Prostate cancer remains one of the most prevalent malignancies and a major cause of cancer‑related mortality among men worldwide. Despite widespread use of prostate‑specific antigen testing, current diagnostic approaches suffer from low specificity and limited ability to distinguish between indolent and aggressive disease, resulting in overdiagnosis and overtreatment. Advances in molecular biology, genomics and metabolomics have led to the identification of novel biomarkers that have potential for improving the precision of prostate cancer diagnosis, prognosis and therapy. The present review provides a comprehensive overview of emerging prostate cancer biomarkers, including genetic (such as , and ), RNA‑based (such as PCA3 and miRNAs), metabolic (such as citric acid and polyamines) and methylation markers (such as , and ). These biomarkers not only enhance diagnostic accuracy but also facilitate risk stratification, prediction of therapeutic response and real‑time disease monitoring through liquid biopsy technologies. Moreover, integrating multi‑omics data with artificial intelligence and machine learning may further improve early detection and personalized treatment strategies. Overall, the development and clinical implementation of these biomarkers represent a transformative step toward precision medicine in prostate cancer, enabling earlier diagnosis, optimized therapy selection and improved patient outcomes.

Gastric cancer (GC) is a major global health burden, ranking fifth in incidence and third in cancer‑related mortality. By 2040, there are expected to be ~1.8 million new cases and 1.3 million fatalities associated with GC. Spasmolytic polypeptide‑expressing metaplasia (SPEM) is a central component of gastric precancerous lesions, which remodels the gastric mucosa in response to injury through a lineage of mucus‑secreting cells. Interleukins (ILs) are the communication means for innate and adaptive immune cells as well as non‑immune cells and tissues. Their complex network regulation contributes to the development of SPEM and is a key driver in the transformation of SPEM to GC. The present review systematically described the IL‑related mechanisms underlying the formation and progression of SPEM and categorizes the roles of different ILs by family. In addition, the molecular association between IL dynamics and SPEM following infection is explored, and various SPEM experimental model characteristics and IL‑based therapeutic strategy advances and limitations are discussed. The clinical translation of IL‑targeted therapies is limited, but the development of therapies that target pathogenesis specifically and the enhancement of IL therapy combinations with other therapeutic options may improve efficacy and reduce side effects. Increased understanding of the causes of SPEM and the mechanisms underlying GC may open up new avenues for early detection and targeted therapy.

Lung cancer remains a leading cause of cancer‑related death. Despite advances in targeted therapies and immunotherapy, treatment outcomes remain suboptimal due to tumor heterogeneity and therapeutic resistance. The tumor microenvironment (TME), a dynamic ecosystem comprising immune cells, stromal components, extracellular matrix and bioactive molecules, serves a critical role in promoting tumor progression and resistance. The present review comprehensively analyzes the molecular mechanisms underlying TME‑mediated immune evasion, and resistance to chemotherapy, radiotherapy and immunotherapy. In addition, emerging therapeutic strategies targeting the TME are highlighted, such as immune microenvironment modulation, metabolic and epigenetic interventions, and nanotechnology‑based drug delivery systems. By integrating multi‑omics datasets and spatial transcriptomics, TME‑directed interventions are moving toward biomarker‑guided, personalized regimens.

Following the publication of the above paper, it was drawn to the Editor's attention by an interested reader that the middle and right‑hand protein blots shown for the RIPK4 data in Fig. 2B (relating to the PANC‑1‑Rsh1 and PANC‑1‑Rsh2 experiments) were strikingly similar to western blot data shown in Fig. 3B for the RAF‑1 data (and the same PANC‑1‑Rsh1 and PANC‑1‑Rsh2 experiments), albeit the bands were presented with different exposures/a change in contrast, also with apparent horizontal flipping and vertical resizing. Upon contacting the authors, they realized that errors had been made during the assembly of the experimental images presented in Fig. 3B. These errors were likely to have resulted from oversights made during the process of data consolidation and figure assembly; specifically, this led to the inadvertent use of incorrect images for the RAF‑1 western blot results in both the PANC‑1 cell line (as was correctly identified by the interested reader on PubPeer) and in the Capan‑1 cell line (which the authors identified themselves upon performing their own subsequent review). The authors were also able to present photos of the raw, unedited versions of the gels to the Editorial Office. A revised version of Fig. 3, now showing the correct data for the RAF‑1 blots for both the PANC‑1 and Capan‑1 cell lines, as specified above, is shown on the next page. The authors confirm that the errors made in assembling Fig. 3 did not have a major impact on the conclusions reported in the above article, and they thank the Editor of for allowing them the opportunity to publish a Corrigendum. Furthermore, all the authors agree to the publication of this Corrigendum, and apologize to the readers for any inconvenience caused.

