Ob/ob mouse

Index Ob/ob mouse

The ob/ob or obese mouse is a mutant mouse that eats excessively due to mutations in the gene responsible for the production of leptin and becomes profoundly obese. [1]

Adipose tissue

In biology, adipose tissue, body fat, or simply fat is a loose connective tissue composed mostly of adipocytes.

Diabetes mellitus type 2

Diabetes mellitus type 2 (also known as type 2 diabetes) is a long-term metabolic disorder that is characterized by high blood sugar, insulin resistance, and relative lack of insulin.

Dominance (genetics)

Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.

Gene

In biology, a gene is a sequence of DNA or RNA that codes for a molecule that has a function.

Genetic screen

A genetic screen or mutagenesis screen is an experimental technique used to identify and select for individuals who possess a phenotype of interest in a mutagenized population.

Hormone

A hormone (from the Greek participle “ὁρμῶ”, "to set in motion, urge on") is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.

Hyperglycemia

Hyperglycemia, or high blood sugar (also spelled hyperglycaemia or hyperglycæmia) is a condition in which an excessive amount of glucose circulates in the blood plasma.

Hyperinsulinemia

Hyperinsulinemia, or hyperinsulinaemia is a condition in which there are excess levels of insulin circulating in the blood relative to the level of glucose.

Hyperplasia

Hyperplasia (from ancient Greek ὑπέρ huper, "over" + πλάσις plasis, "formation"), or hypergenesis, is an increase in the amount of organic tissue that results from cell proliferation.

Jackson Laboratory

The Jackson Laboratory (often abbreviated as JAX) is an independent, nonprofit biomedical research institution dedicated to contributing to a future of better health care based on the unique genetic makeup of each individual.

Leptin

Leptin (from Greek λεπτός leptos, "thin"), "the hormone of energy expenditure", is a hormone predominantly made by adipose cells that helps to regulate energy balance by inhibiting hunger.

Model organism

A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms.

Mutant

In biology and especially genetics, a mutant is an organism or a new genetic character arising or resulting from an instance of mutation, which is an alteration of the DNA sequence of a gene or chromosome of an organism.

Obesity

Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health.

Pancreatic islets

The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (hormone-producing) cells, discovered in 1869 by German pathological anatomist Paul Langerhans.

Polyphagia

Polyphagia or hyperphagia is excessive hunger or increased appetite.
