ABSTRACT
Epithelial-mesenchymal transition (EMT) is a complex biological program between physiology and pathology. Here, amniotic epithelial cells (AEC) were used as in vitro model of transiently inducible EMT in order to evaluate the transcriptional insights underlying this process. Therefore, RNA-seq was used to identify the differentially expressed genes and enrichment analyses were carried out to assess the intracellular pathways involved. As a result, molecules exclusively expressed in AEC that experienced EMT (GSTA1-1 and GSTM3) or when this process is inhibited (KLHL14 and KCNE3) were identified. Lastly, the network theory was used to obtain a computational model able to recognize putative controller genes involved in the induction and in the prevention of EMT. The results suggested an opposite role of lysophosphatidic acid (LPA) synthesis and degradation enzymes in the regulation of EMT process. In conclusion, these molecules may represent novel EMT regulators and also targets for developing new therapeutic strategies.

Mycoplasma mycoides subsp. mycoides is the etiological agent of contagious bovine pleuropneumonia (CBPP). While several findings on CBPP prevalence in Nigeria were documented, no data were reported about the genomic characterization of Nigerian M. mycoides subsp. mycoides strains. Here, we present the draft genome sequences of two novel M. mycoides subsp. mycoides strains isolated in Nigeria.
