Sjögren's syndrome and psoriasis: a two-sample Mendelian randomization study.

Primary Sjögren's Syndrome (PSS) and psoriasis are frequently observed to co-occur in clinical settings. However, the causal associations and underlying mechanisms between PSS and psoriasis remain poorly defined. In this study, we conducted bidirectional MR analysis to explore the causal relationship between PSS and psoriasis using four MR methods: inversevariance weighted, MR-Egger regression, weighted median, and weighted mode.

The Specifically Androgen-Regulated Gene (SARG) Promotes Papillary Thyroid Carcinoma (PTC) Lymphatic Metastasis Through Vascular Endothelial Growth Factor C (VEGF-C) and VEGF Receptor 3 (VEGFR-3) Axis.

The papillary thyroid carcinoma (PTC) metastasizes through lymphatic spread, but the follicular thyroid cancer (FTC) metastasis occurs by following hematogenous spread. To date, the molecular mechanism underlying different metastatic routes between PTC and FTC is still unclear. Here, we showed that specifically androgen-regulated gene (SARG) was significantly up-regulated in PTC, while obviously down-regulated in FTC through analyzing the Gene Expression Omnibus (GEO) database.
