epidemiological evidence shows that cancer and diabetes are major causes of death in the world. type2 diabetes increases the risk of cancer-specific mortality. this review relates diabetic therapies, diabetes and cancer.all published papers in this field were searched, looking into such databases as science direct, isi web of knowledge, pubmed and scopus.in cancer patients, metformin improves p...

BACKGROUND Previous studies suggest that metformin by reducing hyperinsulinemia is clinically useful in the treatment of polycystic ovary syndrome (PCOS). Our Objective was to observe the role of metformin in correcting oligomenorrhea/amenorrhea and anovulation within six month in hyperinsulinemic women with PCOS. Another aim was to assess the decrease in hyperinsulinemia and body weight by met...

Biguanides have been developed for the treatment of hyperglycemia and type 2 diabetes. Recently, metformin, the most widely prescribed biguanide, has emerged as a potential anticancer agent. Epidemiological, preclinical and clinical evidence supports the use of metformin as a cancer therapeutic. The ability of metformin to lower circulating insulin may be particularly important for the treatmen...

Polycystic Ovary Syndrome (PCOS) is characterized by ovulatory disturbances, hyperandrogenaemia and hyperinsulinemia secondary to increased insulin resistance. In PCOS, hyperinsulinemic insulin resistance is of interest because skeletal muscle may be resistant to insulin in terms of glucose metabolism, while the ovaries remain sensitive to insulin with regard to stimulation of testosterone bios...

Accumulating epidemiological evidence shows that obesity is associated with an increased risk of several types of adult cancers, including endometrial cancer. Chronic hyperinsulinemia, a typical hallmark of diabetes, is one of the leading factors responsible for the obesity-cancer connection. Numerous cellular and circulating factors are involved in the biochemical chain of events leading from ...

CLINICAL PHARMACOLOGY Mechanism of Action Metformin is an antihyperglycemic agent which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Its pharmacologic mechanisms of action are different from other classes of oral antihyperglycemic agents. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucos...

Hyperinsulinemia is believed to be a key link in the enigmatic generation of the symptoms of polycystic ovarian syndrome (PCOS), which include anovulatory infertility and the skin stigmata induced by hyperandrogenism. Regression of these symptoms may be achieved by reducing the hyperinsulinemia. Metformin, an insulin-sensitizing agent, has been proven to be of clinical usefulness both in the sh...

Two important, related pathways are involved in cancer growth: the insulin/insulin-like growth factor-1 (IGF1) signaling pathway, which is activated when nutrients are available, and the adenosine mono-phosphate-activated protein kinase (AMPK) pathway, activated when cells are starved for carbohydrates. Metformin inhibits transcription of key gluconeogenesis genes in the liver, increases glucos...

background: polycystic ovary syndrome (pcos) is one of the common endocrine disorders in women of reproductive ages. it is associated with a range of disorders, such as dyslipidemia, hypertension, insulin resistance (ir), compensatory hyperinsulinemia,gestational, and type 2 diabetes, and increased risk of cardiovascular morbidity. there are different treatments available for pcos. the purpose ...

Interest in the role of insulin sensitizing drugs (ISDs) as a means of reducing compensatory hyperinsulinemia in the hope of improving metabolic and reproductive functions in women with PCOS has grown measurably over the past decade. Metformin is believed to lower fasting serum insulin levels in insulin-resistance. For the management of ovulatory infertility in the nonobese PCOS population (BMI...
