Understanding species-specific and conserved RNA-protein interactions in vivo and in vitro.

While evolution is often considered from a DNA- and protein-centric view, RNA-based regulation can also impact gene expression and protein sequences. Here we examine interspecies differences in RNA-protein interactions using the conserved neuronal RNA-binding protein, Unkempt (UNK) as model. We find that roughly half of mRNAs bound in human are also bound in mouse.

SAFB associates with nascent RNAs and can promote gene expression in mouse embryonic stem cells.

Scaffold attachment factor B (SAFB) is a conserved RNA-binding protein that is essential for early mammalian development. However, the functions of SAFB in mouse embryonic stem cells (ESCs) have not been characterized. Using RNA immunoprecipitation followed by RNA-seq (RIP-seq), we examined the RNAs associated with SAFB in wild-type and SAFB/SAFB2 double-knockout ESCs.

Association of Oncologist-Patient Communication With Functional Status and Physical Performance in Older Adults: A Secondary Analysis of a Cluster Randomized Clinical Trial.

Importance: The functional status and physical performance of older adults with cancer are underassessed and undertreated despite the high prevalence of impaired functional status and physical performance in this population and their associations with chemotherapy-induced toxic effects and mortality.

Objective: To examine the association between providing oncologists with a geriatric assessment (GA) summary with recommendations and having oncologist-patient conversations about functional and physical performance.

Design, Setting, And Participants: Data for this secondary analysis were collected from October 29, 2014, to April 28, 2017, for a national cluster randomized clinical trial conducted by the University of Rochester Cancer Center National Cancer Institute Community Oncology Research Program evaluating the effect of a GA intervention on patient satisfaction with communication about aging-related concerns.

Evaluating the association of frailty with communication about aging-related concerns between older patients with advanced cancer and their oncologists.

Background: A geriatric assessment (GA) intervention improves communication about aging-related concerns, but its effect on communication in patients with various levels of frailty is unknown.

Methods: This was a secondary analysis of a nationwide trial of patients aged ≥70 years with incurable cancer and impairment on 1 or more GA domains (ClinicalTrials.gov Identifier NCT02107443; principal investigator Supriya G.