Breast cancer is characterized by notable heterogeneity and remains one of the leading causes of cancer‑related death among women. Autophagy, a process by which cells use lysosomes to degrade cytoplasmic proteins and damaged organelles, is not only associated with chemotherapy resistance, but is also involved in immune‑mediated tumor cell killing and immune evasion, making it a promising target for cancer therapy. Pharmacological inhibition of autophagy in breast cancer cells suppresses tumor progression. In the present study, the small molecular compound FZU‑0045‑053 (053) was identified, which exhibited autophagic and immunomodulatory effects. The effect of 053 on autophagy regulation in breast cancer cells was evaluated using transmission electron microscopy, an mRFP‑GFP‑ microtubule‑associated protein 1 light chain 3 (LC3) tandem fluorescent adenovirus, the CYTO‑ID Autophagy Detection Kit and western blot analysis. Cell viability was subsequently assessed with proliferation assay and ATP assay kits. Apoptosis induction and the expression of immune‑related molecules were measured by flow cytometry. Furthermore, a triple‑negative breast cancer mouse model was established to validate the antitumor and autophagy‑modulating effects of 053 using immunofluorescence and immunohistochemical staining. Finally, a 4T1 syngeneic mouse model was utilized to corroborate the immunomodulatory effects of 053 through immunohistochemistry and flow cytometric analysis. The findings indicated that 053 regulated autophagy in the breast cancer cell lines MDA‑MB‑231 and MCF‑7, similar to the late autophagy inhibitor chloroquine. This regulation resulted in the accumulation of autophagic substrates, specifically LC3‑II and sequestosome 1, by blocking autophagic flux. By blocking autophagy flux, 053 suppressed proliferation, induced apoptosis and ultimately restored chemosensitivity in MDA‑MB‑231 cells. In addition, the MDA‑MB‑231 xenograft model indicated that 053 inhibited autophagy by blocking autophagic flux, which lead to the accumulation of LC3 and sequestosome 1. 053 also negatively regulated the expression of programmed death‑ligand 1 (PD‑L1) in tumor cells. The 4T1 xenograft model showed that 053 had a notable immune‑promoting effect, whereby it not only negatively regulated the expression of PD‑L1 in tumor cells but also modulated T cell activation and proliferation by downregulating the expression of co‑inhibitory molecules (T‑cell immunoglobulin and mucin‑domain containing‑3 and programmed cell death protein 1) on T cells and upregulating co‑stimulatory molecules (4‑1BB, OX40 and inducible T‑cell co‑stimulator). xenograft models demonstrated that 053 had notable antitumor effects and high biosafety, with improved antitumor efficacy when combined with the chemotherapy drug gemcitabine. In summary, 053 can block autophagy and promote antitumor immune responses, showing promise as a new generation of adjuvant drugs for tumor chemotherapy and immunotherapy.

Hepatocellular carcinoma (HCC) continues to rank as a predominant contributor to cancer‑related mortality on a global scale, attributed to its insidious onset and unfavorable prognosis. The ribosomal protein lateral stalk subunit P0 (RPLP0) has recently gathered widespread attention as a crucial factor in the pathological progression of various neoplasms; however, its exact role in HCC remains inadequately defined. Consequently, the present study endeavored to shed light on the function and mechanistic underpinnings of RPLP0 in HCC and assess its clinical significance and potential as a therapeutic target. qPCR and western blot analyses indicated that RPLP0 was markedly upregulated in HCC, with its elevated levels correlating with poorer survival outcomes. Silencing RPLP0 expression suppressed the proliferative, invasive, migratory, and epithelial‑mesenchymal transition (EMT) abilities of HCC cells, while concurrently promoting apoptosis, autophagy, and G/M cell cycle arrest, as evidenced by CCK‑8, colony formation, Transwell assays and flow cytometry analysis, respectively. Moreover, the findings revealed that RPLP0 downregulation mediated the suppression of the JAK2/STAT3 pathway through reactive oxygen species (ROS) accumulation, which in turn downregulated c‑Myc expression. Furthermore, chromatin immunoprecipitation and dual luciferase assays demonstrated that c‑Myc directly bound to the promoter sequence of RPLP0, thereby augmenting its transcriptional activity. In summary, the current study highlighted that RPLP0 establishes a feedback circuit with c‑Myc by facilitating JAK2/STAT3 pathway activation through suppressing ROS levels, while c‑Myc reciprocally activates RPLP0, forming a regulatory circuit loop that drives HCC progression. Thus, targeting the c‑Myc/RPLP0/ROS/JAK2/STAT3 axis emerges as a promising therapeutic strategy for the management of HCC.

