Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself or by forming a template for the production of proteins. RNA and deoxyribonucleic acid (DNA) are nucleic acids. The nucleic acids constitute one of the four major macromolecules essential for all known forms of life. RNA is assembled as a chain of nucleotides. Cellular organisms use messenger RNA (mRNA) to convey genetic information that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.
Gene knockouts are a widely used genetic engineering technique that involves the targeted removal or inactivation of a specific gene within an organism's genome. This can be done through a variety of methods, including homologous recombination, CRISPR-Cas9, and TALENs.
The Stanford University School of Medicine is the medical school of Stanford University and is located in Stanford, California, United States. It traces its roots to the Medical Department of the University of the Pacific, founded in San Francisco in 1858. This medical institution, then called Cooper Medical College, was acquired by Stanford in 1908. The medical school moved to the Stanford campus near Palo Alto, California, in 1959.

The school also operates a biomedical research enterprise and a range of public-service initiatives throughout the state.
Phillip Allen Sharp is an American geneticist and molecular biologist who co-discovered RNA splicing. He shared the 1993 Nobel Prize in Physiology or Medicine with Richard J. Roberts for "the discovery that genes in eukaryotes are not contiguous strings but contain introns, and that the splicing of messenger RNA to delete those introns can occur in different ways, yielding different proteins from the same DNA sequence". He has been selected to receive the 2015 Othmer Gold Medal.
The RNA-induced silencing complex, or RISC, is a multiprotein complex, specifically a ribonucleoprotein, which functions in gene silencing via a variety of pathways at the transcriptional and translational levels. Using single-stranded RNA (ssRNA) fragments, such as microRNA (miRNA), or double-stranded small interfering RNA (siRNA), the complex functions as a key tool in gene regulation. The single strand of RNA acts as a template for RISC to recognize complementary messenger RNA (mRNA) transcript. Once found, one of the proteins in RISC, Argonaute, activates and cleaves the mRNA. This process is called RNA interference (RNAi) and it is found in many eukaryotes; it is a key process in defense against viral infections, as it is triggered by the presence of double-stranded RNA (dsRNA).

Craig Cameron Mello is an American biologist and professor of molecular medicine at the University of Massachusetts Medical School in Worcester, Massachusetts. He was awarded the 2006 Nobel Prize for Physiology or Medicine, along with Andrew Z. Fire, for the discovery of RNA interference. This research was conducted at the Carnegie Institution of Washington and published in 1998. Mello has been a Howard Hughes Medical Institute investigator since 2000.
Carolyn Widney Greider is an American molecular biologist and Nobel laureate. She is a Distinguished Professor of Molecular, Cell, and Developmental Biology at the University of California, Santa Cruz.
RNA silencing or RNA interference refers to a family of gene silencing effects by which gene expression is negatively regulated by non-coding RNAs such as microRNAs. RNA silencing may also be defined as sequence-specific regulation of gene expression triggered by double-stranded RNA (dsRNA). RNA silencing mechanisms are conserved among most eukaryotes. The most common and well-studied example is RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA. Other classes of small RNA have been identified, including piwi-interacting RNA (piRNA) and its subspecies repeat associated small interfering RNA (rasiRNA).
Sir David Charles Baulcombe is a British plant scientist and geneticist. As of October 2024 he was Head of Group, Gene Expression, in the Department of Plant Sciences at the University of Cambridge, and the Edward Penley Abraham Royal Society Research Professor and Regius Professor of Botany Emeritus at Cambridge. He held the Regius botany chair in that department from 2007 to 2020.

The Wiley Prize in Biomedical Sciences is intended to recognize breakthrough research in pure or applied life science research that is distinguished by its excellence, originality and impact on our understanding of biological systems and processes. The award may recognize a specific contribution or series of contributions that demonstrate the nominee's significant leadership in the development of research concepts or their clinical application. Particular emphasis will be placed on research that champions novel approaches and challenges accepted thinking in the biomedical sciences.
RNA interference (RNAi) is a biological process in which RNA molecules are involved in sequence-specific suppression of gene expression by double-stranded RNA, through translational or transcriptional repression. Historically, RNAi was known by other names, including co-suppression, post-transcriptional gene silencing (PTGS), and quelling. The detailed study of each of these seemingly different processes elucidated that the identity of these phenomena were all actually RNAi. Andrew Fire and Craig C. Mello shared the 2006 Nobel Prize in Physiology or Medicine for their work on RNAi in the nematode worm Caenorhabditis elegans, which they published in 1998. Since the discovery of RNAi and its regulatory potentials, it has become evident that RNAi has immense potential in suppression of desired genes. RNAi is now known as precise, efficient, stable and better than antisense therapy for gene suppression. Antisense RNA produced intracellularly by an expression vector may be developed and find utility as novel therapeutic agents.
The Massry Prize was established in 1996, and is administered by the Meira and Shaul G. Massry Foundation. The Prize, of $40,000 and the Massry Lectureship, is bestowed upon scientists who have made substantial recent contributions in the biomedical sciences. Shaul G. Massry, M.D., who established the Massry Foundation, is Professor Emeritus of Medicine and Physiology and Biophysics at the Keck School of Medicine, University of Southern California. He served as Chief of its Division of Nephrology from 1974 to 2000. In 2009 the KECK School of Medicine was asked to administer the Prize, and has done so since that time. Out of 25 prizes bestowed until 2021, fourteen were awarded to future Nobel Prize winners. No Massry Prize was awarded in 2020, 2022 and 2023.
