Figure Lengend Snippet: Expression of several senescence-associated proteins under HS conditions at 41 °C and 45 °C for 30 min in aged HFF-1 cells. (a) Detection of protein expression levels of GORAB, AURKB, RhoC, α-N-catenin, RRM2, AURKA, and PLK1 under 41 °C and 45 °C HS. Protein expression was quantified as fold-change relative to untreated controls (set to 1), normalized to GAPDH. (b) GORAB. (c) AURKB. (d) RhoC. (e) α-N-catenin. (f) RRM2. (g) AURKA. (h) PLK1. Representative blots were cropped only to improve presentation; the corresponding full-length, uncropped blots with molecular-weight markers and the associated GAPDH loading control are provided in Supplementary Figure S1 (the first lane corresponds to an unrelated sample and was not analyzed). Data are representative of three independent experiments, with results presented as mean ± SD. ** P < 0.01, *** P < 0.001, **** P < 0.0001, compared with the control group.

Article Snippet: Membranes were blocked with 5% nonfat milk for 1 h at room temperature and incubated overnight at 4 °C with primary antibodies against GORAB (Proteintech, Wuhan, China; 17798–1-AP; 1:1000), AURKA (Cell Signaling Technology, Danvers, MA, USA; 14475T; 1:1000), AURKB (Cell Signaling Technology; 28711T; 1:1000), RhoC (Cell Signaling Technology; 3430T; 1:1000), RRM2 (Cell Signaling Technology; 65939T; 1:2000), PLK1 (Cell Signaling Technology; 4513T; 1:1000), α-N-catenin (Cell Signaling Technology; 2163T; 1:1000), and GAPDH (Abcam, Cambridge, UK; ab125247; 1:10,000) as the loading control.
