Liquid drop of DNA libraries reveals total genome information
Unlike the tightly controlled replication of DNA in living cells, PCR amplification, a “workhorse” of molecular biology, balances between simplicity and accuracy. Conventional “bulk” PCR often yields inefficient and nonuniform amplification of complex templates in DNA libraries, introducing unwanted biases. Researchers from the Laboratory of biocatalysis, Laboratory of proteolytic enzyme chemistry, Laboratory of bioinformatics approaches in combinatorial chemistry and biology, Laboratory of hormonal regulation proteins IBCh RAS together with their Russian and foreign colleagues showed that amplification of single DNA molecules encapsulated in a myriad of emulsion droplets (emulsion PCR, ePCR) allows the mitigation of this problem. The results of this study are published in PNAS. Learn more
- Conformational changes in the receptor tyrosine kinase IRR during activation were determined
Researchers of the Laboratory of Receptor Cell Biology IBCh RAS together with colleagues from the IPCE RAS and IC RAS carried out a study of the IRR structure by atomic force microscopy and small-angle X-ray scattering. The conformations of the receptor in the active and inactive states have been determined; on the basis of the obtained data, an activation mechanism has been proposed.
- The role of natural mutations of the human protein SLURP-1 in the pathogenesis of Mal de Meleda skin disease has been determined
Mal de Meleda (MDM) is recessively inherited palmoplantar keratoderma associated with mutations in a gene encoding SLURP-1 protein. SLURP-1 is a paracrine regulator of keratinocyte homeostasis interacting with the α7 type nicotinic acetylcholine receptor (α7-nAChR). This receptor participates in control of growth, terminal differentiation, apoptosis and cornification of keratinocytes. Dysregulation of the α7-nAChR function due to SLURP-1 deficiency or point mutations of this protein may underlie MDM pathogenesis.
- Genomic DNA i-motifs as fast sensors responsive to near-physiological pH microchanges
Researchers from Federal Research and Clinical Center of Physical-Chemical medicine and Institute of Bioorganic Chemistry RAS, in collaboration with Skolkovo University of Science and Technology and D.Mendeleev University of Chemical Technology of Russia developed simple and robust sensors for detecting microchanges in intracellular pH.
