Abstract
Cystine-glutamate transporter (xCT) is a plasma membrane transporter that imports cystine and indirectly contributes to the oxidative stress resistance associated with increased intracellular glutathione levels. Canine adipose-derived stem cells (CADSCs) include an xCT-positive subpopulation and show relatively low expression of osteogenic markers during in vitro osteogenic differentiation. Sulfasalazine (SSZ), a drug used to treat rheumatoid arthritis, suppresses xCT expression in cancer cells. In this study, we found that the SSZ treatment at 100 µM significantly suppressed xCT mRNA expression in CADSCs but did not significantly affect cell proliferation under the same conditions. Additionally, this treatment decreased the intracellular glutathione concentration. During in vitro osteogenic differentiation, the SSZ treatment at 50 µM and 100 µM significantly increased alizarin red staining and its quantification, as well as the concentration-dependent osteogenic differentiation markers (BMP1 and SPP) mRNA expression. Our results suggested that SSZ enhances the osteogenic differentiation potential of CADSCs and can potentially exhibit a superior therapeutic profile in canine bone regenerative medicine.

Abstract
In the past decade, multifunctional peptides have attracted increasing attention in the biomedical field. Peptides possess many impressive advantages, such as high penetration ability, low cost, and etc. However, the short half-life and instability of peptides limit their application. In this study, a poly-peptide drug loading system (called HKMA composite) was designed based on the different functionalities of four peptides. The peptide compositions of HKMA composite from N-terminal to C-terminal were HCBP1, KLA, matrix metalloproteinase-2 (MMP-2)-cleavable peptide and albumin-binding domain. The targeting and lethality of HKMA to NSCLC cell line H460 sphere cells and the half-life of the system were measuredin vivo. The results showed that the HKMA composite had a long half-life and specific killing effect on H460 sphere cellsin vitroandin vivo. Our result proposed smart peptide drug loading system and provided a potential methodology for effective cancer treatment.
