RNAi-Based Functional Genomics Identifies New Virulence Determinants in Mucormycosis

RNAi-Based Functional Genomics Identifies New Virulence Determinants in Mucormycosis

Mucorales are an emerging group of human pathogens that are responsible for the lethal disease mucormycosis. Unfortunately, functional studies on the genetic factors behind the virulence of these organisms are hampered by their limited genetic tractability, since they are reluctant to classical genetic tools like transposable elements or gene mapping. Here, we describe an RNAi-based functional ...

RNAi Towards Functional Genomics Studies

RNAi for Plant Functional Genomics

A major challenge in the post-genome era of plant biology is to determine the functions of all the genes in the plant genome. A straightforward approach to this problem is to reduce or knock out expression of a gene with the hope of seeing a phenotype that is suggestive of its function. Insertional mutagenesis is a useful tool for this type of study, but it is limited by gene redundancy, lethal...

RNAi for functional genomics in plants.

RNAi refers to several different types of gene silencing mediated by small, dsRNA molecules. Over the course of 20 years, the scientific understanding of RNAi has developed from the initial observation of unexpected expression patterns to a sophisticated understanding of a multi-faceted, evolutionarily conserved network of mechanisms that regulate gene expression in many organisms. It has also ...

Functional genomics identifies drivers of medulloblastoma dissemination.

Medulloblastomas are malignant brain tumors that arise in the cerebellum in children and disseminate via the cerebrospinal fluid to the leptomeningeal spaces of the brain and spinal cord. Challenged by the poor prognosis for patients with metastatic dissemination, pediatric oncologists have developed aggressive treatment protocols, combining surgery, craniospinal radiation, and high-dose chemot...
