AIM: The Xiaoke Pill containing Chinese herb extracts and Glibenclamide, is used in therapy for type 2 diabetes mellitus (T2DM), and is effective in reducing the risk of hypoglycemia and improving diabetes symptoms compared with Glibenclamide. We describe a quantitative proteomics project to measure the T2DM serum proteome response to the Xiaoke Pill and Glibenclamide. METHODS: Based on a recently conducted 48-week clinical trial comparing the safety and efficacy of Glibenclamide (n = 400) and Xiaoke Pill (n = 400), after matching for age, sex, BMI, drug dose and whether hypoglycemia occurred, 32 patients were selected for the serum based proteomic analysis and divided into four groups (with/without hypoglycemia treated with Xiaoke Pill or Glibenclamide, n = 8 for each group)...

BACKGROUND/AIMS: The sulphonylurea glibenclamide (Gli) is widely used in the treatment of type 2 diabetes. In addition to its antidiabetic effects, low incidences of certain types of cancer have been observed in Gli-treated diabetic patients. However, the mechanisms underlying this observation remain unclear. The aim of the present work was to evaluate whether obese adult rats that were chronically treated with an antidiabetic drug, glibenclamide, exhibit resistance to rodent breast carcinoma growth...

Xinrui Wang, Robert H Fitts
Regular exercise-training is known to affect the action potential duration (APD) and improve heart function, but the involvement by β-adrenergic receptor (β-AR) subtypes and/or KATP channel is unknown. To address this, female and male Sprague-Dawley rats were randomly assigned to voluntary wheel running or control groups and after 6-8 weeks training anesthetized and myocytes isolated. Exercise-training significantly increased APD of apex and base myocytes at 1Hz, while decreasing the APD at 10Hz. Ca(2+) transient durations reflected the changes observed in APD, while Ca(2+) transient amplitudes were unaffected by wheel running...

Carvedilol, a drug available as a racemic mixture, is eliminated as hydroxyphenylcarvedilol (OHC) by CYP2D6 and O-desmethylcarvedilol (DMC) by CYP2C9 followed by conjugation to glucuronides. In contrast to other β-adrenergic receptor antagonists, carvedilol does not induce insulin resistance or worsen glycaemic control in the diabetic hypertensive patients. This study aims to investigate the implications of type 2 diabetes (T2DM) on the pharmacokinetics of carvedilol enantiomers using an integrated population pharmacokinetic modelling approach...

The noninvasive measurement of functional β-cell mass would be clinically valuable for monitoring the progression of type 1 and type 2 diabetes, as well as the viability of transplanted insulin-producing cells. Although previous work employing magnetic resonance imaging has shown promise for functional β-cell mass determination through voltage-dependent Ca(2+) channel (VDCC)-mediated internalization of Mn(2+), the clinical utility of this technique is limited by the cytotoxic levels of Mn(2+) contrast agent...

To investigate the role of ATP-sensitive K(+) (KATP) channels on pacemaker activity in interstitial cells of Cajal (ICC), whole-cell patch clamping, RT-PCR, and intracellular Ca(2+) ([Ca(2+)]i) imaging were performed in cultured colonic ICC. Pinacidil (a K(+) channel opener) hyperpolarized the membrane and inhibited the generation of pacemaker potential, and this effect was reversed by glibenclamide (a KATP channel blocker). RT-PCR showed that Kir 6.1 and SUR2B were expressed in Ano-1 positive colonic ICC. Glibenclamide depolarized the membrane and increased pacemaker potential frequency...

Intracellular chloride concentration ([Cl(-)]i) in pancreatic β-cells is kept above electrochemical equilibrium due to the predominant functional presence of Cl(-) loaders such as the Na(+)K(+)2Cl(-) co-transporter 1 (Slc12a2) over Cl(-)extruders of unidentified nature. Using molecular cloning, RT-PCR, Western blotting, immunolocalization and in vitro functional assays, we establish that the "neuron-specific" K(+)Cl(-) co-transporter 2 (KCC2, Slc12a5) is expressed in several endocrine cells of the pancreatic islet, including glucagon secreting α-cells, but particularly in insulin-secreting β-cells, where we provide evidence for its role in the insulin secretory response...

Cardiac ATP-sensitive K(+) (KATP) channel activity plays an important cardio-protective role in regulating excitability in response to metabolic stress. Evidence suggests that these channels are also mechano-sensitive and therefore may couple KATP channel activity to increased cardiac workloads. However, the molecular mechanism that couples membrane stretch to channel activity is not currently known. We hypothesized that membrane stretch may alter the intrinsic MgATPase activity of the cardiac KATP channel resulting in increased channel activation...

Sulfonylureas are widely used class of drugs for the treatment of type 2 diabetes (T2DM). Recent research has demonstrated that SLCO1B3 functions as a determinant of the insulinotropic effect of glibenclamide at the tissue level. However, whether this gene can influence the efficacy of glibenclamide in type 2 diabetic patients is not currently well-understood. All of our study subjects were enrolled from the Xiaoke Pills Clinical Trial. The subjects were treated with glibenclamide, and followed for 48 weeks...

AIMS: Heart failure (HF) is frequent in type 2 diabetes (T2D) and several glucose-lowering medications may increase HF risk. In the SAVOR-TIMI trial, patients on Saxagliptin experienced a 27% higher risk of hospitalisation for HF (HHF). In a retrospective study on 127,555 patients, we showed that DPP-4i therapy was associated with a lower HHF risk than sulphonylurea (SU) therapy. We herein re-analyzed such data to evaluate intraclass differences among DPP-4i and SU. MATERIALS AND METHODS: We included T2D patients initiating DPP-4i or SU alone or in combination with metformin...
