But there are structured diabetes education programs that your doctor must enable you to attend such a course. Linaglyptin works in a similar way to Sitagliptin above, but is is safe in reduced renal function.
If you compliance is not good and you only want twice daily injections and don't want to test much, and new ultralongacting insulin degludec may help. October 23, 2013 by Catherine 1 Comment Type 2 diabetes which used to be known as middle aged diabetes, is the most universally widespread form of diabetes, but the causes of type 2 diabetes are not clear cut they are caused by a combination of factors, which include insulin resistance, this condition occurs when your liver, muscles and fat cannot use insulin. Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels.
One of the causes of Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Causes of type 2 diabetes are not fully understand, but non the less there are some fairly accurate pointers. However modern research at Newcastle university is identifying one of the causes of type 2 diabetes as a result of crossing your personal fat threshold.This would account for the fact that some obese people will never develop diabetes.
A healthy person’s body keeps blood glucose levels in a normal range through several complex mechanisms.
When blood glucose levels drop overnight or due to a skipped meal or heavy exercise, the pancreas releases glucagon into the blood. My name is Leo, and I refused to accept that my diagnosis for diabetes type 2 was permanent. Diabetic Romantic Thai Dinner RecipesYesterday we examined the preparation of fish and seafood to prepare a diabetic romantic Thai dinner recipe.Thai fish dinners are great for diabetics  because they focus on fresh healthy food simply prepared. Diabetic Romantic Thai Dinner PreparationIn general, the food from Southeast Asia is a lot cleaner than Western food, because it uses fresh natural ingredients and very little processed food. Because I have overcome diabetes I know intimately the struggles and hardships that diabetes causes.
Type 2 diabetes mellitus (T2DM) is a polygenic metabolic disease characterized by elevated blood sugar levels due to pancreatic beta-cell functional impairment and insulin resistance in tissues such as skeletal muscle, adipose tissue and the liver (1). This chronic disease process is accompanied by complications in various vital organs and can be associated with a higher risk for cardiovascular events, neurological changes, kidney impairment, osteoporosis, cognitive impairment (CI) and dementia (4).
The notable epigenetic mechanisms that can alter gene expression are DNA methylation, histone modification, and non-coding RNA-mediated pathways (Figure 1).
Some of the environmental factors occurring during embryogenesis (such as maternal diet and intrauterine nutrition) and early development could impact health and disease states even in adulthood (16).
In recent years many reports strongly point to the critical role of epigenetic modifications in the development and pathogenesis of cancer, asthma, arthritis, hypertension, etc.
Analysis of pancreatic beta cells from diabetic and healthy individuals revealed epigenetic changes in approximately 850 genes with a fold change between 5-59% (1).
Another gene UNC13B located on chromosome -9, is found to be hyper-methylated in diabetic patients and hyperglycemia upregulates its expression and is implicated in diabetic nephropathy (20). Diabetes is a complex metabolic disorder characterized by hyperglycemia, insufficient insulin secretion and insulin resistance. About This SiteAs it is believed that epigenetics holds the key to many of life's mysteries, our intiative is to bring awareness and knowledge of epigenetics to a larger scientific community as well as to the general population.
The scientists have discovered the gene, which is responsible for the obesity in a human body. This gene is mainly inherited from mum and only this gene decides whether the kid will be obese or not. The above study was performed by the researchers from King’s College London and the University of Oxford. They further established that the protein produced by the BRCA 1 gene binds with a protein known to play an important role in the metabolism of fat in muscle cells known as Acetyl-CoA carboxylase or ACC. Once they established that the two proteins complex together, they sought to answer if BRCA1 plays a critical role in regulating muscle metabolic function.
New finding represents a leap in the field of quantum computers according to experts, and already is drawing significant scientific attention. Symptoms of type 2 diabetes may develop gradually over a long period of time, and they can be subtle; some people with type 2 diabetes remain undiagnosed for years.
Type 2 diabetes develops most often in middle-aged and older people who are also overweight or obese.
Within one year I had cured my diabetes and come down from the maximum Metformin to Zero medication.

Millions of people around the globe are diagnosed with diabetes, and its incidence is estimated to double by 2030.
Though diabetes has a strong genetic component, as it tends to run in families, environment also has a significant role in triggering this condition.
Briefly, in DNA methylation, a methyl group is added at the 5-carbon of the cytosine to form 5-methylcytosine. Genome-wide association studies (GWAS) of recent times are helping in detecting and identifying more genes responsible for T2DM and could provide a complete list of genetic variants associated with this disease in the future (13).
In addition to these, exposure to heavy metals, pesticides, cigarette smoking, and even deficiencies of some nutrients (folate and methionine) can stimulate alteration in epigenetic pathways (8). Over 100 of the genes also had altered expression and many of these could contribute to reduced insulin production.
An in vitro study showed increased histone acetylation which in turn promoted inflammatory gene expression (22).
Incidence of diabetes is growing at an alarming rate at about 4660 new cases per day in the US. Genome –wide DNA methylation analysis of human pancreatic islets from Type 2 Diabetic and Non-diabetic donors identifies candidate genes that influence insulin secretion.
Effects of prenatal exposure to the Dutch famine on adult disease in later life: an overview. Genome wide survey reveals predisposing diabetes type 2-related DNA methylation variation in human peripheral blood. Epigenetic regulation of PPARGC1A in human type 2 diabetic islets and effect on insulin secretion. She teaches physiology, human biology and cell biochemistry to undergraduate students and her research interests include xenobiotic toxicity, environmental pollution and diabetes. It is involved in every aspect of life and such reversible, heritable changes affect the way we live as well as our future generations.
