After an initial response, most patients become resistant, and compensatory mechanisms are not fully uncovered [<span>3</span>]. To address this, we analyzed HR<sup>+</sup> resistant CAMA1 and 747D cells using whole-exome and RNA sequencing, supplemented by proteomics and target validation with human samples.

CAMA1 and T47D cells, treated with palbociclib and fulvestrant (PF) for 2 years, developed resistance (CAMA1-PFR and T47D-PFR) confirmed by proliferation assays and elevated half-maximal inhibitory concentrations.

This was supported by elevated reactive oxygen species (ROS) levels in PF-treated parental cells (Figure 1D).

The guidelines of the European Association of Urology (EAU) suggest a 6-weekly induction phase followed by a maintenance schedule of BCG once weekly for 3 weeks and at 3, 6, 12, 18, 24, 30, and 36 months for 1 to 3 years [<span>2</span>].

Hence, a better understanding of the molecular mechanisms underlying oral cancer metastasis and the identification of therapeutic vulnerabilities are needed to prevent and treat metastatic disease.&lt;/p&gt;&lt;p&gt;We collected 87 primary tumors and 21 lymph node metastasis (LNM) from 72 OSCC patients to conduct comprehensive transcriptome-wide expression and correlation analyses (Figure 1A). First, we performed expression-based clustering with all primary tumors and observed the best subdivision with &lt;i&gt;k&lt;/i&gt; = 3 using protein-coding and non-coding genes (Figure 1B). Of note, we observed transcriptional heterogeneity among multiregional tumor samples in about 30% of the cases, leading to the assignment of these patients and their respective tumors to different clusters. Intriguingly, Kaplan-Meier analysis of patients whose tumors were unambiguously assigned to only one cluster revealed that cluster 3 (C3) had the worst outcome, with a median survival of 15.6 months compared to 28.57 and 36.53 months for clusters 1 (C1) and 2 (C2), respectively (Figure 1C). Importantly, prognostic factors known to negatively affect survival, such as high T, N, and G status, were not enriched in C3 tumors (Supplementary Figure S1A-C). However, gene expression analysis identified 244 genes that were significantly changed in C3 compared to C1/2 tumors (Supplementary Figure S1D, Supplementary Table S1).

Thus, we further tested their prognostic relevance for OS and recurrence/disease-free survival (RFS/DFS) in our patient cohort (Figure 1E, Supplementary Figure S2A-C) as well as in The Cancer Genome Atlas (TCGA) HNSCC dataset (Supplementary Figure S2D-E) [&lt;span&gt;4&lt;/span&gt;].

Both drugs offer promising options for individualized treatment targeting HER2 and HER3 expression, potentially even in tumors which are currently considered “HER2-negative”. Relatively little is known about the efficacy of HER3-DXd in tumors with low HER3 expression, except for data from one recent study investigating its efficacy across different HER3 expression levels [&lt;span&gt;3&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;The DESTINY-Breast04 trial (NCT03734029) demonstrated that T-DXd-treated patients with HER2-low expressing metastatic breast cancer had significantly longer progression-free and overall survival than those who were treated with the physician's choice of chemotherapy [&lt;span&gt;4&lt;/span&gt;]. It is therefore important to understand whether neoadjuvant systemic therapy is able to induce or up-regulate HER2 and/or HER3 protein expression – raising the hope that neoadjuvant chemotherapy (NACT) and neoadjuvant endocrine therapy (NET) could be used to “prime” tumor cells for subsequent HER-targeting by adjuvant systemic therapy in case of non- pathologic complete remission (pCR). Therefore, we investigated the dynamics of HER2 and HER3 expression in HER2 non-amplified breast cancer by retrospectively analyzing the immunohistochemical HER2 and HER3 protein expression in pre- and post-treatment tumor samples, treated with neoadjuvant systemic chemo- and endocrine therapy, from the prospectively randomized ABCSG 34 trial.&lt;/p&gt;&lt;p&gt;The trial design, inclusion criteria, and main clinical results of this trial were reported previously [&lt;span&gt;5&lt;/span&gt;].

