Abstract Background Protein phosphatase 4 regulatory subunit 1 (PP4R1) is one of the regulatory subunits of PP4. It has been determined to be involved in the regulation of TNF-α-induced hepatic insulin resistance and gluconeogenesis. Considering the important role of PP4R1 in hepatic insulin resistance, the current study explored the expression and diagnostic value of PP4R1 in type 2 diabetes mellitus (T2DM) patients and further investigated its predictive value for the development of chronic complications. Method Hundred and five patients with T2DM and 97 healthy controls were collected. qRT-PCR was used for the measurement of serum PP4R1 mRNA level in both T2DM and control groups. The diagnostic value of PP4R1 in T2DM patients was evaluated using receiver operating characteristic (ROC) curve. Kaplan-Meier methods and Cox regression analysis were used to evaluate the predictive value of PP4R1 for the development of chronic complications in T2DM patients. Results PP4R1 was determined to be elevated in the serum of T2DM patients compared with healthy controls. Serum PP4R1 had the potential to distinguish T2DM patients from healthy controls with a sensitivity of 81.9% and specificity of 82.5%. Patients with high PP4R1 expression experienced more chronic complications events. The multivariate Cox analysis results suggested that serum PP4R1 expression was an independent factor for the occurrence of chronic complications for T2DM patients.  Conclusion PP4R1 is elevated in the serum of T2DM patients, had the potential to distinguish T2DM patients from healthy controls. PP4R1 serves as a promising biomarker for predicting the risk of future chronic complications in T2DM patients.

Abstract Background Type 2 diabetes mellitus (T2DM) affects the social economy and quality of life, and has become a major threat to human health. This observation aimed to study the possibility of serum HOTAIR as a diagnostic index in patients with T2DM and to explore the prognostic potential of HOTAIR in the development of T2DM. Methods The expression of HOTAIR in serum of 96 patients with T2DM and 82 healthy controls was detected by the qRT-PCR technique. The related biochemical indexes of all participants were determined, such as total cholesterol (TC) and fasting blood glucose (FBG). The value of serum HOTAIR in the diagnosis of T2DM in the two groups was analyzed by the ROC curve. Moreover, the prognostic value of HOTAIR on T2DM was examined by the K-M curve and COX multivariate analysis. Results The results of the qRT-PCR analysis showed that the serum level of HOTAIR in patients with T2DM was significantly higher than that in healthy controls. ROC analysis showed that HOTAIR in serum was a diagnostic factor of T2DM. Further multivariate analysis showed that HOTAIR could be an independent biomarker in the prediction of chronic complications for T2DM patients, such as diabetic retinopathy and diabetic nephropathy. Conclusions We found the augment of HOTAIR expression was a character of T2DM. The high expression of serum HOTAIR was a potential non-invasive diagnostic marker and independent prognostic factor in patients with T2DM.

Background: Type 2 diabetes mellitus is a chronic metabolic disorder due to insulin resistance caused by destruction of beta cells of pancreas. Insulin resistance in newly diagnosed type 2 diabetes mellitus patients leads to hyperglycemia. Serum amylase and lipase levels is an exocrine enzyme produced by acinar cells of pancreas. Altered levels of serum amylase and lipase leads to endocrine disorders, metabolic syndrome and diabetes mellitus.Methods: This is a case-control study conducted in Akash Institute of Medical Sciences, A total 100 subjects (50 cases and 50 controls). All the subjects included after informed consent, blood samples are collected from the all the subjects. The serum amylase and was estimated by using enzymatic commercial available kits and fasting blood sugar (FBS), post-parandial blood sugar (PPBS), renal function test (RFT) and liver function test (LFT) was also estimated by laboratory standard methods.Results: This study evaluated the FBS, PPBS, RFT, LFT, Amylase and Lipase levels in patients with newly diagnosed type 2 diabetes mellitus patients and compare them with healthy controls. The serum amylase and lipase levels more significantly elevated in newly diagnosed type 2 diabetes mellitus patients and compared with the healthy controls. The study also found that significantly elevated levels of FBS, PPBS, RFT and LFT in newly diagnosed type 2 diabetes mellitus patients and compared with the healthy controls, The statistically significant levels of serum amylase and lipase levels in patients with newly diagnosed type 2 diabetes mellitus when compared with the controls (p=0.0001).Conclusions: The study suggesting that to estimation of serum amylase and lipase levels in newly diagnosed type 2 diabetes mellitus patients useful for early detection of diabetes mellitus and its complications. Because elevated levels of serum amylase and lipase in patients with newly diagnosed type 2 diabetes mellitus, these levels are positively correlated with the FBS and PPBS.

