Smooth muscle cell-specific Tgfbr1 deficiency promotes aortic aneurysm formation by stimulating multiple signaling events

310 views | May 24 2018

Yang P et al. indicated that loss of SMC-Tgfbr1 triggers multiple deleterious pathways, including abnormal TGFBR2, ERK, and AngII/AT1R signals that disrupt aortic wall homeostasis to cause aortic aneurysm formation. [Read the Full Post]

Regulation of glutamate transporter trafficking by Nedd4-2 in a Parkinson's disease model

0 views | May 24 2018

Carcinoma-associated fibroblasts affect sensitivity to oxaliplatin and 5FU in colorectal cancer cells

384 views | May 23 2018

Gonçalves-Ribeiro S et al. showed that STAT3 or P38 inhibition provides a promising strategy for overcoming microenvironment-mediated resistance. Conversely, pharmacologic AKT inhibition induces an antagonistic effect that relieves a cMET and STAT3-mediated compensatory feedback that might explain the failure of AKT inhibitors in the clinic so far.

Differences in MEK inhibitor efficacy in molecularly characterized low-grade serous ovarian cancer cell lines

378 views | May 23 2018

Fernández ML et al. showed the greatest anti-proliferative effects. This study serves as a basis for much needed future research on MEKi drug efficacy in LGSC. [Read the Full Post]

Androgen deprivation therapy sensitizes triple negative breast cancer cells to immune-mediated lysis through androgen receptor independent modulation of osteoprotegerin

440 views | May 22 2018

Kwilas AR et al. supported the consideration of AR inhibition therapy for the treatment of AR- TNBC, especially in combination with cancer immunotherapy, providing a potential novel therapeutic option for select patients. [Read the Full Post]

DNA-damage response gene GADD45A induces differentiation in hematopoietic stem cells without inhibiting cell cycle or survival

327 views | May 22 2018

Wingert S et al. indicated that genotoxic stress-induced GADD45A expression in HSCs prevents their fatal transformation by directing them into differentiation and thereby clearing them from the system. [Read the Full Post]

Unique roles of Akt1 and Akt2 in IGF-IR mediated lung tumorigenesis

1004 views | May 21 2018

Franks SE et al. suggested that compounds selectively targeting AKT1 may prove more effective than compounds that inhibit all three AKT isoforms at least in the treatment of lung adenocarcinoma. [Read the Full Post]

Epithelial-mesenchymal transition confers resistance to selective FGFR inhibitors in SNU-16 gastric cancer cells

0 views | May 21 2018

Grygielewicz P et al. provided experimental evidence that EMT-mediated resistance might emerge in gastric cancer patients following treatment with FGFR inhibitors, and mubritinib or AUY922 treatment may be an alternative therapeutic strategy for these patients. [Read the Full Post]

Mechanisms responsible for the synergistic antileukemic interactions between ATR inhibition and cytarabine in acute myeloid leukemia cells

707 views | May 20 2018

Ma J et al. provided insight into the mechanism of action underlying the synergistic antileukemic activity of ATR inhibition in combination with cytarabine in AML. [Read the Full Post]

PI3Kα isoform-dependent activation of RhoA regulates Wnt5a-induced osteosarcoma cell migration

3087 views | May 20 2018

Zhang A et al. demonstrated that RhoA acts as the downstream of PI3K/Akt signaling (specific PI3Kα, Akt1 and Akt2 isoforms) and mediated Wnt5a-induced the migration of osteosarcoma cells. [Read the Full Post]

Pharmacological Inhibition of PERK Attenuates Early Brain Injury After Subarachnoid Hemorrhage in Rats Through the Activation of Akt

578 views | May 19 2018

Yan F et al. found that PERK might serve as a promising target for future therapeutic intervention. [Read the Full Post]

Resveratrol Attenuates Aβ25-35 Caused Neurotoxicity by Inducing Autophagy Through the TyrRS-PARP1-SIRT1 Signaling Pathway.

405 views | May 19 2018

Deng H et al. found that RSV attenuated neurotoxicity caused by Aβ25-35 through inducing autophagy in PC12 cells, and the autophagy was partially mediated via activation of the TyrRS-PARP1-SIRT1 signaling pathway. [Read the Full Post]

Mitotic entry: Non-genetic heterogeneity exposes the requirement for Plk1

440 views | May 18 2018

Aspinall CF et al. discussed the implications for developing Plk1 inhibitors as chemotherapy agents and research tools. [Read the Full Post]

Gli1-Mediated Regulation of Sox2 Facilitates Self-Renewal of Stem-Like Cells and Confers Resistance to EGFR Inhibitors in Non-Small Cell Lung Cancer

605 views | May 18 2018

Bora-Singhal N et al. demonstrated a cooperative functioning of the EGFR signaling and Hedgehog pathways in governing the stem-like functions of NSCLC cancer stem cells and presents a novel therapeutic strategy to combat NSCLC harboring EGFR mutations. [Read the Full Post]

Long non-coding RNA NKILA inhibits migration and invasion of non-small cell lung cancer via NF-κB/Snail pathway

1599 views | May 17 2018

Lu Z et al. found that the expression of NKILA was downregulated in tumor tissues of NSCLC, which improved the metastasis of NSCLC patients. In vitro studies further clarified that the expression of NKILA was regulated through classical TGF-β signal pathway, which subsequently inhibited migration and invasion of NSCLC cells through interfering NF-κB/Snail signal pathway in NSCLC cells.
