  • Evaluation of the association of plasma pentraxin 3 levels with type 2 diabetes and diabetic nephropathy in a Malay population
  • 2013

    • Recent reports have demonstrated that elevated plasma long pentraxin 3 (PTX3) levels are associated with cardiovascular and chronic kidney diseases. In the current study, we investigated the plasma PTX3 levels in 296 Malay subjects including the subjects with normal glucose tolerance (NGT) and type 2 diabetes (T2DM) patients with or without DN by using an enzyme-linked immune-sorbent assay. Results showed that in males, plasma PTX3 levels in T2DM patients without DN were lower than that in the subjects with NGT (2.78 versus 3.98 ng/mL;P=0.021). Plasma PTX3 levels in T2DM patients with DN were decreased compared to the patients without DN (1.63 versus 2.78 ng/mL;P=0.013). In females, however, no significant alteration of plasma PTX3 levels among NGT subjects and T2DM patients with and without DN was detected. Furthermore, an inverse correlation between PTX3 and body mass index was found in male subjects with NGT (P=0.012;r=-0.390), but not in male T2DM patients, neither in all females. The current study provided the first evidence that decreased plasma PTX3 levels are associated with T2DM and DN in Malay men and also suggested that PTX3 may have different effects in DN and chronic kidney diseases.

  • Genetic and biological effects of sodium-chloride cotransporter (SLC12A3) in diabetic nephropathy
  • 2014
  • Ingår i: American journal of nephrology. - : S. Karger AG. - 1421-9670 .- 0250-8095. ; 40:5, s. 408-416
  • Tidskriftsartikel (refereegranskat)abstract
    • <b><i>Background/Aims:</i></b> Solute carrier family 12 member 3 (<i>SLC12A3</i>) encodes a sodium/chloride transporter in kidneys. Previous reports suggest that Arg913Gln polymorphism in this gene is associated with diabetic nephropathy (DN), but the data appear to be inconsistent. Up to now, there is no biological evidence concerning the effects of <i>SLC12A3</i> in DN. In this study, we aim to evaluate the genetic effects of the <i>SLC12A3 </i>gene and its Arg913Gln polymorphism with genetic and functional analyses. <b><i>Methods:</i></b> We genotyped <i>SLC12A3</i> genetic polymorphisms including Arg913Gln in 784 non-diabetes controls and 633 type 2 diabetes (T2D) subjects with or without DN in a Malaysian population and performed a meta-analysis of the present and previous studies. We further analyzed the role of <i>slc12a3</i> in kidney development and progress of DN in zebrafish and db/db mice. <b><i>Results:</i></b> We found that <i>SLC12A3</i> Arg913Gln polymorphism was associated with T2D (p = 0.028, OR = 0.772, 95% CI = 0.612-0.973) and DN (p = 0.038, OR = 0.547, 95% CI = 0.308-0.973) in the Malaysian cohort. The meta-analysis confirmed the protective effects of <i>SLC12A3</i> 913Gln allele in DN (Z-value = -1.992, p = 0.046, OR = 0.792). Furthermore, with knockdown of zebrafish ortholog, <i>slc12a3 </i>led to structural abnormality of kidney pronephric distal duct at 1-cell stage. <i>Slc12a3</i> mRNA and protein expression levels were upregulated in kidneys of db/db mice from 6, 12, and 26 weeks at the age. <b><i>Conclusion:</i></b> The present study provided the first biological and further genetic evidence that <i>SLC12A3</i> has genetic susceptibility in the development of DN, while the minor 913Gln allele in this gene confers a protective effect in the disease. i 2014 S.

  • Evaluation of Antidiabetic Effects of the Traditional Medicinal Plant Gynostemma pentaphyllum and the Possible Mechanisms of Insulin Release
  • 2015
  • Ingår i: Evidence-based complementary and alternative medicine : eCAM. - : Hindawi Limited. - 1741-427X .- 1741-4288. ; 2015, s. 120572-

    • Aims. To evaluate the antidiabetic effects ofGynostemma pentaphyllum(GP) in Goto-Kakizaki (GK) rat, an animal model of type 2 diabetes, and to investigate the mechanisms of insulin release.Methods. Oral glucose tolerance test was performed and plasma insulin levels were measured.Results. An oral treatment withGP(0.3 g/kg of body weight daily) for two weeks in GK rats improved glucose tolerance versus placebo group (P<0.01). Plasma insulin levels were significantly increased in theGP-treated group. The insulin release fromGP-treated GK rats was 1.9-fold higher as compared to the control group (P<0.001).GPstimulated insulin release in isolated GK rat islets at high glucose. Opening of ATP-sensitive potassium (K-ATP) channels by diazoxide and inhibition of calcium channels by nifedipine significantly decreased insulin response toGP. Furthermore, the protein kinase A (PKA) inhibitor H89 decreased the insulin response toGP(P<0.05). In addition,GP-induced insulin secretion was decreased after preincubation of GK islets with pertussis toxin to inhibit exocytoticGeproteins (P<0.05).Conclusion.The antidiabetic effect ofGPis associated with the stimulation of insulin release from the islets.GP-induced insulin release is partly mediated via K-ATP and L-type Ca2+channels, the PKA system and also dependent on pertussis toxin sensitiveGe-protein.

  • Antidiabetic Effect of Oral Borapetol B Compound, Isolated from the Plant Tinospora crispa, by Stimulating Insulin Release
  • 2013
  • Ingår i: Evidence-based complementary and alternative medicine : eCAM. - : Hindawi Limited. - 1741-427X .- 1741-4288. ; 2013, s. 727602-
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims. To evaluate the antidiabetic properties of borapetol B known as compound 1 (C1) isolated fromTinospora crispain normoglycemic control Wistar (W) and spontaneously type 2 diabetic Goto-Kakizaki (GK) rats.Methods. The effect of C1 on blood glucose and plasma insulin was assessed by an oral glucose tolerance test. The effect of C1 on insulin secretion was assessed by batch incubation and perifusion experiments using isolated pancreatic islets.Results. An acute oral administration of C1 improved blood glucose levels in treated versus placebo groups with areas under glucose curves 0–120 min being72±17versus344±10 mmol/L (P<0.001) and492±63versus862±55 mmol/L (P<0.01) in W and GK rats, respectively. Plasma insulin levels were increased by 2-fold in treated W and GK rats versus placebo group at 30 min (P<0.05). C1 dose-dependently increased insulin secretion from W and GK isolated islets at 3.3 mM and 16.7 mM glucose. The perifusions of isolated islets indicated that C1 did not cause leakage of insulin by damaging islet beta cells (P<0.001).Conclusion. This study provides evidence that borapetol B (C1) has antidiabetic properties mainly due to its stimulation of insulin release.

  • Diminishing benefits of urban living for children and adolescents' growth and development
  • 2023
  • Ingår i: Nature. - : Springer Science and Business Media LLC. - 1476-4687 .- 0028-0836. ; 615:7954, s. 874-883

    • Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.
