Growing evidence suggests that adipokines may be therapeutic targets for cardiometabolic diseases such as type 2 diabetes mellitus (T2DM). C1q TNF Related Protein 3 (CTRP3) is a newly discovered ...adipokine which shares properties with adiponectin. The literature about the association between circulating levels of CTRP3 and T2DM has been conflicting. The present study reassessed the data on circulating CTRP3 levels in T2DM patients compared to controls through a systematic review and meta-analysis.
A literature search was performed in Medline, Embase, Scopus, and Web of science to identify studies that measured circulating CTRP3 levels in T2DM patients and controls.
The search identified 124 studies of which 59 were screened for title and abstract and 13 were subsequently screened at the full text stage and 12 studies included into the meta-analysis. Subgroup analyses, depending on the presence of T2DM complications, matching for BMI, age, and cut off value of fasting blood sugar and HOMA-IR, were performed.
The results show that circulating CTRP3 levels are negatively associated with T2DM status (SMD: −0.837; 95% CI: (−1.656 to −0.017); p = 0.045). No publication bias was identified using the Begg’s rank correlation and Egger’s linear regression tests (P = 1 and P = 0.44, respectively). Meta-regression demonstrated significant association between CRTP3 levels with BMI (slope: 0.11; 95% CI: 0.04–0.19; p = 0.001) and sex (slope: −0.07; 95% CI: −0.12 to −0.01; p = 0.008).
The present systematic review and meta-analysis evidences a negative association between circulating level of CTRP3 and T2DM status. BMI and sex may modify this association.
Background & Objective: In traditional medicine, leaves of white mulberry (Morus alba L.) are used as antidiabetic agents. Considering the presence of flavonoids, this plant exhibits insulin mimetic ...activities. Nesfatin-1 is described as an anorexigenic regulatory peptide, which can influence glucose metabolism via insulin sensitivity enhancement. This study examined the effects of both mulberry leaf powder and extract (MLP and MLE) on fasting blood glucose (FBG), nesfatin-1, and insulin in diabetic Wistar rats. Materials & Methods: Five groups of rats (n, 40) were included and examined in this study. A group was selected as the healthy control (I), while the other groups received streptozotocin and nicotinamide (55 and 110 mg/kg bw, respectively) for diabetes induction. Diabetic rats were then grouped as follows: control group (II); sham group (receiving ethanol) (III); treatment group receiving 600 mg/kg/day of MLE (IV); and treatment group receiving 25% MLP (V). After 6 weeks, we measured insulin, nesfatin-1, and FBG in the groups. Results: The FBG level decreased in the treatment groups, while serum insulin increased in comparison with the diabetic controls. In addition, serum level of nesfatin-1 improved significantly (to an almost normal level) in MLP rats in comparison with the diabetic controls. (pvalue<0.05) The effects of MLE on serum nesfatin-1 was similar to MLP but not significant. (pvalue>0.05) Conclusion: Considering the reduction in insulin level and the rise in blood glucose, the diabetic control group showed an increase in serum nesfatin-1 with a compensatory mechanism, while hyperglycemia improved in the MLE and MLP groups, and the level of nesfatin-1 reduced. MLP showed greater efficacy than MLE in the improvement of nesfatin-1, which might be related to the presence of ethanol in MLE.
Abstract
Objective
Gestational diabetes mellitus (GDM) is closely related to obesity, adipose tissue, and adipokines. Adiponectin-homologous adipokines with anti-inflammatory properties, including ...C1q/TNF-related protein 3 (CTRP3) and CTRP9, regulate glucose and lipid metabolism, which was measured in pregnant women with GDM with the aim to assess their circulating levels and their relation with inflammatory cytokines and other biochemical data.
Methods
Serum levels of CTRP3, CTRP9, adiponectin, tumor necrosis factor (TNF)-α, and interleukin (IL)-6 were measured in 43 subjects with GDM and 42 healthy controls by enzyme-linked immunosorbent assay.
Results
Serum levels of adiponectin and CTRP3 were lower in GDM subjects than in controls, whereas CTRP9, TNF-α, and IL-6 showed higher concentrations in subjects with GDM than in controls. In the subjects with GDM, there was a significant association of CTRP3 with homeostasis model assessment of insulin resistance (HOMA-IR), body mass index, and triglycerides, whereas CTRP9 is associated with TNF-α and HOMA-IR.
Conclusion
The differences in the assessed levels of CTRP3 and CTRP9 suggest a possible relation with the pathogenesis of GDM, in particular insulin resistance, which showed significant association with both adipokines.
Background: NAFLD patients have higher risk of atherosclerosis cardiovascular disease (ASCVD). apo B/apoA-I ratio and atherogenic index of plasma (AIP) have been suggested as biomarker for ASCVD.
