Inhibition of DYRK1A and GSK3B induces human β-cell proliferation

Insufficient pancreatic β-cell mass or function results in diabetes mellitus. While significant progress has been made in regulating insulin secretion from β-cells in diabetic patients, no pharmacological agents have been described that increase β-cell replication in humans. Here we report aminopyrazine compounds that stimulate robust β-cell proliferation in adult primary islets, most likely as...

Inhibition of DYRK1A Stimulates Human β-Cell Proliferation

Restoring functional β-cell mass is an important therapeutic goal for both type 1 and type 2 diabetes (1). While proliferation of existing β-cells is the primary means of β-cell replacement in rodents (2), it is unclear whether a similar principle applies to humans, as human β-cells are remarkably resistant to stimulation of division (3,4). Here, we show that 5-iodotubercidin (5-IT), an annotat...

Phoenix dactylifera L. Fruit Induces Cell Proliferation of A2780, A172 and HFFF2 Cell Lines

Dates fruit has been used as staple food in the Middle East for thousands of years and various types of dates are found worldwide. Dates and their constituents show various roles in diseases prevention and treatment through anti-oxidant, anti-inflammatory, anti-bacterial activity. In the present study we investigated the activity of aqueous and n-hexane extracts of Phoenix dactylifera L. fruit ...

Hypericin-photodynamic therapy inhibits proliferation and induces apoptosis in human rheumatoid arthritis fibroblast-like synoviocytes cell line MH7A

Objective(s): To elucidate the effects and potential mechanisms of hypericin-photodynamic therapy (HYP-PDT) for treating the human rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) MH7A cell-line. Materials and Methods: MH7A cells were subjected to HYP-PDT intervention and apoptosis was evaluated via MTT, nuclear staining, and flowcytometry analyses. Intracellular reactive oxygen spec...

Human β-Cell Proliferation and Intracellular Signaling

A major goal in diabetes research is to find ways to enhance the mass and function of insulin secreting β-cells in the endocrine pancreas to prevent and/or delay the onset or even reverse overt diabetes. In this Perspectives in Diabetes article, we highlight the contrast between the relatively large body of information that is available in regard to signaling pathways, proteins, and mechanisms ...
