The role of vitamins D, B12, C, and K in modulating inflammation and disease management in rheumatoid arthritis: a comprehensive review.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder marked by joint inflammation and destruction. Recent studies emphasize the importance of vitamins D, B12, C, and K in managing RA and enhancing patient health. Vitamin D deficiency is common in RA patients and correlates with increased disease severity, indicating its potential to modulate immune responses and reduce inflammation.

Targeting Wnt/tenascin C-mediated cross talk between pancreatic cancer cells and stellate cells via activation of the metastasis suppressor NDRG1.

A major barrier to successful pancreatic cancer (PC) treatment is the surrounding stroma, which secretes growth factors/cytokines that promote PC progression. Wnt and tenascin C (TnC) are key ligands secreted by stromal pancreatic stellate cells (PSCs) that then act on PC cells in a paracrine manner to activate the oncogenic β-catenin and YAP/TAZ signaling pathways. Therefore, therapies targeting oncogenic Wnt/TnC cross talk between PC cells and PSCs constitute a promising new therapeutic approach for PC treatment.