Chronic bowel inflammation is one of the primary contributors to colorectal carcinogenesis [&lt;span&gt;2&lt;/span&gt;]. The persistent systemic inflammatory response associated with tumors contributes to cachexia and malnutrition in patient, leading to increased morbidity and mortality. Previous studies have demonstrated that Parkin acts as a negative regulator of necroptosis by binding to and polyubiquitinating RIPK3 (Receptor-Interacting Protein Kinase 3), a pivotal regulator of necroptosis [&lt;span&gt;3&lt;/span&gt;]. Loss of Parkin promotes hyperactivation of RIPK3, necroptosis, and inflammation-driven colorectal tumorigenesis. In colitis-associated models, inhibiting RIPK3 significantly reduces pro-inflammatory cytokine expression and cancerous polyp formation. However, the role of RIPK3 in tumorigenesis is complex [&lt;span&gt;4, 5&lt;/span&gt;], and the physiological relationship between Parkin and RIPK3 in vivo remains incompletely understood.&lt;/p&gt;&lt;p&gt;To further investigate the tumor-suppressive effect of Parkin through the inhibition of RIPK3 in vivo, we crossed &lt;i&gt;Prkn&lt;/i&gt; &lt;sup&gt;−/−&lt;/sup&gt; mice and &lt;i&gt;Ripk3&lt;/i&gt; &lt;sup&gt;−/−&lt;/sup&gt; mice to generate &lt;i&gt;Prkn&lt;/i&gt;/&lt;i&gt;Ripk3&lt;/i&gt; double-knockout (DKO) mice from heterozygous &lt;i&gt;Prkn&lt;/i&gt; &lt;sup&gt;+/−&lt;/sup&gt; &lt;i&gt;Ripk3&lt;/i&gt; &lt;sup&gt;+/−&lt;/sup&gt; breeding pairs [&lt;span&gt;6, 7&lt;/span&gt;]. The DKO mice were born at the expected Mendelian frequencies and were viable, healthy, and fertile (Figure 1A). Genotyping, genome sequence and Western blot analysis of mice from each group confirmed the successful generation of &lt;i&gt;Prkn&lt;/i&gt; &lt;sup&gt;−/−&lt;/sup&gt;, &lt;i&gt;Ripk3&lt;/i&gt; &lt;sup&gt;−/−&lt;/sup&gt; and DKO (Supplementary Figure S1, Supplementary Table S1). Long-term observations revealed that &lt;i&gt;Prkn&lt;/i&gt; &lt;sup&gt;−/−&lt;/sup&gt; mice had shorter lifespans and began to die around 8 months of age (Figure 1B). In contrast, &lt;i&gt;Ripk3&lt;/i&gt; single-knockout mice and DKO mice exhibited survival curves similar to those of wide-type (WT) mice. These results indicate that Parkin deficiency may induce abnormalities that contribute to reduced survival, and this phenotype is regulated by Ripk3.&lt;/p&gt;&lt;p&gt;As reported previously [&lt;span&gt;3&lt;/span&gt;], we found an increased frequency of rectal prolapse in &lt;i&gt;Prkn &lt;sup&gt;−/−&lt;/sup&gt;&lt;/i&gt; mice (Figure 1C, Supplementary Figure S2A). However, in DKO mice, the number of mice with rectal prolapse significantly decreased. Meanwhile, the weight of &lt;i&gt;Prkn &lt;sup&gt;−/−&lt;/sup&gt;&lt;/i&gt; mice was significantly less than that of WT mice (Supplementary Figure S2B). However, further knockout of &lt;i&gt;Ripk3&lt;/i&gt; in &lt;i&gt;Prkn &lt;sup&gt;−/−&lt;/sup&gt;&lt;/i&gt; mice did not rescue this low-weight phenotype. To explore this further, we dissected mice of all genotypes with similar ages and genders and found that the &lt;i&gt;Prkn &lt;sup&gt;−/−&lt;/sup&gt;&lt;/i&gt; mice had more polyps and obvious lesion in their small intestine, while knocking o","PeriodicalId":9495,"journal":{"name":"Cancer Communications","volume":"45 4","pages":"406-410"},"PeriodicalIF":20.1,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cac2.12648","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142926529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anaplastic lymphoma kinase (ALK) rearrangements occur in ∼5% of NSCLC cases, typically treated with ALK inhibitors, though resistance often develops [&lt;span&gt;1&lt;/span&gt;]. Immunotherapy has been explored for advanced or resistant ALK-positive NSCLC, but immune checkpoint blockade (ICB) treatments have shown limited clinical benefits [&lt;span&gt;1&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;A comprehensive study of ALK-positive NSCLC tumor microenvironment (TME) is needed to understand immunotherapy limitations and improve treatment strategies. We generated and collected single-cell RNA sequencing (scRNA-seq) and single-cell Assay for Transposase Accessible Chromatin with high-throughput sequencing (scATAC-seq) datasets from lung adenocarcinoma (LUAD) patients with ALK rearrangements and wild type without major oncogenic drivers (WT) (Supplementary Table S1). By comparing TME, we aimed to identify features explaining poor immunotherapy responses (Figure 1A).&lt;/p&gt;&lt;p&gt;After batch corrections for each of the RNA and ATAC profiles, we identified epithelial, stromal, and immune cells (Supplementary Figure S1A, Supplementary Table S2). From the immune compartment, we identified major cell types such as myeloid cells, T cells, natural killer (NK) cells, and B cells (Figure 1B, Supplementary Figure S1B, Supplementary Table S3). Integration of the RNA and ATAC profiles confirmed consistency between these two omics profiles (Supplementary Figure S1C-D). Compositional analysis revealed that ALK-positive samples showed an enrichment of innate immune cells (myeloid and NK cells) and depletion of adaptive immune cells (T and B cells) (Figure 1C, Supplementary Figure S1E-F), suggesting weak adaptive anti-tumoral responses in ALK-positive TME.&lt;/p&gt;&lt;p&gt;Oncogenic mutations primarily impact epithelial cells, so we classified epithelial cell malignancy with the cell-classifier and copy number variations (Supplementary Figure S1G-H) and measured &lt;i&gt;ALK&lt;/i&gt; and &lt;i&gt;PD-L1&lt;/i&gt; expression. Malignant cells expressing &lt;i&gt;ALK&lt;/i&gt; or &lt;i&gt;PD-L1&lt;/i&gt; were predominantly from ALK-positive malignant cells (Supplementary Figure S1I). We observed that ALK-positive tumors had a higher malignant-to-normal epithelial cell ratio than WT tumors (Figure 1D). Additionally, malignant cells in ALK-positive tumors exhibited increased stemness, indicating greater developmental potential (Figure 1E). Top 100 upregulated genes in ALK-positive tumors were linked to aggressive cancer pathways like epithelial-mesenchymal transition (EMT) and hypoxia [&lt;span&gt;2&lt;/span&gt;] (Figure 1F).&lt;/p&gt;&lt;p&gt;To identify malignant subsets with higher progression potential, we constructed developmental trajectories (Supplementary Figure S1J).

