miR-429-3p mediates memory decline by targeting MKP-1 to reduce surface GluA1-containing AMPA receptors in a mouse model of Alzheimer's disease

Alzheimer's disease (AD) is a leading cause of dementia in the elderly. Mitogen-activated protein kinase phosphatase 1 (MKP-1) plays a neuroprotective role in AD. However, the molecular mechanisms underlying the effects of MKP-1 on AD have not been extensively studied. MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level, thereby repressing mRNA translation. Here, we reported that the microRNA-429-3p (miR-429-3p) was significantly increased in the brain of APP23/PS45 AD model mice and N2AAPP AD model cells. We further found that miR-429-3p could downregulate MKP-1 expression by directly binding to its 3'-untranslated region (3' UTR). Inhibition of miR-429-3p by its antagomir (A-miR-429) restored the expression of MKP-1 to a control level and consequently reduced the amyloidogenic processing of APP and Aβ accumulation. More importantly, intranasal administration of A-miR-429 successfully ameliorated the deficits of hippocampal CA1 long-term potentiation and spatial learning and memory in AD model mice by suppressing extracellular signal-regulated kinase (ERK1/2)-mediated GluA1 hyperphosphorylation at Ser831 site, thereby increasing the surface expression of GluA1-containing α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs). Together, these results demonstrate that inhibiting miR-429-3p to upregulate MKP-1 effectively improves cognitive and synaptic functions in AD model mice, suggesting that miR-429/MKP-1 pathway may be a novel therapeutic target for AD treatment.

Endocrine effects of three common gas signaling molecules in humans: A literature review.

Gases such as hydrogen sulfide, nitric oxide and sulfur dioxide have important regulatory effects on the endocrine and physiological processes of the body and are collectively referred to as "gas signaling molecules". These gas signaling molecules are also closely related to Alzheimer's disease, the inflammatory response and depression. In this paper, we introduce the production and metabolic pathways of NO, H2S and SO2 in living organisms and review the regulatory functions of gas signaling molecules in the endocrine system and their mechanisms in relation to their clinical applications. This work will provide a basis for finding targets for intervention and establishing novel prevention and treatment strategies for related diseases.

Level of IGF1 in follicular fluid associated with IVF pregnancy outcome in the application of growth hormone.

OBJECTIVES: The combination of growth hormone (GH) with gonadotropin was a prevalent method to improve clinical reproduction in adjuvant for assisted reproduction treatment (ART). However, the contradictory results from previous studies failed to confirm the benefits. The present study is focused on the mechanism analysis of GH-IGF1-gonadal axis in ART and the changes of IGF1 in follicular fluid among different types of patients. MATERIAL AND METHODS: We recruited 136 patients and divided them into eight groups according to their ages and ovarian reserves. The baseline characteristics of the study population were summarized. The therapeutic outcomes in the study population were observed. In the meantime, concentrations of IGF1 in follicular fluids from different types of patients who underwent GH strategy were measured by Western blot. The functional mechanism of GH-IGF1-gonadal axis in ART was also analyzed. RESULTS: We analyzed the baseline characteristics of the study population, the therapeutic outcome of GH-IGF-1-gonadal axis, as well as the relative protein level of IGF1 and IGFBP1 in follicular fluid from different groups. The chemical pregnancy rate was significantly increased in different degrees for groups with GH co-treatment compared to groups without GH co-treatment. The IGF1 in follicular fluid of patients under 35 years' old showed an upward trend compared with groups of poor, normal and high ovarian reserves. After GH induction, IGF1 in follicular fluid was significantly increased in patients over 35 years old. CONCLUSIONS: The study suggested that the application of GH might be beneficial to the pregnancy outcome in patients. GH application in patients older than 35 years might have a beneficial effect on pregnancy outcome via promoting the expression of IGF1. Our study indicates a different mechanism from GH application among younger and older patient in ART and provides a new clue for individual clinical treatment in infernity patients.

