Abstract
Chronic exposure to stress is a non-adaptive situation that is associated with mitochondrial dysfunction and the accumulation of reactive oxygen species (ROS), especially superoxide anion (SA). This accumulation of ROS produces damage-associated molecular patterns (DAMPs), which activate chronic inflammatory states and behavioral changes found in several mood disorders. In a previous study, we observed that an imbalance of SA triggered by rotenone (Ro) exposure caused evolutionarily conserved oxi-inflammatory disturbances and behavioral changes in Eisenia fetida earthworms. These results supported our hypothesis that SA imbalance triggered by Ro exposure could be attenuated by lithium carbonate (LC), which has anti-inflammatory properties. The initial protocol exposed earthworms to Ro (30 nM) and four different LC concentrations. LC at a concentration of 12.85 mg/L decreased SA and nitric oxide (NO) levels and was chosen to perform complementary assays: (1) neuromuscular damage evaluated by optical and scanning electron microscopy (SEM), (2) innate immune inefficiency by analysis of Eisenia spp. extracellular neutrophil traps (eNETs), and (3) behavioral changes. Gene expression was also evaluated involving mitochondrial (COII, ND1), inflammatory (EaTLR, AMP), and neuronal transmission (nAchR α5). LC attenuated the high melanized deposits in the circular musculature, fiber disarrangement, destruction of secretory glands, immune inefficiency, and impulsive behavior pattern triggered by Ro exposure. However, the effects of LC and Ro on gene expression were more heterogeneous. In summary, SA imbalance, potentially associated with mitochondrial dysfunction, appears to be an evolutionary component triggering oxidative, inflammatory, and behavioral changes observed in psychiatric disorders that are inhibited by LC exposure.

Fluoride as a Potential Repressor of Glycogen Metabolism in Skeletal Muscle Cell Line CCL136. Molecules 2023; 28:6065. [PMID: 37630316 PMCID: PMC10459804 DOI: 10.3390/molecules28166065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 07/30/2023] [Accepted: 08/11/2023] [Indexed: 08/27/2023] Open
Abstract
The exposure of humans to fluorine is connected with its presence in the air, food and water. It is well known that fluorides even at a low concentration but with long time exposure accumulate in the body and lead to numerous metabolic disorders. Fluoride is recognised as a factor modulating the energy metabolism of cells. This interaction is of particular importance in muscle cells, which are cells with high metabolic activity related to the metabolism of glucose and glycogen. In someone suffering from chronic fluoride poisoning, frequent symptoms are chronic fatigue not relieved by extra sleep or rest, muscular weakness, muscle spasms, involuntary twitching. The aim of this study was to examine the effect of fluorine at concentrations determined in blood of people environmentally exposed to fluorides on activity and expression of enzymes taking part in metabolism of muscle glycogen. CCL136 cells were cultured under standard conditions with the addition of NaF. The amount of ATP produced by the cells was determined using the HPLC method, the amount and expression of genes responsible for glycogen metabolism using WB and RT PCR methods and the amount of glycogen in cells using the fluorimetric and PAS methods. It has been shown that in CCL136 cells exposed to 1, 3 and 10 μM NaF there is a change in the energy state and expression pattern of enzymes involved in the synthesis and breakdown of glycogen. It was observed that NaF caused a decrease in ATP content in CCL136 cells. Fluoride exposure also increased glycogen deposition. These changes were accompanied by a decrease in gene expression and the level of enzymatic proteins related to glycogen metabolism: glycogen synthase, glycogen synthase kinase and glycogen phosphorylase. The results obtained shed new light on the molecular mechanisms by which fluoride acts as an environmental toxin.

Abstract
Retinal degenerative diseases are characterized by photoreceptor cell loss. Photoreceptor cell loss leading to retinal degeneration can be induced by N-methyl-N-nitrosourea (MNU), which was widely used to mimic the pathology. However, the mechanism by which MNU induces photoreceptor cell loss is still largely unknown. The purpose of the present study was to investigate whether phosphorylation of glycogen synthase kinase-3β (p-GSK-3β) is a potent mediator of MNU-induced retinal degeneration and how p-GSK-3β affects the process. MNU-induced photoreceptor cell loss was evaluated in Sprague-Dawley (SD) rat retinas. GSK-3β and Akt expression levels did not change during MNU-induced retinal degeneration but the phosphorylation of GSK-3β and Akt was decreased by MNU treatment. Lithium chloride (LiCl), which increases p-GSK-3β level and active-β-catenin level, reversed retinal degeneration induced by MNU treatment. These results suggest that GSK-3β activation is closely related to photoreceptor cell loss and that the application of the GSK-3β inhibitor LiCl could activate Wnt/β-catenin signaling pathway and reduce photoreceptor cell loss induced by MNU. Our findings indicate that inhibition of GSK-3β activation may be a potential therapeutic target for retinal degeneration induced by photoreceptor cell loss.
