mTOR inhibition sensitizes human hepatocellular carcinoma cells to resminostat

0 views | Jan 17 2018

Peng X et al. suggested that mTOR could be a primary resistance factor of resminostat. Targeted inhibition of mTOR may thus significantly sensitize HCC cells to resminostat. [Read the Full Post]

Sensitization of melanoma cells to alkylating agent-induced DNA damage and cell death via orchestrating oxidative stress and IKKβ inhibition

Tse AK et al. illustrated a new direction in nitrosourea treatment, and revealed that the combination of ROS-inducing IKKβ inhibitors with nitrosoureas can be potentially exploited for melanoma therapy. [Read the Full Post]

Targeting high Aurora kinases expression as an innovative therapy for hepatocellular carcinoma

813 views | Jan 16 2018

Liu F et al. provided a solid evidence for SNS-314 as a potential targeted therapy, and a proof-of-concept evidence for a possible combined therapy of SNS-314 plus Hippo pathway inhibitors on HCC. [Read the Full Post]

CDK4/6 Inhibition Controls Proliferation of Bladder Cancer and Transcription of RB1

414 views | Jan 15 2018

Sathe A et al. provided preclinical evidence that CDK4/6 inhibition is a potential therapeutic strategy for retinoblastoma positive bladder cancer that probably acts by negatively regulating retinoblastoma transcription. [Read the Full Post]

CK1δ kinase activity is modulated by protein kinase C α (PKCα)-mediated site-specific phosphorylation

1942 views | Jan 14 2018

Meng Z et al. contributed to a deeper understanding of cellular signal transduction networks thereby helping to form a basis for the development of future therapeutic concepts. [Read the Full Post]

Arsenic trioxide and all-trans-retinoic acid selectively exert synergistic cytotoxicity against FLT3-ITD AML cells via co-inhibition of FLT3 signaling pathways

893 views | Jan 13 2018

Wang LN et al. provided experimental evidence that supports further exploration of ATO/ATRA in FLT3-ITD AML in vivo and warrants a clinical evaluation of regimens comprising an ATO/ATRA combination. [Read the Full Post]
