Objectives Triphenylphosphine (TPP) and Doxorubicin (DOX) were conjugated to obtain Triphenylphosphine-Doxorubicin (TPP-DOX), which was applied in tumor cells for enhancement of DOX in mitochondria targeting. The study focused on investigating the anti-tumor effect of TPP-DOX in combination with radiotherapy throughout in vitro and in vivo studies. Methods TPP-DOX was synthesized using the carbodiimide method. In vitro experiments were conducted with 4T1 cells (mouse breast cancer cell line) to assess apoptosis induction, mitochondrial targeting, reactive oxygen species (ROS) production, and mitochondrial membrane potential. The research evaluates the effects of TPP-DOX, DOX, and their combinations with radiotherapy. A nude mouse tumor heterograft model was established to investigate the synergistic effect of TPP-DOX and radiotherapy. Results TPP-DOX was successfully synthesized and scrupulously verified. In vitro experiments showed that compared to DOX, TPP-DOX exhibited enhanced tumor cytotoxicity, improved cellular uptake in 4T1 cells, and increased apoptosis induction. Combined with radiotherapy, TPP-DOX promoted mitochondrial ROS production, reduced mitochondrial membrane potential, and amplified its anti-tumor effect. In vivo experiment confirmed that TPP-DOX combined with radiotherapy exhibited superior anti-tumor activity, promoted tumor tissue apoptosis, inhibited tumor angiogenesis, and showed a favorable in vivo safety profile. Conclusion The study confirmed that when combined with radiotherapy, TPP-DOX promoted tumor cell apoptosis, and effectively enhanced the anti-tumor effect. In sensitive cells, TPP-DOX demonstrates comparable efficacy to DOX when combined with radiotherapy. TPP-DOX holds significant potential for a broader spectrum of applications and emerges as a valuable candidate for clinical application. These findings provide a promising and efficient therapeutic strategy for tumor treatment with improved efficacy and safety.

Regulatory guidance requires the quantification of encapsulated and free doxorubicin for a liposomal doxorubicin injection bioequivalence study. Due to the instability of liposome formulations in plasma samples, the release of free drug from the liposomal encapsulated doxorubicin during sample handling would result in elevation of measured free doxorubicin concentration. To prevent the potential release of free drug, stabilizer reagents and procedures were successfully developed and validated to adequately stabilize liposomal drugs in plasma samples during sample collection, storage and extraction. Three LC–MS/MS methods were developed and fully validated for direct quantitation of free, encapsulated and total doxorubicin concentrations in human plasma according to relevant regulatory guidance: Method 1: Quantitation of free doxorubicin and doxorubicinol at a linear range of 1−400 ng/mL and 0.5−10 ng/mL, respectively, from stabilizer treated plasma samples using solid phase extraction (SPE); Method 2: Quantitation of encapsulated doxorubicin at a linear range of 50−50,000 ng/mL from the stabilizer treated plasma sample using SPE followed by PPE extraction method; Method 3: Quantitation of total concentration of doxorubicin from untreated plasma samples at a linear range of 50−50,000 ng/mL using PPE. All three methods were successfully used to support a bioequivalence study between Caelyx® and Duomeisu® (Doxorubicin Hydrochloride Liposomal injection, generic doxorubicin formulation produced by CSPC). Incurred sample reanalysis (ISR) passing rate for total doxorubicin, free doxorubicin/doxorubicinol, and encapsulated doxorubicin methods were 100 %, 84.7 %/100 %, and 98.5 %, respectively. The measured total doxorubicin concentrations matched the sum of free and encapsulated doxorubicin concentrations.

The rapid development of treatment resistance in tumors poses a technological bottleneck in clinical oncology. Ferroptosis is a form of regulated cell death with clinical translational potential, but the efficacy of ferroptosis-inducing agents is susceptible to many endogenous factors when administered alone, for which some cooperating mechanisms are urgently required. Here, we report an amorphous calcium carbonate (ACC)–based nanoassembly for tumor-targeted ferroptosis therapy, in which the totally degradable ACC substrate could synergize with the therapeutic interaction between doxorubicin (DOX) and Fe2+. The nanoplatform was simultaneously modified by dendrimers with metalloproteinase-2 (MMP-2)–sheddable PEG or targeting ligands, which offers the functional balance between circulation longevity and tumor-specific uptake. The therapeutic cargo could be released intracellularly in a self-regulated manner through acidity-triggered degradation of ACC, where DOX could amplify the ferroptosis effects of Fe2+ by producing H2O2. This nanoformulation has demonstrated potent ferroptosis efficacy and may offer clinical promise.

