Promoting a MOSAIC future in science.

Discoveries at the frontiers of science and finding solutions to pressing biomedical problems will be accelerated when talent, which is widely distributed, is better aligned with opportunities. Strategies to enhance a MOSAIC (Maximizing Opportunities for Scientific and Academic Independent Careers) professoriate and diversify the biomedical landscape are discussed.

Evolution of a self-renewing, participant-centered workshop series in BMB assessment.

We present as a case study the evolution of a series of participant-centered workshops designed to meet a need in the life sciences education community-the incorporation of best practices in the assessment of student learning. Initially, the ICABL (Inclusive Community for the Assessment of Biochemistry and Molecular Biology/BMB Learning) project arose from a grass-roots effort to develop material for a national exam in biochemistry and molecular biology. ICABL has since evolved into a community of practice in which participants themselves-through extensive peer review and reflection-become integral stakeholders in the workshops. To examine this evolution, this case study begins with a pilot workshop supported by seed funding and thoughtful programmatic assessment, the results of which informed evidence-based changes that, in turn, led to an improved experience for the community. Using participant response data, the case study also reveals critical features for successful workshops, including participant-centered activities and the value of frequent peer review of participants' products. Furthermore, we outline a train-the-trainer model for creating a self-renewing community by bringing new perspectives and voices into an existing core leadership team. This case study, then, offers a blueprint for building a thriving, evolving community of practice that not only serves the needs of individual scientist-educators as they seek to enhance student learning, but also provides a pathway for elevating members to positions of leadership.

Report of the 2018-2019 Research and Graduate Affairs Committee.

The 2018-2019 Research and Graduate Affairs Committee (RGAC) was charged with critically evaluating the leadership development support necessary for pharmacy researchers, including postdoctoral trainees, to develop the skills needed to build and sustain successful research programs and analyzing how well those needs are being met by existing programs both within AACP and at other organizations. The RGAC identified a set of skills that could reasonably be expected to provide the necessary foundation to successfully lead a research team and mapped these skills to the six domains of graduate education in the pharmaceutical sciences established by the 2016-2017 RGAC (Table 1). In addition, the RGAC identified competency in team science and the bench-to-bedside-to-beyond translational spectrum as being critical elements of research leadership. The universality of these skills and their value prompted the RGAC to make two related recommendations to AACP: [Table: see text] Recommendation 1: AACP should promote the development and use of strategies to ensure intentional and ongoing professional development, such as Individual Development Plans. Recommendation 2: AACP should explore collaborative research leadership development opportunities between faculty at research-intensive institutions and faculty at non-research-intensive institutions. The RGAC also examined programs available at AACP and other national organizations that could help pharmacy faculty develop foundational skills for research leadership (Table 2). The RGAC administered two surveys, one to administrators responsible for research at colleges and schools of pharmacy and one to faculty members at pharmacy schools, to gather information about training needs, programming and support available for research leadership development. Administrators and faculty agreed that research is important for career advancement for faculty, and almost all administrators reported their schools provide funds, release time and mentoring for participation in research career development. However, a lack of faculty awareness regarding programs and available support may be a barrier to participation. The RGAC therefore makes two recommendations and one suggestion related to AACP programming: [Table: see text] Recommendation 3: AACP should expand research leadership development opportunities building from existing programs such as ALFP and AACP Catalyst, with consideration placed on developing programs that promote collaborative research. Recommendation 4: AACP should collaborate with other professional organizations to expand research leadership development opportunities across the academy. Suggestion 1: Colleges and schools of pharmacy should take a proactive role in promoting and facilitating research leadership development for faculty. The RGAC separately examined the research leadership development needs of postdoctoral trainees, recognizing the distinct needs of trainees along the PhD or PhD/PharmD, PharmD/fellowship, and PharmD/residency paths. A review of organizational resources and opportunities for post-doctoral trainees available from national organizations, including AACP, was undertaken (Table 5). The RGAC sees an opportunity for AACP to foster research development of those trainees whose career track will likely be in clinical practice and makes one recommendation and one suggestion related to postdoctoral trainees: Recommendation 5: AACP should support and/or develop programs and activities for pharmacy residents seeking to transition into faculty positions to acquire the skills necessary to develop and lead research programs. Suggestion 2: Colleges and schools of pharmacy should include postdoctoral trainees with academic interests in research leadership development opportunities available to junior faculty. In addition, the RGAC proposed one policy statement that was adopted July 2019 by the AACP House of Delegates: Policy Statement: AACP recognizes the positive role that research leadership development can play in the success of early and mid-career faculty.

Breaking Down Barriers to Pharmacy Graduate Education: The Report of the 2017-2018 Research and Graduate Affairs Committee.

