Article Title: Postbiotic Parabacteroides Distasonis Supplementation Enhances Intestinal and Skeletal Muscle Function in Aged Mice

doi: 10.14336/AD.2025.0188

Figure Lengend Snippet: Postbiotic Pd modifies mitochondria in a colon cell line. (A) Right panel-representative images of HCT116 treated or not with postbiotic Pd for 24h and labeled with TMRE to determine mitochondrial morphology. Bar = 10 µm. Left panel- bar graphs of the mitochondrial length analysis. Data are expressed as MEAN ± SEM of five independent experiments ****p≤0.0001. Mann-Whitney test . (B) Upper panel- representative Western blot of PGC1α and GADPH as a loading control in HCT116 cells treated or not with postbiotic Pd. Bottom panel- Bar graphs represent quantification of PGC1α/GADPH expressed as MEAN ± SEM of five independent experiments. ∗p < 0.05. Mann-Whitney test . (C) Upper panel- representative Seahorse trace of HCT116 cells treated or not with postbiotic Pd. A; oligomycin (1 µM), B;FCCP (250 µM), C; rotenone plus antimycin A (1 µM each). Bottom panel- basal and maximum OCR of HCT116 cells treated or not with postbiotic Pd. MEAN ± SEM of three independent experiments with 10 replicates each. ***P < 0.001 compared to control. Mann-Whitney test. (D) Upper panel- representative Western blot of CHOP and β-actin as a loading control in HCT116 cells treated or not with postbiotic Pd. Bottom panel- bar graphs represent quantification of CHOP/β-actin expressed as MEAN ± SEM of 3 independent experiments. ∗p < 0.05. Mann-Whitney test . (E) Upper panel- representative Western blot of VDAC1 and β-actin as a loading control in colon mucosa samples from 26-months-old mice treated or not with postbiotic Pd. Bottom panel- bar graphs represent quantification of VDAC1/β-actin expressed as MEAN ± SEM. Note that β-actin blot in is the same as in this figure, as the same membrane was stripped and re-probed for VDAC1. N = 3 in the control group and 4 for the Pd treated group. ∗p < 0.05. Mann-Whitney test .

Article Title: MBD2 suppresses SFRP1 expression and promotes colorectal cancer development by blocking MED19 binding to its methylated promoter

doi: 10.1080/15384047.2026.2667568

Figure Lengend Snippet: Inhibition of MBD2 upregulated the expression of SFRP1 and inhibited Wnt signaling pathway activation. (A and B) The interference efficiency of MBD2 siRNAs at the protein level in SW480 and HCT116 cells. (C) Silencing MBD2 increased the mRNA level of SFRP1. (D and E) Silencing MBD2 increased the protein level of SFRP1 and decreased the protein level of β -catenin. (F) KCC07 disrupted MBD2 binding to the SFRP1 promoter. (G and H) The half inhibitory concentration (IC50) of KCC07 in CRC cells. (I) KCC07 increased the mRNA level of SFRP1. (J and K) KCC07 increased the protein level of SFRP1 and decreased the protein level of β -catenin. n = 6, *indicates p < 0.05, **indicates p < 0.01.

Article Snippet: Normal colon mucosa cell line NCM460 (ATCC, CRL-1642 TM ) and the human colorectal cancer cell lines HCT116 (ATCC, CCL-247 TM ) and SW480 (ATCC, CCL-228 TM ) were purchased from iCell, and all had STR identification reports.

Article Title: MBD2 suppresses SFRP1 expression and promotes colorectal cancer development by blocking MED19 binding to its methylated promoter

doi: 10.1080/15384047.2026.2667568

Figure Lengend Snippet: The effect of KCC07 on recovering SFRP1 expression requires MED19. (A and B) The interfering efficiency of MED19 siRNAs at the protein level in SW480 and HCT116 cells. (C–F) Treatment with KCC07 resulted in increased SFRP1 expression and increased β -catenin expression at both the mRNA and protein levels in CRC cells, while simultaneous knockdown of MED19 abolished these effects. n = 6, ns indicates not significant, *indicates p < 0.05, and **indicates p < 0.01.
