Small cell lung cancer (SCLC) is a high-grade neuroendocrine tumor characterized by initial sensitivity to chemotherapy, followed the development of drug resistance. The underlying mechanisms resistance in SCLC have not been fully elucidated. Aldo-keto reductase family 1 member C3 (AKR1C3), known be associated with chemoradiotherapy diverse tumors. We aim evaluate prognostic significance and immune characteristics AKR1C3 investigate its potential role promoting SCLC.

Cancer cell proliferation requires precise control of E2F1 activity; excess activity promotes apoptosis. Here, we developed cell-permeable and bioavailable macrocycles that selectively kill small lung cancer (SCLC) cells with inherent high by blocking RxL-mediated interactions cyclin A B select substrates. Genome-wide CRISPR/Cas9 knockout random mutagenesis screens found A/B RxL macrocyclic inhibitors (cyclin A/Bi) induced apoptosis paradoxically B- Cdk2-dependent spindle assembly checkpoint activation (SAC). Mechanistically, A/Bi hyperactivate their RxL-interactions Myt1, respectively, ultimately leading to SAC mitotic death. Base editor identified variants confer resistance including several disrupted B:Cdk interactions. Unexpectedly but consistent our base screens, the formation neo-morphic Cdk2-cyclin complexes promote Finally, orally-bioavailable robustly inhibited tumor growth in chemotherapy-resistant patient-derived xenograft models SCLC. This work uncovers gain-of-function mechanisms which induce cancers E2F activity, suggests as a therapeutic strategy for SCLC other driven activity.

Abstract Small cell lung cancer (SCLC) is a recalcitrant characterized by early metastasis, rapid tumor growth and poor prognosis. In recent decades, the epidemiology, initiation mutation characteristics of SCLC, as well abnormal signaling pathways contributing to its progression, have been widely studied. Despite extensive investigation, fewer drugs approved for SCLC. Recent advancements in multi-omics studies revealed diverse classifications SCLC that are featured distinct therapeutic vulnerabilities. With accumulation samples, different subtypes specific treatments these were further explored. The identification molecular has opened up novel avenues treatment SCLC; however, inconsistent uncertain classification hindered translation from basic research clinical applications. Therefore, comprehensives review essential conclude emerging related targeting vulnerabilities within pathways. this current review, we summarized risk factors, classification, We hope will facilitate subtyping theory application.

Histologic transformation from EGFR-mutant non-small cell lung cancer (NSCLC) to small-cell (SCLC) is a key mechanism of resistance EGFR tyrosine kinase inhibitors (TKI). However, transcriptomic changes between NSCLC and transformed SCLC (t-SCLC) remain unexplored.
