  Summary and future Introduction Androgen activity is critical for a wide range of developmental and physiological responses and is especially important in male sexual differentiation and maturation. The biological activity of androgens occurs through binding to the androgen receptor (AR) and t

  Introduction AMP-activated protein kinase (AMPK) is mainly known as a highly conserved and ubiquitously expressed energy sensor that is highly sensitive to changes in cellular energy levels (by sensing increases in AMP:ATP and ADP:ATP ratios) and makes appropriate adjustment to balance the consumpt

  Recently, two distinct small-molecule inhibitors of PHGDH were identified using high-throughput screens, both of which inhibit de novo serine biosynthesis and show selective toxicity to cancer aromatase inhibitor with high SSP flux [50,51]. The inhibitor NCT-503, which has an IC50 of 2.5μM, reduces

  In a recent series of studies from our laboratory, to characterize the contractile systems within the rat gamma-Glu-Cys wall, three conditions were identified that led to detrusor activity: spontaneous micro-contractions, electrical field stimulated (EFS) contractions and muscarinic agonist induced

  A highly attenuated B. pertussis strain, named BPZE1, has recently been described [10]. It produces enzymatically inactive pertussis toxin (PT), no dermonecrotic toxin and only trace amounts of tracheal cytotoxin. Markedly reduced lung pathology was observed in mice intranasally (i.n.) infected with

  In patients with spina bifida and spinal cord injury, fecal incontinence is a serious issue that can impair activities of daily living and patient self-esteem. To address this Malone et al. first described the Antegrade Continence Enema (ACE) procedure in 1990 [1], which achieves continence by all

High s6 kinase levels of p62 were associated with long progression-free survival of patients w

  The overall mechanism of the Cdc48 complex resembles that of the 19S regulatory subunit of the proteasome, which also uses receptor proteins to bind polyubiquitin chains attached to a substrate and employs a translocation mechanism (for review, see Kish-Trier and Hill, 2013). As with Cdc48, full sub

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
