Background: has been popularly consumed since ancient times as a traditional medicine in China to treat whooping cough, bronchial asthma, and febrile convulsive twitch disease. This led us to investigate whether extract (BSE) may be effective against lung cancer, especially non-small cell lung carcinoma (NSCLC).
Methods: In this study, we extracted the ethanolic root extract of the grass, . study, the change of NCI-H1299 cell proliferation was observed with CCK8 and MTT assays. Cell apoptosis was assessed using a kit based on staining with FITC-conjugated annexin V. study, we establish a stable animal model of NSCLC in nude mice, tumor volume and weight was measured twice a week. We conduct gene microarray screened for differentially expressed genes (DEGs), between NCI-H1299 cells treated by BSE or not. Then the DEGs were functionally annotated and path enriched.
Results: It was revealed that BSE significantly suppressed NSCLC cell proliferation (IC 134 μg/mL) and induced apoptosis. It also slowed tumor growth without affecting body weight, and a dose of 25 g/kg led to significantly smaller tumors than in control animals (13.85±3.36 23.40±6.05, P=0.044). Apoptosis-related protein direct IAP Binding protein with low PI (DIABLO) expression was up-regulated by BSE, and DIABLO knockdown significantly attenuated the anti-tumor effects of the extract.
Conclusions: In conclusion, BSE reduces the viability of NSCLC cells and promotes apoptosis, and these effects may be mediated by DIABLO.

Pseudouridine (Ψ) is a post-transcriptional modifier of RNA, often referred to as the 'fifth nucleotide' owing to its regulatory role in various biological functions as well as because of its significant involvement in the pathogenesis of human cancer. In recent years, research has revealed various Ψ modifications in different RNA types, including messenger RNA, transfer RNA, ribosomal RNA, small nuclear RNA, and long noncoding RNA. Pseudouridylation can significantly alter RNA structure and thermodynamic stability, as the Ψ-adenine (A) base pair is more stable than the typical uridine (U)-A base pair is due to its structural similarity to adenine.

Introduction: Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy by enhancing the antitumor immune response. This case describes an 80-year-old male with synchronous multiple primary malignancies (MPMs), including lung metastatic hepatocellular carcinoma (HCC), and non-small cell lung carcinoma (NSCLC), and brain metastatic urothelial carcinoma, who was treated with dual ICI therapy.
Case Presentation: The patient, with a history of diabetes, hypertension, dyslipidaemia, well-differentiated neuroendocrine duodenal tumors and micronodular exogenous cirrhosis (Child-Pugh class A), presented with a non-invasive bladder carcinoma (pT1N0M0) resected endoscopically in December 2022.

Objective: Epithelial-mesenchymal transition (EMT) and metastasis are the primary causes of mortality in non-small-cell lung cancer (NSCLC). 5'-3' exoribonuclease 2 (XRN2) plays an important role in the process of tumor EMT. Thus, this investigation mainly aimed to clarify the precise molecular pathways through which XRN2 contributes to EMT and metastasis in NSCLC.
