plays an important role in the construction of functional neural circuits. In vertebrates, the canonical view proposes a selection of the surviving neurons through stochastic competition for target-derived neurotrophic signals, imp ...

Drug Repurposing Approach Identifies a Synergistic Drug Combination of an Antifungal Agent and an Experimental Organometallic Drug for Melanoma Treatment

Paul Joseph Dyson, Olivier Pierre Zava, Tina Riedel

By screening a drug library comprising FDA approved compounds, we discovered a potent interaction between the antifungal agent haloprogin and the experimental organometallic drug RAPTA-T, to synergistically induce cancer cell killing. The combination of th ...

An essential thioredoxin is involved in the control of the cell cycle in the bacterium Caulobacter crescentus

Camille Véronique Bernadette Goemans

Thioredoxins (Trxs) are antioxidant proteins that are conserved among all species. These proteins have been extensively studied and perform reducing reactions on a broad range of substrates. Here, we identified Caulobacter crescentus Trx1 (CCNA_03653; CcTr ...

Three branches to rule them all? UPR signalling in response to chemically versus misfolded proteins-induced ER stress

Maurizio Molinari

Study of the unfolded protein responses (UPR) is mainly addressed by challenging eukaryotic cells with chemical compounds that impair calcium, redox or glycan homeostasis. These dramatically alter the endoplasmic reticulum (ER) environment and function, bu ...

Structure and Analysis of R1 and R2 Pyocin Receptor-Binding Fibers

Petr Leiman, Mikhail Shneyder, Sergii Buth

The R-type pyocins are high-molecular weight bacteriocins produced by some strains of Pseudomonas aeruginosa to specifically kill other strains of the same species. Structurally, the R-type pyocins are similar to simple contractile tails, such as those of ...

Dual action of L-Lactate on the activity of NR2B-containing NMDA receptors: from potentiation to neuroprotection

Pierre Magistretti, Pierre Marquet, Igor Allaman, Pascal Jourdain

L-Lactate is a positive modulator of NMDAR-mediated signaling resulting in plasticity gene induction and memory consolidation. However, L-Lactate is also able to protect neurons against excito-toxic NMDAR activity, an indication of a mitigating action of L ...

Dielectrophoresis as a single cell characterization method for bacteria

Philippe Renaud, John McKinney, Neeraj Dhar, Thomas Michael Braschler, Ana Valero

Real-time, quantitative characterization of cells at single-cell resolution, particularly while maintain- ing their intrinsic properties and without affecting cellular processes, is of primary importance in modern biological assays. Dielectrophoresis is a ...

Remodeling of peripheral nerve ensheathment during the larval-to-adult transition in Drosophila

Soumya Banerjee

Over the course of a 4-day period of metamorphosis, the Drosophila larval nervous system is remodeled to prepare for adult-specific behaviors. One example is the reorganization of peripheral nerves in the abdomen, where five pairs of abdominal nerves (A4-A ...

Stepwise growth of gold coated cancer targeting carbon nanotubes for the precise delivery of doxorubicin combined with photothermal therapy

Paul Joseph Dyson, Zhaofu Fei

Combining doxorubicin with thermal therapy in the clinic has led to startling results in the treatment of problematic cancers. Here, we describe a multimo dal multi-walled carbon nanotube material that combines tumor targeting, doxorubicin delivery, and ph ...

Functional Characterization of Nucleoid Associated Proteins Acting as Global Transcription Factors in Mycobacterium tuberculosis

Nina Theres Odermatt

The fatal lung disease tuberculosis is caused by the airborne Mycobacterium tuberculosis, a versatile pathogen adapted to rapidly changing environments. Instead of being eradicated by phagocytic cells of its human host, bacilli tune macrophages to support ...

Phosphorylation of α-synuclein is crucial in compensating for proteasomal dysfunction

Hilal Lashuel

α-Synuclein can be degraded by both the ubiquitin-proteasomal system and the chaperone-lysosomal system. However, the switching mechanism between the two pathways is not clearly understood. In our study, we investigated the mutual association between the b ...
