Homeobox genes encode transcription factors which play important roles in the developmental processes of many multicellular organisms. TGIFLX/Y (TGIFLX and TGIFLY) are members of the homeobox superfamily of genes. Their expressions are specifically detected in the human adult testis but their functions are remained to be investigated. In this investigation we cloned full length of TGIFLY cDNA a...

Data are presented from two-dimensional (2-D) PAGE analysis of Mycobacterium tuberculosis strain Harlingen grown during aerobic and anaerobic culture, according to a modified Wayne dormancy model. M. tuberculosis cultures were grown to the transition point between exponential growth and stationary phase in the presence of oxygen (7 days) and then part of the cultures was shifted to anaerobic co...

background: sequence variations in glycoproteins of influenza virus surface impel us to design new candidate vaccines yearly. ectodomain of influenza m2 protein is a surface and highly conserved protein. m2e in influenza vaccines may eliminate the need for changing vaccine formulation every year. objectives: in this study, a recombinant baculovirus containing m2e and cholera toxin subunit b fus...

conclusions the data indicate that esat6-cfp10 could support the survival of m. tuberculosis in the host through altering the host immune response. it also indicates that the host may gain some level of protection from a second exposure to m. tuberculosis, as evidenced by increased proliferation of nr8383-ec. background mycobacterium tuberculosis is the major pathogen of tuberculosis, which aff...

objective: the aim of this study was to construct a pcdna3.1+ vector containing fmdv type o/irn/1/2007-vp1 gene, protein expression in bhkt7 cells and evaluation of immune response in balb/c mice. materials and methods: fmdv type o/irn/1/2007 was isolated from a cattle in ray in 2007 and serotyped. the purified vp1 gene was sub-cloned into the ptz57r/t vector and pcdna3.1+ expression vector. t...

Background: Enterocin-P of Enterococcus faecium P13 (EntP) is of great interest as a food preservative and medicine due to its non-toxicity and broad antimicrobial spectrum in various pH, as well as its excellent thermal stability. However, recombinant production of EntP is still in laboratory because of low productivity and complex purification process. Objectives: In this study, we aimed to ...

BACKGROUND The DevR response regulator is implicated in both hypoxic adaptation and virulence of Mycobacterium tuberculosis (M. tb). DevR regulon genes are powerfully induced in vivo implicating them in bacterial adaptation to host control strategies. A better understanding of DevR function will illumine the way for new strategies to control and treat tuberculosis. METHODOLOGY/PRINCIPAL FINDI...

objective: helicobacter pylori is a widely distributed gram negative bacterium that infects the human stomach and duodenum. some antibiotic regimens are subjected to cure the infection but the cost of drugs, poor patient compliance and emerging of antibiotic-resistant strains are limiting the usefulness of these antibiotic therapies. therefore, interest in developing a h. pylori vaccine is grow...
