Globally, lung adenocarcinoma (LUAD) remains the leading cause of cancer‑related mortality, highlighting the urgent need for innovative therapeutic approaches. Necroptosis has been recognized as a crucial mechanism for inhibiting cancer progression. Research has revealed a significant association between microRNA (miRNA)‑mediated necroptosis and tumor progression. The present study aimed to elucidate the role and underlying mechanisms of miR‑10b‑5p in regulating necroptosis in the context of LUAD. In an investigation of LUAD, miRNA sequencing was conducted on both LUAD and adjacent non‑tumor tissues, followed by the integration of external database information to identify specific target miRNAs. The expression of miR‑10b‑5p was verified in LUAD tissues and corresponding adjacent non‑cancerous tissues using immunohistochemistry. In vitro experiments, utilizing LUAD cell lines engineered to modulate miR‑10b‑5p levels, assessed its effects on cellular activities and necroptosis. The inhibition of PKP3 by miR‑10b‑5p was determined using a dual luciferase reporter system. Furthermore, alterations in miR‑10b‑5p levels were found to affect PKP3 expression and inhibit the RIPK3/MLKL signaling pathway, as evidenced by western blot analysis in LUAD cell lines. The effect of PKP3 knockdown on cell activity and necroptosis in LUAD cell lines with low miR‑10b‑5p expression levels was assessed using cell function assays. Finally, a nude mouse xenograft model was used to investigate the effect of miR‑10b‑5p on LUAD growth in vivo and its specific mechanism of action. It has been revealed that miR‑10b‑5p levels are significantly elevated in LUAD specimens. Further investigations demonstrated that an increase in miR‑10b‑5p enhances the proliferation of LUAD cells and suppresses the progression of necroptosis, as evidenced by in vitro experiments. Through dual luciferase reporter assays, PKP3 was confirmed as a direct target negatively regulated by miR‑10b‑5p, leading to reduced expression levels. Western blot analysis indicated that miR‑10b‑5p inhibits the RIPK3/MLKL pathway activation through downregulation of PKP3, which leads to increased cell proliferation and decreased necroptosis. However, knockdown of PKP3 reversed the inhibitory effect of miR‑10b‑5p inhibitors on cellular activity and inhibited necrosis by suppressing the RIPK3/MLKL signalling pathway. In addition, animal model studies demonstrated that inhibition of miR‑10b‑5p activated the RIPK3/MLKL pathway by promoting PKP3 expression and significantly reduced LUAD growth by promoting necroptosis. In conclusion, our studies have revealed that the miR‑10b‑5p functions as a tumorigenic factor, enhancing various cellular activities in LUAD cells and suppressing necroptosis by specifically targeting PKP3, thereby inhibiting activation of the RIPK3/MLKL pathway. Importantly, interventions using inhibitors that specifically target miR‑10b‑5p have shown significant success in impeding the progression of LUAD by promoting necroptosis in both cellular and animal models. Thus, targeting miR‑10b‑5p holds considerable potential as a therapeutic strategy for LUAD.

Ring finger protein 125 (RNF125), a ubiquitin E3 ligase, has been reported to act as a tumor suppressor in several cancers, but its precise function in lung adenocarcinoma (LUAD) has not been elucidated. In the present study, through bioinformatics analysis and immunohistochemistry in LUAD and non‑cancerous samples, it was demonstrated that RNF125 was significantly downregulated in lung cancer. Low levels of RNF125 expression were associated with metastatic status, advanced tumor stage and poor overall survival in LUAD. The results of gain‑ and loss‑of‑function experiments demonstrated that RNF125 inhibited proliferation, colony formation, migration and invasion of LUAD cells. In addition, RNF125 increased the sensitivity of LUAD cells to cisplatin. Mechanistically, RNF125 interacted with programmed cell death ligand 1 (PD‑L1) and reduced PD‑L1 expression levels in LUAD cells. Furthermore, IL‑2 secretion by Jurkat T cells was significantly suppressed when co‑cultured with RNF125‑silenced LUAD cells. NK‑92 cell lysis of RNF125‑silenced LUAD cells was also weaker compared with that of control LUAD cells, suggesting that RNF125 knockdown enhanced the immune evasion ability of LUAD cells. Notably, the results of the present study identified that the RNA‑binding protein muscleblind‑like 1 (MBNL1) is the upstream regulator of RNF125 in LUAD. MBNL1 increased the stability of the RNF125 transcript in LUAD cells and knockdown of RNF125 reversed the antitumor effect of MBNL1 on LUAD cells. In conclusion, the present study demonstrated the tumor suppressor role of RNF125 in LUAD and implicated MBNL1 as an upstream regulator of RNF125 in LUAD. These findings contributed to an improved understanding of the molecular features of LUAD progression.

