Co-delivery of anti-cancer agents within pH-sensitive polymeric micelles could provide superior advantages over the co-administration of free drugs, since it enables simultaneous delivery of drugs to reach an optimum synergistic dose right to the tumor. DOX was conjugated to the polymer through a hydrazine linker by Schiff’s base reaction. Then, DTX was encapsulated into the core of the polymer to the resulting DOX-Hyd-PM/DTX micelle with optimum molar ratios of 1:1 and 1:5 (DOX/DTX). The final formulations showed the desired particle size and increased release of DOX and DTX in acidic media (pH 5.5). The cytotoxicity assay of DOX-Hyd-PM/DTX indicated the highest synergistic effect on both 4T1 and TUBO cell lines over other formulations. Interestingly, in accordance with in vitro results, DOX-Hyd-PM/DTX revealed a promising anti-tumor activity in mice-bearing 4T1 breast cancer tumor with higher tumor accumulation of DOX and DTX after 24 h compared to free drugs combination. These findings point to the potential use of such smart nanodrug delivery systems in cancer treatment, where the synergistic effect of both drugs may be used to enhance therapeutic response.

Therefore, a biocompatible and efficient polylactic-co-glycolic acid (PLGA: P)- poly-ε-caprolactone (PCL: P) copolymer was fabricated for delivery of relatively insoluble curcumin (Cur) to A549 lung cancer cells. Next, the physicochemical aspects of the synthesized nanobeads were characterized by applying analytical sets, including FT-IR, DLS, TEM, and TGA as nano-metric size (20–45 nm) and 1.29% of Cur entrapment efficiency were determined for P-P-Cur nano-beads. Thereafter, a controlled (5% within 2 h at pH 7.4) and pH-sensitive (nearly 50% within 4 h at pH 5.0) drug release manner was observed for P-P-Cur nanobeads. Thereafter, biomedical assays were conducted for the cancer suppression ability of nanobeads. 41% cell viability after 24 h of treatment with 200 nM concentration and 7.55% cell cycle arrest at 5 h of post-treatment with 100 nM (IC50) concentration were attained for P-P-Cur. Also, 7-fold increase and 2-fold decrease in the expressions of Caspase-9 (apoptotic gene) and Bcl2 (anti-apoptotic gene) were observed which have further approved the cancer inhibition potency of the P-P-Cur sample. The cellular uptake results indicated 91% internalization in A549 cells while it was less than 1% for the pure Cur.

However, due to the immunosuppressed microenvironment of pancreatic ductal adenocarcinoma (PDAC), the TAAs released by PTT are difficult to induce an effective immune response. In this work, we prepared the mesoporous silica (mSiO2) coated black titanium dioxide (bTiO2) photothermal nanoparticles (NPs) for enhanced photothermal-immunotherapy toward PDAC, in which resiquimod (R848) was loaded and DOTA-Gd was conjugated. The NPs are specified as bTiO2@mSiO2@Gd/R848 and abbreviated to NPs/R848. R848 as a kind of Toll-like receptor 7/8 agonist can remodel the tumor microenvironment (TME) in PDAC and induce a strong immune response. Furthermore, DOTA-Gd serves as a magnetic resonance imaging (MRI) contrast agent to improve the T1-weighted MRI performance of the NPs. In vitro results of this study show that NPs/R848 could thermally ablate tumor cells and efficiently trigger dendritic cell (DC) maturation. The results of in vivo investigations demonstrate that the combined use of photothermal-immunotherapy exhibits a significant inhibitory effect on tumor growth. Besides, it promoted maturation of DCs and enhanced infiltration of CD8 + , CD4 + T cells to improve the TME in PDAC. Our study anticipates that by encouraging the maturation of DCs, this strategy will improve the TME and enable the successful photothermal-immunotherapy of PDAC.","PeriodicalId":9408,"journal":{"name":"Cancer Nanotechnology","volume":"43 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141254113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the average size of liposomes ~ 100 nm leads to liposomes being susceptible to hepatic and renal metabolism to excretion outside the body leading to poor drug delivery efficiency with a total utilization rate of less than 0.7%, resulting in unfavorable treatment outcomes. We have developed a novel liposome platform equipped with tumor surface nucleolin-targeting capacity to enhance drug accumulation at the tumor in vivo. The encapsulation of doxorubicin through thin film hydration has resulted in the formation of D@L-AS1411. Through in vivo experiments, we have demonstrated the effective accumulation of D@L-AS1411 at the tumor site and its ability to improve doxorubicin utilization rates by 40%. Additionally, D@L-AS1411 induces immunogenic death of tumor cells, release of tumor-associated antigens, upregulation of calreticulin expression, and recruitment of active T cell infiltration, and ultimately improves the therapeutic efficacy against tumors (70%). Based on the nucleic acid aptamer AS1411, D@L-1411 is developed to specifically enhance the accumulation of Dox at tumor sites, thereby inhibiting and enhancing the anti-tumor effect. In summary, this study not only provides an efficient tumor-targeting delivery platform but also contributes to the improvement of chemotherapy–immunotherapy combination for tumor treatment strategy in the clinic.","PeriodicalId":9408,"journal":{"name":"Cancer Nanotechnology","volume":"2016 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notch1 silencing repressed proliferation and facilitates apoptosis of resistant CRC cells, and suppressed glycolysis and promoted pyroptosis in resistant CRC cells. Notch1 directly interacts with PCAF. Notch1 knockdown’s suppressive effect on glycolysis was reversed by overexpression of PCAF. Moreover, a nanocarrier called PLAG NPs was built with a higher delivery efficiency compared with lipo2000. Si-Notch1 delivered by PLAG NPs efficiently overcame the CRC cells’ 5-FU resistance and facilitated pyroptosis in a CRC mouse model.

