CARD3 is Involved in F. nucleatum-Mediated Autophagy in vivo.(A-D) Bioluminescence imaging (BLI) was used to monitor metastases (A) in the lungs (B), livers (C), and intestines (D) of wild-type BALB/cJ mice (n = 5-6 mice/group). Representative gross lungs and H&E-stained lung and liver sections from mice (A). The data are presented as the means ± SDs (*P < 0.05, **P < 0.01, and ***P < 0.001; Mann-Whitney test). (E-F) The metastatic foci in lungs (E) and livers (F) were counted. The data are presented as the means ± SDs. (*P < 0.05, **P < 0.01, and ***P < 0.001; Mann-Whitney test).
