doi: 10.1016/j.bbrep.2025.102386

Figure Lengend Snippet: RMST-KO reduces fibrosis in mouse skin wound healing. (A) Differences of RMST expression between unwounded skin and the 21 dps group. (B) Agarose gel electrophoresis confirmed the successful knockout of RMST. (C) QPCR assay showing the expression of RMST 21 dps. (D) H&E and Masson staining of the wounds 21 dps as indicated. (E–F) RMST-KO reduced the (E) thickness and (F) area of neogenic fibrous tissue at 21 dps. (G–H) QPCR showing the COL1A1 and α-SMA levels were significantly decreased in the RMST-KO group compared to the WT group 21 dps. (I) Representative blot of COL1A1 and α-SMA 21 dps. (J–K) Statistical analysis of the immunoblot bands indicated that RMST-KO significantly suppressed the expression of COL1A1 and α-SMA 21 dps. Data were shown as mean ± SD, n = 6, ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001.

Figure Lengend Snippet: Blood and vascular proteins co-exist with intracellular Aβ in neural cells in AD frontal lobe tissues and may also be related to lysosome instability. (A) Representative images showing the co-expression of blood-related markers HBA (green, Alexa Fluor 488) and Aβ (red, Alexa Fluor 594). (B) Representative images showing the co-expression of vascular markers ACTA2 (green, Alexa Fluor 488) and Aβ (red, Alexa Fluor 594). (C) Representative images showing the co-expression of vascular markers ColIV (red, Alexa Fluor 594) and Aβ (green, Alexa Fluor 488). The colocalization of markers is indicated by yellow arrows. Two small blood vessels are indicated by asterisks in the ColIV staining panel. (D) Intracellular HBA (green, Alexa Fluor 488) expression domains overlapped with the region of lysosomal destabilization, which is indicated by enlarged and clustered lysosomal compartments and diffuse Cathepsin D staining (red, Alexa Fluor 594, marked with yellow dashed circles). Control HBA-unaffected lysosomes are indicated by white arrows. Scale bars: 25 μm. ACTA2: Smooth muscle actin alpha 2; AD: Alzheimer’s disease; Aβ: amyloid-β; ColIV: collagen type IV; HBA: hemoglobin.
