  The gene SRD5A2 encodes the 5-α-reductase enzyme, which converts testosterone into dihydrotestosterone. Although dihydrotestosterone levels are considerably lower than testosterone, dihydrotestosterone has a five-fold stronger binding capacity to the androgen receptor and, thereby, a considerably mo

  Given the recent discovery of regions of single-stranded DNA in the nuclei of hypoxic cells, the role for ATR in the response to hypoxic stress seems clearer . Zou and Elledge demonstrated that both Ddc 2 (the homolog of ATRIP) and ATRIP have a lower affinity for double-strand breaks than they do f

  Current limitations and future directions There are several limitations associated with PET imaging of aromatase using carbon-11 labeled aromatase inhibitors. Due to the very short half-life of carbon 11 (20min), PET studies with currently available, validated tracers can only be performed in med

  Physiology of the apelin pathway Role of apelin in heart disease Both apelin and apelin receptor null mice manifested moderate reduction in cardiac contractile function under basal conditions and their exercise capacity was markedly reduced (Table 1) [56]. Apelin has direct effects on the prop

  Over expression of the inflammatory cytokines, MMPs and COX-2 act as an important inducer of chronic inflammation. COX-2 catalyzes the biosynthesis of prostaglandins (PGs), and induced expression was observed in cyclin dependent kinase inhibitor stimulated with pro-inflammatory cytokines or bacteria

  2024-01-30

  

  Testosterone can be converted into estrogens by aromatase action. Aromatase is encoded by CYP19, belongs to cytochrome P450 superfamily, and synthesizes estradiol (E2) and estrone (E1) from testosterone and androstenedione respectively (Fig. 1). Aromatase is expressed in the ORS of anagen hair folli

  We also found that the size of mEPSC amplitude was reduced in unc-43 mutants, consistent with the decrease in synaptic GLR-1/GLR-2 heteromeric receptors. The decrease in mEPSC amplitude was not as great as that observed when measuring current in response to pressure application of glutamate. These d

  These findings suggest that eventually more than one 12/15-lipoxygenase isoform may play a role in human atherosclerosis. Humans have two 12-lipoxygenases and two 15-lipoxygenases which show different expression patterns, substrate specificities and stereo-selective metabolism [1]. However, in Pexme

  2024-01-29

  

  According to their structures and substrate specificity, MMPs are divided into five major groups: collagenases (e.g., MMP1), gelatinases (e.g., MMP2, MMP9), stromelysins (e.g., MMP3, MMP10), matrilysins (e.g., MMP7), and membrane-type MMPs [7]. Among them, MMP1 is a major collagenase that degrades t

  Introduction Dementia is a common disease in the elderly, and a significant source of disability, healthcare spending, and long-term care admissions. There is evidence to suggest that testosterone plays a role in cognitive functioning, and lower serum levels correlate with higher amyloid deposits (

Indeed, we have previously shown that FIN completely revers

  Many reports have well documented that signaling pathways play a pivotal role in controlling longevity. The most studied of these pathways is the IGF-1 pathway [11,12]. A disruption of this pathway has been found to extend longevity in different groups of species starting from Caenorhabditis elegans
