Pancreatic cancer is one of the most aggressive forms cancer, and treatment options are limited. One therapeutic approach to use nanoparticles deliver active agent directly pancreatic cells. Nanoparticles can be designed specifically target cells, minimizing damage healthy tissues. Silver have unique ability absorb light, especially in near-infrared (NIR) region. In this study, silver functionalized with IgG molecules were synthesized administered cell lines. Subsequently, cells photo-excited using a 2 W 808 nm laser further examined PANC-1 Flow cytometry confocal microscopy combined immunochemical staining used examine interaction between The photothermal therapy based on IgG-functionalized induces dysfunction Golgi apparatus, leading activation caspase-3 apoptotic pathway ultimately resulting cellular apoptosis. These findings suggest that our proposed nanoparticle could emerge as novel for cancer.

Pancreatic cancer is fast becoming a global menace and it projected to be the second leading cause of cancer-related death by 2030. adenocarcinomas, which develop in pancreas’ exocrine region, are predominant type pancreatic cancer, representing about 95% total tumors. The malignancy progresses asymptomatically, making early diagnosis difficult. It characterized excessive production fibrotic stroma known as desmoplasia, aids tumor growth metastatic spread remodeling extracellular matrix releasing factors. For decades, immense efforts have been harnessed toward developing more effective drug delivery systems for treatment leveraging nanotechnology, immunotherapy, conjugates, combinations these approaches. However, despite reported preclinical success approaches, no substantial progress has made clinically prognosis worsening. This review provides insights into challenges associated with therapeutics discusses strategies minimize adverse effects current chemotherapy options improve efficiency treatment.

The incorporation of transition metal catalysts (TMCs) into nanoscaffolds generates nanocatalysts that replicate key aspects enzymatic behavior. TMCs can access bioorthogonal chemistry unavailable to living systems. These nanozymes be employed as in situ "factories" for generating bioactive molecules where needed. generation effective requires co-engineering the TMC and nanometric scaffold. This review presents an overview recent advances field nanozymes, focusing on modular design both nanomaterial catalyst how they synergistically work together uncaging imaging therapeutic agents.

The combination of cuproptosis and immune checkpoint inhibition has shown promise in treating malignant tumors. However, it remains a challenge to deliver copper ions inhibitors efficiently simultaneously Herein, mitochondria-targeted nanoscale coordination polymer particle, Cu/TI, comprising Cu(II), triphenylphosphonium conjugate 5-carboxy-8-hydroxyquinoline (TI), for effective induction programmed cell death-1 (PD-L1) downregulation is reported. Upon systemic administration, Cu/TI accumulates tumor tissues induce immunogenic cancer death reduce PD-L1 expression. Consequently, promotes the intratumoral infiltration activation cytotoxic T lymphocytes greatly inhibit progression colorectal carcinoma triple-negative breast mouse models without causing obvious side effects.

Gemcitabine, a pivotal chemotherapeutic agent for pancreatic ductal adenocarcinoma (PDAC), frequently encounters drug resistance, posing significant clinical challenge with implications PDAC patient prognosis. In this study, employing an integrated approach involving bioinformatic analyses from multiple databases, we unveil CSNK2A1 as key regulatory factor. The patient-derived xenograft (PDX) model further substantiates the critical role of in gemcitabine resistance within context PDAC. Additionally, targeted silencing expression significantly enhances sensitivity cells to treatment. Mechanistically, CSNK2A1's transcriptional regulation is mediated by H3K27 acetylation Moreover, identify activator autophagy, and enhanced autophagy drives resistance. Silmitasertib, established inhibitor, can effectively inhibit autophagy. Notably, combinatorial treatment Silmitasertib demonstrates remarkable efficacy treating summary, our study reveals potent predictive factor inhibition represents promising therapeutic strategy restore PDAC, offering hope improved outcomes.

