Therapeutic potential of SH2 domain-containing inositol-5'-phosphatase 1 (SHIP1) and SHIP2 inhibition in cancer.
Many tumors present with increased activation of the phosphatidylinositol 3-kinase (PI3K)-PtdIns(3,4,5)P(3)-protein kinase B (PKB/Akt) signaling pathway. It has long been thought that the lipid phosphatases SH2 domain-containing inositol-5'-phosphatase 1 (SHIP1) and SHIP2 act as tumor suppressors by counteracting with the survival signal induced by this pathway through hydrolysis or PtdIns(3,4,...
متن کاملEvidence for SH2 Domain-Containing 5′-Inositol Phosphatase-2 (SHIP2) Contributing to a Lymphatic Dysfunction
The lymphatic vasculature plays a critical role in a number of disease conditions of increasing prevalence, such as autoimmune disorders, obesity, blood vascular diseases, and cancer metastases. Yet, unlike the blood vasculature, the tools available to interrogate the molecular basis of lymphatic dysfunction/disease have been lacking. More recently, investigators have reported that dysregulatio...

Introduction: Dyslypydmy is one of the risk factors of cardiovascular disease in diabetics. Dyslypydmy is diagnosed by increasing in plasma triglyceride density, decreasing HDL Cholesterol, and increasing LDL especially small LDL. Several evidences from human and animal studies indicate that the role of insulin resistance is a major cause of hypertrigly ceridemia in diabetics and people with me...
متن کاملAssociation of SH2-containing inositol phosphatase 2 with the insulin resistance of diabetic db/db mice.
SH-2-containing inositol 5'-phosphatase 2 (SHIP-2) is a physiologically important lipid phosphatase that functions to hydrolyze phosphatidylinositol (PI) 3-kinase product PI(3,4,5)P3 to PI(3,4)P2 in the negative regulation of insulin signaling. We investigated whether SHIP-2 is associated with the insulin resistance of diabetic db/db mice. The amount of SHIP-2 protein was elevated in quadriceps...
متن کاملLeptin receptor activation of SH2 domain containing protein tyrosine phosphatase 2 modulates Ob receptor signal transduction.
Leptin exerts its weight-reducing effects by binding to its receptor and activating signal transduction in hypothalamic neurons and other cell types. To identify the components of the leptin signal transduction pathway, an approach was developed in which bacterially expressed phosphorylated fragments of Ob receptor b (Ob-Rb) were used as affinity agents. Leptin binding to the Ob-Rb form of the ...
