Increased expression of Mg(2+) transport proteins enhances the survival of Salmonella enterica at high temperature.

29 Sep 2009 Mg(2+) homeostasis is important for Salmonella pathogenesis. In Salmonella enterica, the transcription of the mgtA gene, which encodes a Mg(2+) transporter, is regulated by a Mg(2+)-sensing riboswitch [Cromie MJ, Shi Y, Latifi T, Groisman EA (2006) ... Read more...

Comprehensive molecular etiology analysis of nonsyndromic hearing impairment from typical areas in China.

8 Sep 2009 BACKGROUND: Every year, 30,000 babies are born with congenital hearing impairment in China. The molecular etiology of hearing impairment in the Chinese population has not been investigated thoroughly. To provide appropriate genetic testing and ... Read more...

Anomalous electrophoretic migration of newly synthesized ribosomal RNAs and their precursors from cells with DKC1 mutations.

31 Aug 2009 Mutations in the X-linked gene, DKC1, encoding dyskerin, cause dyskeratosis congenita by leading to decreased telomerase activity and causing short telomeres. Dyskerin is also a pseudouridine synthase that modifies nascent ribosomal and other RNAs ... Read more...

Technical information about 'RNA, Ribosomal'

Definition: The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome.
