[PMID: 39174548 PMCID: PMC11341566 DOI: 10.1038/s41467-024-51734-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 08/16/2024] [Indexed: 08/24/2024] Open
Abstract
A variety of therapeutic possibilities have emerged for skillfully regulating protein function or conformation through intermolecular interaction modulation to rectify abnormal biochemical reactions in diseases. Herein, a devised strategy of enzyme coordinators has been employed to alleviate postoperative pancreatic fistula (POPF), which is characterized by the leakage of digestive enzymes including trypsin, chymotrypsin, and lipase. The development of a dextrorotary (D)-peptide supramolecular gel (CP-CNDS) under this notion showcases its propensity for forming gels driven by intermolecular interaction. Upon POPF, CP-CNDS not only captures enzymes from solution into hydrogel, but also effectively entraps them within the internal gel, preventing their exchange with counterparts in the external milieu. As a result, CP-CNDS completely suppresses the activity of digestive enzymes, effectively alleviating POPF. Remarkably, rats with POPF treated with CP-CNDS not only survived but also made a recovery within a mere 3-day period, while mock-treated POPF rats had a survival rate of less than 5 days when experiencing postoperative pancreatic fistula, leak or abscess. Collectively, the reported CP-CNDS provides promising avenues for preventing and treating POPF, while exemplifying precision medicine-guided regulation of protein activity that effectively targets specific pathogenic molecules across multiple diseases.

Abstract
Compensation and intracellular storage of PD-L1 may compromise the efficacy of antibody drugs targeting the conformational blockade of PD1/PD-L1 on the cell surface. Alternative therapies aiming to reduce the overall cellular abundance of PD-L1 thus might overcome resistance to conventional immune checkpoint blockade. Here we show by bioinformatics analysis that colon adenocarcinoma (COAD) with high microsatellite instability (MSI-H) presents the most promising potential for this therapeutic intervention, and that overall PD-L1 abundance could be controlled via HSC70-mediated lysosomal degradation. Proteomic and metabolomic analyses of mice COAD with MSI-H in situ unveil a prominent acidic tumor microenvironment. To harness these properties, an artificial protein, IgP β, is engineered using pH-responsive peptidic foldamers. This features customized peptide patterns and designed molecular function to facilitate interaction between neoplastic PD-L1 and HSC70. IgP β effectively reduces neoplastic PD-L1 levels via HSC70-mediated lysosomal degradation, thereby persistently revitalizing the action of tumor-infiltrating CD8 + T cells. Notably, the anti-tumor effect of lysosomal-degradation-based therapy surpasses that of antibody-based immune checkpoint blockade for MSI-H COAD in multiple mouse models. The presented strategy expands the use of peptidic foldamers in discovering artificial protein drugs for targeted cancer immunotherapy.

Abstract
Cancer remains a significant risk to human health. Nanomedicine is a new multidisciplinary field that is garnering a lot of interest and investigation. Nanomedicine shows great potential for cancer diagnosis and treatment. Specifically engineered nanoparticles can be employed as contrast agents in cancer diagnostics to enable high sensitivity and high-resolution tumor detection by imaging examinations. Novel approaches for tumor labeling and detection are also made possible by the use of nanoprobes and nanobiosensors. The achievement of targeted medication delivery in cancer therapy can be accomplished through the rational design and manufacture of nanodrug carriers. Nanoparticles have the capability to effectively transport medications or gene fragments to tumor tissues via passive or active targeting processes, thus enhancing treatment outcomes while minimizing harm to healthy tissues. Simultaneously, nanoparticles can be employed in the context of radiation sensitization and photothermal therapy to enhance the therapeutic efficacy of malignant tumors. This review presents a literature overview and summary of how nanotechnology is used in the diagnosis and treatment of malignant tumors. According to oncological diseases originating from different systems of the body and combining the pathophysiological features of cancers at different sites, we review the most recent developments in nanotechnology applications. Finally, we briefly discuss the prospects and challenges of nanotechnology in cancer.