We report a new usage of folic acid-modified dendrimer-entrapped gold nanoparticles (Au DENPs-FA) as nanoprobes for in vitro and in vivo targeted computed tomography (CT) imaging of human lung adencarcinoma. In this study, Au DENPs prepared using amine-terminated generation 5 poly(amidoamine) dendrimers as templates were covalently linked with FA, followed by an acetylation reaction to neutralize the remaining dendrimer surface amines. The formed Au DENPs-FA was used for both in vitro and in vivo targeted CT imaging of human lung adencarcinoma cells (SPC-A1 cells) and the xenograft tumor model, which express folic acid receptors (FAR) verified by immunohistochemical staining. Micro-CT images show that SPC-A1 cells can be detected under X-ray after incubation with the Au DENPs-FA in vitro and the xenograft tumor model can be imaged after intravenous, intratumoral, and intraperitoneal administration of the particles. Transmission electron microscopy data confirm that the Au DENPs-FA is able to be uptaken dominantly in the lysosomes of the cells. Combined morphological observation of cells after Hematoxylin and Eosin staining, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay of cell viability , and flow cytometric analysis of cell cycle and apoptosis show that the Au DENPs-FA does not affect cell morphology , viability, and cell cycle and apoptosis, indicating their good biocompatibility at the given concentration range. These findings suggest that the developed Au DENPs-FA have a great potential to be used as imaging probes for targeted CT imaging of human lung adencarcinoma.

Background Computed tomography (CT) is widely used all over the world, and the detection rate of early lung adenocarcinoma is increasing. Minimally invasive thoracic surgery (MITS) has emerged as the preferred surgical approach for lung adenocarcinoma, but identifying small lung adenocarcinomas is difficult. Therefore, there is a need for a non-invasive, convenient and efficient way to localize lung adenocarcinomas.Materials and Methods A targeted gold nanocluster for intraoperative fluorescence imaging by intratracheal delivery has been designed. Au-GSH-anti Napsin A nanoclusters (NapA-AuNCs) were synthesized, and their physicochemical properties and optical properties were characterized. Target effect, cytotoxicity and fluorescence time curve of NapA-AuNCs, were tested in vivo and in vitro, and intratracheal delivery was also carried.Results NapA-AuNCs targeting lung adenocarcinoma with red fluorescence and good mucus penetration were synthesized, which had the targeting property of A549 and lung adenocarcinoma tissue, and also had very low toxicity to normal lung epithelial cells and organs. Intracheal delivery involves faster imaging of lung adenocarcinoma and less accumulation of other organs than intravenous administration.Conclusion NapA-AuNCs targeting lung adenocarcinoma were successfully conjugated, and intratracheal delivery is a safe, effective for lung adenocarcinoma intraoperative localization.

Background Lung adenocarcinoma (LUAD) patients are implicated in poor prognoses and increased mortality rates. Metastasis, as a leading cause of LUAD-related deaths, requires further investigation. Highly metastatic cancer cells often exhibit extensive characteristics of epithelial-mesenchymal transition (EMT). This study attempted to identify novel targets associated with LUAD metastasis and validate their specific molecular mechanisms. Methods Bioinformatics was conducted to determine NTSR1 expression in LUAD and the enriched pathways. Immunohistochemical analysis was used to assess NTSR1 expression in LUAD tissue. qRT-PCR examined expressions of NTSR1 and Wnt/β-Catenin pathway-related genes in LUAD cells. Transwell assayed cell migration and invasion. Cell adhesion experiments were conducted to evaluate cell adhesion capacity. Western blot analysis was employed to examine expression of EMT, Wnt/β-Catenin pathway, and cell adhesion markers. Results NTSR1 was upregulated in LUAD tissues and cells, and enriched in EMT pathway. Knockdown of NTSR1 reduced migration, invasion, and adhesion abilities in LUAD cells, and inhibited EMT progression and Wnt/β-Catenin pathway. Rescue experiments demonstrated that β-Catenin activator SKL2001 reversed repressive influence of NTSR1 knockdown on LUAD cell malignant phenotypes and EMT progression. Conclusion The data obtained in this study suggested that NTSR1 stimulated EMT and metastasis in LUAD via Wnt/β-Catenin pathway. This finding may provide options for overcoming LUAD metastasis.

