Pembrolizumab, exemestane, and leuprolide in premenopausal estrogen receptor-positive/HER2-negative advanced breast cancer

ABSTRACT: We evaluated the efficacy of combining pembrolizumab (anti-PD1 antibody), exemestane (nonsteroidal aromatase inhibitor), and leuprolide (gonadotropin-releasing hormone agonist) for 15 patients with ER+/HER2− premenopausal MBC who had failed one to two lines of hormone therapy without chemotherapy.

mRNA-seq of zebrafish treated with sex hormone 17β-estradiol and aromatase inhibitor exemestane during sex development

Project description:To identify key genes in the early sex development of zebrafish, we generated zebrafish (AB strain) feminized by sex hormone 17β-estradiol (E2, CAS: 50-28-2, 100 ng/L) and masculinized by aromatase inhibitor exemestane (EM, CAS: 107868-30-4, 10 μg/L), and detected their transcriptomes by RNA-seq.

Transcription profiling of human cell lines resistant to aromatase inhibitor, tamoxifen-resistant and LTEDaro lines

Project description:MCF-7aro cells were used to generate a cell culture model system that is resistant to 3 aromatase inhibitors (AIs), letrozole, anastrozole and exemestane. For comparison, the MCF-7aro cells were also used to generate the tamoxifen-resistant cells as well as long-term estrogen deprived, LTEDaro. Affymetrix microarray analysis was performed to determine changes in gene expression that are unique to AI-resistance. Experiment Overall Design: For control purposes, MCF-7aro cells were cultured without any hormone or inhibitor as well as a hormone-only control (T-only). Resistant cells were grown in the presence of testosterone, T+LET R (letrozole), T+ANA R (anastrozole), T+EXE R (exemestane), T+TAM R (Tamoxifen). In addition, testosterone-free resistant lines were generated, LTEDaro, ANA R and EXE R. 6 replicates were generated for the hormone-containing resistant lines and 3 replicates for the hormone-free resistant lines.

Molecular changes in premenopausal estrogen receptor-positive primary breast cancer after oophorectomy

Project description:For premenopausal women with primary ER+ breast cancer, oophorectomy (OvX) is an evidence-based cost-effective option and is standard treatment in many countries. However, there is virtually no data describing the effects of OvX on breast tumour biology. We therefore characterized the endocrine and genome-wide transcriptional impact of OvX in 56 premenopausal women with ER+ breast cancer for two weeks prior to mastectomy. Plasma estradiol concentrations decreased from 421±305 to 24.1±24.5 pmol/l (mean±sd) 24 hours after OvX and to 8.8±7.3pmol/l two weeks later at mastectomy. Ki67 decreased in 33/36 (91.7%) tumours. The expression of 655 genes changed significantly (FDR<1%) with an absolute mean fold-change (FC) ≥1.25 (257 up, 398 down). Archetypal oestrogen-regulated genes, proliferation-associated genes and putative progesterone-regulated genes were strongly down-regulated. The gene expression changes did not differ according to HER2 status and correlated strongly with those after aromatase inhibitor (AI) treatment in 81 postmenopausal women. However, after OvX the mean FC was significantly higher compared to AI. In conclusion, changes in tumoural gene expression after OvX were largely similar but of a greater magnitude to those observed after AI in postmenopausal patients but OvX appeared to have a greater effect on progesterone-regulated genes than AI.

mRNA-seq of gonads from adult zebrafish treated with aromatase inhibitor and control

Project description:To explore the transcriptional effects of aromatase inhibitors on sex differentiation of zebrafish, we exposed 3-month-old zebrafish (AB strain) to the third generation aromatase inhibitor Exemestane (CAS: 107868-30-4) and characterized transcript abundance among testes and ovaries after 32 days of drug exposure. After the drug treatment, we dissected zebrafish gonads, isolated polyA+ RNA and performed high-throughput RNA-Seq analysis.

Antitumor Activity of Z-endoxifen in Aromatase Inhibitor-Sensitive and Resistant Estrogen Receptor-Positive Breast Cancer

Project description:The overarching goal of this study was to explore the antitumor activity of Z-endoxifen, a tamoxifen metabolite, with first-line endocrine therapies tamoxifen and letrozole in the letrozole-sensitive MCF7 aromatase expressing model (MCF7AC1), and with second-line endocrine therapies including tamoxifen, fulvestrant, exemestane, and exemestane plus everolimus, in letrozole-resistant MCF7 model (MCF7LR) in vivo. We used microarray to identify genes that are commonly and differently reguated by Z-endoxifen and tamoxifen treatments in the letrozole-resistant MCF7LR tumors.
