Introduction: Retrotransposons (REs) constitute nearly half of the genome and include long terminal repeat (LTR) elements, Long INterspersed Elements (LINE), and Short INterspersed Elements (SINE). REs are typically silenced in somatic tissues via DNA methylation but can be reactivated through DNA hypomethylation, potentially impacting gene regulation. Here, we investigate genome-scale profiles of RE methylation in high-grade serous ovarian carcinoma (HGSOC) and associations with survival among Black women.

Methods: Methylation levels of LTR, LINE-1, and Alu (type of SINE) in 200 HGSOC tumors were predicted using a random forest approach and clustered using multiple consensus algorithms. Associations between RE methylation clusters …

Belumosudil (KD025), an oral, selective, Rho-associated, coiled-coil-containing protein kinase 2 (ROCK2) inhibitor, is approved for third-line treatment of chronic graft-versus-host disease (cGVHD). Previous studies demonstrated that ROCK2 inhibition reduces blood interleukin-17 (IL-17) activity and promotes regulatory T-cell (Treg cell) recovery. However, these studies did not evaluate immune responses within cGVHD-affected tissues. This study assessed tissue-level immune dynamics in 20 patients with oral cGVHD from the phase 2 ROCKstar trial, before and after 6 months of belumosudil treatment, focusing on key effector sites (oral mucosa [OM], minor salivary glands [MSGs], and skin) and the peripheral blood.

Faculty, Staff and Student Publications

Background: Indoleamine 2,3-dioxygenase 1 (IDO1) is a heme-containing enzyme that degrades tryptophan (Trp) to kynurenine (Kyn), which suppresses effector T cells and reduces antitumor activity. KHK2455 is a long-acting selective IDO1 inhibitor that blocks the heme component of the IDO holoenzyme. Mogamulizumab is a humanized immunoglobulin G1 monoclonal antibody targeting CCR4. KHK2455 + mogamulizumab demonstrated enhanced antitumor activity in preclinical studies, which led to a first-in-human, two-part, multicenter, open-label, phase 1, dose-escalation, cohort-expansion trial (ClinicalTrials.gov identifier NCT02867007) evaluating the safety/tolerability, pharmacokinetics, and IDO1 activity of KHK2455 alone and in combination with mogamulizumab in patients with treatment-refractory advanced solid tumors. …

Understanding disease progression and sophisticated tumor ecosystems is imperative for investigating tumorigenesis mechanisms and developing novel prevention strategies. Here, we dissected heterogeneous microenvironments during malignant transitions by leveraging data from 1396 samples spanning 13 major tissues. Within transitional stem-like subpopulations highly enriched in precancers and cancers, we identified 30 recurring cellular states strongly linked to malignancy, including hypoxia and epithelial senescence, revealing a high degree of plasticity in epithelial stem cells. By characterizing dynamics in stem-cell crosstalk with the microenvironment along the pseudotime axis, we found differential roles of ANXA1 at different stages of tumor development. In precancerous stages, reduced …

Objective: Many epithelial ovarian cancer (EOC) risk factors relate to sex hormones. The association between these factors and the expression of androgen receptor (AR), estrogen receptor-α (ER), and progesterone receptor (PR) in tumors is unknown.

Method: We linked epidemiologic, AR/ER/PR tumor expression, and survival data from 19 studies in the Ovarian Cancer Association Consortium (OCAC; 4762 cases, 20,888 controls) and the Ovarian Tumor Tissue Analysis (OTTA) consortium (5737 cases). We estimated odds ratios (ORs) and 95 % confidence intervals (CIs) between hormonally-linked factors and tumor AR/ER/PR expression using polytomous logistic regression. We assessed survival by AR/ER/PR tumor expression overall and …
