MetabolomicsSerine synthesis pathway enzyme PHGDH is critical for muscle cell biomass, anabolic metabolism and mTORC1 signaling

Cells use glycolytic intermediates for anabolism e.g., via the serine synthesis and pentose phosphate pathways. However, we still understand poorly how these metabolic pathways contribute to skeletal muscle cell biomass generation. The first aim of this study was therefore to identify enzymes tha...

TranscriptomicsSmall molecule activation of PKM in cancer cells induces serine auxotrophy
Proliferating tumor cells use aerobic glycolysis to support their high metabolic demands. Paradoxically, increased glycolysis is often accompanied by expression of the lower activity PKM isoform, effectively constraining lower glycolysis. Here, we report the discovery of novel PKM activators with ...

TranscriptomicsAmino acid deprivation due to overexpression of UCP1 in skeletal muscle: signalling via FGF-21
Recent studies on mouse and human skeletal muscle (SM) demonstrated the important link between mitochondrial function and the cellular metabolic adaptation. To identify key compensatory molecular mechanisms in response to chronic mitochondrial distress, we analyzed mice with ectopic SM respiratory u...

TranscriptomicsExpression data from brain tissue of Rattus norvegicus treated with D-Serine
d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxi...

TranscriptomicsExpression in HepG2 cells with overexpression of TMPRSS6 or its mutant version.
TMPRSS6 is a type II transmembrane serine protease and is revealed by our work to be part of a low-iron sensing pathway. When animal gets iron deficient, TMPRSS6 is required to shut off hepcidin gene, so as to allow iron to be uptaken from GI tract. The mutant mouse, which was generated by ENU mutag...

TranscriptomicsAssessment of MEK-ERK pathway targeting by BRAF, NRAS and KRAS gene mutations in plasma cell dyscrasias [U266 human myeloma cell line]
Multiple myeloma (MM) is a malignant disorder characterized by the clonal proliferation of plasma cells (PCs) in the bone marrow (BM). The genetic background and clinical course of the disease are largely heterogeneous, and MM pathophysiology ranges from the premalignant condition of monoclonal gamm...

TranscriptomicsTargeting the MTOR-AKT pathway in DLBCL
The mTOR (mammalian Target of Rapamycin) pathway is constitutively activated in Diffuse Large B-Cell Lymphoma (DLBCL). mTOR inhibition has been shown to have clinical activity in patients with DLBCL, although overall response rates remain low. We therefore evaluated differences in the transcriptome...

TranscriptomicsPathways leading to phosphorylation of p450c17 and to the post-translational regulation of androgen biosynthesis
Cytochrome P450c17 (P450c17) is the single enzyme that catalyzes steroid 17alpha-hydroxylase and 17,20 lyase activities and hence is the crucial decision-making step that determines the class of steroid made in a steroidogenic cell. Although both activities are catalyzed on a single active site, the...
