Background

The monotherapeutic efficacy of immune checkpoint inhibitors (ICIs) remains unsatisfactory in patients suffering from non-small-cell lung cancer (NSCLC). Ferroptosis, an iron-dependent cell death process, has been identified as a promising immunotherapy adjuvant; however, ferroptosis inducers (such as erastin, RSL3) may paradoxically up-regulate hypoxia-inducible factor 1α (HIF-1α) and programmed death ligand 1 (PD-L1) to propel tumor immune evasion. It is critical to explore the molecular mechanism of ferroptosis in NSCLC immunotherapy and verify the efficacy of combined regimens for overcoming ICI limitations clinically.

Methods

This work analyzed 162 NSCLC patients receiving immunotherapy retrospectively to evaluate correlation between PD-L1 expression and progression-free survival (PFS). In vitro, CCK-8 assay, flow cytometry, qPCR, and Western blotting were utilized to measure impacts of ferroptosis inducers (Erastin, RSL3) upon cell viability, reactive oxygen species (ROS) levels, and PD-L1/HIF-1α expression in A549/H1299 NSCLC cells; ferroptosis-specific effects were validated by means of iron chelators (DFO, ferrostatin-1). In vivo, subcutaneous tumor models were built in C57BL/6 mice with LLC cells; therapeutic effects of ferroptosis inducer (IKE) alone or combined with anti-PD-1 antibody were evaluated through tumor weight measurement and immunohistochemistry (IHC). HIF-1α binding to PD-L1 promoter was confirmed via chromatin immunoprecipitation (ChIP); related signaling pathways were explored using transcriptome sequencing and KEGG enrichment analysis.

Results

For NSCLC patients who received immunotherapy, high PD-L1 expression correlated with longer PFS, and 4-HNE was associated positively with PD-L1 and CD8⁺T infiltration. In vitro, Erastin/RSL3 induced dose-dependent cell death, ROS accumulation, and PD-L1 up-regulation, reversed by iron chelators. In vivo, IKE+anti-PD-1 inhibited tumor growth significantly, whereas it increased CD8⁺T infiltration. Mechanistically, Erastin up-regulated HIF-1α via PI3K-AKT, which bound PD-L1 promoter (ChIP-verified), reversed by iron chelators.

Conclusions

Ferroptosis inducers have dual effects in NSCLC, namely, promoting tumor cell death and triggering PD-L1-dependent immune evasion via the PI3K-AKT-HIF-1α pathway. However, combining ferroptosis inducers with anti-PD-1 antibodies retains the anti-tumor effect of ferroptosis and overcomes immune evasion by obstructing the PD-L1 pathway, offering a novel strategy for enhancing NSCLC immunotherapy efficacy.
背景:免疫检查点抑制剂(ICIs)单药治疗非小细胞肺癌(NSCLC)的疗效仍不理想。铁下垂是一种铁依赖性细胞死亡过程,已被确定为一种有前途的免疫治疗辅助剂;然而,铁ptosis诱导剂(如erastin, RSL3)可能矛盾地上调缺氧诱导因子1α (HIF-1α)和程序性死亡配体1 (PD-L1),以促进肿瘤免疫逃避。在非小细胞肺癌免疫治疗中,探讨铁下垂的分子机制,验证联合治疗方案对克服ICI局限性的临床疗效至关重要。方法:回顾性分析162例接受免疫治疗的非小细胞肺癌患者,评价PD-L1表达与无进展生存期(PFS)的相关性。在体外,采用CCK-8法、流式细胞术、qPCR和Western blotting检测铁凋亡诱导剂(Erastin、RSL3)对A549/H1299 NSCLC细胞活力、活性氧(ROS)水平和PD-L1/HIF-1α表达的影响;通过铁螯合剂(DFO,铁抑素-1)验证了铁致死特异性效应。在体内,用LLC细胞建立C57BL/6小鼠皮下肿瘤模型;通过测量肿瘤重量和免疫组化(IHC)评价铁下垂诱导剂(IKE)单独或联合抗pd -1抗体的治疗效果。通过染色质免疫沉淀(ChIP)证实HIF-1α与PD-L1启动子结合;通过转录组测序和KEGG富集分析探索相关信号通路。结果:在接受免疫治疗的NSCLC患者中,PD-L1高表达与PFS延长相关,4-HNE与PD-L1和CD8 + T浸润呈正相关。在体外,Erastin/RSL3诱导剂量依赖性细胞死亡、ROS积累和PD-L1上调,而铁螯合剂可逆转这一现象。在体内,IKE+抗pd -1明显抑制肿瘤生长,而CD8 + T的浸润增加。在机制上,Erastin通过PI3K-AKT上调HIF-1α, PI3K-AKT结合PD-L1启动子(chip验证),被铁螯合剂逆转。结论:铁凋亡诱导剂在NSCLC中具有双重作用,即通过PI3K-AKT-HIF-1α途径促进肿瘤细胞死亡和触发pd - l1依赖性免疫逃避。然而,将铁ptosis诱导剂与抗pd -1抗体联合使用,可以保留铁ptosis的抗肿瘤作用,并通过阻断PD-L1途径克服免疫逃避,为提高NSCLC免疫治疗效果提供了一种新的策略。

