[PMID: 37956895 PMCID: PMC10824141 DOI: 10.1016/j.bcp.2023.115914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 11/06/2023] [Accepted: 11/07/2023] [Indexed: 11/21/2023]
Abstract
An important mechanism for cancer progression is degradation of the extracellular matrix (ECM) which is accompanied by the emergence and proliferation of an activated fibroblast, termed the cancer associated fibroblast (CAF). More specifically, an enzyme pathway identified to be amplified with local cancer progression and proliferation of the CAF, is fibroblast activation protein (FAP). The development and progression of heart failure (HF) irrespective of the etiology is associated with left ventricular (LV) remodeling and changes in ECM structure and function. As with cancer, HF progression is associated with a change in LV myocardial fibroblast growth and function, and expresses a protein signature not dissimilar to the CAF. The overall goal of this review is to put forward the postulate that scientific discoveries regarding FAP in cancer as well as the development of specific chemotherapeutics could be pivoted to target the emergence of FAP in the activated fibroblast subtype and thus hold translationally relevant diagnostic and therapeutic targets in HF.

Abstract
The prolyl-specific peptidase fibroblast activation protein-α (FAP-α) is expressed at very low or undetectable levels in nondiseased human tissues but is selectively induced in activated (myo)fibroblasts at sites of tissue remodeling in fibrogenic processes. In normal regenerative processes involving transient fibrosis FAP-α+(myo)fibroblasts disappear from injured tissues, replaced by cells with a normal FAP-α- phenotype. In chronic uncontrolled pathological fibrosis FAP-α+(myo)fibroblasts permanently replace normal tissues. The mechanisms of regulation and elimination of FAP-α expression in(myo)fibroblasts are unknown. According to a yeast two-hybrid screen and protein databanks search, we propose that the intracellular (co)-chaperone BAG6/BAT3 can interact with FAP-α, mediated by the BAG6/BAT3 Pro-rich domain, inducing proteosomal degradation of FAP-α protein under tissue homeostasis. In this Perspective, we discuss our findings in the context of current knowledge on the regulation of FAP-α expression and comment potential therapeutic strategies for uncontrolled fibrosis, including small molecule degraders (PROTACs)-modified FAP-α targeted inhibitors.

Abstract
Nanoarrays have been emerging as popular nanostructure platforms to investigate both cell behaviors and biological functions, due to the cell architecture respondence to the biointerface of nanostructures. Herein, we developed a series of aspect ratio tunable nanoarrays through a metal-assisted chemical etching method. Nanoarrays including nanoneedles, nanopillars, and nanoclusters were fabricated with a controllable aspect ratio. We found that nanostructures with a high aspect ratio (>10) induced significant alterations of cell physiological behaviors such as surface attachment, architecture deformation, viability, proliferation and motility. The cells on nanostructures with a high aspect ratio exhibited reorganized actin stress fibers and vimentin filaments, as well as reduced focal adhesion. This research enlarges the diversity of nanostructures on nano-bio interface investigation, provides a new insight for the surface-dependent architecture of cells, and offers unbiased understanding of factors influencing cell physiology.

Abstract
Multidrug resistance is one of the leading causes of chemotherapy failure in cancer patients. Early detection and capture of drug-resistant tumor cells can facilitate the monitoring of the therapy process and improve the prognosis of patients. In this study, novel P-glycoprotein (P-gp) antibody modified porous hydrogel particles are proposed for drug-resistant tumor cells capture. The hydrogel particles employ a highly biocompatible hydrogel, methacrylate gelatin (GelMA), as the carrier and replicate from the silica colloidal crystal beads. By the modification of P-gp antibody probes on their surfaces, the hydrogel particles are endowed with the ability to capture drug-resistant tumor cells, which overexpress specific components of P-gp on their membranes. Additionally, the acquired ordered porous nanostructure of the particles can provide not only more surface area for antibody immobilization but also a nanopatterned platform for highly efficient target cell capture. The above advantages make the porous hydrogel particles ideal for efficient capture and detection of the drug-resistant tumor cells, which can be expected to facilitate the point-of-care pharmacotherapy and promisingly improve the patient outcomes.

Abstract
Fibroblast activation protein (FAP) is a cell-surface serine protease that acts on various hormones and extracellular matrix components. FAP is highly upregulated in a wide variety of cancers, and is often used as a marker for pro-tumorigenic stroma. It has also been proposed as a molecular target of cancer therapies, and, especially in recent years, a great deal of research has gone into design and testing of diverse FAP-targeted treatments. Yet despite this growing field of research, our knowledge of FAP's basic biology and functional roles in various cancers has lagged behind its use as a tumor-stromal marker. In this review, we summarize and analyze recent advances in understanding the functions of FAP in cancer, most notably its prognostic value in various tumor types, cellular effects on various cell types, and potential as a therapeutic target. We highlight outstanding questions in the field, the answers to which could shape preclinical and clinical studies of FAP.

Abstract
Measurements of the intracellular state of mammalian cells often require probes or molecules to breach the tightly regulated cell membrane. Mammalian cells have been shown to grow well on vertical nanoscale structures in vitro, going out of their way to reach and tightly wrap the structures. A great deal of research has taken advantage of this interaction to bring probes close to the interface or deliver molecules with increased efficiency or ease. In turn, techniques have been developed to characterize this interface. Here, we endeavor to survey this research with an emphasis on the interface as driven by cellular mechanisms.

