Background Insulin-like growth factor binding protein-related protein 1 （IGFBPrP1） can activate hepatic stellate cells and increase extracellular matrix （ECM） in vitro. However, the effects of IGFBPrP1 in mice with hepatic fibrosis, and the mechanisms of these effects, are currently unknown. We aim to address these issues in this study. Methods Intraperitoneal injection of thioacetamide （TAA） is a classic method for establishing a mouse model of hepatic fibrosis. Using this model, we administered anti-IGFBPrP1 antibody, again via intraperitoneal injection. The morphological changes of liver fibrosis were observed with both HE and Masson stainning. The immunohistochemical assays and Western blotting were used to measure changes in IGFBPrP1, a-smooth muscle actin （a-SMA） and ECM in liver tissues, and the expression of transforming growth factor-β1 （TGF-β1） and Smad3. Data were statistically analyzed using one-way analysis of variance （ANOVA）, the SNK-q test for inter-group differences. Results The Masson staining analysis showed that compared with normal control group, content of collagen fiber in TAA5w group was significantly increased （P 〈0.01）, and it was significantly decreased in TAA5w/alGFBPrP1 group compared with in TAA5w group （P 〈0.01）. The expression of hepatic IGFBPrP1, a-SMA, TGF-β1, Smad3, collagen 1 and fibronectin （FN） was significantly up-regulated in the TAA5w group （P 〈0.01）. Anti-IGFBPrP1 treatment reversed these changes （P 〈0.01）. Conclusions IGFBPrP1 plays an important role in the development of hepatic fibrosis. Anti-IGFBPrP1 prevents fibrosis in mice by suppressing the activation of hepatic stellate cells, inhibiting the synthesis of major components of the ECM （namely, collagen I and FN）. The mechanism for this suppression of fibrosis is associated with the TGF-β1/Smad3 signaling pathways.

Despite the rapid development of probes for targeting single organelle, the construction of robust dual-organelle targeting probes with multicolor emission was rarely reported. Herein, two dual-emissive aggregation-induced emission luminogens(AIEgens)with donor-π-acceptor structures were designed and synthesized, namely QT-1 and QF-2. Both two AIEgens exhibited excitation wavelength-dependence defying the Kasha's rule, and could stain lipid droplets(LDs) and mitochondria in blue and red fluorescence, respectively. Moreover, thanks to the near-infrared emission and abundant reactive oxygen species(ROS) generation efficiency of QT-1, it was chosen as a photodynamic therapy agent to selectively kill cancer cells from normal cells. Upon light irradiation, an obvious decrease of mitochondrial membrane potential(MMP) and serious change of mitochondrial shape in cells were observed, which corresponded to the efficient inhibition of tumor growth in vivo. This work afforded a promising strategy for the construction of multicolor emission by tuning anti-Kasha behaviors and expanding their application in dualorganelle targeting-based phototheranostics.