...Methods: apo A-I, apoB, aryl esterase (ARE) and paraoxonase (PON) activities and carotid intima media thickness (cIMT) were determined in 49 NAFLD patients and 33 controls.
Results: Plasma levels of apo A-I, adiponectin, ARE and PON activities decreased in NAFLD patients, while apo B, AIP and apoB/apo A-I ratio level were higher in NAFLD patients compared to controls. Furthermore, cIMT showed a positive association with AIP, apo B/apo A-I ratio and AIP + (apo B/apo A-I) in NAFLD patients. Strikingly, AIP + (apo B/apo A-I) showed a good ability to discriminating increased cIMT in NAFLD patients.
Conclusions: The result showed that AIP and apo B/apo A-I associated with cIMT in NAFLD patients; however, more study are needed to prove this concept.

Data concerning the association of serum levels of vitamin D and metalloproteinases and vitamin D receptor gene polymorphism with coronary artery disease (CAD) is not fully demonstrated. The present ...study aimed to evaluate the association of vitamin D receptor gene polymorphism, serum levels of 25(OH) vitamin D and metalloproteinase-9 (MMP-9) with CAD.
104 patients with CAD and 69 Non-CAD subjects were included in current study. Vitamin D receptor genotypes were determined by PCR-RFLP method. The 25(OH) vitamin D and MMP-9 were determined by ELISA assay.
There was a significant reduction of vitamin D in CAD patients (P=0.001). The metalloproteinase 9 levels of CAD patient was increased significantly compared with controls (P=0.001). A significant reverse correlation also was found between MMP-9 concentration and 25(OH) vitamin D levels of patients (r=−0.28, P<0.001). In addition, we identified that VDR gene FokI polymorphism was significantly associated with CAD. Furthermore, MMP-9 levels of CAD patients with ff genotype of FokI polymorphism was higher significantly than patients with FF and Ff genotypes. It has been also found that MMP-9 levels of CAD patients with ff genotype of FokI polymorphism was higher significantly than patients with FF and Ff genotypes.
Our results indicated that 25(OH) vitamin D, MMP-9 levels and VDR gene FokI polymorphisms play a critical role in the development and progression of CAD and may contribute to susceptibility to CAD in Iranian populations.
•Serum levels of 25(OH) vitamin D decrease in CAD patients.•Serum level of MMP-9 increase in CAD patients.•25(OH) vitamin D shows inverse correlation with MMP-9 in CAD patients.•VDR gene FokI polymorphism is associated with CAD.•MMP-9 levels associated with VDR gene FokI polymorphism.
Multiple sclerosis (MS) is a deleterious autoimmune and demyelinating disorder of the central nervous system with debilitating sensory and motor complications. There is still no definite cure for it ...and the main focus for its treatment mostly pivots around subsiding its severity and recurrence. Experimental autoimmune encephalomyelitis (EAE) is an established animal model of MS. S-allyl cysteine (SAC) is the active and main constituent of aged garlic extract with anti-inflammatory and neuroprotective property. This study was conducted to evaluate its possible protective effect in EAE model of MS. SAC was administered p.o. at a dose of 50 mg/kg/day to female C57BL/6 mice immunized with myelin oligodendrocytic glycoprotein (MOG35-55). Results showed that SAC is capable to alleviate clinical signs and severity of the disease and improved lumbar spinal cord tissue level of tumor necrosis factor α (TNFa), interleukin 17 (IL-17), activity-dependent neuroprotector homeobox (ADNP), microtubule-associated proteins 1A/1 B light chain 3A (MAP1LC3A), and matrix metalloproteinase 9 (MMP-9). In addition, SAC attenuated inflammatory cell infiltration, axonal demyelination, and axonal loss in lumbar spinal cord in EAE group, as demonstrated by H & E, Luxol fast blue (LFB), and Bielschowsky silver staining, respectively. Taken together, SAC could mitigate severity of MOG35-55-induced EAE as a valid model of MS via amelioration of pathogenic molecular mechanisms responsible for neuroinflammation and axonal damage.
•Klotho expression showed a significant reduction in coronary artery disease PBMCs.•Klotho serum levels were decreased significantly in atherosclerotic patients.•FOXO1 gene expression was increased ...in coronary artery disease PBMCs.•Klotho was a good Biomarker for diagnosis and differentiation of CAD from controls.
Atherosclerosis is one of the main reasons for adult mortality in advanced populations and countries with high stress levels. Klotho family are single-pass trans-membrane proteins that involve in the genesis and progression of various diseases, including acardiovascular disease, apoptosis and stress oxidative imbalance.
Present study, investigates the pattern of changes in Klotho and FOXO1 gene expressions and levels in atherosclerosis.
