Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Using Causal Effect Networks to Analyze Different Arctic Drivers of Midlatitude Winter Circulation

open access: yes, 2016
In recent years, the Northern Hemisphere midlatitudes have suffered from severe winters like the extreme 2012/13 winter in the eastern United States.

Evidence of a Causal Effect of Estradiol on Fracture Risk in Men

open access: yesJournal of Clinical Endocrinology and Metabolism, 2018
Context Observational studies indicate that serum estradiol (E2) is more strongly associated with bone mineral density (BMD) than serum testosterone (T) is, whereas both E2 and T associate with fracture risk in men.

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Causal Effect of Plasminogen Activator Inhibitor Type 1 on Coronary Heart Disease

open access: yesJournal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2017
Background Plasminogen activator inhibitor type 1 (PAI‐1) plays an essential role in the fibrinolysis system and thrombosis. Population studies have reported that blood PAI‐1 levels are associated with increased risk of coronary heart disease (CHD ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Directed causal effect with PCMCI in hyperscanning EEG time series

open access: yesFrontiers in Neuroscience
Social activities are likely to cause effects or reactivity in the brains of the people involved in collaborative social situations. This study assesses a new method, Tigramite, for time domain analysis of directed causality between the prefrontal cortex

Mendelian randomization shows a causal effect of low vitamin D on multiple sclerosis risk

open access: yesNeurology: Genetics, 2016
Objective: We sought to estimate the causal effect of low serum 25(OH)D on multiple sclerosis (MS) susceptibility that is not confounded by environmental or lifestyle factors or subject to reverse causality. Methods: We conducted mendelian randomization (

Brucella NyxA and NyxB dimerization enhances effector function during infection

open access: yesFEBS Letters, EarlyView.
Brucella abortus thrives inside cells thanks to the translocation of effector proteins that fine‐tune cellular functions. NyxA and NyxB are two effectors that destabilize the nucleolar localization of their host target, SENP3. We show that the Nyx proteins directly interact with each other and that their dimerization is essential for their function ...

Identification and Estimation of Causal Mechanisms and Net Effects of a Treatment under Unconfoundedness [PDF]

open access: yes
An important goal when analyzing the causal effect of a treatment on an outcome is to understand the mechanisms through which the treatment causally works.
