The diffuse-type of gastric cancer is associated with epithelial to mesenchymal transition. Loss of E-cadherin expression is the hallmark of this process and is largely due to the upregulation of the transcription factors ...

The competing endogenous RNA hypothesis has gained increasing attention as a potential global regulatory mechanism of microRNAs (miRNAs), and as a powerful tool to predict the function of many noncoding RNAs, including ...

The HIV-1 genome is a positive sense RNA (gRNA), which is found as a dimer in the viral particle. During the late stages, the gRNA acts as an mRNA encoding Gag and Gag-Pol, and is also the genome packaged into the new ...

Two hundred and eighteen Bacillus thuringiensis isolates from Brazil were characterized by the presence of crystal protein genes by PCR with primers specific to different cry and cyt genes. Among these isolates, 95 were ...

Technologies involving the use of double-stranded RNA (dsRNA) to elicit RNA interference (RNAi) in pest control have emerged as an alternative to traditional pesticides. RNAi can mediate natural cell protection being a ...

The circadian clock is an important endogenous timekeeper, helping plants to prepare for the periodic changes of light and darkness in their environment. The clockwork of this molecular timer is made up of clock proteins ...
