Upregulated PKM2 Protects Dopaminergic Neurons From Oxidative Damage Through Nrf2 Transactivation in an MPTP‐Induced Mouse Model of Parkinson's Disease

CNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
Oxidative stress induced by MPTP promotes hnRNP A1/A2–dependent alternative splicing toward PKM2 in dopaminergic neurons. Elevated PKM2 transactivates Nrf2, enhances antioxidant gene expression, and protects neurons from oxidative damage and degeneration.

Effects of the pesticide dieldrin on incubation of the earthwonn Eisenia letitia (Oligochaeta) [PDF]

, 2017
The effects of a long-term exposure of newly hatched earthworms to a dieldrin-treated culture medium were examined with regard to the determination of incubation period and hatching success of cocoons ultimately produced by the exposed worms.

Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Inter and intraspecific variability of dieldrin accumulation in Cucurbita fruits: New perspectives for food safety and phytomanagement of contaminated soils

, 2023
International audienceDue to past agricultural practices, it is common to identify arable soils contaminated with persistent and potentially toxic organochlorine pesticides (OCPs). Occurrence of OCPs, including dieldrin, in vegetables can lead to chronic

Functional Profiling Discovers the Dieldrin Organochlorinated Pesticide Affects Leucine Availability in Yeast

, 2013
Exposure to organochlorinated pesticides such as dieldrin has been linked to Parkinson’s and Alzheimer’s diseases, endocrine disruption, and cancer, but the cellular and molecular mechanisms of toxicity behind these effects remain largely unknown.

THE PHARMACOLOGICAL PROPERTIES OF THE INSECTICIDE DIELDRIN

, 1954
The effects of dieldrin (hexachloro-epoxy-octahydro-dimethanonaphthalene) were studied in acute experiments on cats and rabbits. When injected intravenously or intra-arterially, it caused excitation of the central nervous system, which resulted in ...