Abstract
The mechanism research of skin wrinkles, conducted on volunteers underwent high-intensity desk work and mice subjected to partial sleep deprivation, revealed a significant reduction in dermal thickness associated with the presence of wrinkles. This can be attributed to the activation of facial nerves in a state of hysteria due to an abnormally elevated interaction between SNAP25 and RAB3A proteins involved in the synaptic vesicle cycle (SVC). Facilitated by AI-assisted structural design, a refined peptide called RSIpep is developed to modulate this interaction and normalize SVC. Drawing inspiration from prions, which possess the ability to protect themselves against proteolysis and invade neighboring nerve cells through macropinocytosis, RSIpep is engineered to demonstrate a GSH-responsive reversible self-assembly into a prion-like supermolecule (RSIprion). RSIprion showcases protease resistance, micropinocytosis-dependent cellular internalization, and low adhesion with constituent molecules in the cuticle, thereby endowing it with the transdermic absorption and subsequent biofunction in redressing the frenzied SVC. As a facial mud mask, it effectively reduces periorbital and perinasal wrinkles in the human face. Collectively, RSIprion not only presents a clinical potential as an anti-wrinkle prion-like supermolecule, but also exemplifies a reproducible instance of bionic strategy-guided drug development that bestows transdermal ability upon the pharmaceutical molecule.

Abstract
The combination of phototherapy and chemotherapy holds great potential for cancer treatment, while hypoxia in tumor as well as unexpected drug release largely restricts anticancer therapy. Inspired by the natural intelligence, herein, for the first time, a "bottom-up" protein self-assembly strategy mediated by near-infrared (NIR) quantum dots (QDs) with multicharged electrostatic interactions is presented to develop a tumor microenvironment (TME)-responsive theranostic nanoplatform for imaging-guided synergistic photodynamic therapy (PDT)/photothermal therapy (PTT)/chemotherapy. Catalase (CAT) possesses diverse surface charge distribution under different pH conditions. After modification by chlorin e6 (Ce6), the formulated CAT-Ce6 with patchy negative charges can be assembled with NIR Ag2 S QDs by regulating their electrostatic interactions, allowing for effective incorporation of specific anticancer drug oxaliplatin (Oxa). Such Ag2 S@CAT-Ce6@Oxa nanosystems are able to visualize nanoparticle (NP) accumulation to guide subsequent phototherapy, together with significant alleviation of tumor hypoxia to further enhance PDT. Moreover, the acidic TME triggers controllable disassembly through weakening the CAT surface charge to disrupt electrostatic interactions, allowing for sustained drug release. Both in vitro and in vivo results demonstrate remarkable inhibition of colorectal tumor growth with a synergistic effect. Overall, this multicharged electrostatic protein self-assembly strategy provides a versatile platform for realizing TME-specific theranostics with high efficiency and safety, promising for clinical translation.

Abstract
Intensive cancer treatment with drug combination is widely exploited in the clinic but suffers from inconsistent pharmacokinetics among different therapeutic agents. To overcome it, the emerging nanomedicine offers an unparalleled opportunity for encapsulating multiple drugs in a nano-carrier. Herein, a two-step super-assembled strategy was performed to unify the pharmacokinetics of a peptide and a small molecular compound. In this proof-of-concept study, the bioinformatics analysis firstly revealed the potential synergies towards hepatoma therapy for the associative inhibition of exportin 1 (XPO1) and ataxia telangiectasia mutated-Rad3-related (ATR), and then a super-assembled nano-pill (gold nano drug carrier loaded AZD6738 and 97-110 amino acids of apoptin (AP) (AA@G)) was constructed through camouflaging AZD6738 (ATR small-molecule inhibitor)-binding human serum albumin onto the AP-Au supramolecular nanoparticle. As expected, both in vitro and in vivo experiment results verified that the AA@G possessed extraordinary biocompatibility and enhanced therapeutic effect through inducing cell cycle arrest, promoting DNA damage and inhibiting DNA repair of hepatoma cell. This work not only provides a co-delivery strategy for intensive liver cancer treatment with the clinical translational potential, but develops a common approach to unify the pharmacokinetics of peptide and small-molecular compounds, thereby extending the scope of drugs for developing the advanced combination therapy.

Abstract
Over half of cancer patients are subjected to radiotherapy, but owing to the deficient amount of reactive oxygen radicals (ROS) and DNA double-strand breaks (DSBs), a fair number of them suffer from radiotherapy resistance and the subsequent short-term survival opportunity. To overcome it, many successes have been achieved in radiosensitizer discovery using physical strategy and/or biological strategy, but significant challenges remain regarding developing clinically translational radiosensitizers. Herein, a peptide-Au(I) infinite coordination supermolecule termed PAICS is developed that combined both physical and biological radiosensitization and possessed pharmaceutical characteristics including adequate circulatory stability, controllable drug release, tumor-prioritized accumulation, and the favorable body eliminability. As expected, monovalent gold ion endowed this supermolecule with high X-ray absorption and the subsequent radiosensitization. Furthermore, a peptide targeting CRM1, is assembled into the supermolecule, which successfully activates p53 and apoptosis pathway, thereby further sensitizing radiotherapy. As a result, PAICS showed superior ability for radiotherapy sensitization in vivo and maintained a favorable safety profile. Thus, the PAICS reported here will offer a feasible solution to simultaneously overcome both the pharmaceutical obstacles of physical and biological radiosensitizers and will enable the development of a class of nanomedicines for tumor radiotherapy sensitization.

