The arcuate nucleus of the hypothalamus represents a key center for the control of appetite and feeding through the regulation of 2 key neuronal populations, notably agouti-related peptide/neuropeptide Y and proopimelanocortin (POMC)/cocaine- and amp

Pancreatic β-cells with severely knocked down cytosolic malic enzyme (ME1) and mitochondrial NAD(P) malic enzyme (ME2) show normal insulin secretion. The mitochondrial NADP malic enzyme (ME3) is very low in pancreatic β-cells, and ME3 was previousl

Pancreatic β-cell death plays a role in both type 1 and type 2 diabetes, but clinical treatments that specifically target β-cell survival have not yet been developed. We have recently developed live-cell imaging-based, high-throughput screening met

Insulin, an established mitogen that promotes breast cancer cell growth, has been implicated in the link between obesity and an increased risk of breast cancer. However, the current understanding of signaling pathways that mediate the mitogenic actio

The proglucagon gene is expressed not only in the pancreas and intestine but also in the hypothalamus. Proglucagon-derived peptides have emerged as potential regulators of energy homeostasis. Whether leptin, insulin, or cAMP activation controls progl

Acute insulin resistance is common after injury, infection, and critical illness. To investigate the role of reactive oxygen species (ROS) in critical illness diabetes, we measured hepatic ROS, which rapidly increased in mouse liver. Overexpression o

Single chain insulins (SCIs) are single polypeptide chains in which the insulin B-chain links contiguously with the insulin A-chain via an uncleaved connecting peptide. While direct linkage of insulin Band A-chains produces SCIs with little insulin r

The receptors for IGF-I (IGF-IR) and insulin (IR) have been implicated in physiological cardiac growth, but it is unknown whether IGF-IR or IR signaling are critically required. We generated mice with cardiomyocyte-specific knockout of IGF-IR (CIGF1R

Routine consumption of alcohol at low doses is associated with decreased risk of acquiring type 2 diabetes, whereas chronic and excessive alcohol consumption increases the risk. Although there is good epidemiologic evidence for these biphasic effects

We have identified Kruppel-like factor 7 (KLF7) as a new candidate for conferring susceptibility to type 2 diabetes. To ascertain the possible involvement of KLF7 in the pathogenesis of type 2 diabetes, we examined the functional roles of KLF7 in var
