Prolonged mitotic arrest induces a caspase-dependent DNA damage response at telomeres that determines cell survival

1709 views | Nov 23 2016

Hain KO et al. demonstrated that mitotic stress is characterised by the sub-apoptotic activation of a classical caspase pathway, which promotes telomere deprotection, activates DNA damage signalling, and determines cell fate in response to a prolonged delay in mitosis. [Read the Full Post]

Cannabinoid receptor-2 stimulation suppresses neuroinflammation by regulating microglial M1/M2 polarization through the cAMP/PKA pathway in an experimental GMH rat model

Inhibition of Extracellular Calcium Influx Results in Enhanced IL-12 Production in LPS-Treated Murine Macrophages by Downregulation of the CaMKKb-AMPK-SIRT1 Signaling Pathway

391 views | Nov 23 2016

Liu X et al.’s study demonstrates a new role of transmembrane calcium mobilization in immunity modulation such that inhibition of calcium influx leads to impaired activation of CaMKKβ-AMPK-SIRT1 signaling pathway which lifts restriction on NF-κB activation and results in enhanced IL-12 production.

Tetrandrine has anti-adipogenic effect on 3T3-L1 preadipocytes through the reduced expression and/or phosphorylation levels of C/EBP-α, PPAR-γ, FAS, perilipin A, and STAT-3

1194 views | Nov 22 2016

Jang BC et al. showed that tetrandrine has strong anti-adipogenic effect on 3T3-L1 preadipocytes and the effect is largely attributable to the reduced expression and/or phosphorylation levels of C/EBP-α, PPAR-γ, FAS, perilipin A, and STAT-3. [Read the Full Post]

tRNA modification profiles of the fast-proliferating cancer cells

1697 views | Nov 22 2016

Dong C et al.'s results indicated that tRNA is a actively regulated RNA species in the fast-proliferating cancer cells, and suggest that they may play a more active role in biological process than expected. [Read the Full Post]

Diverse, Biologically Relevant, and Targetable Gene Rearrangements in Triple-Negative Breast Cancer and Other Malignancies

2134 views | Nov 21 2016

Shaver TM et al. identified highlight the importance of considering noncoding gene rearrangement partners, and the targetable gene fusions identified in TNBC demonstrate the need to advance gene fusion detection for molecularly heterogeneous cancers. [Read the Full Post]

MEK inhibitor CI-1040 induces apoptosis in acute myeloid leukemia cells in vitro

1007 views | Nov 21 2016

Wei CR et al. demonstrated that CI-1040 induce apoptosis of U-937 cells and might be a new therapeutic option for the treatment of AML. [Read the Full Post]

Nucleoside Inhibitors of Zika Virus

1054 views | Nov 20 2016

Antiviral activity was identified when 2'-C-methylated nucleosides were tested, suggesting that these compounds might represent promising lead candidates for further development of specific antivirals against ZIKV. [Read the Full Post]

The Mitogen-Activated Protein Kinase Pathway Facilitates Resistance to the Src Inhibitor Dasatinib in Thyroid Cancer

1141 views | Nov 18 2016

Beadnell TC et al. demonstrated that up-front combined inhibition with dasatinib and MEK1/2 or ERK1/2 inhibitors drives synergistic inhibition of growth and induction of apoptosis, indicating that combined inhibition may overcome mechanisms of survival in response to single-agent inhibition.
