Abstract
Cancer-associated fibroblasts (CAFs) assist in breast cancer (BRCA) invasion and immune resistance by overproduction of extracellular matrix (ECM). Herein, we develop FPC@S, a photodynamic immunomodulator that targets the ECM, to improve the photodynamic immunotherapy for fibrotic BRCA. FPC@S combines a tumor ECM-targeting peptide, a photosensitizer (protoporphyrin IX) and an antifibrotic drug (SIS3). After anchoring to the ECM, FPC@S causes ECM remodeling and BRCA cell death by generating reactive oxygen species (ROS) in situ. Interestingly, the ROS-mediated ECM remodeling can normalize the tumor blood vessel to improve hypoxia and in turn facilitate more ROS production. Besides, upon the acidic tumor microenvironment, FPC@S will release SIS3 for reprograming CAFs to reduce their activity but not kill them, thus inhibiting fibrosis while preventing BRCA metastasis. The natural physical barrier formed by the dense ECM is consequently eliminated in fibrotic BRCA, allowing the drugs and immune cells to penetrate deep into tumors and have better efficacy. Furthermore, FPC@S can stimulate the immune system and effectively suppress primary, distant and metastatic tumors by combining with immune checkpoint blockade therapy. This study provides different insights for the development of fibrotic tumor targeted delivery systems and exploration of synergistic immunotherapeutic mechanisms against aggressive BRCA.

Abstract
This study demonstrates the possibility of tumor decellularization in living animals. Subcutaneous Ehrlich tumor induced by isolated Ehrlich ascitic carcinoma cells in mice was used as a model. The study also presents methods for ex vivo decellularization of human gastric adenocarcinoma (HGA) and hepatocellular carcinoma (HCC) induced by diethylnitrosamine (DEN) in rat. Sodium dodecyl sulfate (SDS) and Triton X-100 were used as detergents for tumor decellularization. The detergents for HGA and HCC were administered through organ vessels. For intravital decellularization of Ehrlich's subcutaneous tumor, detergents were injected directly into the tumor parenchyma. The results of the study showed that the effectiveness of tumor decellularization using SDS and Triton X-100 depended on the size, structure, stiffness and density of the tumor, as well as on the concentration, route and speed of detergent administration. The study also showed that an hour after the initiation of decellularization, the central part of Ehrlich's tumor changed the color, and after three hours, it completely acquired a translucent white color. Chemical contamination of tissues surrounding the tumor with the detergents was not observed. Histological studies showed the complete absence of all cellular components of Ehrlich's tumor and a slightly deformed extracellular matrix (ECM). There were no loco-regional recurrences or metastases of Ehrlich's tumor within 150 days after decellularization. The developed intravital decellularization method allows the effective removal of the cellular components and the DNA content of Ehrlich's subcutaneous tumor without compromising animal health. Additionally, this method can destroy tumor ECM, which will significantly improve the delivery of anticancer drugs to the tumor cells. However, more detailed and extensive studies are needed to develop an in vivo technique for isolated decellularization of the tumor or a part of the organ with the tumor. It is also necessary to identify less toxic decellularization agents and to develop the most efficient route for their delivery to the tumor cells.

Abstract
Tumor extracellular matrix (ECM) not only forms a physical barrier for T cells infiltration, but also regulates multiple immunosuppressive pathways, which is an important reason for immunotherapy failure. The cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway plays a key role in activating CD8+ T cells, maintaining CD8+ T cells stemness and enhancing the antitumor effect. Herein, a zinc-organometallic framework vaccine (ZPM@OVA-CpG) prepared by self-assembly, which achieves site-directed release of Zn2+ in dendritic cell (DC) lysosomes and tumor microenvironment under acidic conditions, is reported. The vaccine actively targets DC, significantly enhances cGAS-STING signal, promotes DC maturation and antigen cross-presentation, and induces strong activation of CD8+ T cells. Meanwhile, the vaccine reaches the tumor site, releasing Zn2+ , significantly up-regulates the activity of matrix metalloproteinase-2, degrades various collagen components of tumor ECM, effectively alleviates immune suppression, and significantly enhances the tumor infiltration and killing of CD8+ T cells. ZPM@OVA-CpG vaccine not only solves the problem of low antigen delivery efficiency and weak CD8+ T cells activation ability, but also achieves the degradation of tumor ECM via the vaccine for the first time, providing a promising therapeutic platform for the development of efficient novel tumor vaccines.