EXECUTIVE SUMMARY The 2017-2018 Research and Graduate Affairs Committee (RGAC) was given three charges aimed at helping academic pharmacy address barriers that must be overcome by both students and schools to attract, retain, and support the development of a diverse, well-rounded, and successful graduate student population. These charges were (1) identifying teaching methodologies, tools and opportunities that graduate programs can introduce into curriculum to overcome barriers to success of today's and tomorrow's learners; (2) developing a strategy for achieving member support of the 2016-2017 recommended graduate competencies by identifying gaps in and existing examples of courses or opportunities that achieve competency-based pharmacy graduate education; and (3) identifying potential strategies to address identified barriers to pursuing graduate education, especially among under-represented student populations. This report describes attitudes toward and opportunities related to competency-based education in graduation education in colleges and schools of pharmacy, identifies types of tools schools could use to enhance training towards the competency framework developed by the 2016-2017 RGAC, particularly with regards to the so-called power skills, and outlines a role for AACP in facilitating this training. This report also considers a number of barriers, both perceived and real, that potential students encounter when considering graduate training and suggests strategies to understand the impact of and mitigate these barriers. To strengthen competency-based graduate education, the RGAC puts forth two recommendations that AACP develop a toolkit supporting the training of power skills and that AACP should develop or curate programs or tools to support the use of individual development plans (IDPs). The RGAC also puts forth a suggestion to schools that IDPs be implemented for all students. In considering the barriers to pursuing graduate education, the Committee proposes one policy statement that AACP supports the training and development of an increasingly diverse population of researchers at pharmacy schools through active efforts to promote M.S. and Ph.D. education along with Pharm.D. education. Additionally, the Committee provides recommendations that AACP should expand its efforts in career tracking of graduate students to include collection and/or analysis of data that could inform the Academy's understanding of barriers to pursuing graduate education in pharmacy schools, the AACP Office of Institutional Research and Effectiveness should expand upon graduate program data described in the annual Profile of Pharmacy Students report, and finally that AACP should include graduate programs in efforts to increase diversity of students at pharmacy schools.

Competency, Programming, and Emerging Innovation in Graduate Education within Schools of Pharmacy: The Report of the 2016-2017 Research and Graduate Affairs Committee.

Graduate education in the pharmaceutical sciences is a cornerstone of research within pharmacy schools. Pharmaceutical scientists are critical contributors to addressing the challenges of new drug discovery, delivery, and optimal care in order to ensure improved therapeutic outcomes in populations of patients. The American Association of Colleges of Pharmacy (AACP) charged the 2016-2017 Research and Graduate Affairs Committee (RGAC) to define the competencies necessary for graduate education in the pharmaceutical sciences (Charge 1), recommend collaborative curricular development across schools of pharmacy (Charge 2), recommend AACP programing for graduate education (Charge 3), and provide guidance on emerging areas for innovation in graduate education (Charge 4). With respect to Charges 1 and 2, the RGAC committee developed six domains of core competencies for graduate education in the pharmaceutical sciences as well as recommendations for shared programming. For Charge 3, the committee made 3 specific programming recommendations that include AACP sponsored regional research symposia, a professional development forum at the AACP INterim Meeting, and the addition of a graduate research and education poster session at the AACP Annual Meeting. For Charge 4, the committee recommended that AACP develop a standing committee of graduate program deans and directors to provide guidance to member schools in support of graduate program representation at AACP meetings, develop skills for interprofessional teamwork and augment research through integration of Pharm.D., Ph.D., postdoctoral associates, resident, and fellow experiences. Two proposed policy statements by the committee are that AACP believes core competencies are essential components of graduate education and AACP supports the inclusion of research and graduate education focuses in its portfolio of meetings and programs.

Genome-wide positioning of bivalent mononucleosomes.

BACKGROUND: Bivalent chromatin refers to overlapping regions containing activating histone H3 Lys4 trimethylation (H3K4me3) and inactivating H3K27me3 marks. Existence of such bivalent marks on the same nucleosome has only recently been suggested. Previous genome-wide efforts to characterize bivalent chromatin have focused primarily on individual marks to define overlapping zones of bivalency rather than mapping positions of truly bivalent mononucleosomes. RESULTS: Here, we developed an efficacious sequential ChIP technique for examining global positioning of individual bivalent nucleosomes. Using next generation sequencing approaches we show that although individual H3K4me3 and H3K27me3 marks overlap in broad zones, bivalent nucleosomes are focally enriched in the vicinity of the transcription start site (TSS). These seem to occupy the H2A.Z nucleosome positions previously described as salt-labile nucleosomes, and are correlated with low gene expression. Although the enrichment profiles of bivalent nucleosomes show a clear dependency on CpG island content, they demonstrate a stark anti-correlation with methylation status. CONCLUSIONS: We show that regional overlap of H3K4me3 and H3K27me3 chromatin tend to be upstream to the TSS, while bivalent nucleosomes with both marks are mainly promoter proximal near the TSS of CpG island-containing genes with poised/low expression. We discuss the implications of the focal enrichment of bivalent nucleosomes around the TSS on the poised chromatin state of promoters in stem cells.

