The liver is the organ that responds to nutritional disturbances including magnesium deficiency. The present study evaluated cellular responses to magnesium deficiency using model cells of the liver, namely, HepG2 cells as hepatocytes, RAW264.7 cells as Kupffer cells and human umbilical vein endothelial cells (HUVECs) as vascular endothelial cells; we examined effects of culture with magnesium deficient medium on cell responses in individual types of cells as well as interactive responses among cells. Metabolomic analyses indicated that magnesium deficiency differentially affected the cellular content of metabolites among HepG2 cells, RAW264...

In natural tissues, the nutrition of cells and removal of waste products is facilitated by a dense capillary network which is generated during development. This perfusion system is also indispensable for tissue formation in vitro. Nutrition depending solely on diffusion is not sufficient to generate tissues of clinically relevant dimensions, which is a core aim in tissue engineering research. In this study, the establishment of a vascular network was investigated in a self-assembling approach employing endothelial and mural cells...

Wound therapy remains a clinical challenge due to the complexity of healing pathology and high demand of achieving functional and aesthetically satisfactory scars. Newly formed blood vessels are essential for tissue repair since they can support cells at the wound site with nutrition and oxygen. In this study, we investigated the effects of Asperosaponin VI (ASA VI) isolated from a traditional Chinese medicine, the root of Dipsacus asper Wall, in promoting angiogenesis, as well as its function in wound therapeutics...

Vascular aging is an independent risk factor for age-related diseases, including atherosclerosis. Fibroblast growth factor 21 (FGF21) has been widely recognized as a metabolic regulator that is elevated in response to caloric and nutritional restrictions. Recent studies have demonstrated its emerging role as a pro-longevity hormone, but its effects on the senescence of human umbilical vascular endothelial cells (HUVECs) remain unclear. In the present study, we explored the anti-senescence effects and underlying mechanism of FGF21 on HUVECs...

After oncogenic transformation, tumor cells rewire their metabolism to obtain sufficient energy and biochemical building blocks for cell proliferation, even under hypoxic conditions. Glucose and glutamine become their major limiting nutritional demands. Instead of being autonomous, tumor cells change their immediate environment not only by their metabolites but also by mediators, such as juxtacrine cell contacts, chemokines and other cytokines. Thus, the tumor cells shape their microenvironment as well as induce resident cells, such as fibroblasts and endothelial cells (ECs), to support them...

The development of the ocular vasculatures is perfectly synchronized to provide the nutritional and oxygen requirements of the forming human eye. The fetal vasculature of vitreous, which includes the hyaloid vasculature, vasa hyaloidea propria, and tunica vasculosa lentis, initially develops around 4-6 weeks gestation (WG) by hemo-vasculogenesis (development of blood and blood vessels from a common progenitor, the hemangioblast). This transient fetal vasculature expands around 12 WG by angiogenesis (budding from primordial vessels) and remains until a retinal vasculature begins to form...

Kilmer S McCully
Many pathogenic microorganisms have been demonstrated in atherosclerotic plaques and in cerebral plaques in dementia. Hyperhomocysteinemia, which is a risk factor for atherosclerosis and dementia, is caused by dysregulation of methionine metabolism secondary to deficiency of the allosteric regulator, adenosyl methionine. Deficiency of adenosyl methionine results from increased polyamine biosynthesis by infected host cells, causing increased activity of ornithine decarboxylase, decreased nitric oxide and peroxynitrate formation and impaired immune reactions...

Vascular endothelial growth factor (VEGF) is a glycoprotein vital to the regulation of vascular endothelial cells proliferation, migration and angiogenesis. The expression of VEGF is required for the formation of new blood vessels critical in supplying oxygen and nutrition in the course of tumorigenesis. The present study investigated the effect of 5,6-dehydrokawain isolated from the rhizomes of Alpinia mutica on VEGF expression in vitro using HT-29 cell line. The results revealed that 5,6-dehydrokawain induced the expression of proangiogenic tumour-derived VEGF of HT-29 cells, which may explain the inability of 5,6-dehydrokawain in suppressing cancer cells proliferation...

In the process of enlarging of tumors, the dissolving tissue structures and remodeling endothelial cells for restoring gas exchange and nutritional support, further facilitate tumor cell invasion and metastasis. Activation of Ras plays a critical role in the development of esophageal squamous cell carcinoma (ESCC), but the underlying mechanisms remain poorly understood. We therefore investigated whether Ras guanyl-releasing protein 3 (RasGRP3), a Ras activator, could promote metastasis by inducing vascular regeneration and further epithelial-mesenchymal transition under nutrient stress (NS)...

The normal retinal development is interrupted by preterm birth and a retinopathy of prematurity (ROP) may develop as its consequence. ROP is characterized by aberrant vessel formation in the retina as a response to multiple risk factors influencing the process of retinal angiogenesis. Insulin-like growth factor I (IGF-1) and vascular endothelial growth factor (VEGF) play an important role in the process of normal retinal vascularization. Insufficient nutrition during the first 4 postnatal weeks results in low serum levels of IGF-1, which is essential for correct retinal vessels formation, ensuring survival of the newly formed endothelial cells...

Endothelial cell senescence and Zn nutritional status influence cardiovascular disease. The influence of Zn appears dichotomous, hence it is imperative to understand the relationship with cellular senescence to improve knowledge about the molecular and cellular basis of the disease. Here we aimed to determine: 1) the impact of chronic exposure to a moderately high dose of Zn on senescence of endothelial cells; 2) the changes in Zn homeostasis during the lifespan of primary cultured endothelial cells; and 3) the susceptibility of proliferating and senescent endothelial cells to cell death after short term exposure to increasing doses of Zn and of the Zn chelator TPEN...

The corpus luteum (CL) is an ovarian structure which is critical for the maintenance of reproductive cyclicity and pregnancy support. Diet and/or diet components may affect some luteal functions. FSH is widely used to induce multiple follicle development and superovulation. We hypothesized that FSH would affect luteal function in ewes fed different nutritional planes. Therefore, the aim of this study was to determine if FSH-treatment affects (1) ovulation rate; (2) CL weight; (3) cell proliferation; (4) vascularity; (5) expression of endothelial nitric oxide (eNOS) and soluble guanylate cyclase (sGC) proteins; and (6) luteal and serum progesterone (P4) concentration in control (C), overfed (O), and underfed (U) ewes at the early- and mid-luteal phases...

Endoplasmic reticulum (ER) stress has been implicated in vascular endothelial dysfunction of obesity, diabetes, and hypertension. MicroRNAs play an important role in regulating ER stress. Here we show that microRNA-204 (miR-204) promotes vascular ER stress and endothelial dysfunction by targeting the Sirtuin1 (Sirt1) lysine deacetylase. Pharmacologic ER stress induced by tunicamycin upregulates miR-204 and downregulates Sirt1 in the vascular wall/endothelium in vivo and in endothelial cells in vitro. Inhibition of miR-204 protects against tunicamycin-induced vascular/endothelial ER stress, associated impairment of endothelium-dependent vasorelaxation, and preserves endothelial Sirt1...

Three-dimensional (3D) bioprinting is a promising technology for manufacturing cell-laden tissue-engineered constructs. Larger tissue substitutes, however, require a vascularized network to ensure nutrition supply. Therefore, tailored bioinks combining 3D printability and cell-induced vascularization are needed. We hypothesize that tailored hydrogel blends made of agarose-type I collagen and agarose-fibrinogen are 3D printable and will allow the formation of capillary-like structures by human umbilical vein endothelial cells and human dermal fibroblasts...
