In intestinal epithelia, cholera and related toxins elicit a cAMP-dependent chloride secretory response fundamental to the pathogenesis of toxigenic diarrhea. We recently proposed that specificity of cholera toxin (CT) action in model intestinal epithelia may depend on the toxin's cell surface receptor ganglioside G(M1). Binding G(M1) enabled the toxin to elicit a response, but forcing the toxi...
The globular domain of type IV collagen from bovine glomerular basement membrane was solubilized by collagenase digestion. Components of this domain include several monomer-size and structurally related dimer-size polypeptides. The monomer-size polypeptides were resolved into three fractions (M1, M2, and M3) with slightly different mobilities upon sodium dodecyl sulfate-polyacrylamide gel elect...
Cyclin D1 is an important cell cycle regulator but in cancer its overexpression also increases cellular migration mediated by p27 stabilization and RhoA inhibition. Recently, a common polymorphism at the exon 4-intron 4 boundary of the human cyclin D1 gene within a splice donor region was associated with an altered risk of developing cancer. Altered RNA splicing caused by this polymorphism give...
Ancient and modern 183 varieties of winter 23 spring types development bread wheat (Triticum aestivum L.) selected Ukrainian state institutions private companies are characterized by alleles Ppd-D1, Ppd-B1, Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. ...
Background. The CCND1 gene generates two mRNAs (cyclin D1a and D1b) through an alternative splicing at the site of a common A/G polymorphism. Cyclin D1a and b proteins differ in their C-terminus, a region involved in protein degradation and sub-cellular localization. Recent data have suggested that cyclin D1b could be a nuclear oncogene. The presence of cyclin D1b mRNA and protein has been stud...
INTRODUCTION The birth of most mammals features a dramatic increase in oxygen while placenta-derived hormones such as β-estradiol and progesterone plummet. In experimental newborn animals, transiently elevated oxygen concentrations cause death of neurons, astrocytes, and oligodendrocyte precursors. High oxygen has been associated with cerebral palsy in human preterm infants while progesterone i...
The photobiology of two reef corals and the distribution of associated symbiont types were investigated over a depth gradient of 0-60 m at Scott Reef, Western Australia. Pachyseris speciosa hosted mainly the same Symbiodinium C type similar to C3 irrespective of sampling depth. By contrast, Seriatopora hystrix hosted predominantly Symbiodinium type D1a or D1a-like at shallow depths while those ...
Mantle cell lymphoma (MCL) has a rather poor prognosis and currently no truly effective therapy. Gene translocation-mediated constitutive expression of Cyclin D1 seems to play the key role in the pathogenesis of MCL. Here we report that whereas three out of four MCL cell lines expressed the recently identified, highly oncogenic Cyclin D1b isoform, in addition to the canonical Cyclin D1a , eight...