In the landscape of acute myeloid leukemia (AML) research, mutations in nucleophosmin 1 (NPM1) are the most prevalent genetic alterations. The leukemogenic mutant variant, NPM1c⁺, is associated with a distinct gene expression profile linked to leukemia, but the downstream oncogenic pathways remain only partially understood. Long non-coding RNAs (lncRNAs) are RNA molecules with known regulatory roles in human development and disease. Research implicates many lncRNAs in hematopoiesis and leukemogenesis, revealing correlations between their expression and clinical parameters in AML patients. While NPM1c⁺ AML exhibits a distinct lncRNA signature, it remains contentious whether these molecules are bona fide drivers or passenger events, and how their context-dependent functions can be therapeutically exploited.
This review focuses on lncRNAs in NPM1c⁺ AML, highlighting their roles in pathogenesis, prognosis, and chemoresistance. By systematically elucidating the role of lncRNAs as pivotal factors in the diagnosis, treatment, and prognosis of NPM1c⁺ AML, this study addresses a gap in the existing literature. Our analysis of specific lncRNAs, such as HOTAIRM1, HOXB-AS3, CRNDE, HOXBLINC, LONA, IFEX9, XLOC_109948, and HOTTIP, enhances our understanding of the molecular mechanisms underlying AML in the context of NPM1c⁺. These findings lay the groundwork for developing targeted therapies and improved prognostic tools for NPM1c⁺AML.
在急性髓性白血病(AML)的研究中,核磷蛋白1 (NPM1)的突变是最普遍的遗传改变。导致白血病的突变体NPM1c⁺与一种与白血病相关的独特基因表达谱有关,但下游的致癌途径仍只被部分了解。长链非编码RNA (lncRNAs)是已知在人类发育和疾病中具有调节作用的RNA分子。研究发现许多lncrna参与造血和白血病发生,揭示了它们在AML患者中的表达与临床参数之间的相关性。虽然NPM1c + AML显示出独特的lncRNA特征,但这些分子是真正的驱动者还是乘客事件,以及如何利用它们的环境依赖功能进行治疗,仍然存在争议。本文综述了NPM1c + AML中的lncrna,重点介绍了它们在发病机制、预后和化疗耐药中的作用。通过系统阐明lncRNAs在NPM1c + AML的诊断、治疗和预后中的关键作用,本研究弥补了现有文献的空白。我们对特定lncrna(如HOTAIRM1、HOXB-AS3、CRNDE、HOXBLINC、LONA、IFEX9、XLOC_109948和HOTTIP)的分析增强了我们对NPM1c⁺在AML中的分子机制的理解。这些发现为开发针对NPM1c + AML的靶向治疗和改进的预后工具奠定了基础。

Background

Cancer-associated fibroblasts (CAFs) play a key role in prostate cancer (PCa) progression, though their heterogeneity and specific protumorigenic subsets remain poorly characterized. This study aimed to identify and validate a distinct THY1⁺ CAF subset associated with aggressive PCa.

