Peste des petits ruminants (PPR) is an acute and highly contagious disease in small ruminants that causes significant economic losses in developing countries. An increasing number of studies have demonstrated that both autophagy and apoptosis are important cellular mechanisms for maintaining homeostasis, and they participate in the host response to pathogens. However, the crosstalk between apoptosis and autophagy in host cells during PPRV infection has not been clarified. In this study, autophagy was induced upon...

Inflammation or dysbacteriosis-derived lipopolysaccharides (LPS) adversely influence the embryonic development of respiratory system. However, the precise pathological mechanisms still remain to be elucidated. In this study, we demonstrated that LPS exposure caused lung maldevelopment in chick embryos, including higher embryo mortality, increased thickness of alveolar gas exchange zone, and accumulation of PAS+ immature pulmonary cells, accompanied with reduced expression of alveolar epithelial cell markers and lamellar body count. Upon LPS exposure, pulmonary cell proliferation was...

The MYC and RAS oncogenes are sufficient for transformation of normal rodent cells. This cooperativity is at least in part based on suppression of RAS-induced cellular senescence by MYC and block of MYC-induced apoptosis by RAS – thereby canceling out two main barriers against tumor development. However, it remains unclear whether MYC and RAS cooperate in this way in human cells, where MYC and RAS are not sufficient for transformation. To address this question, we...
