Abstract
Diabetic cognitive dysfunction (DCD) is a complication of diabetes that seriously affects quality of life. Glucocorticoid-induced transcript 1 (GLCCI1) has been found to be involved in inflammation, apoptosis and autophagy in various diseases. However, the distribution of GLCCI1 in the brain and its role in DCD have not yet been revealed. In addition, the potential therapeutics effects of salidroside (SAL), a phenyl propyl glycoside compound known for its neuroprotective effects in treating DCD are unknow. In the present study, we found that GLCCI1 was localized in hippocampal neurons. C57BL/6 J mice with DCD presented downregulation of GLCCI1 and Bcl-2 and upregulation of p-STAT3/STAT3, Bax, Cleaved Caspase-3/Caspase-3. Overexpression of GLCCI1 or SAL administration relieved DCD, reversed the changes in the expression of these cytokines, and alleviated morphological alterations in hippocampal neurons. Interestingly, SAL alleviated DCD and attenuated the expression of GLCCI1 and p-STAT3, showing similar effects as GLCCI1 overexpression. These findings suggest that the GLCCI1/STAT3 axis plays a crucial role in DCD and is involved in SAL-mediated attenuation of DCD.

Abstract
Type 2 diabetes mellitus (T2DM) is characterized by insulin resistance and a relative deficiency of insulin. This study aims to screen T2DM-related maker genes in the mouse extraorbital lacrimal gland (ELG) by LASSO regression.C57BLKS/J strain with leptin db/db homozygous mice (T2DM, n = 20) and wild-type mice (WT, n = 20) were used to collect data. The ELGs were collected for RNA sequencing. LASSO regression was conducted to screen marker genes with the training set. Five genes were selected from 689 differentially expressed genes by LASSO regression, including Synm, Elovl6, Glcci1, Tnks and Ptprt. Expression of Synm was downregulated in ELGs of T2DM mice. Elovl6, Glcci1, Tnks, and Ptprt were upregulated in T2DM mice. Area under receiver operating curve of the LASSO model was 1.000(1.000-1.000) and 0.980(0.929-1.000) in the training set and the test set, respectively. The C-index and the robust C-index of the LASSO model were 1.000 and 0.999, respectively, in the training set, and 1.000 and 0.978, respectively, in the test set. In the lacrimal gland of db/db mice, Synm, Elovl6, Glcci1, Tnks and Ptprt can be used as marker genes of T2DM. Abnormal expression of marker genes is related to lacrimal gland atrophy and dry eye in mice.

Abstract
Gene expression microarray and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to measure the expression of miR-126. In model of diabetic nephropathy, we demonstrated that miR-126 expression was down-regulated, compared with control group. Down-expression of miR-126 promoted cell apoptosis and increased inflammation (as indicated by the levels of IL-1β, IL-6, IL-18 and TNF-α) of diabetic nephropathy in vitro. miR-126 over-expression led to significant inhibition of cell apoptosis and suppressed inflammation (IL-1β, IL-6, IL-18 and TNF-α). However, the down-expression of miR-126 suppressed the protein expression of VEGF, PI3K and p-AKT in diabetic nephropathy in vitro. On the contrary, over-expression of miR-126 induced the protein expression of VEGF, PI3K and p-AKT in diabetic nephropathy in vitro. The inhibition of VEGF increased the effect of miR-126 down-expression on apoptosis and inflammation in diabetic nephropathy in vitro. We investigated the specific function of miR-126 in patients with diabetic nephropathy and its possible mechanism.

Abstract
BACKGROUND AND AIMS Epigenetic changes play a role in the occurrence of asthma. In this study, we evaluated the methylation status of glucocorticoid-induced transcript 1 (GLCCI1) and assessed its associations with asthma and asthma severity. MATERIALS AND METHODS Peripheral blood mononuclear cells were harvested from 33 severe asthma patients, 84 mild-moderate asthma patients and 79 healthy controls of Han nationality. GLCCI1 methylation were screened using the MassArray Epityper platform (Agena). We also conducted mRNA sequencing of GLCCI1-knockout mice to further explore possible functions of this gene. RESULTS We found 5 GLCCI1 methylation sites independently correlated with asthma (adjusted p < 0.05) and perform well in asthma prediction with optimum area under the curve (AUC) value was 0.846 (p < 0.0001). In asthmatic group, only one sites independently associates with severe asthma. Area under the curve in predicting severe asthma is comparable with forced expiratory volume in 1 s predicted (AUC 0.865 and 0.857, p = 0.291). Spearman correlate analysis denoted GLCCI1 low methylation is associates with its low expression in asthma PBMCs. Its reduced level may influence PI3k-Akt and MAPK pathways by the results of RNA sequencing of GLCCI1-knockout mice (adjusted p value < 0.01). CONCLUSIONS Our research indicates a low GLCCI1 methylation level in asthma with certain sites are lower in severe asthma group. These GLCCI1 methylation sites may be contributed to detect asthma and asthma severity.

