Figure Lengend Snippet: Significant Ups genes in the acetabular cartilage of the rats with DDH, as determined by mRNA-seq analysis. (A) Neonatal rats were subjected to straight-leg swaddling for 10 days. A total of 4 weeks later, (a) morphology, (b) H&E staining and (c) SO/FG staining were assessed in the hip joints of the rats. (B) Immunohistochemical staining and (E) semi-quantitative analysis of COL2A1 in the acetabular cartilage of the 4-week-old control rats and rats with DDH. (C) Relative gene expression levels of COL2A1, IL-1β and IL-6 in the acetabular cartilage of the 4-week-old control rats and rats with DDH, as determined by reverse transcription-quantitative PCR. (D) Levels of IL-6 in the supernatants of acetabular cartilage from the 4-week-old rats with DDH, as determined by ELISA. (F) Significant Ups in the acetabular cartilage of rats with DDH were identified by mRNA-seq analysis with the screening criteria of log 2 FC >4 and P.adj<0.01. Principal component analysis results and a heatmap of these significant Ups are shown. (G) GO enrichment analysis of significant Ups in the acetabular cartilage of the rats with DDH. Data are presented as the mean ± SD. *** P<0.001. (C-E) Representative results of four independent experiments are shown. Ups, upregulated genes; BP, biological process; CC, cellular component; COL2A1, type II collagen; DDH, developmental dysplasia of the hip; FC, fold change; GO, Gene Ontology; H&E, hematoxylin and eosin; IHC, immunohistochemistry; IL, interleukin; IOD, integrated optical density; MF, molecular function; mRNA-seq, mRNA sequencing; SO/FG, Safranin O/Fast Green.

Article Snippet: Protein concentrations were measured using a BCA assay kit (cat. no. PK10026; Wuhan Sanying Biotechnology), and the levels of TNF-α and IL-6 in the tissue homogenates and cell supernatants were measured using the Rat TNF-α ELISA Kit (cat. no. EK382; Multi Sciences Biotech) and Rat IL-6 ELISA Kit (cat. no. EK306; Multi Sciences Biotech), according to the manufacturers' instructions.

Figure Lengend Snippet: DUSP26 overexpression alleviates IL-1β-induced chondrocyte injury. Rat DUSP26 overexpression adenovirus was constructed and used to infect chondrocytes. After 24 h, the chondrocytes were subjected to 10 ng/ml IL-1β. (A) Expression levels of COL2A1 and COL1A1 in the chondrocytes were detected by RT-qPCR and western blotting. (B) Relative mRNA expression levels of TNF-α and IL-6 in the chondrocytes were determined by RT-qPCR. (C) Levels of TNF-α and IL-6 in the supernatants of the chondrocytes were determined by ELISA. Two adenovirus-mediated shRNAs against rat DUSP26 were constructed and used to infect chondrocytes. After 24 h, the chondrocytes were subjected to 10 ng/ml IL-1β. (D) Expression levels of COL2A1 and COL1A1 in the chondrocytes were evaluated by RT-qPCR and western blotting. (E) Relative mRNA expression levels of TNF-α and IL-6 in the chondrocytes were determined by RT-qPCR. (F) Levels of TNF-α and IL-6 in the supernatants of the chondrocytes were detected by ELISA. Data are presented as the mean ± SD. * P<0.05, ** P<0.01 and *** P<0.001. Representative results of three independent experiments are shown. COL1A1, type I collagen; COL2A1, type II collagen; EP, empty adenoviral vector; DUSP26, dual-specificity phosphatase 26; IL, interleukin; NC, negative control; RT-qPCR, reverse transcription-quantitative PCR; sh, short hairpin.
