WISP1 overexpression promotes proliferation and migration of human vascular smooth muscle cells via AKT signaling pathway

0 views | Jul 14 2017

Lu S et al. demonstrated that Akt signaling pathway mediates WISP1-induced migration and proliferation of human VSMCs, suggesting that WISP1 may act as a novel potential therapeutic target for vascular restenosis. [Read the Full Post]

Metalloproteinase-9 contributes to endothelial dysfunction in atherosclerosis via protease activated receptor-1

765 views | Jul 13 2017

Florence JM et al. demonstrated that metalloproteinase-9 could activate endothelial cells and induce their apoptosis via cleavage of protease activated receptor-1. In summary, better understanding of metalloproteinase-9's pathogenic capabilities as well as novel signaling pathways involved may lead to development of treatments which may provide additional benefits to atherosclerosis patients with a history of second hand smoke exposure.

Identification of DYRK1B as a substrate of ERK1/2 and characterisation of the kinase activity of DYRK1B mutants from cancer and metabolic syndrome

744 views | Jul 13 2017

Ashford AL et al. showed that DYRK1B is a novel ERK2 substrate, uncovering new links between two kinases involved in cell fate decisions. Finally, we show that DYRK1B mutants that have recently been described in cancer and metabolic syndrome exhibit normal or reduced intrinsic kinase activity. [Read the Full Post]

Tris (1, 3-dichloro-2-propyl) phosphate induces apoptosis and autophagy in SH-SY5Y cells: Involvement of ROS-mediated AMPK/mTOR/ULK1 pathways

1118 views | Jul 12 2017

Li R et al. provided the first evidence that TDCIPP promotes apoptosis and autophagy simultaneously and that this process involves the ROS-mediated AMPK/mTOR/ULK1 pathways. Lastly, the induction of autophagy is a protective mechanism against TDCIPP-induced apoptosis. [Read the Full Post]

0 views | Jul 11 2017

Srivastava VK et al. suggested that Mn acts, at least in part, through the IGF-1/Akt/mTOR pathway to influence prepubertal kisspeptin and LHRH. [Read the Full Post]

Persistent GP130/STAT3 Signaling Contributes to the Resistance of Doxorubicin, Cisplatin, and MEK Inhibitor in Human Rhabdomyosarcoma Cells

1541 views | Jul 10 2017

Wu X et al. demonstrated that GP130/STAT3 signaling contributes to the resistance of these drugs in rhabdomyosarcoma cells. They also suggested a potentially novel cancer therapeutic strategy using the combination of inhibitors of GP130/STAT3 signaling with doxorubicin, cisplatin, or AZD6244 for rhabdomyosarcoma treatments.

HBXIP, a binding protein of HBx, regulates maintenance of the G2/M phase checkpoint induced by DNA damage and enhances sensitivity to doxorubicin-induced cytotoxicity

1465 views | Jul 10 2017

Fei HR et al. suggested that HBXIP can function as a mediator protein for DNA damage response signals to activate the G2/M checkpoint to maintain genome integrity and prevent cell death. [Read the Full Post]

Ras oncogene-independent activation of RALB signaling is a targetable mechanism of escape from NRAS(V12) oncogene addiction in acute myeloid leukemia

853 views | Jul 09 2017

Pomeroy EJ et al. demonstrated that Ras oncogene-independent activation of RALB signaling is a therapeutically targetable mechanism of escape from NRAS oncogene addiction in AML. [Read the Full Post]

A cyclin-dependent kinase inhibitor, dinaciclib in preclinical treatment models of thyroid cancer

1007 views | Jul 09 2017

Lin SF et al. findings support dinaciclib as a potential drug for further studies in clinical trials for the treatment of patients with refractory thyroid cancer. [Read the Full Post]

WNT/β-catenin signaling promotes VSMCs to osteogenic transdifferentiation and calcification through directly modulating Runx2 gene expression.

0 views | Jul 08 2017

Cai T et al. suggested that high-phosphate may activate WNT/β-catenin signaling through different pathways, and the activated WNT/β-catenin signaling, through direct downstream target Runx2, could play an important role in promoting VOT and AMC. [Read the Full Post]

Inhibition of mTOR Signaling Pathway Delays Follicle Formation in Mice

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

809 views | Jul 05 2017

Park KS et al. showed that intrinsic resistance to MEK inhibition occurred via high AKT expression by PI3K activation as a bypass pathway. The HSP90 inhibitor AUY922 suppressed PI3K-AKT-mTOR and RAF-MEK-ERK, and rendered cells sensitive to trametinib (GSK1120212). Synergy from the combination of the two drugs was observed in only sub-therapeutic concentrations of either drug. 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.
