Epidemiological studies have demonstrated a close association of type 2 diabetes and hepatocellular carcinoma (HCC). Exenatide (Ex-4), a potent diabetes drug targeting glucagon-like peptide-1 receptor (GLP-1R), is protective against non-alcoholic fatty liver disease (NAFLD). However, the Ex-4 function and GLP-1R status have yet been explored in HCC. Herein we investigated the effect of Ex-4 in diethylnitrosamine (DEN)-treated mice consuming control or high-fat high-carbohydrate diet. Administration of Ex-4 significantly improved obesity-induced hyperglycemia and hyperlipidemia and reduced HCC multiplicity in obese DEN-treated mice, in which suppressed proliferation and induced apoptosis were confined to tumor cells...

AIM: Glucagon-like peptide-1 (GLP-1) receptor agonists are a kind of very popular antidiabetes drugs. They promote cell proliferation and survival through activation of signaling pathways in human islet cells involving phosphate idylinositol 3 kinase (PI3K) and extracellular regulated kinases 1 and 2 (ERK1/2), which are frequently activated in human colon cancer cells. Then, it is possible that taking GLP-1 receptor (GLP-1R) agonists persistently would induce proliferation of β cells as well as colon cancer cells...

Although amyloid β protein (Aβ) has been recognized as one of the main pathological characteristics in the brain of Alzheimer's disease (AD), the effective strategies against Aβ neurotoxicity are still deficient up to now. Glucagon-like peptide 1 (GLP-1), a natural gut hormone, was found to be effective in modulating insulin signaling and neural protection, but short half-life limited its clinical application in AD treatment. CJC-1131, a newly designed GLP-1 analogue with very longer half-life, has shown good effectiveness in the treatment of type 2 diabetes mellitus (T2DM)...

BACKGROUND: The effect of lixisenatide - a prandial once-daily glucagon-like peptide-1 receptor agonist - on glycaemic control in patients with inadequately controlled type 2 diabetes (T2DM), stratified by baseline β-cell function was assessed. METHODS: The 24-week GetGoal-M, -P and -S trials evaluated the efficacy and safety of lixisenatide in combination with oral antidiabetic agents. This post hoc analysis used data from patients receiving lixisenatide in these trials, divided into matched cohorts by propensity scoring and stratified according to baseline homeostasis model assessment of β-cell function (HOMA-β) index levels (high HOMA-β: > median HOMA-β [28...

Some modified glucagon-like-peptide-1 (GLP-1) analogs are highly important for treating type 2 diabetes. Here we investigated whether GLP-1 analogs expressed in Lactococcus lactis could be substrates for modification and export by the nisin dehydratase and transporter enzyme. Subsequently we introduced a lysinoalanine by coupling a formed dehydroalanine with a lysine and investigated the structure and activity of the formed lysinoalanine-bridged GLP-1 analog. Our data show: i) GLP-1 fused to the nisin leader peptide is very well exported via the nisin transporter NisT, ii) production of leader-GLP-1 via NisT is higher than via the SEC system, iii) leader-GLP-1 exported via NisT was more efficiently dehydrated by the nisin dehydratase NisB than when exported via the SEC system, iv) individual serines and threonines in GLP-1 are dehydrated by NisB to a significantly different extent, v) an introduced Ser30 is well dehydrated and can be coupled to Lys34 to form a lysinoalanine-bridged GLP-1 analog, vi) a lysinoalanine(30-34) variant's conformation shifts in the presence of 25% trifluoroethanol towards a higher alpha helix content than observed for wild type GLP-1 under identical condition, vii) a lysinoalanine(30-34) GLP-1 variant has retained significant activity...

Recent studies discussed the benefit of bariatric surgery on obese patients diagnosed with type 2 diabetes mellitus (T2DM). Several factors play an essential role in predicting the impact of bariatric surgery on T2DM, such as ABCD score (age, BMI, C-peptide, and duration of the disease), HbA1c, and fasting blood glucose, incretins [glucagon-like peptide-1 (GLP-1) and gastric inhibitory peptide (GIP)]. DiaRem score known to include factors such as age, HbA1c, medication, and insulin usage used to predict the remission of T2DM, but it has some limitations...