Abstract
One of the main reasons why most cancer patients do not respond well to chemotherapy is that drugs cannot accumulate in tumors at an optimal dose, eventually resulting in failure to prevent cancer cell growth. To improve drug delivery efficiency, we engineered a highly efficient tumor-targeted and stroma-breaking nanocarrier by the modification of iron oxide nanoparticles (IONPs) with a tumor-targeting peptide c(RGDyK) and a hyaluronidase (HAase) on the surface. The yielding nanocomplex, c(RGDyK)-HAase-IONP, targeted the tumor by binding integrin αvβ3 and went deeply into the tumors by the degradation of hyaluronic acid (HA), which was highly expressed in the tumor extracellular matrix (ECM). Good biostability and a low pH preferred drug release profile were characterized for c(RGDyK)-HAase-IONP carrying DOX in vitro. c(RGDyK)-HAase-IONP showed an improved tumor-targeting (2.5 times higher) effect after intravenous injection in the MC38 tumor-bearing mice model, as determined by whole-body fluorescence imaging compared to the non-targeted IONPs without HAase. After 5 systemic treatments, c(RGDyK)-HAase-IONP/DOX (5 mg/kg of equivalent dose of DOX) significantly inhibited MC38 tumor growth (22.1 ± 7.4 times relative to the non-treated group). Elevated apoptosis and reduced proliferation in the tumor cell were detected in the c(RGDyK)-HAase-IONP/DOX treated tumors compared to the control groups. Overall, the highly efficient targeted nanocarrier c(RGDyK)-HAase-IONP demonstrated tremendous potency for improving drug delivery and tumor therapy efficacy by targeted degradation of the dense HA barrier in the tumor ECM. We determined that such a tumor stroma-degrading nanosystem was capable of reducing tumor recurrence and drug resistance and could ultimately improve clinical tumor treatment responses.

Abstract
Nanoparticles (NPs) are confronted with limited and disappointing delivery efficiency in tumors clinically. The tumor extracellular matrix (ECM), whose physical traits have recently been recognized as new hallmarks of cancer, forms a main steric obstacle for NP diffusion, yet the role of tumor ECM physical traits in NP diffusion remains largely unexplored. Here, we characterized the physical properties of clinical gastric tumor samples and observed limited distribution of NPs in decellularized tumor tissues. We also performed molecular dynamics simulations and in vitro hydrogel experiments through single-particle tracking to investigate the diffusion mechanism of NPs and understand the influence of tumor ECM physical properties on NP diffusion both individually and collectively. Furthermore, we developed an estimation matrix model with evaluation scores of NP diffusion efficiency through comprehensive analyses of the data. Thus, beyond finding that loose and soft ECM with aligned structure contribute to efficient diffusion, we now have a systemic model to predict NP diffusion efficiency based on ECM physical traits and provide critical guidance for personalized tumor diagnosis and treatment.

Abstract
The second near-infrared (NIR-II)-induced photothermal therapy (PTT) has attracted a great deal of attention in recent years due to its non-invasiveness and because it uses less energy. However, the penetration of photothermal agents into solid tumors is seriously impeded by the dense-tumor extracellular matrix (ECM) containing cross-linked hyaluronic acid (HA), thereby compromising the ultimate therapeutic effects. Herein, acid-labile metal-organic frameworks were employed as nanocarriers to efficiently mineralize hyaluronidase (HAase) and encapsulate Ag2S nanodots by a one-pot approach under mild conditions. The obtained nanocomposites (AHZ NPs) maintained enzyme activity and changed in size to prolong blood circulation and complete delivery of the cargo to the tumor. Moreover, the released HAase could specifically break out the HA to loosen ECM and enable the Ag2S nanodots to breeze through the tumor matrix space and gain access to the deep tumor. Under near-infrared laser irradiation, the AHZ NPs displayed remarkable fluorescence, outstanding photoacoustic signals, and excellent photothermal properties in the whole tumor. This work offers a promising two-pronged strategy via a decrease in nanoparticle size and the degradation of dense ECM for NIR-II multimodal imaging-guided PTT of deep tumors.

Abstract
The extracellular matrix (ECM) is involved in fundamental cellular processes and pathological progression of many diseases. While most research and current knowledge focuses on the processes of biological and mechanical changes in ECM signaling residing cancer cells to respond, little is known of the converse-of how cancer cells initiate the changes of ECM properties. Here, it is reported that blocking the cancer cell signaling leads to disruption of tumor ECM. Using recombinant proteins (RPs) and recombinant protein-drug conjugates (RPDCs) that simultaneously target both epidermal growth factor receptor and integrin, it is demonstrated that multireceptor-mediated active modulation of tumor ECM can inhibit and even reverse tumor remodeling of the physiological and structural microenvironment. These results not only provide insights into the regulatory roles of cancer cells in developing a protumoral microenvironment, but also introduce a new therapeutic platform or strategy to treat cancers.

Abstract
T cell infiltration into tumors is essential for successful immunotherapy against solid tumors. Herein, we found that the expression of hyaluronic acid synthases (HAS) was negatively correlated with patient survival in multiple types of solid tumors including gastric cancer. HA impeded in vitro anti-tumor activities of anti-mesothelin (MSLN) chimeric antigen receptor T cells (CAR-T cells) against gastric cancer cells by restricting CAR-T cell mobility in vitro. We then constructed a secreted form of the human hyaluronidase PH20 (termed sPH20-IgG2) by replacing the PH20 signal peptide with a tPA signal peptide and attached with IgG2 Fc fragments. We found that overexpression of sPH20-IgG2 promoted CAR-T cell transmigration through an HA-containing matrix but did not affect the cytotoxicity or cytokine secretion of the CAR-T cells. In BGC823 and MKN28 gastric cancer cell xenografts, sPH20-IgG2 promoted anti-mesothelin CAR-T cell infiltration into tumors. Furthermore, mice infused with sPH20-IgG2 overexpressing anti-MSLN CAR-T cells had smaller tumors than mice injected with anti-MSLN CAR-T cells. Thus, we demonstrated that sPH20-IgG2 can enhance the antitumor activity of CAR-T cells against solid tumors by promoting CAR-T cell infiltration.

