Xie S et al. showed that CDK inhibitor LS-007 potently inhibits the established human AL cell lines and primary AL blasts, and it also shows remarkable synergy with Bcl-2 inhibitor ABT-199. [Read the Full Post]

Weak binding to E3 ubiquitin ligase c-Cbl increases EGFRvA protein stability

1116 views | Dec 04 2017

Song F et al. found that EGFRvA is more stable than EGFR because of its decreased binding to c-Cbl. [Read the Full Post]

High efficacy of the BCL-2 inhibitor ABT199 (venetoclax) in BCL-2 high-expressing neuroblastoma cell lines and xenografts and rational for combination with MCL-1 inhibition

1028 views | Dec 03 2017

Bate-Eya LT et al. suggested that neuroblastoma patients with high BCL-2 and BIM/BCL-2 complex levels might benefit from combination treatment with ABT199 and compounds that inhibit MCL-1 expression. [Read the Full Post]

Arsenite suppresses angiogenesis of vascular endothelial cells mediated by Platelet Derived Growth Factor Receptor-beta

1344 views | Dec 03 2017

Wang X et al. concluded that arsenite suppressed the angiogenesis of the vascular endothelial cells, that this effect is mediated by PDGFR-beta, and postulate that it might contribute to the injuries of blood vessel in arsenism. [Read the Full Post]

CK2α' Drives Lung Cancer Metastasis by Targeting BRMS1 Nuclear Export and Degradation

0 views | Dec 02 2017

Liu Y et al. identified a therapeutically exploitable posttranslational mechanism by which CK2α-mediated degradation of BRMS1 promotes metastases in lung cancer. [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

1515 views | Dec 02 2017

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 HSP90 inhibitor, NVP-AUY922, sensitizes KRAS-mutant non-small cell lung cancer with intrinsic resistance to MEK inhibitor, trametinib

0 views | Dec 01 2017

Park KS et al. showed that dual inhibition of the HSP90 and MEK signaling pathways with sub-therapeutic doses may represent a potent therapeutic strategy to treat KRAS-mutant NSCLC with intrinsic resistance to MEK inhibition and to resolve the toxicity observed upon dual inhibition of AKT and MEK at therapeutic doses in clinical trials.

Icaritin activates JNK-dependent mPTP necrosis pathway in colorectal cancer cells

0 views | Dec 01 2017

Zhou C et al. showed that ICT exerts potent inhibitory effect against CRC cells in vitro and in vivo. JNK-dependent mPTP necrosis pathway could be key mechanism responsible for ICT's actions. [Read the Full Post]

Autophagy prevention sensitizes AKTi-1/2-induced anti-hepatocellular carcinoma cell activity in vitro and in vivo

0 views | Nov 30 2017

Zhang Q et al. demonstrated that autophagy activation serves as a main resistance factor of AKTi-1/2 in HCC cells. Autophagy prevention therefore sensitizes AKTi-1/2-induced anti-HCC activity in vitro and in vivo. [Read the Full Post]

HSP90 activity is required for MLKL oligomerisation and membrane translocation and the induction of necroptotic cell death

1857 views | Nov 29 2017

Jacobsen AV et al. implicated HSP90 as a modulator of necroptosis at the level of MLKL, a function that complements HSP90's previously demonstrated modulation of the upstream necroptosis effector kinases, RIPK1 and RIPK3. [Read the Full Post]

Autophagy prevention sensitizes AKTi-1/2-induced anti-hepatocellular carcinoma cell activity in vitro and in vivo

1204 views | Nov 29 2017

Zhang Q et al. demonstrate that autophagy activation serves as a main resistance factor of AKTi-1/2 in HCC cells. [Read the Full Post]

Integrative Network Analysis Combined with Quantitative Phosphoproteomics Reveals Transforming Growth Factor-beta Receptor type-2 (TGFBR2) as a Novel Regulator of Glioblastoma Stem Cell Properties

1242 views | Nov 28 2017

Narushima Y et al. indicated that transforming growth factor-β receptor type-2 could play an important role as a novel cell fate determinant in glioblastoma stem cell regulation. [Read the Full Post]

Activation of anaphase-promoting complex by p53 induces a state of dormancy in cancer cells against chemotherapeutic stress

1506 views | Nov 28 2017

Dai Y et al. provided a mechanism to unravel cancer cell dormancy and reactivation of the cancer cell population. [Read the Full Post]

The BET inhibitor OTX015 reactivates latent HIV-1 through P-TEFb

982 views | Nov 27 2017

Lu P et al. suggested that the BET inhibitor OTX015 may be a candidate for anti-HIV-1-latency therapies. [Read the Full Post]

Complex Roles of Annexin A2 in Host Blood-Brain Barrier Invasion by Cryptococcus neoformans

1299 views | Nov 27 2017

Fang W et al. indicated that AnxA2 played complex roles in traversal of C. neoformans across host BMECs, which might be dependent on downstream cofilin to inhibit fungal adhesion but rely on its partner S100A10 to promote cryptococcal transcytosis. [Read the Full Post]

MicroRNA-520e suppresses non-small-cell lung cancer cell growth by targeting Zbtb7a-mediated Wnt signaling pathway

1471 views | Nov 26 2017

Zhijun Z et al. indicated that overexpressing miR-520e is involved in regulating the NSCLC cell growth, invasion and migration by targeting Zbtb7a partly depending on Wnt signaling. [Read the Full Post]

Kinome Profiling Identifies Druggable Targets for Novel Human Cytomegalovirus (HCMV) Antivirals

917 views | Nov 26 2017

Arend KC et al. showed the utility of MIB-MS kinome profiling for identifying existing kinase inhibitors that can potentially be repurposed as novel antiviral drugs. [Read the Full Post]
