Histopathological and aquaporin7 mRNA expression analyzes in the skeletal and cardiac muscles of obese db/db mice.

The aim of this study is to examine 1) muscle fiber type composition, 2) myofiber diameter, and 3) aquaporin (AQP) 7 and AQP 9 mRNA expressions by quantitative PCR in muscles of obese db/db mice. The myofiber type composition of skeletal muscle was not statistically significantly different between db/db mice and control mice; while the average myofiber diameter ratio showed a decrease in db/db mice. The expression of AQP7 but not AQP9 mRNA in the skeletal and cardiac muscles was significantly upregulated in db/db mice.

Introduction: Vaginal cuff dehiscence after hysterectomy is a rare complication and occurs in less than 1% of patients. It can present with serious complications, such as bowel evisceration and peritonitis.

Presentation Of Case: A 51-year-old multigravida Korean woman underwent total laparoscopic hysterectomy for leiomyoma.

[A case of chronic myopathy associated with an antibody to signal recognition particle (SRP) following long-term asymptomatic hypercreatinekinasemia].

A 65-year-old man first visited our hospital due to hypercreatinekinasemia (hyperCKemia) (669 IU/l) 12 years ago at age 53. At that time, he had normal muscle strength without other neurological deficits, electromyography (EMG) was normal, and a muscle biopsy obtained from the biceps brachii was intact in routine histochemical studies. These findings led to a diagnosis of idiopathic hyperCKemia that lasted for over a decade.

Successful delivery after abdominal radical trachelectomy followed by adjuvant chemotherapy for advanced invasive uterine cervical cancer: a case report and literature review.

Uterine cervical cancer is increasingly prevalent among young Japanese women who are eager to preserve their fertility, and abdominal radical trachelectomy (ART) is often performed in patients with early-stage invasive lesions. Herein we present details of a 27-year-old woman with stage IB1 cervical cancer. Although the patient received ART, histopathological findings revealed a parametrial invasion.

Adenosarcoma of the uterine body initially presenting as an interstitial small tumor of the uterus: a case report.

Adenosarcoma of the uterine body is a rare mixed tumor in which a benign epithelial component is mixed with a malignant stromal element. It has been considered that this tumor originates from the endometrium and its most common finding of imaging is a polypoid tumor occupying the uterine cavity. The authors herein present a case of 37-year-old female with a complaint of abnormal vaginal bleeding.

Upregulated Expression of AQP 7 in the Skeletal Muscles of Obese ob/ob Mice.

Aquaporin (AQP) is suggested to be regulated by leptin through the phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin pathway. AQP7 and AQP9 are membrane proteins with water and glycerol channels, the latter of which is essential for triglyceride synthesis. We conjectured that the expression of AQP7 and AQP9 would be altered in the skeletal myofibers in obese leptin deficient ob/ob mice as compared with that of wild mice.

Aquaporin 4 Expression in the mdx Mouse Diaphragm.

Expression of aquaporin (AQP) 4 in the surface membranes of skeletal myofibers is well established; however, its functional significance is still unknown. The alterations of AQP4 expressions in dystrophic muscles at RNA and protein levels have been reported in various dystrophic muscles such as dystrophinopathy, dysferlinopathy, and sarcoglycanopathy. We are interested in the relationship between the severity of dystrophic muscle degeneration and the expression of AQP4.

Immunocytochemical studies of aquaporin 4, Kir4.1, and α1-syntrophin in the astrocyte endfeet of mouse brain capillaries.

One of the most important physiological roles of brain astrocytes is the maintenance of extracellular K(+) concentration by adjusting the K(+) influx and K(+) efflux. The inwardly rectifying K(+) channel Kir4.1 has been identified as an important member of K(+) channels and is highly concentrated in glial endfeet membranes.

Dysbindin, syncoilin, and beta-synemin mRNA levels in dystrophic muscles.

Progressive muscular dystrophies are genetic diseases with various modes of transmission. Duchenne muscular dystrophy (DMD) is caused by the defect of dystrophin, and Fukuyama congenital muscular dystrophy (FCMD) is caused by an abnormal fukutin gene leading to the glycosylation defect of alpha-dystroglycan. Dystrobrevin is one member of the dystrophin glycoprotein complex and its binding partners include dysbindin, syncoilin, and beta-synemin (desmuslin).