Association between Renal Podocalyxin Expression and Renal Dysfunction in Patients with Diabetic Nephropathy: A Single-Center, Retrospective Case-Control Study. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7350781. [PMID: 32337271 PMCID: PMC7157790 DOI: 10.1155/2020/7350781] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 01/23/2020] [Accepted: 02/12/2020] [Indexed: 01/16/2023]
Abstract
This retrospective study investigated whether podocalyxin expression in renal biopsies and urine of patients with diabetic nephropathy (DN) is associated with renal function. This retrospective study included 32 patients with nephropathy, secondary to type 2 diabetes treated at the First Hospital of Lanzhou University (January 2010 to January 2015). Compared with the control group, the DN group had a significantly lower renal expression of podocalyxin and higher urinary podocalyxin/creatinine ratio. Patients with DN were divided into the high and low expression groups according to podocalyxin expression in renal tissues. Patients in the low expression group had longer diabetes duration, lower plasma albumin and eGFR, higher glycated hemoglobin (HbA1c), 24 h urinary protein, serum creatinine, and urinary podocalyxin/creatinine ratio, and more severe glomerular, tubulointerstitial, and renal interstitial inflammation than patients in the high expression group (all P < 0.01). The renal survival rate was significantly lower in the low expression group than in the high expression group (P < 0.01). Single-factor Cox regression analysis showed that reduced podocalyxin expression and increased urinary podocalyxin excretion were associated with poor renal outcome. Measuring podocalyxin levels in renal tissues and urine could help evaluate the progression of DN.

Abstract
Background As a fundamental process internalizing molecules from the plasma membrane, endocytosis plays a crucial role in podocyte biology. Our previous study has identified that overexpression of Myole may enhance podocyte endocytosis. However, its potential mechanism has been not well understand. Thus, we aimed to analyze whether albumin endocytosis by mouse glomerular podocytes is dependent on Myo1e expression. Also, we aimed to elucidate whether the underlying mechanism is mediated by Dynamin. Methods Firstly, mouse podocyte cells (MPC5) were treated with different concentrations of FITC-bovine serum albumin (BSA). The fluorescence intensity and cell viability were detected by flow cytometry and MTT assays, respectively. Afterwards, the optimal concentration of FITC-BSA was determined. Secondly, MPC5 cells were treated with Myole overexpression or knockdown. Cell morphology was observed under microscope. Immunofluorescence assay was used to determine the expression of F-actin. The protein expression of nephrin and podocin was detected by western blot. Flow cytometry was used to detect MPC5 cell apoptosis with annexin V. Finally, MPC5 cells were treated with Myole overexpression and/or Dynasore (a GTPase inhibitor of Dynamin). The fluorescence intensity was detected using flow cytometry assay. Results MPC5 endocytosis BSA was elevated with a concentration-dependent manner. MTT results showed that MPC5 cell viability was inhibited with a concentration-dependent manner. Myo1e overexpression promoted podocyte endocytic FITC-BSA, which was contrary to its knockdown. Under microscope, after inhibition of Myo1e, podocyte foot process fusion was observed. Myo1e overexpression promoted the expression of cytoskeleton F-actin and podocyte-specific molecules (nephrin and podocin) in podocyte endocytic FITC-BSA. Furthermore, we found that Myo1e promoted the apoptosis of podocytes. Dynasore attenuated the increase in endocytosis of FITC-BSA induced by Myo1e overexpression, suggesting that podocytes might mediate albumin endocytosis via Myo1e-Dynamin-Albumin. Conclusion Our findings revealed that overexpression of Myo1e promotes albumin endocytosis in mouse glomerular podocyte endocytic albumin mediated by Dynamin.

