M V Autieri et al.
Cell regulation, 1(13), 1015-1025 (1990-12-01)
We have shown previously that cytoplasmic extracts from actively dividing lymphoid cells are capable of inducing DNA synthesis in isolated nuclei. One of the factors involved in this activity, ADR, appears to be a greater than 90 kDa heat-labile protease....
Li Chen et al.
Food chemistry, 293, 537-544 (2019-06-04)
To verify the effect of protein phosphorylation on glycolysis and elucidate the regulatory mechanism from the perspective of enzyme activity, ovine muscle was treated with a kinase inhibitor, dimethyl sulfoxide, or a phosphatase inhibitor and the activities of glycogen phosphorylase...
Haowei Song et al.
The Journal of biological chemistry, 285(44), 33843-33857 (2010-08-25)
The Group VIA phospholipase A(2) (iPLA(2)β) hydrolyzes glycerophospholipids at the sn-2-position to yield a free fatty acid and a 2-lysophospholipid, and iPLA(2)β has been reported to participate in apoptosis, phospholipid remodeling, insulin secretion, transcriptional regulation, and other processes. Induction of...
J W Kasckow et al.
Synapse (New York, N.Y.), 18(4), 354-358 (1994-12-01)
Interleukin-1 (IL1) is a key messenger implicated in endocrine and immune systems that interact to mediate the stress response. Corticotropin-releasing factor (CRF) secretion and synthesis in the NPLC-KC human hepatoma cell line has been shown to respond to IL1 stimulation....
L Kapural et al.
Biochimica et biophysica acta, 1355(3), 331-342 (1997-03-01)
We examined the effects of platelet activators and inhibitors of platelet function on the voltage-gated delayed rectifier K+ current of human megakaryocytes. We found that both the activators such as thrombin, the thrombin receptor peptide (TRP42-47) and ADP and the...
P Amador et al.
Journal of cellular biochemistry, 101(1), 99-111 (2006-12-21)
Sepsis is a systemic response to infection in which toxins, such as bacterial lipopolysaccharide (LPS), stimulate the production of inflammatory mediators like the cytokine tumor necrosis factor alpha (TNF-alpha). Previous studies from our laboratory have revealed that LPS inhibits the...
F O'Rourke et al.
The Biochemical journal, 257(3), 715-721 (1989-02-01)
In contrast with previous reports, it was found that membrane-protein phosphorylation by the catalytic subunit (CS) of cyclic AMP-dependent protein kinase had no effect on Ca2+ uptake into platelet membrane vesicles or on subsequent Ca2+ release by inositol 1,4,5-trisphosphate (IP3)....
S B Hu et al.
Neuroendocrinology, 56(5), 712-718 (1992-11-01)
Catecholamines have been shown to activate hypothalamic corticotropin-releasing factor-41 (CRF) synthesis and release. In order to study the mechanisms involved, fetal hypothalamic cells were cultured and CRF release was measured by radioimmunoassay. Norepinephrine (NE) induced CRF release in a dose-dependent...
Roberta Ribeiro Costa et al.
Cell calcium, 49(3), 191-199 (2011-03-04)
LH increases the intracellular Ca(2+) concentration ([Ca(2+)](i)) in mice Leydig cells, in a process triggered by calcium influx through T-type Ca(2+) channels. Here we show that LH modulates both T-type Ca(2+) currents and [Ca(2+)](i) transients through the effects of PKA...
H C Cheng et al.
The Journal of biological chemistry, 261(3), 989-992 (1986-01-25)
As an important new reagent for studying the cAMP-dependent protein kinase, a 20-residue peptide has been synthesized that corresponds to the active site of the skeletal muscle inhibitor protein. This synthetic peptide inhibits the protein kinase competitively with a Ki...
J Mu et al.
Pflugers Archiv : European journal of physiology, 439(5), 541-546 (2000-04-14)
The potent cannabinoid receptor agonist WIN 55,212-2 produces positive shifts in steady-state inactivation of the potassium A current (IA) in rat hippocampal neurons via an adenosine 3',5'-cyclic monophosphate (cAMP)-, protein kinase A (PKA)-dependent process. This effect is probably mediated by...
Anna Cavaccini et al.
Neuron, 98(4), 801-816 (2018-05-01)
Monoaminergic modulation of cortical and thalamic inputs to the dorsal striatum (DS) is crucial for reward-based learning and action control. While dopamine has been extensively investigated in this context, the synaptic effects of serotonin (5-HT) have been largely unexplored. Here...
S B Hu et al.
Brain research, 574(1-2), 266-270 (1992-03-06)
5-Hydroxytryptamine (5-HT) has been shown to activate the hypothalamo-pituitary-adrenal axis, possibly by a direct action on hypothalamic CRF synthesis and release. In order to study the mechanisms involved in this effect, foetal hypothalamic cells were cultured and corticotropin-releasing factor-41 (CRF)...
