Goebel S et al. showed qPCR associated higher sensitivity and short duration of the assay time, this novel cell based assay will be very useful for confirming the activity of antivirals against ZIKV. [Read the Full Post]

Retinoic acid and TGF-β signalling cooperate to overcome MYCN-induced retinoid resistance

1905 views | Oct 15 2018

Duffy DJ et al. provided a powerful precision oncology tool for identifying the driving signalling networks for malignancies not primarily driven by somatic mutations, such as paediatric cancers. By applying global omics approaches to the signalling networks regulating neuroblastoma differentiation and stemness, we have determined the pathways involved in the MYCN-mediated retinoid resistance, with TGF-β signalling being a key regulator. These findings revealed a number of combination treatments likely to improve clinical response to retinoid therapy, including co-treatment with retinoids and KGN, which may prove valuable in the treatment of high-risk MYCN-amplified neuroblastoma.

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

0 views | Oct 14 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]

Acquired resistance to combination treatment through loss of synergy with MEK and PI3K inhibitors in colorectal cancer

0 views | Oct 14 2018

Bhattacharya B et al. highlight that AQR to combination treatment may develop through alternative mechanisms to those of single agent treatment, including a change in drug interaction. [Read the Full Post]

Romidepsin induces G2/M phase arrest via Erk/cdc25C/cdc2/cyclinB pathway and apoptosis induction through JNK/c-Jun/caspase3 pathway in hepatocellular carcinoma cells

Luo F et al. suggested that atorvastatin/metformin combination therapy may achieve additional anti-atherosclerotic benefits likely through increasing cholesterol efflux in macrophages. [Read the Full Post]

Resistance to RET-Inhibition in RET-Rearranged NSCLC Is Mediated By Reactivation of RAS/MAPK Signaling

1701 views | Oct 12 2018

Nelson-Taylor SK et al. demonstrated that resistance to ponatinib in RET-rearranged lung adenocarcinoma is mediated by bypass signaling mechanisms that result in restored RAS/MAPK activation. [Read the Full Post]

Epigenetic repression of miR-375 is the dominant mechanism for constitutive activation of the PDPK1/RPS6KA3 signalling axis in multiple myeloma.

924 views | Oct 12 2018

Tatekawa S et al. showed the universal involvement of overlapping epigenetic dysregulation for abnormal miR-375 repression in MM, which is likely to contribute to myelomagenesis and to subsequent myeloma progression by activating oncogenic signalling pathways. [Read the Full Post]

Activation of Wnt/β-catenin signalling is required for TGF-β/Smad2/3 signalling during myofibroblast proliferation

780 views | Oct 12 2018

Xu L et al. found that a major outcome of this study is improved insight into the mechanisms by which epithelial and mesenchymal cells activated by TGFβ1-smad2/3 signalling through Wnt/β-catenin contribute to lung fibrosis. [Read the Full Post]

Tumor Necrosis Factor Inhibits Spread of Hepatitis C Virus Among Liver Cells, Independent From Interferons

863 views | Oct 10 2018

Laidlaw SM et al. found TNF to have antiviral effects independently of, as well as in combination with, IFNs. TNF inhibits HCV infection despite increased HCV envelope glycoprotein-mediated infection of liver cells. These findings contradict those from other studies, which have reported that TNF blocks signal transduction in response to IFNs. The destructive inflammatory effects of TNF must be considered along with its antiviral effects. [Read the Full Post]
