    Dissecting the ‘undruggable’

    Researchers at Harvard have designed new, highly selective tools that can add or remove sugars from a protein with no off-target effects, to examine exactly what the sugars are doing and engineer them into new treatments for “undruggable” proteins.

    Toward genetic editing

    Led by David Liu, professor of chemistry and chemical biology, a team of Harvard researchers developed a system that uses commercially available molecules called cationic lipids to deliver genome-editing proteins into cells.

    Neurons at work

    Using genetic tools to implant genes that produce fluorescent proteins in the DNA of transparent C. elegans worms, Harvard scientists have been able to shed light on neuron-specific “alternative splicing,” a process that allows a single gene to produce many different proteins.

    Viewing how neurons work

    A new technique for observing neural activity will allow scientists to stimulate neurons and observe their firing pattern in real time. Tracing those neural pathways can help researchers answer questions about how neural signals propagate, and could one day allow doctors to design individualized treatments for a host of disorders.

    ‘On’ switches for cells

    Scientists at Harvard have identified a previously unknown embryonic signal, dubbed Toddler, that instructs cells to move and reorganize themselves, through a process known as gastrulation, into three layers.

    A foundation for future research

    Harvard researchers recently developed the most detailed “specificity profile” for Cas9 — a “machine” made of protein and RNA that can be programmed to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes. Future researchers will use the data when developing genetic tools and therapies.

    Molecular motion in detail

    In a critical breakthrough in unraveling how molecular “motors” ferry proteins and nutrients through cells, Harvard scientists have produced high-resolution images that show how the chemical “foot” of dynein — one of the most complex, but least understood such motors — binds to microtubules, the cellular structures it travels on.

    Link found between ALS and SMA

    Scientists have long known the main proteins that lead to the development of amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA), respectively. Now research shows that these two motor neuron diseases likely share a pathway that leads to the development of disease.

    Turing was right

    Researchers at Harvard have shown that Nodal and Lefty — two proteins linked to the regulation of asymmetry in vertebrates and the development of precursor cells for internal organs — fit a mathematical model first described by Alan Turing six decades ago.

    Genetic mechanics

    As reported in the online version of Nature Structural & Molecular Biology on Feb. 5, researchers have produced 3-D images of the protein system that works to repair DNA. The images reveal that the proteins can actually alter their shape in what amounts to a genetic “pat-down,” or a way for the mechanism to identify…
