  2023-12-11

  

  In our studies of leucine and BCH in pancreatic islets and clonal insulin cell lines, we noticed that leucine was a slightly stronger stimulant of insulin release. Previous studies showed that leucine can be metabolized to CO2[11], [12], [13], [14] and can increase acetoacetate in pancreatic islets

  Enhanced arginase activity and the resultant decreases in L-arginine levels can also impair T cell mediated immune function and allow tumor growth by limiting the supply of L-arginine needed for the formation of cytotoxic levels of NO by iNOS [10]. Increased arginase expression/activity may also lim

  The specific mechanism and neurotoxic Aβ MM-102 receptor are yet to be elucidated, however recent studies have provided significant evidence for the amyloid channel hypothesis. These reports have established that relatively small oligomers ( Conflict of interest Acknowledgements This work was f

  Volatile esters are important to wine quality and to fresh berry grape flavor, especially in fox grapes (V. labrusca) [16]. Volatile esters such as Z-3-hexyl acetate can be found in V. vinifera ‘Cabernet Sauvignon’ berries albeit at low levels and their accumulation diminishes to below detection lev

  Introduction Clinical manifestations of Alzheimer's disease (AD) are mainly characterized by progressive intellectual deterioration, memory impairment, cognitive impairment, and psychiatric symptoms. The pathogenesis of AD remains unclear, mainly containing genetic factors, neurotransmitter disor

  2023-12-08

  

  Regarding A1Rs and A2ARs, basal conditions generate a low tone of endogenous adenosine and cause A1R activation, in contrast to situations of increased adenosine where A2AR activation becomes dominant. When adenosine concentrations rise, e.g. during hypoxia, also time appears likely important in reg

  2023-12-08

  

  Metformin's pluripotent roles are alluded to in terms of its antitumorigenic, glucose-lowering, and cardioprotective effects, which are due in part to its upregulation of AMPK activity [39,40]. Metformin's glucose-lowering effect is a result of reduced hepatic gluconeogenesis, whereas improved insul

  Purification of Rv2477c. In order to investigate the catalytic capabilities of Rv2477c, we expressed the protein as an N-terminal histidine-tagged fusion protein in E. coli BL21 cells and purified the protein by cobalt-affinity chromatography. As shown in Fig. 2A, the 65 kDa fusion protein was expre

  The apoptosis-promoting Bcl-2 family includes BH3-only proteins (e.g., Bim, Bid and Bad) and multiple-domain proteins (e.g., Bax and Bak). At the time of apoptosis stimulation (e.g., DNA damage), only the BH3-only protein is activated, directly or indirectly promoting Bax/Bak oligomerization, changi

  To date, attention has been directed towards new molecular targets in luminal phenotype (ER-positive), such as CDK4/6 and, to a lesser extent, androgen receptor (AR) pathways [8]. While the role of CDK4/6 has been elucidated and their inhibitors have shown a benefit in luminal BC, the role of AR in

  It has been known for a while that oxygenation (the addition of oxygen) of Aβ can inhibit the formation of amyloids and diminish their cytotoxicity. Photo-oxygenation of Aβ started with fullerenes almost a decade ago by Toshima and co-workers. Later, porphyrins and polyoxometalates were used as well
