ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of 2-deoxyglucose inhibiting synovial pannus of adjuvant arthritis rats and to explore its potential mechanism of inhibiting angiogenesis by investigating proliferation, migration and matrigel tube formation assay .</p><p><b>METHODS</b>The effect of 2-DG on synovial pannus was evaluated by histopathology of HE staining; HUVEC proliferation was determined by CCK-8 method; migration of FLS were determined by transwell; matrigel tube formation assay was made for assessing tube number of HUVEC; p-AMPK and Bcl-2 were detected by Western blot assay; AMPK signaling pathway in HUVEC was inhibited by compound C, which is an inhibitor of AMPK activation.</p><p><b>RESULTS</b>2-DG (200 mg/kg) obviously decreased appearance of synovial pannus ( < 0.01); , 2-DG (0.5 mmol/L and/or 5 mmol/L) obviously inhibited proliferation, migration and tube number of HUVEC ( < 0.01 or < 0.001), and its effects on HUVEC were reversed by using AMPK antagonist (Compound C); Western blot showed that 2-DG (5 mmol/L) increased expression of p-AMPK and decreased expression of Bcl-2 ( < 0.05).</p><p><b>CONCLUSIONS</b>Activating AMPK pathway and decreasing expression of Bcl-2 may the potential mechanism by which 2-DG contributes to anti-angiogenesis and effects of inhibiting proliferation, migration and tube number of HUVEC.</p>
