The ubiquitin ligase F-box and WD repeat domain-containing 7 (FBXW7) is recognized as a tumor suppressor in many cancer types due to its ability to promote the degradation of numerous oncogenic target proteins.
This article was published in the following journal.
Name: Journal of hepatology
FBXW7 is a tumor suppressive E3 ligase, whereas RAS-ERK and mechanistic target of rapamycin kinase (mTORC1) are two major oncogenic pathways. Whether and how FBXW7 regulates these two oncogenic pathw...
Rho GTPases control both the actin cytoskeleton and adherens junction stability and are recognized as essential regulators of endothelial barrier function. Rho GTPases act as molecular switches and ar...
FBXW7, a classic tumor suppressor, is a substrate recognition subunit of the Skp1-cullin-F-box (SCF) ubiquitin ligase that targets oncoproteins for ubiquitination and degradation. We recently found th...
Dormant cancer cells known as disseminated tumor cells (DTCs) are often present in bone marrow of breast cancer patients. These DTCs are thought to be responsible for the incurable recurrence of breas...
Previous studies in several model organisms have revealed that members of the Forkhead (Fkh) transcription factor family have multiple functions. Drosophila Jumeau (Jumu), a member of this family, par...
The purpose of this study is to delineate the effects of preoperative oral carbohydrate on immediate postoperative insulin resistance (PIR) in patients undergoing elective open colorectal ...
Growth hormone (GH) induces fat metabolism. The mechanisms underlying the fat metabolizing effects of GH remain elusive. However, it is known that insulin suppresses fat metabolism, and GH...
This protocol addresses: 1) How gene expression changes in bone cells are affected by aging? 2) Is aging associated with decreased signaling between bone cells? 3) How does treatment with ...
Stress and cues reminiscent of cocaine use promote craving and relapse in cocaine dependent individuals. In addition, there appears to be gender differences in determinants of relapse to ...
Resveratrol is purported to possess cancer preventive activity, especially for colon cancer, though its mechanisms of action are not well defined. Resveratrol is found in the skin of grape...
A major class of calcium activated potassium channels whose members are voltage-dependent. MaxiK channels are activated by either membrane depolarization or an increase in intracellular Ca(2+). They are key regulators of calcium and electrical signaling in a variety of tissues.
Intracellular signaling protein kinases that play a signaling role in the regulation of cellular energy metabolism. Their activity largely depends upon the concentration of cellular AMP which is increased under conditions of low energy or metabolic stress. AMP-activated protein kinases modify enzymes involved in LIPID METABOLISM, which in turn provide substrates needed to convert AMP into ATP.
An intracellular signaling system involving the MAP kinase cascades (three-membered protein kinase cascades). Various upstream activators, which act in response to extracellular stimuli, trigger the cascades by activating the first member of a cascade, MAP KINASE KINASE KINASES; (MAPKKKs). Activated MAPKKKs phosphorylate MITOGEN-ACTIVATED PROTEIN KINASE KINASES which in turn phosphorylate the MITOGEN-ACTIVATED PROTEIN KINASES; (MAPKs). The MAPKs then act on various downstream targets to affect gene expression. In mammals, there are several distinct MAP kinase pathways including the ERK (extracellular signal-regulated kinase) pathway, the SAPK/JNK (stress-activated protein kinase/c-jun kinase) pathway, and the p38 kinase pathway. There is some sharing of components among the pathways depending on which stimulus originates activation of the cascade.
Non-visual system arrestins that negatively regulate G-PROTEIN-COUPLED RECEPTORS (GPCRs) and may also function independently of GPCR signaling. They bind and recruit many different signaling factors, including MITOGEN-ACTIVATED PROTEIN KINASES; SRC-FAMILY-KINASES; and FILAMIN to GPCRs and may recognize different phosphorylation states of the receptors to determine the specificity of the cellular response to signaling.
An intracellular signaling adaptor protein that plays a role in TOLL-LIKE RECEPTOR and INTERLEUKIN 1 RECEPTORS signal transduction. It forms a signaling complex with the activated cell surface receptors and members of the IRAK KINASES.
