Previous studies have shown that both bipolar disorder (BPD) and psychomotor agitation (PMA) are associated with substance dependence. These two findings have yet to be integrated, despite evidence that PMA is closely linked with the bipolar spectrum. Accordingly, the current study examined whether BPD and PMA had unique or overlapping associations with substance dependence disorders. Participa...

AIM In contrast with findings in amyotrophic lateral sclerosis (ALS), cognitive impairments have as yet not been shown in the lower motor neuron variant of motor neuron disease, progressive spinal muscular atrophy (PMA). The objective of this study was to investigate cognitive function in PMA and to compare the cognitive profile with that of ALS. In addition, visuospatial functions were assesse...

The effects of insulin and phorbol 12-myristate 13-acetate (PMA) on the levels of cellular phosphoinositides were investigated in 3T3-L1 adipocytes. Stimulation for 4 min with PMA (1 microM) or insulin (10 nM) increased levels of PtdIns(3,4,5)P3 approx. 2-fold and 6-fold respectively. PMA also had a small effect on the cellular levels of PtdIns4P, whereas insulin had no effect on PtdIns4P level...

Exposure of cells to phorbol 12-myristate 13-acetate (PMA) has been reported to result in resistance to the acute biological effects of insulin and an associated reduction in insulin-receptor tyrosine kinase activity. To investigate the relationship of insulin receptor autophosphorylation with a longer-term action of insulin the effect of PMA on insulin-stimulated receptor down-regulation was e...

Perpendicular magnetic anisotropy (PMA) is a key property of magnetoresistive random access memory (MRAM). To increase areal density MRAM it important to find way enhance the PMA. Recently strong enhancement PMA by inserting an ultrathin LiF layer at Fe/MgO interface was reported [T. Nozaki et al., NPG Asia Materials (2022) 14: 5]. understand origin observed we perform first-principles calculat...

The treatment of human tonsillar T-lymphocytes with 4-phorbol 12-myristate 13-acetate (PMA), resulted in about two fold increase in glucocorticoid receptor (GR) number, without any significant change in the receptor affinity. This increase disappeared in the presence of cycloheximide. Alone, PMA and calcium ionophore A23187 did not affect, but together stimulated, like phytohaemagglutinin (PHA)...

The K562 cell line undergoes megakaryocytic differentiation in response to phorbol 12-myristate 13-acetate (PMA) stimulation. This event correlates with mitogen-activated protein kinase activation, cell cycle arrest, and expression of the Egr-1 transcription factor. We have isolated K562 cells that are resistant to the growth-inhibitory action of PMA. Molecular characterization demonstrates tha...

The tumor promoter phorbol 12-myristate 13-acetate (PMA) rapidly decreased the rate of 86Rb+ uptake into BALB/c 3T3 preadipose cells. The component of total 86Rb+ influx affected by PMA is insensitive to ouabain but sensitive to the diuretic furosemide. Experiments designed to investigate the characteristics of the K+ transport system sensitive to PMA revealed that: (i) 86Rb+ uptake is highly d...

Phorbol myristate acetate (PMA) and ionomycin (Io) can induce T cell activation and proliferation. Furthermore, they stimulate activation-induced cell death (AICD) in mature lymphocytes via Fas/Fas ligand (FasL) up-regulation. In this study, we explored the influence of PMA/Io treatment on glioblastoma cells, and found that AICD-like phenomena may also occur in glioma. Using the MTT assay and c...

Incubation of murine bone marrow-derived macrophages (BMM) in medium containing recombinant macrophage colony-stimulating factor (rM-CSF) stimulated influx, efflux, and the net accumulation of the fluid-phase pinocytic marker, lucifer yellow (LY). Stimulation was dose dependent, occurred within 5 min of addition of the growth factor, and was sustained. Previous experiments had shown that BMM tr...
