Continuous treatment with cisplatin induces the oocyte death of primordial follicles without activation.

Chemotherapy directly or indirectly affects organs in a short-term or continuous manner. Endocrine organs are especially sensitive to cancer treatment, leading to concerns among patients regarding their quality of life afterward. Side effects to the ovary include damage to the ovarian reserve, resulting in follicle loss, endocrine hormone deficiency, and infertility.

Intimate Attachment of O157:H7 to Urinary Bladder Epithelium in the Gnotobiotic Piglet Model.

Enterohemorrhagic (EHEC), a pathogenic subset of Shiga toxin-producing (STEC), is an important cause of hemorrhagic colitis and hemolytic-uremic syndrome (HUS), and a rare cause of urinary tract infections (UTIs) with associated HUS. EHEC strains attach intimately to intestinal epithelium with formation of actin pedestals (attaching-effacing (A/E) lesions); however, the mechanism of EHEC attachment to the uroepithelium is unknown. We conducted a retrospective study on archived urinary bladder specimens from gnotobiotic piglets that naturally developed cystitis associated with EHEC O157:H7 infection following oral inoculation and fecal shedding.

Casitas B-cell lymphoma (Cbl) proteins protect mammary epithelial cells from proteotoxicity of active c-Src accumulation.

Casitas B-cell lymphoma (Cbl) family ubiquitin ligases negatively regulate tyrosine kinase-dependent signal transduction by promoting degradation of active kinases. We and others previously reported that loss of Cbl functions caused hyperproliferation in lymphoid and hematopoietic systems. Unexpectedly, Cbl deletion in Cbl-b-null, Cbl-c-null primary mouse mammary epithelial cells (MECs) (Cbl triple-deficiency) induced rapid cell death despite enhanced MAP kinase and AKT activation.

Differentiation of embryonic stem cells into fibroblast-like cells in three-dimensional type I collagen gel cultures.

Fibroblasts are heterogeneous mesenchymal cells that play important roles in the production and maintenance of extracellular matrix. Although their heterogeneity is recognized, progenitor progeny relationships among fibroblasts and the factors that control fibroblast differentiation are poorly defined. The current study was designed to develop a reliable method that would permit in vitro differentiation of fibroblast-like cells from human and murine embryonic stem cells (ESCs).

The endocytic recycling regulator EHD1 is essential for spermatogenesis and male fertility in mice.

Background: The C-terminal Eps15 homology domain-containing protein 1 (EHD1) is ubiquitously expressed and regulates the endocytic trafficking and recycling of membrane components and several transmembrane receptors. To elucidate the function of EHD1 in mammalian development, we generated Ehd1-/- mice using a Cre/loxP system.

Results: Both male and female Ehd1-/- mice survived at sub-Mendelian ratios.

Cultured lung fibroblasts from ovalbumin-challenged "asthmatic" mice differ functionally from normal.

Asthmatic airway remodeling is characterized by goblet cell hyperplasia, angiogenesis, smooth muscle hypertrophy, and subepithelial fibrosis. This study evaluated whether acquired changes in fibroblast phenotype could contribute to this remodeling. Airway and parenchymal fibroblasts from control or chronically ovalbumin (OVA)-sensitized and challenged "asthmatic" mice were assessed for several functions related to repair and remodeling +/- exogenous transforming growth factor (TGF)-beta.

Comparison of long-term perifused pars intermedia of Anolis carolinensis, Rana pipiens and Hyla chrysoscelis: their responses to dopamine.

Pituitary pars nervosa-pars intermedia of Anolis carolinensis, Rana pipiens and Hyla crysoscelis were perifused with synthetic medium 199 for up to 35 h. The pre- and post-perifused tissues were examined by electron microscopy. No neuronal endings were found in Anolis tissue, but both Rana and Hyla had occasional synaptic end bulbs, which remained visible in the post-perifused tissue, although the synaptic vesicles appeared to cluster in the center of the end bulbs.

Fluorescence and electron microscopy probes for cellular and tissue uptake of poly(D,L-lactide-co-glycolide) nanoparticles.

Nanoparticles formulated from poly(D,L-lactide-co-glycolide) (PLGA) and poly(lactide) (PLA) are being extensively investigated for different therapeutic applications such as for sustained drug, vaccine, and gene delivery. For many of these applications, it is necessary to study the intracellular distribution as well as the tissue uptake of nanoparticles to optimize the efficacy of the encapsulated therapeutic agent. Fluorescence and electron microscopic techniques are usually used for the above purposes.
