Moreover, the integration of genetic and molecular analyses has facilitated the identification of novel therapeutic targets. For instance, the study of alternative polyadenylation (APA) has revealed its significant role in the regulation of gene expression in NSCLC, with implications for understanding cancer susceptibility and progression (ref: Jin doi.org/10.1002/advs.202502008/). The characterization of extracellular vesicles and their associated biomarkers has also emerged as a promising avenue for improving diagnostic accuracy and therapeutic monitoring in SCLC (ref: Li doi.org/10.1002/advs.202416711/). Collectively, these findings underscore the complexity of SCLC biology and the necessity for continued research into its molecular mechanisms to enhance patient outcomes.