Methods

Multiomics data from public (TCGA-PRAD, GEO) and prospective (FUSCC, n = 84) cohorts were analyzed. An 8-gene CAF-derived prognostic signature was constructed using LASSO Cox regression. THY1⁺ CAF clusters were identified via scRNA-seq. Primary CAFs were isolated from patient tissues, and THY1⁺/THY1⁻ subpopulations were purified via MACS/FACS. Angiogenic function and secretory profiles were assessed through tube formation assays, ELISA, and antibody arrays. THY1 knockdown and CXCR2 inhibition were used for mechanistic studies. Clinical relevance was evaluated via qPCR and multiplex immunohistochemistry on tissue microarrays.

Results

High CAF abundance correlated with aggressive clinicopathological features and poor prognosis in PCa. The 8-gene signature effectively predicted biochemical recurrence (BCR). scRNA-seq revealed THY1⁺ CAFs as a proangiogenic subpopulation. THY1⁺ CAFs enhanced angiogenesis via increased secretion of CXCL6 and VEGFA. CXCL6 promoted endothelial tube formation through CXCR2 activation, while THY1 knockdown downregulated VEGFA and impaired angiogenesis. High THY1⁺ CAF infiltration was associated with significantly worse recurrence-free survival.

Conclusion

THY1⁺ CAFs represent a proangiogenic subset that drives PCa progression via the CXCL6/CXCR2 axis and THY1-mediated VEGFA expression. These findings highlight stromal THY1 and the CXCL6/CXCR2 pathway as potential therapeutic targets.
背景:癌症相关成纤维细胞(CAFs)在前列腺癌(PCa)的进展中起着关键作用,尽管它们的异质性和特定的蛋白发生亚群仍然缺乏特征。这项研究旨在鉴定和验证与侵袭性PCa相关的THY1 + CAF亚群。方法:对来自公共队列(TCGA-PRAD, GEO)和前瞻性队列(FUSCC, n = 84)的多组学数据进行分析。使用LASSO - Cox回归构建8基因caf衍生的预后特征。通过scRNA-seq鉴定THY1 + CAF簇。从患者组织中分离出原代CAFs,通过MACS/FACS纯化THY1⁺/THY1⁻亚群。血管生成功能和分泌谱通过管形成试验、ELISA和抗体阵列进行评估。THY1敲除和CXCR2抑制用于机制研究。通过组织微阵列上的qPCR和多重免疫组化来评估临床相关性。结果:高CAF丰度与前列腺癌侵袭性临床病理特征和不良预后相关。8基因标记可有效预测生化复发(BCR)。scRNA-seq显示THY1 + CAFs是促血管生成亚群。THY1 + CAFs通过增加CXCL6和VEGFA的分泌增强血管生成。CXCL6通过激活CXCR2促进内皮管的形成,而THY1敲低则下调VEGFA并损害血管生成。高THY1 + CAF浸润与明显较差的无复发生存率相关。结论:THY1 + CAFs代表一个促血管生成亚群,通过CXCL6/CXCR2轴和THY1介导的VEGFA表达驱动PCa进展。这些发现强调基质THY1和CXCL6/CXCR2通路是潜在的治疗靶点。

Background

Early diagnosis of pancreatic cancer (PC) remains challenging, particularly in patients with chronic pancreatitis (CP). Currently, imaging is often inaccurate and biopsy is inherently invasive. This is the first network meta-analysis (NMA) comparing blood-based biomarkers for differentiating PC from CP.

Methods

PubMed and EMBASE were searched for studies evaluating blood-based biomarkers for distinguishing PC from CP. Risk of bias was assessed with QUADAS-2. We conducted individual biomarker meta-analysis with generalized bivariate models. For the NMA, we applied a Bayesian inference approach via a Markov-chain Monte Carlo random effects model. The surface under the cumulative ranking curve was used to rank the diagnostic performance of the biomarkers.