The side effects of doxorubicin (DOX) extremely limit its application in the treatment of malignant tumors. Nano-sized polymeric drugs based on the acidic microenvironment of tissular- or intra- tumor have attracted ample attention because of their potential in reducing side effects. In this research, an amphiphilic diblock copolymer based on poly (ethylene glycol) (PEG) and functionalized polycaprolactone (PCL) was synthesized and utilized as the drug carrier. DOX was chemically conjugated with the polymer via acid-cleavable imine bonds to obtain a novel pH-sensitive DOX prodrug (mPEG-PCL-Imi-DOX). mPEG-PCL-Imi-DOX (24.2 wt % DOX content) formed micelles with an average diameter of 125 nm through a simple solvent evaporation method. The in vitro release profile demonstrated that DOX release of the prodrug micelles was pH-responsive and able to be accelerated with the decrease of pH. In vitro cytotoxicity assay tests revealed that the pH-sensitive DOX prodrug micelles exhibited relatively lower toxicity and similar antitumor efficacy towards MCF-7 cells compared with free DOX. Hence, the DOX prodrug micelles with imine bonds can offer a carrier with great potential for chemo-therapeutics.Keywords:doxorubicin;pH-sensitive;prodrug;micelles;imine

Marine ascidian is becoming one of the main sources of an antitumor drug that has shown high bioactivity and extensive application in cancer treatment.Halocynthia roretzi, an edible marine sea squirt, has been demonstrated to have various kinds of biological activities, such as anti-diabetic, anti-hypertension, and enhancing immunity. In this study, we reported that aqueous extracts from the edible parts ofH. roretzipresented significantly inhibiting the efficiency on HepG-2 cell viability. The separate mixed compound exhibited strong effects of inhibitory proliferation and induced apoptosis via the generation of ROS along with the concurrent loss of mitochondrial membrane potential on tumor cells. Furthermore, we found that there existed a significantly synergistic effect of the ascidian-extracted compound mixture with the anti-cancer drug doxorubicin. In the presence of the extracts fromH. roretzi, the dose of doxorubicin at the cellular level could be reduced by a half dose. The extracts were further divided by semipreparative-HPLC and the active ingredients were identified as a mixture of fatty amide, which was composed of hexadecanamide, stearamide, and erucamide by UHPLC-MS/MS. Our results suggest that the potential toxicity of ascidianH. roretziin tumor cells, and the compounds extracted fromH. roretzicould be potentially utilized on functional nutraceuticals or as an adjunct in combination with chemotherapy.Keywords:ascidian;Halocynthia roretzi;anti-tumor;drug combination;doxorubicin

Hepatocellular carcinoma (HCC) is one of the greatest public health problems worldwide, and chemotherapy remains the major approach for the HCC treatment. Doxorubicin (DOX) is one of the anthracycline antibiotics but its clinical use is limited due to its severe cardiotoxicity. In this study, novel hybrid nanoparticles by self-assembling based on pectin-doxorubicin conjugates (PDC-NPs) were fabricated for HCC treatment. The stabilized structure of the PDC-NPs was characterized by methylene blue absorption, the size, zeta potential and the morphology, which was investigated by Zetasizer nanoparticle analyzer and transmission electron microscope (TEM), of nanoparticles. The PDC-NPs achieved a sustained and prolonged release ability, which was illustrated with in vitro drug release profiles, anti-cell proliferation study, cellular uptake assay and in vivo pharmacokinetics analysis. Biocompatibility of the PDC-NPs was assessed with bovine serum albumin (BSA) adsorption test, hemolysis activity examination and viability evaluation of human umbilical vein endothelial cells. Importantly, in vivo studies of the PDC-NPs, which were performed in the athymic BALB/c nude mice, demonstrated that the PDC-NPs significantly reduced the lethal side effect of DOX. Additionally, the H&E staining and serum biochemistry study further confirmed the excellent biological security of the PDC-NPs.

