Correction: Ma et al. Effects of Probiotic-Fermented Deer Bone Water Extract on Immune Regulation and Gut Microbiota in Rheumatoid Arthritis via the NOTCH Signaling Pathway. Foods 2025, 14, 3802

In the original publication [1], there were two mistakes in Figures 7 and 8 as published. During the manuscript preparation process, a copy–paste error occurred in the image layout, resulting in a duplication issue. Specifically, the 0 h photograph of the CK group in Figure 7G overlaps with that of the LPS+MTX group at the same time point. Additionally, the 2D cross-sectional image of the DAPT group in Figure 8C (Micro-CT image) is identical to that of the BbFH group in Figure 3J (Micro-CT image). The corrected Figure 7 and Figure 8 appear below.

Figure 7.

Influence of BbF on the Anti-inflammatory Activity, Invasion and Migration of RA-RAW264.7 Cells. (A) Effect of BbF on the viability of RAW264.7 cells (** p < 0.01). (B–D) Inflammatory cytokines measured in cell culture supernatant include TNF-α, IL-1β, and IL-6. (E–H) RA-RAW264.7 cell migration and invasion. (I) Immunofluorescence detection of NOTCH 3 in RA-RAW264.7 cells. (**** p < 0.0001, *** p < 0.001, ** p < 0.01, * p < 0.1, ns (not significant) vs. CK; #### p < 0.0001, ### p < 0.001, # p < 0.1, ns (not significant) vs. LPS).

Figure 8.

DAPT inhibits the activation of the NOTCH signaling pathway. (A) DAPT reduces the severity of swelling and inflammatory factor assays in RA. (B) Hematoxylin and Eosin Staining. (C) DAPT alleviates bone erosion in RA. (D) Expressions of related marker proteins and Gray scale analysis of Western blot. (**** p < 0.0001, *** p < 0.001, ** p < 0.01, * p < 0.1, ns (not significant) vs. CK).

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
