DW09849, a selective phosphatidylinositol 3-kinase (PI3K) inhibitor, prevents PI3K signaling and preferentially inhibits proliferation of cells containing the oncogenic mutation p110α (H1047R).

231 views | Sep 22 2018

Liu JL et al. suggested that DW series compounds, especially DW09849, selectively targeting PI3Kα with less off-target effects than PIK-75, provide new clues for the design and discovery of new specific PI3Kα inhibitors for cancer therapy. [Read the Full Post]

Short-term high-fat feeding induces islet macrophage infiltration and β-cell replication independently of insulin resistance in mice

223 views | Sep 21 2018

Woodland DC et al. suggested the existence of MΦ-mediated mechanisms in β-cell replication that are independent of insulin resistance. [Read the Full Post]
