The invention relates to new methods and compositions for treating diabetics, pre-diabetics, and patients at risk of becoming diabetic or with impaired glucose tolerance. The invention, in one embodiment, involves activating insulin receptor substrate-2 to protect against loss of beta cell mass, protect against loss of beta cell function, rejuvenate beta cells mass, rejuvenate beta cell function or any combination thereof, thereby stimulate insulin production using an effective amount of LySB3,GluB29 insulin to patients in need of this treatment.

The miRNA miR-33 is shown to inhibit the expression of carnitine O-octaniltransferase (CROT), Carnitine palmitoyltransferase 1A (CPT1a) and hydroxyacyl-CoA-dehydrogenase (HADHB), reduce fatty acid oxidation in hepatic cells, and target the insulin receptor substrate 2 (IRS-2) independent of its ability to elevating plasma high density lipoprotein (HDL) levels. MiR-33 inhibitors are also shown to increase cholesterol efflux from peripheral cells, such as cholesterol-laden macrophages present in atherosclerotic plaques. Compositions and methods are therefore provided for treating or preventing metabolic syndrome and atherosclerosis using miR-33 inhibitors. The miR-33 inhibitors are preferably antagomirs having a single-stranded nucleic acid sequence that is complementary to at least 12 contiguous nucleotides in miR-33 and therefore forms a duplex with miR-33 under physiological conditions.

This invention is directed to a general method for the chronic treatment, potential cure, or prevention of various metabolic and related diseases in people, including diabetes, by modulating IRS2 activity in cells and tissues in the body. IRS1 and IRS2 are part of the insulin or insulin-like growth factor signaling pathway. By upregulating the levels or functional activity of IRS2, insulin is used more efficiently by the body to control nutrient levels. By upregulating IRS2 levels or functional activity in pancreatic β-cells, glucose sensing and insulin secretion are enhanced.

This invention relates to plant extracts containing nutritionally beneficial or medicinally active compounds. Some of these extracts, or the purified compounds contained therein, may be used for the nutritional support, prevention, treatment, or possible cure of various metabolic and other diseases and disorders in human beings and animals, including type 1 and type 2 diabetes, by regulating insulin signaling. This regulatory effect may include modulations of the levels and / or activity of the Insulin Receptor (IR), the Insulin-like Growth Factor (IGF) Receptor, and / or the Insulin Receptor Substrate (IRS) proteins in cells and tissues in the body.

Provided is a treatment of cancer using a dual modulator of Insulin Receptor Substrate (IRS) and signal transducer and activator of transcription 3 (Stat3), as well with other agents. The combination can be used to treat a tumor that has developed resistance to an EGFR inhibitor, EGFR antibody, mTOR inhibitor, MEK inhibitor, mutated B-Raf inhibitor, chemotherapeutic agents, and certain combinations thereof, or to prevent acquired resistance of a tumor to any of said inhibitors or agents, or to prevent tumor recurrence following cease of treatment with any of said inhibitors or agents or a combination thereof. The subject matter further provides a treatment of cancer using combination therapy comprising a dual modulator of IRS and Stat3, in combination with an immunotherapy agent. The combination can be used to sensitize a tumor to immunotherapy.

The present invention relates to a pharmaceutical composition for preventing or treating diabetes or a complication of diabetes, which includes a TENC1 (tensin like C1 domain-containing phosphatase) expression or activity suppressor, and, more specifically, relates to a pharmaceutical composition for preventing or treating diabetes or a complication of diabetes, which either suppresses the degradation of IRS-1 (insulin receptor substrate-1) or suppresses the phosphorylation of IRS-1 due to the PTPase activity of TENC1. The pharmaceutical composition according to the present invention, which is for preventing or treating diabetes or a complication of diabetes and comprises the TENC1 expression or activity suppressor as an active ingredient, can be expected to be widely usable in preventing and treating diabetes or a complication of diabetes since the pharmaceutical composition can effectively prevent the muscular dystrophy and reduction in sugar adsorption that occur due to reduction in IRS-1 by suppressing degradation of IRS-1 caused by TENC1.

The present invention relates to the development of insulin resistant skeletal muscle cell culture model useful for the screening of compounds that enhance insulin receptor (IR) and insulin receptor substrate-1 (IRS-1) tyrosine phosphorylation required against type II diabetes.

The invention provides a fructan consisting of 25 beta-D-fructoses and 1 alpha-D-glucose, and a method for preparing the fructan from Hubei dwarf lilyturf tuber serving as a raw material. The fructan has obvious effect of reducing blood sugar of mice with type 2 diabetes, simultaneously improves the sugar tolerance of the mice with the type 2 diabetes, and obviously enhances the expression of insulin receptor (InsR), insulin receptor substrate (IRS-1), protein kinase and phosphatidylinositol3-kinase (PI3-K) to further accelerate the glucose to be converted into glycogen and improve the activities of glucose-6-phosphate and glucose-6-phophatase so as to obvious reduce the insulin resistance.

The present invention relates to antisense oligonucleotides that modulate the expression of and / or function of Transcription factor E3 (TFE3) and / or Insulin Receptor Substrate 2 (IRS2) polynucleotides, in particular, by targeting natural antisense polynucleotides of Transcription factor E3 (TFE3) and / or Insulin Receptor Substrate 2 (IRS2). The invention also relates to the identification of these antisense oligonucleotides and their use in treating diseases and disorders associated with the expression of TFE3 and / or IRS2.