Results

Across 139 enrolled studies, 49 biomarkers or panels were analyzed. For differentiating PC from CP, tumor polypeptide antigen (TPA) had the highest area under the summary receiver operating characteristic curve (AUSROC) (0.92). The NMA revealed that microRNA-196b (miR-196b) ranked highest in sensitivity (OR 3.74e+27), while the combination of carbohydrate antigen 19–9 (CA199) and a panel of eight extracellular vesicle long RNAs (exLRs) exhibited the highest specificity (OR 3.78). For early-stage (stage I and II) PC, the eight exLRs showed the highest relative sensitivity (OR 7.00), and carcinoembryonic antigen (CEA) demonstrated the highest specificity (OR 4.70).

Conclusion

CA199 demonstrated only moderate diagnostic discrimination between PC and CP, with reduced efficacy in early-stage PC. Combining CA199 and eight exLRs exhibited promising differential diagnostic efficacy with both high sensitivity and specificity.
背景胰腺癌(PC)的诊断仍然具有挑战性,特别是慢性胰腺炎(CP)患者。目前,成像通常是不准确的,活检本身就是侵入性的。方法检索spubmed和EMBASE中评估血液生物标志物区分PC和CP的研究,并使用QUADAS-2评估偏倚风险。我们使用广义双变量模型进行了个体生物标志物荟萃分析。对于NMA,我们通过马尔可夫链蒙特卡洛随机效应模型应用贝叶斯推理方法。累积排序曲线下的曲面用于对生物标志物的诊断性能进行排序。结果在139项入组研究中,分析了49种生物标志物或组。在鉴别PC与CP时,肿瘤多肽抗原(tumor polypeptide antigen, TPA)在总接受者工作特征曲线(AUSROC)下的面积最高(0.92)。NMA显示,microRNA-196b (miR-196b)的敏感性最高(OR 3.74e+27),而碳水化合物抗原19-9 (CA199)和一组8个细胞外囊泡长rna (exlr)的组合具有最高的特异性(OR 3.78)。对于早期(I期和II期)PC, 8个exlr的相对敏感性最高(OR 7.00),癌胚抗原(CEA)的特异性最高(OR 4.70)。结论ca199对PC和CP的诊断鉴别能力较弱,对早期PC的鉴别能力较弱。CA199联合8种exLRs具有较高的敏感性和特异性,具有良好的鉴别诊断效果。

NF-κB activation as a pro-survival signal from pharmacological inhibition of pyruvate dehydrogenase kinase 1 in non-small-cell lung carcinoma cell models 非小细胞肺癌细胞模型中丙酮酸脱氢酶激酶1的药理抑制可激活NF-κB作为促生存信号

Targeting Pyruvate dehydrogenase kinase (PDK) has emerged as one of the potential therapeutic strategies for non-small cell lung carcinoma (NSCLC). 64, a recently reported PDK1 inhibitor derived from 2,2-dichloroacetophenone (DAP), exhibited promising anticancer effects in NSCLC models. Herein, we sought to investigate the mechanism of action of 64 in two NSCLC cell lines, namely, NCI-H1975 and NCI-H1650. We found that 64 induced intrinsic cancer cell apoptosis by releasing cytochrome C (CytC) from mitochondria, leading to caspase-3 and poly (ADP-ribose) polymerase (PARP) cleavage, which was mediated by reactive oxygen species (ROS). Moreover, we have shown that 64 induced mitochondrial membrane potential (MMP) depolarization and AMPK/MAPK activations were also ROS driven. With the aid of sequencing studies and follow-up biochemical evaluations, we found that 64 activated the NF-κB pathway through P38 MAPK, while the combination of P38 MAPK inhibitor SB203580 with 64 diminished such activation. Interestingly, the combined use of 64 and NF-κB inhibitor (JSH-23) increased pro-apoptosis protein (Bax) expression and decreased pro-survival protein (Bcl-2) expression, resulting in enhanced cancer cell apoptosis via JNK pathway. Our results suggested that 64 induces cancer cell apoptosis in NSCLC models through ROS, while NF-κB activation serves as a survival mechanism upon PDK1 inhibition.
靶向丙酮酸脱氢酶激酶(PDK)已成为非小细胞肺癌(NSCLC)的潜在治疗策略之一。64是最近报道的PDK1抑制剂,从2,2-二氯苯乙酮(DAP)中提取,在NSCLC模型中显示出有希望的抗癌作用。在此,我们试图研究64在NCI-H1975和NCI-H1650两种非小细胞肺癌细胞系中的作用机制。我们发现64通过从线粒体释放细胞色素C (CytC),导致caspase-3和聚(adp -核糖)聚合酶(PARP)裂解,从而诱导内在癌细胞凋亡,这一过程由活性氧(ROS)介导。此外,我们已经证明64诱导的线粒体膜电位(MMP)去极化和AMPK/MAPK激活也是ROS驱动的。通过测序研究和后续的生化评价,我们发现64通过P38 MAPK激活NF-κB通路,而P38 MAPK抑制剂SB203580与64的联合抑制了这种激活。有趣的是,64和NF-κB抑制剂(JSH-23)联合使用增加了促凋亡蛋白(Bax)的表达,降低了促生存蛋白(Bcl-2)的表达,从而通过JNK途径增强了癌细胞的凋亡。我们的研究结果表明64通过ROS诱导NSCLC模型的癌细胞凋亡,而NF-κB激活是PDK1抑制后的生存机制。

