Nucleic Acid Programmable Protein Arrays (NAPPA) for the Discovery of Autoantibodies in Osteoarthritis.

Methods Mol Biol 2021 ;2344:181-190

Grupo de Investigación de Reumatología (GIR), Instituto de Investigación Biomédica de A Coruña (INIBIC), Complexo Hospitalario Universitario de A Coruña (CHUAC), Sergas. Universidade da Coruña (UDC), A Coruña, Spain.

Since a decade, the nucleic acid protein programmable array (NAPPA) technology has provided researchers with a high-throughput proteomic technique for deciphering immune signatures and screening for biomarkers, among other applications. In osteoarthritis (OA), the activation of proinflammatory pathways of innate immunity due to cellular stress response and cartilage degradation is now considered to be one of the pathophysiological drivers of the disease, perpetuating the catabolic process and the inflammation of the joint. Therefore, the identification of immunosignatures in OA would allow to detect autoantibodies (AAbs) as a new source of disease-specific biomarkers. Read More

The role of HIF proteins in maintaining the metabolic health of the intervertebral disc.

Nat Rev Rheumatol 2021 Jun 3. Epub 2021 Jun 3.

Graduate Program in Cell Biology and Regenerative Medicine, Thomas Jefferson University, Philadelphia, PA, USA.

The physiologically hypoxic intervertebral disc and cartilage rely on the hypoxia-inducible factor (HIF) family of transcription factors to mediate cellular responses to changes in oxygen tension. During homeostatic development, oxygen-dependent prolyl hydroxylases, circadian clock proteins and metabolic intermediates control the activities of HIF1 and HIF2 in these tissues.
