Abstract Breast cancer is a complex and heterogeneous disease, encompassing various subtypes characterized by distinct molecular features, clinical behaviors, treatment responses. Categorization of based on the presence or absence estrogen receptor (ER), progesterone (PR), human epidermal growth factor 2 (HER2), leading to such as luminal A, B, HER2-positive, triple-negative breast (TNBC). TNBC, comprising around 20% all cancers, lacks expression ER, PR, HER2 receptors, rendering it unresponsive targeted therapies presenting significant challenges in treatment. TNBC associated with aggressive behavior, high rates recurrence, resistance chemotherapy. Tumor initiation, progression, are attributed stem cells (BCSCs), which possess self-renewal, differentiation, tumorigenic potential. Surface markers, self-renewal pathways (Notch, Wnt, Hedgehog signaling), apoptotic protein (Bcl-2), angiogenesis inhibition (VEGF inhibitors), immune modulation (cytokines, checkpoint inhibitors) among key targets discussed this review. However, targeting BCSC subpopulation presents challenges, including off-target effects, low solubility, bioavailability anti-BCSC agents. Nanoparticle-based offer promising approach target cellular processes implicated survival BSCS TNBC. In review, we explore nanocarrier-based approaches for BCSCs aiming overcome these improve outcomes patients. These nanoparticle-based therapeutic strategies hold promise addressing gap delivering while minimizing systemic toxicity enhancing efficacy. Graphical abstract

Triple-negative breast cancer (TNBC) presents a global health challenge due to its aggressive behavior and limited treatment options. This study explores novel therapeutic strategy using C-peptide-conjugated solid lipid nanoparticles (C-peptide-SLNs) for targeting paclitaxel (PTX) delivery in TNBC treatment. C-peptide, derived from endostatin, enhances efficacy by overexpressed integrin αvβ3 receptors on cells. Characterization confirmed suitable particle size, stability, encapsulation efficiency over 90%, with favorable release profiles acidic tumor environments. In vitro, C-peptide-SLN-PTX markedly improved cytotoxicity against 4T1 carcinoma cells, an IC50 of 1.2 µg/mL, compared 3.4 µg/mL SLN-PTX 8.9 free PTX. Wound-healing assays verified significant inhibition cell migration MDA-MB-231 lines. Flow cytometry αv C-peptide-SLN-PTX. vivo studies tumor-bearing mice showed 82% volume reduction prevented pulmonary metastasis, normal liver enzyme levels indicating reduced toxicity. PET imaging revealed decreased metabolic activity treated groups, immunohistochemical analyses demonstrated superior antitumor Ki-67 expression apoptosis induction (p53 upregulation, Bcl-2 downregulation). These findings highlight the potential C-peptide-SLNs as effective targeted PTX system TNBC, offering promising avenues enhancing strategies.

Targeting the influencing factors in tumor growth and expansion microenvironment is one of key approaches to cancer immunotherapy. Various can cooperation stimulate growth, suppress anti-tumor immune responses, promote drug resistance, ultimately enhance recurrence. Therefore, due dependence close these axes, their combined targeting have a greater effect compared individual targeting. Among important affecting region, CD73 EGFR play an role by stimulating each other's expression function. we intended use nanocarriers that had previously produced characterized deliver anti-CD73 siRNAs murine breast 4T1 cells. Silencing could significantly induce cell death Downregulation CD73/EGFR axis also suppressed migratory proliferative potential This therapeutic strategy inhibited ovo model. These findings imply simultaneous be considered novel immunotherapeutic approach needs further investigation future studies.

The Golgi apparatus is widely considered a secretory center and hub for different signaling pathways. Abnormalities in dynamics can perturb the tumor microenvironment influence cell migration. Therefore, unraveling regulatory network of searching pharmacological targets would facilitate development novel anticancer therapies. Previously, we reported an unconventional role tethering factor golgin-97 inhibiting breast motility, its downregulation was associated with poor patient prognosis. However, specific mechanism cancer progression vivo remain unclear. We integrated genetic knockout (KO) golgin-97, animal models (zebrafish xenograft mice), multi-omics analysis (next-generation sequencing proteomics), bioinformatics analysis, kinase inhibitor treatment to evaluate effects KO triple-negative cells. Gene knockdown followed by qRT‒PCR, Western blotting, viability, migration, cytotoxicity assays were performed elucidate mechanisms KO-mediated invasion. A mouse model used investigate drug therapy. demonstrated that promoted metastasis zebrafish models. Multi-omics revealed Wnt pathway, MAPK cascades, inflammatory cytokines are involved KO-induced progression. Targeting ERK1/2 p38 pathways effectively attenuated golgin-97-induced reduced expression mediators, enhanced chemotherapeutic effect paclitaxel vitro vivo. Specifically, compared regimen, combination inhibitors significantly prevented lung injury. further hypoxia physiological condition reduces cancer, revealing potential feedback loop between ERK/MAPK golgin-97. Our results collectively support microenvironment, possibly providing new insights anti-breast development.
