MetabolomicsCPT2 inhibition activates selective autophagy by enhancing glycerophospholipid biosynthesis in colorectal cancer

Metabolic reprogramming is one of the hallmark events in colorectal cancer (CRC).  Tumor cells adapt to microenvironmental changes by regulating energy and biomaterial metabolism. This study identified abnormal lipid accumulation and significant downregulation of fatty acid metabolism in CRC...

MetabolomicsMTCH2 modulates CPT1 activity to regulate lipid metabolism of adipocytes

To understand the molecular changes that underwrite enhanced mitochondrial respiration upon MTCH2 knockdown, we performed lipidomics profiling in hMADs adipocytes.

MetabolomicsTEX44 CPT1B Axis Regulates Mitochondrial Sheath Assembly and Fatty Acid Oxidation in Sperm

Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673800 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals...

Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals, all ...

ProteomicsCombined cysteine oxidation (C6-CPT/CysPAT) proteomics and phosphoproteomics of pervanadate-treated of HEK293T cells
HEK293T cells were treated with pervanadate for 0, 5 or 15 minutes to evaluate the effects on the phosphorylation and cysteine oxidation status across the proteome. Samples were labelled withTMT 18plex and C6-CPT/CysPAT labelling was used to allow the simultaneous enrichment of both the phosphoprote...

TranscriptomicsTranscription profiling of Zea mays embryos under camptothecin (CPT) treatment.
Camptothecin (CPT) is a plant alkaloid that specifically binds topoisomerase I (Topo I) inhibiting its activity and inducing double stranded breaks in the DNA, activating the genotoxic cell responses, and ultimately, it might trigger programmed cell death (PCD). We used microarrays to detail the cha...

TranscriptomicsImmune cell subsets and their gene expression profiles from human PBMC isolated by Vacutainer Cell Preparation Tube and standard density gradient
High quality genetic material is an essential pre-requisite when analyzing gene expression using microarray technology. Peripheral blood mononuclear cells (PBMC) are frequently used for genomic analyses, but several factors can affect the integrity of nucleic acids prior to their extraction, includi...

TranscriptomicsTranscription profiling of mouse S49 cells to study the global impact of cAMP and protein kinase A on gene expression
Although a substantial number of hormones and drugs increase cellular cAMP levels, the global impact of cAMP and its major effector mechanism, protein kinase A (PKA), on gene expression is not known. Here we show that treatment of wild-type S49 lymphoma cells for 24 h with 8-(4-chlorophenylthio)-cAM...

TranscriptomicsTranscription profiling of topoisomerase I inhibitor irinotecan (CPT-11) sensitive, resistant, and reverted human neuroblastomas
We have established a neuroblastoma model resistant in vivo to the topoisomerase I inhibitor irinotecan (CPT-11, Camptothecin-11, CAMPTOSAR®) in order to study resistance to these agents acquired in a therapeutic setting. Common mechanisms of resistance were not involved in this model and we thus ex...

TranscriptomicsGenome-wide analysis of novel splice variants induced by topoisomerase I poisoning shows preferential occurrence in genes encoding splicing factors
Topoisomerase I (Top1) relaxes both positive and negative supercoilings by producing transient Top1 cleavage complexes (Top1cc). Several studies have suggested the implication of Top1 in splicing. Here, we tested the implication of Top1cc in splicing at the global genome level in human carcinoma cel...
