[Paraneoplastic cerebellar degeneration with bladder cancer confirmed the existence of an anti-neural antibody: a case report].

A 66-year-old man was diagnosed with bladder cancer at our urology department. Three months later, he developed subacute progressive cerebellar limb ataxia and truncal oscillation. Analysis of cerebrospinal fluid showed pleocytosis and increased concentrations of protein, while brain magnetic resonance imaging revealed no abnormalities.

Effect of E-cadherin expression on hormone production in rat anterior pituitary lactotrophs in vitro.

Cadherins are a family of transmembrane glycoproteins that mediate cell-to-cell adhesion. A change in cadherin type in cells, i.e.

Living-cell imaging of transgenic rat anterior pituitary cells in primary culture reveals novel characteristics of folliculo-stellate cells.

Folliculo-stellate (FS) cells in the anterior pituitary gland appear to possess multifunctional properties. Recently, the development of transgenic rats (S100b-green fluorescent protein (GFP) rats) that express GFP specifically in FS cells in the anterior pituitary gland has allowed us to distinguish and observe living FS cells in other kinds of pituitary cells. We used S100b-GFP rats to investigate the topographic affinity of FS cells for other pituitary cells.

Estrogen receptor alpha regulates retinaldehyde dehydrogenase 1 expression in rat anterior pituitary cells.

Retinoic acid (RA) plays a critical role in embryonic development, growth, and reproduction. RA is synthesized from retinoids via oxidation processes, and the oxidation of retinal to RA is catalyzed by the retinaldehyde dehydrogenases (RALDHs). We previously reported that RALDH1 mRNA was expressed in the anterior pituitary glands of adult rats and suppressed by administration of 17beta-estradiol in vivo.