Obesity is a global epidemic strongly associated with increased breast cancer (BC) risk and mortality, particularly in postmenopausal women. Obesity‑induced chronic breast inflammation drives carcinogenesis via dysregulated adipokine signaling (leptin and adiponectin), insulin resistance, hyperinsulinemia and pro‑inflammatory cytokines (TNF‑α and IL‑6). These factors activate oncogenic pathways (NF‑κB and PI3K/AKT/mTOR pathways), which promote DNA damage, cell proliferation and immunosuppression. Clinically, obesity is associated with advanced tumor presentation, reduced treatment efficacy and poorer survival compared with those of normal‑weight patients with BC. Despite progress, the molecular interactions between obesity‑related inflammation and BC remain incompletely understood, and diagnostic/prognostic tools for obese patients require refinement. The present review synthesizes current evidence on obesity‑BC mechanisms and their clinical translation to inform prevention and precision oncology strategies.

Gastric cancer (GC) ranks among the most prevalent malignancies worldwide and is associated with high mortality rates. Ephrin‑B2 (EFNB2), a membrane‑bound ligand that interacts with Eph receptor tyrosine kinases, has been implicated in various cancer‑related biological processes; however, its precise role in GC remains poorly understood. By integrating data from multiple public databases with immunohistochemical analyses of tissue microarrays, significant upregulation of EFNB2 expression in GC specimens compared with paired adjacent normal tissue was demonstrated. Elevated EFNB2 levels were associated with the poor overall survival and disease‑free survival in patients with GC. EFNB2 knockdown inhibited cellular proliferation and viability, increased apoptosis, and induced cell cycle arrest at the G/G phase in GC cells. By contrast, EFNB2 overexpression resulted in the opposite oncogenic effects. Mechanistically, rescue experiments identified the Wnt/β‑catenin signaling cascade as the primary molecular pathway mediating EFNB2‑driven tumorigenic effects. These results were further validated using cell‑derived xenograft models, which confirmed the key role of Wnt/β‑catenin pathway activation in EFNB2‑induced tumor progression. Collectively, these results suggested that EFNB2 represents a promising molecular target for therapeutic intervention in GC.

Biliary tract cancer (BTC) encompasses a group of aggressive malignancies arising from the bile duct epithelium, including gallbladder cancer and cholangiocarcinoma, which are characterized by aggressive progression, frequent metastases and poor prognoses. BTC accounts for ~3% of all digestive system tumors, with a 5‑year overall survival rate of <20%. BTC presents a clinical challenge. Despite multidisciplinary therapeutic approaches incorporating surgery, chemotherapy and radiotherapy, persistent obstacles, including high tumor recurrence rates (>50%) and the development of treatment resistance remains, underscoring the urgent need for novel treatment strategies such as targeted therapies and immunotherapies. Ferroptosis, a distinct mechanism of regulated cell death triggered by lipid peroxidation, serves critical roles in disease occurrence and progression. Increasing evidence supports the potential of ferroptosis as a targeted therapy in malignancies, with emerging implications for personalized BTC treatment. The present review investigated the molecular mechanisms and signaling pathways that govern ferroptosis, the advances in the understanding of ferroptosis during the initiation and progression of BTC, and the translation potential of ferroptosis for precision therapeutics. By integrating current knowledge, the present study aimed to provide theoretical suggestions for future mechanistic investigations and clinical studies of ferroptosis‑based interventions for patients with BTC.

Gastric cancer (GC) has a high incidence, resistance to chemotherapeutic drugs and a bleak prognosis. () can promote GC development through Correa's cascade by impacting various forms of programmed cell death (PCD). As an iron‑dependent form of PCD, ferroptosis has emerged as a major focus in biomedical research. Notably, there have been developments in elucidating the mechanisms underlying ferroptosis dysregulation throughout Correa's cascade. On one hand, targeting ferroptosis may provide a promising direction for the development of drugs for chronic atrophic gastritis (CAG) and intestinal metaplasia (IM). On the other hand, targeting ferroptosis in GC may be a potential option to overcome the challenges in conventional therapies such as resistance to chemotherapy. Consequently, the present review aims to deliver a comprehensive understanding of the mechanisms underlying ferroptosis dysregulation in ‑associated GC and summarize the latest progress of ferroptosis‑related studies in CAG, IM and GC. The present study identifies key regulators of ferroptosis at distinct pathological stages, thereby providing insight of novel strategies for the management of precancerous lesion‑related diseases and GC.

Transition‑metal nanoparticles (NPs) have been extensively studied owing to their unique physical and chemical properties, ability to form a variety of nanostructures and targeting properties. After surgery, chemotherapy, radiotherapy and targeted therapy, immunotherapy has emerged as a major strategy for cancer treatment. In particular, immune checkpoint inhibition has attracted much attention in preclinical and clinical applications. The combination of transition‑metal NPs with tumor immunotherapy offers great potential. Therefore, the present review focused on four major transition‑metal NPs (Au, Ag, Cu and Fe NPs) and their respective categories, presented their characteristics and roles in the biomedical field and discussed their potential toxicities. In addition, the mechanisms of action of different tumor immunotherapies and the applications of transition‑metal NPs in tumor immunotherapy are discussed. The current status of, and challenges associated, with the clinical transformation of transition‑metal NPs in tumor immunotherapy are described to provide ideas for the subsequent development and clinical application of transition‑metal NPs.

