It has been suggested that Sorghum, a rich source of phytochemicals, has a hypoglycemic effect, but the mechanism is unknown. We investigated the effects of oral administration of sorghum extract (SE) on hepatic gluconeogenesis and the glucose uptake of muscle in streptozotocin-induced diabetic rats for six weeks. Male Wistar rats were divided in five groups (n=5 per group): normal control (NC), rats with STZ-induced diabetic mellitus (DM), diabetic rats administrated 0.4 g/kg body weight of SE (DM-SE 0.4) and 0.6 g/kg body weight of SE (DM-SE 0.6), and diabetic rats administrated 0.7 mg/kg body weight of glibenclamide (DM-G). Administration of SE and G reduced the concentration of triglycerides, total and LDL-cholesterol and glucose, and the area under the curve of glucose during intraperitoneal glucose tolerance tests down to the levels observed in non-diabetic rats. In addition, administration of 0.4 and 0.6 g/kg SE and 0.7 mg/kg glibenclamide (G) significantly reduced the expression of

Regulation of hepatic gluconeogenesis by hormones insulin and glucagon is central to glucose homeostasis. Recent work has proposed that amongst the salt inducible kinase isoforms (SIK1, 2 and 3), members of the AMPK-related kinase family, the SIK2 isoform may play a role as signalling mediator in the control of insulin- and glucagon-regulated hepatic gluconeogenesis. However, the mechanisms of the hormonal-regulation of SIK2 in liver remain controversial, with much of the data based on the studies in non-hepatic tissues/cells. Therefore, the exact molecular regulation of SIK2 by these hormones in the liver required robust and intensive molecular/biochemical research coupled to physiological readout (e.g. gluconeogenesis). My studies with phosphopeptide mapping by mass spectrometry followed by verification with well-characterised phospho-specific antibodies revealed that SIK2 was phosphorylated on Ser343, Ser358, Thr484 and Ser587 in response to glucagon and fasting but not following insulin ...
The last lesson covered how insulin, glucagon, and allosteric regulators from within the liver ensure that the liver only engages in gluconeogenesis when it can and when it needs to. This lesson focuses on an additional layer of regulation: cortisol. Cortisol is the principal glucocorticoid in humans. Glucocorticoids are steroid hormones produced by the adrenal cortex that increase blood glucose. Cortisol has multiple actions on the liver, muscle, adipose, and pancreas that all converge on making glucose more available to the brain. Among them, it increases movement of fatty acids from adipose to the liver, which provide the energy for gluconeogenesis, and the movement of amino acids from skeletal muscle to the liver, which provide the building blocks for gluconeogenesis. Cortisol serves both to antagonize insulin, thereby acutely increasing gluconeogenesis, and to increase the synthesis of gluconeogenic enzymes, which amplifies all other pro-gluconeogenic signaling and increases the total capacity for
Under fasting conditions, increases in circulating concentrations of glucagon maintain glucose homeostasis via the induction of hepatic gluconeogenesis. Triggering of the cAMP pathway in hepatocytes stimulates the gluconeogenic program via the PKA-mediated phosphorylation of CREB and dephosphorylation of the cAMP regulated CREB coactivators CRTC2 and CRTC3. In parallel, decreases in circulating insulin also increase gluconeogenic gene expression via the de-phosphorylation and activation of the forkhead transcription factor FOXO1. Hepatic gluconeogenesis is increased in insulin resistance where it contributes to the attendant hyperglycemia. Whether selective activation of the hepatic CREB/CRTC pathway is sufficient to trigger metabolic changes in other tissues is unclear, however. Modest hepatic expression of a phosphorylation-defective and therefore constitutively active CRTC2S171,275A protein increased gluconeogenic gene expression under fasting as well as feeding conditions. Circulating ...
I am using the term gluconeogenesis in this lecture to denote any new formation of carbohydrate from non-carbohydrates. These non-carbohydrates include amino acids, as well as the lactate continuously produced in the body, e.g. in blood cells and in the exercised muscles. When lactate is the precursor of carbohydrate the formation of glucose from it constitutes a re-formation rather than a new formation as the lactate has been derived from glucose. But as the enzymic mechanisms of glucose formation from lactate and from amino acids are essentially the same, it is reasonable to treat them jointly. Gluconeogenesis is a biosynthetic process of major importance. I intend to review first some aspects of the physiological role of gluconeogenesis. This will lead to the fact that the amounts of carbohydrate which are synthesized vary within very wide limits-between almost nil and perhaps 200 g per day in the case of the human adult-and this will bring me to the main subject: the question of how the rate ...

