Our findings further corroborate other studies showing that an activation of MAPK signaling pathway in U-87MG glioma cells leads to a proliferation arrest mediated by an increase in EGR-1 expression which concomitantly stimulates p21 transcription [26].
Synovial fibroblast IL-6 production has been shown to inhibit bone formation and to concomitantly stimulate bone resorption and pannus formation [ 40].
Indeed, UCN-01 has been shown to downregulate Akt activation (but concomitantly stimulate ERK1/2) in head and neck squamous cell carcinoma (Amornphimoltham et al, 2004; Kondapaka et al, 2004).
Mutations of Ura7 and Ura8 that lead to a reduction of CTP product inhibition decrease cyclopentenyl cytosine sensitivity of the enzymes; these mutations concomitantly stimulate neutral lipid synthesis, and lead to a de-repression of inositol biosynthesis and a shift of PC synthesis from the CDP-DAG pathway to the Kennedy pathway [132].
As part of this response, EIF pathways are targeted to facilitate restoration of protein homeostasis through prevention of misfolded protein accumulation that occurs under conditions of physiological and/or environmental duress, while concomitantly stimulating cells that contain conformationally defective proteins to initiate apoptosis [ 29– 329.
Synergistic effects have been observed between endosomal TLRs, like augmentation of NF-κb and IFN regulatory factor (IRF) activation, when monocyte-derived macrophages and DCs are stimulated concomitantly with TLR8, as well as with TLR3 and TLR4 ligands.
In normal and diabetic rats (the Zucker Diabetic Fatty [ZDF] model), a single oral dose of dapagliflozin stimulated glucose excretion concomitantly with an increase in urine volume.
Normal T cells when stimulated generate effectors that downregulate CD3ζ and concomitantly upregulate FcRγ in the TCR complex, thus functionally replacing the CD3ζ chain [ 43].
Since we previously reported finding that Rab35 and MICAL-L1 concomitantly accumulate at Arf6-positive recycling endosomes when PC12 cells are stimulated with NGF (Kobayashi and Fukuda, 2013a), we investigated the subcellular localization of Rab8, Rab13, and Rab36 in NGF-stimulated PC12 cells and in control PC12 cells.
Another intriguing finding of the present study is the observation that insulin stimulated IRS-1 serine phosphorylation in the absence of T, while concomitantly inhibiting the phosphorylation AKT beyond 30 minutes of insulin exposure (Figures 2A and 3A).
