(from ATCC, VA) and genetically modified—GFP-PEST HT1080 (generated
previously in our laboratory35 (link)), HEK293T
(from ATCC, VA), and SW480 (gift from Corinne Quittau-Prévostel,
from ATCC, VA) cells were grown in DMEM GlutaMAX (Gibco, IL) supplemented
with 10% FBS at 37 °C at 5% CO2. HT1080 cell medium
was further complemented with MEM NEAA (Gibco, IL). EGI-1 cells (gift
from Laura Fouassier and Nicolas Kuszla, from ATCC, VA) were grown
in DMEM 1× + GlutaMAX-1, 1 g/L
sucrose”) + pyruvate (21885-025, Gibco, IL) supplemented with
10% FBS, 100 UI/L of penicillin, 100 μg/mL of streptomycin,
and 10 mmol/L of HEPES. HeLa stably expressing NanoLuciferase-Hsp70
was generated in our laboratory,6 (link) as well
as DPH2KD HeLa cells35 (link) according to Picco
et al.36 (link) HeLa stably expressing CD8-GFP
was selected with hygromycin B (50 mg/mL, Invitrogen, MA) after lipofectamine
2000 transfection. Cells were transfected at a 70% confluency with
lipofectamine 2000 (Invitrogen, MA) according to the manufacturer’s
instructions.
