- Programmed cell death (PCD) encompasses multiple regulated processes whose dysregulation shapes cancer fitness, yet current computational studies largely use known PCD genes for prognosis rather than discovering regulators. We developed xNNPCD, an interpretable neural-network framework that links CRISPR-Cas9 perturbation signatures from CMap to gene dependency profiles from DepMap. The model constrains hidden neurons to five PCD pathways and iteratively refines a prior gene-pathway mask matrix derived from GO, KEGG, and Reactome using pathway-neuron ablation. This converts binary gene-pathway relationships into continuous-valued associations and improves dependency prediction over random forests, standard fully connected multi-layer perceptron, and its own non-iterative variant. The learned matrix recovers annotated death regulators and nominates candidate regulators, including , and ; combined with dependency scores, it further separates pathway coupling from regulatory direction. Transferring the refined relationship matrix and learned weights to compound-induced perturbation data enables drug screening, identifying BRD-K19103580 and decitabine as targeted therapeutic agents for apoptosis and ferroptosis, respectively. The pathway-resolved drug profiles can facilitate the rational design of combination therapies targeting complementary PCD pathways to overcome single-pathway resistance. Overall, xNNPCD offers a generalizable, interpretable approach for mapping the regulatory landscape and elucidating the molecular processes of PCD in cancer. - Source: PubMed

Yin QingyangChen Liang - Acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is a major challenge in the treatment of lung adenocarcinoma (LUAD). Our previous study demonstrated that EGFR signaling activates calcium/calmodulin-dependent protein kinase 2 (CAMK2). However, the relationship between this mechanism and TKI resistance has not been fully elucidated. - Source: PubMed

The mechanism through which Cr(VI) exposure causes lung cancer remains to be clearly defined. No effective strategies are currently available to prevent lung cancer resulting from chronic Cr(VI) exposure. Kava is traditionally consumed by South Pacific Islanders to reduce anxiety. Epidemiology and experimental studies suggest that kava has anticancer potential and may be used as a preventive agent to reduce the risk of various cancers including lung cancer. The purpose of this study is to determine the effect of AB-Free Kava and its active component dihydromethysticin (DHM) on chronic Cr(VI) exposure-induced cell malignant transformation and the underlying mechanism. The study was performed by pretreating immortalized but nontumorigenic human bronchial epithelial cells (BEAS-2B) with AB-Free Kava (25 μg/mL) or DHM (10 μM) followed by exposing cells to 0.25 μM Cr(VI) (KCrO) for 20 weeks to determine the impact of AB-Free Kava or DHM on chronic Cr(VI) exposure-induced cell transformation, cancer stem cell (CSC)-like properties, and tumorigenesis. The extent of cell transformation was evaluated by soft agar colony formation assays, Western blot analysis of cancer stemness marker expression levels, and nude mouse xenograft tumorigenesis assays. It was found that AB-Free Kava or DHM pretreatment significantly reduces Cr(VI)-induced cell transformation, CSC-like properties, and tumorigenesis. Mechanistically, it was determined that AB-Free Kava or DHM impairs Cr(VI)-induced cell transformation by down-regulating RNA splicing factor small nuclear ribonucleoprotein polypeptide A' (SNRPA1) expression to reduce the protooncogene, cancer stemness marker, and driver c-MYC expression. It was further determined that DHM and SNRPA1 regulate c-MYC expression through affecting c-MYC protein stability. It was concluded that AB-Free Kava or DHM inhibits Cr(VI)-induced cell transformation, CSC-like properties, and tumorigenesis by down-regulating RNA splicing factor SNRPA1 expression to increase the protooncogene c-MYC protein degradation. - Source: PubMed

Bie BeibeiLiu LibingWang FurongMeng XianingWu MengdiSun Jin - Non-small cell lung cancer (NSCLC) is a major cause of cancer-related deaths worldwide. One protein involved in RNA processing and splicing, SNRPA1, has been suggested to play a role in the pathogenesis of NSCLC. Therefore, investigating the regulatory mechanisms involving small nuclear ribonucleoprotein polypeptide A' (SNRPA1) in NSCLC could provide valuable insights into the disease progression. The study involved the analysis of SNRPA1, methyltransferase 3, n6-adenosine-methyltransferase complex catalytic subunit (METTL3), insulin like growth factor 2 mRNA binding protein 2 (IGF2BP2) and twist family bHLH transcription factor 1 (TWIST1) expressions in lung tissues and normal lung tissues using data obtained from the TCGA, CPTAC, and/or ENCORI databases. The prognostic value of SNRPA1 in lung tissues was assessed through the Kaplan-Meier Plotter database and TCGA database. mRNA expression was quantified via qRT-PCR, while protein expression was evaluated using western blotting assay or IHC assay. Cell viability, proliferation, migration, and invasion were analyzed through various in vitro assays. The interaction between SNRPA1 and METTL3 or IGF2BP2 was studied using RIP assay, dual-luciferase reporter assay, and actinomycin D assay, while the association of SNRPA1 with TWIST was determined through Co-IP assay and CHX assay. The effects of METTL3 silencing and SNRPA1 overexpression on malignant growth of NSCLC cells were confirmed using a xenograft mouse model assay and a lung metastasis model. SNRPA1 expression was significantly upregulated in NSCLC tissues and cells. Depletion of SNRPA1 led to the inhibition of NSCLC cell proliferation, migration, and invasion. Additionally, METTL3 and IGF2BP2 were found to stabilize SNRPA1 mRNA expression through m6A methylation modification. SNRPA1 overexpression attenuated the effects induced by METTL3 knockdown on NSCLC cells in vitro. Furthermore, SNRPA1 was observed to interact with TWIST1 in NSCLC cells, and TWIST1 overexpression attenuated SNRPA1 knockdown-induced effects on the key malignant phenotypes. In vivo experiments showed that SNRPA1 overexpression rescued the effects of METTL3 depletion on the malignant growth of NSCLC cells. The findings of this study highlight the crucial role of the METTL3/IGF2BP2-SNRPA1-TWIST1 axis in promoting NSCLC development through m6A methylation modification. Targeting this pathway may offer novel therapeutic strategies for the treatment of NSCLC. - Source: PubMed
