Our findings suggest that extracellular PPM1A may contribute to the pathogenesis of RA by functioning as a damage-associated molecular pattern (DAMP) to induce inflammation.
This study comprehensively identified PBMC-expressed miRNAs along with corresponding regulatory networks significant for RA and discovered miR-99b-5p as a novel post-transcriptional mediator involved in RA pathogenesis.
The infiltration of macrophages, TLR9, autophagy proteins (TFEB and LC3) and inflammatory cytokines increased in the periodontitis-with-RA group and was reduced by the inhibition of Ctsk in the periodontal region.
In addition, SPR inhibition increases urinary sepiapterin levels, indicating the potential of this measurement as a noninvasive biomarker of target engagement of SPR inhibitors, such as sulfasalazine, a disease-modifying antirheumatic drug that is currently used as a first-line treatment for rheumatoid arthritis.
Significantly more CD4+ T cells from SpA patients produced TNF-α, IFNγ and IL-17A in response to recombinant CD74 than patients with rheumatoid arthritis or healthy blood donors.
Furthermore, other reported AhR antagonists also upregulate utrophin, showing that this pathway, which is currently being explored in other clinical applications including oncology and rheumatoid arthritis, could also be exploited in future DMD therapies.
Although no significant differences in serum FGF-23 levels between patients and controls were found (p=0.43), FGF-23 levels were positively associated with low-density lipoprotein (LDL-c) level (p<0.05) and smoking (p=0.008) in patients with RA.
The present results suggest that RAS-related components in RA and OA, including renin, ACE, angiotensin type 1 and type 2 receptors, are associated with increased expression of VEGF and play an important role in angiogenesis.
The membrane fraction from <i>MYL4</i>-/- hESC-atrial cells demonstrated increased phospho-Cx43 which was further accentuated by retinoic acid (RA) treatment and by the presence of risk alleles at the Pitx2 locus.
Collectively, our results demonstrated a new mechanism of SDC4 in initiating the inflammation and inhibiting the apoptosis of RA-FLSs and that a potential target for the diagnosis and treatment of RA in the clinic might be developed.
Of the 13 deregulated innate genes (TLR2, TLR3, TLR4, TLR5, TLR8, TLR10, IL1B, IL1RN, IL18, IL18R1, IL1RAP, and SIGIRR/IL1R8) associated with RA, TLR10 and IL1RAP are being reported for the first time.
This study showed that inflammatory cytokines IL-17A can upregulate the mRNA expression level and drug efflux function of P-gp on lymphocytes in RA patients through TAK1, in a concentrate dependent manner, contributing to RA drug resistance.
Tylophorine-based compounds are therapeutic in rheumatoid arthritis by targeting the caprin-1 ribonucleoprotein complex and inhibiting expression of associated c-Myc and HIF-1α.
Formaldehyde-fixed synovial tissue sections, from patients with RA (N = 6) and OA (N = 6) undergoing total hip arthroplasty, were deparaffinized and immunostained with monoclonal antibodies against MFAP4.Elastin was detected using ElastiKit.
Subsequently, the role and potential underlying mechanisms of TGR5 in the PBMCs of patients with RA and mice with collagen II‑induced arthritis (CIA) were investigated.
