The PIWI protein regulates gene expression at the epigenetic and post-transcriptional level with a variety of endogenous small non-coding RNAs. In poultry, the biological function of the PIWI protein and PIWI binding to small RNAs had not been determined. The present study cloned and analyzed the sequences of the PIWIL1 protein. We also characterized PIWIL1(More)
Macrophage apoptosis is a host innate defense mechanism against tuberculosis (TB). In this study, we found that percentage of apoptotic cells in peripheral blood monocytes from patients with active TB was lower than that from healthy controls (p<0.001). To understand whether microRNAs can modulate apoptosis of monocytes, we investigated differentially(More)
Piwi gene involves in the germline stem cells self-renewal, transposon silencing and post-transcriptional gene regulation in the majority of organisms; however, the biological function of Piwi gene in poultry remains unclear. Here we cloned the Piwi-like 1 (Piwil1) gene and characterized its expression in the Langshan chickens during the development. The(More)
