Disease relevance of Sqle

  • Moreover, Leish-111f formulated with MPL-SE conferred immunity to leishmaniasis for at least 3 months [1].
  • We have evaluated activated alpha2-macroglobulin (alpha2M*) and a squalene-based stable emulsion containing monophosphoryl lipid A (MPL-SE) with granulocyte-macrophage colony stimulating factor (GM-CSF) as adjuvants to enhance the immunogencity of candidate HIV immunogens [2].
 

Psychiatry related information on Sqle

  • Last we report the finding from in vitro and in vivo experiments that MAPkase (Erg 1 and 2) is the molecular chain of events driven both by light and neurotrophins, likely at the bases of the phenomena of plasticity observed during the critical period [3].
 

High impact information on Sqle

  • Using the DPK CD4+8+ thymocyte precursor cell line, we demonstrate that the early growth response-1 gene (Erg-1), encoding a zinc finger transcription factor, is rapidly upregulated after TCR stimulation [4].
  • In addition to coordinating these enzymes, CAR plays other roles in hepatic gene expression: CAR represses various genes including carnitine palmitoyltransferase 1a and phosphoenolpyruvate carboxykinase 1 in response to PB, and the receptor regulates the constitutive expression of genes such as squalene epoxidase [5].
  • These results suggest that inhibition of the biosynthesis of ergosterol is an important target for the action of the 2-propen-1-amine derivative on T. cruzi through the inhibition of the enzyme squalene epoxidase [6].
  • The LD50 (+/- SE), determined using intraperitoneal (ip) injection, for the mouse and hamster were low at 5.0 +/- .3 and 13.7 +/- .9 mg/kg, respectively [7].
  • Microarray gene expression analysis of the Fob3b obesity QTL identifies positional candidate gene Sqle and perturbed cholesterol and glycolysis pathways [8].
 

Biological context of Sqle

 

Associations of Sqle with chemical compounds

  • The sodium-dependent component of taurine uptake was significantly lower in C57BL/6J vesicles relative to control (C3H/HeJ strain): 2.9 +/- 0.7 vs. 9.4 +/- 0.3 (SE) pmol.mg protein-1.15 s-1, respectively; P less than 0.001 [10].
 

Analytical, diagnostic and therapeutic context of Sqle

  • No adverse reactions were observed when three subcutaneous injections of the Leish-111f polyprotein formulated with either MPL-squalene (SE) or Ribi 529-SE were given to BALB/c mice [1].
