Mathers Foundation\u003C\/a\u003E have awarded grants of $1 million and $300,000, respectively, to boost the research of Francesca Storici, professor in the School of Biological Sciences and principal investigator for the projects.

Their studies of yeast DNA suggest that rNMPs aren\u0026rsquo;t just random \u0026ldquo;noise,\u0026rdquo; as had been previously alleged, but rather offer a code \u0026ndash; Storici and her colleagues call it \u0026ldquo;cryptic language,\u0026rdquo; capable of regulating DNA functions.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe grants will help researchers begin to translate that cryptic language.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u0026ldquo;These ribonucleotides may represent novel biomarkers for human diseases such as cancer and other degenerative disorders,\u0026rdquo; Storici said.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EMistaken Replication\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFor an organism to grow, its cells must divide.

Using ribose-seq, they discovered hot spots and patterns where rNMP insertions accumulate \u0026ndash; accumulations that were assumed to be random noise.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBased on their recent findings, the researchers hypothesize that some rNMPs form specific motifs, or cryptic words, in human DNA, comprising previously hidden signals for specific metabolic functions of DNA, such as gene expression and replication.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;We don\u0026rsquo;t think this cryptic language of ribonucleotides is random. So, our goal is to decode the cryptic language,\u0026rdquo; Storici said. \u0026ldquo;Currently, we know nothing about that. There may be a particular sequence, or patterns of regularity that we can identify.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EUsing ribose-seq to map rNMPs in DNA, via next-generation sequencing, and a computational toolkit they developed called Ribose-Map, the Storici team will build libraries of rNMP sites from a number of human cell types.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThrough bioinformatic analyses and computational methods, they intend to identify and decipher the cryptic words of rNMP incorporation, \u0026ldquo;setting the stage to discover rNMPs\u0026rsquo; role,\u0026rdquo; Storici said.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe foundations are both supporting the same scope of work, but at different scales, and the researchers will work with different human cell lines for each grant.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe Mathers Foundation will cover work with the Storici lab only.

Mathers Foundation is to advance knowledge in the life sciences by sponsoring scientific research that will benefit humankind. Basic scientific research, with potential translational application, is central to this goal. Since commencing grantmaking activities in 1982, the Mathers Foundation has granted more than $350 million. For many years, the foundation has enjoyed special recognition in the research community in supporting basic scientific research, realizing that true transformative breakthroughs usually occur after a thorough understanding of the fundamental mechanisms underlying natural phenomena. More recently, and with the advent of newer investigative methodologies, technology, and tools, the foundation now embraces innovative translational research proposals.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EAbout the W.M.\u0026nbsp;Keck Foundation\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe W.M.\u0026nbsp;Keck Foundation was established in 1954 in Los Angeles by William Myron Keck, founder of The Superior Oil Company.\u0026nbsp;One of the nation\u0026rsquo;s largest philanthropic organizations, the W.M.\u0026nbsp;Keck Foundation supports outstanding science, engineering, and medical research.\u0026nbsp;The foundation also supports undergraduate education and maintains a program within Southern California to support arts and culture, education, health, and community service projects.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EAbout the \u003C\/strong\u003E\u003Cstrong\u003EGeorgia Institute of Technology\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe Georgia Institute of Technology, or Georgia Tech, is a top 10 public research university developing leaders who advance technology and improve the human condition.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe Institute offers business, computing, design, engineering, liberal arts, and sciences degrees.
