TAp73 promotes anabolism
Metabolic adaptation has emerged as a hallmark of cancer and a promising therapeutic target, as rapidly proliferating cancer cells adapt their metabolism increasing nutrient uptake and reorganizing metabolic fluxes to support biosynthesis. The transcription factor p73 belongs to the p53-family and regulates tumorigenesis via its two N-terminal isoforms, with (TAp73) or without (ΔNp73) a transac...
متن کاملMechanisms of bone anabolism regulated by statins
Osteoporosis is a common disease in the elderly population. The progress of this disease results in the reduction of bone mass and can increase the incidence of fractures. Drugs presently used clinically can block the aggravation of this disease. However, these drugs cannot increase the bone mass and may result in certain side effects. Statins, also known as HMG-CoA (3-hydroxy-3-methylglutaryl-...
متن کاملGating the mechanical channel Piezo1
Piezo1 is a eukaryotic cation-selective mechanosensitive ion channel. To understand channel function in vivo, we first need to analyze and compare the response in the whole cell and the patch. In patches, Piezo1 inactivates and the current is fit well by a 3-state model with a single pressure-dependent rate. However, repeated stimulation led to an irreversible loss of inactivation. Remarkably, ...
متن کاملSpinal nociceptive transmission by mechanical stimulation of bone marrow
BACKGROUND Since bone marrow receives innervation from A-delta and C-fibers and since an increase in intramedullary pressure in bone marrow may induce acute pain in orthopedic patients during surgery and chronic pain in patients with bone marrow edema, skeletal pain may partly originate from bone marrow. Intraosseous lesions, such as osteomyelitis and bone cancer, are also known to produce cuta...
متن کاملIdentification of biomarkers for bone union promoted by mechanical stimulation.
At present, the identity of the proteins that participate in mechanical stimulation during the fracture healing process is not known. Here, we screened for and identified 299 proteins that are expressed in various stages of mechanically stimulated fracture healing. Among these biomarkers, 54 proteins were differentially expressed during all three recovery time points. Gene ontology (GO) analysi...