Doxorubicin (DOX) is a chemotherapy drug used for hepatocellular carcinoma (HCC) treatment, but its effectiveness can be dramatically dampened by cancer cell chemoresistance. Signal transducer and activator of transcription 3 (STAT3) is implicated with drug resistance in a range of cancers (e.g., HCC), and the STAT3 inhibition can reverse the resistance of cancer cells to chemotherapeutic drugs. In the present study, a combination regimen to improve the efficiency of DOX was provided via the STAT3 blockade using plumbagin (PLB). A poly(lactic-co-glycolic acid) decorated by polyethylene glycol and aminoethyl anisamide was produced in the present study with the hope of generating the nanoparticles for co-delivery of DOX and PLB. The resulting co-formulation suppressed the STAT3 activity and achieved the synergistic chemotherapy, which led to tumor inhibition in the mice with subcutaneous DOX-resistant HCC, without causing any toxicity. The present study reveals the synergism of DOX and PLB, and demonstrates a promising combinatorial approach for treating HCC.

Previous study has confirmed that hsa_circ_0092276 is highly expressed in doxorubicin (DOX)-resistant breast cancer cells, indicating that hsa_circ_0092276 may be involved in regulating the chemotherapy resistance of breast cancer. Here we attempted to investigate the biological role of hsa_circ_0092276 in breast cancer. We first constructed DOX-resistant breast cancer cells (MCF-7/DOX and MDA-MB-468/DOX). The 50% inhibiting concentration of MCF-7/DOX and MDA-MB-468/DOX cells was significantly higher than that of their parental breast cancer cells, MCF-7 and MDA-MB-46. MCF-7/DOX and MDA-MB-468/DOX cells also exhibited an up-regulation of drug resistance-related protein MDR1. Compared with MCF-7 and MDA-MB-46 cells, hsa_circ_0092276 was highly expressed in MCF-7/DOX and MDA-MB-468/DOX cells. Hsa_circ_0092276 overexpression enhanced proliferation and the expression of LC3-II/LC3-I and Beclin-1, and repressed apoptosis of breast cancer cells. The effect of hsa_circ_0092276 up-regulation on breast cancer cells was abolished by 3-methyladenine (autophagy inhibitor). Hsa_circ_0092276 modulated autophagy-related gene 7 (ATG7) expression via sponging miR-384. Hsa_circ_0092276 up-regulation promoted autophagy and proliferation, and repressed apoptosis of breast cancer cells, which was abolished by miR-384 overexpression or ATG7 knockdown. In addition, LV-circ_0092276 transfected MCF-7 cell transplantation promoted autophagy and tumor growth of breast cancer in mice. In conclusion, our data demonstrate that hsa_circ_0092276 promotes autophagy and DOX resistance in breast cancer by regulating miR-348/ATG7 axis. Thus, this article highlights a novel competing endogenous RNA circuitry involved in DOX resistance in breast cancer.

Simple SummaryBreast cancer is a disease that begins in the cells of the breast. Although it is most common in women, it can also occur in men, though this is rare. Early detection and treatment are crucial to improving outcomes and survival rates. Risk factors include age, family history, certain gene mutations, prior history of breast cancer, exposure to estrogen, and lifestyle habits like alcohol consumption and inactivity. Symptoms include changes in the skin on the breast, such as dimpling, lumps or thickening, changes in size or shape, and discharge from the nipple. Diagnosis is often made through a clinical breast exam, mammogram, biopsy, and possibly additional imaging tests. Treatment options include surgery, chemotherapy, radiation therapy, hormone therapy, and targeted therapy. The choice of treatment method depends on the stage and characteristics of cancer.AbstractBreast cancer is considered the solid tumor most sensitive to chemotherapy. However, it can become resistant to various chemotherapeutic drugs, including doxorubicin, which triggers cell death by intercalation between DNA bases, free radical formation, and topoisomerase II inhibition. When drug resistance develops, several miRNAs are dysregulated, suggesting that miRNAs may play a significant role in resistance formation. In the current study, we investigated how doxorubicin sensitivity of breast cancer cells is affected by miR-153-3p and its target gene. The MTT method was used to determine the chemo-sensitizing effect of miR-153-3p on doxorubicin in MCF-7 and MDA-MB-231 cell lines. Results of Western blot and dual luciferase confirmed that miR-153-3p targets KIF20A and decreases its expression. Transwell and flow cytometry experiments showed that miR-153-3p and doxorubicin together had higher effects on MCF-7 and MDA-MB-231 cell proliferation, migration, and invasion, as well as increasing apoptosis and arresting cells in the G1 phase. Proteins related to apoptosis and the cell cycle exhibited the same tendency. Intracellular vesicle formation was inhibited and RAB26 was also downregulated by treatment with miR-153-3p alone or in combination with doxorubicin. Doxorubicin’s ability to suppress tumors may be enhanced by miR-153-3p, according to in vivo studies. According to our findings, miR-153-3p has a direct effect on KIF20A and may regulate the formation of intracellular vesicles, which in turn makes breast cancer cells more susceptible to doxorubicin.Keywords:miR-153-3p;chemosensitivity;breast cancer;doxorubicin;KIF20A

