Disease relevance of Podxl


Psychiatry related information on Podxl

  • All three anti-A. suum-specific HP studied in detail had hapten-binding profiles remarkably similar to each other, a finding that is in contrast to M511 Id+ HP to S. pneumoniae and PC-protein [6].

High impact information on Podxl


Chemical compound and disease context of Podxl

  • Of the eight anti-P. morganii HP, six exhibited a fine specificity profile for PC and choline analogues only slightly different from M603 Id+ HP induced by S. pneumoniae and PC-protein [6].
  • RESULTS: Among 30 Wilm's tumor (WT)-1- and podocalyxin-positive cell clones, two cell clones stably expressed nephrin as assessed by reverse transcription-polymerase chain reaction (RT-PCR), Northern and Western blotting, and immunofluorescence [8].

Anatomical context of Podxl


Associations of Podxl with chemical compounds

  • The function of podocalyxin is unknown, but it contains most of the protein bound sialic acid in the glomerulus and is considered vital in the structure and function of the glomerular filtration apparatus [9].
  • We conclude that we have cloned and sequenced a novel transmembrane core glycoprotein from rabbit glomerulus, which has many of the characteristics of podocalyxin [12].
  • Consistent with injury-promoting effects of Galpha qQ > L, there was a significant reduction in podocalyxin mRNA as well as nephrin mRNA and protein levels in glomeruli from TG mice compared with non-TG controls [3].
  • PCP is pyrolyzed at high temperatures to form predominantly 1-phenyl-1-cyclohexene (PC) [13].
  • In addition, PC and its major metabolites, as well as piperidine, are considerably less active behaviorally than PCP, which suggests that pyrolysis represents an inactivation process for PCP [13].

Other interactions of Podxl

  • In summary, we find that podocalyxin is a marker of embryonic HSCs and erythroid cells and of adult HSCs and that it may be a valuable marker for the purification of these cells for transplantation [7].
  • RESULTS: As judged by immunostaining for Wilms tumor-1, smooth muscle actin (SMA), podocalyxin, and von Willebrand factor (vWF), we obtained putative endothelial, podocyte and mesangial cell lines [14].
  • The major sialoprotein of the podocyte foot process glycocalyx is a 140-kDa sialoprotein named podocalyxin [12].
  • The phased pattern of newborn mouse ovary differentiation allowed us to (1) extend information on activity and stage specificity of cell type-specific genes; and (2) generate a list of candidate genes involved in primordial follicle formation, including podocalyxin (Podxl), PDGFR-beta, and a follistatin-domain-encoding gene Flst1 [15].

Analytical, diagnostic and therapeutic context of Podxl

  • We studied the expression pattern of the major renal protein Podocalyxin during the development of mouse brain using in situ hybridization [11].
  • Sequence alignments and features analysis confirm GP135 as a canine homolog of podocalyxin, confirming the finding of an earlier independent study [16].
  • This study presents (1) a feasibility, direct binding assay, (2) a comparison of methods to immobilize anti-PC upon the fiber (direct immobilization vs an avidin-biotin bridge), and (3) effectiveness of an elution step to regenerate the fiber [17].
  • An immuno-optical biosensor for the diagnosing of PC deficiencies and monitoring of PC concentrations is being developed for this purpose [17].
