Duplicated var2csa genes in a single strain of Plasmodium falciparum are at the same time transcribed, difficult the dogma of mutual Plasmodium duplicate gene expression special var gene transcription
AbstractBackground: Solitary nucleotide polymorphisms are prevalent in duplicated genes, triggering practical preservation, alteration or silencing. The Plasmodium falciparum genes var2csa and Pf332 are duplicated during the haploid genome of your HB3 parasite line. While the molecular functionality of Pf332 stays being elucidated, VAR2CSA is understood for being the key adhesin in placental parasite sequestration. Sequence variations launched on duplication of these genes deliver discriminative opportunities to investigate allele-specific transcription with a bearing in the direction of comprehending gene dosage effect on parasite biology. Success: We display an method combining real-time PCR allelic discrimination and discriminative RNA-FISH to distinguish in between extremely very similar gene copies in P. falciparum parasites. The duplicated var2csa variants are concurrently transcribed, the two on the population level and intriguingly also in specific cells, with nuclear co-localization with the lively genes and corresponding transcripts. This indicates transcriptional functionality of duplicated genes, difficulties the dogma of mutually exclusive var gene transcription and implies mechanisms powering antigenic variation, at the least in regard for the duplicated and really similar var2csa genes. Conclusions: Allelic discrimination assays have usually been utilized to review zygosity in diploid genomes. The assays offered listed below are in its place productively utilized on the identification.