TLN1, a cytoskeletal protein associated with various tumors, remains inadequately studied in gliomas. In this study, we examined the functional role and mechanisms of TLN1 in glioma pathogenesis. Utilizing public databases, we conducted differential expression, survival (Kaplan-Meier/ROC), and regression analyses, which were subsequently validated with institutional datasets and clinical tissues. In vitro experiments demonstrated that TLN1 knockdown in glioma cells resulted in reduced proliferation (CCK8/EDU), migration and invasion (wound healing/Transwell), and increased apoptosis (AO/EB/flow cytometry); these findings were corroborated by Western blot analyses. Gene Set Enrichment Analysis (GSEA) linked TLN1 to the TGF-beta signaling pathway, a connection further validated by Western blot and in vivo murine models. Both public and institutional data indicated that TLN1 was upregulated in gliomas, with elevated expression correlating with poor prognosis. Furthermore, TLN1 knockdown inhibited glioma growth and progression in vitro and in vivo, primarily through the TGF-beta signaling pathway. Our findings establish TLN1 as an oncogenic driver in gliomas and highlight its potential as a therapeutic target.

Phosphoglucomutase 5 suppresses gallbladder cancer progression by inhibiting lactate-driven STAT3 signaling 磷酸葡萄糖糖化酶5通过抑制乳酸驱动的STAT3信号传导抑制胆囊癌的进展

Gallbladder cancer (GBC) is a highly aggressive malignancy of the biliary tract with limited therapeutic options. Phosphoglucomutase 5 (PGM5), a key enzyme in glucose metabolism, has been implicated as a tumor suppressor in several cancers, yet its role and mechanism in GBC remain unclear. Here, we demonstrate that PGM5 is significantly downregulated in GBC tissues, and its low expression correlates with poor prognosis. Using integrated bioinformatic analysis, we found that PGM5 loss is associated with enhanced glycolysis and activation of the STAT3 signaling pathway. Functionally, PGM5 overexpression significantly inhibited GBC cell proliferation, migration, and invasion, and promoted apoptosis, whereas PGM5 knockdown exerted the opposite effects. Mechanistically, PGM5 suppressed lactate production by downregulating lactate dehydrogenase A (LDHA), leading to decreased phosphorylation of STAT3. The anti-tumor effects of PGM5 were reversed by exogenous lactate supplementation, and the glycolytic inhibitor 2-DG abrogated the oncogenic phenotypes induced by PGM5 silencing. In a mouse xenograft model, PGM5 overexpression significantly restrained tumor growth, reduced LDHA and p-STAT3 levels, and decreased intratumoral lactate content. Our findings reveal that PGM5 acts as a tumor suppressor in GBC through disruption of the lactate-STAT3 signaling axis, highlighting its potential as a therapeutic target for metabolic intervention in GBC.
胆囊癌(GBC)是一种高度侵袭性的胆道恶性肿瘤,治疗选择有限。磷酸葡萄糖糖糖化酶5 (PGM5)是葡萄糖代谢的关键酶,在几种癌症中被认为是肿瘤抑制因子,但其在GBC中的作用和机制尚不清楚。本研究表明PGM5在GBC组织中显著下调,其低表达与预后不良相关。通过综合生物信息学分析,我们发现PGM5缺失与糖酵解增强和STAT3信号通路的激活有关。功能上,PGM5过表达显著抑制GBC细胞增殖、迁移和侵袭,促进细胞凋亡,而PGM5敲低则相反。机制上,PGM5通过下调乳酸脱氢酶A (LDHA)抑制乳酸生成,导致STAT3磷酸化降低。外源性乳酸补充可逆转PGM5的抗肿瘤作用,糖酵解抑制剂2-DG可消除PGM5沉默诱导的致癌表型。在小鼠异种移植瘤模型中,PGM5过表达显著抑制肿瘤生长,降低LDHA和p-STAT3水平,降低瘤内乳酸含量。我们的研究结果表明,PGM5通过破坏乳酸- stat3信号轴在GBC中发挥肿瘤抑制作用,突出了其作为GBC代谢干预治疗靶点的潜力。

