Experimental details: Western blot analysis of CHIP was performed by loading 40 µg of MCF-7 cell lysates and 3 µL PageRuler Prestained Protein Ladder (Product # 26619) per well onto a 10% Tris-HCl polyacrylamide gel. Proteins were transferred to a NC membrane and blocked with 5% skim milk/PBS-T for 1 h at room temperature. CHIP was detected at 35 kDa using a CHIP antibody (Product # PA1-015) at 1:1000 dilution in 5% BSA/PBS-T buffer overnight at 4°C on a rocking platform, followed by a goat anti-rabbit IgG-HRP secondary antibody at a dilution in 5% skim milk/PBS-T of 1:3000 for 2 hour at room temperature. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080). Data courtesy of Dr. Wei Xu at the University of Wisconsin, Madison, WI.

Experimental details: Western blot analysis of Carboxyl Terminus of Hsc70-Interacting Protein (CHIP) was performed by loading 20 µg of total protein extracted from the left hemisphere (Left lane)or right hemisphere (right lane) of a normal C57BL/6 mouse brain per well on an SDS-PAGE gel. Proteins were transferred to a membrane, blocked with 5% non-fat dry milk, and probed with a CHIP polyclonal antibody (Product # PA1-015) at a dilution of 1:1000, followed by a HRP-conjugated goat anti-rabbit IgG secondary antibody. Detection was performed using a chemiluminescent substrate. Data courtesy of the Innovators Program.

Experimental details: Figure 5 Searching for the E3-ligase that mediates degradation of BRCA2 upon hyperthermia. ( A ) Effect of hyperthermia on BRCA2 levels upon knock-down of the Heat-shock Protein (HSP)-associated E3-ligase, C terminus of H SC70- I nteracting P rotein (CHIP), in U2OS cells using two different siRNAs. Arrow on the right next to the CHIP panel indicates the predicted position of the CHIP protein. ( B ) Effect of hyperthermia on BRCA2 levels upon knock-down of the SUMO-E3 ligases Protein Inhibitor Of Activated STAT( PIAS) 1-4 in U2OS cells using siRNAs. ( C ) Effect of hyperthermia on BRCA2 levels upon siRNA knock-down of DNA-repair-related, SUMO-targeted ubiquitin ligases, Ring Finger (RNF) 4 and RNF111. ( D ) Detection of BRCA2 and BRCA1 in UWB1.289 (BRCA1-) cells with or without complementation of wild type BRCA1 (wtBRCA1). ( E ) Detection of BRCA2 in U2OS cells treated with increased doses of the neddylation-inhibitor MLN4924, added 30 min prior to hyperthermia. ( F ) Detection of BRCA2 in U2OS cells treated with or without hyperthermia in the presence of proteasome inhibitor MG132 (10 uM) or the E1-activating enzyme inhibitor PYR-41 (10 uM). Inhibitors were added 1 h prior to hyperthermia treatment, and left on for the duration of the treatment.
