TAC1, a Candida albicans transcription factor situated near the mating-type locus on chromosome 5, is necessary for the upregulation of the ABC-transporter genes CDR1 and CDR2, which mediate azole resistance. We showed previously the existence of both wild-type and hyperactive TAC1 alleles. Wild-type alleles mediate upregulation of CDR1 and CDR2 upon exposure to inducers such as fluphenazine, w...

using microsatellite molecular markers is important particularly due to their high accuracy in studying the genome of the fruit trees. in this study, genetic diversity and relations of 68 almond cultivars and genotypes using microsatellite marker (ssr) were studied. genomic dna extracted from young leaf tissues and pcr reactions were performed using 22 selected primers (among 100 primers) of mi...

Background: HLA compatibility between transplant donor and recipient is one of the major determinants of transplant outcome. Objective: To determine HLA class I by PCR- Sequence-Specific Oligonucleotide Probe (PCR-SSOP) in cord blood donors. Methods: Genomic DNA of 142 cord blood samples registered at the Cord Blood Bank of Iran at Hematology, Oncology, and Bone Marrow Transplantation Researc...

Dear Editor Analysis of the phenylalanine hydroxylase (PAH McKusick 261600) gene in different populations has revealed more than 320 different mutations associated with phenylketonuria (PKU). One of these mutations, IVS10nt546, results in severe PAH deficiency due to defective mRNA splicing. It accounts for about 40 percent of all mutant alleles in Turkish and between 10 to 20 percent of all mu...

Background:It has been hypothesized that genetic factors other than histocompatibility disparity may play a role in predisposition to developing Chronic Myelogenous Leukemia (CML). In this regard, Th1 and Th2 cytokines and their gene polymorphism seems to be important. Overall expression and secretion of cytokines is dependent, at least in part, on genetic polymorphism (nucleotide variations) w...

Bovine leukocyte antigen (BoLA) DRB3 is a highly polymorphic gene in major histocompatibility complex(MHC) class II that plays a central role in immune responses and production factors. As of yet, molecular andevolutionary characteristics of BoLA-DRB3.2* have not been as fully understood as human and mouse.Therefore, we attempted to analyze variability and phylogeny of BoLA-DRB3.2* and illustra...

Introduction: The natural ecosystems of northern Mato Grosso, Brazil, are in process fragmentation, mainly due to population growth and the expansion agriculture. This endangers palm Euterpe precatoria (locally known as açaí), used for construction, hearts, juices ice cream. Objective: To evaluate local diversity genetic structure native populations E. precatoria. Methods: We collected leaves f...
