is a comprehensive online database that provides concise genomic information on all known and predicted human genes. With more than 13 million page visits per year from more than two million unique users worldwide according to Google Analytics, is accessed by professionals in more than 3,000 institutions including academia, research hospitals, patent offices, and leading biotech and pharma companies. was developed, and is continuously enhanced, by ongoing research conducted by the bioinformatics team at the Department of Molecular Genetics at the Weizmann Institute of Science in Israel, with principal investigator Professor Doron Lancet, head of the Crown Human Genome Center, and team leader Marilyn Safran.

The new release includes more than 113,000 gene entries, of which approximately 71,000 genes encode non-coding RNAs. The release debuts ’ novel unified pathways, an enhancement which is designed to assist in resolving redundancies and inconsistencies in gene pathway representation. For this, a judicious clustering algorithm allows joining together, for every gene, the relevant pathways from 11 sources into “super-pathways”, based on gene-sets overlaps. Individual genes now portray the relevant super-pathways and their pathway content, in addition to original source-based lists. This enables more meaningful characterizations of a gene via its pathway affiliation. Another important enhancement is new integrated protein expression images, covering 23 tissues that combine data from both MOPED and also from a new source, PaxDB. Other key enhancements include new functional summaries incorporating expanded information regarding embryonic development-related genes, as well as improved representation of stem cell differentiation, all obtained from ™, the database of embryonic development, stem-cell research and regenerative medicine.

Most researchers utilize a single source of pathways in their gene characterization protocols. ’ super-pathways represent a much more balanced view of the pathway universe,” said Professor Doron Lancet, Ph.D., The Ralph D. and Lois R. Silver Professor of Human Genomics, at the Weizmann Institute of Science.

“We are delighted to see the continued improvement of ’ features and content, including expanded integration with our other product lines, and ,” stated Yaron Guan-Golan, Head of Marketing at LifeMap Sciences. “We are also looking forward to working with Lost Island Labs’ Utopia to provide the research community improved access to via elegant deep links in a wide array of scientific publications.”