Insulin resistance results in dysregulated hepatic gluconeogenesis that contributes to obesity-related hyperglycemia and progression of type 2 diabetes mellitus (T2DM). Recent studies show that MAPK phosphatase-3 (MKP-3) promotes gluconeogenic gene transcription in hepatoma cells, but little is known about the physiological role of MKP-3 in vivo. Here, we have shown that expression of MKP-3 is markedly increased in the liver of diet-induced obese mice. Consistent with this, adenovirus-mediated MKP-3 overexpression in lean mice promoted gluconeogenesis and increased fasting blood glucose levels. Conversely, shRNA knockdown of MKP-3 in both lean and obese mice resulted in decreased fasting blood glucose levels. In vitro experiments identified forkhead box O1 (FOXO1) as a substrate for MKP-3. MKP-3-mediated dephosphorylation of FOXO1 at Ser256 promoted its nuclear translocation and subsequent recruitment to the promoters of key gluconeogenic genes. In addition, we showed that PPARγ coactivator-1α ...
the measurement of the gluconeogenetic component of glucose production has been the goal of much developmental effort. Briefly, gluconeogenesis is the conversion of nonglucose substrate to glucose. A maximal rate of net gluconeogenesis can therefore be estimated from the uptake of all possible substrates by the liver (let us consider only this organ for the sake of simplicity) (1, 20, 28). An alternative, direct measurement is the simultaneous determination of glycogenolysis [by biopsy or NMR measurements (19, 25)] and the rate of total glucose production, gluconeogenesis being the difference. Clearly, these more direct methods cannot be frequently implemented in humans because of the degree of invasiveness or expense involved. Indirect measures of gluconeogenesis have therefore been sought. These have almost always involved the use of tracers, or isotopically labeled substrate and glucose. The basis of those estimates is the dilution principle in the measurement of total hepatic glucose ...
Author Summary That sugar can be converted into fatty acids in humans is a well-known fact. The question whether the reverse direction, i.e., gluconeogenesis from fatty acids, is also feasible has been a topic of intense debate since the end of the 19th century. With the discovery of the glyoxylate shunt that allows this conversion in some bacteria, plants, fungi and nematodes it has been considered infeasible in humans since the corresponding enzymes could not be detected. However, by this finding only a single route for gluconeogenesis from fatty acids has been ruled out. To address the question whether there might exist alternative routes in humans we searched for gluconeogenic routes from fatty acids in a metabolic network comprising all reactions known to take place in humans. Thus, we were able to identify several pathways showing that this conversion is indeed feasible. Analyzing evidence concerning the detected pathways lends support to their importance during times of starvation, fasting,
These data demonstrate that chronic hyperglucagonemia, when accompanied by increases in gluconeogenic precursor availability and adequate circulating concentrations of NEFA, can contribute to the infection-induced increase in glucose production and gluconeogenesis. These data confirm that even in an animal reliant predominantly on gluconeogenesis, combined increases in lactate and alanine uptake by the liver are unable to increase hepatic glucose output. If the substrate-induced suppression of NEFAs is prevented and/or NEFAs are increased, increases in gluconeogenic precursor supply can support an increase in hepatic glucose production.. Chronic hyperglucagonemia markedly enhanced the importance of the liver in disposal of the exogenous alanine. As expected, the uptake of alanine by the liver increased in parallel with the rise in alanine levels. This is reflected in the constancy of net fractional hepatic alanine extraction in the face of increases in blood alanine concentration (6). ...

