Publications related to Dual Targeting of the Autophagic Regulatory Circuitry in Gliomas with Repurposed Drugs Elicits Cell-Lethal Autophagy and Therapeutic Benefit

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

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 ...

Cancer cell autophagy, reprogrammed macrophages, and remodeled vasculature in glioblastoma triggers tumor immunity

Julie Laetitia Scotton, Douglas Hanahan, Ksenya Shchors, Krisztian Homicsko, Mélanie Louise Tichet, Agnieszka Alicja Chryplewicz

Glioblastoma (GBM) is poorly responsive to therapy and invariably lethal. One conceivable strategy to circumvent this intractability is to co-target distinctive mechanistic components of the disease, aiming to concomitantly disrupt multiple capabilities re ...

Highly Sensitive Detection of the Antidepressant Fluoxetine With an Extended Gate Field Effect Transistor

Mihai Adrian Ionescu, Shokoofeh Sheibani

Fluoxetine (FL) is one of the selective serotonin reuptake inhibitors, which is used as an anti-depressant, as well as anti-panic drug. In this work, a sensor for label-free recognition of trace amounts of FL is introduced, which is based on an extended ga ...

Metabolic signature in nucleus accumbens for anti-depressant-like effects of acetyl-L-carnitine

Maria del Carmen Sandi Perez, Rolf Gruetter, Antoine Timothée Cherix, Jocelin Grosse, Thomas Didier Larrieu, João Pedro de Matos Rodrigues

Emerging evidence suggests that hierarchical status provide vulnerability to develop stress-induced depression. Energy metabolic changes in the nucleus accumbens (NAc) were recently related to hierarchical status and vulnerability to develop depression-lik ...

Combinatorial targeting of angiogenesis with inducers of autophagy in the treatment of glioblastoma multiforme

Julie Laetitia Scotton

Malignant gliomas represent 80% of tumors developing in the central nervous system, with 50% being glioblastomas (GBM), the most aggressive form of the disease. The benefit from current therapies is very limited, the overall 5-year survival rate of patient ...

The HDAC inhibitor SAHA improves depressive-like behavior of CRTC1-deficient mice: Possible relevance for treatment-resistant depression

Pierre Magistretti, Jean-René Cardinaux

Major depression is a highly complex disabling psychiatric disorder affecting millions of people worldwide. Despite the availability of several classes of antidepressants, a substantial percentage of patients are unresponsive to these medications. A better ...

Involvement of the agmatinergic system in the depressive-like phenotype of the Crtc1 knockout mouse model of depression

Pierre Magistretti, Jean-René Cardinaux

Recent studies implicate the arginine-decarboxylation product agmatine in mood regulation. Agmatine has antidepressant properties in rodent models of depression, and agmatinase (Agmat), the agmatine-degrading enzyme, is upregulated in the brains of mood di ...

Involvement of autophagy in hypoxic-excitotoxic neuronal death

Nikita Rudinskiy

Neuronal autophagy is increased in numerous excitotoxic conditions including neonatal cerebral hypoxia-ischemia (HI). However, the role of this HI-induced autophagy remains unclear. To clarify this role we established an in vitro model of excitotoxicity co ...

Orphan nuclear receptor TR3 acts in autophagic cell death via mitochondrial signaling pathway

Friedrich Beermann, Rong Wu, Li Li, Yi Zhang, Jie Zhang, Qian Zhang, Ang Li, Ping Chen, Bo Zhou, Yuan Liu

Autophagy is linked to cell death, yet the associated mechanisms are largely undercharacterized. We discovered that melanoma, which is generally resistant to drug-induced apoptosis, can undergo autophagic cell death with the participation of orphan nuclear ...

Regulation of Neurotrophic Factors and Energy Metabolism by Antidepressants in Astrocytes

Jean-Luc Martin, Pierre Magistretti, Igor Allaman

There is growing evidence that astrocytes are involved in the neuropathology of major depression. In particular, decreases in glial cell density observed in the cerebral cortex of individuals with major depressive disorder are accompanied by a reduction of ...

Psychobiological Vulnerability to Stress : Behavioral Traits and Neurobiological Mechanisms

Maria del Carmen Sandi Perez, Jorge Eduardo Castro Cifuentes

Several psychobiological factors are associated with vulnerability/resilience to stress-induced depression. Emerging evidence indicates behavioral traits, such as anxiety, can be related to depression-like symptoms after exposure to chronic stress. However ...

Fluoxetine regulates the expression of neurotrophic/growth factors and glucose metabolism in astrocytes

Jean-Luc Martin, Pierre Magistretti, Igor Allaman

RATIONALE: The pharmacological actions of most antidepressants are ascribed to the modulation of serotonergic and/or noradrenergic transmission in the brain. During therapeutic treatment for major depression, fluoxetine, one of the most commonly prescribed ...

Role of the amygdala in antidepressant effects on hippocampal cell proliferation and survival and on depression-like behavior in the rat

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Jorge Eduardo Castro Cifuentes, Cristina Marquez Vega, Guillaume Poirier

The stimulation of adult hippocampal neurogenesis by antidepressants has been associated with multiple molecular pathways, but the potential influence exerted by other brain areas has received much less attention. The basolateral complex of the amygdala (B ...

Regulation of brain-derived neurotrophic factor (BDNF) in the chronic unpredictable stress rat model and the effects of chronic antidepressant treatment

Maria del Carmen Sandi Perez

Chronic unpredictable stress (CUS) is a widely used animal model of depression. The present study was undertaken to investigate behavioral, physiological and molecular effects of CUS and/or chronic antidepressant treatment (venlafaxine or imipramine) in th ...

A model for the involvement of neural cell adhesion molecules in stress-related mood disorders

Maria del Carmen Sandi Perez, Reto Bisaz

Critical interactions between genetic and environmental factors -- among which stress is one of the most potent non-genomic factors -- are involved in the development of mood disorders. Intensive work during the past decade has led to the proposal of the n ...