IF 5 2区 医学 Q2 Medicine Pub Date : 2026-03-01 Epub Date: 2026-01-23 DOI: 10.1016/j.tranon.2026.102665

Objective

Cancer-associated fibroblasts (CAFs) are a critical component of the tumor microenvironment and play a significant role in renal cell carcinoma (RCC) progression and treatment response. However, current methods for evaluating CAFs infiltration in RCC are inadequate. This study aims to develop a non-invasive histopathological model based on H&E staining and collagen features to predict CAFs infiltration and investigate its prognostic value and biological relevance.

Methods

We conducted a retrospective analysis using H&E pathological images and clinical data from The Cancer Genome Atlas (TCGA) database. A Pathomics model integrating 465 histopathological features was constructed using machine learning algorithms (n = 354) to predict CAFs infiltration. A preliminary technical validation was performed using multiphoton microscopy-based collagen quantification (n = 25) to assess the correlation between the Pathomics Score and CAF-related fibrotic activity. Enrichment analysis, immune cell infiltration profiling, and mutation analysis were employed to explore the biological mechanisms underlying the model.

Results

The Pathomics model demonstrated high predictive accuracy (AUC=0.813) and correlated significantly with collagen deposition (r = 0.66, P < 0.001). High Pathomics scores were independently associated with poor survival (HR=1.80, P = 0.003) and linked to key biological processes, including YAP/TAZ activation, extracellular matrix (ECM) remodeling, immune suppression (e.g., CD276, IDO1), and frequent mutations in VHL and PBRM1 (>40%).

Conclusion

This study establishes the first H&E-based Pathomics framework for quantifying CAFs infiltration in RCC, providing a cost-effective and non-invasive tool for preliminary risk stratification. The model’s strong correlation with collagen features and its ability to reveal underlying molecular mechanisms highlight its potential for potential value in understanding the stromal microenvironment, though further external validation is required for clinical translation.

Lung cancer has an extremely high mortality rate among malignant tumors, posing a significant threat to human health Among all lung cancer cases, non-small cell lung cancer (NSCLC) accounts for a significant proportion and has become a hot topic in clinical research and treatment. The Kirsten rat sarcoma viral oncogene homolog (KRAS) is one of the most common oncogenic drivers in NSCLC, closely associated with tumor initiation, treatment response, and prognosis. However, due to the relatively smooth surface of the KRAS protein and the lack of drug-binding pockets, it has long been regarded as an "undrugable target". With further research, recently, targeted drugs targeting the KRASG12C gene mutation have achieved significant breakthroughs in clinical trials, especially the application of KRASG12C-specific inhibitors adagrasib and sotorasib, which has changed the treatment landscape for NSCLC patients. To address challenges such as tumor heterogeneity, the complexity of the tumor microenvironment, interpatient variability, and acquired drug resistance mechanisms, combination therapy strategies involving KRASG12C inhibitors have emerged sequentially. This article systematically reviews the progress of targeted therapy for KRASG12C-mutant NSCLC and the results of related clinical trials, while exploring novel therapeutic strategies for patients with KRASG12C mutations, aiming to provide a reference for the selection of clinical treatment regimens.
肺癌是恶性肿瘤中死亡率极高的肿瘤,对人类健康构成重大威胁。在所有肺癌病例中,非小细胞肺癌(non-small cell Lung cancer, NSCLC)占了相当大的比例,已成为临床研究和治疗的热点。Kirsten大鼠肉瘤病毒癌基因同源物(KRAS)是NSCLC中最常见的致癌驱动因子之一,与肿瘤起始、治疗反应和预后密切相关。然而,由于KRAS蛋白表面相对光滑,缺乏药物结合口袋,长期以来被认为是“不可磨灭的靶标”。随着研究的深入,近年来,针对KRASG12C基因突变的靶向药物在临床试验中取得了重大突破,尤其是KRASG12C特异性抑制剂阿达格拉西和索托拉西的应用,改变了NSCLC患者的治疗格局。为了应对诸如肿瘤异质性、肿瘤微环境复杂性、患者间变异性和获得性耐药机制等挑战,涉及KRASG12C抑制剂的联合治疗策略相继出现。本文系统综述KRASG12C突变型NSCLC靶向治疗进展及相关临床试验结果,同时探索KRASG12C突变患者的新治疗策略,旨在为临床治疗方案的选择提供参考。

