Article Abstract
Background: Lung cancer stands as one of the most prevalent malignancies globally, with its high morbidity and mortality intimately associated with its inconspicuous early symptoms, the advanced stages at diagnosis, and resistance to conventional therapeutic interventions. Exosomes, serving as pivotal mediators of intercellular communication, carry biomolecules that play crucial roles in tumorigenesis, progression, and metastasis, holding promise as novel targets for early diagnosis, prognostic evaluation, and treatment of lung cancer.
Methods: In this study, lung cancer-related datasets were obtained from the GEO database and TCGA. Through differential gene analysis, enrichment analysis, immune infiltration analysis, and drug regulatory analysis, exosome-associated genes pertinent to lung cancer were screened and identified.
Results: The research revealed significant downregulation of CRYAB, CAV1, HYAL1, and TUBB6 genes in lung cancer tissues, whereas SERINC2, PAICS, SLC2A1, and BIRC5 genes were markedly upregulated. These genes were predominantly enriched in biological processes such as cell migration, oxidative stress response, and cell cycle regulation, as well as in KEGG pathways like the IL-17 signaling pathway. Immune infiltration analysis demonstrated a high correlation between these genes and the infiltration levels of various immune cells. Furthermore, through drug-gene enrichment analysis and molecular docking experiments, significant correlations were found between drugs such as celecoxib and some exosome-related genes, with interaction targets existing between these drugs and CAV1, SLC2A1, and BIRC5 genes.
Conclusion: This study unveils the expression characteristics and biological significance of exosome-associated genes in lung cancer. The differential expression of these genes not only offers potential biomarkers for early diagnosis of lung cancer but also lays a foundation for further research into their biological functions in this disease.

A Mg(OTf)-catalyzed asymmetric Michael addition/cyclization cascade reaction between 3-isothiocyanato oxindoles and 2-arylidene-1,3-indanediones has been developed. This transformation provides an efficient and concise approach to biologically important bispiro[indanedione-oxindole-pyrrolidinyl]s under mild conditions in good to excellent yields (70-99% yields) with moderate to good stereoselectivities (up to 99% and >95:5 d.r.

Introduction: Immunosenescence remodels immune functions and was first described with aging. It is present in 25% of cancer patients but has also been described in patients with Immune-mediated inflammatory diseases (IMIDs). This study aims at quantifying cells exhibiting a phenotype of senescence in CD4+ (T4sen) and CD8+ (T8sen) T cells, analyzing its potential drivers and the effect of anti-TNF treatment in a prospective cohort of patients with rheumatoid arthritis (RA), spondyloarthritis (SpA) and Sjögren disease (SjD).

Objectives: Bladder cancer is a common malignancy with high incidence and poor prognosis. N-methyladenosine (mA) modification is widely involved in diverse physiological processes, among which the mA recognition protein YTH N-methyladenosine RNA binding protein F2 (YTHDF2) plays a crucial role in bladder cancer progression. This study aims to elucidate the molecular mechanism by which O-linked -acetylglucosamine (O-GlcNAc) modification of YTHDF2 regulates its downstream target, period circadian regulator 1 (), thereby promoting bladder cancer cell proliferation.

Objectives: Non-small cell lung cancer (NSCLC) is associated with poor prognosis, with 30% of patients diagnosed at an advanced stage. Mutations in the and genes are important prognostic factors for NSCLC, and targeted therapies can significantly improve survival in these patients. Although tissue biopsy remains the gold standard for detecting gene mutations, it has limitations, including invasiveness, sampling errors due to tumor heterogeneity, and poor reproducibility.

Aims: We aimed to analyze CD63, a cell surface protein that has been associated with tumor aggressiveness in several cancers, including breast, colorectal, and lung cancer, as well as melanoma, in prostate cancer.
Methods: CD63 expression was analyzed immunohistochemically in a cohort of primary prostate cancers from 281 patients. The results were correlated with clinico-pathologic parameters, including biochemical recurrence.