Treatment strategy of the scar uterus patients in assisted reproduction / 中国医师杂志

Objective:To investigate the effect of scar uterus on assisted reproduction treatment strategy.Methods:From January 1, 2017 to December 31, 2017, 109 cases of scar uterus group and 63 cases of vaginal delivery history group who underwent in vitro fertilization-embryo transfer (IVF-ET) assisted pregnancy fresh embryo transfer in our hospital were retrospectively analyzed. Results:⑴ There was no significant difference in the total amount of gonadotropin (Gn) and the total days of GN in patients <35 between scar uterus group and the vaginal delivery history group ( P>0.05), but there were significant differences in the number of oocytes, mature oocytes, two pronucleus (2PN) and excellent embryos between the scar uterus group and the vaginal delivery history group ( P<0.05). When the age was ≥35 years old, there was no significant difference in the total number of GN, the total days of GN, the number of oocytes obtained, the number of mature oocytes, the number of 2PN and the number of excellent embryos between the two groups ( P>0.05). ⑵ There were no statistically significant differences in clinical pregnancy rate and embryo implantation rate between the two groups of patients < 35 years old, no matter single embryo transplantation or double embryos transplantation. When transplant two embryos, the clinical pregnancy rate and embryo implantation rate in the scar uterus group were slightly lower than those in the vaginal delivery history group (57.57% vs 71.05% and 39.39% vs 47.37%, respectively), but with no significant difference ( P>0.05). There were no statistically significant differences in the clinical pregnancy rate and embryo implantation rate between single embryo transplantation and double embryo transplantation in patients≥35 years old ( P>0.05). ⑶ There were no statistically differences in biochemical pregnancy rate, early abortion rate, preterm birth rate and average newborn weight between the scar uterus group and the vaginal delivery history group ( P>0.05). Conclusions:Cesarean section may affect the ovarian function. For patients with previous cesarean section, early evaluation of ovarian function is recommended. Single embryo transfer does not reduce the outcome in IVF-ET. It is recommended to perform single embryo transfer for patients with scar uterus to reduce the risk during pregnancy of twin pregnancy.

Surface modification of PGP for a neutrophil-nanoparticle co-vehicle to enhance the anti-depressant effect of baicalein

Exploiting cells as vehicles combined with nanoparticles combined with therapy has attracted increasing attention in the world recently. Red blood cells, leukocytes and stem cells have been used for tumor immunotherapy, tissue regeneration and inflammatory disorders, and it is known that neutrophils can accumulate in brain lesions in many brain diseases including depression. -Acetyl Pro-Gly-Pro (PGP) peptide shows high specific binding affinity to neutrophils through the CXCR2 receptor. In this study, PGP was used to modify baicalein-loaded solid lipid nanoparticles (PGP-SLNs) to facilitate binding to neutrophils . Brain-targeted delivery to the basolateral amygdala (BLA) was demonstrated by enhanced concentration of baicalein in the BLA. An enhanced anti-depressant effect was observed and The mechanism involved inhibition of apoptosis and a decrease in lactate dehydrogenase release. Behavioral evaluation carried out with rats demonstrated that anti-depression outcomes were achieved. The results indicate that PGP-SLNs decrease immobility time, increase swimming time and climbing time and attenuate locomotion in olfactory-bulbectomized (OB) rats. In conclusion, PGP modification is a strategy for targeting the brain with a cell-nanoparticle delivery system for depression therapy.

Effect of combination of gastrodia and uncaria on pharmacokinetics of gastrodin and rhynchophylline / 中国中药杂志

To investigate the effect of the combination of gastrodia and uncaria on the pharmacokinetics of gastrodin and rhynchophylline, and determine their pharmacokinetic parameters after administration of the combination of gastrodia and uncaria at the ratio of 12∶9. Compared with uncaria group or gastrodia group, Cmax and AUC of both gastrodin and rhynchophylline were significantly increased, and tmax was retroceded by 1.5 h for rhynchophylline and 0.25 h for gastrodin. The change of tmax resulted in a 1.25 h difference in the peak time between gastrodin and rhynchophylline , which was the same between them. Uncaria shows a more effect in suppressing hyperactive Yang, while gastrodia has a balancing effect by nourishing Yin and suppressing hyperactive Yang. As a result, gastrodia could exert the effect in nourishing Yin and suppressing effect of uncaria, which could avoid the deficiency of Yang affecting Yin due to mono-treatment of uncaria. On one hand, the enhanced AUC and Cmax of gastrodin could increase the average plasma drug concentration of gastrodin, and remedy the losing effect of uncaria at the early stage; On the other hand, the increased AUC and Cmax of rhynchophylline could make up the quick elimination of gastrodia in vivo at the late stage. Their combination could lead to an increased anti-hypertensive effect with the balance of Yin and Yang. They showed unique advantages compared with simple dosage increase of western medicines. The results were consistent with the principle of TCM treatment for the hypertension due to hyperactivity of the liver Yang. In short, this study gives a good pharmacokinetic explanation of the balance of Yin and Yang and TCM treatment for both symptoms and root cause.