Colorectal cancer (CRC) represents a major malignancy within the digestive tract, with its incidence and mortality rates steadily increasing annually, posing a severe threat to human health. Despite the extensive clinical utilization of diverse chemotherapeutic agents, their propensity for deleterious side effects and the emergence of drug resistance can impede patient compliance, consequently culminating in chemotherapy failure. Consequently, the quest for novel therapeutic agents with high efficacy and minimal toxicity has become increasingly urgent. To address this critical clinical dilemma, there is an imperative need to develop effective and well‑tolerated anti‑CRC drugs. Plant‑based antioxidants (PBAs) are now understood to possess diverse biological activities, thereby offering significant advantages with respect to clinical anti‑CRC applications. Compared with synthetic chemical agents, they are ubiquitous in natural sources, possess high safety profiles and can act as detoxifying or sensitizing agents when combined with conventional therapies in CRC, such as chemotherapy or radiotherapy. Hence, the present review systematically reviewed current research on PBAs for CRC treatment from the perspective of bioactive compounds, with the aim of offering theoretical foundations and reference values for future studies and clinical applications of PBAs in CRC therapies.

Germ cell tumors (GCTs) are rare, heterogeneous neoplasms derived from primordial germ cells. Although they typically develop in the gonads, they may also arise in extragonadal locations along the midline of the body. Approximately 90% of patients respond well to cisplatin‑based chemotherapy; however, ~30% exhibit treatment resistance. Epithelial‑mesenchymal plasticity (EMP), a recognized hallmark of cancer, has been implicated in promoting metastasis and chemoresistance. Nonetheless, studies investigating the specific role of EMP in GCT treatment resistance remain limited. The present review compiles key studies on GCTs, EMP markers and cisplatin resistance using both and models; it highlights the roles of associated genes, transcription factors and proteins, identifying potential therapeutic targets. Advancing our understanding of EMP and identifying novel therapeutic targets may support the development of treatment strategies that complement or replace cisplatin. This, in turn, could improve survival outcomes and create new avenues for molecular research and clinical applications.

Mitophagy, a selective autophagy process that targets damaged mitochondria, plays a critical role in cellular homeostasis and disease progression, including tumorigenesis. Ras homolog family member T1 (RHOT1), a mitochondria‑associated protein, has been reported to regulate mitochondrial dynamics and energy metabolism. However, its role in gastric cancer (GC) remains unclear. The present study aimed to investigate the function of RHOT1 in GC progression and its mechanistic link with mitochondrial quality control. To achieve this, RHOT1 was silenced in GC cells and its effect on the PINK1/Parkin pathway, mitochondrial homeostasis and cellular behavior examined. The study employed qPCR and western blotting to evaluate gene and protein expression, siRNA transfection to silence RHOT1 and flow cytometry, CCK‑8 proliferation, wound‑healing, and Transwell assays to investigate mitochondrial function and cellular phenotypes. Silencing RHOT1 reduced mRNA expression by 59.75% (P=0.025) and mRNA expression by 65.12% (P=0.0189), indicating suppressed mitophagy. This was accompanied by an 84.73% increase in reactive oxygen species (P<0.001) and a 36.94% decrease in mitochondrial membrane potential (P=0.0061). Silencing RHOT1 further caused G/G phase arrest and increased apoptosis (P<0.05), thereby markedly inhibiting the proliferation, invasion and migration of GC cells. The present study revealed that RHOT1 drives the malignant phenotype of GC through regulation of mitochondrial quality control and induction of oxidative stress, providing a rationale for developing novel anti‑tumor strategies by targeting mitochondrial function. RHOT1 may serve as a biomarker for prognostic assessment and individualized treatment of GC.

Following the publication of the above paper, a concerned reader drew to the Editor's attention that, for the immuno-histochemistry images shown in Fig. 6, the Control/PCNA and Control/p27kip1 panels appeared to be duplicates of each other, where the results of differently performed experiments were intended to have been portrayed. The authors were contacted by the Editorial Office to offer an explanation for this potential anomaly in the presentation of the data in this paper, although up to this time, no response from them has been forthcoming. Owing to the fact that the Editorial Office has been made aware of potential issues surrounding the scientific integrity of this paper, we are issuing an Expression of Concern to notify readers of this potential problem while the Editorial Office continues to investigate this matter further.
