Bombesin receptor subtype-3 (BRS-3) is an orphan G protein-coupled receptor having sequence homologies to gastrin-releasing peptide and neuromedin B receptors. [d-Phe6, beta-Ala11, Phe13, Nle14]bombesin(6-14) is known to act as a synthetic receptor agonist for BRS-3. To characterize BRS-3-mediated biological responses, we examined the effect of BRS-3 activation by [d-Phe6, beta-Ala11, Phe13, Nle14]Bn(6-14) on the adhesion of the small cell lung cancer NCI-N417 cells that express native BRS-3. We found that the BRS-3 agonist stimulated adhesion of NCI-N417 cells in laminin-coated culture wells. The adhesion of the cells to laminin induced by BRS-3 activation was accompanied by an increase in vinculin-like immunoreactivity and diminished in the presence of an anti-beta1 integrin antibody, suggesting that the receptor activation stimulates focal adhesion formation. We suggest that BRS-3 may be involved in invasion and metastasis of certain cancer cells, like small cell lung cancer cells, upon attachment to laminin.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

Introduction: Immunotherapy targeting PD-1/PD-L1 shows significant benefits in lung cancer. Cutaneous immune-related adverse events (irAEs) are frequent, early-developing side effects of ICIs, and their potential role as prognostic markers in non-small cell lung cancer (NSCLC) therapy requires further exploration.
Methods: Data of patients with NSCLC treated with camrelizumab Combined with chemotherapy were collected at Xuzhou Medical University from 2019 to 2023.

Purpose: (Tumor-educated platelets) TEPs have emerged as active players in all steps of tumorigenesis, confrontation of platelets with tumor cells via transfer of tumor-associated biomolecules and results in the sequestration of such biomolecules. The current study was aimed to examine whether TEPs lncRNA-STARD4-AS1 and ELOA-AS1 might be potential biomarkers for NSCLC.
Materials And Methods: TEPs were obtained by low-speed centrifugation.

While NUSAP1's association with various tumors is established, its predictive value for prognosis and immunotherapy in lung adenocarcinoma (LUAD) remains unconfirmed. We analyzed Nucleolar Spindle-Associated Protein 1 (NUSAP1) gene expression in TCGA and GTEx datasets and validated it in clinicopathological tissues using qRT-PCR and immunohistochemistry. Additionally, we investigated NUSAP1's relationship with patient prognosis across TCGA and five GEO cohorts.
