Effects of naringenin on renal expression of organic cation transporter 1 and 2 proteins and metformin disposition in diabetic rats

Publication date: August 2019Source: Journal of Functional Foods, Volume 59Author(s): Edith Pascale Mofo Mato, M. Faadiel Essop, Peter Mark Oroma OwiraAbstractModulation of metformin transporters could affect its pharmacokinetics/pharmacodynamics. The effects of naringenin on the renal tubular Organic Cation Transporter 1 (OCT1) and 2 (OCT2) protein expressions and subsequently the metformin clearance in diabetic rats are hereby investigated. Male Sprague Dawley rats were divided into 7 groups. Animals were daily treated orally with metformin (250 mg/kg) or naringenin (60 mg/kg) alone or both for 56 days. Blood glucose tests were done. Serum, urine, and kidney samples were collected. Naringenin alone or in combination with metformin significantly increased creatinine clearance and lowered plasma metformin concentrations in diabetic rats compared to controls. OCT1 and OCT2 protein expressions in renal tissues were unchanged in diabetic rats treated with either naringenin or metformin, respectively. However, co-administration of metformin and naringenin upregulated OCT2 expression in diabetic rats. Naringenin may stimulate renal uptake/excretion of metformin by increasing OCT2 protein expression which facilitates metformin clearance in diabetic rats.Graphical abstractIllustration of the effect of naringenin on renal tubular cation transporters OCT1 and OCT2 Naringenin is the major flavonone in citrus fruits. It might increase renal organic cations transporters expression ...

Authors: Siamashvili M, Davis S Abstract INTRODUCTION: Bromocriptine mesylate quick release (QR) is a dopamine D2 receptor agonist and is the only oral, primarily centrally acting drug that can be used for the treatment of adults with type 2 diabetes. AREAS COVERED: The authors describe current recommendations on the use of bromocriptine mesylate QR. Major efficacy and safety parameters of the late phase trials, including The Cycloset Safety Trial, have been identified and presented. EXPERT OPINION: Efficacy of bromocriptine mesylate QR monotherapy appears to be low but is compensated by favorable safety pr...

CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]

Authors: Chung W, Promrat K, Wands J Abstract Diabetes mellitus (DM) negatively affects the development and progression of chronic liver diseases (CLD) of various etiologies. Concurrent DM and CLD are also associated with worse clinical outcomes with respect to mortality, the occurrence of hepatic decompensation, and the development of hepatocellular carcinoma (HCC). Unfortunately, early diagnosis and optimal treatment of DM can be challenging, due to the lack of established clinical guidelines as well as the medical complexity of this patient population. We conducted an exploratory review of relevant literature to...

Authors: Frías JP Abstract INTRODUCTION: The glucagon-like peptide-1 (GLP-1) receptor agonists (RA) have increasingly gained prominence in the treatment of type 2 diabetes (T2D) based on their glycemic benefits and favorable body weight and cardiorenal effects. Despite this, continued development of therapeutics with superior efficacy is important to help address persistent challenges in the attainment of metabolic goals in many patients with T2D. AREAS COVERED: Tirzepatide is an unimolecular dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA in development for the treatment of T2D. This re...

We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN. PMID: 33028760 [PubMed - in process]

Abstract Background: The clock drawing test (CDT) is frequently used to detect changes in cognition. Multiple scales of varying length have been published to assess performance. The aim of this study is to compare the CDT performance measured by three scales among a sample of nondemented patients on renal dialysis and identify the variables that affect performance. Methodology. This is a cross-sectional study performed at the dialysis unit at King Saud University Medical City. Eighty-nine dialysis patients performed the CDT. The CDT was scored by the methods of Rouleau et al. (RCS 10-point), Babins et al. (BCS 18-...
