The Role of Oncostatin M and Its Receptor Complexes in Cardiomyocyte Protection,Regeneration, and Failure

Oncostatin M (OSM), a member of the interleukin-6 family, functions as a major mediator of cardiomyocyte remodeling under pathological conditions. Its involvement in a variety of human cardiac diseases such as aortic stenosis, myocardial infarction, myocarditis, cardiac sarcoidosis, and various cardiomyopathies make the OSM receptor (OSMR) signaling cascades a promising therapeutic target. However, the development of pharmacological treatment strategies is highly challenging for many reasons. In mouse models of heart disease, OSM elicits opposing effects via activation of the type II receptor complex (OSMR/gp130). Short-term activation of OSMR/gp130 protects the heart after acute injury, whereas chronic activation promotes the development of heart failure. Furthermore, OSM has the ability to integrate signals from unrelated receptors that enhance fetal remodeling (dedifferentiation) of adult cardiomyocytes. Because OSM strongly stimulates the production and secretion of extracellular proteins, it is likely to exert systemic effects, which in turn, could influence cardiac remodeling. Compared with the mouse, the complexity of OSM signaling is even greater in humans because this cytokine also activates the type I leukemia inhibitory factor receptor complex (LIFR/gp130). In this article, we provide an overview of OSM-induced cardiomyocyte remodeling and discuss the consequences of OSMR/gp130 and LIFR/gp130 activation under acute and chronic conditions.     

IL-6 Cytokine Family: A Putative Target for Breast Cancer Prevention and Treatment

The IL-6 cytokine family is a group of signaling molecules with wide expression and function across vertebrates. Each member of the family signals by binding to its specific receptor and at least one molecule of gp130, which is the common transmembrane receptor subunit for the whole group. Signal transduction upon stimulation of the receptor complex results in the activation of multiple downstream cascades, among which, in mammary cells, the JAK-STAT3 pathway plays a central role. In this review, we summarize the role of the IL-6 cytokine family—specifically IL-6 itself, LIF, OSM, and IL-11—as relevant players during breast cancer progression. We have compiled evidence indicating that this group of soluble factors may be used for early and more precise breast cancer diagnosis and to design targeted therapy to treat or even prevent metastasis development, particularly to the bone. Expression profiles and possible therapeutic use of their specific receptors in the different breast cancer subtypes are also described. In addition, participation of these cytokines in pathologies of the breast linked to lactation and involution of the gland, as post-partum breast cancer and mastitis, is discussed.

支持IP漫游的多跳接入组网设计及协议扩展

针对现有固定宽带有线、无线接入技术存在的不足,本文结合Ad hoc技术和移动IP技术,提出了一种支持IP漫游的多跳接入方式,包括组网设计及协议扩展。其组网方式为：边缘接入采用多跳Ad hoc技术,主干接入采用分层移动IPv6技术。多跳Ad hoc网络大大增加了网络的覆盖范围,减轻了网络铺设成本,且支持宽带接入;分层移动IPv6降低了域内切换的信令开销和时延。同时,对现有的分层移动IPv6协议进行扩展,实现了主干网络与边缘多跳网络的有机结合。移动用户不但能以较低的信令开销实现全局的IP漫游,还能保证进入同一MANET网络中的移动节点直接通信,减轻了主干网络的传输负担,也保证了突发情况下节点能通过边缘MANET网络保持链路畅通。