Lung adenocarcinoma (LAC) is a common lung cancer with a high malignancy that urgently needs to be treated with effective drugs. Ginsenoside Rh4 exhibits outstanding antitumor activities. However, few studies reported its effects on growth, metastasis and molecular mechanisms in LAC. Here, Rh4 is certified to show a strong anti-LAC efficiency in vitro and in vivo. Results of flow cytometry and Western blot are obtained to exhibited that Rh4 markedly restrained cellular proliferation and colony formation by arresting the cell cycle in the G1 phase. Results from a wound healing assay and transwell assays demonstrated that Rh4 is active in the antimigration and anti-invasion of LAC. The analysis of Western blot, immunofluorescence and RT-qPCR confirmed that Rh4 reverses the epithelial–mesenchymal transition (EMT) through upregulating the gene expression of E-cadherin and downregulating that of snail, N-cadherin and vimentin. In vivo results from immunohistochemistry show consistent trends with cellular studies. Furthermore, Rh4 suppresses the Janus kinases2/signal transducer and activator of the transcription3 (JAK2/STAT3) signaling pathway stimulated by TGF-β1. Silencing the STAT3 signal or co-treating with AG490 both enhanced the EMT attenuation caused by Rh4, which revealed that Rh4 suppressed EMT via inhibiting the JAK2/STAT3 signaling pathway. These findings explore the capacity and mechanism of Rh4 on the antimetastasis of LAC, providing evidence for Rh4 to LAC therapy.Keywords:ginsenoside Rh4;lung adenocarcinoma;metastasis;cell cycle;JAK/STAT signaling

Current understanding of micropapillary (MP)-subtype lung adenocarcinoma (LUAD) remains confined to biological activities and genomic landscapes. Unraveling the major regulatory programs underlying MP patterned malignancy offers opportunities to identify more feasible therapeutic targets for patients with MP LUAD. This study shows that patients with MP subtype LUAD have aberrant activation of the MYC pathway compared to patients with other subtypes. In vitro and xenograft mouse model studies reveal that MP pattern in malignancy cannot be solely due to aberrant MYC expression but requires the involvement of M2-like macrophages. Excessively expressed MYC leads to the accumulation of M2-like macrophages from the bone marrow, which secretes TGFβ, to induce the expression of FOSL2 in tumor cells, thereby remodeling chromatin accessibility at promoter regions of MP-pattern genes to promote the MYC-mediated de novo transcriptional regulation of these genes. Additionally, the MP-pattern in malignancy can be effectively alleviated by disrupting the TGFβ-FOSL2 axis. These findings reveal new functions for the M2-like macrophage-TGFβ-FOSL2 axis in MYC-overexpressing MP-subtype LUAD, identifying targetable vulnerabilities in this pathway.

