AI Article Synopsis

  • Some studies suggest an increase in sunburns and cutaneous melanoma (CM) risk, but a direct cause-and-effect relationship has not been proven.
  • This study utilized a two-sample Mendelian randomization approach to investigate the potential causal link between sunburn history and CM using extensive genome-wide data.
  • The findings indicate a causal association, suggesting that a history of sunburn increases the risk of CM, particularly pointing to shared genetic factors among Caucasian, European, or British populations.

Article Abstract

Background: Some studies have reported that sunburns and cutaneous melanoma (CM) risk is increasing, but a clear causal link has yet to be established.

Methods: This current study conducted a two-sample Mendelian randomization (MR) approach to clarify the association and causality between sunburn history and CM using large-scale genome-wide association study data.

Results: The inverse-variance weighted method result showed that sunburn might be associated with the risk of CM increasing (p = 2.21 × 10, OR = 1.034, 95% CI= 1.027-1.041), causally. The MR-Egger regression, weighted median method, simple mode method, and weighted mode method results showed similar results.

Conclusion: This study offers evidence of sunburn history and increased risk of CM, and it shows that there might be common genetic basics regarding sunburns and CM susceptibility in Caucasian, European, or British ethnic groups.

This study aimed to investigate the genetic association between glioblastoma (GBM) and unsupervised deep learning-derived imaging phenotypes (UDIPs). We employed a combination of genome-wide association study (GWAS) data, single-nucleus RNA sequencing (snRNA-seq), and scPagwas (pathway-based polygenic regression framework) methods to explore the genetic links between UDIPs and GBM. Two-sample Mendelian randomization analyses were conducted to identify causal relationships between UDIPs and GBM.

Sensitivity to Environmental Stress and Adversity and Lung Cancer.

JAMA Netw Open

January 2025

Division of Cancer Epidemiology and Genetics, National Cancer Institute, National Institutes of Health, Rockville, Maryland.

Importance: Sensitivity to environmental stress and adversity may influence lung cancer risk, highlighting a critical link between psychosocial factors and cancer etiology.

Objective: To evaluate whether genetically estimated sensitivity to environmental stress and adversity is associated with lung cancer risk.

Design, Setting, And Participants: Data were obtained from a genome-wide association study identifying 37 independent genetic variants strongly associated with sensitivity to environmental stress and adversity and a cross-ancestry genome-wide meta-analysis from the International Lung Cancer Consortium.

Causal associations between immune cells and psychiatric disorders: a bidirectional mendelian randomization analysis.

Extensive researches illuminate a potential interplay between immune traits and psychiatric disorders. However, whether there is the causal relationship between the two remains an unresolved question. We conducted a two-sample bidirectional mendelian randomization by utilizing summary data of 731 immune cell traits from genome-wide association studies (GCST90001391-GCST90002121)) and 11 psychiatric disorders including attention deficit/hyperactivity disorder (ADHD), anxiety disorder, autism spectrum disorder (ASD), bipolar disorder (BIP), anorexia nervosa (AN), major depressive disorder (MDD), obsessive-compulsive disorder (OCD), Tourette syndrome (TS), post-traumatic stress disorder (PTSD), schizophrenia (SCZ), and substance use disorders (cannabis) (SUD) from the Psychiatric Genomics Consortium (PGC).

Causal associations between childhood obesity and delayed puberty or height: a bidirectional two-sample Mendelian randomization study.

J Pediatr Endocrinol Metab

January 2025

Department of Pediatric Endocrinology, School of Medicine, Shanghai Children's Hospital, Shanghai Jiao Tong University, Shanghai, China.

Objectives: Childhood obesity is thought to influence pubertal development, according to observational studies. However, the exact causal relationship remains unclear due to the complexity of factors affecting pubertal development.

Methods: To explore the association between exposure (childhood obesity) and outcome (delayed puberty, height), we utilized various methods, including inverse-variance weighted (IVW), weighted median, weighted mode, and MR Egger regression.
