Long noncoding RNAs control development of fat cells

February 13, 2013

Whitehead Institute researchers report that 10 long noncoding RNAs (lncRNAs) play a vital role in the regulation of white fat cells. When each of these lncRNAs is individually knocked down, fat precursor cells fail to mature into white fat cells and have significantly reduced lipid droplets compared with white fat cells with unmodified lncRNA function.

Paired genes in stem cells shed new light on gene organization and regulation

February 4, 2013

Research from Whitehead Institute shows that transcription at the active promoters of protein-coding genes commonly runs in opposite directions. This leads to coordinate production of both protein-coding messenger RNAs (mRNAs) and long noncoding RNAs (lncRNAs).

Scientists expose new vulnerabilities in the security of personal genetic information

January 17, 2013

Using only a computer, an Internet connection, and publicly accessible online resources, a team of Whitehead Institute researchers has been able to identify nearly 50 individuals who had submitted personal genetic material as participants in genomic studies.

Modified antibodies trigger immune response, point to novel vaccine design strategies

January 7, 2013

In an approach with the potential to aid therapeutic vaccine development, Whitehead Institute scientists have shown that enzymatically modified antibodies can be used to generate highly targeted, potent responses from cells of the immune system.

Nutrient-sensing enzymes key to starvation response and survival in newborn mammals

December 23, 2012

One enzyme, RagA, has been found to regulate the mechanistic target of rapamycin complex 1 (mTORC1) pathway in cells according to glucose and amino acid availability. When this regulation breaks down in fasting newborn mice, the animals suffer a nutritional crisis and die.

Cell surface transporters exploited for cancer drug delivery

December 2, 2012

According to Whitehead Institute researchers, a protein known as monocarboxylate transporter 1 (MCT1), which is highly expressed in a subset of metabolically altered cancer cells, is needed for the entry of the investigational cancer drug 3-bromopyruvate (3-BrPA) into malignant cells.

Whitehead scientists identify major flaw in standard approach to global gene expression analysis

October 25, 2012

Whitehead Institute researchers report that common assumptions employed in the generation and interpretation of data from global gene expression analyses can lead to seriously flawed conclusions about gene activity and cell behavior in a wide range of current biological research.

Study reveals rate at which key genetic deletions contribute to male infertility

October 25, 2012

A large-scale analysis of Y chromosomes from more than 20,000 men finds that two spontaneously recurring deletions along a complex region of the Y chromosome are responsible for approximately 8% of cases of failed sperm production.
