Project description:This pilot study aimed to accomplish 3 distinct but related goals. First, we described the structural phenotype of uterine/endometrial injury after alkylating chemotherapy sonographically and histologically. Second, we investigated the molecular impact of alkylating chemotherapy exposure on messenger RNA expression and epigenetic changes in endometrial biopsy (EMB) tissue homogenates. Third, we investigated the feasibility of performing ultrasonographic and EMB-based assessments in reproductive-age cancer survivors. Because of limited information available in this area of inquiry, this approach is exploratory and should prove to be hypothesis-generating. The main outcome measures of this study included endometrial thickness (EMT) and uterine volume on transvaginal ultrasound. Endometrial histology, DNA methylation, and RNA-seq on EMB samples, and pain scale assessment before and after EMB.
Project description:Genome wide DNA methylation profiling of samples from adult survivors of childhood and young adult cancer, using the Illumina Infinium Human MethylationEPIC Beadchip arrays. Samples included 32 samples, all sampled at least 10 years after diagnosis . Specific therapies and duration between sampling and diagnosis varied.
