Berberine has been used for the adjuvant treatment of type 2 diabetes mellitus, hyperlipidemia (high levels fats), and hypertension blood pressure). Also, it different effects on diarrhea, inflammation, cancer. Berberine, is a profoundly common compound in Berberis species. Although cretica one species, unknown whether anti-diabetic yet. synergistic various compounds together with berberin or s...

Human induced pluripotent stem cells (hiPSCs) provide a potential resource for regenerative medicine. To identify the signalling pathway(s) contributing to the development of functional β cells, we established a tracing model consisting of dual knock-in hiPSCs (INS-Venus/NGN3-mCherry) (hIveNry) expressing the fluorescent proteins Venus and mCherry under the control of intrinsic insulin (INS) an...

Whether hyperinsulinemia is required for stimulation of net hepatic glucose uptake (NHGU) by a selective serotonin reuptake inhibitor (SSRI) was examined in four groups of conscious 42-h-fasted dogs, using arteriovenous difference and tracer ([3-3H]glucose) techniques. Experiments consisted of equilibration (-120 to -30 min), basal (-30 to 0 min), and experimental periods (Exp; 0-240 min). Duri...

Dictyostelium discoideum homogenates contain phosphatase activity which rapidly dephosphorylates Ins(1,4,5)P3 (D-myo-inositol 1,4,5-trisphosphate) to Ins (myo-inositol). When assayed in Mg2+, Ins(1,4,5)P3 is dephosphorylated by the soluble Dictyostelium cell fraction to 20% Ins(1,4)P2 (D-myo-inositol 1,4-bisphosphate) and 80% Ins(4,5)P2 (D-myo-inositol 4,5-bisphosphate). In the particulate frac...

We demonstrated previously that the activation of ALK7 (activin receptor-like kinase-7), a member of the type I receptor serine/threonine kinases of the TGF-β superfamily, resulted in increased apoptosis and reduced proliferation through suppression of Akt signaling and the activation of Smad2-dependent signaling pathway in pancreatic β-cells. Here, we show that Nodal activates ALK7 signaling a...

BACKGROUND Type 2 diabetes mellitus (T2D) is a metabolic disease characterized by dysfunction of pancreatic beta cell and insulin resistance. Liraglutide, which has many special anti-diabetes biological effects, is found to inhibit beta cell death and ameliorate endoplasmic reticulum stress (ERs) induced by free fatty acid (FFA). Macroautophagy (hereafter referred to as autophagy) altered by FF...

Expression of muscarinic receptors in rat islets, RINm5F cells, and INS-1 cells was established by reverse transcriptase-polymerase chain reaction (RT-PCR) and quantified by RNase protection. Both methods indicated that m3 and m1 receptors were expressed approximately equally in the various cellular preparations and to a much greater extent than the m5 subtype. However, the cell lines, especial...
