Figure Lengend Snippet: Mitocelle can track and bind stressed mitochondria. (A) Schematic diagram of the human protein microarray analysis. (B) Mitocelle-interacting proteins were analyzed using the HuProt™ 3.1 human protein chip. The signal-to-noise ratio (SNR) for each spot was calculated as the ratio of the foreground-to-background signal. In addition, the GST signal intensity (red) was used for SNR normalization (left). A high-power image of NOX4 binding (white circles) is shown in the right panel. (C) Chord diagram visualizing the relationship between proteins with SNR > 1.0 and a list of mitochondrial, Golgi, and ER proteins. The SNR was calculated using the formula SNR = 20 log 10 (Is In −1 ), where ‘Is’ indicates the signal and ‘In’ indicates the noise. (D) Mouse chondrocytes treated with and without H 2 O 2 were analyzed by real-time live imaging of mitochondria (green) and Mitocelle (red) using a Celldiscoverer7 and an LSM900 confocal microscope. Intensity profiles of linear regions of interest are shown in the right panel. (E) To confirm mitochondrial dysfunction, we performed JC-1 staining and quantified JC-1 aggregates (red) and JC-1 monomers (green) as average intensities expressed in arbitrary units. Data are presented as means ± SD ( n = 5) and were assessed using one-way ANOVA with Bonferroni's test. ∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001.

Figure Lengend Snippet: Mitocelle interferes with the NOX4-p22phox interaction that contributes to ROS generation. (A) HuProt™ 3.1 Human Protein chip was used to analyze the effects of free Cy5 and Cy5-labeled Mitocelle (5 μg/mL) on Mitocelle-interacting proteins. The signal-to-noise ratio (SNR) of each point was calculated as the ratio of foreground to background signal. Additionally, a high-power image of p22phox binding (white circle) is shown in the right panel. (B) The SNR >1.0 proteins included 10 proteins known to be involved in ROS generation. (C) Schematic illustration of the principle of FRET and the acceptor photobleaching used for FRET measurements; CFP (donor), YFP (acceptor). (D) FRET detection by acceptor photobleaching. Chondrocytes were transfected for 24 h with vectors encoding YFP-NOX4 and CFP-p22phox, Mitocelles were applied, and transfection was continued for an additional 24 h. Fluorescence images were collected using YFP and CFP channels before and after photobleaching. To better show the changes in CFP fluorescence, pre- and post-bleaching CFP images are presented using pseudocolor. (E) FRET efficiency was measured after acceptor bleaching. Data are presented as means ± SD ( n = 10) and were assessed using (E) Mann-Whitney U test. ∗∗∗∗ P < 0.0001.

Article Title: Longitudinal serum autoantibody repertoire profiling identifies surgery-associated biomarkers in lung adenocarcinoma

doi: 10.1016/j.ebiom.2020.102674

Figure Lengend Snippet: The schematic diagram and work flow. Serum samples were collected longitudinally from the same patient at different time points before and after surgery. Representative samples were probed on the HuProt proteome microarray to identify candidates of surgery-associated antigens. A focused protein microarray with 14 identical subarrays was constructed by including the candidates of surgery-associated antigens. All the serum samples collected from the same patient were incubated on the focused microarray, some of the surgery-associated antigens were confirmed.
