AI Article Synopsis
- The study aimed to assess the impact of the GRIK3 gene polymorphism (rs6691840) on alcohol dependence in a Polish population.
- Using DNA samples from both alcohol-dependent patients and healthy controls, various genetic analysis methods indicated no significant association between the GRIK3 polymorphism and alcohol dependence or its subgroups.
- The results reinforce previous findings, suggesting that the rs6691840 variant does not play a role in the development of alcohol dependence.
Article Abstract
Aim: The aim of this study was to evaluate the role of the glutamate receptor subunit-7 (GluR7, GRIK 3) rs6691840 (Ser310Ala, T928G) in the pathogenesis of alcohol dependence (AD).
Methods: DNA was provided from AD patients (n = 209) and healthy control subjects (n = 308) all of Polish descent. The history of alcoholism was obtained using the Polish version of the SSAGA (Semi-Structured Assessment for the Genetics of Alcoholism). We conducted case-control association study and transmission disequilibrium test (TDT). GRIK3 functional polymorphism was genotyped by the PCR-RFLP method.
Results: Analyses revealed that polymorphism Ser310Ala of GRIK3 gene is not associated with AD or any of its subgroups. TDT reveled an adequate transmission of both alleles in the group of alcohol families.
Conclusions: These findings replicate and extend our previous research results that do not support the hypothesis of the role of rs6691840 in the pathogenesis of AD.

Neuropathic pain (NP) imposes a significant burden on individuals, manifesting as nociceptive anaphylaxis, hypersensitivity, and spontaneous pain. Previous studies have shown that traumatic stress in the nervous system can lead to excessive production of hydrogen sulfide (HS) in the gut. As a toxic gas, it can damage the nervous system through the gut-brain axis.

Neuromuscular diseases usually manifest as abnormalities involving motor neurons, neuromuscular junctions, and skeletal muscle (SkM) in postnatal stage. Present in vitro models of neuromuscular interactions require a long time and lack neuroglia involvement. Our study aimed to construct rodent bioengineered spinal cord neural network-skeletal muscle (NN-SkM) assembloids to elucidate the interactions between spinal cord neural stem cells (SC-NSCs) and SkM cells and their biological effects on the development and maturation of postnatal spinal cord motor neural circuits.

The ENaC receptor acts as a taste receptor to recognize and perceive salty substances. This study explored the mechanisms by which the ENaC taste receptor recognizes and binds mushroom-derived salty peptides using molecular interaction and molecular simulation. The three subunits α, β, and γ of the ENaC taste receptor (SCNN1α, SCNN1β, and SCNN1γ) showed different recognition characteristics for the salty peptide.

In this study, we explored the efficacy and possible mechanisms in combination of CIMT and iTBS through behavioral evaluation, RNA sequencing, Golgi staining, transmission electronic microscope (TEM), high-performance liquid chromatography (HPLC), western blotting (WB) and immunofluorescence. Firstly, we observed that combination therapy is safe and effective, and it can significantly reduce the number of immature dendritic spines and increase the number of functional dendritic spines, the amount of glutamate (Glu) and the expression of Glu1 receptor (Glu1R).