Abstract
INTRODUCTION Chirality is immanent in nature, and chiral molecules can achieve their pharmacological action through chiral matching with biomolecules and molecular conformation recognition. OBJECTIVES Clinical translation of chiral therapeutics, particularly chiral peptide molecules, has been hampered by their unsatisfactory pharmaceutical properties. METHODS A mild and simple self-assembly strategy was developed here for the construction of peptide-derived chiral supramolecular nanomedicine with suitable pharmaceutical properties. In this proof-of-concept study, we design a D-peptide as MDM2 Self-Degradation catalysts (MSDc) to induce the self-degradation of a carcinogenic E3 Ubiquitin ligase termed MDM2. Exploiting a metal coordination between mercaptan in peptides and trivalent gold ion, chiral MSDc was self-assembled into a racemic supraparticle (MSDNc) that eliminated the consume from the T-lymphocyte/macrophage phagocytose in circulation. RESULTS Expectedly, MSDNc down-regulated MDM2 in more action than its L-enantiomer termed CtrlMSDNc. More importantly, MSDNc preponderantly suppressed the tumor progression and synergized the tumor immunotherapy in allograft model of melanoma through p53 restoration in comparison to CtrlMSDNc. CONCLUSION Collectively, this work not only developed a secure and efficient therapeutic agent targeting MDM2 with the potential of clinical translation, but also provided a feasible and biocompatible strategy for the construction of peptide supraparticle and expanded the application of chiral therapeutic and homo-PROTAC to peptide-derived chiral supramolecular nanomedicine.

Abstract
Cancer cells reprogram their metabolism to meet their growing demand for bioenergy and biosynthesis. The metabolic profile of cancer cells usually includes dysregulation of main nutritional metabolic pathways and the production of metabolites, which leads to a tumor microenvironment (TME) having the characteristics of acidity, hypoxic, and/or nutrient depletion. Therapies targeting metabolism have become an active and revolutionary research topic for anti-cancer drug development. The differential metabolic vulnerabilities between tumor cells and other cells within TME provide nanotechnology a therapeutic window of anti-cancer. In this review, we present the metabolic characteristics of intrinsic cancer cells and TME and summarize representative strategies of nanoparticles in metabolism-regulating anti-cancer therapy. Then, we put forward the challenges and opportunities of using nanoparticles in this emerging field.

Abstract
Inducing lipid peroxidation and subsequent ferroptosis in cancer cells provides a potential approach for anticancer therapy. However, the clinical translation of such therapeutic agents is often hampered by ferroptosis resistance and acquired drug tolerance in host cells. Emerging nanoplatform-based cascade engineering and ferroptosis sensitization by p53 provides a viable rescue strategy. Herein, a metallo-organic supramolecular (Nano-PMI@CeO2) toward p53 restoration and subsequent synergistic ferroptosis is constructed, in which the radical generating module-CeO2 nanoparticles act as the core, and p53-activator peptide (PMI)-gold precursor polymer is in situ reduced and assembled on the CeO2 surface as the shell. As expected, Nano-PMI@CeO2 effectively reactivated the p53 signaling pathway in vitro and in vivo, thereby downregulating its downstream gene GPX4. As a result, Nano-PMI@CeO2 significantly inhibited tumor progression in the lung cancer allograft model through p53 restoration and sensitized ferroptosis, while maintaining favorable biosafety. Collectively, this work develops a tumor therapeutic with dual functions of inducing ferroptosis and activating p53, demonstrating a potentially viable therapeutic paradigm for sensitizing ferroptosis via p53 activation. It also suggests that metallo-organic supramolecule holds great promise in transforming nanomedicine and treating human diseases.

Abstract
Biomacromolecules have long been at the leading edge of academic and pharmaceutical drug development and clinical translation. With the clinical advances of new therapeutics, such as monoclonal antibodies and nucleic acids, the array of medical applications of biomacromolecules has broadened considerably. A major on-going effort is to expand therapeutic targets within intracellular locations. Owing to their large sizes, abundant charges, and hydrogen-bond donors and acceptors, advanced delivery technologies are required to deliver biomacromolecules effectively inside cells. In this review, strategies used for the intracellular delivery of three major forms of biomacromolecules: nucleic acids, proteins, and peptides, are highlighted. An emphasis is placed on synthetic delivery approaches and the major hurdles needed to be overcome for their ultimate clinical translation.