Association of OLE RNA with bacterial membranes via an RNA-protein interaction.

Ornate, large, extremophilic (OLE) RNAs are large, non-coding transcripts characterized by their ornate secondary structure and presence predominantly in Gram-positive, extremophilic bacteria. A gene for an OLE-associated protein (OAP) is almost always located immediately downstream of the OLE gene. OAP has no extensive homology to other proteins and is predicted to form multiple transmembrane domains. We show that this protein forms a ribonucleoprotein complex with OLE RNA using at least 2:1 protein : RNA stoichiometry. A series of truncated OLE RNA constructs was used to establish that most of the RNA can be deleted without eliminating protein binding. Two primary binding sites are present within the RNA, although additional binding determinants exist and extensive structural stabilization is induced by OAP. RNA fluorescence in situ hybridization (FISH) was used in Escherichia coli to demonstrate that ribonucleoprotein complex formation localizes the RNA near cell membranes of this heterologous system. Therefore, the majority of the complex structure formed by OLE RNA may perform a biochemical function that requires membrane localization.

Evidence for widespread gene control function by the ydaO riboswitch candidate.

Nearly all representatives of experimentally validated riboswitch classes in bacteria control the expression of genes for the transport or synthesis of key metabolic compounds. Recent findings have revealed that some riboswitches also regulate genes involved in physiological changes, virulence, and stress responses. Many novel RNA motifs are being identified by using bioinformatics algorithms that search for conserved sequence and structural features located in intergenic regions. Some of these RNAs are likely to function as riboswitches for metabolites or signaling compounds, and confirmation of this function would reveal the basis of the genetic control of new regulons. Herein we describe the analysis of the ydaO riboswitch candidate, which represents one of the most widespread candidates remaining to be validated. These RNAs are common in Gram-positive bacteria, and their genomic associations with diverse genes suggest that they sense a compound that signals broader physiological changes. We determined that the ydaO motif exhibits sequence- and structure-dependent gene control, and reporter assays indicate that its natural ligand is present even when cells are grown in defined media. A transposon-mediated knockout screen resulted in mutants with a dysregulated expression of genes controlled by the RNA motif. The mutations disrupt genes that drastically modulate energy-generating pathways, suggesting that the intracellular concentration of the ligand sensed by the ydaO motif is altered under these stress conditions.

Identification of 22 candidate structured RNAs in bacteria using the CMfinder comparative genomics pipeline.

We applied a computational pipeline based on comparative genomics to bacteria, and identified 22 novel candidate RNA motifs. We predicted six to be riboswitches, which are mRNA elements that regulate gene expression on binding a specific metabolite. In separate studies, we confirmed that two of these are novel riboswitches. Three other riboswitch candidates are upstream of either a putative transporter gene in the order Lactobacillales, citric acid cycle genes in Burkholderiales or molybdenum cofactor biosynthesis genes in several phyla. The remaining riboswitch candidate, the widespread Genes for the Environment, for Membranes and for Motility (GEMM) motif, is associated with genes important for natural competence in Vibrio cholerae and the use of metal ions as electron acceptors in Geobacter sulfurreducens. Among the other motifs, one has a genetic distribution similar to a previously published candidate riboswitch, ykkC/yxkD, but has a different structure. We identified possible non-coding RNAs in five phyla, and several additional cis-regulatory RNAs, including one in epsilon-proteobacteria (upstream of purD, involved in purine biosynthesis), and one in Cyanobacteria (within an ATP synthase operon). These candidate RNAs add to the growing list of RNA motifs involved in multiple cellular processes, and suggest that many additional RNAs remain to be discovered.

Tandem riboswitch architectures exhibit complex gene control functions.

Riboswitches are structured RNAs typically located in the 5' untranslated regions of bacterial mRNAs that bind metabolites and control gene expression. Most riboswitches sense one metabolite and function as simple genetic switches. However, we found that the 5' region of the Bacillus clausii metE messenger RNA includes two riboswitches that respond to S-adenosylmethionine and coenzyme B12. This tandem arrangement yields a composite gene control system that functions as a two-input Boolean NOR logic gate. These findings and the discovery of additional tandem riboswitch architectures reveal how simple RNA elements can be assembled to make sophisticated genetic decisions without involving protein factors.
