Addressing the credibility crisis in Mendelian randomization

BMC Medicine
Background Genome-wide association studies have enabled Mendelian randomization analyses to be performed at an industrial scale. Two-sample summary data Mendelian randomization analyses can be performed using publicly available data by anyone who has ...

Mendelian randomization for studying the effects of perturbing drug targets [version 2; peer review: 2 approved, 1 approved with reservations]

Wellcome Open Research, 2021
Drugs whose targets have genetic evidence to support efficacy and safety are more likely to be approved after clinical development. In this paper, we provide an overview of how natural sequence variation in the genes that encode drug targets can be used ...

Joint analysis of SNP and gene expression data in genetic association studies of complex diseases [PDF]

, 2014
Genetic association studies have been a popular approach for assessing the association between common Single Nucleotide Polymorphisms (SNPs) and complex diseases.

Introduction to Mendelian randomization

Annals of Clinical Epidemiology
Mendelian randomization (MR), i.e. instrumental variable analysis using genetic instruments, is an approach that incorporates population genetics to improve causal inference. Given that genetics are randomly allocated at conception, this resembles the randomization process in randomized controlled trials and hence is more resistant to unobserved ...

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

Advanced Science, EarlyView.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.

Genetic markers as instrumental variables: an application to child fat mass and academic achievement [PDF]

The use of genetic markers as instrumental variables (IV) is receiving increasing attention from economists. This paper examines the conditions that need to be met for genetic variants to be used as instruments.

Role of circulating polyunsaturated fatty acids on cardiovascular diseases risk: analysis using Mendelian randomization and fatty acid genetic association data from over 114,000 UK Biobank participants

BMC Medicine, 2022
Background Despite early interest in the health effects of polyunsaturated fatty acids (PUFA), there is still substantial controversy and uncertainty on the evidence linking PUFA to cardiovascular diseases (CVDs).

Outlier Detection in Mendelian Randomization. [PDF]

Stat Med
ABSTRACT Mendelian randomization (MR) uses genetic variants as instrumental variables to infer causal effects of exposures on an outcome. One key assumption of MR is that the genetic variants used as instrumental variables are independent of the outcome conditional on the risk factor and unobserved confounders.

Microglial Feimin Alleviates Cognitive Impairment in High‐Fat Diet‐Fed Mice

Advanced Science, EarlyView.
Microglial feimin deletion exacerbates lipotoxicity‐induced neuroinflammation and cognitive decline. In both in vitro and in vivo models, loss of feimin aggravated lipid droplet accumulation, IL‐1β/IL‐6 release, and neuronal injury through the PI3K–AKT–mTOR pathway, ultimately leading to severe neuronal apoptosis and cognitive impairment under high‐fat

Causal relevance of blood lipid fractions in the development of carotid atherosclerosis: Mendelian randomization analysis. [PDF]

, 2013
BACKGROUND: Carotid intima-media thickness (CIMT), a subclinical measure of atherosclerosis, is associated with risk of coronary heart disease events. Statins reduce progression of CIMT and coronary heart disease risk in proportion to the reduction in ...
