Diabetes’ prevalence is increasing at an alarming rate. Normally, insulin-secreting β-cells in the pancreas regulate proper glucose absorption and storage. Type 1 and Type 2 diabetes are characterized by decreased functional β-cell mass and insulin production (1). Diabetes also results in increased circulating glucose and fatty acid levels, which damage and destroy β-cells over time (2). Our study sheds further light on the palmitate and oleate-induced effects of gradually worsening hyperlipidemia and the mechanisms behind those effects; ultimately, promoting investigation into methods by which existing β-cells could be protected from harmful hyperlipidemia.

Type 1 and Type 2 diabetes are major global health concerns. Diabetes is characterized by impaired management of glucose in the bloodstream, which is due to decreased pancreatic functional β-cell mass. Functional β-cell mass is determined from the insulin secretion rate and the number of β-cells, which is determined from cellular proliferation and death rates. Increasing functional β-cell mass could cure diabetes either by enhancing pancreatic islets prior to transplantation, or by strengthening endogenous cells. Although β-cells stop proliferating around adolescence, β-cell proliferation resumes during conditions such as pregnancy and obesity (1), demonstrating that the molecular pathways necessary for replication …

Type 2 diabetes is a metabolic disorder that results in β-cell dysfunction and ultimate destruction, and leads to impaired glucose homeostasis. High rates of proliferation and differentiation of pancreatic β-cells occurs mostly during neonatal development. However, research shows these mechanisms remain intact as β-cell proliferation has been observed during pregnancy and obesity. We have shown that overexpression of the β-cell transcription factor Nkx6.1 is sufficient to induce β-cell proliferation. Exploration of the transcriptional targets of Nkx6.1 has identified histone deacetylase 1 (HDAC1) as a down-stream target of Nkx6.1. Here we demonstrate that HDAC1 overexpression is sufficient to induce β-cell proliferation, …

Type 1 and Type 2 diabetes are classified as a decrease in functional ß-cell mass, which results in impaired blood glucose regulation. Functional ß-cell mass is defined as the glucose stimulated insulin secretion rate multiplied by the total cellular mass which is determined by the proliferation and cell death rates. Though ß-cell mass proliferation rates generally decrease by adolescence, obesity and pregnancy have been shown to be times of significant ß-cell proliferation (1). This implies that the inherent molecular pathways necessary for ß-cell proliferation are present, but highly regulated. Discovering the molecular pathway of ß-cell proliferation could lead to diabetes …

Diabetes, a disease characterized by the inability of the body to maintain a normal blood glucose level, continues to affect the lives of many. In both Type I and Type II diabetes, eventual β-cell destruction results in decreased β-cell mass. Regeneration of functional β-cells and protection of such, could help reverse the effects of this disease and could possibly lead to a cure. Many studies have been done to increase functioning β-cell mass, but protecting regenerated β-cells from further apoptotic insults could greatly increase the effectiveness of β-cell transplants and other future treatments of the disease.

Journal of Undergraduate Research
Type 1 and Type 2 diabetes are major global health concerns. Both types of diabetes result in loss of functional β-cell mass, which is defined as the β-cell number multiplied by insulin secretion rate. The number of β-cells is derived from the cellular proliferation and death rates. Increasing functional β-cell mass could cure diabetes through pancreatic islet transplants or by strengthening endogenous cells. Various groups have shown that the β-cells proliferation rate is extremely low after adolescence in the majority of the population. However, β-cell proliferation has been shown to increase during physiological conditions such as pregnancy and obesity (1). …