Present case control study consisted of 79 patients with atherosclerosis and 78 healthy controls. PBMC (peripheral mono-nuclear blood cells) expression levels of Klotho and FOXO1 were assayed, using qPCR method. Serum concentration of Klotho and FOXO1 were measured by ELISA method.
A significant reduction was found in PBMC genes expression levels of Klotho (P < 0.01) of patients as comparison with controls. PBMC Gene expression of FOXO1 in patients was increased significantly (P < 0.01) when compared with controls. Pearson analysis showed a positive correlation between PBMC Klotho gene expression and Klotho levels of patients (P < 0.01). The correlation between serum concentrations of Klotho and FOXO1 of patients was also positive significantly (P < 0.01). AUC of ROC for gene expression and serum concentration of Klotho in patients were 0.701 and 0.737 respectively.
Investigating the PBMC gene expression and serum concentration of Klotho in patients with atherosclerosis is suggested could be a convenient novel biomarker for predicting, prognosis, monitoring the disease progression and designing a suitable drug for patients with atherosclerosis.
It has recently found that adipokines, play a numerous functional roles in inflammation, lipids and glucose metabolism and in the pathogenically conditions such as atherosclerosis and insulin ...resistance. Therefore, for the first time we aimed the present study to evaluating serum levels of CTRP5 and inflammatory cytokines patients with CAD and T2DM in comparison with controls.
This study was done on 44 patients with CAD, 45 type 2 diabetes mellitus (T2DM), 41 CAD + T2DM and 41 controls. Serum levels of TNF-α, IL-6, MCP-1 and CTRP5 were investigated by ELISA method.
The CTRP5 levels of all patients groups were lower in comparison with control group. There was a significant negative relationship between CTRP5 levels and cytokines concentration in the studied patients.
Our findings suggested a potential role of CTRP5 in inflammatory process of underlying atherosclerosis and diabetes; however, more studies are needed to support these finding.

The present study was designed to evaluate the effects of resveratrol, atorvastatin, and a combination of resveratrol and atorvastatin on expression levels of genes involved in the cholesterol ...metabolic pathway in the fatty liver of C57/BL6 mice. A high-fat diet was used to induce fatty liver in C57/BL6 mice treated with resveratrol, atorvastatin, or a combination of resveratrol and atorvastatin. Pathological and biochemical studies were performed. In addition, hepatic gene expressions of ATP-binding cassette transporter A1 (
),
, liver X receptor (
)α, scavenger receptor B1 (
), low-density lipoprotein receptor (
), and miR33 were evaluated by the real-time PCR method, and the Western blot method was used to measure the ABCA1, ABCG1, and LXRα protein levels. Resveratrol and atorvastatin reduced fat accumulation in the liver of mice with fatty liver, and this effect was correlated with decreased blood glucose levels, triglyceride, cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol blood levels compared with the positive control (PC) group. In contrast to the animals of the PC group, fatty liver groups that received resveratrol and atorvastatin had a significant effect on the mRNA levels of the

α,
,
, and miR33 genes. Moreover, resveratrol and atorvastatin administration elevated ABCA1 and ABCG1 and reduced LXRα protein expression. Obtained results showed that resveratrol and atorvastatin combination therapy can improve nonalcoholic fatty liver disease by targeting genes involved in cholesterol metabolism and miR33.
Type 2 diabetes (T2D) is accompanied by elevated inflammation, oxidative stress, hyperlipidemia and hyperglycemia which all contribute to cardiovascular disease pathogenesis. Saffron as a ...complementary medicine and source of antioxidants could play a role in alleviating diabetes and its complications. The aim of this study was to determine the effects of saffron supplementation as an adjunct therapy in T2D.
This randomized controlled trial included 80 T2D patients with a mean age of 54.1 years. Participants were randomly assigned into two groups to take either saffron tablets (100 mg/day; n=40) or placebo (n=40) for 12 weeks. Fasting blood samples were obtained at the beginning and after the intervention period to quantify glycemic factors, lipid profile, and biomarkers of inflammation and oxidative stress. Anthropometric indices and dietary intakes were also measured at baseline and at study end.
Compared with placebo, saffron supplementation resulted in significant decreases in waist circumference (
<0.001) and malondialdehyde (MDA) (
=0.001). There was no statistically significant difference in other indices, including anthropometric parameters, serum insulin, fasting blood glucose, HbA1c, insulin sensitivity indices, lipid profile, high-sensitivity C-reactive protein, total antioxidant capacity, and tumor necrosis factor-α between the study groups (
>0.05).
Overall, 12 weeks of saffron supplementation in diabetic patients had beneficial effects on waist circumference and serum MDA levels. However, saffron did not influence other evaluated cardio metabolic risk markers in diabetic patients.
