Metabolic Intervention Liposome Boosted Lung Cancer Radio‐Immunotherapy via Hypoxia Amelioration and PD‐L1 Restraint

Advanced Science, Год журнала: 2023, Номер 10(18)

At present, radiotherapy (RT) still acquires limited success in clinical due to the lessened DNA damage under hypoxia and acquired immune tolerance owing amplified programmed death ligand-1 (PD-L1) expression. Incredibly, intracellular PD-L1 expression depression is proven better sensitize RT by inhibiting repair. However, disability of clinically used antibodies disrupting extracellular PD-L1function limits effectiveness radio-immunotherapy. Therefore, regulation strategies are urgently needed Hence, for this purpose, TPP-LND synthesized linking mitochondrial-targeted triphenylphosphine cations (TPP+ ) antineoplastic agent lonidamine (LND), which significantly reduces dose LND induce effective oxidative phosphorylation inhibition (2 vs 300 µM). Then, wrapped with liposomes form TPP-LND@Lip nanoparticles. By doing this, nanoparticles can reversing hypoxic microenvironment tumors generate more reducing via enhancing adenosine 5'-monophosphate-activated protein kinase activation. As expected, these well-designed economical than conventional anti-PD-L1 some extent.

Lung cancer is the leading cause of cancer-related mortality for males and females. Radiation therapy (RT) one primary treatment modalities lung cancer. While delivering prescribed dose to tumor targets, it essential spare tissues near targets—the so-called organs-at-risk (OARs). An optimal RT planning benefits from accurate segmentation gross volume surrounding OARs. Manual a time-consuming tedious task radiation oncologists. Therefore, crucial develop automatic image relieve oncologists contouring work. Currently, atlas-based technique commonly used in clinical routines. However, this depends heavily on similarity between atlas segmented. With significant advances made computer vision, deep learning as part artificial intelligence attracts increasing attention medical segmentation. In article, we reviewed based techniques related compared them with technique. At present, auto-segmentation OARs relatively large such heart etc. outperforms organs small esophagus. The average Dice coefficient (DSC) lung, liver are over 0.9, best DSC spinal cord reaches 0.9. esophagus ranges 0.71 0.87 ragged performance. terms volume, below 0.8. Although indicate superiority many aspects manual segmentation, various issues still need be solved. We discussed potential including low contrast, dataset size, consensus guidelines, network design.

Dasatinib-related resistance frequently occurs and may lead to the failure of chemotherapy; thus, dose interruptions are necessary. Cannabidiol (CBD) has potential for integration with orthodox cancer care. In this study, we explored combination effect CBD dasatinib on A549 cells. in could induce significant synergistic apoptosis vitro (ZIP > 10) vivo. The low-dose exhibited antiproliferative proapoptotic effects through up-regulation caspase-3 Bax, down-regulation Bcl-2 xenograft mouse model suggested that was more efficient safer. short, a anticancer by targeting SRC/PI3K/AKT signaling pathway, suggesting therapeutic option treatment lung cancer.

Radiotherapy (RT) is a major treatment method for non-small-cell lung cancer (NSCLC), and development of new modality now critical to amplify the negative effects RT on tumors. In this study, we demonstrated nanoparticle-loaded block copolymer micellar system hyperthermia (HT) that can be used synergistic therapy under alternating magnetic field (AMF) radiation field. Block micelles (polyethylene glycol-block-polycaprolactone, or PEG-PCL) containing hyaluronic acid (HA) Mn–Zn ferrite nanoparticles (MZF) were fabricated via two-step preparation. HA-modified (MZF-HA) enriched in CD44 highly expressing tumor cells, such as A549 (human adenocarcinoma cell line), through an active targeting mechanism receptor–ligand binding HA (HA receptor). MZF generate thermal energy AMF, leading local temperature increase approximately 43 °C at sites mild HT, increased oxygenation enhance therapeutic effect RT. vitro experiments show MZF-HA able achieve excellent specific performance toward cells with biocompatibility well enhanced HT by apoptosis flow cytometry. subcutaneous xenografts model, MRI confirms enrichment tumor, hypoxia immunohistochemistry analysis (IHC) proved after HT.

Up-regulation of VANGL1 by IGF2BPs and miR-29b-3p attenuates the detrimental effect of irradiation on lung adenocarcinoma

Journal of Experimental & Clinical Cancer Research, Год журнала: 2020, Номер 39(1)

Опубликована: Ноя. 23, 2020

Abstract Accumulating evidence suggests that radiation treatment causes an adaptive response of lung adenocarcinoma (LUAD), which in turn attenuates the lethal effect irradiation. Previous microarray assays manifested change gene expression profile after Bioinformatics analysis significantly changed genes revealed VANGL1 may notably influence on LUAD. To determine role VANGL1, this study knocked down or overexpressed M6A level mRNA was determined by M6A-IP-qPCR assay. Irradiation caused up-regulation with increase m6A level. Depletion readers, IGF2BP2/3, undermined stability and upon miR-29b-3p decreased irradiation, however is a target identified Luciferase report The reduction inhibited degradation mRNA. Knockdown enhanced detrimental irradiation LUAD, as indicated more severe DNA damage increased percentage apoptotic cells. Immunocoprecipitation interaction between BRAF. BRAF probably through suppressing protein degradation, led to downstream effectors, TP53BP1 RAD51. These effectors are involved repair damage. In summary, which, turn, mitigated LUAD protecting from activating BRAF/TP53BP1/RAD51 cascades. Increased reduced took responsibility overexpression

Critical Reviews in Oncology/Hematology, Год журнала: 2024, Номер 196, С. 104284 - 104284

Опубликована: Фев. 2, 2024

Non-small cell lung cancer (NSCLC) remains one of the leading causes cancer-related deaths worldwide. Different treatment approaches are typically employed based on stage NSCLC. Common clinical methods include surgical resection, drug therapy, and radiation therapy. However, with introduction utilization immune checkpoint inhibitors, has entered a new era, completely revolutionizing landscape for various cancers significantly improving overall patient survival. Concurrently, resistance often poses critical challenge, many patients experiencing disease progression following an initial response due to resistance. Increasing evidence suggests that tumor microenvironment (TME) plays pivotal role in Tumor-associated macrophages (TAMs) within TME can promote NSCLC by secreting cytokines activating signaling pathways, interacting other cells. Therefore, this article will focus elucidating key mechanisms TAMs analyze how targeting reduce levels NSCLC, providing comprehensive understanding principles overcome