Abstract
Polyetheretherketone (PEEK) has an elastic modulus similar to that of the bone; however, its use as a material for bone repair is limited by bio-inert surface chemistry and poor osteogenesis-inducing capacity. To address this issue, the PEEK surface was activated by ultraviolet radiation-induced grafting of methacrylated hyaluronic acid (MeHA) and titanium dioxide (TiO2) nanofibers via a one-step process. The modified PEEK surface was characterized by X-ray photoelectron and Fourier-transform infrared spectroscopy, and the extent of surface modification was evaluated by measuring static contact angles. Atomic force microscopy revealed that the PEEK surface grafted with electrospun TiO2 had abundant nanofibers and a roughness that was comparable to that of human cortical bone. In vitro experiment, rat bone mesenchymal stem cells showed increased adhesion, proliferation, and osteogenic differentiation capacity on TiO2-modified as compared to unmodified PEEK. Thus, PEEK that is surface-modified with electrospun TiO2 and MeHA has enhanced biocompatibility and can be an effective material for use in orthopedic implants and medical devices.

Abstract
Over the past decade, vertical nanostructures have provided novel approaches for biomedical applications such as intracellular delivery/detection, specific cell capture, membrane potential measurement, and cellular activity regulation. Although the feasibility of the vertical nanostructures as a new biological tool has been thoroughly demonstrated, a better understanding of cell behavior on vertical nanostructures, in particular the effects of geometry, is essential for advanced applications. To investigate the cell behavior according to the variation of the spacing between vertical nanostructures, we have interfaced fibroblasts (NIH3T3) with density-controlled vertical silicon nanocolumn arrays (vSNAs). Over a wide range of vSNA densities, we observe three distinct cell settling regimes and investigate both overall cell behavior (adhesions, morphology, and mobility) and detailed biomacromolecule variance (F-actin and focal adhesion) across these regimes. We expect that these systematic observations could serve as a guide for improved nanostructure array design for the desired cell manipulation.

Abstract
High aspect ratio nanomaterials, such as vertically aligned silicon nanowire (SiNW) substrates, are three-dimensional topological features for cell manipulations. A high density of SiNWs significantly affects not only cell adhesion and proliferation but also the delivery of biomolecules to cells. Here, we used polydopamine (PD) that simply formed a thin coating on various material surfaces by the action of dopamine as a bioinspired approach. The PD coating not only enhanced cell adhesion, spreading, and growth but also anchored more siRNA by adsorption and provided more surface concentration for substrate-mediated delivery. By comparing plain and SiNW surfaces with the same amount of loaded siRNA, we quantitatively found that PD coating efficiently anchored siRNA on the surface, which knocked down the expression of a specific gene by RNA interference. It was also found that the interaction of SiNWs with the cell membrane perturbed the lateral diffusion of lipids in the membrane by fluorescence recovery after photobleaching. The perturbation was considered to induce the effective delivery of siRNA into cells and allow the cells to carry out their biological functions. These results suggest promising applications of PD-coated, high-density SiNWs as simple, fast, and versatile platforms for transmembrane delivery of biomolecules.

Abstract
Titanium and its alloys remain the most popular choice as a medical implant material because of its desirable properties. The successful osseointegration of titanium implants is, however, adversely affected by the presence of bacterial biofilms that can form on the surface, and hence methods for preventing the formation of surface biofilms have been the subject of intensive research over the past few years. In this study, we report the response of bacteria and primary human fibroblasts to the antibacterial nanoarrays fabricated on titanium surfaces using a simple hydrothermal etching process. These fabricated titanium surfaces were shown to possess selective bactericidal activity, eliminating almost 50% of Pseudomonas aeruginosa cells and about 20% of the Staphylococcus aureus cells coming into contact with the surface. These nano-patterned surfaces were also shown to enhance the aligned attachment behavior and proliferation of primary human fibroblasts over 10 days of growth. These antibacterial surfaces, which are capable of exhibiting differential responses to bacterial and eukaryotic cells, represent surfaces that have excellent prospects for biomedical applications.

Abstract
Inorganic nanowires are among the most attractive functional materials, which have emerged in the past two decades. They have demonstrated applications in information technology and energy conversion, but their utility in biological or biomedical research remains relatively under-explored. Although nanowire-based sensors have been frequently reported for biomolecular detection, interfacing nanowire arrays and living mammalian cells for the direct analysis of cellular functions is a very recent endeavor. Cell-penetrating nanowires enabled effective delivery of biomolecules, electrical and optical stimulation and recording of intracellular signals over a long period of time. Non-penetrating, high-density nanowire arrays display rich interactions between the nanostructured substrate and the micro/nanoscale features of cell surfaces. Such interactions enable efficient capture of rare cells including circulating tumor cells and trafficking leukocytes from complex biospecimens. It also serves as a platform for probing cell traction force and neuronal guidance. The most recent advances in the field that exploits nanowire arrays (both penetrating and non-penetrating) to perform rapid analysis of cellular functions potentially for disease diagnosis and monitoring are reviewed.
