Comparative Bioactivity of Marine Macroalgae and Microalgae From the Brazilian Coast

This study demonstrates that extracts from Brazilian marine macroalgae (*Amansia multifida*, *Enantiocladia duperreyi*) and microalgae (*Chaetoceros muelleri*, *Thalassiosira pseudonana*) exhibit significant antimicrobial and antioxidant activities with low to moderate toxicity, highlighting their potential as sources of bioactive compounds for bioprospecting.

Expression profiles of lncRNAs H19, SPRY4-IT1, and XIST and their association with IDO1 and TDO2 in breast cancer

This study demonstrates that breast cancer patients exhibit significantly altered expression levels of lncRNAs H19, SPRY4-IT1, and XIST alongside elevated serum IDO1 and TDO2 concentrations, with specific correlations between these markers suggesting their combined role in immune-metabolic dysregulation and potential utility as biomarkers for disease progression.

Ultra-Processed Food Consumption and Epigenetic Regulation: A Multi-Cohort Study of DNA Methylation Changes

This multi-cohort study demonstrates that ultra-processed food consumption is associated with a reproducible and modifiable DNA methylation signature across diverse study designs, implicating key genes involved in endothelial signaling, DNA damage response, neuronal function, and metabolic regulation.

CAPRA predicts single-cell transcriptional responses to genetic perturbations with response anchoring and residual correction

The paper introduces CAPRA, a novel response-anchored model that predicts single-cell transcriptional responses to genetic perturbations by combining control states, gene embeddings, and learned corrections, thereby achieving superior accuracy and interpretability in both single- and double-gene tasks compared to existing methods.
