Lymphatic leakage can be seen as a detrimental phenomenon associated with fluid retention and deposition as well as gain of weight. Moreover, lymphatic dysfunction is associated with an inflammatory environment and can be a substrate for other health conditions. A number of treatments can ameliorate lymphatic vasculature: natural substances have been used as treatment options particularly suitable for their consolidated effectiveness and safety profile. Here we report the protective effect of AdipoDren®, an association of a series of plant-derived natural complexes, on lymphatic endothelium permeability promoted by interleukin-1 beta (IL-1β) and the associated molecular mechanisms...

REVIEW
Ming Pei
Adult stem cells are a promising cell source for cartilage regeneration. Unfortunately, due to donor age and ex vivo expansion, stem cell senescence becomes a huge hurdle for these cells to be used clinically. Increasing evidence indicates that environmental preconditioning is a powerful approach in promoting stem cells' ability to resist a harsh environment post-engraftment, such as hypoxia and inflammation. However, few reports organize and evaluate the literature regarding the rejuvenation effect of environmental preconditioning on stem cell proliferation and chondrogenic differentiation capacity, which are important variables for stem cell based tissue regeneration...

It has been known for many years that centromeres cluster at the spindle pole body in fission yeast. In this issue of Developmental Cell, Fernández-Álvarez et al. (2016) reveal that the functional significance of clustering is to promote spindle assembly by modulating nuclear envelope integrity at the onset of mitosis.

Enhancers regulate the expression of target genes across large genomic distances, but it is unclear how recently discovered topological domains affect this regulation. Reporting in this issue of Developmental Cell, Symmons et al. (2016) show that the endogenous Shh topological domain promotes functional interactions between Shh and its remote enhancer.

Increasing energy expenditure through brown adipocyte recruitment is a promising approach to combat obesity. We report here the comprehensive profiling of the epigenome and transcriptome throughout the lineage commitment and differentiation of C3H10T1/2 mesenchymal stem cell line into brown adipocytes. Through direct comparison to datasets from differentiating white adipocytes, we systematically identify stage- and lineage-specific coding genes, lncRNAs and microRNAs. Utilizing chromatin state maps, we also define stage- and lineage-specific enhancers, including super-enhancers, and their associated transcription factor binding motifs and genes...

Axon injury can lead to several cell survival responses including increased stability and axon regeneration. Using an accessible Drosophila model system, we investigated the regulation of injury responses and their relationship. Axon injury stabilizes the rest of the cell, including the entire dendrite arbor. After axon injury we found mitochondrial fission in dendrites was upregulated, and that reducing fission increased stabilization or neuroprotection (NP). Thus axon injury seems to both turn on NP, but also dampen it by activating mitochondrial fission...

BACKGROUND: As test and treat rolls out, effective interventions are needed to address the determinants of outcomes across the HIV treatment continuum and ensure that people infected with HIV are promptly tested, initiate treatment early, adhere to treatment, and are virally suppressed. Communication approaches offer viable options for promoting relevant behaviors across the continuum. CONCEPTUAL FRAMEWORK: This article introduces a conceptual framework, which can guide the development of effective health communication interventions and activities that aim to impact behaviors across the HIV treatment continuum in low- and medium-income countries...

Health communication is a broad term that applies to the fundamental need for practitioners, policy makers, patients, and community members to understand one another around health promotion and health care issues. Whether in a consultation between nurse and patient, a health clinic director's engagement with the health ministry, or a community campaign for encouraging HIV testing, all have critical health communication elements. When people's needs are not perceived by them to be addressed or clients/patients do not understand what is being communicated, they are unmotivated to engage...

Wnt/β-catenin signal is required in bone formation and remodling, but little is known about whether Wnt/β-catenin signal could promote osteogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs) after uniaxial mechanical stretch. In this study, rat BMSCs were identified by flow cytometry and used for mechanical stretch. A custom-made uniaxial dynamic stretch apparatus was applied for rat BMSCs stretch. There were 2 groups in the study: the mechanical stretch group and the nonstretch control group...

BACKGROUND: Stress is a potent immunomodulator contributing to chronic conditions. Chronic graft-versus-host disease (cGVHD) is a life-threatening late effect of allogeneic hematopoietic cell transplantation associated with stress and exaggerated immune response that may be associated to lifestyle behaviors. OBJECTIVE: The aim of this study is to explore associations among lifestyle behaviors, perceived stress, and inflammation of individuals with cGVHD. METHODS: A secondary analysis from a prospective observational study of 24 adults (≥18 years) with cGVHD was conducted...

Mechanical circulatory support using left ventricular assist devices (LVADs) has been demonstrated to improve survival in patients with advanced heart failure. LVAD therapy also promotes reverse ventricular remodeling, which in some cases has led to sufficient myocardial recovery to allow LVAD removal. Identification of suitable patients for LVAD removal however remains challenging. We investigated the hypothesis that invasive assessment of exercise hemodynamics may provide additional information in relation to the assessment of contractile reserve in potential candidates for LVAD explant...

In most eukaryotic cells mitochondria are essential organelles involved in a great variety of cellular functions. One of the physiological processes linked to mitochondria is aging, a gradual process of damage accumulation that eventually promotes cell death. Aging depends on a balance between mitochondrial biogenesis, function and degradation. It has been previously shown that Tor1, Sch9 and Ras2 are activated in response to nutrient availability and regulate cell growth and division. A deficiency in any of these genes promotes lifespan extension and cell protection during oxidative and heat shock stress...

Cellular senescence is a stable cell cycle arrest that is the causative process of aging. The PI3K/AKT/mTOR pathway is implicated in the control of cellular senescence and inhibitors of this pathway have been successfully used for life span prolongation experiments in mammals. PTEN is the major regulator of the PI3K/AKT/mTOR pathway and loss of PTEN promotes a senescence response termed PICS. Here we report a novel-screening assay, for the identification of compounds that block different types of senescence response...
