Functional analysis of thiamine pyrophosphate-responsive riboswitches in human bacterial pathogens of the ESKAPE group using a dual-luciferase reporter gene assay

Journal of Bacteriology
Thiamine pyrophosphate (TPP)-responsive riboswitches are genetic elements in bacteria that regulate the expression of genes coding for proteins involved in the biosynthesis and transport of thiamine (vitamin B1). Following uptake, cytoplasmic thiamine is

Targeting eIF5A combats breast cancer progression by ClpP‐dependent mitochondrial oxidative stress

Interdisciplinary Medicine, EarlyView.
This study identified the eIF5A‐ClpP axis as a key driver of breast cancer progression. Targeting eIF5A suppresses tumor growth by inducing ClpP‐dependent mitochondrial oxidative stress, revealing a novel therapeutic vulnerability. Abstract Breast cancer (BC) poses a persistent global health challenge, necessitating new therapeutic targets.

Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

Journal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Evaluating the combined toxicity of Penicillium mycotoxins in absorption, metabolism, and excretion systems

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Penicillium mycotoxins, including ochratoxin A (OTA), citrinin (CIT), and cyclopiazonic acid (CPZ), frequently co‐occur in food commodities, contributing to chronic low‐level dietary exposure. However, current risk assessments often consider these toxins individually, overlooking potential interaction effects.

TPP and Environmental Regulation

, 2019
Abstract This chapter examines the environment-related provisions of the Trans-Pacific Partnership Agreement (TPP) to assess how and how much they contribute to a larger megaregulatory program for the Asia-Pacific region. TPP calls for “high levels” of environmental protection and effective enforcement; incorporates duties from several ...
