UNDERSTANDING UO BY MODELING ELECTRONIC AND VIBRATIONAL SPECTROSCOPY
Author Institution: The Ohio State University, Columbus, OH 43210; University of Tennessee, Knoxville, TN 37996Spin-orbit configuration interaction ({\it{SO-CI}}) continues to be a valuable electronic structure tool in understanding the electronic states of small actinide containing molecules. Recent interest has a variation of a familiar actinide molecule, UO. The additional electron would appear to be a simple alteration or perturbation to an understood system, but experimentally it presents some questions for theory to investigate. Principal questions involve characterization of the lowest electronic states in UO involves occupation of the either the 5f or the 5f non-bonding orbitals and some simple excitation generates a multitude of electronic states. Use of self-consistent field with improved virtual orbital calculations ({\it{SCF}}) will again be the foundation of the {\it{SO-CISD}} determination of the potential energy surfaces ({\it{PES}}) of the ground and low lying excited states of the UO molecule. {\it{PES}} evaluation will occur along the internal coordinates of and , and will be variationally fit to determine bound vibrational levels present within the ground and low-lying excited states. Vibrational and electronic energy levels should help clarify and describe new and interesting spectra and other properties. Gibson, J. K.; Haire, R. G.; Marcalo, J.; de Matos, A. P.; Mrozik, M.

Abstract 5643: Physical and functional interactions of exon-skipping variants of androgen receptor with the full-length counterpart
Abstract
The androgen receptor (AR) is arguably the critical driver of not only early but also advanced prostate cancer. The recent comprehensive splicing landscapes revealed that metastatic castration resistant prostate cancer harbors multiple forms of AR variants (AR-Vs), many of which have diverse patterns of inclusion/exclusion of exons (E4-8) corresponding to the ligand-binding domain. We had used AR-negative M12 prostate cancer cell line and recently reported characteristics of AR-Vs with respect to their subcellular localization and transcriptional activation on luciferase reporter driven by probasin-based promoter (AR2PB-luc)(1). While ARv5es is predominantly nuclear and constitutively active like well-documented ARv567es, many others are castration -induced variants are inactive. As many AR-Vs and the full-length AR (AR-FL) are co-expressed in the same cell, it is important to determine how these inactive AR-Vs interact with active AR including AR-FL. To this end, we examined two inactive AR-Vs namely v7es and v56es in relation to AR-FL. ARv7es, which skips exon 7, is predominantly localized in cytoplasm. ARv7es physically interacted with AR-FL. Moreover, nuclear accumulation of ARv7es was promoted by the addition of dihydrotestosterone (DHT) only in the presence of AR-FL, suggesting that ARv7es and AR-FL heterodimerize in the nuclear compartment. However, DHT-dependent transactivation of AR-FL was not affected by the presence of ARv7es. More specifically, in M12 cells, AR2PB-luc was transactivated by AR-FL to the similar extents either in the presence or absence of ARv7es. In addition, in doxycycline (Dox)-inducible ARv7es stable LNCaP cell line (LNCaP/ARv7es), the presence of ARv7es did not affect DHT-induced expression of endogenous PSA and NKX3.1 transcripts as well as transactivation of AR2PB-luc. In the similar setting, when we examined ARv56es which also physically interacted with AR-FL, Dox-induced expression of ARv56es in LNCaP/ARv56es was sufficient to induce expression of endogenous PSA and NKX3.1 transcripts. Further, DHT-induced expression of these transcripts was enhanced by ARv56es in LNCaP/ARv56es. Accordingly, we propose that AR-Vs display differential modes of action on AR-FL as exemplified by ARv7es as the bystander and v56es as the effector. 1. Oncogene (PMID: 27694897)

LASER SPECTROSCOPY OF UO: CHARACTERIZATION, LIGAND FIELD ASSIGNMENTS AND DEPERTURBATION ANALYSIS OF STATES IN THE 0-3 eV RANGE
Author Institution: Department of Chemistry, Emory University AtlantaWavelength-resolved fluorescence excitation techniques have been used to record thirty-three electronic transitions of UO at a resolution of . Nine low-lying electronic states that correlate with and were characterized. With few exceptions, assignments were unambiguously determined from observations of the first lines in at least two rotational branches. Deperturbed constants of and {\AA} have been determined for the ground state of the configuration, and and {\AA} for states of the configuration. Fitted values for the ligand field parameters . and strongly differ from their relativistic Dirac-Fock values: , and Ligand field theory calculations have been used in an attempt to provide configurational assignments for the excited states of UO. The energies of 23 electronic configurations of UO, and 19 electronic configurations of , have been calculated. The density distribution of bound states for UO and up to their ionization limits was also calculated