Type 2 diabetes (T2D) is characterized by a gradual decline of pancreatic beta cell function that determines the progressive course of the disease. While beta-cell failure is an important contributor to hyperglycemia, chronic hyperglycemia itself is also detrimental for beta-cell function, likely by inducing prolonged secretory stress on the beta cell as well as through direct glucotoxic mechanisms that have not been fully defined. For years, research has been carried out in search of therapies targeting hyperglycemia that preserve long-term beta-cell function in T2D, a quest that is still ongoing...

Nuclear medicine plays a pivotal role in the management of patients affected by neuroendocrine neoplasms (NENs). Radiolabeled somatostatin receptor analogs are by far the most advanced radiopharmaceuticals for diagnosis and therapy (radiotheranostics) of NENs. Their clinical success emerged receptor-targeted radiolabeled peptides as an important class of radiopharmaceuticals and it paved the way for the investigation of other radioligand-receptor systems. Besides the somatostatin receptors (sstr), other receptors have also been linked to NENs and quite a number of potential radiolabeled peptides have been derived from them...

The European Society for Clinical Nutrition has published recommendations on the "definition and classification of intestinal failure (IF)". Two criteria must be present: a "decreased absorption of macronutrients and/or water and electrolytes due to a loss of gut function" and the "need for parenteral support". Home parenteral support (HPS) is the primary treatment for chronic IF but is associated with complications. Areas covered: The principal cause of chronic IF is short bowel syndrome (SBS). The aim of treatment is to maximize intestinal absorption and reduce or eliminate the need for HPS to achieve the best possible quality of life...

Worldwide, an estimated 200 million people have chronic kidney disease (CKD), whose most common causes include hypertension, arteriosclerosis, and diabetes. About 40% of patients with diabetes develop CKD and intensive blood glucose control through pharmacological intervention can delay CKD progression. Standard therapies for the treatment of type 2 diabetes mellitus include metformin, sulfonylureas, meglitinides, thiazolidinediones, and insulin. While these drugs have an important role in the management of type 2 diabetes, only the thiazolidinedione pioglitazone can be used across the spectrum of CKD (stages 2-5) and without dose adjustment...

In this paper, we review the results of large, double-blind, placebo-controlled randomized trials mandated by the US Food and Drug Administration to examine the cardiovascular safety of newly-approved antihyperglycemic agents in patients with type 2 diabetes. The cardiovascular effects of dipeptidyl peptidase-4 (DPP-4) inhibitors remain controversial: while these drugs did not reduce or increase the risk of primary, pre-specified composite cardiovascular outcomes, one DPP-4 inhibitor (saxagliptin) increased the risk of hospitalization for heart failure in the overall population; another (alogliptin) demonstrated inconsistent effects on heart failure hospitalization across subgroups of patients, and a third (sitagliptin) demonstrated no effect on heart failure...

Long-term exposure to a high-fat diet (HFD) causes glucotoxicity and lipotoxicity in islet β cells and leads to the development of metabolic dysfunctions. Reductions in pancreatic and duodenal homeobox-1 (PDX-1) expression have been shown to induce type 2 diabetes mellitus by causing impairments to islet β cells. Glucagon-like peptide 1 (GLP-1) treatment reduces endogenous insulin resistance in HFD-induced type 2 diabetes mellitus. In the present study, the underlying mechanism by which GLP-1 exerts its function in type 2 diabetes mellitus was investigated...

Recently, cardiovascular outcome trials with glucose-lowering drugs used in type 2 diabetes mellitus, namely glucagon-like peptide-1 receptor agonists (GLP-1RA), liraglutide and semaglutide, showed a reduction in cardiovascular events, which had not been observed in trials with other incretin-based drugs, such as lixisenatide or with dipeptidyl peptidase-4 inhibitors (DPP4i). Mechanisms underlying the observed cardiovascular differences between DPP4i and GLP1-RA, and across individual GLP1-RA are poorly understood...
