α-Synuclein (aSyn) aggregation, mitochondrial dysfunction and oxidative damage has been shown to be related to the death of dopaminergic neurons in Parkinson's disease (PD). Prolyl oligopeptidase (PREP) is proposed to increase aSyn aggregation, and PREP inhibition has been shown to inhibit the aggregation process in vitro and in vivo. In ...

Anchorage-independent survival is one of key features for malignant tumor cells. Whether specific gene alterations contributed by anchorage-independency would further affect metastatic phenotypes of melanoma cells was unclear. We adapted suspension culture of melanoma cells to establish anchorage-independency. The suspended melanoma cells lost their invasive abilities in vitro. Specific loss ...

During a heart attack, the heart's oxygen supply is cut off, and cardiomyocytes perish. Unfortunately, once these tissues are lost, they cannot be replaced and results in cardiovascular disease-the leading cause of deaths worldwide. Advancements in medical research have been targeted to understand and combat the death of these cardiomyocytes. ...

Loss of the endosulfatase HSulf-1 is common in ovarian cancer, upregulates heparin binding growth factor signaling and potentiates tumorigenesis and angiogenesis. However, metabolic differences between isogenic cells with and without HSulf-1 have not been characterized upon HSulf-1 suppression in vitro. Since growth factor signaling is closely tied to metabolic alterations, ...

The immunohistochemical features of fetal haemoglobin cells and their distribution patterns in solid tumours, such as colorectal cancer and blastomas, suggest that fetal haemopoiesis may take place in these tumour tissues. These locally highly concentrated fetal haemoglobin (HbF) cells may promote tumour growth by providing a more efficient oxygen supply. ...

PURPOSE: The bladder wall comprises a complex array of cells, including urothelium, smooth muscle, nerves and interstitial cells. Interstitial cells have several subtypes based on site, morphology and differential expression of markers such as anti-vimentin and anti-KIT. We examined whether a subpopulation of interstitial cells immunopositive for PDGFRα exists in ...

Previous studies using morphine-treated dams reported a role for the rostral lateral periaqueductal gray (rlPAG) in the behavioral switching between nursing and insect hunting, likely to depend on an enhanced seeking response to the presence of an appetitive rewarding cue (i.e., the roach). To elucidate the neural mechanisms mediating such ...

BACKGROUND In patients diagnosed with deep infiltrating endometriosis (DIE), foci of endometriosis are detected in mesorectal lymph nodes (LNs) after segmental bowel resection and in pelvic sentinel LNs. Lymph vessels (LVs) seem to be the possible routes for the dissemination of endometriotic cells from DIE-lesions to LN. Therefore, we conducted ...

Langerhans cells are identified by the expression of langerin. We detected this molecule in cutaneous and mucosal lesions in paracoccidioidomycosis, an important infection in Latin America. Langerin+ cells were scarcely distributed, with short dendrites in epidermis and epithelium and were frequent in the dermis and corium, in the inflammatory infiltrate ...

In double fertilization, the vegetative cell of the male gametophyte (pollen) germinates and forms a pollen tube that brings to the female gametophyte two sperm cells that fertilize the egg and central cell to form the embryo and endosperm, respectively. The 5-methylcytosine DNA glycosylase DEMETER (DME), expressed in the central ...

Scientific progress stimulates the evolution of models used to understand and conceptualize biological behaviors. The widely accepted cell wall model of pollen tube growth explains stochastic growth of the apical pectin wall, but fails to explain the mechanism driving oscillations in growth and cell signaling. Recent advances led to the ...

Microgametogenesis in angiosperms results in two structurally and functionally different cells, one generative cell, which subsequently forms the sperm cells, and the vegetative cell. We analysed the chromatin properties of both types of nuclei after first and second pollen mitosis in rye (Secale cereale). The condensed chromatin of generative nuclei ...

Bladder tissue has been regenerated in humans with neurogenic bladder using an implant produced from autologous urothelial (UC) and smooth muscle cells (SMC) expanded from bladder biopsies seeded onto a biodegradable synthetic scaffold. As the majority of bladder cancers are urothelial carcinomas (aka, transitional cell carcinoma), this 2-cell type autologous ...

BACKGROUND AND PURPOSE: The pathogenesis of chronic rhinosinusitis with nasal polyposis is unknown. Chronic inflammation along with local tissue hypoxia may effect polyp's growth. Activation of Cycloxygenases may also be involved. COX-2 up-regulates in response to different stimuli including hypoxia. Its activation is associated with enhanced cell proliferation. Histologically, besides ...

Allergen-specific IgE production is a hallmark of allergic asthma/rhinitis/eczema. Theoretically this could be due to a high number of allergen-specific B cells or allergen-specific T cells helping allergen-specific B cells differentiate into IgE-producing plasma cells. Here, we determined whether the number of allergen-specific B cells or T helper (Th) cells ...