Abstract Despite remarkable achievements in cancer immunotherapy, significant challenges persist pancreatic ductal adenocarcinoma (PDAC) treatment. Particularly, there is a critical issue of inadequate intratumoral infiltration effector T cells, primarily attributed to the physical “hard” barrier caused by extracellular matrix (ECM) and “soft” imposed immune suppression. Here, dual‐warhead nanomedicine reported that effectively targets attacks barriers precisely sensitize PDAC immunotherapy. The achieved designing tumor cell membrane vesicle (TMV)‐coated polyamidoamine dendrimer‐condensed siRNA complexes, with hedgehog inhibitor encapsulated TMV bilayers. With precision‐guided stealth feature coating, powerful tumor‐targeting co‐delivery siRNA, resulting decrease collagen I secretion efficient silencing target gene disrupt ECM suppression barriers. This enables robust immunity against progression metastasis, offering potent approach therapy.

Abstract Gastrointestinal cancers, a major global cause of cancer‐related mortality and disease burden, are heterogeneous group malignant aliments involving different organs the digestive system. The late clinical diagnosis, genomic tumor heterogeneity, high complexity gastrointestinal microenvironment, along with increasing treatment resistance have been recognized as main contributing factors to current inadequacy interventions poor prognosis cancer patients. In coming years, is unfortunately predicted increase due absence early detection effective therapeutic options. Biomembrane‐coated biomimetic nanoparticles (NPs) recently appointed advanced nanotechnological tools for management cancers. These comprise not only cell‐mimicking nanodevices (the pioneers this top‐down coating technology), but also exosome bacterial mimetics. Due their enhanced bio‐interfacing features, biocompatibility, immune evasion, specific targetability tumorous tissues, these nanostructures successfully exploited provide safer, effective, targeted applications. This review highlights latest research on biomembrane‐coated nanosystems therapy diagnosis most common deadliest subtypes namely colorectal cancer, gastric liver esophageal pancreatic cancer. challenges toward translation mentioned.

In pancreatic ductal adenocarcinoma (PDAC), stromal cells and matrix proteins form a dense physical barrier that, while preventing the outward spread of tumor cells, also limits penetration drugs CD8+ T inward. Additionally, overactivated TGF-β/SMAD signaling pathway further promotes proliferation immune suppression. Therefore, crossing preserving integrity stroma, releasing intratumorally, remodeling activating system is promising drug delivery strategy. this work, type enamine N-oxides modified nanoparticle was prepared, with stearic acid-modified gemcitabine prodrug (GemC18) pSMAD2/3 inhibitor galunisertib encapsulated. The peripheral can trigger transcytosis then respond to hypoxia acidic microenvironments, turning surface charge nanoparticles positive enhancing penetration. released inhibits pathway, reshapes matrix, activates antitumor immunity, combines (Gem) kill cells.

Pancreatic cancer remains one of the most challenging malignancies to treat due its dense stromal microenvironment and resistance conventional therapies. This study introduces a novel localized drug delivery system design target residual cells following surgery. Electrospun fibrous carriers were fabricated using needle-less electrospinning from polycaprolactone (PCL), silk fibroin (SF), their blend. Among these, PCL (average fiber diameter: 141 ± 28 nm) exhibited highest sustained paclitaxel (PTX) release in vitro. Coating carrier with hyaluronic acid (HA) increased diameter 535 116 nm modulated PTX release, shifting an initial rapid phase uncoated more gradual over 120 hours. PTX-loaded HA-coated electrospun significantly reduced MiaPaCa cell viability, only 13% viability at 96 hours compared 22% for non-coated carrier. offers scalable efficient solution delivery, providing prolonged cytotoxic efficacy, off-target effects. Its industrial scaleability, combined potential post-surgical pancreatic management, presents innovative approach minimizing reliance on systemic chemotherapy associated toxicities. The use Nanospider TM technology further emphasizes clinical potential, future vivo studies needed confirm carrier’s safety, pharmacokinetics, therapeutic benefits.
