Background: Lipophosphoglycan 3 (LPG3) is required for the LPG assembly, a well known virulent molecule. In this study, the LPG3 gene of the lizard and mammalian Leishmania species were cloned and sequenced. A three-dimensional structure (3D) for the target sequence was also predicted by comparative (homology) modeling. Materials and Methods: An optimization PCR amplification was performed o...

objective(s): stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including p15ink4b and p16ink4a genes. epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure.   materials and methods: the cd34 + cord blood stem cells were pu...

objective: to investigate the association of c631t single nucleotide polymorphisms in spo11 gene with male infertilityfollowed by an in silico approach. spo11 is a gene involved in meiosis and spermatogenesis process, which in humans, this gene is located on chromosome 20 (20q13.2-13.3) with 13 exons. materials and methods: in a case-control study, 200 blood samples were collected from the ivf ...

background and aims: since the produced recombinant proteins by molecular genetics techniques commonly have some limitations in the application, chimeric protein are introduced. chimeric proteins have found widespread application for the study of protein folding, structure stability, function and immunogenisity. methods: according to the known immunomodulatory effect and structure of hsp70 mole...

background: gossypium thurberi is a wild diploid species that has been used to improve cultivated allotetraploid cotton. g. thurberi belongs to d genome, which is an important wild bio-source for the cotton breeding and genetic research. to a certain degree, chloroplast dna sequence information are a versatile tool for species identification and phylogenetic implications in plants. different ch...