Abstract
Luffa cylindrica (L.) is a medicinal plant associated with Cucurbitaceae family which is also known as loofah/sponge gourd, comprising a series of phytochemicals such as chlorophylls, carotenoids, oleanolic acid, saponin, and triterpenoids. The study was carried out to investigate and characterize the bioactive components of ethanolic extract of L. cylindrica. Whole fruit of L. cylindrica was collected, shade dried, pulverized, and extracted successively with ethanol by Soxhlet percolation technique. The crude extracts were later exposed to gas chromatography-mass spectrometry analysis. The profile of the extracts was analyzed for a wide range of secondary metabolites and characterized spectroscopically. A total of 18 components were identified in the ethanolic extract respectively. Prevailing pharmacologically active compounds benzaldehyde, 2-hydroxy-4-methyl-, 4-acetoxy-2-azetidinone, N-decanoic acid, oxirane,2-butyl-3-methyl-, cis, and 3,4-furandiol, tetrahydro-, cis- were present. The extracted compounds were articulated by comparing their retention time and peak area besides the interpretation of mass spectra. Thus, the current study reveals the presence of promising, bioactive components which in turn provides a strength to explore biological activity. In silico molecular docking could be performed for Alzheimer receptors and studied for its activity. Nevertheless, additional studies are required to carry out its bioactivity exploration and toxicity profile.

Abstract
Emerging protein-protein interaction (PPI) modulators have brought out exciting ability as therapeutics in human diseases, but its clinical translation has been greatly hampered by the limited affinity. Inspired by the homodimerize structure of antibody, the homodimerization contributes hugely to generating the optimized affinity is conjectured. Herein, a statistical-mechanics-theory-guided method is established to quantize the affinity of ligands with different topologies through analyzing the change of enthalpy and the loss of translational and rotational entropies. A peptide modulator for p53-MDM2 termed CPAP is used to homodimerize connecting, and this simple homodimerization can significantly increase the affinity. To realize the cellular internalization and tumor accumulation, Dimer CPAP and Mono CPAP are nanoengineered into gold(I)-CPAP supermolecule by the aurophilic interaction-driven self-assembly. Nano-Dimer CPAP potently suppressed tumor growth in lung cancer allograft model and a patient-derived xenograft model in more action than Nano-Mono CPAP, while keeping a favorable drug safety profile. This work not only presents a physico-mechanical method for calculating the affinity of PPI modulators, but also provides a simple yet robust homodimerization strategy to optimize the affinity of PPI modulators.

Abstract
Due to the unsatisfactory therapeutic efficacy and inexorable side effects of small molecule antineoplastic agents, extensive efforts have been devoted to the development of more potent macromolecular agents with high specificity. Gelonin is a plant-derived protein toxin that exhibits robust antitumor effect via inactivating ribosomes and inhibiting protein synthesis. Nonetheless, its poor internalization ability to tumor cells has compromised the therapeutic promise of gelonin. In this study, a tumor acidity-responsive intracellular protein delivery system ─ functional gelonin (Trx-pHLIP-Gelonin, TpG) composed of a thioredoxin (Trx) tag, a pH low insertion peptide (pHLIP) and gelonin, was designed and obtained by genetic recombination technique for the first time. TpG could effectively enter into tumor cells under weakly acidic conditions and markedly suppress tumor cell proliferation via triggering cell apoptosis and inhibiting protein synthesis. Most importantly, treatment by intravenous injection into subcutaneous SKOV3 solid tumors in a mouse model showed that TpG was much more effective than gelonin in curtailing tumor growth rates with negligible toxicity. Collectively, our present work suggests that the tumor acidity-targeted delivery manner endowed by pHLIP offers a new avenue for efficient delivery of other bioactive substances to acidic diseased tissues. A pH-responsive gelonin delivery platform — TpG was molecularly engineered. TpG exhibited good thermal stability and excellent serum stability. TpG enabled an efficient intracellular translocation of gelonin at pH 6.5. TpG exerted pronounced anti-proliferative effect via inducing massive apoptosis. TpG significantly delayed tumor growth with favorable in vivo biosafety profile.

