Spleen endothelial cells from patients with myelofibrosis harbor the JAK2V617F mutation
In conclusion, we provide evidence that some ECs from the spleen and splenic veins of patients with MF bear the JAK2V617F mutation. We suggest that splenic ECs are involved in the process of malignant transformation in MF.

Heat shock protein 70 regulates Tcl1 expression in leukemia and lymphomas
T-cell leukemia/lymphoma 1 (TCL1) is an oncogene overexpressed in T-cell prolymphocytic leukemia and in B-cell malignancies including B-cell chronic lymphocytic leukemia and lymphomas. To date, only a limited number of Tcl1-interacting proteins that regulate its oncogenic function have been identified. Prior studies used a proteomic approach to identify a novel interaction between Tcl1 with Ataxia Telangiectasia Mutated. The association of Tcl1 and Ataxia Telangiectasia Mutated leads to activation of the NF-B pathway. Here, we demonstrate that Tcl1 also interacts with heat shock protein (Hsp) 70. The Tcl1-Hsp70 complex was...

The constitutive androstane receptor is a novel therapeutic target facilitating cyclophosphamide-based treatment of hematopoietic malignancies
In this study, we have developed a unique human primary hepatocyte (HPH)–leukemia cell coculture model; the chemotherapeutic effects of CPA on leukemia cells can be directly investigated in vitro in a cellular environment where hepatic metabolism was well maintained. Our results demonstrated that activation of CAR preferentially induces the expression of CYP2B6 over CYP3A4 in HPHs, although endogenous expression of these enzymes in leukemia cells remains negligible. Importantly, coadministration of CPA with a human CAR activator led to significantly enhanced cytotoxicity in leukemia cells by inducing the apoptosis pa...

WT1-specific T-cell responses in high-risk multiple myeloma patients undergoing allogeneic T cell-depleted hematopoietic stem cell transplantation and donor lymphocyte infusions
We examined the significance of WT1-CTL responses in patients with relapsed MM and high-risk cytogenetics who were undergoing allogeneic T cell–depleted hematopoietic stem cell transplantation (alloTCD-HSCT) followed by donor lymphocyte infusions. Of 24 patients evaluated, all exhibited WT1-CTL responses before allogeneic transplantation. These T-cell frequencies were universally correlated with pretransplantation disease load. Ten patients received low-dose donor lymphocyte infusions beginning 5 months after transplantation. All patients subsequently developed increments of WT1-CTL frequencies that were associated w...

Inositol tetrakisphosphate limits NK cell effector functions by controlling PI3K signaling
Natural killer (NK) cells have important functions in cancer immunosurveillance, BM allograft rejection, fighting infections, tissue homeostasis, and reproduction. NK cell–based therapies are promising treatments for blood cancers. Overcoming their currently limited efficacy requires a better understanding of the molecular mechanisms controlling NK cell development and dampening their effector functions. NK cells recognize the loss of self-antigens or up-regulation of stress-induced ligands on pathogen-infected or tumor cells through invariant NK cell receptors (NKRs), and then kill such stressed cells. Two second-me...

Systemic delivery of a TLR7 agonist in combination with radiation primes durable antitumor immune responses in mouse models of lymphoma
Passive immunotherapy with monoclonal antibodies has improved outcome for patients with B-cell malignancies, although many still relapse and little progress has been made with T-cell malignancies. Novel treatment approaches are clearly required in this disease setting. There has been much recent interest in developing therapeutic approaches to enhance antitumor immune responses using novel immunomodulatory agents in combination with standard of care treatments. Here we report that intravenous administration of the Toll-like receptor 7 (TLR7) agonist, R848 in combination with radiation therapy (RT), leads to the longstandin...

Clinical significance of overexpressed cyclin‐dependent kinase subunits 1 and 2 in esophageal carcinoma
Summary The mammalian cyclin‐dependent kinase subunit (Cks) family has two members, Cks1 and Cks2. Overexpression of Cks1 and Cks2 has been reported to be associated with high aggressiveness and poor prognosis in several malignancies, including prostate and hepatocellular carcinomas. However, whether Cks1 and Cks2 are overexpressed in esophageal carcinoma remains uncharacterized. To investigate whether overexpression of the Cks family is clinically relevant in esophageal carcinoma, and whether expression patterns of Cks1 and Cks2 can serve as biomarkers for esophageal carcinoma. Real‐time quantitative reverse transcrip...

Clinical characteristics of IPMN manifesting as acute pancreatitis or acute recurrent pancreatitis
ConclusionsAP/ARP caused by IPMN was of infrequent occurrence. AP/ARP caused by IPMN occurred more frequently in the main‐duct/combined type than in the branch‐duct type. Most cases were mild in severity and benign in histopathology. AP/ARP can be an initial manifestation of IPMN, though uncommon, which leads to diagnosis.

