Abstract
Implementation strategies for pharmacogenetic testing have been largely limited to major academic medical centers and large health systems, threatening to exacerbate healthcare disparities for rural and tribal populations. There exists a need in Montana (United States)-a state where two-thirds of the population live in rural areas and with a large proportion of tribal residents-to develop novel strategies to make pharmacogenetic testing more broadly available. We established partnerships between University of Montana (UM) and three early adopter sites providing patient-centered care to historically neglected populations. We conducted 45 semi-structured interviews with key stakeholders at each site and solicited participant feedback on the utility of a centralized pharmacogenetic service at UM offering consultations to patients and providers statewide via telehealth. For settings serving rural patients-tribal and non-tribal-participants described healthcare facilities without adequate infrastructure, personnel, and funding to implement pharmacogenetic services. Participants serving tribal communities stressed the need for ethical practices for collecting biospecimens and returning genetic results to patients, largely due to historical and contemporary traumas experienced by tribal populations with regard to genetic research. Participants expressed that pharmacogenetic testing could benefit patients by achieving therapeutic benefit sooner, reducing the risk of side effects, and improving adherence outcomes for patients with limited access to follow-up services in remote areas. Others expressed concern that financial barriers to pharmacogenetic testing for patients of lower socioeconomic status would further exacerbate inequities in care. Participants valued the role of telehealth to deliver pharmacogenetic consults from a centralized service at UM, describing the ability to connect providers and patients to resources and expertise as imperative to driving successful pharmacogenetic implementation. Our results support strategies to improve access to pharmacogenetic testing for neglected patient populations and create opportunities to reduce existing healthcare inequities. By exploring critical challenges for pharmacogenetic implementation focused on serving underserved communities, this work can help guide equitable frameworks to serve as a model for other resource-limited settings looking to initiate pharmacogenetic testing.

Abstract
INTRODUCTION Pharmacogenetics, in hand with precision medicine in oncology, represents an opportunity to holistically tailor a patient's treatment regimen using both somatic and germline variants to improve efficacy and decrease toxicity. Colorectal cancer patients represent a population with frequent use of fluoropyrimidine and irinotecan and are an ideal opportunity for implementation of preemptive pharmacogenetics as evidence supports pharmacogenetic testing for DPYD and UGT1A1 to reduce fluoropyrimidine and irinotecan toxicities. METHODS This was a single arm proof-of-concept study at a large community-based health system. Participants provided samples for pharmacogenetic testing via an external vendor prior to chemotherapy initiation and an oncology pharmacist was responsible for pharmacogenetic interpretation and pharmacogenetic-guided therapeutic recommendation to the treating provider. RESULTS A total of 24 (60%) participants had a UGT1A1 variant. All participants (100%) were DPYD*1/*1. Results were available and interpreted for 29/40 (72.5%) participants prior to scheduled chemotherapy initiation (p value <0.014). Of the participants whose results were available in 5 weekdays or less (n = 23), 20 (87%) were communicated with the treating provider prior to scheduled chemotherapy administration. A total turnaround time of 5 days or less was significantly associated with PGx feasibility in a community-based oncology clinic (p = 0.03). CONCLUSIONS In conclusion, we were able to show that implementation of preemptive pharmacogenetic testing into a community oncology clinic with results interpretation available prior to scheduled initiation of chemotherapy was feasible. As pharmacogenetic testing in oncology expands, pharmacists should be prepared to optimize supportive medication regimens as well as chemotherapy with pharmacogenetic results.

Abstract
Pharmacogenetic (PGx) literature has shown beneficial outcomes in safety, efficacy and cost when evidence-based gene-drug decision making is incorporated into clinical practice. PGx programs with successfully implemented clinical services have been published in a variety of settings including academic health centers and community practice. The primary objective was to systematically scope the literature to characterize the current trends, extent, range and nature of clinical PGx programs. Forty articles representing 19 clinical PGx programs were included in analysis. Most programs are in urban, academic institutions. Education, governance and workflow were commonly described while billing/reimbursement and consent were not. This review provides an overview of current PGx models that can be used as a reference for institutions beginning the implementation process.

Abstract
The North Carolina Precision Health Collaborative is an interdisciplinary, public-private consortium of precision health experts who strategically align statewide resources and strengths to elevate precision health in the state and beyond. Pharmacogenomics (PGx) is a key area of focus for the North Carolina Precision Health Collaborative. Experts from Atrium Health's Levine Cancer Institute, Duke University/Duke Health System, Mission Health and the University of North Carolina (UNC) at Chapel Hill/UNC Health System have collaborated since 2017 to implement strategic PGx initiatives, including basic sciences research, translational research and clinical implementation of germline testing into practice and policy. This institutional profile highlights major PGx programs and initiatives across these organizations and how the collaborative is working together to advance PGx science and implementation.

Abstract
BACKGROUND Semaphorin 3B (SEMA3B) is characterized as a strong suppressing factor of the proliferation of cancerous cells and also by its anti-angiogenic effect. However, the knowledge on the changes in the expression profile of SEMA3B under the influence of cisplatin in endometrial cancer remains fragmented. The aim of this work was to note the changes in expression of SEMA3B when under the influence of cisplatin in the endometrial cancer cell line. METHODS Ishikawa cell line cells were exposed to three different concentrations of cisplatin: 2.5μM; 5μM; 10μM for 12, 24 and 48 hours and were compared to cells untreated by the drug. Changes in the expression profile of SEMA3B were determined based upon RtqPCR (mRNA) alongside the ELISA assay (protein). The Statistica 13.0 PL program was used for statistical analysis (p<0.05). RESULTS Changes on the transcriptome level seem to be more dynamic than on the proteome level. Regardless of the concentration given or the exposition period, the expression of semaphorin 3B was, in fact, higher in cells exposed to cisplatin. Statistically substantial differences (p<0.05) in the expression of SEMA3B mRNA and protein were seen for all incubation periods at the given cisplatin level when compared to the control. CONCLUSION Cisplatin causes a growth in the expression of SEMA3B in an endometrial cancer cell culture, this results in the restoration in the state of cell homeostasis and shows the effectiveness of pharmacotherapy, including a low risk of drug resistance.