Aldolase B is primary found in the liver, but can also be found in the small intestines and kidneys. B1. Interconversions of Cori Cycle If the Cori Cycle occurred and then remained in a single cell, no useful metabolic work would be complete. The reason for this is that "if the Interconversions of the Cori Cycle were to take a place within a single cell it would constitute a "futile cycle" with glucose being consumed and resynthesized at the expense of the ATP and GTP hydrolysis. (Campbell & Farrell, 2008) If this were to happen the cycle would essentially be running in opposite directions, having no affect and wasting energy. Having both the glycolysis portion and the gluconeogenesis portion going at the same time, will result in glucose being converted in to pyruvate by glycolysis and then converted back to glucose by gluconeogenesis, all this will cause a use of ATP, not making. The cycle needs to take place in order to produce ATP, an energy source for the body especially during muscle ...
In Vivo Hyperpolarized Carbon-13 Magnetic Resonance Spectroscopy Reveals Increased Pyruvate Carboxylase Flux in an Insulin-Resistant Mouse Model Philip Lee,1,2 Waifook Leong,1,3 Trish Tan,1,3 Miangkee Lim,1 Weiping Han,1,3,4 and George K. Radda1 The pathogenesis of type 2 diabetes is characterized by impaired insulin action andincreased hepatic glucose production (HGP). Despite the importance of hepatic metabolicaberrations in diabetes development, there is currently no molecular probe that allows mea-surement of hepatic gluconeogenic pathways in vivo and in a noninvasive manner. In thisstudy, we used hyperpolarized carbon 13 (13C)-labeled pyruvate magnetic resonance spec-troscopy (MRS) to determine changes in hepatic gluconeogenesis in a high-fat diet (HFD)-induced mouse model of type 2 diabetes. Compared with mice on chow diet, HFD-fed micedisplayed higher levels of oxaloacetate, aspartate, and malate, along with increased 13C labelexchange rates between hyperpolarized [1-13C]pyruvate and its ...
In order to examine the role of fructose 2,6-bisphosphate (Fru-2,6-P2) in non-esterified-fatty-acid-stimulated gluconeogenesis, Fru-2,6-P2 levels were measured in cultured rat hepatocytes under conditions mimicking the fasted state. After addition of either 1.5 mM-palmitate or 10 nM-glucagon, [U-14C]lactate incorporation into glucose increased 2-fold, but only glucagon suppressed Fru-2,6-P2. Prevention of palmitate oxidation with a carnitine palmitoyltransferase-I inhibitor (2-bromopalmitate) diminished glucose production and Fru-2,6-P2 levels. Addition of exogenous glucose to the media increased Fru-2,6-P2 in a dose-related manner, which was further augmented by addition of palmitate. When Fru-2,6-P2 levels were examined in cells cultured under conditions mimicking the fed state (significantly higher basal Fru-2,6-P2 levels and lower glucose production), palmitate oxidation was associated with a significant fall in Fru-2,6-P2. In conclusion, the present studies have demonstrated a dissociation ...
Hepatocytes obtained from starved rats were incubated in oxygenated Krebs bicarbonate buffer containing 2% defatted bovine serum albumin. DL-alpha-Lipoic (dithio-octanoic) acid (1.0 mM) caused striking reductions in hepatic glucose output in the presence of each of the following substrates: pyruvate, lactate, alanine, dihydroxyacetone, glycerol, and fructose. With lactate as substrate, 0.1-1.0 mM-lipoate caused a concentration-dependent inhibition of gluconeogenesis. With the same substrate, e.g. lactate, 0.25-2.0 mM-octanoate abolished the effect of lipoate in a dose-dependent manner. Additional experimental data are presented which support the concept that the antigluconeogenic effects of lipoic acid in liver can be attributed largely, if not entirely, to sequestration of intramitochondrial coenzyme. A, presumably as lipoyl-CoA, bisnorlipoyl-CoA, or tetranorlipoyl-CoA. ...
We have shown that depletion of KLF15 by RNAi resulted in downregulation of the expression of genes for gluconeogenic enzymes such as PEPCK and G6Pase in cultured hepatocytes. Our results suggest that KLF15 binds directly to the promoter region of the PEPCK gene and regulates the expression of this gene in coordination with the transcriptional coactivator PGC1α. Moreover, the acute ablation of KLF15 specifically in the liver resulted in suppression of gluconeogenic gene expression in mice. These results thus indicate that KLF15 contributes to the regulation of genes for gluconeogenic enzymes. Mice with genetic KLF15 deficiency, however, were previously found to exhibit reduced hepatic expression of genes for amino acid catabolic enzymes but not of those for PEPCK and G6Pase (10). This apparent discrepancy with our present results might be attributable to a secondary effect of inborn deficiency of KLF15 in the entire body that leads to compensation for the lack of the transcription factor. In ...
TY - JOUR. T1 - Dietary marine fish oils and insulin action in type 2 diabetes. AU - Karakas, Siddika E. PY - 1993. Y1 - 1993. N2 - Supplementation of omega-3 fish oils (n-3 FO) usually worsens the glycemic control in type 2 diabetic subjects. This may be a dose-related phenomenon and is reversed after discontinuation of the n-3 FO supplementation. An increase in the daily caloric intake, due to the fat content of n-3 FO supplements, and a consequent weight gain may contribute to the increase in hyperglycemia. Mechanisms of the increase in hyperglycemia include: (1) n-3 FO may interfere with insulin secretion from the pancreas, and this in turn can cause an increase in the hepatic glucose output and/or a decrease in the glucose uptake by the peripheral tissues; (2) n-3 FO may primarily decrease the sensitivity of liver to insulin action and consequently increase gluconeogenesis and/or glycogenolysis and/or decrease the glycogenesis; (3) n-3 FO may primarily affect the sensitivity of peripheral ...

