ABSTRACT
BACKGROUND:
Previous studies have showed thatTougu XiaotongCapsule (TGXTC) exertsbetter effects on osteoarthritis, byregulatingRho/Rock signaling pathway, inhibitingsignal transduction of chondrocyte mitochondrial apoptosis pathway,varyingthe rate and pattern of subchondral bone remodeling and improving the arrangement of subchondral bone colagen fibers and calcium-phosphate crystalization.OBJECTIVE:
To observe the effects of the serum containing TGXTC and itsdisassembled recipeson chondrocytedegenerationof ratsviaWnt/β-cateninsignal pathway, and to explore the maintherapeutic method forosteoarthritis in theTGXTC.METHODS:
FortySprague-Dawley rats were randomlyassigned to receivethe treatment ofTGXTC,Bushen Rougan(BSRG),Huoxue Qufeng(HXQF) and normal saline, respectively, according tothe dose conversion methods ofanimaltoanimal and animaltohuman. Thenvarious drug-containing serums wereprepared for thefolowingcelular experiment.After culture and passage, chondrocytesfromSprague-Dawley ratsat passage 3 were divided into five groups blank control, model, TGXTC, BSRG, HXQF groups. Cels in the latter four groups wereculturedin appropriate drug-containing serums(normal salineserumfor the model group) for 72 hours, folowing intervention with interleukin-1β for 24 hours.Cels in the blank control group were cultured innormal saline serum.Afterwards, cels in al the five groups were colected for detecting expression ofWnt 4, β-cateninandmatrix metaloproteinase 13at mRNA and proteinlevels using real-time PCR and western blot assay, respectively. RESULTS ANDCONCLUSION:
Compared with theblank control group, the expressionof Wnt 4,β-catenin, matrix metaloproteinase 13 wassignificantly increasedin the model group. Compared with the model group, the expression of Wnt 4, β-catenin, matrix metaloproteinase 13 in the TGXTC, BSRG and HXQF groups were decreasedsignificantly, sequenced as TGXTC group
