MetabolomicsFirst-in-class MKK4 inhibitors enhance liver regeneration and prevent liver failure

Diminished hepatocyte regeneration is a key feature of acute and chronic liver diseases and after extended liver resections, resulting in the inability to maintain or restore a sufficient functional liver mass. Therapies to restore hepatocyte regeneration are lacking, making liver transplantation...

MetabolomicsDissection of two routes to naïve pluripotency using different kinase inhibitors
Embryonic stem cells (ESCs) can be maintained in the naïve state through inhibition of Mek1/2 and Gsk3 (2i). A relevant effect of 2i is the inhibition of Cdk8/19, which are negative regulators of the Mediator complex, responsible for the activity of enhancers. Inhibition of Cdk8/19 (Cdk8/19i) stimul...

TranscriptomicsIdentification of direct transcriptional targets of V600EBRAF/MEK in melanoma
A375P melanoma cells were treated with 1uM of the MEK inhibitor PD184352 or 0.4uM of the V600EBRAF inhibitor PLX4720 for 2hr, 6hr and 24hrs. DMSO treatment for 2hr, 6hr and 24hrs serves as the negative control Triplicate experiments were performed for DMSO, PD184352 and PLX4720 treatment at 3 timepo...

TranscriptomicsHepG2-MEK Inhibition with PD98059
Transcripts (mRNA) during amino acid limitation after MEK was inhibited were analyzed. HepG2 cells were pretreated with MEK inhibitor, PD98059 for 1 hour, then incubated in complete medium and a medium depleted for Histidine for 8 hours. For Inhibitor treated cells, PD98059 was included in the mediu...

TranscriptomicsMEK inhibition exhibits efficacy in human and mouse neurofibromatosis tumors, despite transcriptional feedback onto ERK.
Neurofibromatosis Type 1 (NF1) patients develop benign neurofibromas and malignant peripheral nerve sheath tumors (MPNST). These incurable peripheral nerve tumors result from loss of NF1 tumor suppressor gene function, causing hyperactive Ras signaling. Activated Ras controls numerous downstream eff...

TranscriptomicsHuman monocyte-derived dendritic cells treated with U0126 or SB203580
Identification of MEK-ERK or p38MAPK dependent genes in human monocyte derived dendritic cells. Dendritic cells (DC) promote tolerance or immunity depending on their maturation state. Previous studies have revealed that DC maturation is enhanced or accelerated upon MEK-ERK signaling pathway inhibiti...

TranscriptomicsSuppression of IFN-induced transcription underlies IFN defects generated by activated Ras/MEK in human cancer cells
Certain oncolytic viruses exploit activated Ras signalling in order to replicate in cancer cells. Constitutive activation of the Ras/MEK pathway is known to suppress the effectiveness of the interferon (IFN) antiviral response, which may contribute to Ras-dependent viral oncolysis. Here, we identifi...

ProteomicsTargeting β-catenin overcomes resistance to MEK inhibitor in PIK3CA mutant colon cancer
Mitogen-activated protein kinases (MEK 1/2) are central components of the RAS signaling pathway and attractive targets for cancer therapy. However, PIK3CA mutation, which commonly co-occurs with KRAS mutation, offered resistance to MEK inhibitor through activation of PI3K-AKT signaling. We identifie...

TranscriptomicsComparison between HuT78 parental and romidpepsin-selected cell lines
Gene expression values were determined for HuT78 parental cells and cells selected with romidpesin in the presence of P-glycoprotein inhibitors. HuT78 DpVp35 cells are maintained in 35 ng/ml romidepsin with 2.5 µg/ml verapamil and HuT78 DpP100 cells are maintained in 100 ng/ml romidepsin with 1 µM v...