They provided the following example as to how such might occur - [o]ne source of protein loss is hepatic gluconeogenesis, whereby amino acids are used to produce glucose. This is inhibited by insulin, as is the breakdown of muscle proteins to release amino acids, and therefore occurs mainly during periods of fasting. However, inhibition of gluconeogenesis and protein catabolism is impaired when insulin release is abnormal, insulin resistance occurs, or when circulating levels of free fatty acids in the blood are high. These are interdependent conditions that are associated with overweight and obesity, and are especially pronounced in type 2 diabetes. It might be predicted that the result of higher rates of hepatic gluconeogenesis will be an increased requirement for protein in the diet. Unless either more high-P, low-C+F items are included in the diet (i.e. scenario 2), or rates of removing excess co-ingested C + F are increased, weight gain will occur. And the system becomes unstable - further ...

Hyperglycemia has detrimental effects on normal organ functions in people with diabetes, chiefly contributing to the development of diabetic complications in both central and peripheral organs (1). Hyperglycemia, a hallmark of diabetes, results from dysregulation of both glucose intake/production and uptake/utilization. In type 1 diabetes, due to pancreatic β-cell death and insulin deficiency, glucose uptake and disposal decrease significantly while endogenous glucose production increases. In type 2 diabetes, due to insulin resistance and impaired insulin secretion, glucose homeostasis is similarly dysregulated. With regard to the endogenous glucose production, there are two metabolic processes-gluconeogenesis and glycogenolysis. The liver is the major organ responsible for both processes (2). Thus, the control of hepatic glucose production is highly relevant to the treatment of both type 1 and type 2 diabetes.. Hepatic gluconeogenesis is regulated at multiple levels, including expression of ...

Many patients with type 2 diabetes go on to require insulin therapy to achieve adequate control. A need remains to develop new classes of oral hypoglycemic agents to complement those already in use. A useful target is the inappropriately elevated endogenous glucose production present in patients with type 2 diabetes. This review discusses mechanisms of increased glucose production and possible strategies and targets for its suppression. Several approaches are being investigated, including inhibitors of glycogenolysis and gluconeogenesis, inhibitors of stimulatory hormones or their receptors, metabolic modulators, and agents that alter gene expression. There is a high probability that one of these approaches will soon result in a safe and effective inhibitor of glucose production. ...

If you burn protein in a bomb calorimeter, it shows 4 kcal of energy produced per gram of protein. However, in a human, protein often goes to structural usage prior to becoming fuel. And the proteins that go into your hair, nails, skin, GI lining, and other such structural uses obviously never become fuel. Further, some of the proteins that come back into circulation after serving as a muscle cell can spill into the urine if the dump from damaged muscle is fast/large enough. Lastly, therere folks that say even protein that goes directly into gluconeogenesis is converted with efficiency loss. IOW - its hard to know exactly how much of proteins caloric potential is ever actualized. So if you care about calories, it may make more sense to use a conversion factor of 3.2 kcal/gram than the 4 kcal/gram that most of us have heard over the years ...

X. campestris pv. campestris propagates and spreads in the apoplast of the host plant after infection (14, 29). Thus, the ability to acquire nutrients from the apoplast is critically important for it to cause disease. However, the nutritional requirements of X. campestris pv. campestris during infection and the molecular mechanism by which it acquires nutrients from the apoplast are still unclear. The observation that disruption of the gluconeogenic pathway resulted in significant reductions both in multiplication in planta and virulence of X. campestris pv. campestris suggested that the apoplast is lacking hexose but rich in gluconeogenic substrates (C2 or C3 compounds or the intermediates of the TCA cycle), and the gluconeogenic pathway is the only route to utilize these carbon sources to maintain the carbon and energy supplies for normal growth of X. campestris pv. campestris during infection. Furthermore, disruption of the glyoxylate cycle (mutation in aceA or mls) of X. campestris pv. ...
Abstract: Phase alterations in the intensity of gluconeogenesis were observed in 92 rats subjected to hypokinesia within 1-30 days. At early periods of fixation of the animals gluconeogenesis was increased in all the tissues studied; the activation was especially distinct within the first 7 days of the experiment. Intensity of gluconeogenesis was similar to control values within 15 days of hypokinesia and a slight activation was detected within 30 days. Content of glucose was maximal in liver tissue within 3 days but the glycogen level was distinctly decreased in all the periods of experiments except of the 7th day. The pattern of gluconeogenesis in liver tissue as well as content of carbohydrates should be taken into consideration in the course of prophylaxis and treatment of the unfavourable after-effects of hypokinesia ...
