Researchers ID Cancer Gene-Drug Combinations Ripe for Precision Medicine

Yeast, human cells and bioinformatics help develop one-two punch approach to personalized cancer therapy —

In an effort to expand the number of cancer gene mutations that can be specifically targeted with personalized therapies, researchers at University of California San Diego School of Medicine and Moores Cancer Center looked for combinations of mutated genes and drugs that together kill cancer cells. Such combinations are expected to kill cancer cells, which have mutations, but not healthy cells, which do not. The study, published July 21 in Molecular Cell, uncovered 172 new combinations that could form the basis for future cancer therapies.

“Oncologists here at Moores Cancer Center at UC San Diego Health and elsewhere can often personalize cancer therapy based on an individual patient’s unique cancer mutations,” said senior author Trey Ideker, PhD, … Read the Full Story by Heather Buschman from the UC San Diego Newsroom

Genetic Changes that Cause Autism Are More Diverse Than Previously Thought

Researchers find that the genetic causes of autism consist of a wide variety of genetic changes —

The types of gene mutations that contribute to autism are more diverse than previously thought, report researchers at University of California, San Diego School of Medicine in the March 24 online issue of The American Journal of Human Genetics. The findings, they say, represent a significant advance in efforts to unravel the genetic basis of autism spectrum disorder (ASD). …Read the Full Story from the UC San Diego Newsroom

The Role of “Master Regulators” in Gene Mutations and Disease

Researchers identify key proteins that help establish cell function

Researchers at the University of California, San Diego School of Medicine have developed a new way to parse and understand how special proteins called “master regulators” read the genome, and consequently turn genes on and off. … Read the full story from the UC San Diego News Center