Abstract
Extensive research has been undertaken in the pursuit of anticancer therapeutics. Many anticancer drugs require specificity of delivery to cancer cells, whilst sparing healthy tissue. Cell-penetrating peptides (CPPs), now well established as facilitators of intracellular delivery, have in recent years advanced to incorporate target specificity and thus possess great potential for the targeted delivery of anticancer cargoes. Though none have yet been approved for clinical use, this novel technology has already entered clinical trials. In this review we present CPPs, discuss their classification, mechanisms of cargo internalization and highlight strategies for conjugation to anticancer moieties including their incorporation into therapeutic proteins. As the mainstay of this review, strategies to build specificity into tumor targeting CPP constructs through exploitation of the tumor microenvironment and the use of tumor homing peptides are discussed, whilst acknowledging the extensive contribution made by CPP constructs to target specific protein-protein interactions integral to intracellular signaling pathways associated with tumor cell survival and progression. Finally, antibody/antigen CPP conjugates and their potential roles in cancer immunotherapy and diagnostics are considered. In summary, this review aims to harness the potential of CPP-aided drug delivery for future cancer therapies and diagnostics whilst highlighting some of the most recent achievements in selective delivery of anticancer drugs, including cytostatic drugs, to a range of tumor cells both in vitro and in vivo.

Abstract
Targeted and immunological therapy have revolutionized the malignancy treatment, but is suffering from the dose-limiting side effects and inadequate responsiveness. The emerging nanoscale infinite coordination polymers provide a feasible strategy for tumor targeting and immune sensitization. Herein, a "one-pot" self-assembled strategy based on dynamic combinatorial chemistry (DCC) principle is designed to construct a tumor-targeting metal-organic nanoparticle (MOICP) through a spontaneous co-assembling among three metal-organic coordination polymers tuned by a Wnt-inhibitor carnosic acid (CA). Responding to the tumor microenvironment, MOICP presents an optimized tumor-preferential accumulation and the satisfactory biosafety. MOICP is more active in vitro and in vivo than CA in suppressing of Wnt signaling pathway, and potently inhibits tumor growth in a patient-derived xenograft model of Wnt-activated pancreatic carcinoma. Moreover, MOICP reverses the lack of intratumoral infiltration of T lymphocytes, and hence augments the action of Anti-PD1 (programmed cell death protein 1) immunotherapy in B16F10 melanoma allograft mice model. This clinically viable MOICP can not only be applied to Wnt inhibition for cancer targeted therapy and immunotherapeutic sensitization, but also provides a de novo pattern for nanomedicine architecture with cargo-initiated co-self-assembly guided by DCC, thereby bringing new inspiration in general for disease intervention.

Abstract
Bcl-2, an anti-apoptotic protein, is always overexpressed in tumor cells to suppress the pro-apoptotic function of Bax, thereby prolonging the life of the tumor. However, BH3 proteins could directly activate Bax via antagonizing Bcl-2 to induce apoptosis in response to the stimulation. Thus, mimicking BH3 proteins with a peptide is a potential strategy for anti-cancer therapy. Unfortunately, clinical translation of BH3-mimic peptide is hindered by its inefficacious cellular internalization and proteolysis resistance. Herein, we translated a BH3-mimic peptide into a peptide-auric spheroidal nanocluster (BH3-AuNp), in which polymeric BH3-Auric precursors [Au1+-S-BH3]narein situself-assembled on the surface of gold nanoparticles by a one-pot synthesis. Expectedly, this strategy could improve the anti-proteolytic ability and cytomembrane penetrability of the BH3 peptide. As a result, BH3-AuNp successfully induced the apoptosis of two cancer cell lines by an order of magnitude compared to BH3. This therapeutic and feasible peptide nano-engineering strategy will help peptides overcome the pharmaceutical obstacles, awaken its biological functions, and possibly revive the research about peptide-derived nanomedicine.

Abstract
Nanoparticle delivery systems have good application prospects in the treatment of various diseases, especially in cancer treatment. The effect of drug delivery is regulated by the properties of nanoparticles. There have been many studies focusing on optimizing the structure of nanoparticles in recent years, and a series of achievements have been made. This review summarizes the optimization strategies of nanoparticles from three aspects-improving biocompatibility, increasing the targeting efficiency of nanoparticles, and improving the drug loading rate of nanoparticles-aiming to provide some theoretical reference for the subsequent drug delivery of nanoparticles.