Accordingly, the annual incidence of soft tissue sarcomas (STS) has markedly increased since the early 2000s [&lt;span&gt;2, 3&lt;/span&gt;]. Likewise, there appears to be an overall increase in the incidence of bone sarcomas (BS) since 1975 [&lt;span&gt;4, 5&lt;/span&gt;]. In parallel, one study reports moderate improvement in the survival of adult patients with BS and STS up to 2007 [&lt;span&gt;6&lt;/span&gt;]. Previous studies were often based on cancer registries with low coverage rates [&lt;span&gt;3, 7, 8&lt;/span&gt;], focused on limited time periods [&lt;span&gt;3, 9, 10&lt;/span&gt;], or did not include data from recent years [&lt;span&gt;3, 6&lt;/span&gt;]. Thus, current data from high-income European countries with an advanced health care system on incidence and prognosis of sarcoma patients are scarce. Consequently, the purpose of this study was to analyse the incidence of and survival with BS and STS in the general population of Austria from 1983 to 2020. A detailed description of materials and methods is outlined in the Supplementary Materials (Supplementary Materials and Methods).&lt;/p&gt;&lt;p&gt;Across the 38-year observation period, 2,491 patients in Austria were diagnosed with BS (Supplementary Tables S1-S2, Supplementary Figure S1). Male-to-female ratio was 1.27, favouring males (range over the years: 0.56-1.23), which remained constant over time &lt;i&gt;(P =&lt;/i&gt; 0.529; Supplementary Table S3).&lt;/p&gt;&lt;p&gt;Throughout the observation period, mean age-adjusted BS incidence was 0.80 per 100,000 (95% confidence interval [CI]: 0.61-0.98; Figure 1A). We observed a significant increase in incidence from 1983 to 2020, with an average annual percentage change (AAPC) of 7.2% (95%CI: 6.2%-8.5%; &lt;i&gt;P&lt;/i&gt; &lt; 0.001; Supplementary Table S4). Similar results were obtained in a sensitivity analysis excluding the initial 7 years of the observation period (&lt;i&gt;ie&lt;/i&gt;, 1983-1989; AAPC: 1.5% [95%CI: 1.0%-2.1%]; &lt;i&gt;P&lt;/i&gt; &lt; 0.001) and chondrosarcoma diagnoses (AAPC: 5.8% [95%CI: 4.9%-7.2%]; &lt;i&gt;P&lt;/i&gt; &lt; 0.001; Supplementary Figure S2A; Supplementary Table S4).&lt;/p&gt;&lt;p&gt;Age at diagnosis of BS followed a bimodal distribution, with peaks in incidence around the age of 15 years and 70 years (Figure 1B), both in males and females (Supplementary Figure S3A). Notably, a shift towards increased BS incidence in older age groups was present in recent years (Supplementary Figure S4A, Supplementary Figure S5A). In a sensitivity analysis excluding all chondrosarcoma diagnoses, a similar pattern was observed (Supplementary Figure S2B).&lt;/p&gt;&lt;p&gt;Five-year relative survival was 65.9% (95%CI: 63.9%-67.9%).