Abstract
Parents can have profound effects on offspring fitness. Little, however, is known about the mechanisms through which parental genetic variation influences offspring physiology in natural systems. White-throated sparrows (Zonotrichia albicollis, WTSP) exist in two genetic morphs, tan and white, controlled by a large polymorphic supergene. Morphs mate disassortatively, resulting in two pair types: tan male × white female (T × W) pairs, which provide biparental care and white male × tan female (W × T) pairs, which provide female-biased care. To investigate how parental composition impacts offspring, we performed RNA-seq on whole blood of WTSP nestlings sampled from nests of both pair types. Parental pair type had a large effect on nestling gene expression, with 881 genes differentially expressed (DE) and seven correlated gene coexpression modules. The DE genes and modules expressed at higher levels in W × T nests with female-biased parental care function in metabolism and stress-related pathways resulting from the overrepresentation of proteolysis and stress-response genes (e.g., SOD2, NR3C1). These results show that parental genotypes and/or associated behaviours influence nestling physiology, and highlight avenues of further research investigating the ultimate implications for the maintenance of this polymorphism. Nestlings also exhibited morph-specific gene expression, with 92 differentially expressed genes, comprising immunity genes and genes encompassed by the supergene. Remarkably, we identified the same regulatory hub genes in these blood-derived expression networks as were previously identified in adult WTSP brains (EPM2A, BPNT1, TAF5L). These hub genes were located within the supergene, highlighting the importance of this gene complex in structuring regulatory networks across diverse tissues.

Abstract
Genetic variations in glucocorticoid-induced transcript 1 (GLCCI1) have been associated with the response to corticosteroid treatment. However, the associations of GLCCI1 polymorphisms or gene expression with the prognosis of asthma and pathophysiological factors related to steroid insensitivity remain unclear. We sought to investigate the associations of GLCCI1, nuclear factor (erythroid-derived 2)-like 2 (Nrf2), and histone deacetylase 2 (HDAC2) mRNA expression levels and the GLCCI1 rs37973 polymorphism with asthma severity and future exacerbation in patients with asthma. Subjects included 25 patients with severe asthma and 127 patients with nonsevere asthma. mRNA expression levels in peripheral blood mononuclear cells were measured and evaluated as predictors of severe asthma using receiver operating characteristic (ROC) analysis. The hazard ratios of the mRNA expression levels for time to first exacerbation in the 1-year follow-up period were calculated. GLCCI1, Nrf2, and HDAC2 mRNA expression levels were significantly lower in patients with severe asthma than in patients with nonsevere asthma and could predict severe asthma with an area under the ROC curve of 0.68, 0.71, and 0.65, respectively. In contrast, no relationship was found between the GLCCI1 rs37973 polymorphism and severe asthma. The hazard ratios for asthma exacerbation in patients with low GLCCI1, Nrf2, and HDAC2 mRNA expression levels were 3.24 (95% confidence interval, 1.42-7.40), 3.13 (1.37-7.16), and 2.98 (1.22-7.25), respectively. Patients with severe asthma could be distinguished by lower GLCCI1, Nrf2, and HDAC2 mRNA levels in peripheral blood cells, and all of these gene signatures could predict future asthma exacerbations.

Abstract
The present study aimed to ascertain the potential roles and mechanisms of action of micro (mi)RNA-22 in ischemic stroke. The results indicated that miRNA-22 expression was downregulated in ischemic stroke rats model, compared with a control group. The downregulation of miRNA-22 upregulated the expression of inflammatory factors [including tumor necrosis factor-α, interleukin (IL)-1β, IL-6 and IL-18]. It could also induce the expression of macrophage inflammatory protein (MIP-2), prostaglandin E2 (PGE2), cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS) in the in vitro model. By contrast, the overexpression of miRNA-22 downregulated the expression of inflammatory factors, and suppressed the expression of MIP-2, PGE2, COX-2 and iNOS in the in vitro model. The downregulation of miRNA-22 induced the protein expression of nuclear factor (NF)-κB and phosphorylated-p38 (p-p38) mitogen-activated protein kinase (MAPK) in the in vitro model. By comparison, the overexpression of miRNA-22 suppressed the protein expression of NF-κB and p-p38 in the in vitro model. Typically, LY2228820, the p38 inhibitor (3 nM) would mitigate the pro-inflammatory effects of anti-miRNA-22 in the in vitro model. These results suggested that miRNA-22 can alleviate ischemic stroke-induced inflammation in rats model or vitro model through p38 MAPK/NF-κB pathway suppression.

Abstract
Insulin functions as a regulator of metabolism and plays an important role in reproduction. Hyperinsulinemia is often observed in patients with obesity and diabetes type 2 and is known to impair fertility, but the underlying molecular mechanisms are only partly understood. Metabolic programming through epigenetic mechanisms such as DNA methylation during embryonic development can lead to health implications for the offspring later in life. Our aim was to study the potential effect of hyperinsulinemia on gene expression and DNA methylation of embryos by adding insulin (0.1 µg/ml = INS0.1 or 10 µg/ml = INS10) during in vitro oocyte maturation by using the EmbryoGENE DNA methylation array for a study of the bovine epigenome. Our results showed significant differences between blastocysts originating from insulin-treated oocytes compared with untreated control blastocysts. In total, 13,658 and 12,418 probes were differentially methylated (DM) in INS0.1 and INS10, respectively, with an overlap of 3,233 probes in the DM regions (DMR) for both insulin groups. Genes related to pathways such as lipid metabolism, growth and proliferation, mitochondrial function, and oxidative stress responses were influenced at both the epigenetic and transcriptomic levels. In addition, imprinted genes and genes with functions in the epigenetic machinery were among the DMRs. This study identified DMRs correlated to differential expression of genes involved in metabolic regulation and should help to improve our knowledge of the underlying molecular mechanisms of metabolic imbalance.

