Although they have traditionally been used for anticancer drug screening, their potential to address broader aspects of aggressive tumor biology has received comparatively less attention. EC/EAC exhibits several characteristics associated with advanced malignancy, including rapid tumor growth, angiogenesis, immune dysregulation, metabolic changes, therapeutic resistance, and complex interactions between the tumor and host. These features make EC/EAC a useful complementary model for studying different aspects of tumor progression. However, research using these models has largely focused on transcriptional changes and individual signalling pathways, while post-transcriptional regulatory mechanisms remain less explored. In particular, the role of the RNA-induced silencing complex (RISC), a major component of microRNA-mediated gene regulation, is still poorly understood in EC/EAC. In this review, we discuss the major limitations of current EC/EAC research, including the limited use of multi-omics approaches, single-cell and spatial analyses, functional genomics, immune checkpoint profiling, and integrated systems-level studies. We further discuss how incorporating RISC-centered regulatory networks with emerging approaches such as CRISPR-based studies, spatial transcriptomics, and metabolic profiling could provide deeper mechanistic insights and improve the translational value of these models.

Among many tumors that are arginine-auxotrophic due to downregulation of ASS1 are hepatocellular carcinoma, melanoma, and subsets of oral cancers, and are therefore susceptible to depletion of extracellular arginine. Although recombinant human arginase has advanced to preclinical and clinical trials, issues such as immunological reactions and limited stability have sparked interest in alternative sources. Marine microorganisms, especially from deep-sea environments, are known to produce unique and stable enzymes with high catalytic efficiency and are less prone to protein denaturation. As a result of their remarkable stability in harsh conditions and variety of structures, marine microbial arginases have emerged as the top candidates for investigation. In addition to remaining active at varying pH, salinity, and temperatures, these enzymes offer a versatile platform for protein engineering and therapeutic optimisation. This review focuses on the biochemical and structural properties of arginase, compares microbial and human forms, and explores the mechanisms of its antitumor action, including tumor cell growth inhibition, angiogenesis modulation, and immune suppression within the tumor microenvironment.

The bioactive compounds found in the essential oil extracted from Piper betle leaves are especially abundant and are thought to have a major role in the plant's medicinal potential. In the current study, the antioxidant and anticancer properties of essential oil extracted from Piper betle leaves were objectively evaluated using in vitro experimental methods. To thoroughly investigate the essential oil's capacity to reduce oxidative stress, its antioxidant activity was evaluated using a variety of free radical scavenging assays, such as the DPPH, Hydrogen Peroxide, Superoxide Dismutase, and ABTS assays. The anticancer activity was investigated against human oral carcinoma (KB) cell lines by assessing cytotoxicity and membrane damage. The MTT assay was performed to assess cell viability at doses between 6.25 and 100 µg/mL, with an IC<sub>50</sub> value determined to be 22.8 µg/mL, the essential oil demonstrated considerable antiproliferative activity and significant, concentration-dependent cytotoxicity against KB cells. In addition, the essential oil demonstrated pronounced antioxidant activity across all tested assays.

The TME does not act as a passive scaffold but active regulation of tumor initiation, growth, metastatic dissemination, immune evasion and therapeutic resistance in terms of coordinated metabolic, signaling and immunological networks. Adaptive metabolic reprogramming and phenotypic plasticity in both cancer and stromal compartments were found in microenvironmental stressors like hypoxia, nutrient deprivation, and extracellular acidosis. The adaptations maintain invasive, cancer stem cell persistence, immune suppression and survival upon therapeutic pressure. Crosstalk between cells metabolism, exosome-based communication, and extracellular matrix reorganization all determine ecosystem-level resilience disrupting traditional cancer therapies. Within the framework of this commentary, we generalize emerging evidence that places the TME at a hub of metastasis and drug resistance, and we focus on metabolic plasticity, stromal re-programming and immune-metabolic competition. Based on the integrative multi-omics framework by Mir et al., we expand on the way genomics, transcriptomics, proteomics, metabolomics, and spatial profiling are redefining precision oncology by solving intratumoral heterogeneity and determining ecosystem-wide vulnerabilities. Lastly, we emphasize the possibilities of translational multi-omics-informed targeting of metabolic and stromal dependencies to break tumor ecosystem resilience and resulting clinical responses to be more durable.

Comparative evaluation of three independent gene expression datasets yielded 194 overlapping differentially expressed genes (DEGs) enriched in pathways central to tumor progression. A protein-protein interaction network was constructed, and hub genes were prioritized using the Maximal Clique Centrality algorithm, revealing critical nodes involved in melanoma biology. Drug-gene interaction analysis via DGIdb identified carboplatin as a multi-target compound interacting with CDKN1A, BRCA1, PTEN, and AKT1. Although carboplatin, often combined with paclitaxel, is already utilized clinically for advanced or treatment-refractory melanoma, its multi-target molecular effects in relation to melanoma transcriptomic alterations remain insufficiently defined. Experimental validation in B16F0 melanoma cells demonstrated dose- and time-dependent cytotoxicity, with an IC₅₀ of approximately 17 µM at 48 h. RT-qPCR analysis showed increased expression of CDKN1A, BRCA1, and PTEN, alongside reduced AKT1 expression, indicating activation of DNA damage response pathways and reinforcement of tumor-suppressive signaling.

This study investigated the effects of exosomes derived from dimethyl itaconate (DMI)-treated macrophages on epithelial-mesenchymal transition (EMT), apoptosis, migration, and EMT-related miRNAs in MCF7 breast cancer cells. U937 macrophages were treated with 250 µM DMI for 48 h. Exosomes (DMI-EXO) were subsequently isolated, characterized, and used to treat MCF7 cells.