The cancer-associated fibroblasts (CAFs) in tumor stroma present substantial barriers to drug penetration, resulting in tumor resistance and progression. One promising strategy is to reprogram CAFs into a quiescent state, which necessitates novel approaches. Our study introduces a sequential treatment strategy using chitosan thermosensitive hydrogels loaded with α-Mangostin (α-M), a small molecule drug with antifibrotic properties, aimed at reprogramming CAFs within the breast cancer tumor microenvironment (TME). We developed glutathione (GSH)-responsive nanoparticles (NPc) that carry the chemotherapeutic drug doxorubicin (DOX). Treatment with α-M results in the downregulation of CAF-specific biomarkers and a remodeled TME, which improves the penetration of NPc/DOX deep into the tumor tissue. This strategy holds great promise in enhancing cancer therapeutic outcomes in tumors rich in CAFs, particularly in the case of breast cancer.

Bone metastasis secondary to breast cancer negatively impacts patient quality of life and survival. The treatment of bone metastases is challenging since many anticancer drugs are not effectively delivered to the bone to exert a therapeutic effect. To improve the treatment efficacy, we developed Pluronic P123 (P123)-based polymeric micelles dually decorated with alendronate (ALN) and cancer-specific phage protein DMPGTVLP (DP-8) for targeted drug delivery to breast cancer bone metastases. Doxorubicin (DOX) was selected as the anticancer drug and was encapsulated into the hydrophobic core of the micelles with a high drug loading capacity (3.44%). The DOX-loaded polymeric micelles were spherical, 123 nm in diameter on average, and exhibited a narrow size distribution. The in vitro experiments demonstrated that a pH decrease from 7.4 to 5.0 markedly accelerated DOX release. The micelles were well internalized by cultured breast cancer cells and the cell death rate of micelle-treated breast cancer cells was increased compared to that of free DOX-treated cells. Rapid binding of the micelles to hydroxyapatite (HA) microparticles indicated their high affinity for bone. P123-ALN/DP-8@DOX inhibited tumor growth and reduced bone resorption in a 3D cancer bone metastasis model. In vivo experiments using a breast cancer bone metastasis nude model demonstrated increased accumulation of the micelles in the tumor region and considerable antitumor activity with no organ-specific histological damage and minimal systemic toxicity. In conclusion, our study provided strong evidence that these pH-sensitive dual ligand-targeted polymeric micelles may be a successful treatment strategy for breast cancer bone metastasis.

A novel strategy to construct a therapeutic system based on functionalized AuNPs which can specifically respond to tumor microenvironment was reported. In the therapeutic system, doxorubicin was conjugated to AuNPs via thiol–Au bond by using a peptide substrate, CPLGLAGG, which can be specifically cleaved by the protease. In vivo study shows that after injection of the functionalized AuNPs to the tumor-bearing mice, the over-expressed protease of MMP-2 in tumor tissue and intracellular GSH can lead to the rapid release of the anti-tumor drug (doxorubicin) from the functionalized AuNPs to inhibit tumor growth and realize fluorescently imaging simultaneously. The functionalized AuNPs with tumor-triggered drug release property can further improve the efficacy and reduce side effects significantly.
