Pathogenic Mechanisms of Collagen TypeⅦA1 (COL7A1) and Transporter Protein Transport and Golgi Organization 1 (TANGO1) in Rheumatoid Arthritis: A New Therapeutic Target

Rheumatoid arthritis (RA) is an autoimmune disorder causing chronic inflammation primarily due to collagen regulation and transport imbalances. Collagen VII A1(COL7A1), a major component of anchoring fibrils, regulates inflammation via interacting with its transporter protein Transport and Golgi org...

description Rheumatoid arthritis (RA) is an autoimmune disorder causing chronic inflammation primarily due to collagen regulation and transport imbalances. Collagen VII A1(COL7A1), a major component of anchoring fibrils, regulates inflammation via interacting with its transporter protein Transport and Golgi organization 2 homologs (TANGO1). The study revealed a significant increase in COL7A1 levels in both the plasma and PBMCs of RA patients. Additionally, a positive correlation between COL7A1 and ACCPA (anti-cyclic citrullinated peptide antibody) levels was observed among RA patients. TANGO1 mRNA expression was also found to be elevated in PBMCs. The knockdown of COL7A1 in RA synoviocytes using siRNA affected the expression of TANGO1 and inflammatory genes. Western blot analysis showed that COL7A1 si-RNA in TNF-α-induced SW982 cells reduced the expression of COL7A1, TANGO1, and NF-kBp65. The mRNA expression of inflammatory genes TNF-α, NF-kB p65, and IL-6 simultaneously decreased after the knockdown of COL7A1, as measured by qRT-PCR. An in silico analysis found 20 common interacting proteins of COL7A1 and TANGO1, with pathway enrichment analysis linking them to antigen presentation, class I and II MHC, and adaptive immunity pathways in RA. Among the common proteins, The DisGeNET database depicted that COL1A1, MIA3, SERPINH1, and GORASP1 are directly linked to RA. The molecular docking analysis of COL7A1 and TANGO1 revealed strong interaction with a −1013.4 energy-weighted score. Common RA-used drugs such as Adalimumab, Golimumab, and Infliximab were found to inhibit the interaction between COL7A1 and TANGO1, which can further impede the transport of COL7A1 from ER exit sites, indicating COL7A1 and TANGO1 as potential therapeutic targets to diminish RA progression.
