Project description:Gene expression in the neonatal uterus and vagina from transformation related protein 63 (Trp63) conditional heterozygous and null mice was analyzed in order to identify upstream and downstream of Trp63 in the developing vagina. Differential gene expression between vaginal (Trp63 positive) and uterine (Trp63 negative) tissues should reflect both the upstream and downstream of Trp63 expression, whereas the comparison between conditional knockout and heterozygous vaginae should identify what is downstream of Trp63. Thus, the three-way comparison should identify what is upstream of Trp63. Total RNA was extracted from the Trp63 conditional heterozygous (Trp63 flox/wt ; Pax2-cre) uteri and vaginae, and Trp63 conditional knockout (Trp63 flox/floxt ; Pax2-cre) vaginae. Total 12 samples (3 different genotype/tissue groups x 4 independent samples each).
Project description:Bacterial vaginosis (BV) is the most common cause of vaginal discharge among women worldwide. BV is characterized by an imbalance in the vaginal microbiota with depletion of protective Lactobacillus species and overgrowth of facultative and strictly anaerobic bacteria. Although the development of a polymicrobial biofilm on the vaginal epithelium is a hallmark of BV, interactions between key BV-associated bacteria (BVAB) [i.e. Gardnerella vaginalis, Fannyhessea vaginae, and Prevotella bivia] present in the biofilm are still not completely understood. In this study, we aimed to analyse the transcriptome of single and triple-species biofilms growing in the rich medium, New York City III (NYCIII). A previous analysis of triple-species biofilms composition by qPCR showed that the biofilms were mainly composed of G. vaginalis, followed by F. vaginae and P. bivia. The transcriptomic analysis revealed a total of 431 (34 upregulated and 397 downregulated), 126 (36 upregulated and 90 downregulated), and 39 (31 upregulated and 8 downregulated) differentially expressed genes for G. vaginalis, F. vaginae, and P. bivia, respectively. Gene ontology only detected enrichment for the downregulated genes of G. vaginalis and 47 GO terms were associated with molecular functions, cellular components and biological processes, mainly metabolism. Hence, this work showed the adaptation of 3 BVAB when growing in a triple-species biofilm, with several genes being differentially expressed in all the species growing in a polymicrobial biofilm.
