Induced pluripotent stem cells (iPSCs) may hold the potential to cure damaged nerves, regrow limbs and organs, and perfectly model a patient’s particular disease. Yet these cells can acquire serious genetic and epigenetic abnormalities that lower the cells’ quality and limit their therapeutic usefulness. Now Whitehead Institute researchers have identified a cocktail of reprogramming factors that produces very high quality iPSCs.

Master heat-shock factor supports reprogramming of normal cells to enable tumor growth and metastasis
July 31, 2014
Long associated with enabling the proliferation of cancer cells, the ancient cellular survival response regulated by Heat-Shock Factor 1 (HSF1) can also turn neighboring cells in their environment into co-conspirators that support malignant progression and metastasis.

A team of Whitehead Institute researchers is bringing new levels of efficiency and accuracy to one of the most essential albeit tedious tasks of bench science: pipetting.

Embryonic stem cell (ESC) research has been hampered by the inability to transfer research and tools from mouse ESC studies to their human counterparts, in part because human ESCs are “primed” and slightly less plastic than the mouse cells. Now researchers in the lab of Whitehead Institute Founding Member Rudolf Jaenisch have discovered how to manipulate and maintain human ESCs into a “naïve” or base pluripotent state similar to that of mouse ESCs without the use of any reprogramming factors.

A signaling pathway once thought to have little if any role during embryogenesis is a key player in the formation of the front-most portion of developing vertebrate embryos. Moreover, signals emanating from this region—referred to as the “extreme anterior domain” (EAD)—orchestrate the complex choreography that gives rise to proper facial structure.

The protein CENP-A, which is integrated into human DNA at the centromere on each chromosome, has a vital role in cell division. Work from Whitehead Institute Member Iain Cheeseman’s lab describes how the vital and tightly controlled replenishment of CENP-A progresses.

Whitehead Institute scientists have genetically and enzymatically modified red blood cells to carry a range of valuable payloads—from drugs, to vaccines, to imaging agents—for delivery to specific sites throughout the body.

Metastatic cancer cells, which can migrate from primary tumors to seed new malignancies, have thus far been resistant to the current arsenal of anticancer drugs. Now, however, researchers at Whitehead Institute have identified a critical weakness that actually exploits one of these cells’ apparent strengths—their ability to move and invade tissues. Their research could inform novel approaches to screening tumors for personalized therapy or to drugs that specifically target these cells.

The lab of Whitehead Member Terry Orr-Weaver has conducted perhaps the most comprehensive look yet at changes in translation and protein synthesis during a developmental change, using the oocyte-to-embryo transition in Drosophila as a model system. One of the insights from this research is that a surprisingly large number of mRNAs that are translationally regulated.

Whitehead Institute researchers have identified a potential dual-pronged approach to treating Niemann-Pick type C (NPC) disease, a rare but devastating genetic disorder. By studying nerve and liver cells grown from NPC patient-derived induced pluripotent stem cells (iPSCs), the scientists determined that although cholesterol does accumulate abnormally in the cells of NPC patients, a more significant problem may be defective autophagy—a basic cellular function that degrades and recycles unneeded or faulty molecules, components, or organelles in a cell. Here, the scientists propose two drugs, one to reduce cholesterol buildup and the other to induce autophagy, as a strategy for treating NPC.
