Carbonic anhydrase (CA) isoenzyme IX is a hypoxia-inducible enzyme, which is expressed in the human and rodent gastrointestinal tract and overexpressed in several different tumors. Functionally, it has probably an effect on proliferation and differentiation of gastrointestinal epithelial cells. It
Retina and retinal pigment epithelium (RPE) belong to the metabolically most active tissues in the human body. Efficient removal of acid load from retina and RPE is a critical function mediated by the choriocapillaris. However, the mechanism by which pH homeostasis is maintained is largely unknown.
OBJECTIVE
Gyrate atrophy of the choroid and retina (GACR) is a rare chorioretinal dystrophy characterized by a deficiency of the enzyme ornithine aminotransferase, inherited in an autosomal recessive pattern.
METHODS
We report a case of a 17-year-old girl with GACR, for whom the level of serum
Both immunohistochemical and biochemical evidence is presented to show for the first time that carbonic anhydrase II (CA II) activity falls in the brain of mice in cuprizone (bis(cyclohexanone)oxalyldihydrazone) induced demyelination well before demyelination develops. This fall began during the
Serum of a patient with paraneoplastic cerebellar degeneration (PCD) and malignant melanoma had a unique reactivity with Purkinje cells that was not observed in serum of patients with PCD and other tumors, or with malignant melanoma without paraneoplastic syndromes. The screening of a human
Paraneoplastic cerebellar degeneration is a neurological syndrome resulting from immune-mediated dysfunction of Purkinje cells and commonly is associated with a tumor. In most cases, well-characterized onconeural antibodies are detected, such as anti-Yo and anti-Ri antibodies. Carbonic
OBJECTIVE
Back pain is a major cause of disability, affecting millions of people worldwide. One cause of axial back pain is degeneration of the nucleus pulposus (NP) of the intervertebral disc. This study was undertaken to investigate associations of NP cells with cell surface-specific proteins that
Carbonic anhydrase inhibitor acetazolamide blocks the hypercalcemic response to parathyroid hormone (PTH) and to dibutyryl 3',5'-cyclic AMP in the nephrectomized-parathyroidectomized rat. In addition, we have reported that acetazolamide, when incorporated in the diet, partially prevents
A recent report of a novel carbonic anhydrase (CDCA1) with Cd as its metal centre in the coastal diatom Thalassiosira weissflogii has led us to search for the occurrence of this Cd enzyme (CDCA) in other marine phytoplankton and in the environment. Using degenerate primers designed from the
Tobacco plants secrete a limited array of proteins (nectarins) into their floral nectar. N-terminal sequencing of the Nectarin II ( NEC2; 35kD) and the Nectarin III ( NEC3; 40kD) proteins revealed that they both share identity with dioscorin, the major soluble protein of yam tubers. These sequences
Trichinellosis is a globally distributed helminthic infection. There is a considerable interest in developing new anti-helminthic drugs affecting all the developmental stages of Trichinella. Acetazolamide (carbonic anhydrase (CA) inhibitor) involves a novel mechanism of action by inhibiting such an
Experimental autoimmune sialoadenitis was induced in PL/J (H-2u) mice by intradermal immunization with human carbonic anhydrase II (CAII) and adjuvant containing monophosphoryl lipid A and trehalose diorynomycolate. Mice immunized with CAII showed a significant increase in the number and size of
The regulation of the acid-base balance in cells is essential for proper cellular homeostasis. Disturbed acid-base balance directly affects cellular physiology, which often results in various pathological conditions. In every living organism, the protein family of carbonic anhydrases regulate a
BACKGROUND
Taste and smell dysfunction has been reported to occur in patients with a variety of clinical problems. We wanted to investigate a specific group of patients in whom taste and smell dysfunction occurred putatively related to a specific biochemical abnormality in a salivary growth factor
