Abstract Cancer cells may overcome growth factor dependence by deregulating oncogenic and/or tumor-suppressor pathways that affect their metabolism, or activating metabolic de novo with targeted mutations in critical enzymes. It is unknown whether human prostate tumors develop a similar response to different drivers particular event results its own reprogramming. Akt and Myc are arguably the most prevalent driving oncogenes cancer. Mass spectrometry–based metabolite profiling was performed...
Collagen I, the most abundant protein in humans, is ubiquitous solid tumors where it provides a rich source of exploitable metabolic fuel for cancer cells. While tumor cells were unable to exploit collagen directly, here we show they can usurp byproducts collagen-consuming tumor-associated stroma. Using genetically engineered mouse models, discovered that growth depends upon binding and uptake mediated by TEM8/ANTXR1 cell surface Tumor-associated stromal processed into glutamine, which was...
Abstract Histidine kinases are key regulators in the bacterial two-component systems that mediate cellular response to environmental changes. The vast majority of sensor histidine belong bifunctional HisKA family, displaying both kinase and phosphatase activities toward their substrates. molecular mechanisms regulating opposing these enzymes not well understood. Through a combined NMR crystallographic study on HK853 its regulator RR468 from Thermotoga maritima , here we report pH-mediated...
Many current genome editing technologies rely on the action of large serine integrases (LSIs) to insert gene-sized DNA sequences into genome. Bxb1 is most commonly used LSI for therapeutic efforts, including PASTE, PASSIGE and I-PGI. While demonstrated good activity in vitro cycling cells, non-dividing hepatocytes was significantly less efficient. Further, wild-type known have detectable off-target at cryptic genomic sites, which presents a potential safety risk development. To address these...
Nutrient deprivation triggers stringent response in bacteria, allowing rapid reallocation of resources from proliferation toward stress survival. Critical to this process is the accumulation/degradation (p)ppGpp regulated by RelA/SpoT homologues. While mammalian genomes encode MESH1, a homologue bacterial hydrolase SpoT, neither nor its synthetase has been identified cells. Therefore, function MESH1 remains mystery. Here, we report that human an efficient cytosolic NADPH phosphatase,...
Cancer cells undergo profound metabolic changes as a result of either abnormal signaling pathways or mutations occurring in genes encoding enzymes. A fundamental unanswered question is whether all oncogenic drivers harness similar response each event results its own specific program. Mass spectrometry‐based metabolomics was performed on immortalized human prostate epithelial transformed by the MYC and Akt oncogenes, transgenic mice driven same oncogenes under control prostate‐specific...
