β-Arrestin2 mediates progression of murine primary myelofibrosis.

Primary myelofibrosis is a myeloproliferative neoplasm associated with significant morbidity and mortality, for which effective therapies are lacking. β-Arrestins are multifunctional adaptor proteins involved in developmental signaling pathways. One isoform, β-arrestin2 (βarr2), has been implicated in initiation and progression of chronic myeloid leukemia, another myeloproliferative neoplasm closely related to primary myelofibrosis. Accordingly, we investigated the relationship between βarr2 and primary myelofibrosis. In a murine model of MPLW515L-mutant primary myelofibrosis, mice transplanted with donor βarr2-knockout (βarr2-/-) hematopoietic stem cells infected with MPL-mutant retrovirus did not develop myelofibrosis, whereas controls uniformly succumbed to disease. Although transplanted βarr2-/- cells homed properly to marrow, they did not repopulate long-term due to increased apoptosis and decreased self-renewal of βarr2-/- cells. In order to assess the effect of acute loss of βarr2 in established primary myelofibrosis in vivo, we utilized a tamoxifen-induced Cre-conditional βarr2-knockout mouse. Mice that received Cre (+) donor cells and developed myelofibrosis had significantly improved survival compared with controls. These data indicate that lack of antiapoptotic βarr2 mediates marrow failure of murine hematopoietic stem cells overexpressing MPLW515L. They also indicate that βarr2 is necessary for progression of primary myelofibrosis, suggesting that it may serve as a novel therapeutic target in this disease.

NCCN Guidelines Insights: Myeloproliferative Neoplasms, Version 2.2018.

Myeloproliferative neoplasms (MPNs) are a group of heterogeneous disorders of the hematopoietic system that include myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET). PV and ET are characterized by significant thrombohemorrhagic complications and a high risk of transformation to MF and acute myeloid leukemia. The diagnosis and management of PV and ET has evolved since the identification of mutations implicated in their pathogenesis. These NCCN Guideline Insights discuss the recommendations outlined in the NCCN Guidelines for the risk stratification, treatment, and special considerations for the management of PV and ET.

WT1 vaccination in acute myeloid leukemia: new methods of implementing adoptive immunotherapy.

INTRODUCTION: The Wilms tumor 1 (WT1) gene was originally identified as a tumor suppressor gene that, when mutated, would lead to the development of pediatric renal tumors. More recently, it has been determined that WT1 is overexpressed in 90% of patients with acute myeloid leukemia (AML) and is mutated in approximately 10% of AML patients. WT1 plays a role in normal hematopoiesis and, in AML specifically, it has oncogenic function and plays an important role in cellular proliferation and differentiation. The ubiquity of WT1 in leukemia has lead to the development of vaccines aimed at employing the host immune system to mount a T-cell response to a known antigen. AREAS COVERED: In this evaluation, the authors discuss the role of WT1 in normal hematopoiesis as well as in the development of hematologic malignancies. Furthermore, the authors discuss the data supporting the development of WT1 vaccines, and the clinical trials supporting their use in patients with acute leukemia. EXPERT OPINION: Several small trials have been conducted which support the safety and efficacy of this therapy, although larger trials are certainly warranted. In the authors' opinion, the WT1 vaccination has potential in terms of its application as an adjuvant therapy for patients with AML who are at high risk of relapse or who have detectable minimal residual disease after initial standard therapy.

Hypercholesterolemia and prostate cancer: a hospital-based case-control study.

OBJECTIVE: High levels of serum cholesterol have been proposed to increase the risk of prostate cancer but the epidemiologic evidence is limited. METHODS: We conducted a hospital-based case-control study in Fargo, ND, USA, to examine the association between hypercholesterolemia and prostate cancer. Cases were men with incident, histologically confirmed prostate cancer. Controls were men without clinical cancer who were seen at the same hospital for an annual physical exam. Demographic and clinical data were abstracted from patients' medical charts. RESULTS: From a patient population aged 50 to 74 years old, we obtained data on 312 White cases and 319 White controls. Hypercholesterolemia was defined as total cholesterol greater than 5.17 (mmol/l). Univariate logistic regression showed a significant association between hypercholesterolemia and prostate cancer (odds ratio (OR) = 1.64, 95% confidence interval (CI): 1.19-2.27). This association changed only slightly after adjustment for age, family history of prostate cancer, body mass index, type 2 diabetes, smoking, and multivitamin use (OR = 1.58, 95% CI: 1.11-2.24). A significant association was found between low HDL and prostate cancer (OR = 1.57, 95% CI: 1.04-2.36). High LDL was associated with a 60% increased risk for prostate cancer (OR = 1.60, 95% CI: 1.09-2.34). Compared to never smokers, current smokers had an 84% increased risk for prostate cancer (OR = 1.84, 95% CI: 1.09-3.13). CONCLUSION: This study adds to recent evidence that hypercholesterolemia may increase the risk of prostate cancer in white men.
