Disease relevance of BLVRB

  • The FR protein was localized to mitochondria and suppressed the growth of colon cancer cells when over-expressed [1].
  • We tested the hypothesis that transduction of FR cDNA in sense or antisense orientation using recombinant adeno-associated virus modulated FR expression and altered proliferation of cervical carcinoma cells (which constitutively overexpress FR genes) [2].
  • A core region of the P1 promoter was sufficient for maximal promoter activity in ovarian carcinoma cell lines but not in OSE cells or in alpha FR-nonexpressing cell lines [3].
  • CONCLUSIONS: Before elective right hepatectomy, the hypertrophy of FLR induced by PVE had no beneficial effect on the postoperative course in patients with normal liver [4].
  • RESULTS: The mean increase of FLR and %FFLR 4 to 8 weeks after PVE were respectively 44 +/- 19% and 16 +/- 7% for patients with normal liver and 35 +/- 28% and 9 +/- 3% for those with chronic liver disease [4].
 

Psychiatry related information on BLVRB

  • Contrary to what is seen in normal individuals, no correlation was found between BMI and serum GHBP levels in anorexia nervosa patients [5].
 

High impact information on BLVRB

  • FR-alpha expression in Jurkat cells facilitated MBG or EBO entry, and FR-blocking reagents inhibited infection by MBG or EBO [6].
  • However, the molecular mechanisms controlling this interaction, especially within the context of FR regulation and folate status, have remained obscure [7].
  • Human cervical carcinoma cells exhibited progressively increasing upregulation of FRs after shifting of folate-replete cells to low-folate media, without a proportionate rise in FR mRNA or rise in hnRNP E1 [7].
  • Abrupt reversal of folate deficiency also led to a rapid parallel reduction in homocysteine and FR biosynthesis to levels observed in folate-replete cells [7].
  • The locus of mutation D112G was found within site 2 of the GH molecule in binding with GH receptor (GHR)/GH binding protein (GHBP) [8].
 

Chemical compound and disease context of BLVRB

  • Therefore, these results suggest that endogenous estrogen status may be an important determinant of the changes in GHBP levels in women with different body weights [9].
  • Neither GH administration to GH-deficient and normal subjects, nor octreotide treatment of patients with acromegaly, significantly altered GHBP activity [10].
  • The soluble fumarate reductase (FR) from Shewanella frigidimarina can catalyse the reduction of 2-methylfumarate with a k(cat) of 9.0 s(-1) and a K(M) of 32 microM [11].
  • BACKGROUND: Selective transarterial chemoembolization (TACE) and portal vein embolization (PVE) could improve the rate of hypertrophy of the future liver remnant (FLR) in patients with chronic liver disease [12].
  • To further elucidate the mechanisms underlying pubertal growth, we treated 14 boys with delayed puberty and short stature with either T (n = 7) or 5alpha-dihydrotestosterone (DHT) (n = 7) and compared the effect on plasma concentrations of GH, IGF-I, and GH binding protein (GHBP) [13].
 

Biological context of BLVRB

 

Anatomical context of BLVRB

  • We have isolated flavin reductase from bovine erythrocytes and show that the activity co-elutes with biliverdin-IX beta reductase [17].
  • The alpha folate receptor (alpha FR) is a membrane glycoprotein that binds folates, and mediates their uptake and that of antifolate drugs. alpha FR is absent on ovarian surface epithelium (OSE) but is detectable during early transforming events in this epithelium, with increasing expression levels in association with tumor progression [3].
  • In isolation, the GHBP is inactive, although it does compete with the receptor for ligand binding in the extracellular space and therefore inhibits the cellular response to GH [18].
  • OBJECTIVE: To assess the impact of liver hypertrophy of the future liver remnant volume (FLR) induced by preoperative portal vein embolization (PVE) on the immediate postoperative complications after a standardized major liver resection [4].
  • Immunohistochemical staining for GHR and GHBP decreased with age; in 12-week-old normal rats, only the early maturing chondrocytes were stained [19].
 

Associations of BLVRB with chemical compounds

 

Physical interactions of BLVRB

  • Truncation of 17 amino acids decreased its affinity toward both hGHBP and GH receptors on intact IM-9 lymphocytes and in liver rat microsomal fraction and inhibited the formation of 1:2 complexes with hGHBP [22].
