ABSTRACT Diabetes Mellitus is a metabolic disorder that is characterized by high blood glucose because of the insulin-resistance and insulin-deficiency in Type 2,while the insulin deficiency due to destruction of islet cells in the pancreas in Type 1 . The development of type 2 diabetes is caused by a combination of lifestyle and genetic factors. Aging patients with diabetes are at increased risk of developing cognitive and memory dysfunctions,which is one of the significant symptoms of Alzheimer Disease(AD). Also, over 2/3 of AD patients were clinically indentified with impairment of glucose. Cognitive dysfunction would be associated with poor self-care ability in diabetes patients.This review will briefly summarize the current knowledge of the pathogenesis of these two diseases and highlight similarities in their pathophysiologies .Furthermore, we will shortly discuss recent progress in the insulin-targeted strategy, aiming to explore the inner linkage between these two diseases in aging populations.

    ABSTRACT: Organisms have evolved to survive rigorous environments and are not prepared to thrive in a world of caloric excess and sedentary behavior. A realization that physical exercise (or lack of it) plays a pivotal role in both the pathogenesis and therapy of type 2 diabetes mellitus (t2DM) has led to the provocative concept of therapeutic exercise mimetics. A decade ago, we attempted to simulate the beneficial effects of exercise by treating t2DM patients with 3 weeks of daily hyperthermia, induced by hot tub immersion. The short-term intervention had remarkable success, with a 1 % drop in HbA1, a trend toward weight loss, and improvement in diabetic neuropathic symptoms. An explanation for the beneficial effects of exercise and hyperthermia centers upon their ability to induce the cellular stress response (the heat shock response) and restore cellular homeostasis. Impaired stress response precedes major metabolic defects associated with t2DM and may be a near seminal event in the pathogenesis of the disease, tipping the balance from health into disease. Heat shock protein inducers share metabolic pathways associated with exercise with activation of AMPK, PGC1-a, and sirtuins. Diabetic therapies that induce the stress response, whether via heat, bioactive compounds, or genetic manipulation, improve or prevent all of the morbidities and comorbidities associated with the disease. The agents reduce insulin resistance, inflammatory cytokines, visceral adiposity, and body weight while increasing mitochondrial activity, normalizing membrane structure and lipid composition, and preserving organ function. Therapies restoring the stress response can re-tip the balance from disease into health and address the multifaceted defects associated with the disease.

    ABSTRACT: Diabetes mellitus (DM) is considered a risk factor for the development of Alzheimer disease (AD); however, how DM favors evolution of AD is still insufficiently understood. Hyperglycemia in DM is associated to an increase in mitochondrial reactive oxygen species (ROS) generation, as well as damage of hippocampal cells, reflected by changes in morphological and mitochondrial functionality. Similar mitochondrial damage has been observed when amyloid beta (Aβ) accumulates in the brain of AD patients. In DM, the excess of glucose in the brain induces higher activity of the hexosamine biosynthesis pathway (HBP), it synthesizes UDP-N-acetylglucosamine (UDP-GlcNAc), which is used by O-linked N-acetylglucosamine transferase (OGT) to catalyze O-GlcNAcylation of numerous proteins. Although O-GlcNAcylation plays an important role in maintaining structure and cellular functionality, chronic activity of this pathway has been associated with insulin resistance and hyperglycemia-induced glucose toxicity. Three different forms of OGT are known: nucleocytoplasmic (ncOGT), short (sOGT), and mitochondrial (mOGT). Previous reports showed that overexpression of ncOGT is not toxic to the cell; in contrast, overexpression of mOGT is associated with cellular apoptosis. In this work, we suggest that hyperglycemia in the diabetic patient could induce greater expression and activity of mOGT, modifying the structure and functionality of mitochondria in hippocampal cells, accelerating neuronal damage, and favoring the start of AD. In consequence, mOGT activity could be a key point for AD development in patients with DM.

    ABSTRACT: Brain insulin resistance is related to both diabetes and Alzheimer's disease. We investigated whether both chungkookjangs, soybeans fermented in a traditional method (TFC) and with Bacillus lichenifomis (SFC), can protect against cognitive dysfunction and glucose dysregulation in rats with Alzheimer's disease and type 2 diabetes. Partial pancreatectomy (Px) and ICV β-amyloid (25-35) infusion into the CA1 region were fed either control diet (AD-CON), 10 % cooked soybeans (CSB), 10 % TFC, or 10 % SFC in a high fat diet for 8 weeks. Px rats infused β-amyloid (35-25) as a normal-control group (Non-AD-CON). SFC increased isoflavonoid aglycones, DDMP soyasaponin βg, E soyasaponin Be and lysoposphatidylcholines in comparison to CSB. SFC markedly decreased its accumulation in β-amyloid deposition in AD rats and improved hippocampal insulin signaling (pAkt → pGSK → pTau) that exacerbated in AD-CON rats. AD rats markedly impaired cognitive function than Non-AD-CON rats as measured by a water maze and passive avoidance tests while the disturbance was prevented in an ascending order of CON < CSB and TFC < SFC. In comparison to Non-AD rats, AD-CON rats lowered whole body glucose infusion rates and increased hepatic glucose output at hyperinsulinemic state during euglycemic hyperinsulinemic clamp which SFC normalized in AD rats. Interestingly, insulin secretion, especially at the second phase during hyperglycemic clamp, was higher in AD-CON rats, compared to Non-AD rats while CSB, TFC, SFC lowered it in AD-rats. However, SFC restored β-cell mass in AD rats that reduced β-cell mass by increased β-cell apoptosis. β-Amyloid accumulation in the hippocampus exacerbated insulin resistance and decreased β-cell mass and SFC prevented their exacerbation in AD diabetic rats.