Background

Lung adenocarcinoma (LUAD) remains a major clinical challenge in assessment of clinical outcomes and therapeutic response. Although tumor-associated macrophages (TAMs) are known as crucial regulators of tumor progression, their heterogeneity and prognostic relevance in LUAD have not been fully elucidated.

Methods

The heterogeneity of TAMs was detected by integration analyses of single-cell data and spatial transcriptome data. The CTSB+ TAM-related signature (CTRS) was developed by machine learning algorithms across four LUAD datasets. Multi-omics analysis and functional experiments were applied to uncover the potential role and mechanism of CTSB+ TAMs in LUAD.

Results

Single-cell analysis identified CTSB⁺ TAM as a crucial player in LUAD progression with poor prognosis. The spatial co-localization of CTSB⁺ TAMs and tumor cells was confirmed on LUAD slides. Our proposed CTRS was generated and validated in four independent LUAD cohorts, with high scores indicating unfavorable outcomes Furthermore, high CTRS scores were correlated with immunosuppressive status, and poor responses to immune checkpoint blockade. Functional experiments demonstrated the role of CTSB+ TAMs in boosting proliferation and migration in LUAD cells.

Conclusion

Our research develops CTRS with reliable performance in evaluating patient clinical outcomes in LUAD, highlighting its potential utility in clinical decision-making.
背景肺腺癌(LUAD)仍然是评估临床结果和治疗反应的主要临床挑战。尽管肿瘤相关巨噬细胞(tam)被认为是肿瘤进展的关键调节因子,但它们在LUAD中的异质性和预后相关性尚未完全阐明。方法通过对单细胞数据和空间转录组数据的整合分析,检测tam的异质性。CTSB+ tam相关签名(CTRS)是通过跨四个LUAD数据集的机器学习算法开发的。通过多组学分析和功能实验,揭示了CTSB+ tam在LUAD中的潜在作用和机制。结果单细胞分析发现CTSB + TAM在预后不良的LUAD进展中起关键作用。LUAD玻片证实了CTSB + tam与肿瘤细胞的空间共定位。我们提出的CTRS在四个独立的LUAD队列中生成并验证,得分高表明结果不利。此外,高CTRS得分与免疫抑制状态和免疫检查点封锁反应差相关。功能实验证实了CTSB+ tam在LUAD细胞中促进增殖和迁移的作用。结论本研究开发的CTRS在评估LUAD患者临床结果方面具有可靠的性能,突出了其在临床决策中的潜在应用价值。

Functional experiments demonstrated the role of CTSB<sup>+</sup> TAMs in boosting proliferation and migration in LUAD cells.</div></div><div><h3>Conclusion</h3><div>Our research develops CTRS with reliable performance in evaluating patient clinical outcomes in LUAD, highlighting its potential utility in clinical decision-making.</div></div>","PeriodicalId":48975,"journal":{"name":"Translational Oncology","volume":"65 ","pages":"Article 102671"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145947978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
