Abstract
Herein, we present a straightforward synthetic route for the design and synthesis of diverse heterobifunctional cyanine 5 dyes. We optimized the workup by harnessing the pH- and functional group-dependent solubility of the asymmetric cyanine 5 dyes. Therefore, purification through chromatography is deferred until the last synthesis step. Demonstrating successful large-scale synthesis, our modular approach prevents functional group degradation by introducing them in the last synthesis step. These modifiable heterobifunctional dyes offer significant utility in advancing biological studies.

[PMID: 36547328 PMCID: PMC9777555 DOI: 10.3390/gels8120804] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/01/2022] [Accepted: 12/02/2022] [Indexed: 12/13/2022] Open
Abstract
Hydroxyapatite (HAp) as natural bone composition is highly osteoinductive. To harvest its osteoinductivity in bone regenerative engineering, the HAp-supporting hydrogel is urgently needed to minimize inhomogeneous aggregation of HAp. Here, we developed a HAp-stabilizing hydrogel based on peptide self-assembly. FmocFFRR was efficient for HAp-capping due to arginine-phosphate interaction. Tethering FmocFFRR on the HAp surface facilitated self-assembly to form FmocFFRR/HAp hybrid hydrogel, enabling stable dispersion of HAp in it. The molecular interactions between FmocFFRR and HAp particles were studied using microscopic and spectral characterizations. FmocFFRR/HAp hydrogel exhibited more enhanced mechanical properties than FmocFFRR. The biocompatibility of FmocFFRR/HAp hydrogel was verified using an ATP assay and live-dead staining assay. More importantly, FmocFFRR/HAp hydrogel not only enabled cell attachment on its surface, but also supported 3D cell culturing inside the hydrogel. Further, 3D culturing of MC3T3-E1 preosteoblasts inside FmocFFRR/HAp hydrogel significantly enhanced the expressions of osteogenesis markers, including alkaline phosphate (ALP), type-I collagen (COL1), and osteocalcin (OCN), demonstrating the promoting effect of osteoblast differentiation. These findings inspire its potential application in bone regenerative engineering.

Abstract
This feature article introduces the design of self-assembling peptides that serve as the basic building blocks for the construction of extracellular matrix (ECM)-like structure in the vicinity of the plasma membrane. By covalently conjugating a bioactive motif, such as membrane protein binding ligand or enzymatic responsive building block, with a self-assembling motif, especially the aromatic peptide, a self-assembling peptide that retains bioactivity is obtained. Instructed by the target membrane protein or enzyme, the bioactive peptides self-assemble into ECM-like structure exerting various stimuli to regulate the cellular response via intracellular signaling, especially mechanotransduction. By briefly summarizing the properties and applications (e.g., wound healing, controlling cell motility and cell fate) of these peptides, we intend to illustrate the basic requirements and promises of the peptide assembly as a true bottom-up approach in the construction of artificial ECM.

Abstract
Cell-based therapy for disease treatment involves the transplantation of cells obtained either from self or others into relevant patients. While cells constituting the body tissues maintain homeostasis by performing remarkable functions through complicated cell-cell interactions, transplanted cells, which are generally cultured as a monolayer, are unable to recapitulate similar interactions in vivo. The regulation of cell-cell interactions can immensely increase the function and therapeutic effect of transplanted cells. This review aims to summarize the methods of regulating cell-cell interactions that could significantly increase the therapeutic effects of transplanted cells. The first method involves the generation of multicellular spheroids by three-dimensional cell culture. Spheroid formation greatly improved the survival and therapeutic effects of insulin-secreting cells in diabetic mice after transplantation. Moreover, mixed multicellular spheroids, composed of insulin-secreting cells and aorta endothelial cells or fibroblasts, were found to significantly improve insulin secretion. Secondly, adhesamine derivatives, which are low-molecular-weight compounds that accelerate cell adhesion and avoid anoikis and anchorage-dependent apoptosis, have been used to improve the survival of bone marrow-derived cells and significantly enhanced the therapeutic effects in a diabetic mouse model of delayed wound healing. Finally, the avidin-biotin complex method, a cell surface modification method, has been applied to endow tumor-homing mesenchymal stem cells with anti-tumor ability by modifying them with doxorubicin-encapsulated liposomes. The modified cells showed excellent effectiveness in cell-based cancer-targeting therapy. The discussed methods can be useful tools for advanced cell-based therapy, promising future clinical applications.

