"Ethical Challenges in Novel Gene Therapies for Sickle Cell Disease"
Panelists Melissa Creary and Liza Johnson will describe the current state of therapy for sickle cell disease, and some ethical issues that arise in the emerging use of gene transfer or gene editing for treating the disease. Dr. Johnson will focus on ethical issues identified by patients, and Dr. Creary will discuss some of the social and historical ethical challenges that relate to genetic interventions for sickle cell.

A CSB-PAF1C axis restores processive transcription elongation after DNA damage repair, Diana van den Heuvel, Cornelia G. Spruijt, Román González-Prieto, Angela Kragten, Michelle T.

Abstract: Bulky DNA lesions in transcribed strands block RNA polymerase II (RNAPII) elongation and induce a genome-wide transcriptional arrest. The transcription-coupled repair (TCR) pathway efficiently removes transcription-blocking DNA lesions, but how transcription is restored in the genome following DNA repair remains unresolved. Here, we find that the TCR-specific CSB protein loads the PAF1 complex (PAF1C) onto RNAPII in promoter-proximal regions in response to DNA damage. .... Our findings expose the molecular basis for a non-canonical PAF1C-dependent pathway that restores transcription throughout the human genome after genotoxic stress.

RNA Ensembles from Solvent Accessibility Data: Application to the SAM-I Riboswitch Aptamer Domain, Jingru Xie and Aaron T. Frank, J. Phys. Chem. B 2021, 125, 14, 3486–3493, April 5, 2021 https://doi.org/10.1021/acs.jpcb.0c11503
Abstract: Riboswitches are regulatory ribonucleic acid (RNA) elements that act as ligand-dependent conformational switches that recognize their cognate ligand via a binding pocket located in their aptamer domain. In the apo form, the aptamer domain is dynamic, requiring an ensemble representation of its structure. Here, as a proof-of-concept, we used solvent accessibility information to construct a pair of dynamical ensembles of the aptamer domain of the well-studied S-adenosylmethionine (SAM) class-I riboswitch in the absence (−SAM) and presence (+SAM) of SAM....
