Despite advances in our understanding of molecular aspects oncogenesis, cancer remains a leading cause death. The malignant behavior cell is driven by the inappropriate activation transcription factors. In particular, signal transducers and activators (STATs), which regulate many critical cellular processes such as proliferation, apoptosis, differentiation, are frequently activated inappropriately wide spectrum human cancers. Multiple signaling pathways converge on STATs, highlighting their importance development progression oncogenic diseases.

Breast cancer (BC) is the most prevalent malignancy among women worldwide. Traditional research models such as primary cell and patient-derived tumor xenografts (PDTXs) have limitations. Cancer cells lack a microenvironment (TME) genetic diversity, whereas PDTXs are expensive time-consuming preparation protocol. Therefore, alternative warranted. Patient-derived organoids (PDOs) promising in vitro model. They mimic TME, gene expression, types of original tissues. PDOs been successfully developed from various cancers, including BC. In this review, we focused on value limitations BC research, their characteristics potential drug development, personalized therapy, immunotherapy, application prospects testing prognosis.

Background: TSPX is an X-linked tumor suppressor that was initially identified in non-small cell lung cancer (NSCLC) lines. However, its expression patterns and downstream mechanisms NSCLC remain unclear. This study aims to investigate the functions of by identifying potential targets their correlation with clinical outcomes. Methods: RNA-seq transcriptome pathway enrichment analyses were conducted on TSPX-overexpressing lines, A549 SK-MES-1, originating from adenocarcinoma squamous carcinoma subtypes, respectively. In addition, comparative performed using data specimens (515 adenocarcinomas 502 carcinomas) Cancer Genome Atlas (TCGA) database. Results: TCGA analysis revealed significant downregulation tumors compared adjacent non-cancerous tissues (Wilcoxon matched pairs signed rank test p < 0.0001). Notably, levels inversely correlated stage, higher associated better outcomes improved survival adenocarcinoma, a subtype (median extended 510 days; log-rank test, = 0.0025). lines regulates various genes involved cancer-related signaling pathways viability, consistent suppression proliferation culture assays. patient (log-rank 0.016 4.3 × 10−10) identified, including EGFR pathway-related AREG, EREG, FOSL1, MYC, which downregulated. Conclusions: Our results suggest plays critical role suppressing progression downregulating pro-oncogenic genes, particularly those pathway, upregulating suppressors, especially adenocarcinoma.

Triple-negative breast cancer (TNBC) is an aggressive subtype of characterized by the absence estrogen receptors (ER), progesterone (PR), and HER2 expression. While TNBC relatively less common, accounting for only 10–15% initial diagnosis, due to its nature, it carries a worse prognosis in comparison hormone receptor-positive counterparts. Despite significant advancements screening, treatment cancer, remains important public health burden. Following with chemotherapy, surgery, radiation, over 40% patients experience relapse within 3 years achieve least benefit from post-mastectomy radiation. The tumor microenvironment environment (TME) pivotal initiation, progression, immune evasion, resistance, prognosis. TME complex network that consists cells, non-immune soluble factors located region adjacent modulates therapeutic response differentially between TNBC. mechanisms underlying radiation resistance remain unclear, immunosuppressive has been implicated chemotherapeutic resistance. Radiation therapy (RT) known alter TME; however, changes elicited are poorly date, whether these contribute unknown. This review delves into distinct characteristics TME, explores how RT influences dynamics, examines radiosensitization, radioresistance, responses.

Preclinical in vitro and vivo models remain indispensable tools cancer research. These classic models, including two- three-dimensional cell culture techniques animal are crucial for basic translational studies. However, each model has its own limitations typically does not fully recapitulate the course of human disease. Therefore, there is an urgent need development novel, advanced systems that can allow efficient evaluation mechanisms underlying progression, more accurately reflect disease pathophysiology complexity, effectively inform therapeutic decisions patients. especially important rare cancers, such as neuroblastoma, where availability patient-derived specimens could be used potential therapy screening limited. Neuroblastoma modeling further complicated by heterogeneity. In this review, we present current status preclinical neuroblastoma research, discuss their characteristics emphasizing strengths limitations, describe necessity clinically relevant approaches.