Background Lung adenocarcinoma (LUAD) is a non-small cell carcinoma. Ribonuclease/angiogenin inhibitor 1 (RNH1) exerts multiple roles in virous cancers. E2F1 is a critical transcription factor involved in the LUAD development. Here, we analyze the expression of RNH1 in LUAD patients, investigate the biological function of RNH1 in LUAD, and demonstrate its potential mechanisms through E2F1 in LUAD. Methods In the present study, we presented the expression of RNH1 in LUAD based on the database and confirmed it by western blot detection of RNH1 in human LUAD tissues. Lentiviral infection was constructed to silence or overexpress RNH1 in NCI-H1395 and NCI-H1437 cells. We assess the role of RNH1 on proliferation in LUAD cells by MTT assay, colony formation assays, and cell cycle detection. Hoechst staining and flow cytometry were used to evaluate the effects of RNH1 on apoptosis of LUAD cells. The function of RNH1 in invasion and migration was investigated by Transwell assay. Dual luciferase assay, ChIP detection, and pull-down assay were conducted to explore the association of E2F1 in the maintenance of RNH1 expression and function. The regulation of E2F1 on the functions of RNH1 in LUAD cells was explored. Mouse experiments were performed to confirm the in-vivo role of RNH1 in LUAD. mRNA sequencing indicated that RNH1 overexpression altered the expression profile of LUAD cells. Results RNH1 expression in LUAD tissues of patients was presented in this work. Importantly, RNH1 knockdown improved the proliferation, migration and invasion abilities of cells and RNH1 overexpression produced the opposite effects. Dual luciferase assay proved that E2F1 bound to the RNH1 promoter (-1064 ∼ -1054, -1514 ∼ -1504) to reduce the transcriptional activity of RNH1. ChIP assay indicated that E2F1 DNA was enriched at the RNH1 promoter (-1148 ∼ -943, -1628 ∼ -1423). Pull-down assays also showed the association between E2F1 and RNH1 promoter (-1148 ∼ -943). E2F1 overexpression contributed to the malignant behavior of LUAD cells, while RNH1 overexpression reversed it. High-throughput sequencing showed that RNH1 overexpression induced multiple genes expression changes, thereby modulating LUAD-related processes. Conclusion Our study demonstrates that binding of E2F1 to the RNH1 promoter may lead to inhibition of RNH1 expression and thus promoting the development of LUAD.

Background Lung adenocarcinoma (LUAD) is known to be one of the leading causes of cancer-related deaths globally. In recent decades, long non-coding RNAs (lncRNAs) have been indicated to exert pivotal regulating functions in multiple biological behaviors in the initiation and development of LUAD. However, the functional mechanism of lncRNA GATA binding protein 6 antisense RNA 1 (GATA6-AS1) in LUAD has not been explored. Methods In the current study, GATA6-AS1 expression in LUAD tissues was revealed. Meanwhile, GATA6-AS1 expression in LUAD cells was investigated via RT-qPCR analysis. After A549 and H1975 cells were transfected with GATA6-AS1 overexpression plasmids, EdU and colony formation assays, TUNEL assays and flow cytometry analyses, as well as wound healing and Transwell assays were conducted to detect cell proliferation, apoptosis, migration and invasion. Afterwards, bioinformatic tools, western blot analyses, dual-luciferase reporter assays, and RNA immunoprecipitation (RIP) assays were performed to investigate the correlation of microRNA-4530 (miR-4530), GATA6-AS1 and GATA6. Results We found that GATA6-AS1 expression was low-expressed in LUAD tissues and cells. Furthermore, the upregulation of GATA6-AS1 suppressed the proliferative, migration and invasion abilities, as well as promoted apoptotic rate of A549 and H1975 cells. Moreover, the mechanistic investigations revealed that GATA6-AS1 upregulated the expression of its cognate sense gene GATA6 by binding with miR-4530, thereby modulating the malignant progression of LUAD cells. Conclusions GATA6-AS1 repressed LUAD cell proliferation, migration and invasion, and promoted cell apoptosis via regulation of the miR-4530/GATA6 axis, indicating GATA6-AS1 as a new prognostic biomarker for LUAD.

MicroRNA (miR)-140-3p has been proved to repress lung adenocarcinoma (LUAD), and our study aims to further evaluate the mechanism. Bioinformatic analyses were performed. The viability, proliferation, migration, invasion and angiogenesis of transfected LUAD cells were all determined via Cell Counting Kit-8, colony formation, Scratch, Transwell, and tube formation assays. The targeting relationship between miR-140-3p and thymidylate synthetase (TYMS) was confirmed by dual-luciferase reporter assay. Relative expressions of miR-140-3p, TYMS, epithelial-to-mesenchymal transition- (E-cadherin, N-cadherin, vimentin), angiogenesis- (vascular endothelial growth factor (VEGF)), and apoptosis-related factors (cleaved caspase-3, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax)) were quantified by quantitative real-time polymerase chain reaction or Western blot. TYMS was high-expressed yet miR-140-3p was low-expressed in LUAD cells. Upregulation of miR-140-3p inhibited TYMS expression, viability, colony formation, migration, invasion, and tube length within LUAD cells, while downregulation of miR-140-3p did oppositely. Silenced TYMS, the downstream target gene of miR-140-3p, reversed the effects of miR-140-3p downregulation on TYMS expression, cell viability, colony formation, migration, invasion, and tube length as well as the metastasis-, apoptosis- and angiogenesis-related proteins in LUAD cells. Upregulation of miR-140-3p inhibited the proliferation, migration, invasion and angiogenesis of LUAD cells via targeting TYMS.

