Pan-inhibition of super-enhancer-driven oncogenic transcription by next-generation synthetic ecteinascidins yields potent anti-cancer activity.

Nat Commun

January 2025

IGBMC, Institut de Génétique et de Biologie Moléculaire et Cellulaire Illkirch Cedex, C.U. Equipe Labélisée Ligue contre le Cancer, Strasbourg, France.

The plasticity of cancer cells facilitates their ability to adopt heterogeneous differentiation states, posing a significant challenge to therapeutic interventions. Specific gene expression programs, driven in part by super-enhancers (SEs), underlie cancer cell states. Here we successfully inhibit SE-driven transcription in phenotypically distinct metastatic melanoma cells using next-generation synthetic ecteinascidins.

The increasing number of contaminants released into the environment necessitates innovative strategies for their detection and identification, particularly in complex environmental matrices like hospital wastewater. Hospital effluents contain both natural and synthetic hormones that might significantly contribute to endocrine disruption in aquatic ecosystems. In this study, HT-EDA has been implemented to identify the main effect-drivers (testosterone, androsterone and norgestrel) from hospital effluent using microplate fractionation, the AR-CALUX bioassay and an efficient data processing workflow.

The sex chromosomes contain complex, important genes impacting medical phenotypes, but differ from the autosomes in their ploidy and large repetitive regions. To enable technology developers along with research and clinical laboratories to evaluate variant detection on male sex chromosomes X and Y, we create a small variant benchmark set with 111,725 variants for the Genome in a Bottle HG002 reference material. We develop an active evaluation approach to demonstrate the benchmark set reliably identifies errors in challenging genomic regions and across short and long read callsets.

Introduction: The prognostic value of PAM50 intrinsic subtypes (IS), cell cycle, and immune-related gene expression in HR+ /HER2- advanced breast cancer (BC) treated with CDK4/6 inhibitors (CDK4/6i) and endocrine therapy (ET) in a first-line metastatic setting is unclear. This study evaluates these biomarkers in metastatic biopsies from patients diagnosed with HR+ /HER2- advanced BC.

Background And Objective: Given the uncertainty regarding the role of radical nephroureterectomy (RNU) as part of a multimodal treatment strategy for upper tract urothelial carcinoma (UTUC) patients with cN+ disease, we aimed to perform a systematic review and meta-analysis of the corresponding literature.

Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we identified 17 observational comparative and noncomparative studies, published between January 2000 and September 2024, evaluating UTUC patients with cTanyN+M0 disease (P) who received RNU as part of a multimodal treatment strategy (I), as compared with any treatment strategy if applicable (C), to assess oncological or postoperative outcomes (O). Meta-analyses were further performed, as appropriate.

CIC biomaGUNE, Basque Research and Technology Alliance (BRTA), Donostia-San Sebastián 20014, Spain.

In three-dimensional (3D)-printed tissue models, sensitive, noninvasive techniques are required to detect changes in hydrogel structure caused by cellular remodeling. We demonstrate herein that circular dichroism (CD) spectroscopy provides a reliable method for detecting hydrogel structural variations. We probe directly the plasmonic optical activity of chiral gold nanorods (c-AuNRs) embedded within the hydrogel matrix, in response to variations in the local environment.

Laboratory of Food Chemistry and Toxicology, Department of Preventive Medicine and Public Health, Food Science, Toxicology and Forensic Medicine, Faculty of Pharmacy, University of Valencia, Avda. Vicent Andrés Estellés, s/n, 46100 Burjassot, Spain.

Mycotoxins pose significant health risks due to their prevalence in food products and severe health implications, including carcinogenicity. This study investigates the bioavailability of mycotoxins aflatoxin B1 (AFB1), ochratoxin A (OTA), and zearalenone (ZEN) individually and combined, in the presence of identified polyphenols from tiger nut beverage (TNB) and tiger nut by-product (TNBP) using the in vitro model Caco-2 cells, which simulates the human intestinal barrier. The objective is to understand how bioactive compounds from TNBP can mitigate the effects of AFB1, OTA and ZEN (and their combination) by bioavailability interference, contributing to safer food products and innovative food safety strategies.

Electronic address:

Coffee pulp (CP) is the by-product of coffee processing that urgently needs to be revalorized using sustainable technologies. This work applied a design of experiment (DoE) for modeling the extraction of bioactive compounds from CP using supercritical carbon dioxide (sc-CO) with ethanol as a co-solvent under variable conditions (temperature, pressure, and ethanol percentage). Considering extraction efficiency (per unit of CP) and extraction selectivity (per unit of extract), results showed that ethanol percentage significantly enhanced the efficiency of total phenolic content, as well as the selectivity of chlorogenic acid and protocatechuic acid (p < 0.

Layer-by-Layer (LbL) self-assembly encapsulation is a promising technology for the protection and delivery of lactic acid bacteria. However, laboratory-scale encapsulation is often time-consuming, involves intensive protocols tailored for small-scale operations, requires substantial amounts of energy and water, and results in a low yield of encapsulated biomass. Scaling-up this process to a bench-bioreactor scale is not simply a matter of increasing culture volume as different key parameters (not particularly relevant at lab scale) become critical, including biomass production, the number of polymer layers, and the biomass-to-polymer mass ratio.
