PIM kinase inhibitor AZD1208 for treatment of MYC-driven prostate cancer

84 views | Apr 14 2019

Kirschner AN et al. showed that PIM inhibition is a potential treatment for MYC-driven prostate cancers including CRPC, and its effectiveness may be enhanced by activators of the p53 pathway, such as radiation. [Read the Full Post]

Control of translational activation by PIM kinase in activated B-cell diffuse large B-cell lymphoma confers sensitivity to inhibition by PIM447

Peters TL et al. characterized recurrent PIM1 protein-coding mutations found in DLBCL clinical samples and find most preserve the wild-type protein's ability to protect cells from apoptosis but do not bypass activity of PIM447. Pan-PIM inhibition therefore may have an important role to play in the therapy of selected ABC-DLBCL cases. [Read the Full Post]

The mechanism of resistance to JAK2 inhibitor in myeloproliferative neoplasms patients

Winter et al. identified the underlying mechanism of the emerging JAK2 inhibitor therapy resistance in MPNs patients, and found the RAS and pathways mediated by AKT and ERK contribute to the resistance. [Read the Full Post]

Roles of PIM serine/threonine kinases in cancers

The Pim family of Ser/Thr kinases has been first identified in murine Moloney leukemia virus induced lymphomas, and is composed of three isoforms, Pim-1, Pim-2 and Pim-3. The following studies show that Pims are constitutively activated in many cancers. Of which, Pim-1 and Pim-2 were found to show the elevated levels mostly in hematologic malignancies and prostate cancer, while increased Pim-3 expression was mainly observed in different solid tumors.

These findings support the idea that inhibiting Pim kinases, in combination with a chemotherapeutic agent, could play an important role in prostate cancer treatment by targeting the clinical problem of chemoresistance. [Read the Full Post]

Consistent with a decline in new RNA synthesis, MCL-1 transcript levels were decreased after treatment with SGI-1776. These data suggest that SGI-1776 induces apoptosis in CLL and that the mechanism involves Mcl-1 reduction. [Read the Full Post]

Pim-1 is able to phosphorylate different targets, most of which are involved in cell cycle progression or apoptosis. Pim-1 expression can be induced by several external stimuli in particular by a number of cytokines relevant in the immune system, which led to the labeling of Pim-1 as a "booster" for the immune response.
