Article Title: CNKSR2 interactome analysis indicates its association with the centrosome/microtubule system
doi: 10.4103/NRR.NRR-D-23-01725
Figure Lengend Snippet: CNKSR2 knockdown disturbs centrosome-related functions. (A) Western blot analysis of CNKSR2 expression in N2A cells infected with CNKSR2 KD and NC lentivirus ( n = 3). (B) Typical IF images of N2A cells showed that cells in the CNKSR2 KD group were smaller and rounder than those in the NC group. DAPI was used to stain nuclei (blue). EGFP proteins (green) were expressed by the lentivirus-infected cells. Immunostaining of α-tubulin (red, Alexa Fluor 546) in N2A cells. Scale bars: 10 µm. (C, D) Statistical analysis of the average cell spreading area (C) and cell aspect ratio (D) of N2A cells infected with the lentiviruses ( n = 11 images from three biological replicates; the total number of cells quantified was 268 in the CNKSR2 KD group and 151 in the NC group). (E) CCK8 analysis of N2A cells infected with the lentiviruses ( n = 3). (F) RT-PCR analysis of MKI67 gene expression in N2A cells infected with the lentiviruses ( n = 6). (G) Typical images of the Transwell assays showed that N2A cells in the CNKSR2 KD group had higher motility than those in the NC group ( n = 10). Scale bars: 100 µm. Data are presented as mean ± SD. * P < 0.05, ** P < 0.01, *** P < 0.001 (unpaired two-tailed Student’s t -test). CCK8: cell counting kit-8; CNKSR2: connector enhancer of kinase suppressor of Ras 2; DAPI: 4′,6-diamidino-2-phenylindole; EGFP: enhanced green fluorescent protein; GAPDH: glyceraldehyde-3-phosphate dehydrogenase IF: immunofluorescence; KD: knock down; MKI67: proliferation marker protein Ki-67; N2A: Neuro 2A; NC: negative control; ns: no significance; RT-PCR: real-time polymerase chain reaction.
Article Snippet: The CNKSR2 antibody (host: rabbit, concentration: 1 mg/mL) used for IP experiments was purchased from Abcepta Biotech (Suzhou, Jiangsu Province, China, Cat# AP69182, RRID: AB_3083424), and rabbit total IgG, used as the negative control antibody, was purchased from Sangon Biotech (Shanghai, China, Cat# D110502, RRID: AB_3083429).
