Thallium Induces Antiproliferative and Cytotoxic Activity in Glioblastoma C6 and U373 Cell Cultures via Apoptosis and Changes in Cell Cycle.

Neurotox Res 2022 Jun 27;40(3):814-824. Epub 2022 Apr 27.

Laboratorio de Aminoácidos Excitadores/Laboratorio de Neurofarmacología Molecular y Nanotecnología, Instituto Nacional de Neurología y Neurocirugía, 14269, Mexico City, Mexico.

Thallium (Tl) is a heavy metal that causes toxicity in several organs, including the brain. Its cytotoxic profile, combined with its affinity for tumor cells when used as a radioligand for labeling these cells, suggests its potential use as antitumor therapy. In this study, glioblastoma cell lines C6 (from rat) and U373 (from human) were exposed to increased concentrations of thallium(I) acetate (5, 10, 50, 100, or 200 µM) and several toxic endpoints were evaluated, including loss of confluence and morphological changes, loss of cell viability, changes in cell cycle, and apoptosis.

Light- and HO-Mediated Redox Transformation of Thallium in Acidic Solutions Containing Iron: Kinetics and Mechanistic Insights.

Environ Sci Technol 2022 May 18;56(9):5530-5541. Epub 2022 Apr 18.

Key Laboratory of Eco-environments in Three Gorges Reservoir Region, Ministry of Education, College of Environment and Ecology, Chongqing University, Chongqing 400044, China.

The redox transformation between the oxidation states of thallium (Tl(I) and Tl(III)) is the key to influencing its toxicity, reactivity, and mobility. Dissolved iron (Fe) is widely distributed in the environment and coexists at a high level with Tl in acidic mine drainages (AMDs). While ultraviolet (UV) light and HO can directly (by inducing Tl(III) reduction) and indirectly (by inducing Fe(III) to form reactive intermediates) impact the redox cycles of Tl in Fe(III)-containing solutions, the kinetics and mechanism remain largely unclear.

Contribution of heavy metals in PM to cardiovascular disease mortality risk, a case study in Guangzhou, China.

Chemosphere 2022 Jun 24;297:134102. Epub 2022 Feb 24.

School of Medicine, Jinan University, Guangzhou, 510632, China. Electronic address:

Heavy metals play an important role in inducing fine particulate matter (PM) related cardiovascular disease (CVD). However, most of the past researches concerned the associations between CVD mortality and the PM mass, which may not reveal the CVD mortality risk contributed by heavy metals in PM. This study explored the correlations between individual heavy metals in PM and CVD mortality, identified the heavy metals that significantly contribute to PM-related CVD, heart disease (HD), and cerebrovascular disease (CEV) mortality, and attempted to establish corresponding source control measures.

Assessment of potential human health risks in aquatic products based on the heavy metal hazard decision tree.

BMC Bioinformatics 2022 Feb 17;22(Suppl 5):620. Epub 2022 Feb 17.

Department of Food Science, National Taiwan Ocean University, Keelung City, 20224, Taiwan.

Background: Naturally existing and human-produced heavy metals are released into the environment and cannot be completely decomposed by microorganisms, but they continue to accumulate in water and sediments, causing organisms to be exposed to heavy metals.

Results: This study designs and proposes heavy metal hazard decision trees for aquatic products, which are divided into seven categories including pelagic fishes, inshore fishes, other fishes, crustaceans, shellfish, cephalopods, and algae. Based on these classifications, representative fresh and processed seafood products are at the root of the heavy metal hazard decision trees. Read More

Department of Agricultural Chemistry, College of Bio-Resources and Agriculture, National Taiwan University, Taipei, Taiwan. Electronic address:

Paddy soils contaminated by thallium (Tl) have been frequently reported; however, their ecotoxicological impact in the paddy field is less known. We used a novel soil-fish exposure system with larvae of rice fish medaka (Oryzias latipes) to assess the bioavailability of Tl from soils to fish and causal toxicity under simulated conditions of rice cultivation. Two acidic soils [Pingzhen (Pc) and Sankengtzu (Sk)] spiked with monovalent Tl [Tl(I), 75-250 mg/kg] released higher Tl into pore or overlying waters than neutral soils [Sangkang (Su)], which resulted in higher mortality to exposed fish.

Among transition and non-transition metals, thallium is a unique case of an element which, despite its known toxicity, provides interesting challenges through its biology and chemistry linked to diagnosis of human pathophysiologies. Poised to investigate in-depth the structural and electronic aspects of thallium involvement in physiological processes, the synthetic exploration of aqueous binary systems of Tl(I) with physiological binders from the family of hydroxycarboxylic acids (glycolic, lactic, mandelic and citric acid) was pursued in a pH-specific fashion. The isolated crystalline coordination polymers, emerging from that effort, were physicochemically characterized through elemental analysis, FT-IR, ESI-MS, H-/C-NMR, and X-ray crystallography.
