Phytoremediation of Cadmium: Physiological, Biochemical, and Molecular Mechanisms

Biology, 2020
Cadmium (Cd) is one of the most toxic metals in the environment, and has noxious effects on plant growth and production. Cd-accumulating plants showed reduced growth and productivity.

Transcriptional breakpoints as predictors of thermal thresholds in a climate‐impacted stenothermal fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biogeography of ectotherms is greatly influenced by their thermal tolerance, which is expected to be tightly coupled to aerobic performance. However, preferred temperatures of ectotherms often deviate substantially from aerobic performance optima. This suggests that

Zinc Supplementation Forms Influenced Zinc Absorption and Accumulation in Piglets

Animals, 2020
The study aimed at determining the effect of different zinc (Zn) supplementation forms on Zn accumulation, activities of Zn-containing enzymes, gene expression of metallothionein (MT), and Zn transporters in piglets.

ZmMS1 coordinates ROS homeostasis, lipid allocation, and male fertility for maize breeding applications

Journal of Integrative Plant Biology, EarlyView.
The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

Analysis of metallothionein gene structure in sterlet (Acipenser ruthenus) during copper exposure

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2017
Aquatic organisms present, not only simple sources of accumulated metal, but can interact with metals, altering their toxicity. Due to exposition of biosphere with metals, organisms have developed various defense mechanisms to protect themselves against ...

Study of interrelations between resistance to cisplatin and composition of low molecular weight thiols in murine leukemia L1210 cell lines

Біологічні студії, 2012
Cis-dichlorodiammineplatinum (II), commonly known as cisplatin, is a widely used anticancer drug. However, the therapeutic efficacy of the drug is limited due to various dose-limiting side effects and development of acquired resistance. The resistance of

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

Plant Biotechnology Journal, EarlyView.
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

Glial Metallothionein

Neurosignals, 1994
The metal-binding protein, metallothionein (MT) has been found to be primarily produced by astrocytes in the rat and human brain. This review discusses the relationship of glial MT to the distribution of metals in the brain, possible roles of MT in the regulation of glial enzymes and other glial proteins, and the possible role of a subset of MT ...

Transfer of Potentially Toxic Metal(loid)s From Ultramafic Soils in a Tri‐Trophic Food Chain Experiment

Ecological Research, Volume 41, Issue 5, September 2026.
Potentially toxic metal(loid)s (PTMs) bioaccumulated across a plant‐herbivore‐predator food chain. Irrespective of soil concentrations, female crickets actively selected PTM‐enriched leaves, while predatory mantids showed no developmental impairment. Trophic transfer of PTMs was rather influenced more by a function of intrinsic species traits than by ...

Overcoming Radiation Resistance: Ferroptosis Induction to Sensitize Solid Tumors to Radiation Therapy

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Radiation therapy (RT) is a mainstay of treatment for a myriad of cancers, often utilized for tumors that are unable to be resected, as well as an adjunct to surgery and chemotherapy. Unfortunately, many cancers are resistant to RT‐induced damage and subsequent cell death.