Abstract
Critical challenges remain in trauma emergency and surgical procedures involving liver bleeding, particularly in perforating wounds that cannot be pressed and large wounds that cannot be sewn. Self-assembling peptide hydrogels are particularly attractive due to their intrinsic biocompatibility and programmability. Herein, we develop a nano-band-aid (NBA) through a three-stage self-assembly strategy of two functionalized peptides, which were first coassembled into nanofibers and then woven to a meshlike network driven by Ca2+. Then, catalyzed by blood coagulation factor XIIIa (FXIIIa), NBA underwent a third stage, self-assembly into a densely compacted physical barrier to stop and control the bleeding. As expected, NBA rapidly and efficiently stopped the bleeding in rat liver scratches while effectively reducing the inflammation around the wound and promoting the wound healing. This bionic self-assembly strategy will provide a clinically potential peptide-based treatment for fatal liver bleeding and reinvigorate efforts to develop self-assembling peptide hydrogels as hemostatic agents.

Abstract
In nature, cells rely on a structural framework called the "cytoskeleton" to maintain their shape and polarity. Based on this, herein a new class of cell-mimicking nanomedicine using bionic skeletons constituted by the oligomeric Au(I)-peptide complex is developed. The peptide function of degrading pathological MDM2 and MDMX is used to synthesize an oligomeric Au(I)-PMIV precursor capable of self-assembling into a clustered spherical bionic skeleton. Through coating by erythrocyte membrane, an erythrocyte-mimicking nano-cell (Nery-PMIV) is developed with depressed macrophage uptakes, increased colloidal stability, and prolonged blood circulation. Nery-PMIV potently restores p53 and p73 in vitro and in vivo by degrading MDM2/MDMX. More importantly, Nery-PMIV effectively augments antitumor immunity elicited by anti-PD1 therapy in a murine orthotopic allograft model for LUAD and a humanized patient-derived xenograft (PDX) mouse model for LUAD, while maintaining a favorable safety profile. Taken together, this work not only presents evidence showing that MDM2/MDMX degradation is a potentially viable therapeutic paradigm to synergize anti-PD1 immunotherapy toward LUAD carrying wild-type p53; it also suggests that cell-mimicking nanoparticles with applicable bionic skeletons hold tremendous promise in offering new therapies to revolutionize nanomedicine in the treatment of a myriad of human diseases.

Abstract
Tumor accumulation and intratumoral singlet oxygen (1O2) generation efficiency of photosensitizers (PSs) are two essential factors that determine their photodynamic therapy (PDT) efficacies. How to maximize the PS performance at the tumor site is of great research interest. Herein, we report a metal-organic framework (ZIF-8, ZIF = zeolitic imidazolate framework) assisted in vivo self-assembly nanoplatform, ZIF-8-PMMA-S-S-mPEG, as an effective tool for organic PS payloads to achieve efficient PDT. Using an organic PS with aggregation-induced emission as an example, under intratumoral bioreduction, PS-loaded ZIF-8-PMMA-S-S-mPEG (PS@ZIF-8-PMMA-S-S-mPEG) was self-assembled into large ordered hydrophobic clusters, which greatly enhance tumor retention and accumulation of the PS. Moreover, hydrophobic ZIF-8 assemblies greatly isolate the loaded PSs from water and improve O2 transport for the PSs to effectively produce 1O2 inside tumors under light irradiation. The organic PS is therefore endowed with optimal tumor accumulation and intratumoral 1O2 production, demonstrating the effectiveness of the developed self-assembly strategy in PDT application.

Abstract
The design of bioactive supramolecular chirality is always hampered by the lack of feasible schemes to assigned specific biological activities. Herein, we developed a "mirror-image peptide grafting" method to graft the epitopes of bioactive d-peptide onto the miniprotein template to construct a self-assembled supraparticle. Grafting DPMIβ, a 12-mer d-enantiomeric peptide functioned as the p53 agonist, onto Apamin, we successfully constructed a self-assembled d-enantiomeric miniprotein supermolecule nanoparticle, termed DMSN. This chiral supraparticle possesses a favorable pharmaceutical profile including the passive tumor targeting, cell membrane penetration, intracellular reductive responsiveness, and endosome escaping. DMSN showed in vitro and in vivo p53-dependent antiproliferative activity and augmented antitumor immunity elicited by anti-PD1 therapy. This enabling strategy will allow us to fabricate a class of peptide/protein-derived supramolecular chirality with predictable biological activities and will likely have a broad impact on the chiral nanotechnology at the service of prevention and treatment of human diseases.

