In this study, we focused on two pathways of cardiomyocytes or heart cells: the Hippo pathway, which is involved in stopping renewal of adult cardiomyocytes, and the dystrophin glycoprotein complex (DGC) pathway, essential for cardiomyocyte normal functions." Previous work had hinted that components of the DGC pathway may somehow interact with members of the Hippo pathway. The researchers genetically engineered mice to lack genes involved in one or both pathways, and then determined the ability of the heart to repair an injury. These studies showed for the first time that dystroglycan 1, a component of the DGC pathway, directly binds to Yap, part of the Hippo pathway, and that this interaction inhibited cardiomyocyte proliferation. "The discovery that the Hippo and the DGC pathways connect in the cardiomyocyte and that together they act as 'brakes,' or stop signals to cell proliferation, opens the possibility that by disrupting this interaction one day it might be possible to help adult cardiomyocytes proliferate and heal injuries caused by a heart attack, for example." Young at Heart: Restoring Cardiac Function with a Matrix Molecule Heart disease remains the leading cause of death worldwide, yet the few available treatments are still mostly unsuccessful once the heart tissue has suffered damage. Mammalian hearts are actually able to regenerate and repair damage - but only up to around the time of birth. Afterward, that ability disappe...

Authors: Kallam A, Armitage JO Abstract INTRODUCTION: T cell lymphomas are a heterogeneous group, with varying incidences, geographic patterns, and risk factors. Although until recently approached in a manner similar to B cell lymphomas, the treatment outcomes are poor and this disease is characterized by high relapse rates. The treatment advances in PTCL have been slow compared to B cell lymphomas. The outcomes of patients who progress following stem cell transplantation are worse. AREAS COVERED: This review focuses on the novel targeted agents that are approved and/or are under investigation for patients with...

Authors: Perez BA, Slover J, Edusei E, Horan A, Anoushiravani A, Kamath AF, Nelson CL Abstract BACKGROUND: Total joint arthroplasty is one of the most common surgeries performed in the United States with total knee arthroplasty (TKA) being one of the most successful surgeries for restoring function and diminishing pain. Even with the demonstrated success of TKA and a higher prevalence of arthritis and arthritis related disability among minorities, racial and gender disparity remains a constant issue in providing care for the adult reconstruction patient. AIM: To assess the role of demographics and expectations ...

CONCLUSION: Mobile phones belonging to health care workers are frequently contaminated with pathogenic bacteria with the potential of transferring drug resistance to nosocomial pathogens. Studies investigating the relationship to surgical site infections need to be conducted. The concept of "mobile hygiene" involving the change of mobile covers, replacement of cracked screens or even wiping the phone with an alcohol swab could yield the cost-effective balance that contaminated cell phones deserve until they are established as a direct cause of surgical site infections.

Th17 cells (producing IL-17) and Th9 cells (producing IL-9) exhibit functional plasticity, and their role in tumorigenicity is controversial. Th17/IL-17 and Th9/IL-9 exhibit critical, but often opposing, roles in tumor progression. In this issue of the JCI, Salazar et al. show that while IL-17 and IL-9 induced distinct but complementary molecular pathways, both cytokines also induced epithelial-mesenchymal transition (EMT) in lung cancer cells and promoted metastatic spreading. A key question before us now is whether IL-9 and IL-17 contribute to tumor progression in a sequential and stage-specific manner within the tumor microenvironment.

Emerging immune therapy, such as with the anti–programmed cell death–1 (anti–PD-1) monoclonal antibody nivolumab, has shown efficacy in tumor suppression. Patients with terminal cancer suffer from cancer pain as a result of bone metastasis and bone destruction, but how PD-1 blockade affects bone cancer pain remains unknown. Here, we report that mice lacking Pdcd1 (Pd1−/−) demonstrated remarkable protection against bone destruction induced by femoral inoculation of Lewis lung cancer cells. Compared with WT mice, Pd1−/− mice exhibited increased baseline pain sensitivity, but the deve...