Is the cardiovascular system a therapeutic target for cannabidiol?
Cannabidiol (CBD) has beneficial effects in disorders as wide ranging as diabetes, Huntington's disease, cancer and colitis. Accumulating evidence now also suggests that CBD is beneficial in the cardiovascular system. CBD has direct actions on isolated arteries, causing both acute and time‐dependent vasorelaxation. In vitro incubation with CBD enhances the vasorelaxant responses in animal models of impaired endothelium‐dependent vasorelaxation. CBD protects against the vascular damage caused by a high glucose environment, inflammation or the induction of type 2 diabetes in animal models and reduces the vascular hyperpe...

Oncological Advantages of Oncoplastic Breast‐Conserving Surgery in Treatment of Early Breast Cancer
Abstract The standard approach to breast‐conserving surgery is wide local excision of the tumor and radiotherapy. However, a significant number of patients require further surgery to obtain oncologically clear margins, and may obtain a poor cosmetic result following adjuvant radiotherapy. Oncoplastic techniques may result in improved cosmesis, but few studies have investigated the oncological advantage of this approach. The aim of this retrospective study was to compare tumor clearance and the need for further margin excision following standard wide local excision (group A, 121 patients), and oncoplastic breast‐conserv...

Foxp3+ regulatory T cells coexisting with cancer associated fibroblast are correlated with a poor outcome in lung adenocarcinoma
Summary Recently, an association between tumor infiltrating Foxp3+ regulatory T cells (Tregs) and an unfavorable prognosis has been clinically shown in some cancers, but the mechanism of Treg induction in the tumor microenvironment remains uncertain. The aims of the present study were to examine the relationship between Tregs and the patient outcome and to investigate whether Treg induction is influenced by the characteristics of cancer‐associated fibroblasts (CAFs) in lung adenocarcinoma. The numbers of Tregs in both the tumor stroma and the tumor nest were counted in 200 consecutive pathological stage I lung invasive a...

Low cyclin F expression in hepatocellular carcinoma associates with poor differentiation and unfavorable prognosis
In this study, we showed that cyclin F was noticeably decreased in 16 pairs of tissue samples of hepatocellular carcinoma (HCC), compared to paracarcinoma tissues, at both mRNA and protein levels. Immunohistochemical staining data revealed that in 71.8% (176/245) of HCC cases, cyclin F expression in tumor tissue was much lower than that in nontumorous tissue. Low cyclin F expression, defined by receiver operating characteristic curve (ROC) analysis, was present in 69.0% of HCC patients. Low expression of cyclin F significantly correlated with tumor size, clinical stage, serum AFP level and tumor multiplicity. Further study...

Functional significance of erythropoietin in renal cell carcinoma
One of the molecules regulated by the transcription factor, hypoxia inducible factor (HIF), is the hypoxia-responsive hematopoietic factor, erythropoietin (EPO). This may have relevance to the development of renal cell carcinoma (RCC), where mutations of the von Hippel-Lindau (VHL) gene are major risk factors for the development of familial and sporadic RCC. VHL mutations up-regulate and stabilize HIF, which in turn activates many downstream molecules, including EPO, that are known to promote angiogenesis, drug resistance, proliferation and progression of solid tumours. HIFs typically respond to hypoxic cellular environmen...

Consistent performance measurement of a system to detect masses in mammograms based on blind feature extraction
Conclusions: Considering the heterogeneity in the datasets used to train and test our system in each case, we think that the variation of performance obtained when the results are compared with the overall results is acceptable in both cases, for NN and SVM classifiers. The present method is therefore very general in that it is able to adapt to different clinical situations and provide consistent performance.

Ki‐67, mini‐chromosome maintenance 2 protein (MCM2) and geminin have no independent prognostic relevance for cancer‐specific survival in surgically treated squamous cell carcinoma of the penis
Conclusions At present, conventional histopathological criteria remain the most powerful predictors of CSS in surgically treated SCCP. Due to overlapping staining profiles, Ki‐67, MCM2 and geminin, either singly or in various combinations, failed to immunohistochemically refine the boundaries between Broders' grading categories. Ki‐67, MCM2 and geminin do not represent independent prognostic parameters but reflect a more aggressive behaviour in surgically treated SCCP. Further studies are needed to clarify the currently contradictory predictive role of proliferation‐associated biomarkers in terms of predicting nodal ...

Bone marrow mesenchymal stem cells increase motility of prostate cancer cells via production of stromal cell‐derived factor‐1α
Abstract Prostate cancer frequently metastasizes to the bone, and the interaction between cancer cells and bone microenvironment has proven to be crucial in the establishment of new metastases. Bone marrow mesenchymal stem cells (BM‐MSCs) secrete various cytokines that can regulate the behaviour of neighbouring cell. However, little is known about the role of BM‐MSCs in influencing the migration and the invasion of prostate cancer cells. We hypothesize that the stromal cell‐derived factor‐1α released by BM‐MSCs may play a pivotal role in these processes. To study the interaction between factors secreted by BM‐...