Traditional chemotherapy, while effective, often results in significant side effects, highlighting the need for more efficient cancer therapies. Recent advancements in nanotechnology have led to the development of strategies that aim to minimize toxicity to normal cells by more precise targeting of cancer cells. In this context, cobalt oxide nanoparticles (Co3O4 NPs) have shown promising anticancer potential. Our study focuses on evaluating the antioxidant, antibacterial, and anticancer properties of Co3O4 NPs synthesized using Vibrio sp. VLC, a bioluminescent bacterium. XRD and FTIR analyses confirmed the successful synthesis of Co3O4 NPs, which displayed spherical morphology with an average diameter of 60 nm. The nanoparticles demonstrated significant antioxidant and antibacterial activities. The MTT assay indicated that the NPs caused dose- and time-dependent toxicity against CT26 cells, while exhibiting relatively lower toxicity towards normal cells. In vivo experiments further confirmed the significant tumor suppressive effects in BALB/c mice, with minimal side effects on the liver, spleen, and kidney tissues compared to the widespread toxicity of cisplatin. This study verifies the successful synthesis of Co3O4 NPs and their potent antioxidant, antibacterial, and anticancer activities. The biosynthesized Co3O4 NPs represent a promising targeted method for CRC therapy.

Given that hypobaric hypoxia and hyperbaric oxygen exposure can significantly change pharmacokinetics of drugs, it is interesting to determine whether they can regulate tissue distribution of nanomedicine, especially in tumor, for enhanced cancer therapy. Hypobaric hypoxia exposure improved the pharmacokinetics of paclitaxel-loaded liposomes and facilitated their distribution in the heart and liver, whereas hyperbaric oxygen exposure did not benefit and even impaired the pharmacokinetics and distribution. Particularly, both hypobaric hypoxia and hyperbaric oxygen exposure could not improve the distribution in subcutaneous tumor. Thus, we constructed orthotopic liver tumor model and discussed whether high distribution of the liposomal nanomedicine in the liver, facilitated by hypobaric hypoxia exposure, could ensure their effective accumulation in liver tumor for enhanced cancer therapy. The liposomal nanomedicine with adjuvant hypobaric hypoxia exposure significantly inhibited the growth of orthotopic liver tumor for prolonged survival time, achieved by hypobaric hypoxia-promoted accumulation at tumor sites of the liver. It might be the first example of the application of adjuvant intermittent hypobaric hypoxia exposure in treating liver cancer.","PeriodicalId":9408,"journal":{"name":"Cancer Nanotechnology","volume":"17 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140586144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, combination therapy using pathway inhibitors has been plagued by an inability to administer doses sufficient to achieve clinical benefit due to synergistic toxicities. Here we sought to combine nanoformulations of the PARPi talazoparib, nTLZ, and the CDKi dinaciclib, nDCB, in a nano-cocktail to enhance therapeutic efficacy while maintaining lower doses. Pharmacokinetics of nDCB were assessed to ensure it is compatible with nTLZ. nDCB was combined with nTLZ to generate a nano-cocktail nDCB:nTLZ, which elicits greater cell death in vitro compared to the combination of the free drugs. MDA-MB-231-LUC-D3H2LN xenografts were utilized to assess therapeutic efficacy of the nano-cocktail in terms of tumor progression. Administration of the nano-cocktail significantly slowed tumor progression in the HR proficient animal model compared to administration of free talazoparib and free dinaciclib at the same doses. Histology of the liver, spleen, and kidneys revealed long-term treatment did not induce nanoparticle associated morphological changes. Complete blood count did not reveal any significant hematologic changes after treatment with either the free combination or nano-cocktail. The efficacy and toxicity data suggest that further dose escalation can be pursued in order to achieve a stronger response. These data suggest the administration of combination therapy through the nano-cocktail leads to a better response than the use of free compounds and is a promising strategy for implementing combination therapy in the clinic.","PeriodicalId":9408,"journal":{"name":"Cancer Nanotechnology","volume":"102 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2024-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140199659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
