The review was enriched by the inclusion of a new case: a 60-year-old woman who developed anti-MDA5-positive dermatomyositis two weeks after receiving her fourth dose of the BNT162b2 (Pfizer/BioNTech) vaccine. Treatment with oral prednisone, intravenous alprostadil, and the Janus kinase inhibitor tofacitinib resulted in marked clinical improvement. This case, together with the literature review, illustrates both typical and atypical presentations of vaccine-associated anti-MDA5 DM, highlights diagnostic challenges without lung involvement, and suggests JAK inhibition as a potential therapeutic option, contributing to a more comprehensive understanding of post-vaccination dermatomyositis.

IFIH1 (Interferon Induced With Helicase C Domain 1)
In a castrated PC-3 xenograft model, PLP (400 mg/kg/day) suppressed tumor volume growth by 91.7% and tumor weight growth by 78.0% compared with the control group, showing efficacy comparable to abiraterone/prednisone without hepatorenal toxicity...Integrative transcriptomic and multi-omics analyses revealed coordinated downregulation of phosphatidylinositol 3-kinase-protein kinase B-mechanistic target of rapamycin signaling and upregulation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α). Functional validation showed that overexpression of phosphoinositide-3-kinase regulatory subunit 1 rescued PLP-induced tumor suppression, whereas knockdown of PGC-1α abolished its antioxidative and antiproliferative effects, indicating that both pathways are critically involved. These findings suggest that PLP combats CRPC by simultaneously inhibiting oncogenic signaling and mitigating oxidative stress, positioning it as a promising natural therapeutic candidate for CRPC.
