Selenium concentration in the brain tissue is far less variable than those in peripherals, such as the liver and kidneys, in rodents, when fed a selenium-deficient diet. This fact implies the importance of this element for maintaining the integrity of

The distribution of selenate and selenite selenium in C57L/J mice during the progression of BW7756 murine hepatoma was investigated using intra-ocular injection with the oxyanions labeled with 75Se radioisotope. Comparison is made with the normal distribution of selenium studied by

Epigenetic silencing mechanisms are essential for regulating germ cell apoptosis in response to different stimuli during complicated spermatogenesis. Herein, we report the potential signaling events related to up-regulation of metastasis associated protein 1 (Mta1), a master chromatin modifier, during mono-(2-ethylhexyl)

In this report, selenious acid (H2SeO3) has been exploited to study the decolorization of a cationic dye, dimethylmethylene blue (DMMB) with UV-light. Micelles have effectively been employed as organized media to promote the rate of decolorization of the dye molecules.

An attractive cell source for cartilage tissue engineering, human adipose-derived stem cells (hASCs) can be easily expanded and signaled to differentiate into chondrocytes. This study explores the influence of growth factor distribution and release kinetics on cartilage formation within 3D

Perivascular mesenchymal precursor cells (i.e., pericytes) reside in skeletal muscle where they contribute to myofiber regeneration; however, the existence of similar microvessel-associated regenerative precursor cells in cardiac muscle has not yet been documented. We tested whether microvascular pericytes within human

A non-invasive method to characterize human mesenchymal stromal cells during adipogenic differentiation was developed for the first time. Seven fatty acid methyl esters (FAMEs), including methyl laurate, methyl myristate, methyl palmitate, methyl linoleate, methyl oleate, methyl elaidate and methyl stearate

The aim of this study was to test the possible involvement, relevance and significance of dentin matrix protein 1 (DMP1) in chondrocyte redifferentiation and OA. To examine the function of DMP1 in vitro, bone marrow stromal cells (BMSCs) and articular

Tissue-engineered (TE) cartilage constructs tend to develop inhomogeneously, thus, to predict the mechanical performance of the tissue, conventional biomechanical testing, which yields average material properties, is of limited value. Rather, techniques for evaluating regional and depth-dependent properties of TE cartilage

The kidneys are formed during development from two distinct primordial tissues, the metanephric mesenchyme and the ureteric bud. The metanephric mesenchyme develops into the kidney nephron, the minimal functional unit of the kidney. A nephron consists of several segments and

Intervertebral disc (IVD) degeneration is one of the main causes of low back pain. Current surgical treatments are complex and generally do not fully restore spine mobility. Development of injectable extracellular matrix-based hydrogels offers an opportunity for minimally invasive treatment

Supranutritional selenite has anti-cancer therapeutic effects in vivo; however, the detailed mechanisms underlying these effects are not clearly understood. Further studies would broaden our understanding of the anti-cancer effects of this compound and provide a theoretical basis for its clinical

Because of a shortage of fresh corneal tissue for research, it was of interest to investigate the potential of successfully isolating human limbal epithelial cells (hLECs) from organ culture corneal-scleral (OCCS) rims. Superficial segments of corneal limbus were dissected and

A critical first step in the metastatic progression of cutaneous melanoma, invasive growth into the dermal compartment, would ideally be studied in the proper three-dimensional tissue microenvironment. In this study, we compared the growth and behavior of four melanoma cell

Hyposalivation is an intractable side‑effect of radiotherapy for head and neck cancer. It is caused by the irreversible loss of acinar cells and decreased saliva secretion. However, this situation severely compromises the quality of life of affected patients. Currently, there

The signals that regulate activation, a key transition in ovarian follicular development, are still not well understood, especially in nonrodent species. To gain insight into the regulation of this transition in cattle, we combined a microarray approach with an in

As a tissue-specific stem cell for chondrogenesis, synovium-derived stem cells (SDSCs) are a promising cell source for cartilage repair. However, a small biopsy can only provide a limited number of cells. Cell senescence from both in vitro expansion and donor

Our previous studies on selenite cytotoxicity led us to hypothesize that drug resistant tumor cells with high intracellular glutathione will exhibit a high degree of sensitivity to selenite. To examine this we studied the effects of selenite on drug resistant

Sarco/endoplasmic reticulum calcium ATPase (SERCA) enzymes play important roles in several signal transduction pathways that control proliferation, differentiation and apoptosis. Here, we reported that SERCA2 expression was positively correlated with tumor node metastasis (TNM) stages (n=75, P=0.0251) and grades (n=63