AbstractGenome-wide association studies have identified more than 300 loci associated with type 2 diabetes mellitus; however, the mechanisms underlying their role in type 2 diabetes mellitus susceptibility remain largely unknown. Zinc finger AN1-type domain 3 (ZFAND3), known as testis-expressed sequence 27, is a type 2 diabetes mellitus-susceptibility gene. Limited information is available regarding the physiological role of ZFAND3 in vivo. This study aimed to investigate the association between ZFAND3 and type 2 diabetes mellitus. ZFAND3 was significantly upregulated in the liver of diabetic mice compared to wild-type mice. To overexpress ZFAND3, we generated a ZFAND3-expressing adenovirus (Ad) vector using an improved Ad vector exhibiting significantly lower hepatotoxicity (Ad-ZFAND3). Glucose tolerance was significantly improved in Ad-ZFAND3-treated mice compared to the control Ad-treated mice. ZFAND3 overexpression in the mouse liver also improved insulin resistance. Furthermore, gluconeogenic gene expression was significantly lower in primary mouse hepatocytes transduced with Ad-ZFAND3 than those transduced with the control Ad vector. The present results suggest that ZFAND3 improves glucose tolerance by improving insulin resistance and suppressing gluconeogenesis, serving as a potential novel therapeutic target for type 2 diabetes mellitus.

Background: Type 2 diabetes mellitus (T2DM) is an ever-growing epidemic in India, and poses significant morbidity, mortality, and socioeconomic burden. Introduction: Growth differentiation factor-15 (GDF15) is a stress-responsive cytokine, increased in T2DM patients compared to control subjects without the disease. We aimed to assess whether serum GDF15 and adipose tissue GDF15 expression can differentiate between obese pre-diabetes and T2DM and control populations. Methodology: We recruited 156 individuals including 73 type 2 diabetes, 30 pre-diabetes, and 53 healthy controls. Clinical history, anthropometric measurements and biochemical profiling were done. Insulin resistance indices were calculated following HOMA models. Serum GDF15 was measured by sandwich ELISA. Visceral adipose tissue (VAT) expression of GDF15 was observed in 17 T2DM patients and 29 controls using SYBR Green chemistry in RT-PCR using GAPDH as housekeeping gene. The data were analyzed on R programming platform using RStudio. Results: Serum GDF15 was significantly higher (p<0.001) in T2DM subjects (median 1445.47 pg/mL) compared to prediabetes (627.85 pg/mL) and healthy controls (609.01 pg/mL). Using the ΔΔCt method, the VAT GDF15 expression was 1.54 fold and 1.57 fold upregulated in T2DM (n=17) compared to control subjects (n=29), and obese (n=12) compared to non-obese (n=34)subjects, respectively. The optimal cut-off point following the Youden’s index method was found to be 868.09 pg/mL. ROC curve analysis revealed that serum GDF15 had a sensitivity, specificity, and area under the curve (AUC) of 90.41%, 79.52%, and 0.892 respectively. GDF15 levels were significantly associated with age, BMI, HbA1c, fasting blood sugar, and insulin resistance indices. Conclusion: Hence, serum GDF15 is a biomarker for T2DM patients in our study population from Western India. However, larger prospective cohorts are necessary to validate this claim.