Abstract
Heparan sulfate (HS) has important emerging roles in oncogenesis, which represents potential therapeutic strategies for human cancers. However, due to the complexity of the HS signaling network, HS-targeted synthetic cancer therapeutics has never been successfully devised. To conquer the challenge, we developed HS-instructed self-assembling peptides by decorating the "Cardin-Weintraub" sequence with aromatic amino acids. The HS-binding interactions induce localized accumulation of synthetic peptides triggering molecular self-assembly in the vicinity of highly expressed Heparan sulfate proteoglycans (HSPGs) on the cancer cell membrane. The nanostructures hinder the binding of HSPG with metastasis promoting protein-heparin-binding EGF-like growth factor (HBEGF) inhibiting the activation of focal adhesion kinase (FAK) and extracellular signal-regulated kinase (ERK). Our study proved that HS-instructed self-assembly is a promising synthetic therapeutic strategy for targeted cancer migration inhibition.

Abstract
Immune potentiators, termed adjuvants, trigger early innate immune responses to ensure the generation of robust and long-lasting adaptive immune responses of vaccines. Presented here is a study that takes advantage of a self-assembling small-molecule library for the development of a novel vaccine adjuvant. Cell-based screening of the library and subsequent structural optimization led to the discovery of a simple, chemically tractable deoxycholate derivative (molecule 6, also named cholicamide) whose well-defined nanoassembly potently elicits innate immune responses in macrophages and dendritic cells. Functional and mechanistic analyses indicate that the virus-like assembly enters the cells and stimulates the innate immune response through Toll-like receptor 7 (TLR7), an endosomal TLR that detects single-stranded viral RNA. As an influenza vaccine adjuvant in mice, molecule 6 was as potent as Alum, a clinically used adjuvant. The studies described here pave the way for a new approach to discovering and designing self-assembling small-molecule adjuvants against pathogens, including emerging viruses.

Abstract
Mesenchymal stem cells (MSCs) have a tumor-homing ability-they accumulate inside tumors after systemic injection, and may thus be useful as carriers for tumor-targeting therapy. To use MSCs effectively as an anti-cancer therapy, they must first be functionalized with a large amount of anti-cancer drugs without causing any significant changes to their tumor-tropism. In the present study, we attempted to modify the cell surface of MSCs with doxorubicin-loaded liposomes (DOX-Lips), using the avidin-biotin complex method, and evaluated delivery efficiency and anti-tumor efficacy of DOX-Lip-modified MSCs. The amount of DOX in DOX-Lip-modified C3H10T1/2 cells, a murine mesenchymal stem cell line, was approximately 21.5 pg per cell, with no significant changes to the tumor-tropism of C3H10T1/2 cells. Notably, DOX-Lip-modified C3H10T1/2 cells significantly suppressed the proliferation of firefly luciferase-expressing murine colon adenocarcinoma colon26/fluc cells, compared to DOX-Lips alone. Fluorescent DOX accumulated at the cell contact surface and inside green fluorescence protein-expressing colon26 (colon26/GFP) in co-cultures of DOX-Lip-modified C3H10T1/2 and colon26/GFP cells. This localized distribution was not observed when only DOX-Lips was added to colon26/GFP cells. These results suggest that DOX-Lips are efficiently delivered from DOX-Lip-modified C3H10T1/2 cells to the neighboring colon26 cells. Furthermore, DOX-Lip-modified C3H10T1/2 cells suppressed tumor growth in subcutaneous tumor-bearing mice, and in a lung metastasis mouse model. Taken together, these results indicate that the intercellular delivery of DOX may be enhanced using DOX-Lip-modified MSCs as an efficient carrier system for targeted tumor therapy.

Abstract
Metastasis is one of the ongoing challenges in cancer therapy which most treatments failed to address. Inspired by the upregulated expression of both integrin β1 and heparan sulfate in metastatic tumors, we developed an integrin/HS dual-targeting peptide assembly that selectively inhibits cancer cell migration and invasion. Particularly, the dual-targeting peptide self-assembles into nanofibrous microdomains specifically on the cancer cell membrane, triggering spatial organization of integrins, which form clusters on the apical membrane. Via the actin cytoskeleton that physically connects to integrin clusters, the oncogene yes-associated protein, which regulates cancer metastasis, is deactivated. We showed that in multiple cancer cell lines, including the highly metastatic pancreatic cancer cells, the dual-targeting peptide exerts potent and dose-dependent antimetastatic effects. Our work illustrates how basic biochemical insights can be exploited as the basis for nano-biointerface fabrication, which is potentially a general design strategy for nanomedicine development.