Palmitoylation is a post-translational modification occurring on cysteine residues, which process is catalyzed by a family of zinc finger Asp-His-His-Cys (DHHC) domain-containing (ZDHHC) protein acyltransferases. As a family member, ZDHHC9 plays a crucial role in varied malignancies by regulating protein stability via protein substrate palmitoylation. Based on the bioinformatic analysis of GEO gene microarray GSE75037 (|log 2 fold change|> 1, P < 0.05), ZDHHC9 was defined as a significantly upregulated gene in lung adenocarcinoma (LUAD), which was also confirmed in our collected clinical specimens. It is necessary to explore the biological function of ZDHHC9 in LUAD cells. The follow-up functional experiments revealed that ZDHHC9 deficiency inhibited proliferation, migration, and invasion, while stimulated apoptosis in HCC827 cells. Besides, these malignant phenotypes could be accelerated by ZDHHC9 overexpression in A549. Moreover, we revealed that ZDHHC9 knockdown could promote PD-L1 protein degradation by reducing its palmitoylation level. The reduction of PD-L1 protein level could enhance anti-tumor immunity and inhibit the growth of LUAD cells. Therefore, our study uncovers the tumor-promoting role of ZDHHC9 in LUAD via regulating PD-L1 stability through palmitoylation, highlighting ZDHHC9 as a novel therapeutic target for LUAD.

Indolent lung cancer is characterized by slow progression, and the patient may die of other causes before it becomes symptomatic. The increasing usage of lung cancer screening technologies has increased the detection of early-stage cancers, improved survival, and reduced mortality, but it also brings overdiagnosis or overtreatment for indolent lung cancer patients. In this study, we performed high-throughput whole-exome sequencing in lung adenocarcinoma (LUAD) patients with a tumor doubling time of more than 600 days (the indolent group) and another group with a tumor doubling time of less than 30 days (the aggressive group). We identified a novel germline variation in PDZRN4 , rs74955204 (p.G121E, c.362 G > A) in the indolent group. The rs74955204 variant resulted in upregulated PDZRN4 expression and was positively correlated with the survival of LUAD patients. We confirmed that overexpression of PDZRN4 inhibits the ubiquitylation of HIF-1A mediated by TRIM28, thus activating HIF-1A-IGFBP3 signaling to promote apoptosis, and inducing NDRG1 to inhibit EGFR-AKT signaling, restricting lung cancer cell growth in vitro and in vivo. With the EGFR L858R -driven lung cancer mouse model as an example, we found that PDZRN4 knockout promoted, whereas PDZRN4 overexpression suppressed LUAD growth in vivo. In addition, recombinant PDZRN4 or screened small molecules retinoic acid showed potent inhibitory effects on EGFR-driven LUAD growth and amelioration of osimertinib resistance. Overall, our findings suggest that targeted PDZRN4 is a potential therapeutic strategy for treating LUAD. Examination of PDZRN4 rs74955204 variant may be an effective approach for the early detection of indolent lung cancer and to avoid overdiagnosis. Graphical : Germline variation rs74955204 (p.G121E, c.362 G > A) in PDZRN4 significantly upregulated PDZRN4 expression and resulted in indolent growth of LUAD. Overexpressed PDZRN4 inhibits the ubiquitylation of HIF-1A by TRIM28, activating HIF-1A-IGFBP3 signaling to promote apoptosis, and inducing NDRG1 to inhibit EGFR-AKT signaling, thus restricting lung cancer cell growth.
