Drug addiction is a complex disorder caused by multiple factors, including environmental and genetic factors. Stress-related genes such as Galanin (GAL) and Oxytocin (OXT) have been linked to the reward pathways that contribute to the development and progression of substance addiction. This study aimed to explore the correlation between several polymorphisms of stress-related genes and drug addiction among Jordanian males.
The study included 500 participants, consisting of both healthy controls and drug-addicted Jordanian males. The genetic material and clinical data were collected, and 18 SNPs in four candidate genes were genotyped using the Sequenom MassARRAY® system. Statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 25.0 and the SNPStats website.
The study identified a significant correlation between three SNPs of the GAL gene and drug addiction, specifically rs3136544, rs3136541, and rs694066. The study also found that different genotypes of these variants were significantly associated with drug addiction. Furthermore, different haplotypes of the GAL, GALR1, and OXTR polymorphisms were also significantly correlated with drug addiction. The study also identified a correlation between several drug addiction features and the studied variants, including the association of rs2717162 of Galanin receptor 1 (GALR1) with age at use onset and the association of rs3136541 of GAL with the type of substance and number of substances used.
Stress-related genes can play a significant role in the development and progression of addiction among the Jordanian population, and further investigations are necessary to understand the underlying mechanisms better and improve future treatment strategies.
Liraglutide, a type2 diabetes mellitus (T2DM)-related treatment, improves glycemic control and reduces the risks of adverse cardiovascular events in T2DM patients. However, the underlying mechanisms of the above-mentioned beneficial effects of Liraglutide are not well understood. To have better understanding of these mechanisms, we aimed to study the metabolic impacts of Liraglutide on the metabolome and corresponding pathways in T2DM patients, especially metabolism plays a very fundamental role in health and diseases and is influenced by drugs. In this study, plasma samples collected from T2DM patients (n = 20) and taken pre- and post-Liraglutide treatment were used for untargeted metabolomics analyses, including metabolome profiling and metabolic pathway/network analyses. The metabolome profiling analyses identified 93 endogenous metabolites that were significantly affected by Liraglutide treatment where 49 and 44 metabolites were up and down regulated, respectively. Liraglutide caused metabolic alterations impacting metabolic pathways such as pentose and glucuronate interconversion and alanine, aspartate and glutamate metabolism in T2DM patients. Since the last-mentioned pathways are affected by Liraglutide, it could explain partially the overall beneficial effects of Liraglutide in T2DM, especially that glucuronate interconversion pathway is known by its important roles in eliminating toxic and undesirable substances from the human body to maintain good health status. In addition, the metabolism of amino acids induced by Liraglutide could improve the function of immune cells, strengthening the immunity of T2DM patients. Also, Liraglutide induced the level of other metabolites that help in the defense mechanism against oxidative events. Overall, the findings of this study provide a deeper understanding of the underlying mechanisms involved in the beneficial effects of Liraglutide in T2DM from the metabolic aspect.
The impact of Engineered nanomaterials (ENMs) (i.e., Zinc Oxide nanoparticles (ZnO NPs)) on human health has been investigated at high and unrealistic exposure levels, overlooking the potential indirect harm of subtoxic and long exposures. Therefore, this study aimed to investigate the impacts of subtoxic concentrations of zinc oxide (ZnO NPs) on breast cancer cells’ response to Doxorubicin. Zinc oxide nanoparticles caused a concentration-dependent reduction of cell viability in multiple breast cancer cell lines. A subtoxic concentration of 1.56 µg/mL (i.e., no observed adverse effect level) was used in subsequent mechanistic studies. Molecularly, miRNA profiling revealed significant downregulation of 13 oncogenic miRNAs (OncomiRs) in cells exposed to the sub-toxic dose of ZnO NPs followed by doxorubicin treatment. Our comprehensive bioinformatic analysis has identified 617 target genes enriched in ten pathways, mainly regulating gene expression and transcription, cell cycle, and apoptotic cell death. Several tumor suppressor genes emerged as validated direct targets of the 13 OncomiRs, including TFDP2, YWHAG, SMAD2, SMAD4, CDKN1A, CDKN1B, BCL2L11, and TGIF2. This study insinuates the importance of miRNAs in regulating the responsiveness of cancer cells to chemotherapy. Our findings further indicate that being exposed to environmental ENMs, even at levels below toxicity, might still modulate cancer cells’ response to chemotherapy, which highlights the need to reestablish endpoints of ENM exposure and toxicity in cancer patients receiving chemotherapeutics.
