Disclosed are a composition for preventing or treating diabetes, diabesity or diabetic complications, containing an oxyntomodulin analog as an active ingredient and a method for treating diabetes, diabesity or diabetic complications, including administering a pharmaceutically effective amount of an oxyntomodulin analog to a subject. The oxyntomodulin analog shows a greater activity to activate a GLP-1 receptor and a glucagon receptor, than native oxyntomodulin. The oxyntomodulin analog induces an expansion of beta-cells and increases insulin secretion, thereby reducing blood glucose levels that were increased due to a high-calorie and high-fat diet. The oxyntomodulin analog induces decreases in a body weight and appetite to improve insulin sensitivity and is useful in maintaining normal blood glucose levels.

Methods are provided for the establishment and maintenance in long term culture of hormone secreting cells. Cells are derived from tumorous or non-tumorous animal or human tissues, including ovary, endometrium, trophoblast, pituitary, thyroid, and pancreas. The cells secrete into the culture medium hormones such as estrogens, progestins, follicle-stimulating hormone, luteinizing hormone, human chorionic gonadotrophin, thyroxin, glucagon, and insulin, depending on the tissue of origin of individual cell cultures. Contact with an appropriate secretogogue causes the cells to respond with increased hormone secretion. For instance, ovarian follicular cells respond to follicle-stimulating hormone with increased estrogen and progesterone secretion. Pancreatic cells respond to elevated glucose with increased insulin secretion. The cells proliferate in in vitro for up to one year or longer, during which time they retain their hormone-secretion profile. The cells may be frozen for storage, and retain their hormone-secretion profile after thawing. The cell cultures are useful for the production of human hormones, for the bio-assay of drugs such as therapeutic gonadotrophin, for the testing of drug efficacy and design, and for toxicity testing of drugs and chemicals. The cells may also be implanted in an individual to replace deficient hormone secretion. For instance, insulin secreting pancreatic cells may be implanted in a diabetic individual as an adjunct or replacement therapy for exogenously administered insulin.

Described herein is a novel, mitochondrial encoded, open reading frame, that leads to the production of a new mitochondrial peptide. Residing within the ND-Two subunit, a specific small nucleotide polymorphism disrupts expression of this mitochondrial peptide, and is correlated with an increase in obesity and diabetes, particularly in certain ethnic populations. In vitro administration of the peptide increases insulin secretion, decreases fat accumulation and improves glucose uptake in muscle cell. Antibodies generated against the peptide can be used for detecting peptide deficiency, in addition to SNP detection, supporting diagnostic approaches. In vivo studies further revealed that administration of the peptide improves glucose tolerance, thereby providing a new therapeutic avenue for a novel diabetes therapy and decreases bodyweight, thus serving as a novel obesity therapy. Generation of synthetic analogs further enhance or abrogated activity relative to the natural peptide.