Abstract
Renal fibrosis participates in the progression of hypertension-induced kidney injury. The effect of SIRT3, a member of the NAD+-dependent deacetylase family, in hypertensive nephropathy remains unclear. In this study, we found that SIRT3 was reduced after angiotensin II (AngII) treatment both in vivo and in vitro. Furthermore, SIRT3-knockout mice aggravated hypertension-induced renal dysfunction and renal fibrosis via chronic AngII infusion (2000 ng/kg per minute for 42 days). On the contrary, SIRT3-overexpression mice attenuated AngII-induced kidney injury compared with wild-type mice. Remarkably, a co-localization of SIRT3 and KLF15, a kidney-enriched nuclear transcription factor, led to SIRT3 directly deacetylating KLF15, followed by decreased expression of fibronectin and collagen type IV in cultured MPC-5 podocytes. In addition, honokiol (HKL), a major bioactive compound isolated from Magnolia officinalis (Houpo), suppressed AngII-induced renal fibrosis through activating SIRT3-KLF15 signaling. Taken together, our findings implicate that a novel SIRT3-KLF15 signaling may prevent kidney injury from hypertension and HKL can act as a SIRT3-KLF15 signaling activator to protect against hypertensive nephropathy.

Abstract
BACKGROUND The lateral ganglionic eminence (LGE) in the ventral telencephalon is a diverse progenitor domain subdivided by distinct gene expression into a dorsal region (dLGE) that gives rise to olfactory bulb and amygdalar interneurons and a ventral region (vLGE) that gives rise to striatal projection neurons. The homeobox gene, Gsx2, is an enriched marker of the LGE and is expressed in a high dorsal to low ventral gradient in the ventricular zone (VZ) as development proceeds. Aside from Gsx2, markers restricted to the VZ in the dLGE and/or vLGE remain largely unknown. RESULTS Here, we show that the gene and protein expression of Glucocorticoid-induced transcript 1 (Glcci1) has a similar dorsal to ventral gradient of expression in the VZ as Gsx2. We found that Glcci1 gene and protein expression are reduced in Gsx2 mutants, and are increased in the cortex after early and late Gsx2 misexpression. Moreover, Glcci1 expressing cells are restricted to a subpopulation of Gsx2 positive cells on the basal side of the VZ and co-express Ascl1, but not the subventricular zone dLGE marker, Sp8. CONCLUSIONS These findings suggest that Glcci1 is a new marker of a subpopulation of LGE VZ progenitor cells in the Gsx2 lineage.

Abstract
This study aimed to elucidate the precise mechanisms underlying the protective effects of phosphoseryl-tRNA kinase (PSTK) against cisplatin-induced podocyte injury. PSTK overexpression and knockdown vectors were generated and transfected into murine podocyte cells-5. PSTK levels were measured, and transcriptome sequencing was conducted. Differential expression analysis was performed to identify messenger RNAs (mRNAs) that were positively and negatively correlated with PSTK. We selected 10 candidate genes identified via real-time quantitative polymerase chain reaction and Western blot analysis for further analysis. As expected, PSTK levels were significantly higher in PSTK-overexpressing podocytes and significantly lower in PSTK-knockdown podocytes. PSTK overexpression resulted in the upregulation of 122 genes and downregulation of 372 genes in podocytes. On the other hand, PSTK knockdown resulted in the upregulation of 231 genes and downregulation of 445 genes. Furthermore, the analysis revealed that 11 genes were positively correlated with PSTK, whereas 20 genes were negatively correlated with PSTK. The obtained PSTK-regulated genes were primarily involved in molecular function, biological process, and cellular component, as well as the angiogenesis pathway. The Wnt family member 10A levels were significantly higher after PSTK overexpression, but were significantly lower after PSTK knockdown. In addition, Na+/K+ ATPase subunit α-2 and matrix metalloproteinase 9 levels were significantly downregulated after PSTK overexpression, but significantly upregulated upon PSTK knockdown. Cell proliferation was significantly increased upon PSTK overexpression, but significantly decreased upon PSTK suppression. The results of this study not only identified several significant PSTK-regulated genes for further validation, but also provided insights into the mechanisms underlying the protective effects of PSTK on podocytes.