Aquaporin 9 expression and its localization in normal skeletal myofiber.

The examination was performed whether aquaporin (AQP) 9 is expressed in normal skeletal muscle at mRNA and protein levels. Gel electrophoresis of the reverse transcription-polymerase chain reaction (RT-PCR) product of total RNA samples of human normal muscles by oligonucleotide primers for human AQP9 showed a band of 221 basepairs, which corresponded to the basepair length between two primers of AQP9. The nucleotide sequence of RT-PCR product coincided with that of human AQP9.

Immunohistochemical detection of dysbindin at the astroglial endfeet around the capillaries of mouse brain.

Dysbindin was first identified by the yeast two hybrid assay as a binding partner of dystrobrevin which is a cytoplasmic member of dystrophin glycoprotein complex. Immunolocalization of dystrobrevin in the astrocyte endfeet and endothelial cells in the rat cerebellum was reported. Therefore, we were interested in the expression and localization of dystrobrevin binding protein dysbindin in the mouse brain capillary wall and its surrounding astroglial endfeet.

Skeletal muscle syntrophin interactors revealed by yeast two-hybrid assay.

Syntrophins are the cytoplasmic peripheral proteins of dystrophin glycoprotein complex, of which five (alpha l, beta 1, beta 2, gamma 1 and gamma 2) isoforms have been identified so far. Respective syntrophin isoforms are encoded by different genes but have similar domain structures. At the sarcolemma of skeletal muscle, the most abundant alpha l-syntrophin was shown to interact at its PDZ domain with many membrane proteins.

Reduced expression of sarcospan in muscles of Fukuyama congenital muscular dystrophy.

Expression profiles of sarcospan in muscles with muscular dystrophies are scarcely reported. To examine this, we studied five Fukuyama congenital muscular dystrophy (FCMD) muscles, five Duchenne muscular dystrophy (DMD) muscles, five disease control and five normal control muscles. Immunoblot showed reactions of sarcospan markedly decreased in FCMD and DMD muscle extracts.

Aquaporin 4 mRNA levels in neuromuscular tissues of wild-type and dystrophin-deficient mice.

Aquaporin (AQP) 4 is a water-specific channel protein and is abundant in central nervous tissues and skeletal muscles. Recently, the AQP4 molecule has been increasingly highlighted in its pathophysiological role of several neurological diseases, such as stroke, muscular dystrophy and neuromyelitis optica. We therefore measured the levels of AQP4 mRNA and glyceraldehyde-3 phosphate dehydrogenase mRNA (an internal control) in muscle and brain tissues of wild-type mice (C57BL10/ScSn) and age-matched dystrophin-deficient mdx mice (C57BL10/ScSn mdx) by real-time quantitative RT-PCR.

Aquaporin 1: examination of its expression and localization in normal human skeletal muscle tissue.

To examine aquaporin 1 (AQP1) expression in skeletal muscle tissue precisely, we performed reverse transcription-polymerase chain reaction (RT-PCR) at RNA level and immunoblot analysis, immunohistochemistry and immunoelectron microscopy at protein level. The RT-PCR study of total RNA from normal human skeletal muscle showed a strong single band of AQP1. At the protein level we used two commercially available antibodies, both of which recognize the cytoplasmic domain of the AQP1 molecule.

[Case of neuro-Behçet disease with homonymous quadrantanopsia due to an inflammatory lesion involving the lateral geniculate body].

We report a rare case of a 57-year-old woman of neuro-Behçet disease with homonymous quadrantanopsia due to an inflammatory lesion involving the lateral geniculate body. She had oral and genital ulcers since 1983, and uveitis since May 1985. She received diagnosis of incomplete Behçet disease and was prescribed cyclophosphamide since June 1985.

Generation of muscle aquaporin 4 overexpressing transgenic mouse: its characterization at RNA and protein levels including freeze-fracture study.

We generated the muscle aquaporin 4 (AQP4) overexpressing transgenic mice in order to investigate the skeletal muscle pathology at RNA and protein levels. At RNA level, the AQP4 mRNA expression of soleus, EDL and cardiac muscles in Tg mice was statistically significantly higher than that in wild mice by the real-time reverse transcription polymerase chain reaction method. At protein level examinations, we used the immunoblot, immunohistochemistry and freeze-fracture electron microscopy.
