Human Cytomegalovirus infection inhibits β-catenin nuclear translocation in EVTs

HCMV infection leads to β-catenin protein accumulation in a discrete juxtanuclear region.

  • Extravillous trophoblast (EVT) cell line (SGHPL-4) derived from first trimester placenta.
  • Cells were seeded on glass coverslips and infected with Towne-GFP (MOI of 1–2) or mock-infected for 48 hr.
  • Cells were then treated with 150 ng/ml Wnt-3A or 20 mM LiCl for 6 hr followed by immunostaining for β-catenin using a mouse anti-β catenin antibody, followed by a goat anti-mouse secondary IgG conjugated to AlexaFluor 555.
  • Nuclei were counterstained with DAPI. Mouse IgG was used as an isotype control. GFP positive cells represent infected cells. Arrowheads point to nuclear accumulation of β-catenin. Arrows indicate aggregation of β-catenin in infected cells.
