Abstract
Objective: Alopecia areata (AA) is an autoimmune skin disease. Observational studies have reported an association between AA and cancer. However, the causal relationship between AA and cancer has not been reported. We employed a two-sample Mendelian randomization (MR) study to assess the causality between AA and 17 subtypes of cancers.
Methods: We employed a two-sample Mendelian randomization (MR) study to assess the causality between AA and 17 subtypes of cancers. AA and cancers' association genome-wide association study (GWAS) data were collected. The inverse variance weighted (IVW) method was utilized as the principal method in our Mendelian randomization (MR) study, with additional use of the MR-Egger, weighted median, simple mode, and weighted mode methods. After that, we explored the underlying biological mechanisms by Bioinformatic Analysis.
Results: According to our MR analysis, AA has a causal relationship with hepatic bile duct cancer (HBDC, (odds ratio [OR] = 0.944, 95% confidence interval [CI] = 0.896-0.994, P-value = 0.030) and colorectal cancer (CRC, OR = 0.981, 95% CI = 0.963-0.999, P-value = 0.046). AA could decrease the risk of HBDC and CRC. No causal link between AA and other subtypes of cancers was observed. No heterogeneity or pleiotropy was observed. Furthermore, disease-related genes were obtained, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis results showed that the set of genes associated with immunity-inflammatory signaling pathway.
Conclusion: This study provided new evidence of the relationship between AA with HBDC and CRC. AA may play a protective role in both HBDC and CRC progression. This could provide newer avenues for research in search of treatment for HBDC and CRC.
期刊介绍:
Clinical, Cosmetic and Investigational Dermatology is an international, peer-reviewed, open access journal that focuses on the latest clinical and experimental research in all aspects of skin disease and cosmetic interventions. Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal.
Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest.
The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care.
All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
