- چکیده انگلیسی: Regenerative medicine (RM) is a developing multidisciplinary science that uses different principles and methods of other fields or sciences for tissue regeneration, repair or replacement. Gene therapy refers to transferring genes or gene expression regulator factors for the desired purposes. In some cases, gene therapy plays an important role in regenerative medicine by modulating stem cells from different sources. Genetic heterogeneity of individuals can affects the results of gene therapy or other therapies in RM. This is why personal genomics should be considered in RM and is called personalized regenerative medicine (PRM). The purpose of PRM is to employ strategies and methods tailored to the individual’s genetics in order to efficiently reconstruct or substitute various parts of the body. In this study, the strategies and recent advances in bone regeneration such as gene therapy, epigenetic-based therapies, RNA-based therapy and CRISPR/Cas9 system with an attitude to personalized medicine are introduced.

- چکیده:
- چکیده انگلیسی: Background: The amygdala is one of the nerve centers involved in drug reward. It is suggested that the central nucleus of the amygdala (CeA) is involved in morphine dependency. The CeA gamma-aminobutyric acid-ergic (GABAergic) system is a mediator of morphine rewarding effects. In this research, the effects of stimulation or inhibition of CeA GABA type B (GABAB) receptors on sensitization acquisition to morphine-induced reward was evaluated in Wistar female rats using conditioned place preferential (CPP) method.Methods: Wistar female rats provided by Shahid Beheshti University, Tehran, Iran, were allocated into 17 groups including 7 groups of determining morphine dose-response, 2 groups of sensitivity and control, and 8 groups of different doses of agonists and antagonists in the acquisition stage (n = 7 in each group). Various quantities of morphine (0.5, 1, 2.5, 5, 7.5, 10 mg/kg of animal weight) were used to determine the effective and neutral doses of morphine. After 5 days from the start of the surgery, sensitization was induced. After the end of the sensitization period, CPP was conducted. Baclofen and CGP35348, as an agonist and antagonist of GABAB respectively, with the dose of 1.5, 6 and 12 μg/rat were inserted to the CeA, ten minutes before taking morphine.Findings: Administration of baclofen had no significant effect on the acquisition of morphine sensitization. In contrast, injection of CGP35348 reduced the sensitivity to morphine.Conclusion: GABA receptors can be effective in reducing morphine tendency by specific receptors, so these sites can be important therapeutic targets in counteracting the effects of drug abuse.
