The reciprocal stability of FOXO1 and IRS2 creates a regulatory circuit that controls insulin signaling.
The transcription factor FoxO1 links the phosphatidylinositol 3-kinase (PI 3-kinase) --> Akt cascade to gene expression that regulates cell growth, survival, and metabolism. The receptors for insulin and IGFs factors are linked to this pathway through tyrosine phosphorylation of insulin receptor substrates-Irs1, 2, 3, and 4. However, it is unclear why Irs2 signaling predominates in certain tiss...
متن کاملSynaptic depression creates a switch that controls the frequency of an oscillatory circuit.
Synaptic depression is a form of short-term plasticity exhibited by many synapses. Nonetheless, the functional significance of synaptic depression in oscillatory networks is not well understood. We show that, in a recurrent inhibitory network that includes an intrinsic oscillator, synaptic depression can give rise to two distinct modes of network operation. When the maximal conductance of the d...
متن کاملA reciprocal regulatory circuit between CD44 and FGFR2 via c-myc controls gastric cancer cell growth
Despite their suggested importance, the mechanistic roles of FGFR2 and gastric cancer stem cell (GCSC) marker CD44 remain unclear. We investigated cross talk between CD44 and FGFR2. FGFR2 and CD44 positively regulate each other's expression. While FGFR2 suppresses c-Myc transcription, CD44 activates it. c-Myc in turn augments FGFR2 transcription. CD44 knockdown (KD) depleted FGFR2 and other GCS...
متن کاملA Dynamic Reciprocal RBR-PRC2 Regulatory Circuit Controls Arabidopsis Gametophyte Development
Unlike animals that produce gametes upon differentiation of meiotic products, plants develop haploid male and female gametophytes that differentiate gametes such as sperm, egg and central cells, and accessory cells [1, 2]. Both gametophytes participate in double fertilization and give rise to the next sporophytic generation. Little is known about the function of cell-cycle genes in differentiat...
