New Jersey-Based Biotech Start-Up Nexomics Biosciences Gets Off the Ground

... software and an early stage antibiotic screening methodology. In addition, the agreement gives Nexomics rights to use and further develop a novel ribosomal RNA methyltransferase assay for identifying specific binding and inhibition of R1mA proteins from bacterial species. The invention has applications ...

Converting adult somatic cells to pluripotent stem cells using a single virus

... is comprised of a single multicistronic mRNA encoding the four transcription factors using a combination of 2A peptide technology and an internal ribosomal entry site (IRES). With the STEMCCA vector, the researchers were able to generate iPS cells more efficiently -- 10 times higher than previously ...

Biologist finds plant polymerases IV and V are really variants of Polymerase II

... Cell , the Pikaard lab announced a breakthrough in understanding the phenomenon of nucleolar dominance, the silencing of an entire parental set of ribosomal RNA genes in a hybrid plant or animal. That study is one of the first to demonstrate how siRNAs can play a role in controlling the dosage of vital ...

Researchers identify new leprosy bacterium

... infections in cancer patients. Han developed in 2002 a way to identify unusual bacteria by analyzing small but significant differences in the 16S ribosomal RNA gene. "This is like a fingerprint analysis to solve crimes," Han said. He has discovered and named several new bacterial species that cause ...

Gene expression differences between Europeans and Africans affect response to drugs, infections

... Others were unanticipated, including significant differences in expression levels among genes involved in fundamental cellular processes such as ribosomal biogenesis, transfer RNA processing, and Notch-signaling--part of a complex system of communication that governs basic cellular activities and ...

Emory researchers identify signaling protein for multiple myeloma

... We wanted to know which protein factors in cells are activated by FGFR3 and then transform normal cells to highly malignant cells. We identified ribosomal S6 kinase 2 (RSK2), which is a protein factor that mediates signaling in cells as critical in downstream signaling of FGFR3 in myeloma cells. ...

Human Skin Harbors Many More Types of Bacteria

... a subunit of genetic material called 16S ribosomal DNA from the samples. "It is kind of a common ... is that there is a large database of 16S ribosomal DNA available to scientists. The ambitious ... bacteria. After sequencing those regions, the 16S ribosomal DNA (rDNA) in each colony, she consulted 16S rDNA ...

New Ribosome Finding Could Lead to Antiviral Therapies

... therapies in the near future. “One such finger, located in a ribosomal protein called L3, acts as a switch to help the ribosome coordinate all of ... and these tend to have long tentacle-like structures that extend deep into ribosomal cores.” According to Dinman and Meskauskas’ paper, previous studies ...

Yale Scientist Received Medical Science Prize From Keio University

... of his outstanding achievement on the structural basis of the large ribosomal subunit function and drug development, and a commemorative symposium. ... in 2000 produced the first X-ray crystallographic imaging of the large ribosomal subunit. From this work, he and his collaborators have gone on to identify ...

Tigecycline – New Generation Tetracycline With Broad Spectrum Antibacterial Activit

... Tigecycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. Tigecycline blocks entry of amino-acyl tRNA molecules into the A ... Tetracycline drug resistance in bacteria occurred due to mechanisms of ribosomal protection and active drug efflux. But, the new generation tetracycline - ...

Drug Strategy Makes Cancer Genes Get Lost in Translation

... "untranslated regions" at their so-called 5' end, the researchers explained. The lengthy region of weak mRNAs serves as an obstacle for the ribosomal machinery that does the translating, making it a challenge to determine where to begin, he added. In contrast, strong mRNAs have only short 5' ...

Understanding the RNA binding protein and its functions inside the cell

... is derived from the DNA and programs the cells to make proteins. There are many types of RNA in the cells of mammals, such as transfer RNA (tRNA), ribosomal RNA rRNA), and messenger RNA (mRNA). They all have their respective functions to carry on within the cell. RNA-binding proteins are rightly ...

Genes to Extend Longevity Discovered

... The results also show that Hst2 is responsible for Sir2-independent lifespan extension by calorie restriction, and that it does so by suppressing ribosomal DNA recombination, which is the same mechanism by which Sir2 functions. Sinclair's research group have earlier reported in the journal Nature ...
