Microbiota differentiates colitis severity between WT and
Nlrp12−/− mice.
(a) NLRP12 gene expression between 10 pairs of
monozygotic healthy and UC twins (left panel). Composite of 8 NCBI GEO
ulcerative colitis (UC) studies (right panel) (Supplementary Fig. 1 shows the
other seven individual studies). (b) Body weight and
(c) percent survival of conventionally-raised mice treated with
3% DSS (WT, n=41;
Nlrp12−/−, n=42),
compiled from 4 independent experiments. (d) Body weight,
(e) percent survival, (f) disease-associated index
(DAI) and (g) colon length of germ-free (GF) WT (n=18) and
Nlrp12−/− (n=19)
mice given 1.5% DSS, compiled from 2 independent experiments.
(h) Blinded histopathology scoring of colons
(n=6/group). (i–k) Representative immunoblots and
densitometry of distal colon proteins from DSS-treated GF mice from 2
independent experiments (n=7/group). (l) Immunoblots and
densitometry of distal colon cytosolic (CYTO) and nuclear (NUC) protein
fractions from untreated specific-pathogen free (SPF) mice (n=9/group).
(m) Schematic comparing GF and conventionalized (exGF) mice.
(n–p) Immunoblots and densitometry of distal colon
proteins from untreated GF and exGF mice (n,p, n=4/group;
o, n=3/group). One dot or one lane represents one
mouse. Error bars show SEM. *p<0.05, **p<0.01,
***p<0.001 and
****p<0.0001, and n.s. means no significance
by two-tailed paired t test (a, left panel),
unpaired t test (a, right panel, b,
d, f–l, n–p) or
Log-rank (Mantel Cox) test (c and e).