It also helps in managing the weight in the body and behavior of the other genes present in the fat of the body. Spangenburg and colleagues, including researchers from the University of Maryland School of Medicine, Brigham Young University, Karolinska Institutet in Sweden, and East Carolina University, found that the BRCA1 protein exists in both mouse and in human skeletal muscle.
To do so, they “knocked out” the gene so that it was no longer being expressed in the muscle cells cultured from healthy, active and lean female subjects. The removal of BRCA1 from the cells, which simulated what could happen in the cells of a person with a BRCA1 mutation, resulted in increased lipid storage, decreased insulin signaling, reduced mitochondrial function and increased oxidative stress. Type 2 is progressive: the pancreas produces less insulin each year, more treatment and eventually insulin is often needed. Fifty years ago diabetes was called the silent killer because often it did not present symptoms until it had developed to the complications stage. The disease, once rare in the young is becoming more common in overweight and obese children and adolescents. Alternatively if you want a private reply to a question feel free to use the contact page at the top of the blog. It has become one of the most challenging public health issues of 21st century and the fifth leading cause of death worldwide (2).
The notable risk factors for developing diabetes are obesity, advance in age, and sedentary lifestyle with lack of physical activity. Diabetes is multifactorial disease indicating its emergence in individuals with genetic predisposition that depends on other factors.
It is proposed that the environmental factors activate an intracellular signal, which, in turn marks the exact chromatin site for epigenetic modifications (14)(15) resulting in altered gene expression.
Additionally, obesity and age are also shown to alter these epigenetic mechanisms and might result in T2DM (5). Genes involved in the production and release of insulin are reported to be altered in diabetic islets compared to non-diabetic ones. About 17 candidate genes for type 2 diabetes including TCF7L2, THADA, KCNQ1, FTO, and IRSI were reported to be differentially methylated in pancreatic islets of type 2 diabetic population.
Over-expression of this miRNA is found to reduce glucose-stimulated insulin release while its inhibition resulted in increase in insulin secretion (21). Lastly, hyperglycemia induced histone modifications and DNA methylation of pro-inflammatory genes triggering the vascular inflammation are also reported (23).


This disease runs in families, indicating that it has a genetic origin and genome wide association studies indicate about 100 gene variants associated with this disease. Insulin resistance induced by physical inactivity is associated with multiple transcriptional changed in skeletal muscle in young men.
The other vital role of this gene is controlling body-mass index, cholesterol, insulin and glucose levels.
This is the first evidence since the discovery of BRCA1 in 1994 that the gene is expressed in human muscle cells. This was done using shRNA technology specific for BRCA1 in human myotubes (skeletal muscle fiber cells).
These are all key risk factors for the development of metabolic diseases, such as obesity, type 2 diabetes and cardiovascular disease. However, this process is a lot slower with regular exercise, a healthy diet, and keeping thin. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes. The American Diabetes Association (ADA) estimates that 1.7 million Americans are diagnosed with diabetes every year, which means about 4,660 new diagnoses of diabetes daily (3).
However, many people with these risk factors do not develop diabetes and research studies indicate that complex interaction between genes and environment through epigenetic modifications makes a person susceptible to develop diabetes (5). Increased expression and decreased methylation of CDKN1A and PDE7B gene in type 2 diabetes was reported to result in impaired glucose-stimulated insulin release. Thus emergence of diabetes in an individual is quite complex and results from the complex interaction between genes and environment. Though genes predispose a person to develop this disease, environment also contributes to its prevalence.
Now the doctors can step ahead in examining weigh-related diseases like heart disease and diabetes. Espen Spangenburg, associate professor of kinesiology, and his laboratory team are the first to identify that the BRCA1 protein is expressed in the skeletal muscle of both mice and humans, and that it plays a key role in fat storage, insulin response and mitochondrial function in skeletal muscle cells. Of the 30 million people who currently have diabetes in the United States, about 90% have T2DM. Epigenetic mechanisms and their role in the development of diabetes and the significance of the environment in shaping the epigenome of an individual is presented in this article. This observation provides an evidence of diabetes associated epigenetic modifications and associated impaired insulin release (1).
This gene was found to be under-expressed and hypermethylated in type 2 diabetes pancreatic islets.
This type of regulation of gene expression by the epigenetic mechanisms explains how cells with the same DNA can differentiate into different cell types with different phenotypes (5).
Recently it is pointed out that small changes in gene expression may have a pronounced effect on diabetes over long periods of time (17).
These modifications in histones bring significant alterations in their functions (9) resulting in promotion or repression of gene transcription (10).
In many tissues PPARGC1A gene encodes a transcriptional coactivator which regulates mitochondrial oxidative metabolism. Many studies point to epigenetic modifications (DNA methylation and histone modifications) in mediating this interaction.
MicroRNAs (miRNA) are a class of non-coding single stranded RNAs of 19-25 nucleotides in length, which are reported to have a key role in the regulation of gene expression (5) (Figure 1).
In type 2 diabetic pancreatic islets the DNA methylation of PPARGC1A promoter was reported to be doubled and the expression of PPARGC1A gene was significantly reduced in comparison to non-diabetic islet cells.
This gene was also down-regulated in individuals who were physically inactive, a lifestyle of which is established to be one of the risk factors for diabetes (19).