Abstract
It is currently challenging to eradicate cancer. In the case of solid tumors, the dense and aberrant extracellular matrix (ECM) is a major contributor to the heterogeneous distribution of small molecule drugs and nano-formulations, which makes certain areas of the tumor difficult to treat. As such, much research is devoted to characterizing this matrix and devising strategies to modify its properties as a means to facilitate the improved penetration of drugs and their nano-formulations. This contribution presents the current state of knowledge on the composition of normal ECM and changes to ECM that occur during the pathological progression of cancer. It also includes discussion of strategies designed to modify the composition/properties of the ECM as a means to enhance the penetration and transport of drugs and nano-formulations within solid tumors. Moreover, a discussion of approaches to image the ECM, as well as ways to monitor changes in the ECM as a function of time are presented, as these are important for the implementation of ECM-modifying strategies within therapeutic interventions. Overall, considering the complexity of the ECM, its variability within different tissues, and the multiple pathways by which homeostasis is maintained (both in normal and malignant tissues), the available literature - while promising - suggests that improved monitoring of ECM remodeling in vivo is needed to harness the described strategies to their full potential, and match them with an appropriate chemotherapy regimen.

However, it is difficult for the released nanoparticles to penetrate deeply into tumors because of the dense collagen network in the tumor extracellular matrix, which greatly limits their antitumor effect. We hypothesized that the implantation of a hydrogel loaded with both nanoparticles and losartan (Los) might enhance penetration because Los has been proven to effectively reduce collagen levels in various tumors. Herein, we developed a nanoparticle/Los-loaded hydrogel system and evaluated the intratumoral distribution and anticancer effect after peritumoral implantation of nanoparticles. Methods Fluorescent polystyrene nanoparticles (FPNPs, size ~100 nm) and Los were simultaneously encapsulated in a polyethylene glycol (PEG) hydrogel to form the FPNP/Los-loaded hydrogel. After peritumoral implantation in 4T1 tumor-bearing mice for 2 weeks, intratumoral distributions of FPNPs and collagen level were determined. Based on the results, liposomal doxorubicin (Doxil, ~100 nm) was subsequently substituted for FPNPs in the hydrogel. The cellular uptake and cytotoxicity of the Doxil/Los-loaded hydrogel were studied, and the in vivo antitumor efficacy after peritumoral implantation was evaluated. Results Compared with a standard FPNP-loaded hydrogel, the FPNP/Los-loaded hydrogel resulted in enhanced penetration and reduced collagen levels after implantation. Thereafter, the potential of a Doxil/Los-loaded hydrogel for cancer treatment was studied. Doxorubicin was released from the hydrogel and induced effective cytotoxicity against 4T1 cells. The Doxil/Los-loaded hydrogel showed synergistic antitumor effects in 4T1 tumor-bearing mice and was more effective at tumor inhibition than the Doxil-loaded hydrogel. Conclusion This study provides a proof of principle that the implantation of nanoparticles/Los-loaded hydrogel can increase the intratumoral distribution and antitumor efficacy of nanoparticles, owing to collagen depletion by Los. Future studies may build on this strategy for enhanced tumor penetration of nanoparticles.

Abstract
Photodynamic therapy (PDT) holds great promise as a noninvasive and selective cancer therapeutic treatment in preclinical research and clinical practice; however, it has limited efficacy in the ablation of deep-seated tumor because of hypoxia-associated circumstance and poor penetration of photosensitizers to cancer cells away from the blood vessels. To tackle the obstacles, we propose a therapeutic strategy that synergizes upconversion nanophotosensitizers (UNPSs) with hyperbaric oxygen (HBO) to remodel the extracellular matrix for enhanced photodynamic cancer therapy. The UNPSs are designed to have an Nd3+-sensitized sandwiched structure, wherein the upconversion core serves as light transducers to transfer energy to the neighboring photosensitizers to produce reactive oxygen species (ROS). With HBO, photodynamic process can generate abundant ROS in the intrinsically hypoxic tumor. It is revealed for the first time that HBO-assisted PDT decomposes collagen in the extracellular matrix of tumor and thus facilitates the diffusion of oxygen and penetration of UNPSs into the deeper area of tumor. Such a synergic effect eventually results in a significantly enhanced therapeutic efficacy at a low laser power density as compared with that using UNPSs alone. In view of its good biosafety, the HBO-assisted and UNPSs-mediated PDT provides new possibilities for treatment of solid tumors.
