Differentiation of malaria male gametocytes is initiated by recruitment of a chromatin remodeler to male-specific cis-acting elements (RNA-Seq)

Project description:By targeting disruption of SNF2, male gametocytes lost capacity for exflagellation completely, and transcripts of male-specific genes decreased significantly, whereas female gametocytes display normal phenotype. ChIP-seq analysis showed that gSNF2 molecules were divided into two groups according to motif sequences on the genome they were recruited: those recruited to female-specific cis-acting element, TGTRNNYACA, and those recruited to a five base motif, YGTCT, that exists on the upstream of male-specific genes. Studies using a male-specific dynein promoter demonstrated that the five-base motif is a male-specific cis-acting element. ATAC-seq analysis demonstrated that the disruption of gSNF prohibits creation of a nucleosome-free region (NFR) on the promoter of male-specific target genes, and the reduction rates of NFR correlated well with those of target gene expression. These results suggests that global changes of chromatin structure by gSNF2 occur in initial step of male development. The present study also suggested that male-specific gene expression is under the control of a single kind of male-specific cis-acting element thus a single sequence-specific TF. This is a first report genome-wide changes of nucleosome positioning by a remodeling complex play a role in stage conversion of this parasite.

The proteomes of plasmodium falciparum mature male and female gametocytes

Project description:Gametocytes are obligate for the transmission of malaria parasite to mosquito. This study reports the first comprehensive proteomes of accurately separated mature male and female Plasmodium falciparum gametocytes using a transgenic line. the proteomes revealed significant differences that are consistent with the divergent functions of the two sexes. While the male proteome is enriched in proteins associated with flagella and genome replication, the female proteome is more abundant in proteins involved in metabolism, translation and organellar functions.

Expression analysis of Plasmodium falciparum male and female gametocytes

Project description:Investigation of whole genome gene expression level in Plasmodium falciparum male and female mature gametocytes, and detection of any transcriptional differences between male and female gametocytes. The Plasmodium falciparum parasite with green fluorescent protein (GFP) expression under the control of alpha tubulin II promoter facilitated the separation of male and female gametocyte.
