Multiple Knee Osteoarthritis-related protein targets (Multiple KOA targets)

Multiple KOA-related protein targets refers to a diverse group of proteins and signaling pathways involved in the development and progression of knee osteoarthritis (KOA). This category encompasses catabolic enzymes like matrix metalloproteinases (notably MMP-13) and aggrecanases (such as ADAMTS-5), which are responsible for the degradation of the cartilage extracellular matrix (PMC10445642). It also includes pro-inflammatory cytokines, including interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α), which mediate joint inflammation and chondrocyte dysfunction (PubMed: 33452124). Furthermore, therapeutic strategies often target signaling pathways like the Wnt/beta-catenin pathway (via CLK/DYRK inhibition) or growth factor receptors (such as FGFR3) to promote cartilage repair or prevent further damage (ScienceDaily, 2021). Because KOA is a complex, multi-tissue disease involving cartilage, subchondral bone, and synovium, modern drug development frequently explores multi-target approaches to achieve disease-modifying effects (PMC10445642). These targets are critical for the development of disease-modifying osteoarthritis drugs (DMOADs), which aim to alter the underlying pathology rather than just managing symptoms (Technology Networks, 2022).
