Yet, the exact chain of events triggered by curcumin to suppress tumors, and the mediators involved in this anti-tumor process, continue to be largely mysterious. Our genetic studies focused on how curcumin's action is mediated by the p53/miR-34 pathway. Cellular analyses were carried out on isogenic colorectal cancer cell lines, rendered deficient in p53, miR-34a, or miR-34b/c after being exposed to curcumin. Various molecular analyses, including Western blot, qPCR, and qChIP, were used to assess NRF2 target genes after siRNA-mediated inhibition and ectopic expression of NRF2. Intravenous administration of CRC cells occurred. Injection of NOD/SCID mice and subsequent lung-metastasis formation were tracked using longitudinal, non-invasive imaging techniques. CRC cells exposed to curcumin exhibited apoptosis and senescence, along with a suppression of migration and invasion, all independent of p53's activity. Curcumin, by inducing ROS, activated the KEAP1/NRF2/ARE signaling pathway. Significantly, curcumin activated the expression of miR-34a and miR-34b/c through a mechanism that involves ROS/NRF2 but not p53. The presence of multiple ARE motifs within the promoter regions of miR-34a and miR-34b/c allowed NRF2 to directly induce their expression. Curcumin eliminated the repression effect of IL6 and hypoxia on miR-34a and miR-34b/c. Following the removal of miR-34a and miR-34b/c, curcumin's capacity to induce apoptosis and senescence diminished, and the inhibition of cell migration and invasion by curcumin or ectopic NRF2 was abolished. Through a miR-34a-dependent process, curcumin within CRC cells facilitated MET and effectively obstructed the development of lung metastases in mice. Subsequently, our results indicated that the addition of curcumin may improve the therapeutic outcomes of 5-FU in CRC cells missing p53 and miR-34a/b/c. Activation of the KEAP1/NRF2/miR-34a/b/c signaling axis by curcumin exhibits tumor-suppressive activity, suggesting a novel therapeutic application involving the activation of miR-34 genes in tumors.

In various cancers, the catalytic subunit of polycomb repressive complex 2 (PRC2), enhancer of zeste homolog 2 (EZH2), is overexpressed and acts as an oncogene through mechanisms reliant upon or independent of catalytic activity. Still, the mechanisms associated with ovarian cancer (OC) are not well-characterized.
Immunohistochemistry (IHC) staining was used to assess EZH2 and H3K27me3 levels in 105 OC patients, who were subsequently stratified based on these measurements. The study of EZH2 binding sites, both canonical and non-canonical, was performed via chromatin immunoprecipitation sequencing (ChIP-Seq). The EZH2 solo targets emerged from a joint interpretation of ChIP-Seq and RNA sequencing datasets. To ascertain EZH2's involvement in ovarian cancer cell growth, in vitro and in vivo studies were undertaken.
Among OC patients, a subset characterized by elevated EZH2 expression coupled with diminished H3K27me3 levels presented with the poorest prognosis, leaving therapeutic choices constrained. We observed that the degradation of EZH2, but not its catalytic inhibition, significantly prevented OC cell proliferation and tumor formation both in laboratory experiments and in living organisms. A genome-wide examination of chromatin and transcriptome profiles revealed substantial EZH2 presence, occurring at loci defined by H3K27me3 modification and independently at promoters not regulated by PRC2, thus establishing a non-canonical function for EZH2 in ovarian cancer. EZH2's mechanistic effect on ovarian cancer (OC) growth is linked to its transcriptional upregulation of IDH2. This augmented tricarboxylic acid (TCA) cycle activity and consequential metabolic rewiring are critical contributors to the cancer's progression.
EZH2's novel oncogenic contribution to ovarian cancer (OC) is revealed by these data, along with potential therapeutic strategies for OC, which center on targeting EZH2's non-catalytic activity.
Analysis of these data suggests a new oncogenic function of EZH2 in ovarian cancer (OC), which identifies potential therapeutic strategies for OC by targeting the non-catalytic activity of EZH2.

The mortality rate and poor outlook associated with ovarian cancer (OC) are largely due to the absence of specific biomarkers and distinctive clinical signs early in the disease's development. Although CEBPG is a significant regulator in tumorigenesis, the exact manner in which it influences ovarian cancer progression is yet to be elucidated.
TCGA data and immunohistochemical staining (IHC) of tissue microarrays provided a framework for evaluating CEBPG expression levels in ovarian cancer (OC). cytomegalovirus infection A diverse set of in vitro tests were executed, including evaluations of colony formation, proliferation, migration, and invasion processes. An orthotopic mouse model of OC was established to permit in vivo studies. Observing mitochondrial changes through electron microscopy, quantifying ROS levels, and measuring cell sensitivity to drugs using a CCK8 assay confirmed the presence of ferroptosis. Through the utilization of CUT&Tag and dual luciferase reporter assays, the interaction between CEBPG and SLC7A11 was validated.
Ovarian cancer (OC) tissues displayed a significantly higher expression of CEBPG when compared to benign ovarian tissues. Analysis of datasets and patient samples showed a clear correlation between elevated CEBPG expression and a poorer prognosis for OC patients. In contrast, silencing CEBPG, as evidenced in ovarian cancer cell lines and in vivo models of orthotopic ovarian cancer, resulted in a decrease in ovarian cancer progression. Significantly, a role for CEBPG in circumventing ferroptosis in ovarian cancer cells was discovered through RNA sequencing, a finding with implications for ovarian cancer progression. CUT&Tag and dual luciferase reporter assays unraveled the inner mechanisms behind CEBPG's influence on OC cell ferroptosis, demonstrating its effect on the transcriptional regulation of SLC7A11.
Our research identified CEBPG as a novel transcriptional controller of OC ferroptosis, highlighting its potential use in predicting clinical courses and as a therapeutic agent.
Our study revealed CEBPG as a novel transcriptional controller of OC ferroptosis, potentially offering insights for predicting clinical outcomes and as a possible therapeutic target.

Volcanism is a potent force capable of producing substantial effects on the environment, including alterations in global climate and events leading to mass extinctions. In contrast, the effects of monogenetic volcanism are frequently assessed as circumscribed in volcanological research. This work provides a pioneering interdisciplinary study on the socio-ecological effects of monogenetic volcanism in the crucial La Garrotxa Volcanic Field (GVF), located in Girona, NE Iberia, a region with intense historical monogenetic volcanic activity. Analyses of a sedimentary sequence originating in the GVF facilitated the discovery of previously unknown volcanic events occurring between 14 and 84 ka cal BP. Their volcanic stratigraphy and age were determined, and the influence of environmental changes on landforms, vegetation, aquatic life, and human populations was revealed. In addition, we model the principal palaeoenvironmental transformations brought about by the volcanic eruptions, examining episodes of fire and the ensuing disruptions to plant cover, hydrological processes, and aquatic environments. Based on the archaeological record, the last hunter-gatherer communities displayed resilience over extensive territories, confronting vulnerabilities arising from volcanic activity. Their adaptive nomadic routines and foraging strategies served as effective risk management against volcanic eruptions and their environmental consequences.
