Defects in promoters of the nonexpressed DQA2, DQB2, and DOB genes from the class II major histo-compatibility complex were mapped by placing Z and X boxes of these silent genes into a synthetic DRA promoter. These conserved upstream sequences confer B-cell-specific and gamma-interferon-inducible expression to the DRA gene. Since DRA promoters containing the X box from the DQA2 gene and Z boxes...

Abstract Calmodulin-binding transcription activator 1 (CAMTA1) is a factor located on chromosome 1p, and we have recently reported that CAMTA1 expression reduced neurosphere formation tumor growth in nude mice, suggesting can function as suppressor experimental glioma. In the present study, investigated molecular network of CAMTA-1 glioma cells. We established cell lines with doxycycline-induci...

background clindamycin is a frequently used antimicrobial therapeutic medicine used for the treatment of skin and soft tissue infections caused by staphylococcus aureus strains. resistance to this antibiotic is either constitutive or inducible. constitutive resistance to clindamycin could be detected by standard susceptibility testing methods. inducible clindamycin resistance could not be detec...

In order to elucidate transcriptional and metabolic networks associated with lysine (Lys) metabolism, we utilized developing Arabidopsis (Arabidopsis thaliana) seeds as a system in which Lys synthesis could be stimulated developmentally without application of chemicals and coupled this to a T-DNA insertion knockout mutation impaired in Lys catabolism. This seed-specific metabolic perturbation s...

Abstract Background COVID-19 affected the epidemiology of many respiratory pathogens including GAS. Assessing genetic heterogeneity (emm type, antimicrobial resistance, virulence factors) can inform treatment recommendations and targets for potential GAS vaccines. We assessed clinical antibiotic susceptibility performed whole genome sequencing (WGS) among pediatric pharyngeal isolates from 2020...
