We report the heavy (H) and light (L) chain variable (V) region sequences of cDNAs encoding the Ig receptor of two cases of CD5+ IgG-bearing CLL P87 and P103. In both CLL cases the H chain was encoded by members of the VH3 gene family. The L chain expressed by P87 belonged to the V lambda IV subgroup, whereas P103 used a member of the V kappa III subgroup. The VH3.P87 gene differed by only thre...

Immunoglobulin heavy chains of myeloma proteins from dogs and cata have been subjected to automated sequence analysis. When the results were compared with human heavy-chain sequences, all the dog and cat proteins could be unequivocally assigned to the V(H)III subgroup. This pattern contrasts with that in human proteins in which only 25% of all heavy chains sequenced belong to this subgroup. The...

Abstract_ Introduction: Viola plant has been used traditionally for the treatment of neurological disorders. We aimed at determining whether pretreatment with Viola spathulata extract can alleviate the severity of ischemic-reperfusion damages and it can exert its protective effects through the regulation of a sodium/calcium exchanger (NCX3) gene expression in a rat brain. Methods: Male Wistar r...

BACKGROUND The aim of the study was to determine the effect of gene polymorphisms Arg389Gly ADRβ1 gene and T393C gene GNAS1 on the level of heart rate (HR), systolic and diastolic blood pressure (SBP and DBP) in hypertensive patients according to body mass index (BMI). PATIENTS AND METHODS The study involved 166 patients with hypertension and 90 healthy individuals. Patients of the main group...

Background: In order to characterize human antibodies with specificity for mite allergens at the molecular level, a scFv phage display library was constructed using peripheral blood mononuclear lymphocytes from an asthma patient allergic to mite as Ig gene sources. Methods: Immunoglobulin VH and V gene fragments were obtained by polymerase chain reaction, and randomly combined in pCANTAB-5E vec...

The amino acid sequence of the variable region of a carbohydrate-containing amyloid-fibril protein MOL of immunoglobulin-light-chain type (AL) was elucidated. The sequence determination involved cleaving the protein with CNBr, BNPS-skatole, thermolysin and trypsin. The sequenced protein consisted of about 130 amino acid residues; however, gel-filtration and N-terminal analysis studies revealed ...

In a previous report we presented evidence which indicated that antibody diversity is generated in large part by somatic processes [I] . That evidence was based on DNA-RNA hybridization studies with a purified mouse a-chain mRNA. The present report deals with similar studies using a preparation of mRNA coding for a mouse heavy chain. The results confirm and extend our previous finding, namely t...

The rapid increase of the number of sequenced genomes asks for the functional annotation of the encoded enzymes. We used a combined computational-structural approach to determine the function of the TrpB2 subgroup of the tryptophan synthase β chain/β chain-like TrpB1-TrpB2 family (IPR023026). The results showed that TrpB2 enzymes are O-phospho-l-serine dependent tryptophan synthases, whereas Tr...

The action of a reductive algebraic group G on G/P−, where P− is a parabolic subgroup, differentiates to a representation of the Lie algebra g of G by vector fields on U+, the unipotent radical of a parabolic opposite to P−. We show that both the regular functions on U+ and the polynomial vector fields on U+ form g-modules that are dual to parabolically induced modules, construct an explicit co...
