Mitochondria‐associated membranes (MAMs): molecular organization, cellular functions, and their role in health and disease

FEBS Open Bio, EarlyView.
Mitochondria‐associated membranes (MAMs) are contact sites between the endoplasmic reticulum and mitochondria that regulate calcium signaling, lipid metabolism, autophagy, and stress responses. This review outlines their molecular organization, roles in cellular homeostasis, and how dysfunction drives neurodegeneration, metabolic disease, cancer, and ...

Molecular determinants of signal transduction in tropomyosin receptor kinases

FEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Cerebrovascular stiffness and flow dynamics in the presence of amyloid and tau biomarkers

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2021
Introduction This work investigated the relationship between cerebrovascular disease (CVD) markers and Alzheimer's disease (AD) biomarkers of amyloid beta deposition, and neurofibrillary tau tangles in subjects spanning the AD clinical spectrum.

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, EarlyView.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Characterizing biomarker features of cognitively normal individuals with ventriculomegaly

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2018
Introduction The clinical significance of ventriculomegaly in cognitively normal elderly individuals remains unclear. Methods We selected cognitively normal individuals (n = 425) from the Alzheimer's Disease Neuroimaging Initiative database and ...

Functional Connectivity Associations With Markers of Disease Progression in GRN Pathogenic Variant Carriers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autosomal dominant progranulin (GRN) pathogenic variants are a genetic cause of frontotemporal lobar degeneration. Though clinical trials for GRN‐related therapies are underway, there is an unmet need for biomarkers that can predict symptom onset and track disease progression.

Association between BrainAGE and Alzheimer's disease biomarkers

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION The brain age gap estimation (BrainAGE) method uses a machine learning model to generate an age estimate from structural magnetic resonance imaging (MRI) scans. The goal was to study the association of brain age with Alzheimer's disease (AD)

Quick assessment for systematic test statistic inflation/deflation due to null model misspecifications in genome-wide environment interaction studies.

PLoS ONE, 2019
Gene-environment (GxE) interaction is one potential explanation for the missing heritability problem. A popular approach to genome-wide environment interaction studies (GWEIS) is based on regression models involving interactions between genetic variants ...

Insulin resistance is related to cognitive decline but not change in CSF biomarkers of Alzheimer's disease in non‐demented adults

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2021
Introduction We investigated whether insulin resistance (IR) was associated with longitudinal age‐related change in cognition and biomarkers of Alzheimer's disease (AD) pathology and neurodegeneration in middle‐aged and older adults who were non‐demented