Abstract
Many high-affinity peptide antagonists of MDM2 and MDMX have been reported as activators of the tumor suppressor protein p53 with therapeutic potential. Unfortunately, peptide activators of p53 generally suffer poor proteolytic stability and low membrane permeability, posing a major pharmacological challenge to anticancer peptide drug development. We previously obtained several potent dodecameric peptide antagonists of MDM2 and MDMX termed PMIs, one of which, TSFAEYWALLSP, bound to MDM2 and MDMX at respective affinities of 0.49 and 2.4 nM. Here we report the development of gold nanoparticles (Np) as a membrane-traversing delivery vehicle to carry PMI for anticancer therapy. Np-PMI was substantially more active in vitro than Nutlin-3 in killing tumor cells bearing wild-type p53, and effectively inhibited tumor growth in metastasis in a mouse homograft mode of melanoma and a patient-derived xenograft model of colon cancer with a favorable safety profile. This clinically viable drug delivery strategy can be applied not only to peptide activators of p53 for cancer therapy, but also to peptide therapeutics in general aimed at targeting intracellular protein-protein interactions for disease intervention.

Abstract
Peptide-derived nanocomposites have been exhibiting fascinating biological advantages, including but not limited to excellent biocompatibility, biological degradation, high targetability and subsequent potent therapeutic efficacy. While some successes have been achieved in the nanoengineering of peptide-based architectures with defined dimensions and medical functions, enormous challenges remain about clinical nano-pharmaceutics of peptides, especially those modulating intracellular protein-protein interactions (PPIs). Methods: We developed a general method to translate intracellular-PPI-targeted peptides into a bioavailable peptide-auric spheroidal nanohybrid (SNH), for which polymeric peptide-Auric precursors [Au1+-S-peptide]n are in-situ reduced on the surface of gold nanoseeds via a simple and mild reaction. As proofs of concept, three cytomembrane-impenetrable peptides with different physicochemical properties were successfully engineered into stable and tumor-specific SNH respectively. Results: To highlight the advantage of SNH, PMI, a hydrophobic and enzyme-intolerant peptide capable of p53 restoration, was selected to challenge the power of SNH in a colon tumor xenografts model. PMI-Au SNH in vivo suppressed tumor growth potently after three administrations: intravenous injection, intraperitoneal injection and gastric perfusion, and maintained a favorable therapeutic safety. Conclusion: This therapeutically feasible strategy of peptide nanoengineering will allow us to fabricate a series of nanomedicines to modulate carcinogenic PPIs that hide and multiply inside cells, and in all likelihood reinvigorate the development of peptide drug against wide varieties of human diseases.

Abstract
Abnormal activation of the Wnt/β-catenin signaling pathway, which underlies multiple malignancies, promotes tumor progression; drugs that can block this pathway are therefore highly attractive candidates for anticancer therapy. Using a therapeutic peptide derived from E-cadherin region V (cECRV), we sought to develop a potent and selective antagonist of β-catenin that can disrupt the carcinogenic interaction between β-catenin and BCL9. More importantly, to overcome the pharmacological obstacles of peptide-derived therapeutics (poor nuclease stability and low membrane permeability), a gold nanoparticle (AuNP)-based nanocarrier was designed to deliver cECRV into the cytoplasm to modulate the intracellular interaction of β-catenin and BCL9. The resultant nanoparticle, pAuNP-cECRV, showed no cytotoxicity towards normal peripheral blood mononuclear cells and induced cycle arrest and subsequent apoptosis of Wnt-hyperactive cancer cells by antagonizing β-catenin to inhibit the Wnt pathway. Our results indicate that pAuNP-cECRV is very promising for application as an efficient and safe peptide delivery vector for cancer therapy.

Abstract
The in situ construction of the nanoassembly has been demonstrated to improve the performance of bioactive molecules, but the control of the morphology of nanomaterials in vivo still remains a tremendous challenge. Herein, a photothermal-promoted morphology transformation (PMT) strategy is developed to accelerate the formation of nanomaterials for improving the biological performance of drug molecules. Compared with the spontaneous process, the rate of transformation increases by ∼4 times in the PMT process. Owing to increased assembly rate, the tumor accumulation of drugs is ∼2-fold than that without photo irradiation, which inhibits tumor growth effectively. More importantly, the chemical reassembly process in vitro and in vivo is monitored by the advanced ratiometric photoacoustic image, confirming the photoinduced transformation acceleration. Through the noninvasively artificial control on assembly dynamics in vivo, the PMT strategy provides a new insight for developing the intelligent theranostics.

