Project description:Gliomas are immunologically cold tumors that can be broken into several categories based on either RNA expression profiles or methylation profiles, with isocitrate dehydrogenase (IDH) mutations defining a major segregration between types. IDH mutant gliomas often exhibit defects in the retinoic acid pathway. We treated mice harboring IDH mutant gliomas with all-trans retinoic acid, and found that this treatment cause reductions in tumor growth and a swith in immune profiles in the tumor microenvironment.
Project description:IDH mutant cells are deficient in retinoic acid production, which impacts downstream gene expression and pathways. We looked at the effect of supplementing IDH mutant glioma cells with ATRA on gene expression and downstream pathways. We compared gene expression changes with IDH WT cells that were also treated with ATRA
Project description:The main purpose of this clinical trial is to learn about the good and the bad effects of all trans retinoic acid (ATRA), atezolizumab and bevacizumab as a possible treatment for advanced colorectal patients.
Participants will be treated with the following combination of these drugs:
1. ATRA will be given in a pill form to be taken twice a day at home for 7 days starting on day 1 of a cycle.
2. Atezolizumab will be given through a vein in arm or through mediport over 60-90 minutes every 2 weeks in the outpatient chemotherapy infusion centers at UTSW.
3. Bevacizumab will be given through a vein in arm or through mediport over 20-40 minutes every 2 weeks in the outpatient chemotherapy infusion centers at UTSW.
