Supplemental Figure S2 from A Bis-Indole–Derived NR4A1 Antagonist Induces PD-L1 Degradation and Enhances Antitumor Immunity

<p>Supplemental Figure S2. Quantitation of results in Figure 1F and 1G. and mRNA results A. Breast cancer cells were treated with Cl-OCH3 (Fig. 1F) and effects on PD-L1, NR4A1 and Sp1 were determined by western blots and quantitation of the results are summarized. B. MDA-MB-231 and 4T1 cells were treated with NR4A1 antagonists, MG132 and their combinations, whole cell lysates were analyzed by western blots (Fig. 1G) and quantitation of the results are summarized. Results of both studies (A, B) are means {plus minus} SD for at least 3 replicate determinations for each treatment groups and changes in expression were determined relative to the control group (set ratio) significantly (p<0.05) decreased effects are indicated (*) and inhibition (reversal of degradation) by MG132 is also indicated (**). C. Basal PD-L1 and NR4A1 mRNA levels in cancer cell lines were determined as described in the Methods.</p>