Abstract
Intracellular protein-protein interactions (PPIs) are a vital and yet underexploited class of therapeutic targets for their crucial roles in cellular processes and involvement in disease initiation and progression. Although some successful chemistry and nanotechnologies have been introduced into peptide PPI modulators to allow cell and tissue permeability, significant challenges remain with regard to the efficient and precise modulation of PPIs within specific cells of diseased tissues, such as solid tumors. Herein, an intratumoral transformable hierarchical framework, termed iPLF, was fabricated via a two-step self-assembly between peptides and lanthanide-doped nanocrystals. In this proof-of-concept study, using NanoEL effect, TME response, and tumor marker targeting, iPLF in vivo delivered the p53-MDM2 modulator DPMI into tumor cells and β-catenin-Bcl9 modulator Bcl9p into tumor stem cells. This crafted programmed nanomedicine with triple-stage delivery and responsiveness accurately modulated the specific intracellular protein-protein interactions, resulting in the suppression of tumor growth and metastasis in vivo, while maintaining a highly favorable safety profile. iPLF reached the goal of accurate, potent, and hazard-free intracellular PPI modulation, thereby providing a means to improve current knowledge of PPI networks and a novel therapeutic strategy for a great variety of diseases.

Abstract
Nanostructures formed with bioactive peptides offer an exciting prospect in clinical oncology as a novel class of therapeutic agents for human cancers. Despite their therapeutic potential, however, peptide-based nanomedicines are often inefficacious in vivo due to low cargo-loading efficiency, poor tumor cell-targeting specificity and limited drug accumulation in tumor tissues. Here, we describe the design, via assembly of a p53-activating peptide termed PMI, functionalized PEG and fluorescent lanthanide oxyfluoride nanocrystals, of a novel nanotheranostic shaped in flexible rods. This lanthanide-peptide nanorod or LProd of bionic nature exhibited significantly enhanced tumor-targeting and -imaging properties compared to its spherical counterpart. Importantly, LProd potently inhibited tumor growth in a mouse model of human colon cancer through activating tumor suppressor protein p53 via MDM2/MDMX antagonism, while maintaining a highly favorable biosafety profile. Our data demonstrate that LProd as a multifunctional theranostic platform is ideally suited for tumor-specific peptide drug delivery with real-time disease tracking, thereby broadly impacting clinical development of antitumor peptides.

Self-Assembly of Therapeutic Peptide into Stimuli-Responsive Clustered Nanohybrids for Cancer-Targeted Therapy. ADVANCED FUNCTIONAL MATERIALS 2019; 29:1807736.

Abstract
Clinical translation of therapeutic peptides, particularly those targeting intracellular protein-protein interactions (PPIs), has been hampered by their inefficacious cellular internalization in diseased tissue. Therapeutic peptides engineered into nanostructures with stable spatial architectures and smart disease targeting ability may provide a viable strategy to overcome the pharmaceutical obstacles of peptides. This study describes a strategy to assemble therapeutic peptides into a stable peptide-Au nanohybrid, followed by further self-assembling into higher-order nanoclusters with responsiveness to tumor microenvironment. As a proof of concept, an anticancer peptide termed β-catenin/Bcl9 inhibitors is copolymerized with gold ion and assembled into a cluster of nanohybrids (pCluster). Through a battery of in vitro and in vivo tests, it is demonstrated that pClusters potently inhibit tumor growth and metastasis in several animal models through the impairment of the Wnt/β-catenin pathway, while maintaining a highly favorable biosafety profile. In addition, it is also found that pClusters synergize with the PD1/PD-L1 checkpoint blockade immunotherapy. This new strategy of peptide delivery will likely have a broad impact on the development of peptide-derived therapeutic nanomedicine and reinvigorate efforts to discover peptide drugs that target intracellular PPIs in a great variety of human diseases, including cancer.

Abstract
The use of nanoparticles as drug carriers has provided a powerful weapon in the fight against cancer. These nanocarriers are able to transport drugs that exhibit very different nature such as lipophilic or hydrophilic drugs and big macromolecules as proteins or RNA. Moreover, the external surface of these carriers can be decorated with different moieties with high affinity for specific membrane receptors of the tumoral cells to direct their action specifically to the malignant cells. The selectivity improvement yielded by these nanocarriers provided a significative enhancement in the efficacy of the transported drug, while the apparition of side effects in the host was reduced. Additionally, it is possible to incorporate targeting moieties selective for organelles of the cell, which improves even more the effect of the transported agents. In the last years, more sophisticated strategies such as the use of switchable, hierarchical or double targeting strategies have been proposed for overcoming some of the limitations of conventional targeting strategies. In this review, recent advances in the development of targeted nanoparticles will be described with the aim to present the current state of the art of this technology and its huge potential in the oncological field.
