Signaling rewiring allows tumors to survive therapy. Here we show that the decrease of the master regulator microphthalmia transcription factor (MITF) in lethal prostate cancer unleashes eukaryotic initiation factor 3B (eIF3B)-dependent translation reprogramming of key mRNAs conferring resistance to androgen deprivation therapy (ADT) and promoting immune evasion. Mechanistically, MITF represses through direct promoter binding eIF3B, which in turn regulates the translation of specific mRNAs. Genome-wide eIF3B enhanced cross-linking immunoprecipitation sequencing (eCLIP-seq) showed specialized binding to a UC-rich motif present in subsets of 5' untranslated regions. Indeed, translation of the androgen receptor and major histocompatibility complex I (MHC-I) through this motif …

Gaps In Public Awareness About Brca And Genetic Testing In Prostate Cancer: Social Media Landscape Analysis., Stacy Loeb, Philip Massey, Amy E. Leader, Sameer Thakker, Emily Falge, Sabina Taneja, Nataliya Byrne, Meredith Rose, Matthew Joy, Dawn Walter, Matthew S. Katz, Risa L. Wong, Preethi Selvan, Scott W. Keith, Veda N. Giri

BACKGROUND: Genetic testing, particularly for BRCA1/2, is increasingly important in prostate cancer (PCa) care, with impact on PCa management and hereditary cancer risk. However, the extent of public awareness and online discourse on social media is unknown, and presents opportunities to identify gaps and enhance population awareness and uptake of advances in PCa precision medicine.

OBJECTIVE: The objective of this study was to characterize activity and engagement across multiple social media platforms (Twitter, Facebook, and YouTube) regarding BRCA and genetic testing for PCa compared with breast cancer, which has a long history of public awareness, advocacy, and prominent social media …

Performance Of Prostate Cancer Recurrence Nomograms By Obesity Status: A Retrospective Analysis Of A Radical Prostatectomy Cohort., Charnita Zeigler-Johnson, Aaron Hudson, Karen Glanz, Elaine Spangler, Knashawn H Morales

Department of Medical Oncology Faculty Papers

BACKGROUND: Obesity has been associated with aggressive prostate cancer and poor outcomes. It is important to understand how prognostic tools for that guide prostate cancer treatment may be impacted by obesity. The goal of this study was to evaluate the predicting abilities of two prostate cancer (PCa) nomograms by obesity status.

METHODS: We examined 1576 radical prostatectomy patients categorized into standard body mass index (BMI) groups. Patients were categorized into low, medium, and high risk groups for the Kattan and CaPSURE/CPDR scores, which are based on PSA value, Gleason score, tumor stage, and other patient data. Time to PCa recurrence …

Examining Relationships Between Age At Diagnosis And Health-Related Quality Of Life Outcomes In Prostate Cancer Survivors., Christine J. Kurian, Amy Leader, Melissa S.Y. Thong, Scott W. Keith, Charnita Zeigler-Johnson

Department of Medical Oncology Faculty Papers

BACKGROUND: Patient reports of health related quality of life can provide important information about the long-term impact of prostate cancer. Because patient symptoms and function can differ by age of the survivor, the aim of our study was to examine patient-reported quality of life and prostate symptoms by age at diagnosis among a registry of Dutch prostate cancer survivors.

METHODS: A population of 617 individuals from the Patient Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) database was surveyed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) and prostate symptom …
